Repeatability is the requirement
Medical customers rarely ask for something exotic. They ask that the thousandth assembly be indistinguishable from the first, that any change be documented, and that records exist if a question comes up two years later.
That is a process problem, so we solve it with process: documented work instructions, calibrated tooling with crimp validation, inspection against IPC/WHMA-A-620, and 100% electrical test with retained records.
