Hi! As a contract manufacturer we have to deal with various products designed with different CAD programs. Due to this fact we are not able to generate all the data we need for preparation of the PCB (SMD) assembling - e.g. Pick&Place file. We receive from the customers BOM and mounting plan they are convinced that should do (many of the don't have previous experience with automatic assembling). We ask the customer to submit the Pick&Place file and ... there comes the problem - the data are not always correct. There were lots of cases when some components value in P&P differs from the ones in BOM and even there are wrong reference positions. Since we are not being informed about that, we usually find out about the difference at the P&P equipment programming stage. Due to that we were forced either to perform false/true check of both P&P and BOM files or even component by component manual check BOM>mounting plan>P&P file. My questions are: 1. Based on the good practice is it appropriate to insist for complete, correct and checked P&P (and all other data) files? 2. Who is expected to be responsible for any mismatch in the documentation? Any opinions are greatly appreciated!
