Increase in Production Due to First Pass Yield Improvements

Abstract

First Pass Yield (FPY) is a critical quality indicator at the electrical sector, dedicated to the manufacture of industrial breakers, and its improvement can have a significant impact on operational efficiency and customer satisfaction. In this project, the DMAIC (Define, Measure, Analyze, Improve, Control) methodology was used to address and reduce the quality problems found in the FPY analysis. The specific quality problems that affected the FPY were identified through exhaustive data and other relevant quality indicators on the breaker production line that were collected. Also, critical measurement points and variability evaluation in production were included. To identify the root causes of quality problems affecting FPY, manufacturing processes were examined in detail. Then, effective solutions like optimizing processes, improving staff training, updating equipment, and reviewing material specifications to ensure product quality were implemented. Finally measures were established to guarantee that the mprovements implemented are sustainable in the long term; tracking and monitoring systems implemented to verify the effectiveness of the solutions; and corrective action plans developed to address deviations in the FPY.
