Common PCB Quality Issues and What to Inspect For

Written by Angie Brown
Posted on June 14, 2021 at 10:10 AM

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

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.

What are Non-Conformances and How do PCB Manufacturers Fix Them?

Written by Chris Perry
Posted on August 3, 2018 at 12:37 PM

For customers and suppliers along the PCB manufacturing process, non-conformances will, unfortunately, happen from time to time. A non-conformance consists of receiving an order for printed circuit boards that do not meet your specifications or industry (IPC) standards. While dealing with these issues is obviously essential, the solution is sometimes not obvious and can put on-time delivery to your customer at risk. It is imperative that your circuit board supplier can deliver conforming product as soon as possible, which means having the procedures to get there.

Why Is A Supplier Quality Manual Still Needed?

Written by Chris Perry
Posted on June 26, 2018 at 9:02 AM

With the introduction of ISO 9001:2015, which specifies requirements for quality management systems, the statement “quality management system documentation shall include a quality manual” no longer need apply. Many celebrated this as a reprieve from previously having to fully document their quality management system. However, eliminating the supplier quality manual altogether could be a dangerous takeaway on the new standard’s intention.
