Abstract :
In 2005 , PSG1 SOT54 Glue line generated 2 cases of justified "bond off" customer complaints from BT169 product. We have defined several improvement actions in our 8D reports, but was unable to come up with an effective real-time monitoring on "bond off" defect. In line with Philips Semiconductors\´ Zero Defect Quality Improvement Initiative, by working closely with our wire bonder manufacturer, ITEC, we acquired 12 sets of "bond-off" detector kits in mid-2005. However, they failed to effectively monitor this defect despite after 6 months of troubleshooting by ITEC experts.
