Printed Circuit Board Assembly

A circuit board prior to assembly of electronic components is known as PCB. Once electronic components are soldered, the board is called Printed Circuit Assembly (PCA) or Printed Circuit Board Assembly (PCBA) or PCB Assembly.

A printed circuit board assembly (PCBA) describes the finished board after all the components have been soldered and installed on a printed circuit board (PCB). The conductive pathways engraved in the laminated copper sheets of PCBs are used within a non-conductive substrate in order to form the assembly. Attaching the electronic components to the PCBs is the concluding action to create a fully operational electronic device.

Assembling a printed circuit board requires more than just the raw components and a well-designed board. It also requires the right technology. In this case, there are several options to choose from, and each brings something different to the table. For instance, there’s surface mount technology (SMT), as well as manual soldering, and the use of pick and place machines.

While some PCB assembly processes will require just one technology, others will require a combination of two or more technologies. For example, many boards require the combination of through-hole technology (THT) and surface mount technology. Understanding when, where, and how to integrate those technologies is a critical consideration when choosing a company to handle your project or production.

High volume PCB Assembly

Count on us for any kind of high volume PCB assembly requirements at unbeatable price! When it comes to PCB Assembly, the requirements vary in volume. If you are mass producing a product you would need high volume printed circuit board assembly service to meet your requirements. Typically projects of 10,000 pieces or more are classified as high volume PCB Assembly service and needs a dependable partner who can supply it.

Test methods such as Automatic Optical Inspection (AOI), Solder Paste Inspection (SPI), In-Circuit Testing (ICT), Functional Circuit Testing (FCT), and X-Ray inspection are selected based upon a client’s request, as well as the specific requirements for each large volume assembly projects. Design for Testing (DFT) becomes very important at large volume since ICT and FCT will likely be performed using a Bed of Nails test, rather than the Flying Probe test that is common at prototype and low volume. We also provide a free sample program for large batch turnkey orders, in which we will assemble a limited run of boards for approval by our clients prior to the majority of the order being completed. These quality control methods allow us to offer a full warranty on our PCBs; in the event of any board failures that are not due to design issues, we pledge to rework or replace any defective PCBs. This is part of our NPI strategy to work with our clients to ensure the quality and viability of their printed circuit boards prior to high volume production and assembly.

We utilize a robust NPI system which ensures close monitoring of new products from the quotation stage to final shipment. Throughout this process, we assess our client’s orders for manufacturability (DFM), testability (DFT), as well as the costs and turn-time from an engineering point of view. We are committed to working with our clients to provide design recommendations, which decrease overall costs and turn-time without sacrificing final quality of their orders. This is based on a variety of assembly and manufacturing capabilities provided by our production facility for high volume printed circuit board assembly. We can accommodate both SMT and THT assembly for a range of components and packages. For SMT we provide assembly for QFN, QFP, LGA, and BGA IC packages, plus many more, down to a pitch of 0.2mm with 0201 imperial (0603 metric) being the smallest passive component size.

Quick Turn PCB Assembly

Whether you are in a jam and you need your printed circuit board assemblies quickly, or you are in a rapid, fast-paced prototyping environment and need a quick turnaround on a regular basis, we are here to help.

The final lead time will depend on the complexity and quantity of the PCB assemblies you need. As circuit board assemblies get more complex (higher number of copper layers and component counts), the number of processes increase. Simple boards can be turned around next day, but more complex printed circuit boards will likely need longer lead times. Prototype assemblies that can be hand soldered will have quicker turnarounds compared to assemblies that need stencils, SMT programming, and tooling.

Our PCBA quoting team processes hundreds of RFQs each month, so making sure you have complete and correct documentation helps us continue to provide the high level of customer service we have become known for. Here are some of the issues we sometimes run into:

• Incomplete Bill of Materials (BOM): If we are sourcing components, we need BOMs to have complete manufacturer part numbers. If there are 1 or 2 missing part numbers, we can live with that. However, if the entire BOM is missing manufacturer part numbers, we ask that you complete the BOM before sending it in for quoting.
• Obsolete, non-stocked, or out of stock components: If we are sourcing components, and you are looking for a quick turnaround, one component that has a 12 week lead time is likely a show stopper. Help us know what our options are a head of time. For example, identify the hard to find components and let us know that you plan on supplying them or that we can Do Not Install (DNI) specific components.
• Missing components on the BOM: When we are quoting your PCB assembly, we review the BOM against the Gerber/Drill files. When we see parts that are on the board, but not on the BOM, we do not know if you accidentally forgot to put them on the BOM or if they are DNIs. This is important to know for our quoting process. Please add all parts to your BOM, but label them as DNI if they are not to be installed.

We maintain global quality standards throughout our electronic PCB assembly operations by performing rigorous checking, analysis and inspections. Owing to a rich industry experience, we have gained expertise in dealing with all kinds of PCB assembly orders, no matter how difficult your project may be. These are some of the reasons that have made us one of the leading and prominent sources for high quality and dependable PCB assembly services.

Surface Mount technology PCB Assembly

Surface mount PCBs assembly occurs when electrical components (surface-mount devices) are machine picked and mounted directly onto the surface of the PCB. During this process, thousands of electrical components are attached and connected to their contact pads using reflow soldering.

