摘要

开发了一种主要适用于消费类便携式电子仪器的微控制单元(MCU)和专用集成电路(ASIC)等逻辑器件的细间距球栅阵列(FBGA)。FBGA具有一种结构,其中模具连接到具有单层导体的玻璃环氧树脂中间层。电线粘合和传递成型应用于引线框架型封装相同的方式。与传统封装相比,FBGA具有更小的机身和更高的性能。介绍了封装结构、装配工艺、性能及可靠性试验结果。

Development of fine pitch ball grid array
A fine pitch ball grid array (FBGA) has been developed which is suitable mainly for logic devices such as micro control units (MCU) and application specific integrated circuits (ASIC) for consumer portable electronic instruments. The FBGA has a construction in which a die is attached to a glass-epoxy interposer with a single layer conductor. Wire bonding and transfer molding are applied in the same manner as lead frame type packages. The FBGA has a smaller body and higher performance than conventional packages. The package structure, assembly process, performance and reliability test results are introduced.
