Abstract

In the competition to excel in the Industrial 4.0 race, companies especially in Semiconductor Industry, strive to attain efficiency by removing process bottlenecks, improving productivity and increasing machine availability during operation. As so, this research was conducted to analyze the machine’s availability based on various preventive maintenance (PM) scheduling. A model was developed in WITNESS 14 Manufacturing Performance Edition software to imitate the Surface-mount Technology (SMT) line in a manufacturing system. The model was build based on a serial layout of five machines which are a screen printer, glue dispenser, chip shooter, pick and place and reflow oven. Then, the simulation was run to study the availability of each machine with relation to different stoppages intervals and duration based on the selected PM schedule. The findings of this project show that PM for an SMT line should be carried out every week with 30 minutes PM duration to achieve high machine availability and minimal machine downtime.
