Lessons Learned – Rusty Integrated Circuits (~1973)
Year: 1996
Abstract: Abstract:
During the Viking program, rust spots were observed on the gold-plated Kovar lids of a number of flat pack ICs. The cause was suspected to be chlorine from the lead tinning operation, and various polymeric coatings failed to prevent further corrosion.
Following the use of any chlorinated product, a thorough and complete cleaning to remove all residual chlorine contamination is a necessity.
