We have an immersion silver board that has a brown discoloration after processing. It's not flux residue, that normally doesn't cause this condition. Elemental analysis shows less than 1% sulfur, and I thought silver sulfide is more a black color.

A great business connection developed at the end of 2018 when Big Ass Fans (BAF) signed-off to purchase two Vector 300 selective soldering machines from Hentec Industries / RPS Automation. BAF decided to start processing their own PCB's in 2018, and by bringing the PCB assembly in house, it has allowed for better goal achievement, enhanced quality and inventory control, all while reducing overall costs. "We realized that starting up a PCB assembly operation had to be carefully planned, after all, we couldn't chance to tarnish our brand by missing deliveries or compromising our product quality," says Frank Grimard, Director of Manufacturing Engineering at Big Ass Fans. "It was understood early in the planning process that we needed three main ingredients to make this work; experienced talent, world-class manufacturing processes, and quality equipment."

Organic Solderability Preservatives (OSPs), also known as anti-tarnish, on bare copper printed circuit boards (PCBs) are becoming more prevalent in the electronics industry as the low-cost replacement to Hot Air Solder Leveling (HASL). Introducing the anti-tarnish alternative into the customer sites requires working closely with the coating supplier, assembler, and Original Equipment Manufacturer (OEM) to gain a mutual understanding of respective processing concerns and finished product requirements.

Surface finishing is an integral part of any PCB fabrication. It is generally applied to exposed Cu connectors and conductors on the board. Surface finishing has numerous important functions. It serves as a protective layer for the Cu connectors during storage. The surface finish helps minimize or reduce tarnish of the Cu substrate. Additionally, since it is the layer that comes into contact with other components during assembly, it ensures good solderability between the PCB and the component during assembly. Furthermore after assembly, the finish helps prolong the integrity of the solder joint during use. A general review of common PCB surface finishes is presented. The advantages and disadvantages of each are discussed and compared.
