Abstract

The effect of heat-spreader sizes on the temperature distribution, thermal resistance, and cooling power of a set of cost-effective cavity-down plastic ball grid array (PBGA) packages assembled on a FR-4 epoxy glass printed circuit board (PCB) is presented. The sizes of these packages are 35 X 35 mm and 40 X 40 mm with 4 and 5 rows of solder balls.
