Corrosion inhibition performance of three imidazole derivatives in acidic etching solutions to fabricate copper lines of printed circuit boards

Key Points

• Corrosion inhibition performance was notably enhanced with the use of imidazole derivatives in acidic etching solutions.
• The best-performing derivative showed a reduction of corrosion rates by approximately 85% compared to untreated surfaces.
• This analysis employs a comparative study of three imidazole derivatives in different acidic conditions, focusing on their protective capabilities.
• The findings highlight that effective corrosion inhibitors can significantly improve the longevity of copper lines in circuit boards.
