Abstract
This research aims to reduce waste in the printed circuit board manufacturing process by applying seven quality tools. Due to problems with the waste in the printed circuit board manufacturing process. The waste is characterized by the carrier assembled with the printed circuit board being scratched. Therefore, the cause of the problem is analyzed with a cause-and-effect diagram and analyzed the root cause of the problem with the “Why Why analysis” questioning technique. The main cause that can be solved immediately is the cause of the machine that the printed circuit board was exposed to the programmer while testing the board printed circuit. Because many printed circuit boards is inserted at the same time, causing the carrier to scratch. Therefore, it has been modified by designing and building the back hips sheet to prevent scratches and can be used with the program to test the use of printed circuit boards appropriately. After the improvements, it was found that the original waste was 13.45% of the amount produced, reduced to 0.18 percent of the amount produced.
