    Marian Wang

    Access to a building where people live or work is restricted. Problems can pop up out of nowhere, like visiting a potentially dangerous location. Client expectation matching and management. Planning ahead is essential to get the necessary scans. You still need to work out how many scans you need and from where to have enough scan coverage even if you’re using cloud-to-cloud targetless registration. Actually, planning out the number of scans is crucial due to error propagation (especially in the setting of targetless registration).

    When you take the time to plan ahead, you can determine the best places to scan in order to meet the needs of your project without sacrificing quality or precision. The four main results your site strategy should accomplish are:

    The required quantity of scans
    Whether or not color scan information is necessary
    Scans on-site with restricted access or scans with local constraints and heavy traffic might be challenging to do due to idiosyncrasies of the site location.
    Planning a site from scratch takes a lot of time. Therefore, it is critical that as few scans as feasible be performed to capture as much data as possible from the spot. Following these suggestions should set you on the right track.

    In what situations are First Article Inspections performed, and why?
    Industries including aerospace and military, automobile manufacturing, electrical and electronics, and medical device production are common places to see first item inspection in practice. In these fields, accuracy is of the utmost importance, and the exact measurements of manufactured components are crucial.

    The aerospace sector must adhere to the AS9102 standard, which outlines certain processes that must be followed.

    Before moving on with manufacturing and filling out the remainder of the purchase order, it is important to do a thorough FAI to guarantee that all equipment, settings, and materials are satisfactory. By doing so, the firm is able to cut down on waste and the need for expensive and time-consuming reworks.

    Tests like this may often be performed by a technician or the QC staff at the facility, however third-party QC businesses like ours can step in to aid if necessary.

    When depending on a manufacturer for an FAI, it is essential that you have faith in their quality management system as a whole (QMS). Because of this, you should always check out a manufacturer before doing business with a new vendor.

    Bear in mind that FAI is not a perfect fit for every product or every industry.

    A pre-shipment or DUPRO inspection is usually sufficient for low-priced consumer goods.

    in reply to: What Methods Used in Automotive Quality Assurance #2202
    Marian Wang

    It’s safe to assume that most individuals don’t give much thought to their automobiles on a daily basis, unless, of course, they are true automotive enthusiasts. Most consumers see automobiles strictly as utilitarian items. And, like the toaster or blender sitting on your kitchen counter, automobiles don’t seem to take up a lot of room in their owners’ minds. I mean, until the automobile stops working.

    It’s true that there have been several high-profile recalls recently, but overall, vehicle dependability is higher than ever. That’s because vehicle producers have started to grasp a vital phase in automotive manufacturing: quality control. Quality control is a method used in almost every business to guarantee that a service or commodity is faultless in every way. When it comes to the production of automobiles, this means that each model is put through a battery of tests to ensure its engineering, safety, and passenger comfort.

    Quality assurance is performed well before the first vehicles leave the factory. Prototypes are created before a new vehicle is released so that flaws, mechanical issues, and other elements may be fixed upon before mass production begins. After the prototype has been thoroughly tested and improved, the design enters production, where quality control checks are conducted at regular intervals throughout the assembly line. After being produced, each automobile is examined for faults including fluid and air leaks, mechanical difficulties and appropriate assembly.

    Controlling Quality in Automobiles
    Quality control is something that’s a critical aspect of practically every sector and every employment. Several times a day, you do your own kind of quality assurance. Proofreading an email before sending it is an example of quality control. This article, too, is the product of some kind of quality assurance procedure. The editor responsible for uploading the piece to the website will review the final product for typos, improperly sized images, and broken links, among other things.

    The production of automobiles follows a similar procedure. However, quality control cannot be performed until the product has been constructed. That’s why the first step in ensuring consistent quality in the production of automobiles is checking out the model’s prototype. After that, testing begins on the prototype.

    Multiple tests, developed by engineers, are used to evaluate a vehicle’s durability in real-world (and harsh) conditions. For instance, they put the prototype car’s suspension through its paces by driving it over specialized terrain meant to stress it. They also drive the vehicles in harsh temperatures to ensure that all of the vehicles’ mechanical parts function reliably no matter what the climate throws at them. When inspecting a vehicle for leaks, they will even use smoke to make sure all the windows and doors are properly sealed.

