ABSTRACT:
The invention comprises a two step method for the repair of "opens" in an electronic circuit wherein initially the open is contacted with a plating solution and a high frequency current is passed through the ends of the open in the circuit with the plating solution enabling the current to complete the path. Metal growth commences between the ends of the open to form a near open. Then the repair is completed by contacting the site with a high speed plating solution and applying a low frequency current.
