A liquid 45% potassium carbonate concentrate formulated to develop fully aqueous dry film photoresists and photoimageable solder masks. DX-45 NH contains a unique blend of ingredients to ensure straight sidewalls and will help clean the foot” of underdeveloped polymer. These same ingredients help keep the equipment clean
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.
