An electroplating apparatus provides high current electrical connections in a small area to a workpiece. The contact area may use a dendrite surface to improve the connection. An insulative gasket prevents electroplating fluids from entering the region about the contact area. A heavy core laminated within a supporting structure provides uniform current distribution of high electrical currents to the dendrite covered contact areas.

[ What is claimed is:] [1.] An electroplating rack for holding a workpiece during plating, comprising:a supporting structure having an electrically insulative surface positioned about an electrically conductive core with at least two openings in said insulative surface exposing at least two areas of said electrically conductive core;a plating current source contact attached to a first of said at least two areas of said electrically conductive core;a second contact for providing an electrical connection to a workpiece, said second contact attached to and making electrical connection to a second of said at least two areas of said electrically conductive core; andan electrically insulative gasket positioned about said second contact to prevent electroplating fluid from contacting said second contact when said second contact provides said electrical connection to said workpiece.
