Abstract :
We developed a embedded card-type processor, RICE2SPC, for ATM (Asynchronous Transfer Mode) switching systems. To reduce the size of the card to that of ordinary credit cards, we developed ASIC (Application Specific Integrated Circuit) solutions for peripheral circuits of the CPU, LSI packaging by BGA (Ball Grid Array), board by build-up process, both outer layer plating copper and inner layer copper foil with radiating effect for board and multicore floating connector for surface mounting as well as their packaging technologies. Furthermore, all parts were designed to be mounted on surface in order to decrease costs and enable their production by conventional facilities. By various types of testing, their reliability was examined
