Board-Level Thermal Cycling and Drop-Test Reliability of Large, Ultrathin Glass BGA Packages for Smart Mobile Applications

Bhupender Singh, Gary Menezes, Scott McCann, Vidya Jayaram, Urmi Ray, Venky Sundaram, Raj Pulugurtha, Vanessa Smet, Rao Tummala; Institute of Electrical and Electronics Engineers (IEEE)

Glass substrates are emerging as a key alternative to silicon and conventional organic substrates for high-density and high-performance systems due to their outstanding dimensional stability, enabling sub-5-��m lithographic design rules, excellent electrical performance, and unique mechanical properties, key in achieving board-level reliability at body sizes larger than 15 �� 15 mm2.

This paper describes the first demonstration of the board-level reliability of such large, ultrathin glass ball grid array (BGA) packages directly mounted onto a system board, considering both their thermal cycling and drop-test performances.
