A matte acid copper plating additive formulated for plating baths with high throwing power resulting in excellent surface to hole thickness ratios in through-hole plating of printed circuit boards. Based on economical copper sulfate and sulfuric acid, it is easy to make up, operate and control. CuBrite CF-110is a single grain refining agent that is added on an ampere hour basis and is notremoved by circulation of the plating solution through afilter packed with carbon. The addition agent reaction products and organic contamination can thus be removed on a continuous basis to assure excellent deposit ductility. CuBrite CF-110produces fine-grained, soft, matte deposits that insure good solderability, resist adhesion and etch characteristics.
ElectroClean EChas been used in automated reverse current(anodic) cleaning machines, such as the machine offered by the ChemcutCorporation, but can be used in any automated cleaning process. ElectroClean ECremoves any coatings, organic soils, fingerprints. When cleaning copper, ElectroClean ECis often followed by an acid cleaner, but can be followedby a microetch.This will usually not be necessary when ElectroClean ECis used as an anodic electrocleaner.ElectroClean ECcan be used for cleaningcopper, iron and stainless steel.Machine clean-out is facilitated as sludging is negligible. Solution life is monitored by checking metal content. Change out working solution when sludging is observed, or metal content exceeds 5 grams per liter.
