Indium Corporation's Sehar Samiappan, Regional Manager for Northern California, will present "Pb-Free Flux Technology and Influence on Cleaning" at the SMTA Silicon Valley Chapter’s PCB Cleaning Technology Workshop and Roundtable Discussion today. The event will be held from 3:00–6:00pm at Bestronics' facility in San Jose, California.

This presentation details the challenges of Pb-free soldering, including temperature settings, wetting, miniaturization, air reflow, and halogen-free. Samiappan will discuss how flux features impact cleaning options, including the use of preforms on bottom-terminated components to prevent wet flux conditions and significantly reduce voiding.
