A copper plating additive for acid sulfate plating baths designed specifically for high throwing power through-hole plating of printed circuit boards. CuBrite PC-525 produces bright copper deposits that provide consistent thermal stress performance. CuBrite PC-525 is a single, clear addition agent, added on an ampere hour basis, which is used to control the brightness and physical properties of the deposit. The extreme stability of this additive greatly reduces the need for routine solution purification.
Formulated to remove fully aqueous dry films and screen ink resists in soak or spray applications. DUAL STRIP will generally break dry films into particles suitable for filtration. DUAL STRIP has a low VOC content for reduced air emissions. DUAL STRIP BAT contains additional copper brightening and antitarnish agents that produce a bright, uniform copper surface for automatic optical inspection and better etching characteristics.
A liquid 45% potassium carbonate concentrate formulated to develop fully aqueous dry film photoresists and photoimageable solder masks. DX-45 HW contains a unique blend of ingredients to ensure straight sidewalls and will help clean the foot” of underdeveloped polymer. Furthermore
FlexClean DM is a powerful, non-foaming and free rinsing alkaline cleaner specifically formulated to clean copper on exposed alkalisensitive substrates including polyimide. It will remove oven baked residues, oxidation, fingerprints and oils, all without attack of alkali sensitive substrates or removal of any copper metal. Use of FlexClean DM will leave the copper surface bright, oxidation-free and ready for photoresist application or oxide process. FlexClean DM may be used in conjunction with an acid cleaner, or if required, a light microetch. If a microetch is used, much lower levels of metal are fully acceptable thus minimizing costs and reject rate.
