Q. What cleaner should be used to clean ceramic (alumina) where the ceramic electronic packages that have tungsten, gold, and/or gold/tin metallization?
A. To clean metallized ceramic electronic packages, we recommend using 1-2% Alconox® Powdered Precision Cleaner in a heated ultrasonic followed by a thorough deionized water rinse. Alconox detergent is a free rinsing detergent that can rinse away without leaving interfering residues. Alconox powder contains excellent dispersants to remove particulates and overcome electrostatic attractions of residues on the ceramic. The wetting agents in Alconox detergent facilitate dispersant interaction and reduce hydrophobic interference with cleaning. The emulsifiers remove oils and fingerprints.
