PCB Prototype

Prototype PCB Specification

Are you in the process of developing a new printed circuit board-based solution for your company? This can be an extremely time-consuming, labor-intensive process where there is a high degree of uncertainty in the outcome. Developing a PCB prototype offers a fast, cost-effective option for getting your design from concept to production, while minimizing some of the risks associated with a standard PCB service.

Prototype Printed Circuit Boards That Meet Our High Quality Standards

PCBCart is able to offer rapid PCB prototyping services at a low cost yet with very good quality. We're fully compliant with ISO9001:2008 quality management systems, and we have an in-house quality control department to verify that all work meets our high standards. In fact, we adhere to the same stringent quality control guidelines for PCB prototyping as with our standard PCB production to guarantee the prototype board quality.

What Are the Benefits of Circuit Board Prototyping?

We recommend using our PCB prototyping service for function testing of new products prior to making a commitment to a full-production run. Benefits of developing a printed circuit board prototype include:

• Ability to rapidly test and correct designs so you can hone in on the finished design more quickly

• Quick turnaround time helps you achieve your productivity goals

• Opportunity to detect potential design flaws in the early stages

• Low-quantity production runs featuring a minimum order quantity of only five circuit boards

• Lower production tolerances provide a clear indication of how well the finished product will ultimately perform

Once your proto boards have been fully tested and demonstrated their ability to meet your quality and performance requirements, it is ready for a full production run. At this point we will transition to our standard PCB service, as this provides tighter production tolerances than PCB prototyping. You will also have the ability to implement larger/more challenging PCB designs if applicable. Our standard PCB service includes the use of technologically advanced Design for Manufacture (DFM) software that allows us to detect any potential issues that could reduce the quality of your PCB.
