OK, for ANYONE operating in the hi-rel industry, it is widely known and accepted that assemblies may be reworked without customer approval, but all repairs require customer approval. Some customers / programs do not even grant any MRB authority to the vendor. Now, my company is an OEM. We are not a contract MFR. However, we had a case of a PCB with a via that was non-functional. A tech wanted to just install a short jumper through the via to re-establish the connection. Myself and another tech argued this was a REPAIR and as such required customer approval. The tech in favor of the jumper argues that jumpers are covered by 610, and therefore allowed. My rebuttal to this was jumpers are covered not as an implication they are ok in a repair situation, but to give guidance as to how they should be made if part of original design intent or part of an authorized repair. He is now vehemently arguing that unless I can show him where in any IPC standard it says repair requires customer approval, then I am wrong. Alas, I cannot find it. Does such a statement exist? My suspicion is that the answer lies in the contract paperwork for the part, not an IPC document, but if anyone knows it does exist, and can point me to it, I would be MOST appreciative..
