Paper Abstract

Effective power dissipation in VLSI packaging has become a performance limiting criterion in small form factor, high performance hard disk drive applications. While potential solutions may exist, many come with unacceptable associated costs. Silicon systems and seagate technology is developed a program to identify suitable packaging solutions for the associated cost/performance tradeoff. For devices with power dissipation of 1W or less, the standard TQFP was the optimum choice. For power dissipation between 1W and 1.7W, a standard TQFP with leadfingers extending to the diepaddle is sufficient. For advanced generation devices running very near 2W, there are two possible solutions: a deep downset TQFP and a CBGA with thermal vias.