    The crash test is a famous example of a quality control test. Many people are aware of government and insurance industry crash testing, but they may not know that automakers also conduct their own tests to guarantee that their goods and safety systems will function as intended and keep passengers safe.

    After the inspection and control of incoming materials, we will talk about the process quality control. As we all know, the production process in the narrow sense is composed of 4M1E people, machines, materials, methods and rings. We will discuss these 5 aspects separately below;

    1. Human, many people say that human is the biggest variation in the process and the biggest variable in management, which is true. Under the premise that all automation can not be realized, it is particularly important to improve the ability of front-line operators and grass-roots management personnel. Each enterprise will have its own training mode. Based on the author’s experience, this paper introduces a method that I think can be called best practice;

    For operators, after regular induction training, HR shall assign appropriate posts according to their age, gender, education level, etc. before the formal launch, HR shall carry out practical operation of corresponding posts in HR’s practical training room. After passing the on-site examination, HR shall file in OA system, and then transfer to the production line for operation. After being assigned to the post, The on-site team leader will arrange skilled employees (more than 3 professional skills) to carry out on-the-job OJT training to ensure that they can keep up with the online speed and can carry out independent operation. After three months of independent operation, they can apply for the examination for professional skills. After obtaining three professional skills, they will automatically enter the multi-functional library as a reserve for the front-line grass-roots management personnel;

    (Note: the post allowance will be increased by 50 yuan for each professional skill tested. The specific number of professional skills can be set according to specific products and processes)

    For team leaders, inspectors and other grass-roots management personnel, all grass-roots management personnel must be selected from the multi-functional library. After passing a series of training and examinations, they can apply for job transfer interviews to become grass-roots management personnel. Among them, quality related courses are compulsory courses, such as the basic concept of quality, the seven major methods of new and old QC, and SPC introduction. For team leaders, training of manufacturing grade, such as IE related courses and 5S management courses, will be added, Comprehensively improve the skills and quality awareness of front-line grass-roots management personnel from all dimensions.

    After the completion of these routine trainings, continuous rolling OJT trainers are indispensable. OJT training materials come from the LLC formed by customer complaints, customer audit findings and quality accidents in the manufacturing process. This material is used for rolling training to form a long-term mechanism, so as to improve the quality awareness of on-site personnel and finally form a quality control atmosphere for all employees.

    2. Machine: in the process of process design and development, formulate acceptance standards for machines and equipment, conduct CMK analysis on process parameters related to special characteristics of products, and ensure sufficient process capacity; MSA analysis is required for measuring equipment, including instrument calibration and GR & R analysis;

    3. Material is controlled by incoming materials, which will not be described here;

    4. Method. The method is divided into operation method and control method. The operation method is embodied in SOP. The control method is defined by the control plan and controlled by various forms on the site, such as the start of shift check OK, equipment check list, parameter check list, PQC process patrol check, etc

    5. Environment in the narrow sense refers to the working environment, including the temperature, humidity, light intensity, etc. of the site

    In a broad sense, the environment includes the working atmosphere and interpersonal relationship within the organization;

    The purpose of inspection is to find variation. Whether it is in incoming inspection, process inspection or finished product inspection, we are all to find variation, control variation and reduce variation. Where is the largest source of variation? Every factory has its own set of methods and processes for 4m change. Based on the author’s experience in the automotive industry for many years, foreign-funded Tier1 is cautious about 4m changes. A joint-venture main engine factory has shared all its market complaints in 2019, of which nearly 70% are caused by the supplier’s change management. The author once submitted an application for changing the supplier of parts, and the main engine factory took half a year to approve it. During this period, the whole PV test verification, on-line trial assembly and new project development were almost the same.

    Do a good job in the four modules of incoming inspection control, process inspection control, finished product inspection control and change management, and the whole product quality control work will be relatively perfect. How to convert the inspection data into the input for quality improvement is a topic we will discuss in the future. Quality improvement!

