Stripping and Replacement of Damaged Solderable Coatings

Stripping and Replacement of Damaged Solderable Coatings Electronic materials, particularly tinlead coated component leads, may degrade and acquire a poor solderability as a result of longterm storage or prolonged periods at elevated temperatures during burnin. This paper presents the results of studies on the surface chemistry and microstructure of such coatings together with a technique for stripping degraded coatings and replacing them with pristine finishes having excellent solderability. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Soldering & Surface Mount Technology Emerald Publishing

Abstract

Electronic materials, particularly tinlead coated component leads, may degrade and acquire a poor solderability as a result of longterm storage or prolonged periods at elevated temperatures during burnin. This paper presents the results of studies on the surface chemistry and microstructure of such coatings together with a technique for stripping degraded coatings and replacing them with pristine finishes having excellent solderability.