Nowadays, the majority of electronic assemblies are designed using surface mount components and technology. This is in part because SMT allows for increased quality and a reduction in manufacturing costs due to the high degree of automation.

However, surface mount assembly presents challenges to manufacturers which must be met through the astute selection of appropriate production equipment. This expertise allows us to design products which are completed in one pass down an automatic SMD assembly line without any extra hand assembly work other than to snap the circuit board into a moulded enclosure. Over the years, our electronic assemblers have optimised their methods to achieve a highly efficient SMT process that is second to none across the China.

Through hole PCB Assembly

Through hole PCB assembly is the process of mounting electronic components onto a printed circuit board (PCB) through holes drilled in the board. The through-hole mounting is used to connect the component leads to conductive pads on either side of the hole. This type of connection is commonly used for larger components, such as integrated circuits (ICs), that require more support than surface-mount components.

Through hole PCB assembly is a complex process that requires a high degree of accuracy and precision. The through-holes must be drilled with extreme precision in order to ensure that the through-hole components can be properly mounted onto the board. Once the through-holes are drilled, the mounting process begins in which the components must be carefully placed into the through-holes and soldered into place.

After the through-hole components are mounted, the PCB through hole assembly process is completed by connecting the through-hole leads to the appropriate conductive pads on the PCB. This connection can be made using a variety of methods, such as soldering with solder paste, welding, wave soldering, or brazing.

What is Electronics Manufacturing Services (EMS)?

The term “electronics manufacturing services” (EMS) refers to an overall industry and also to a specific class of subcontractor or company. EMS is also often used interchangeably with the more generic term “contract manufacturing (CM)”. In short, EMS companies provide a wide range of value-added engineering and manufacturing outsourcing services to original equipment manufacturers (OEMs), allowing them to improve operational efficiencies and focus on core activities like research and development (R&D).

Electronics manufacturing services (EMS) is a term used for companies that design, manufacture, test, distribute, and provide return/repair services for electronic components and assemblies for original equipment manufacturers (OEMs). The concept is also referred to as electronics contract manufacturing (ECM).

Electronics manufacturing companies are critical partners for Original Equipment Manufacturers (OEMs), who need expert assistance with assembly and supply chain management. The services of electronics manufacturers include the assembly of printed circuit boards (PCBA), the production of electronic modules, as well as the entire devices . Behind the success of many products introduced to the market is a professional and reliable supplier – an EMS company. Before we go further, let’s stop for a second to cover the definition of electronics manufacturing services, and what does it refer to.

Electronics Manufacturing Services (EMS) - Definition

Electronics Manufacturing Services (EMS) applies to the entire industry as well as to a specific class of subcontractors or companies. It is often used interchangeably with the term Contract Manufacturing Services (CMS) or Contract Electronics Manufacturing (CEM). Electronics Manufacturing companies provide a very broad range of manufacturing and accompanying services, such as supply chain management, engineering and product management support, as well as after sales support. Designed especially for OEMs, the services of EMS providers allow manufacturers to focus on their core business, i.e., product research and development, as well as sales and marketing of their devices.

Electronics Manufacturing Applications

From various industrial sectors up to the medical industry, more and more OEM’s are increasingly searching for electronic manufacturing services. Gone are the days when OEMs decided to work with a contractor for purely operational and strictly assembly-only reasons. Today, it is part of a well-thought-out overall business strategy.

Indeed, manufacturers have discovered that with a collaborative approach, they can achieve significant benefits that improve their customer service and quality of their products, as well as enable them to react faster to dynamic market changes. Thus, the total costs are reduced and OEMs achieve a value they would have a hard time to build on their own.

A few critical applications and their specifics that are worth having a glance at, are:

Medical devices: OEMs from the healthcare industry look at adequate certifications (ISO 13485), as well as tight process control and above average quality standards at the electronic manufacturing provider.

Industrial automation devices: a broad segment of devices that relate to industry-related devices, mainly used for control and automation of various processes. EMS providers supporting industrial electronics are required to be able to adequately manage high-mix low-volume production and support a variety of processes for OEMs (printed circuit board assembly, conformal coating, final assembly, electro-mechanical integration, testing).

What are the capabilities of Electronics Manufacturing Services providers?

One of the main services offered by the electronics manufacturing services providers is the Printed Circuit Board Assembly (PCBA) capabilities. Currently, the technological advancements allows a very fast and high-quality assembly, due to precise components placement capabilities. A sophisticated SMT assembly line is priced even on the level of millions of dollars, thus it may be an extremely high investment for an OEM. However, if they leverage the fact that the electronics manufacturers produce for a variety of Customers, they can gain access to a modern, fast, and flexible production lines for assembling complex electronic boards at a reasonable price.

Furthermore, many EMS companies provide assembly processes for combining printed circuit board assembly, together with cable harnesses assembly, box build or electro-mechanical assemblies along with the testing procedures. This provides the complete assembly services, where the OEM gets a complete offer and does not have to at all be involved in the production process at all.

The scope of services that electronic manufacturing services companies provide will vary one from another, depending on their strategy and capabilities. In summary, you can expect the following assembly services:

• PCB assembly (inc. SMT Assembly, THT Assembly and Conformal Coating)
• Box Build (including Potting)
• Electromechanical assembly (including Cabinet Assembly)
• End-of-Line Testing on finished Product
• Burn-in Testing at PCBA or Product level