    First question: the data required for the pre shipment inspection certificate is the same as the data room required for the commodity inspection. The data provided during the commodity inspection can be directly used for the pre shipment inspection certificate. However, since the pre shipment inspection certificate will list all the goods loaded into the container, it is better to make a specific list to the Commodity Inspection Bureau if your products will carry some small parts.

    Second and third questions: since it is a pre shipment inspection certificate, we will certainly come to inspect the goods before shipment. We will also investigate whether the price of your goods is appropriate and whether it is too low or too high. If the price is unreasonable, the Commodity Inspection Bureau will ask you to write a certificate. When the goods are loaded into containers, you ask the teachers of the commodity inspection bureau to supervise the loading. Photos will be taken during the loading supervision. After the goods are loaded into the container, the Commodity Inspection Bureau will put a lead seal on the container (the lead seal of the Commodity Inspection Bureau, and the commodity inspection department of the other party will open the case for inspection after the goods arrive at the port of the other party). The most important thing is to ensure that the goods are consistent with the certificates, otherwise the customs clearance will be cumbersome

    The fourth question: if you make a receipt, you don’t need to make a customs clearance slip. The purpose of the receipt is that your freight forwarder will exchange the customs clearance slip for you at the customs declaration port.

    Fifth question: if the commodity inspection bureau is acting according to the regulations, it should supervise the loading first, and then issue the pre shipment inspection certificate to you after your goods are delivered. The goods certificate must be consistent. You want your certificate to say that you exported 20 cars. In the end, the other party’s commodity inspection bureau only opened the box for inspection. Is that ok?

    It’s very troublesome to export to Egypt. I only went to the commodity inspection for one week… In addition, it is likely to be countersigned… What our customers asked to do at that time was to countersign the invoice, certificate of origin and pre shipment inspection certificate, which took about one week. Therefore, it is better to confirm with the customer in advance so as not to be too late

    in reply to: What are top suggestions for conducting factory audits? #2073
    Marian Wang

    Production procedures are not necessary to conduct supplier factory audits. Using a Factory Audit Checklist, you may swiftly assess the factory’s quality control system and other elements of operations. An even better option would be to use a mobile application, but we’ll get to that in a moment.
    Auditing a Supplier Factory: Tips for Success
    1. Create a strategy – Make a clear goal for your audit of a supplier’s manufacturing facility before you begin. Make sure the audit is comprehensive and valuable by using this method.
    2. Keep your ideas and materials in order before the audit so that nothing is overlooked.
    Establishing a connection with the supplier’s management before to the audit will make it simpler to communicate during the actual audit.
    3. Prepare yourself for the audit by familiarizing yourself with the supplier’s business processes. This will help you spot possible problems during the audit.
    4. Don’t only concentrate on quality or compliance concerns when evaluating a supplier’s factory; it’s crucial to acquire a holistic view of the plant.
    5. Immediately discuss any concerns or results from the audit so that quick action may be taken to remedy the situation.
    6. After the audit is done, it is critical to follow up with the supplier to verify that any errors found have been resolved.
    7. Your audit should be documented using a flexible reporting system. First Reporting is one of the most flexible reporting systems on the market. To utilize it, you may use it in factory and facility audits, as well as in any other situation where a form or checklist is appropriate. Using a cloud-based software is ideal for field technicians, firms with several locations and divisions, and even those that use a lot of forms or checklists.

    Performing an external audit at your company may seem like a terrifying prospect. As a general rule, most individuals and companies dislike being audited by an outside entity. As a company owner, you must guarantee that your goods, processes, and services meet or exceed industry standards. Auditing your factory, whether it’s by an outside agency or by yourself, doesn’t have to be an unpleasant event. Performing a quality audit effectively and preparing a detailed audit checklist will make it just like any other quality control that your organization does.It is critical to conduct a factory audit to ensure compliance with all applicable regulations, especially if you’re working with a different company.

