WebMar 3, 2024 · A PCB surface finish is an intermetallic joint between the bare copper of the solderable area of the printed circuit board and the components. Circuit boards have a base copper surface that is susceptible to oxidation if left without a protective coating, hence the requirement of the surface finish. WebThis finish is good for many aspects of PCB applications; however, it does cause more conductor loss. The main reason ENIG causes more loss is due to nickel being about one-fourth the conductivity of copper. There is potentially another reason and that is losses related to the imaginary component of relative permeability. Permeability is ...
