A powdered material that is mixed with water and sulfuric acid to make a mild etch solution for copper and copper alloys. The operating solution provides a bright, clean, uniformly etched copper surface on printed circuit boards. CIRCUTEK ME-515 operating solution is specially formulated to be used in place of a sulfuric/peroxide or sodium or ammonium persulfate etching solution. It is excellent for removing tarnish and oxidation from the copper surface, and can be used prior to electroless and electrolytic plating, after tab stripping.
When used prior to electrolytic plating as part of a pattern cleaning system, CIRCUTEK ME-515 cleans and etches copper surfaces. It aids in the removal of dry film binder residues that penetrate into the copper-clad surface of printed circuit boards.

Equipment Cleaner II removes water hardness, photoresist and soldermask scum and metal salt deposits from chemical processing equipment. Specifically developed for the Printed Circuit Board and Chemical Milling Industries, it will safely clean any spray equipment without damage to any metal or plastic. Equipment Cleaner II may be used at any temperature the equipment can safely handle, and may be reused until all the capacity is consumed. Equipment Cleaner II is a product that cleans: • Dry film developer residues • Dry film stripper residues • Solder stripper residues • Cleaner residues • Etcher residues (ammoniacal, or cupric) • Soldermask Developer residue • Tin Stripper Iron residue
An acid soak cleaner that removes oxidation, tarnish and organic soils from copper surfaces. POSICLEAN™MRis formulated to clean effectively in a variety of applications such as pre-clean prior to copper pattern plate, prior to dry film lamination, prior tooxide process, and as a pre-clean for tin or tin/lead electroplating. POSICLEAN™MRcan be followed by a microetch when necessary for increased adhesion.POSICLEAN™MRis a close relative ofPOSICLEAN™M.
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
