Effects of Assembly Process Variables On Voiding At A Thermal Interface Universal Instruments Corporation Muffadal Mukadam, Electronics Manufacturing Research and Services. Krishnaswami Srihari, Thomas J. Watson, State University of New York. Jeff Schake, DEK USA Inc. Peter Borgesen, Universal Instruments Corporation. Too often, the effects of assembly process parameters are not sufficiently accounted for in the optimization of thermal interface performance. This becomes increasingly critical as demands on this performance continue to grow and alternative processes are developed. Notably, stencil printing is proving a competitive alternative to the traditional dispensing of thermal interface materials (TIMs), with potentially significant gains in units processed per hour (UPH) for some applications. The two techniques may, however, pose quite different challenges... Printed Circuit Board Equipment Exchange #5

Solder Tip #14. Lead-Free (SAC Alloy) QFP Multi Lead Soldering Technique Bob Wettermann BEST Instructors have put to video demonstrations of common hand soldering skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.
