Standard PCB Board Specifications VS. Custom PCB Board Specifications Whether you have a need for a double sided or a multi layer PCB, Wonderful PCB is your one stop printed circuit board provider. Deciding whether you need to order your printed circuit board as a Standard Spec or as a Custom Spec board is simply a matter of looking at the specs. Standard Spec boards (PCBs) are inspected to IPC Class 2 Standards and Custom Spec Boards are inspected to either IPC Class 2 or Class 3 depending on what option is chosen.

Quantity doesn’t matter. We don’t have MOQ, No order is too small for us! Quality is the same. All Standard Spec and Custom orders go through the same rigorous fabrication and quality check process.
