Electromigration damage mechanics of lead-free solder joints under pulsed DC: A computational model

by: Wei Yao, Cemal Basaran; Electronic Packaging Laboratory, State University of New York

Electromigration (EM) is a mass transportation mechanism driven by electron wind force, thermal gradient, chemical potential and stress gradient. According to Moore�s law, number of transistors on integrated circuits (ICs) doubles approximately every 2 years. Moore�s law holds true since its introduction in 1970s. This insatiable demand for smaller ICs size, larger integration and higher Input/Output (IO) count of microelectronics has made ball grid array (BGA) the most promising connection type in electronic packaging industry. This trend, however, renders EM reliability of solders joints a major bottleneck to hinder further development of electronics industry....
