Manassas, VA – November 11, 2015 ZESTRON, the global leading provider of high precision cleaning products, services and training solutions in the electronics manufacturing and semiconductor industries, is pleased to announce that Jigar Patel, M.S.Ch.E., Senior Process Engineer, will be presenting at the SMTA/CALCE LED A.R.T Symposium on November 17th.
Light emitting diodes or LEDs are widely used within modern PCBs in high power, automotive and lighting applications among others. The LED components can be soldered either through a manual or wave soldering processes. For high reliability applications, removing post solder flux residues is critical in order to maintain functionality.
This presentation reviews LED failure mechanisms such as corrosion, electrochemical migration and signal leakage. Polar ionic flux residues can cause corrosion, can enable copper electrochemical migration as well as signal leakage paths on the surface of the PCB in the presence of humidity. Thus, removing flux residues is critical to maintain reliability. Appropriate cleaning agents and equipment types for LED applications will also be reviewed. Customer case studies addressing LED cleaning applications will be presented.
The SMTA/CALCE LED A.R.T Symposium will be held from November 17-19 at the Crowne Plaza Midtown in Atlanta, GA.
