Analaysis of Additional Sensor Detection for Product in Underfill Machine

Abstract

Company XYZ conducted this study by adding additional sensors to the underfill machine. This was done to facilitate the identification of defective products and reduce the number of non conforming (NG) items. The detection sensors were designed to detect defects in FPC products, making the resin application process easier with the sensors in place. As a result, the rework typically performed on defective products is now less necessary. The cutting and splicing process requires manual visual inspection, which causes delays and downtime in the next step, namely the M-Test machine. The objective of this study is to analyze the root causes of non conforming products on the underfill machine and to determine appropriate corrective and preventive actions to minimize product rejection. This study includes process flow analysis, checklist verification, and the development of a plan for the installation and control of equipment, materials, and work methods. The addition of extra sensors is expected to improve the effectiveness of the underfill process, reduce the number of rejected products, and minimize downtime on subsequent machines.
