Rigid Printed Circuit Board

What’s the Difference Between Standard Spec. vs. Custom Spec.?

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 are built to the same standards as Custom Spec orders but with a more limited spec range. Standard Spec and Custom Spec orders are inspected to IPC Class II Standards.

Turnaround time is the same. We can produce your Custom Spec order just as quickly as our Standard Specs orders even creating them in one day if needed.