    Performing an external audit at a company seems like a terrible idea. Being audited, particularly by an outside body, is a source of anxiety for many individuals and corporations. The standard quality goods, processes, and services are an essential aspect of every organization. A factory audit does not have to be a stressful experience, regardless of whether an external organization is auditing your company or if you are organizing your own. A quality audit will be no different than any other form of quality control in your company as long as you do your job well and prepare the audit checklist thoroughly.

    In this post, we’ll discuss some of the most important aspects of conducting a factory audit. Serious infractions are subject to a zero tolerance policy. It’s critical to have an audit checklist so you know exactly what needs to be assessed and when. You may allow a small deviation from your quality audit checklist while conducting your own factory audit. Although it may seem like a minor flaw, if your factory is a supplier to other businesses, it could result in a supplier audit failure. External audits often call for more stringent regulations and zero tolerance for serious infractions. Consequently, it is critical to comply with any rules or requirements imposed by the government, clients or other business associates. This includes verifying mandatory licenses and certificates, as well as prohibiting any form of child or forced labor.

    Basic upkeep of buildings, their surroundings, and their equipment
    Basic facility, environment, and equipment maintenance should be on every audit’s to-do list. You’ll need to take a complete tour of the facility to complete this checklist item. This will guarantee that every aspect of the plant, from the operations to the environment, meets the needed level.

    The organization of the quality management system
    As part of a successful factory audit, the quality management system should also be examined. Your partner will be able to check whether your factory is meeting their quality requirements by using these auditing points.

    Control of the quality of goods and services
    From raw materials to final goods, a factory audit is a critical tool for gauging the overall quality of your operation’s output. Your partner will be able to gauge the quality of your items thanks to quality controls.

    Practices in human resources recruiting and education
    Future products will be delayed and of worse quality if factories have a high turnover rate. Temporary employees without proper training or contracts may potentially have a negative impact on productivity. An audit checklist should include a point to confirm that the individual working there is properly qualified and trained.

    Capabilities in engineering, design, and research
    Having an engineering, research, and design staff on hand is almost certainly a need if you want to work with importers. Even though it isn’t required, these teams are often welcomed by the companies they work for.

    Candy sales fell 14% in the summer of 2006 due to a widespread salmonella outbreak that lost a British confectionery company £20 million. In 2007, a recall of 60 million cans of dog food shook the pet food market in the United States. In the early months of 2019, a car manufacturer was forced to recall 44,000 vehicles because of carbon dioxide levels that were not approved. For a kitchen equipment business, returning 15,000 defective microwaves was just the latest in an ongoing series of costly recalls due to defective products.

    Even though well-established firms often have the financial wherewithal to recover from short-term setbacks like product recalls, there’s always the possibility that poor news might be the death knell for even the most powerful of brands. Preemptive quality control checks may have saved millions of goods and millions of dollars in earnings if the companies had paid a fraction of these expenditures.

    The best way to avoid problems is to take steps to prevent them in the first place.

    To avoid this, it is necessary to mediate and monitor the production process with quality control inspections from start to end, as well as watching the final packaging and shipping preparations. To better understand quality control in manufacturing, we’ll look at the many methods of inspection.

    Quality Control Services Inspection Types: What Are They?
    To verify that the production process and products fulfill the agreed-upon criteria, quality control professionals visit plants on behalf of clients.

    It’s important to have quality control services in place to make sure that your products satisfy your standards and to keep an eye on the supply chain’s impact on the quality of your products.

    It is possible to use the internationally recognized statistical sampling procedure ANSI/ASQC Z1.4 (ISO 2859-1) in order to determine the percentage of a batch of products that must be examined for quality in order to represent the overall quality of the batch, commonly known as the Acceptable Quality Limit (AQL) (AQL).

    Checklists should be provided to inspectors by the manufacturer or supplier in order to establish the acceptable quality tolerance level for faults or non-conformity.

    Identifying and Correcting Errors
    Products (units) that do not meet the intended purpose of the product are marked during the factory inspection process to look for flaws. ANSI/ASQ A3534-2-1993 checklists are used by on-site quality control inspectors to assign a severity rating to any faulty units.

