The effects of long-term storage on the solderability of immersion silver coatings.
Abstract
The solderability of an immersion Ag finish was evaluated after the exposure of test specimens to a Battelle Class II environment, which accelerates the storage conditions of light industrial surroundings. The solderability metric was the contact angle, (?C), as determined by the meniscometer/wetting balance technique. Auger surface and depth profile analyses were utilized to identify changes in the coating chemistry. The solderability test results indicate that there was no appreciable loss in solderability when the immersion Ag coated coupons were packaged in vapor phase corrosion (VPC) inhibitor bags and/or inhibitor bags with VPC inhibitor paper and aged for 8 hours, 1 week or 2 weeks in the Battelle Class II environment. An increase in surface carbon concentration after aging did not appear to significantly affect solderability.
