Nowadays,semiconductor manufacturing companies aim for higher productivity with short lead time that will maximize the profit to the organization for their survival. This project is conducted at Infineon Technologies(M)Sdn.Bhd. especially at Front of Line area that focusing on quality performance of visual inspection for die bond and wire bond processes. There are redundant quality visual inspection activities between Production operators and Process Control operators.Here, the production operators whom operate the machines while Process Control operators whom conducting quality surveillance checks perform similar quality visual inspection.
