A top company will likely have complete and advanced equipment and ISO 9001 certification for its quality management system. These certifications act as beacons of expertise. If you’re unsure how to choose a PCB assembly service provider, consider getting a quote from one and comparing it with the prices offered by different suppliers.

Prototype assembly is an essential part of the printed circuit board manufacturing process. It can help you determine how well your design will function at high volume. Furthermore, it can reveal potential pitfalls, such as errors and bugs. It’s, therefore, ideal for learning more about prototyping PCB assembly services before choosing a provider.

What to Look for When Choosing Prototype PCB Assembly services

When choosing a PCB assembly provider, you should consider the manufacturer’s quality, process, and experience. PCB certification is a good sign of quality control procedures, while experience indicates how long the supplier has been in business. Usually, suppliers with more experience tend to have higher quality standards and know the best ways to handle prototype PCB assembly.

You can find PCB assembly services to build your PCBs. They can also manufacture your PCBs from a kit of parts in as little as 24 hours. However, you should be careful when choosing such services. Here are a few things to remember: Costs, Tests, Reliability, and Quality.

Cost of prototyping

When you need PCB assembly services, you must know what to expect. Prototype PCB assembly services can provide the PCB components you need to make your product work. A PCB assembly company can help you with all the PCB components you need, from the design stage through the assembly process. The PCB assembly process will include constructing the PCB board thickness and any necessary solder paste. It will also include the assembly of the prototype printed circuit boards.

PCB assembly costs depend on several factors, including labor rates and overhead expenses. While the average cost of a prototype PCB assembly service is $0.02 to 0.05 per square inch, prices can vary significantly. It’s also important to remember that your design’s complexity will affect the PCB assembly process cost. For instance, a more complex design will require more time and labor than a simple one.

Prototype PCB assembly involves assembling various prototype boards and components to make a functional prototype. This requires a special board arrangement, SMD parts placement, and soldering. The prototype must meet the functional requirements before moving to the final product manufacturing stage.

Experience level

The experience level of a PCB assembly manufacturer is an essential factor when choosing a supplier. An experienced PCB manufacturer will have the ability to produce your prototype PCBs in a shorter period. They should also be capable of delivering a quality end product. Finally, they should be able to provide you with a detailed quote for the first PCB assembly order.

A PCB assembly manufacturer should have a proven track record. They should be able to offer you the latest manufacturing techniques and equipment. They should also be able to work through any problems or challenges and provide solutions. This way, you can be sure that your PCB prototype will meet your expectations.

The company’s feel can judge the experience level of a PCB assembly manufacturer. If it feels professional, it is likely to be a top-level supplier. For instance, if the company is overly formal, you may have difficulty working with them.


There are several aspects to consider when choosing a PCB assembly order. First, the quality of the assembled PCB is essential. A defective PCB board will lead to a malfunctioning product. Another critical factor to consider is the knowledge of the service provider. A reliable service provider should have information about quality standards on their website. They should also have reviews of their customers that you can check. Positive customer feedback shows that the company offers quality prototype PCB assembly services.

Prototype PCB assembly is a complex process. It requires experienced engineers to produce high-quality prototypes. In addition, the service provider must source PCB components within its premises. Outsourced PCB components may compromise the prototype’s design.


One of the essential factors in choosing a prototype PCB assembly service is the reliability of the work performed. Unlike a low-cost DIY service, a high-quality prototype assembly service should provide the highest-quality assembly possible for a reasonable price. Production PCB assembly starts with the preparation of the parts, which typically includes the bare PCB, IPQC-passed parts, stencil, and SMT machine set-up. The whole process can take 10-14 days. However, the turnkey service may be completed in less time if no errors occur during the process.

PCB assembly services are an excellent way to test and identify a circuit before finalizing it in mass production. The process is standardized, so replacing faulty components and fixing errors early is easy. PCB assembly services will also provide various test options for the circuit.

Processes involved in prototyping

Prototyping PCB assembly is a process where we implement a new printed circuit board design into a final PCB. In most companies, PCB prototyping is a standard procedure. The goal of PCB prototyping is to maximize yield and reduce costs. Once the design is complete, the production process can begin.

Prototyping PCB assembly starts with the design phase. In this stage, engineers research the application and develop a prototype design that will work for the new application. It must be accurate and efficient while using the least resources possible.

