Process Elemental Analysis by EDXRF of Chemical Bath for Copper Foil Surface Treatment

Surface treating is an important part in the manufacture of copper foil for the electronics industry. Surface treatments are used to clean the copper foil, to create roughing and heat resistance treatments, and to make single or multiple layer thin film coatings to prevent oxidation or enhance the electro-chemical properties of the copper foil. The chemical baths must be constantly monitored to ensure the highest quality surface treatments. This application note demonstrates how the NEX OL analyzer can meet the analytical needs for trend analysis of bath composition.
