Prototype PCB Supplier Selection Made Easy: A Step-by-Step Guide

Prototype PCB Supplier Selection

Finding a suitable prototype PCB supplier that fits your business is crucial for success. Suppliers play a pivotal role in making an organization successfully deliver services or products to its customers. Organizations’ raw materials to create the final product are often sourced from suppliers.

PCB suppliers are a vital aspect of a manufacturer’s supply chain management to deliver the final product to the customers. Suppliers can help increase the number of happy customers. They can ensure the availability of PCBs needed for your product, which can reduce any delays in meeting your customers’ orders. For example, if you can produce and send a product to a customer in 7 days rather than the usual 30 days, it trims down the waiting time of your customers, which in turn allows you to serve more customers.

Suppliers play a pivotal role in making a manufacturer successfully deliver services or products to its customers. Usually, circuit boards needed to create the final product are sourced from suppliers.

What Is PCB Prototyping

One crucial aspect of producing circuit boards is PCB prototyping. Prototyping is wider than PCB manufacturing since developing a prototype before being mass-produced is common in other industries like automotive manufacturing.

What is PCB prototyping? It is building an early version of PCB patterned on your design. It is the first functional model of a PCB design, which is intended to assess the functionality.

Prototype PCB supplier creates an early version of the circuit board based on your specifications as part of the pre-production process to check the loopholes in the newly designed circuit board.

Why Do You Need PCB Prototyping?

PCB prototyping is an essential process in circuit board manufacturing since it is vital to put the initial version under trial to discover what is working and what is not.

Solve design issues

Prototypes are the tangible version of a PCB design. Usually, a prototype PCB supplier starts developing a new circuit board by designing it first in computers. A supplier will run a computer simulation on the new PCB design to see how it works virtually. However, you still need to build an initial version of the circuit board to see how it will function.

A PCB prototype allows designers to assess the accuracy of the design. They can check design flaws and issues, which they can resolve and correct before they go on to mass-producing the PCB. It is more economical to build several prototypes to test the design and address the issues after you mass-produce it and correct them in all the assembled circuit boards.

Check functionalities

A good PCB design is only sometimes guaranteed to work in practice. With the help of a prototype PCB, designers can check if what works in their design works in practice. If it does not work, they can determine the differences, make the necessary adjustments, and reevaluate the design, especially functionalities that are significant to a circuit board.

Designers can also assess if their PCB design would function accordingly in the real world. Would it still work well under varying temperatures and other environmental conditions? For example, PCBs used in aircraft should withstand harsh atmospheric conditions. A prototype PCB supplier needs to test PCB design PCB for aeroplanes to see if it can be fully unexposed while exposed to extreme conditions in the upper atmosphere.

Step-by-Step Selection Guide

Finding the proper prototype PCB supplier for your business might be challenging. There are so many prototype PCB suppliers out there. Here are six steps that can serve as your guide in picking the prototype PCB supplier suited for your business:

Check the experience

One of the most essential factors you should consider in picking the proper prototype PCB supplier for you is experience. It would help if you choose a supplier with a proven track record in designing a PCB and building a prototype PCB. As has been repeatedly said, “Experience is the best teacher.” A prototype PCB supplier with a lot of experience designing and producing PCBs can make the circuit board you need and provide suggestions and insights into your PCB design.

However, you should also note that the prototype PCB supplier’s experience and expertise must match your project’s requirements. For example, suppose you are looking for a supplier who can do surface-mount technology,y. In that case, the supplier should have experience and expertise in surface-mount technology regarding PCB assembly.

It is also good to know what industries the potential suppliers have worked with in the past and if they have worked on projects similar to yours. Familiarity with the industry that you belong to and the project would result in a more fruitful engagement.

Ask for the cost

In most cases, the cost is the most critical factor if you engage a potential prototype PCB supplier. This is understandable since many businesses operate on limited resources. You must complete the project within a specific budget since your project is not one of many projects taken in your organization.

Like any other business, the mindset is to get the best value at the lowest possible cost. Hence, most often, cost becomes a deal-breaker in negotiation. You can obtain cost quotations from multiple potential suppliers and compare them. The number of orders influences the PCB assembly process’s cost. You could take advantage of bulk orders for a much lower price for each unit.

The required services are also drivers of cost because the cost for the surface-mount technology process is different from the through-hole process. If you require the supplier to do more testing for the prototype, they can charge you more for each extra test. The materials and components you will need to build the circuit board impact how much they will charge you.

Discuss delivery time

Check if a potential prototype PCB supplier can deliver the circuit boards on time. Any delay in PCB delivery could also affect the timeline for the production of the final products and the delivery to customers. You can do a background check with previous companies they have engaged with to inquire if they could meet the deadline. If previously, they had a higher percentage of failing to meet the agreed timeline with other clients, that could be a red flag.

It is important to note that you also have a timeline for delivering customers’ orders as a business owner. If your prototype PCB supplier fails to meet the agreed deadline, you will more likely miss the timeframe for possible mass production of the circuit board and have a PCB shortage. If there is a shortage of circuit boards, it would definitely disrupt your supply chain and, worse, could halt your operation.

Provide customer support

Regular communication is valuable for a good working relationship with PCB suppliers. You can check if the supplier has customer support to communicate consistently with their clients. Maintaining communication channels between you and the prototype PCB supplier is crucial. How responsive is the supplier to your inquiries? Can they address your concerns immediately? It would be better if a dedicated account management team directly handles their engagement with you. Determining if the supplier is amenable to regular meet-ups with you is also helpful in tracking the project’s progress.


Selecting the proper prototype PCB supplier is one of the most crucial decisions you must make as a business owner. Creating a PCB prototype is essential before you can mass-produce your new circuit boards.

When choosing a suitable supplier, you need to check the supplier’s experience in making PCB and whether their asking price is within your budget. The supplier’s ability to deliver the prototype on time is significant to your production. Keeping communication channels open between you and the supplier would lead to a better working relationship.
