Abstract

A TQFP (Thin Quad Flat Pack) package has been developed that has very superior electrical and thermal performance when compared to a plastic molded TQFP package. The high performance TQFP is based on Olin's MQUAD technology; a packaging scheme where the plastic mold compound is replaced by an anodized aluminum base and lid adhesively sealed to the leadframe. The package uses the same IR or VPR board mounting profile as a plastic package, weighs the same as a plastic package, and is dimensionally equivalent to a plastic package.<>

高性能TQFP封装的开发
与塑料模压TQFP封装相比,一种TQFP (Thin Quad Flat Pack)封装已经开发出具有非常优越的电气和热性能。高性能TQFP基于Olin的MQUAD技术;一种包装方案,其中塑料模具化合物由阳极氧化铝底座和密封在引线框架上的盖子代替。该封装采用与塑料封装相同的IR或VPR板安装型材,重量与塑料封装相同,尺寸与塑料封装相当。
