1) IPC-6012 / IPC-600. Is acceptability per IPC-A-600 implicit in IPC-6012? Our PCB drawings have notes stating fabrication per 6012, acceptability per 600. The vendor is stating IPC-600 is implicit in 6012. I see the logic, and even agree, but no-where in 6012 (that I could locate), except "Reference Documents" is there mention of 600. 600 has a nice statement in section 1.5 stating "IPC-6010 series establishes the minimum acceptability requirements for printed boards. This document, IPC-A-600, is a companion and complementary document, providing pictorial interpretation of these requirements." So I have a link from 600 to 6010 series, but nothing from 6010 series to 600. ??? 2) IPC-6012, Section 3.8.2. "Electrical Continuity and Insulation Resistance". First sentence states "Boards shall be tested in accordance with IPC-9252, IPC-9252 ""Guidelines and Requirements for Electrical Testing of Unpopulated Printed Boards." does not use the term "Insulation Resistance" anywhere. They define "isolation resistance" (sect 3.21) and define an "Isolation Test" method (sect 4.2). I am not an expert in test, particularly around bare PCBs (vs populated pcbs), but I had always understood isolation to mean something completely different than insulation resistance. Is this correct? Is the 6012 reference to "Insulation" resistance in error? II would be particulary interested in getting some test basics from someone, offline even if required.
