Abstract

In the never ending quest for smaller product size, Motorola portable radios and pagers use a variety of surface mounted chip carriers. The chip carriers con- tain microcomputers, peripheral function chips, and memory chips. The chip carrier footprints vary from having pads on the outer edges of the substrate to highly dense pad array carriers. The chip carriers require testing at the component level, and chip carriers containing embedded EEPROM also require burn-in to screen for infant mortality failures inherent with EEPROM tech- nology. It has always been a challenge to contact these devices for testing and bum-in purposes.
