Abstract
A process for electroplating a substrate by coating the substrate with a coating of conductive particles. The process is characterized by a pretreatment sequence that includes contact of the substrate with a single solution containing a reducing agent and a polyelectrolyte. The use of the single solution decreases the incidence of interconnect defects in printed circuit manufacture.
