Hi team - Just a point of clarification as I see this point pop up with some frequency. The requirements for a printed circuit assembly are in the
IPC-JSTD-001 specification and the Workmanship Criteria reflecting those requirement as in the IPC-A-610.  I know if sounds mundane and lots of folks typically cite the 610 specification as the "requirements"  since that is what the operators/auditors have in their hands but using specific document clarity is important in our industry. We have tons of requirements and criteria so citing 001/610 correctly and as a set can be super beneficial for everyone. Sorry for the soapbox, just trying to be positive and proactive.
