As our world continues to evolve to an online buying market for everything for our homes, schools, and offices, you may have noticed in some cases, the quality is not exactly what you thought you saw and bought online. We have all had that men’s XL shirt we bought for dad’s birthday arrive only to fit our 7-10-year-old, or the gift for Christmas arriving in January. Is it cost vs. quality, convenience vs. going out shopping, or is it the ongoing COVID-19 situation?

ENEPIG Benefits for Gold Wire Bonding

Written by Chris Perry
Posted on November 27, 2018 at 9:15 AM

ENEPIG (Electroless Nickel, Immersion Palladium, Immersion Gold) was derived out of the need to combat the challenge with the immersion gold process and Black Pad Syndrome. Black Pad (the hyper corrosion of underlying nickel) was baffling both PCB assemblers and manufacturers. After much analysis, the root cause was determined to be the nickel deposit.

Printed Circuit Board Solderability Issues

Written by Chris Perry
Posted on August 14, 2018 at 10:29 AM

Solving solderability issues for printed circuit boards (PCBs) can be a real hassle. Nothing is more frustrating than having lined up all your materials for an assembly, only to start running the package through reflow and discover that the solder paste is wetting poorly to the pads. Immediately, the profile is checked to confirm proper parameters.
