Abstract
A "Top Bottom Ball Grid Array" (TB-GBA) is described, that takes advantage of existing BGA and CSP techniques, to create a new package for SCMs, MCMs, sensors and actuators. By using a pin-compatible BGA configuration at the bottom and the top of the carrier, a 3D stack assembly of several TB-BGAs is possible. As demonstrators ceramic TB-BGAs are actually developed as single chip modules (SCMs) and multichip modules (MCMs). They will be mounted as intelligent sensors bus interfaces in convetional sensor casings. A full operating 16-bit-processor-unit including microcontroller, SRAM, EEPROM, CAN bus interface, oscillator and SMD components will require a volume of only 1.2 cm3.