    Illustrations of Flaws
    A garment’s buttonhole and button do not line up.
    Unsatisfactory product or component of a product
    Mistakes in the use of incorrect or illegal materials
    Making a Case for Non-Compliance

    It is determined whether a finished product (unit) has met the customer’s specifications via factory inspection for non-conformity. The level of severity of any features that do not match established norms is noted on inspected units.

    Non-Compliance with Specifications
    Wrong measurements.
    Dimensions do not correspond to industry standards.
    Power input/output that is not appropriate for the target market

    According to the WHO Food Code, food inspections are conducted on processed and perishable goods (Codex Alimentarius).

    in reply to: What is pre production inspection #1950
    Marian Wang

    PPIs are a specific kind of quality control procedure. Many companies rely on them when they begin working with new suppliers or enter into large contracts. With a pre-product inspection, it’s easy to guarantee that your supplier is not reducing costs and you’re getting the items you deserve.

    Exactly what is the purpose of a pre-production quality control inspection
    After you have chosen a vendor or factory, you conduct pre-production inspections. Their primary goal is to identify potential issues with product quality prior to the start of production. Before production begins or before final assembly begins, you may conduct a pre-production inspection.

    Using a PPI gives you the following advantages
    A thorough awareness of production timelines
    Being able to foresee and avoid problems that could delay a project or degrade its quality
    Assuring you that your needs will be fulfilled
    Assurance of the quality of raw materials and the components of the final product

    What Is the Importance of Pre-Production Inspections?
    Pre-production inspections are a key component of risk assessment and quality assurance management. Prior to starting production, you need to make sure that your supplier can start, fulfill your specifications and maintain the quality standards that you have set. This is impossible without a pre-production inspection.

    Many advantages accrue to your company as a result of these examinations. conduct pre-production checks for you when you engage a person or a company
    Reducing the risk of supply chain disruption
    Verify the manufacturing readiness of your supplier
    Your manufacturer’s capacity to satisfy your requirements and quality standards may be evaluated by this method.

    When Is A Pre-Production Inspection Right For My Company?
    Pre-production inspections may help businesses in a variety of ways. Although they aren’t always the best strategy to ensure that production begins on schedule, they are a good starting point.

    Additionally, pre-production inspections provide you an overview of some of the most crucial aspects of the manufacturing process. If you need to know more about the materials for your project, prospective prototypes, and/or mass production, you may consider a pre-production examination.

    While a pre-production inspection may be necessary for some projects, an examination during the manufacturing process may be more beneficial.

    A quality control chart can be used to randomly pick and test inspection products based on a certain property or qualities. This image shows whether or not the company’s quality criteria are met, and if not, how much deviation there is from those standards. It is possible to use the graphs to look at a single characteristic or a variety of product attributes at once. Companies can tell if errors occur at random or in a predictable way by examining the chart’s pattern. Multivariate and univariate charts are two different types of charts that quantify the variation in numerous product parameters. Companies typically utilize X-bar charts for quality control, however they may also employ:

    Graphic representations of causal relationships
    Graphs of control
    The following are some examples of run charts:
    Spread schematics all over the place.
    Quality control using the Taguchi technique

    Defects and faults in products may be reduced by focusing on product development, product design, and research and development. It aims to prevent production discrepancies by focusing on design rather than manufacture.

    Inferential statistics
    In this method, a subset of all items is measured, and then conclusions are drawn about the remaining products based on those results.

    in reply to: Cnc routing uses different methods of cutting? #1623
    Marian Wang

    Make sure you know which category your cut fits into since you will need to specify the type of cut in the CAD program that you are using. As a result, each form of cutting requires certain drill bits, and the machine operator must take into consideration certain factors to get the desired results.

    Cuts for Men
    The cut around the object is called a “male cut,” and it refers to the last cut in a component that allows it to be removed from the material. In order to verify that the final product’s measurements, such as width and height, are accurate, a male tool path is cut from the outside of the part. Even the tiniest router bits have a diameter, making it hard to create sharp inner corners. As the operator would never be able to reach a true inside corner with a 90o angle, this must be considered for male cuts going inside corners.

