First Pass Yield Optimization

First pass yield losses of 10-15% of revenue are common across discrete and process manufacturing, yet the drivers of rework and scrap are rarely well-understood at a granular level. Quality systems capture rejection codes but do not automatically correlate them to the upstream process parameters, raw material batches, or environmental conditions that caused the failure, leaving engineers without actionable insight into where to focus improvement efforts.

Where are we losing the most first pass yield, and why?

Product Family C has the lowest FPY at 86% and the highest rework cost on the line, and 70% of its rejections tie back to cure-oven dwell time falling below the golden-batch window of 92 to 96 seconds. Hold dwell time inside that window and you recover roughly 7 FPY points worth about $340K per quarter.
