Quantum Etch™

A stabilized peroxide product for use with sulfuric acid to form a peroxide/sulfuric microetch. QUANTUM ETCH provides a superior microetch which can be used for inner layer processing, pre-plate cleaning, and cleaning prior to solder leveling. For pre-plate cleaning of panels plated with electroless copper, use the low etch rate operating conditions. QUANTUM ETCH produces a uniformly etched surface, and will maintain a constant desired etch rate over a broad solubility range of copper sulfate in the bath.
