  • PCB Gold Fingers – Specifications & What You Should Know

    Chemical composition: For maximum rigidity along the edges of PCB contacts, the gold plating should consist of between 5 and 10 percent cobalt. Thickness: The plating thickness of gold fingers should always fall within the range of 2 to 50 microinches. The standard thicknesses by size are 0.031 inches, 0.062 inches, 0.093 inches and 0.125 inches.
