Hello technet gurus,
I have a question regarding total copper thickness for external conductors.
3.6.2.13 states only a requirement for total conductor thickness, that is foil + plating, and references table 3-12 for the appropriate values. There is no requirement for the foil thickness.
Table 3-12 also has a column with heading:
Absolute Cu Min. (IPC-4562 less 10% reduction)
Does that column heading constitute a requirement? Would using a copper foil less than the stated minimum constitute a rejectable condition even if total copper thickness meets requirements?
Engineering states that they only care about the total thickness from a functional point of view.
I ask this because I have a difference of opinion with a colleague on the interpretation of the standard.
Best regards,
Raye Rivera
