Can you guys give me a heads up on "Traceability". I find it to be a stumbling block in my process and delays my manufacturing throughput big time. I wanna have a clear understanding of when you need it, why you need it and how will you benefit from it. This is one of my issues here:
Any rework done on my PWB (let's say solder joint issue) must be documented and a rework traveller is being raise to be able to execute a rework job on that certain solder joint. This needs to be signed by Mfg. Supervisor, QC etc. Another thing is that any program changes in my SMT machines must have a rework traveller done. I can't touch the machine at this point.
Your company has chosen to define its requirements for tracebility as it has. So, people there should be able to help you understand their purpose and intent.
For instance: * We distinguish between 'repair' and 'rework'. Repair requires a MRB action. Rework does not. * For us, machine programs as work instructions that can be revised locally [with supervisor by-off]. If a work instruction is revised, the work instruction get rev'd, as does the traveler. [See for a contractor, like you, probably every lot that you run on a board is different. So, you're at rev AAAA very quickly.]
