Abstract

Inhibiting efficiencies of various imidazole derivatives on atmospheric corrosion of copper on printed circuit boards were investigated. Experiments were carried out on double sided copper boards using a procedure based on international standards and applied in the electronics industry. Electrochemical measurements were performed on copper in solutions containing imidazole derivatives, under stationary and flow conditions. The influence of flow velocity and temperature on the inhibiting characteristics was investigated. The imidazole derivatives studied have good inhibiting properties for copper against atmospheric corrosion.
