| Abstract: | Due to PTFE materials＇ inherent characteristics, it＇s facing many technical bottlenecks at manufacturing, especially reflected in the design process about ＇pure PTFE multilayer ＋ step groove＇. This paper discusses the PTFE step board＇s process design and laminating control technology. Through synchronous etching and quickly laminating plus lid removing process by depth milling control, it effectively solved the technical problems about low adhesion and pads deformation in lamination. The method greatly improved manufacturing＇s quality and efficiency. |
