Chemical-Free Removal of Ag₂S Tarnish Layers Using Pulsed Laser Irradiation: Optical, Chemical, and Electrical Evaluation

Abstract Silver-coated electrical connectors are prone to the formation of silver sulfide (Ag₂S) tarnish layers, which impair both optical appearance and electrical performance. Conventional chemical cleaning can remove these layers effectively, although it may leave undesirable...
