Formulated to remove dirt, oil, fingerprints and other soils from copper surfaces without etching the copper. ULTRACLEAN NF is especially recommended for cleaning Invar/copper laminate and double treated copper foil. Also for use prior to resist lamination, oxide treatment and plating processes. Its non-chelating formula allows for easy waste treatment. ULTRACLEAN NF is non-foaming for use in conveyorized spray applications.
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.
An acid soak cleaner that removes oxidation, tarnish and organic soils from copper surfaces. POSICLEAN M is formulated to clean effectively in a variety of applications such as pre-clean prior to copper pattern plate, prior to dry film lamination, prior to oxide process, and as a pre-clean for tin or tin/lead electroplating. POSICLEAN M can be followed by a microetch when necessary for increased adhesion.
