The electroplating of a conductive surface by immersion in a bath requires that electrical contact with the object to be plated be established. In the case of printed circuit panel edge plating, brushes are typically used to introduce cathodic current source to the panel. Occasional damage to the panel occurs from this contact with the brushes. In a continuous plating system which uses a belt drive to propel the panel through the plating bath, the electrical connection can be accomplished by using metallic pads with abrasive surfaces to promote contact between the panel and the current source. The pads are attached to each link of the belt, and each link is electrically isolated from the other links.