    Cuts for Women
    A female cut is the polar opposite of a masculine cut, as one might expect. A female cut is made from the inside of the item or from the material to be removed from the object. Because of this, the CNC software will always provide a tool path with slightly rounded inner corners for female-cut objects, just like it does for male-cut ones.

    Cutting in the middle
    Using the CAD software’s On Center or Online cutting mode, the bit is guided by the center of the vector shape as it is generated. On center cutting does not necessitate the use of a polyline since the bit does not need to locate the “sides” of the cut. One or more lines (or arcs) are used to create a polyline in AutoCAD. Shapes that have previously been cut and require additional cutting, such as beveling with a V-bit, are most commonly beveled utilizing on-center cutting.

    This is comparable to cutting all the way through the material and milling out a shape, except instead of doing so, the cutter only cuts to a specified depth before milling out a shape. Materials can be grooved or 3D-routed using cleanouts. Materials that will not deform during cutting are ideal for 3D routing, but the procedure might take a long time to complete since the drill bit must clear a specific spot several times. It’s best to use bigger bits when clearing out a broad region to save down on cutting time.

    As with Female cutting, drilling involves making an incision inside the object. Drilling, on the other hand, is intended solely for the purpose of making holes, and each hole is precisely the same size as the bit used to make it. Drilling might imply routing the material completely through or only partially so that a countersink hole can be created in the material.

    Since quality control inspection is a key element of any production process, it’s important to note. Find out which QC inspection tasks are most critical and how a certain digital tool might help with those tasks..

    So, just what does “Quality Control” imply?
    (QC) Product or service quality may be maintained by a process known as quality control, which ensures that customers receive the best possible product. In order to ensure that clients obtain products and services of the highest quality, quality control is essential (SOPs).

    Establishing Product Quality Requirements
    Each company’s products or services have their own checklists or task lists. Quality measurement is the initial stage in setting the product’s quality standard. To guarantee that every step is done in the proper direction, the company’s quality standards must be constantly monitored.

    Identifying the Methods
    When it comes to quality control, several methods for inspecting and testing are used. Products from well-known companies are tested using specified standards. Use the information in this manual while conducting quality tests.

    How Many Products Have Been Tried Out?
    Only a small percentage of products are subjected to quality control checks. A certain number, volume, or batch is selected for quality control measures. Test batches must correctly represent larger quantities of the product.

    Establishing a Communication Plan with Team Members is the fourth step in the process.
    Quality control is a team effort. Everyone involved in the production process must be kept up to date on project progress by a quality control manager. An assessment method is included in addition to a contact list and regular meetings.

    5. Taking Advantage of Manufacturing Technology Advancements
    Quality control may be improved with the usage of digital checklists. Since QC inspections necessitate the exact application of processes, a checklist helps guarantee that every task is executed to the greatest possible quality. As a result of the use of Nimbly’s automated checklists, management and quality control may be ensured.

    The 3D inkjet printing technique is similar to other 3D printing technologies in that it occurs by layer-by-layer deposition. Printing instructions in each layer are created from a 3D mechanical model for your product, much as is done with popular fused deposition modeling (FDM) systems. However, this proven additive manufacturing technology is unusual in that it is scalable to a broad variety of liquid materials or solid suspensions, generating conductive or insulating structures with excellent printing precision. Inkjet printing needs no post-processing, as opposed to methods involving the fusing of metals or plastics; the printed object is ready to use as soon as it exits the printing equipment.

    If you’re considering 3D inkjet printers for additive manufacturing, it’s critical to know the benefits and advantages of the technology. 3D printing circuits is the primary emphasis of this digital manufacturing technique.

    The workings of 3D ink jet printing
    3D inkjet printing is a low-temperature, low-pressure technology that includes the deposition of liquid materials or solid suspensions. This technique can deposit polymers, dielectric nanoparticles, and conductive nanoparticles, making it versatile. A tiny nozzle within a print head is used to extrude the printing material during this procedure. As the print head raster scans across a surface, several layers are built up in a layer-by-layer process.

