Alot of QM's and QE's are typically failed Engineers who lack common sense. They don't understand that measuring in DPMO's (versus DPU's) "normalizes" your data for Printed Circuit Board Assemblies (PCBA's) so that if you have 10 defects on a PCBA t

Hi Michael, DPMO Index calculation - The total number of defects (Dc + Dp + Dt) on a completed Printed Circuit Board divided by the total number of defect opportunities (Oc + Op + Ot) for that PBA multiplied by 1 million. Your calculation deals only

99% good solder joints = 10000 ppm (defects per million opportunities). Having only built with 0603s I can't speak for a target but that still seems pretty harsh....with a 75/25 0805/0603 ratio at my last place of employment I think we were running

Have you thought about an AOI system? With the system we have where I work, I'm able to run queries that'll tell me DPMO, yield, and pass/fail rates on a board level, part level, and opportunity level. Furthermore, this data can be broken down to see
