That is the purpose of a thorough process/procedures audit done
periodically to ensure the material received is going to be good.

Hi,

I guess we have a good idea now of the difficulties in specifying and
manufacturing lead-free capable PCBs. The next question that comes to my
mind is how are we going to assess if the PCBs that are well speced are
what we expect?

I mean, the spec can be OK, whether perfect IPC-4010 slash sheets are
developed, or STII is implanted. But the manufacturer might still use
expired prepregs, they can have lamination problems, and so on.

What tests shall a contract manufacturer or OEM with no in-house testing
capability impose, in order to have the confidence that they receive
what they specified?

Thanks,

Ioan
