Vacuum Coaters precious metal coating alternative processes

Vacuum Coaters precious metal coating alternative processes, reduce the consumption of alternative precious metals precious metal plating process. There are more mature alternative to the ternary alloy plating silver plated.
(1) on behalf of the ternary alloy silver plating
Copper Tin Zinc Alloy Plating due to bright silver and anti-tarnish performance is better than silver, and thus outside the assembly of connectors for commonly used instead of silverware in the electronic connector industry, then the main whichever appearance since bright colors and easy to change color, the inner conductor is still using silver conductive properties to ensure not a big impact.
Ternary alloy process is as follows: a self-test a chemical degreasing a washing hung a washing an ultrasonic degreasing a hot water wash a one-etching a degreasing washing a wash of an electrochemical activation of a washing a washing - washing one a pre-wash a copper one washing a washing acid copper plating an activation one a wash a wash a ternary alloy plating a pure water a washing and drying a hot water one a self-test an inspection.
