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.

. If the finish has tarnished is there any way to restore the immersion finish for better solder quality? Answer: The use of a more aggressive flux, something in the OAH1 category should be able to clean the surface and allow it to solder, which will also allow the solder to flow on the land areas of the terminations
