    摘要: A process for preparing a non-conductive substrate for electroplating is proposed. The proposed process comprises contacting the substrate, after des{acute over (m)}ear, with a combined neutralization/sacrificial coating solution followed by treatment with a carbon dispersion solution. The combined neutralization/sacrificial coating solution neutralizes permanganate residues from the desmear step and applies a sacrificial coating to metallic surfaces on the substrate. The sacrificial coating allows for easy and reliable removal of unwanted carbon residues from the metallic surfaces prior to electroplating.
