Louis,
Thanks for the answer but when you say :
"Customers who want either the checklist or microsection report are welcome
to have them. "
If the manufacturer answers "we are certified for class 3 production, we
don't have to store the test reports", what can I answer ? Does the IPC
specify anything about test reports traceability and theirs storage ?
Thank you

Objet : Re: [TN] Class 2/3 test report traceability
Look at Table 4-3 of IPC-6012 to see what inspections are to be performed.
We have a checklist summarizing all attribute and variables testing for each
job. Not all boards or panels are tested, for example, for solderability or
for bow and twist. Table 4-2, as referenced by Table 4-3, define the number
to be tested.
Further, we prepare a microsection report for panels, inspected as described
in Table 4-3. Class 3 multilayers get (based on our lot size) 100%
microsection. Class 2 two-layer panels get sampled. (If one of the
two-layer samples fails, the remainder are microsectioned.)
Customers who want either the checklist or microsection report are welcome
to have them.

Subject: [TN] Class 2/3 test report traceability
Dear all,
We have purchased a class 3 PCB and I want to check that all the tests
required by the IPC 6012 have been performed.
The traceability chapter of the IPC 6012 isn't really clear : does the
manufacturer must store the test report of each board/panel ? Can I required
him to send me those test reports ?
If the answer is "no", how can I be sure that my PCB is conform to a class 3
specifications ?
Regards,
