The PCB Norsemen: Avoid Failures
in PCB Production With
Compliance Control E
Failures and reliability in the
printed circuit industry are
usually considered in the
context of quality claims and
non-conformity. This is a logi-
cal approach; however, there
is a new context where these aspects are under
close scrutiny, namely compliance—especially
in the defense industry.

Testing Todd: What Do You Mean
'Passed' Isn't Enough? E
From a reliability standpoint,
we need to quickly assess
what risk we may have un-
covered when faults are de-
tected during electrical test
(ET). "Passed" is not always
passed. We must be diligent to scrutinize the
failures found during routine ET as a high yield
may not indicate high reliability.
