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.
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.
PreLam Cleaner is a cleaner/microetch/adhesion promoter for use on copper and other metals. It will give optimal resist adhesion both initially and during subsequent processing, where other chemicals can weaken the bond at the copper/photoresist interface. PreLam Cleaner yields a non-traditional looking panel with a bright orange color rather than a more typical matte pink.
