Electroless Palladium (ENEPIG) Description Gintron PD 106 Applies cost-effective pure palladium deposit via autocatalytic electroless plating, enhancing corrosion resistance and soldering ability without the 'black pad effect' compared to ENIG process. This process can be followed by a Nickel Sulphamate (18%) bath - an excellent barrier layer before gold plating, which prevents copper migration for boards without finger contact. get a quote
