It involves the removal of cutter blade used for derail.Cost improvement was one of organizational goals of the company for 2019. This drive can be supported by analyzing Indirect Material spending and process simplification at assembly plant. At assembly End-Of-Line processes, derail cutter blade was one of the top Indirect Material spending at singulation and there is an opportunity to reduce if not eliminated the cost consumption of derail cutter blades through process simplification. Increasing volume in Quad-Flat-No lead (QFN) packages and new banner products being develop by New Product Integration <em>NPI</em>, Q1’20 means increase in IDM consumption per process. The challenge is to drive a process simplification that will reduce IDM to save cost by start of Q2’20. DMAIC methodology was used to improve the process of derailing process.</p> Christopher L.

This paper is focused on the improvement done for QFN leadframe device to address the major machine assist during the lot processing at wirebond process. Illumination and visual of the leadframe and the sand blasting process plate on the machine are difficult to separately distinguish due to similar color shade of the materials, thus frequent machine assists ensued. To reduce the frequent machine assist occurrence, an improvement is done through enhancing the process plate by using a black chrome to totally separate the illumination of leadframe and the process plate. Ultimately, the machine assist during wirebonding process is improved (the longer the better) from 16 minutes to 6 hours continuous and uninterrupted running.</p> Jonathan Pulido Edwin Graycochea Jr. Frederick Ray Gomez ##submission.copyrightStatement## 2021-04-12 2021-04-12 13 16 10.9734/jerr/2021/v20i517306