The next stage in the prototyping PCB assembly process is the placement of components. First, we plate the board with a copper layer, either a copper coating or a copper foil. The copper is then covered with a solder mask to prevent short-circuiting. The final assembly step includes placing the final small components, soldering electrical connections, and removing any excess flux. New technologies allow assembly companies to remove solder paste without using chemicals.

Experience level of customer support

When choosing a prototype PCB assembly provider, it is essential to consider the company’s experience. A company with a high level of experience can handle a more complex project in a shorter amount of time. They should also be capable of handling mixed technologies, including through-hole and surface-mount technology.

An experienced production PCB assembly provider will have advanced equipment and management systems and a highly trained and knowledgeable workforce. Moreover, they will have a certificate of ISO 9001 quality management system, which indicates their expertise.

A PCB prototype assembly provider should have a high engineering experience and source PCB parts from in-house vendors. Outsourced components could compromise your prototype plans.

Rigid Flex Prototype PCB Fabrication

This section will discuss designing a rigid-flex prototype PCB and preparing it for fabrication. We will cover the base material, through-hole plating, and testing. These steps are essential for creating a rigid-flex prototype PCB that works flawlessly.

Designing a rigid-flex PCB

When your design is more flexible than traditional printed circuit boards, you may want to consider using a rigid-flex prototype. These boards are often made of two separate parts but can be designed together in one process. We can create Rigid-flex PCBs in hours rather than days, with several features making them an excellent choice for prototype PCBs.

When designing a rigid-flex PCB, be sure to take into account the physical properties of the circuit. You should use an accurate trace width calculator to determine the proper size of traces and components. Ensure the circuit space has enough room for the different components and pads. You should also use large annular rings and solder pads to keep the PCB fabrication rigid.

When choosing a material for your rigid-flex prototype PCB, remember that it must be resistant to damage during use or handling. Many different materials are available for flex PCBs, and the choice depends on the device and application type. One option is using woven fiberglass or epoxy resin as the substrate. While these materials are durable, they aren’t as reliable as polyimide.

Preparing the base material

When manufacturing a rigid-flex PCB, the base material is critical. For example, we should plate copper in the appropriate locations, and the material should be of the appropriate thickness for the circuit design. We prepare the base material with an acidic solution and carefully scrub the copper layers to remove adhesive coatings. Once this step is complete, we deposit the copper into the holes. The copper is then chemically plated to create the required electrical interconnections.

Once the rigid-flex printed circuit board is complete, it must pass quality, electrical, and circuit performance testing. The final tests must verify that the circuit performs as designed and is safe for use. Several testing methods exist, such as the grid test method and the flying probe method.

Through-hole plating

Through-hole plating is a process that allows the creation of custom rigid flex prototype printed circuit boards. We perform it using a high-speed drilling machine. The process often combines with laser drilling, which makes it possible to create precision holes with an extremely high level of accuracy.

Rigid-flex PCB fabrication can be difficult due to the thickness required to accommodate the board. This may hinder miniaturization efforts and lead to inefficiencies during manufacturing. In addition, the quality and ease of the process depend on the materials used to produce the circuit boards. For example, different materials have different thermal expansion coefficients, which can affect the adhesion of the layers to one another.

Through-hole plating is essential when using rigid-flex PCBs because it can help reduce the stress placed on the pads and components during the bending process. In addition to through-hole plating, flex PCB fabrication can also include additional coverlay to support the components.

Testing printed circuit boards

Rigid-flex PCB prototypes can be helpful for design verification, functional testing, and short-run production. In addition, this type of PCB fabrication is cost-effective and allows manufacturers to source a PCB prototype at a lower cost than if they were to create the printed circuit board from scratch.

Rigid-flex PCB fabrication involves a series of processes that ensure the board is as precise as possible. First, we treat copper to provide oxidation resistance. Then, after plating the copper, PCB manufacturing companies can use high-speed drills and lasers to drill precise holes.

Rigid-flex PCB fabrication is cost-effective and ideal for high-density applications. The reduced size of these boards allows them to incorporate more components in a small space. They also require fewer interconnects and can be made to withstand harsh environments. Lastly, they are easy to test, making them a perfect option for prototyping.

The main difference between rigid and flexible PCBs is their amount of space. A rigid PCB needs a specific space to function properly. In addition, it is also susceptible to breakage. Because of this, rigid PCBs are not ideal for compact devices. In the past, rigid printed circuit boards were the norm. But today, rigid-flex PCBs are an excellent choice for many industries.
