Improving Yields of Inner Layers and Flexible Composites with One Step Cleaning Without a Microetch

Abstract – Maintenance of dimensional tolerances on thin core material is maximized when process steps are minimized and surface roughening by microetching or other means is eliminated. This need can be addressed by combining in a single processing chemistry the ability to clean panels of organic surface contaminants and oxides, remove chromate conversion coatings, and apply an adhesion promoting layer that acts as an oxidation inhibitor and eliminates the need for a microetch or pre-roughened (DSTF) foil to achieve the degree of dry film adhesion necessary for fine line work.
