Indium Corporation’s Sehar Samiappan, area technical manager for North Malaysia, the Philippines, and Vietnam, will present at the SMTA Penang Chapter’s meeting on Aug. 21.
Sehar will present The Use of Solder Preforms in PiP, NanoFoil®, and QFN Void Reduction Applications. This presentation discusses how prefabricated solder forms (preforms) are made and used in demanding electronics assembly applications.
Solder preforms enable precise positioning, as well as volume consistency. They are used in the Pin-in-Paste (PiP) process to eliminate a wave soldering process step, thus providing full barrel fill; in a solder joint fortification process, providing increased solder volume; and in the QFN assembly process to reduce voiding. The presentation will also discuss the use of NanoFoil® preforms for heat-sensitive applications.
Sehar provides field technical support to Indium Corporation’s customers. He conducts process evaluations, product trainings, designs of experiments (DOEs), and helps diagnose productivity issues in customers’ factories.
