An acid solution formulated specifically to remove the chromate coating from copper-clad laminate prior to innerlayer cleaning and imaging, on oxide lines or in applications where the chromate coating must be removed prior to microetching.
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.
Acidic solution used to clean metal surfaces. VersaCLEAN 470 removes metal oxides,
light oils and other organic contaminants. It is supplied in concentrated form and should be
diluted with water, as specified below. VersaCLEAN 470 can be followed by a microetch to
achieve increased adhesion when needed.
