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 ?

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.

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 ?
