CHROME/Clean is a concentrated, non-etching, free-rinsing acid cleaner designed specifically to remove chromate and zincate anti-tarnish costings from copper foil. It will also remove light oils, fingerprints, and oxidized copper from copper surfaces prior to resist lamination and/or hot air solder leveling. CHROME/Clean can be operated at concentrations of 5-20% and temperatures of 70-140F and is available in formulations suitable for either spray (AC-1S) or immersion applications (AC-1).
CHROME/Clean contains oxidation inhibitors to inhibit copper oxidation prior to further processing. These inhibitors will also promote dry film adhesion. It should not be used as a pre-clean prior to electrolytic or immersion plating applications without first consulting Seacole.
