| Summary: | Strip testing is a semiconductor manufacturing process that performing electrical test while the device still in the lead frame strip. The device in the strip have to go through lead cut process for electrical isolation of the leads therefore we are able to perform individual devices test without affected/influence by other devices on the same strip. Strip test is a parallel testing of multiple units at the same time, increase throughput and reduce cycle time. Automation will replace the operator repetitive job and at the same time fully integrated with the manufacturing execution system. During change of lot, operator require to perform a series of system to physical validation and also many steps of system tracking in process before the lot started. Recipe are manually downloaded by the operator. Test program require manual triggering after the test order loaded into the tester. After processed, processed lot require operator attention in order to have the operator manually perform tracking out process then only manually moving out the lot to the next operation/process. By having all these manual key in, manual selection, manual loading, it consumed so much of productivity time and nevertheless by having human intervention it will increase the posibility of the quality issue. The objectives for the research are to investigate the current task at the strip test process.To develop an automation strategy at the trip test process. To validate the developed automation strategy. I will perform a detail study on current work mehtod, transaction and hardware then identify potential improvement area. Development and hardware upgrade to be carried out after identified the improvement area. By having automation functionality, we are expecting the gain of productivity and quality. Reduce the operator repetitive job and optimize the process can well be achieved by succeeding this research. Direct loading and unloading automation is the future of manufacturing without any human interaction, and this research is hoped to have a significant contribution and readiness for next level of automation. |
