Ensuring Adhesion of Conformal Coating on PCBA with Plasma
Plasma treatment ensures conformal coating adhesion on PCBAs by removing microscopic contaminants and activating surfaces at the molecular level. This increases surface energy from 30-35 dynes/cm to 45-50 dynes/cm, which prevents common failures like delamination and peeling. Why coatings fail on PCBAs Modern PCBAs face adhesion challenges that compromise long-term PCBA protection. Low surface energy […]
