This is a common problem with customer supplied parts. The customer wants you
to be perfect, no losses. They can't do it but they want us to. Keep trying.
I am working on several jobs right now that are customer supplied material.
In some cases they have sent unusable pieces of taped parts, too short for
the p&p or no leader. We have managed to convince some of them to send the
reels of parts and we send the residual back to them with the product. I
think this is the best solution for both of us. Funny? thing is that usually
it is the cheap parts that we are short. Just did a job for 12 boards that
had 6 extra  $1200 parts but exact qty. of 0603 caps at 1.3 cents ea.

Hi Technetters!

We assemble PCB with all components supplied by the customer. It is very
often we have to struggle on convincing customers we need a small reserve of
components (up to 5%) due to Pick and Place equipment reject rate and other
occurrences. Failing to do so leads to unfinished boards and pile of records
and reports according to ISO 9001-2000 QS. I have a kind request if anyone
could share their experience with this issue! And yet is there a certain
regulation applicable to Contract Manufacturers&customer obligations in that
case?

Thank you in advance for all inputs,
Happy Easter to all!

Best regards,
Yordan Venev
Manufacturing Manager
