Whether you are looking to test the performance of an idea, evaluate room for product improvement, or showcase a new product to an investor or at a show, we will create an accurate and functional prototype representation of your PCB assembly design. 

Our goal is to solve your prototyping challenges by proving and testing your concept to help your customers/investors understand and visualize your product and then begin the manufacturing process. 


Prototyping allows you to test your PCB design and its performance before sending it into production. To ensure a high-end, functional product, PCBA prototyping is crucial and should be considered before full-service production. TJM Electronics will assemble your PCB to your specified design requirements then undertake comprehensive testing and evaluation. 

To prove exceptional performance, we will put your prototype through extensive testing to determine precise component placement, as well as environmental durability.

Putting a strong focus on quality assurance, apparent through our recent commitment to an AS9100D certified quality management system, TJM has the expertise and equipment to test your PCB design accurately.

Prototype PCB Assembly - microchip viewing-PCB


Specializing in prototype PCB assembly and small-volume production, we will explore your concept, uncover any design problems, and generate new ideas and opportunities for improvement to design for manufacturability (DFM). Prototyping gives you the ability to engage with your product, allowing you to see and fully understand its functionalities, as well as discover alternative solutions if needed.

1. Streamlined Manufacturing Process – prototyping eliminates the need for engineers to go through several iterations. By creating a prototype, you can get visual aid from clients, and discover design issues quickly, which will minimize the need for rework in the long run and allow your team to have a thoroughly tested and secure PCB assembly before production.

2. Reliable Prototype = Reliable Product – Having a reliable prototype will allow you to test the PCB assembly design, functionality, and environmental resistance that will reflect on the final product.

3. Reduces Overall Cost – Prototyping allows designers to see the ins and outs of the PCB design and functionalities, allowing them to catch any faults in the design and fix them before investing in a full production run. This will ultimately save time and money in the long run and mitigate the risk of rework, or even worse, a complete product redesign.


At TJM Electronics, we understand the various reasons for creating a prototype of your PCB assembly and want to see our customers satisfied with their overall product. We are experts at what we do and will go above and beyond to ensure high-performance electronic prototyping and comprehensive testing so that your product is safe, manufacturable, and ready to go to market.
