Abstract

This paper presents a case study that a PCB company applies DMAIC-based Six Sigma methodology to improve product yield and to reduce discarding cost. According to the analysis, the inner layer open is one of the reasons that results in PCBs defect units in this case. After improving the manufacturing process, the PCBs defect units were successfully reduced from 82,100 to 69,700 defects per million, generating a cost savings of US1.41 million.
