The Improvement of Al-Cu Alloy Cl-Corrosion Resistance

In this work, based on the actual production and application, we analyzed various factors to improve the Cl-corrosion resistance of Al-Cu, including dry etch (strip included), solvent clean, and some influence factors. The best scheme to expand the corrosion window is to improve dry etch and solvent clean, and other influence factors can further improve the corrosion resistance of Al-Cu. These factors can be combined according to the needs.
