| Abstract: | CQFP is a ceramic package with leads from four edges of the package. It is a compact, light weight, high reliability and good performance in thermal characteristics. It is suitable for surface mount assembly, It is widely used in packaging large scale integrated IC such as CMOS, ECL, and Grid Array. This article deals with topics in the critical process involved in the CQFP; such as metallization paste, precision large scale printing, big cavity iso-static pressing, pull strength for fine wire and its future direction for improvement. |
