We are using VP on all of our lead free assemblies. 1. We are getting great, very repeatable results. 2. The profiles were created during the implementation of the equipment and we only change 3 parameters for each assembly processed. Heater power,

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-µm 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.
