Jim,
Before I get into trouble, Jim, my answer to your question is: we use
IPC-STD-001. Now... to get into trouble...
What is the problem with '001? OK, I might have the problem. I THOUGHT
that IPC-A-610 was the picture book for the workmanship requirements
(words) in J-STD-001. Isn't that what the table in the inside cover of
J-STD-001 is meant to convey?
So why would someone call out IPC-A-610, when J-STD-001 already does it
for you? I know it is a common practice, but have never understood it,
even for commercial work.
For example, if one called out IPC-A-610 only, it might be acceptable to
inspect the solder joints looking through a microscope backwards, to a
15% AQL level.
HEY, IPC... Was the '610 intended to be used as a stand alone?
Or was it established for the 'reading impaired' who could not
understand 'J-STD-001?
There, that should insult enough people to provide me a broad education
on the subject by the time you guys get done flaming me! Thank you for
the barbecue. I'll get the sauce. Learning can be painful, but always
worth the trouble.
