An acid, non-etching cleaner that provides the most effective removal of chromate conversion coating from copper laminate. LAYER CLEAN CR also removes soils such as fingerprints and oxides. Used prior to photoresist lamination, it reduces imaging defects by improving photoresist adhesion. LAYER CLEAN CR’s non-chelating, non-chloride formula cleans and conditions copper surfaces, and provides consistent high speed cleaning at low concentrations. It is effective in both spray and soak applications.
