Abstract

Electrically isolated circuit lines must be connected by a commoning bar to conduct electrical current in those situations where electroplating is required in the construction of printed circuit cards, or the like. After electroplating, the commoning bar must be removed to restore electrical isolation for testing purposes. A plate-masking tape, that has an embedded conductive strip, is used to common the electrically isolated circuit lines, thereby replacing part of the commoning bar. The tape acts as a plating mask and is easily removed after use. The tape works as follows. As seen in Fig. 1, a top view of a printed circuit card 1 having circuit lines 2 with connector tabs 3 (Fig. 2) that must be commoned to permit electroplating.
