PCB Prototype

Prototype PCB Specification

In the process of developing a 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 offers rapid PCB prototyping services in very good qualit yet at a low cost. 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. Depending on your custom requirements, we can prototype your PCB within 3-7 days, compared to 6-18 days of Standard PCB service. The following articles give you enough info about our Prototype PCB and Standard PCB services and their differences:

What Are the Benefits of Circuit Board Prototyping?

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

• Rapidly test and correct designs if there is any mistake

• Opportunity to detect potential design flaws in the early stages

• Quick turnaround time helps you achieve your productivity goals

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

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


Once your proto boards demonstrated their ability to meet your quality and performance requirements, it is ready for a full production run. Then we will transition to Standard PCB service. It provides tighter production tolerances and more advanced options includeing free Design for Manufacture (DFM) check that is capable of detecting potential issues which could reduce the quality of your PCB.
