Copper corrosion inhibition in printed circuit board production
The inhibiting efficiency of imidazole derivatives (4-methyl-5-hydroxymethylimidazole and 1-buthyl-5-methylimidazole) on atmospheric corrosion of copper in printed circuit board production was investigated. The experiments were carried out on single side copper boards using a procedure based on standards applied in the electronic industry. The electrochemical investigation based on potentiodynamic polarization (Tafel extrapolation and polarization resistance measurements) on copper in investigated solutions was performed on various temperatures (25 55oC). The results obtained were compared with the efficiency of commercial inhibitor for copper.