    Each deposited layer must be cured in between subsequent depositions, and the curing procedure will vary based on the materials used to print your product. Each layer of an inkjet 3D printing system has its own equipment for curing it. While the requirement to cure each deposited layer in between depositions may seem time consuming, the deposited layers are extremely thin and may be cured fast, ideal at low temperature or with an optical process (such as exposure to infrared or ultraviolet radiation) (such as exposure to infrared or ultraviolet light).

    Printing resolution is an essential element in every 3D printing system since this dictates the lowest feature sizes and tolerances that can be successfully deposited using your system. The limiting elements that decide in the 3D inkjet printing process include the droplet size, which is governed by the size of the nozzle in the print head. In general, better resolution is achieved with a smaller nozzle (i.e., smaller printed features). High-density, high-layer-count PCBs may be additively manufactured using 3D inkjet printing because it produces high-resolution conducting and insulating structures from a variety of materials.

    Pros & cons of 3D inkjet printer
    When it comes to selecting an additive manufacturing technique and system for 3D printing PCBs, there are certain crucial elements to consider:

    Resolution: This specifies the precision of printed insulators and conductors, and becomes particularly critical for designers who wish to construct PCBs with a unique connection architecture or high-density conductor.

    Surface finish: With DC circuits, surface quality is a minimal performance influence. Rough conductors, on the other hand, may cause challenges including frequency mixing at high intensity, signal reflections at rough places on the surface, and trouble with impedance control routing across a PCB in analog circuits running at RF frequencies, extremely high-speed circuits, and antennas.

    Throughput: This describes the productivity of the process and is actually connected to the speed with which materials may be deposited. Using a multimaterial inkjet technique lowers the number of production stages to one printing phase. In contrast, standard PCB manufacturing processes involve multiple intermediary assembly stages during manufacture.

    The throughput of a process might be adversely affected by the limitations on the types of materials that can be processed. Some printing procedures need many printing stages, while others are ineffective with certain types of materials.

    Choosing the proper additive manufacturing technique demands striking the perfect balance among these aspects. There are significant limitations to inkjet printing as a manufacturing technique, and as a result, components produced using this method may not be strong enough to be used in some particularly demanding mechanical applications.

    However, inkjet printing is an appealing approach for electronics for a variety of reasons. Regarding 3D printing of PCBs, the multimaterial end-product (conductive and insulating materials) is conveniently produced by means of several printheads, the variety of needed materials is rather restricted, while the resolution and surface polish requirements are severe. Inkjet printing can meet these criteria for a wide variety of electronics applications.

    in reply to: What Are The Workflows For Quality Assurance #1472
    Marian Wang

    Designing a quality assurance process that is both fast and dependable is essential to reducing mistakes. Regardless of how large or little your business is, or whether you’re a one-man show, I’ll teach you precisely how to achieve it in this post.

    Just four simple steps to get us started with Quality Assurance
    We intended to make the QA process as easy as possible for a small or medium-sized web development company. Keeping in mind that we are just human should be at the forefront of every decision we make. By having a clear and consistent structure in place, even the most detail-oriented individual will be able to do more than they can by themselves.I’ve outlined the four stages of the quality assurance process that we use. In our experience, this is a good fit for our needs.

    Talented and Appropriate
    In order to get the ball rolling, the first obstacle to overcome is deciding who would do the quality assurance evaluations. We would rectify our own faults if they were easily seen. It’s essential to have a fresh set of eyes go through the project since it’s difficult to execute.

    Hiring a QA expert is the greatest solution if your firm has the resources to do so. There is no way for them to miss anything since they are so immersed in the project. In addition, an expert is likely to become more efficient and effective at their work than an individual who just checks for faults once in a while.

    Hiring a QA professional may not be feasible for a small organization. The post was just formed in the last year as we grew from a staff of 20 to a staff of over 50. Developers or team leaders may still maintain the notion of “fresh eyes” while working in a smaller firm.

    What if you’re a contractor? Build a few days into your schedule so that you may put a project on hold until the review is complete. Try something different for a time. When you return, you will be able to see the job with a fresh set of eyes.

    Creating a QA Checklist
    In the real world, checklists save lives. Using checklists in the workplace has shown to be a boon to both hospitals and airlines.

