VersaPrep is formulated to microetch multiple metallic surfaces and thus improve their processing including lamination, imaging and solder mask application. Microetching results in surfaces that are cleaner, with removed or reduced oxide and with higher roughness. These mechanisms occur to a different extent on different metals. VersaPrep is effective on aluminum, stainless steel, copper, copper alloys and selected other alloys such as Inconel. Different substrates can be treated with simple adjustments of concentration, temperature and contact time. VersaPrep can be used in either spray or soak mode.
MicroClean CuLX is a micro-cleaner” that is designed to remove extremely tenacious soils from copper
An acid, organic, non-etching cleaner that has been specifically formulated to remove organic and inorganic contaminants. NC ACID CLEANER removes soils such as fingerprints, oxides and chromate conversion coating prior to photoresist lamination, oxide treatment, and multilayer lamination to improve adhesion. It is compatible with photoresists making it effective for pattern plate cleaning. Its non-chelating formula cleans and conditions copper surfaces and can be followed by a microetch for optimum performance. It is effective in both spray and soak applications.
A liquid persulfate-based copper microetch that is pre-mixed with sulfuric acid. ME 515L removes copper uniformly, providing good topography for subsequent processing. It can be used wherever a microetch is needed; prior to plating, resist lamination, solder mask over bare copper application, or solder leveling. ME 515L can be used in either soak or spray applications.
