Black Pad Electronics. This can be caused by a number of factors. Black pad is basically a reaction of the chemistry in immersion gold with the electroless nickel. It is not visually evident on the bare fab. Selective pads on one or both sides of a finished, electroless nickel immersion gold printed circuit board which appear to be partially or totally black after the thermal processes at assembly. “black pad” primarily affects bga components and will occur when using electroless nickel/immersion gold finishes on the circuit board fab. The defect is not seen as part of normal qc procedures as the immersion gold masks the appearance of the nickel under the gold. Identification and prevention of “black pad” abstract. Enig black pads are a critical defect that can weaken solder joints and compromise the reliability of electronic components. Black pad is a term that usually refers to nickel corrosion on electroless nickel and gold immersion (enig) surface finishes on pcbs. Enig (electroless nickel immersion gold) black pad refers to a specific defect that occurs in the manufacturing process of printed circuit boards (pcbs) that use the enig surface finish.
