Implementing Single-Row Process Plate Design for Pre-Encapsulated Lead Frame

Abstract

This paper presents the application of an innovative design of wirebond process plate during wirebonding process of thin semiconductor carrier such as the pre-encapsulated leadframe. The implementation of the specialized process plate aims to improve the conventional method of wirebonding from panel type to single-row design to reduce the occurrence of warpage on thin leadframes. In this study, an 85% reduction for warpage level is achieved after the introduction of the new design of process plate. Future works could use the improved process plate design for devices of similar configuration.
