Abstract
The statistical process control (SPC) of destructive pull test on 1 Au gold wire is studied on two high-rel devices, namely #1 and #2. It was found that the Cpk of both parts are around 1.2, which have not meet our goal of 1.33 and the ultimately six sigma (Cpk= 2). However, this study shows that the traditional method of calculating Cpk has underestimated the capability of process control if considering the tolerance as asymmetric, such as the case for 1 mil gold wire bond.
