Acceptable "reject rate" for hand assembly
What is an What is an acceptable "reject rate" for a total hand assembly, through hole operation line. I have established a less than .10% of all total hand placed through hole components for our load room.
We are a small low volume, high mix firm, using through hole boards, wave soldered. Is this a reasonable level to expect from our process?
