Because of the slight differences, like test voltages, between the two
specifications the only way to cover both is to test for both.

Subject: [IPC-600-6012] Table 4-4 -vs- MIL-PRF-55110 table A-V

I am curious to know if IPC (or members of this subcommittee) has on
opinion
on quality conformance testing differences between IPC-6012 table 4-4
and
MIL-PRF-55110 table A-V (group B).



Historically I have used the group B results as compliance to table 4-4
and
know many other companies apply this practice also. To date it has not
been
a problem but I now have a situation where one customer is not accepting
group B results due to higher voltage during MIR/DWV testing and
MIL-PRF-55110 allows delamination (within limits, although the test
results
state no delamination present) and table 4-4 (or IPC-6012) does not
allow
delamination.



So.I was hoping to gain others (including IPC representatives)
perspective
and/or opinion.



Thanks,



Franklin D Asbell