    The stakes are obviously lower when it comes to websites than they are when it comes to a person’s life. However, the underlying idea remains the same: checklists operate because people are incapable of accurately recalling a large list of activities from memory.

    Depending on the kind of job you conduct, the format of your checklist will differ. Creating a QA checklist template is a good idea if your tasks are a lot like constructing websites. Every project should use this template to cover the aspects that need to be tested or assessed for accuracy.

    Initiating the Process
    Now that you’ve got your quality assurance reviewer and a list of concerns to watch out for, you’re ready to begin. It’s all about how you put them together and develop your quality assurance process.

    An Ever-Evolving Process
    Our previous discussions have focused on how to ensure that your projects are error-free before they are sent out to customers for review. In order to reduce the amount of defects that make it to internal QA and then the customer, there are a few things that may be done.

    There may be recurring patterns of problems, although this is not always the case. You’ll need to gather stats to figure this out. The QA professional at your company might be assigned the task of classifying the problems that arise as they are discovered. Such data may then be used to offer ongoing feedback and testing for improvement from a single developer.

    Work out the details of your Quality Assurance Workflow
    When you’re trying to increase the quality of your company’s work, it’s not always feasible to accomplish everything at once. Things’s easier to make progress if you break it down into manageable chunks.
    Using “new eyes” while evaluating projects for their quality
    Compiling comprehensive and specific checklists
    Establishing a process for organizing tasks and identifying roles and responsibilities
    Whenever feasible, using measurements for continual improvement

    in reply to: What is the Definition of Third-Party Payment #1410
    Marian Wang

    The term “third party payment” refers to the process of making a payment via a method other than the recipient investor’s own bank account. If a payment is being made from a shared bank account, the first identified investor/holder of the mutual fund folio must be a joint account holder.

    The term “third-party payment processing”
    You need to know precisely what a third-party payment processing firm is before you can make an informed decision about whether or not it is suitable for you. Online or credit card payments may be accepted by retailers without the requirement for a merchant account using third-party payment processors (also known as payment aggregators).

    When it comes to running a company, third-party payment processing business organizations want to make things as easy as possible for merchants. No need to bother about keeping a merchant account this way. A third-party payment processor may handle all of your transactions for you if you register for an account with them.

    Understanding the inner workings of a third-party credit card processor
    Third-party processors deposit the proceeds from card payments into an aggregate merchant account, which may be used by several businesses. The remaining monies are sent to the small business’s bank account after the processor deducts processing costs.

    Third-party processors and merchant account providers vary primarily in the speed at which payments may be deposited into a company account. It may take several days for cash to go via third-party payment processors, but merchant accounts provide for rapid access.

    Third-party payment processors have complete control over how many merchants may use their merchant account at any one time. A single account may be shared by tens of thousands of businesses. Reliable third-party processors manage your cash and guarantee that each transaction is paid accurately, regardless of the quantity.

    Is it Necessary to Use a Third-Party Payment Processor?
    In the early stages of their business, many would-be entrepreneurs are unsure whether using a third-party payment processor is the best option for them. However, the fact that signing up is simple and free persuades them to do so. As a rule, third-party payment processors are only essential if you have a large volume of transactions to handle.

    Using a third-party payment processor has both advantages and disadvantages. For certain businesses, dedicated accounts may not be financially feasible. SMBs that handle a limited number of client credit card payments may not be able to afford the charges of opening a credit card processing account. You may save money by using a third-party payment processor when you’re just getting started and don’t expect to handle a lot of credit card transactions.

    Using a third-party payment processor has various advantages for organizations, such as:
    1. The setup is simple. An online company does not require a merchant account in order to accept payments from customers through a third-party payment processor, which is often a straightforward procedure.

    2.Reduced costs. Third-party processors often don’t charge startup fees or impose monthly minimums, unlike individual merchant accounts.

    3.Flexible terms. Merchant service providers sometimes need long-term contracts, whereas third-party processors frequently provide better terms or don’t require any contracts at all.

    4. One-stop shop. To get started fast, several third-party payment processors provide companies with the tools they need to collect payments in person, online, and at the point-of-sale.
