PCB Capabilities

In the table below is a key PCB capability list of NextPCB’s printed circuit board manufacturing. This table is designed to help you understand if our capabilities are a match for your design. It will also allow you to plan ahead and create your design within these capabilities so that you can be sure we can produce your PCB.
