MINNEAPOLIS – The SMTA has announced a series of webinars coming in March to be held in conjunction with Virtual PCB.

Go Greener in Your Cleaner, presented by Dr. Harald Wack at Zestron America, will take place Mar. 3. Attendees will learn about recent cleaning challenges, including the removal of flux residues under challenging low standoff components such as 0603 chip capacitors, while using pH-neutral de-fluxing agents, as well as alkaline chemistries with reduced VOC levels.

Also on Mar. 3, Root Cause Failure Analysis of PCB Assemblies will introduce the element of root cause failure analysis through the correlation of product and tooling design with assembly defects, including examples of actual product design, manufacturing tooling design, and SMT and PTH assembly process issues matched to actual product failures. The presentation will be given by Dale Lee of Plexus Corp.

Status of the Proliferation of Lead-Free Alloys: 2010, on Mar. 4, will provide an overview of the current Pb-free alloy proliferation, a discussion of new failure modes and how to minimize them and an outlook on how alloy convergence might occur. Ronald Lasky, Ph.D., PE, of Indium Corp. will present.
