Reel-to-reel line copper cleaning
July 25, 2018
Q. I am working on trying to minimize the occurrence of bare spots that have been taking place on a reel-to-reel line that processes copper strands. The bare spots occur randomly throughout the 24 hour day. I have learned that the final roll to thickness of the copper is performed with mineral spirits, followed by a degreasing to remove the mineral oils, followed by annealing, and then cleaned with a sulfuric acid based solution. The copper strands are then sent to the plating shop to be plated with nickel and tin/tin-lead. Does anyone have any experience trying to clean annealed copper on a reel-to-reel line? The pretreatment cycle consists of a degreaser, electro-cleaner, and then sulfuric acid solution.
I would appreciate any help.
