Title: METHOD FOR PRODUCING AT LEAST ONE ELECTRICALLY CONDUCTIVE CONNECTION IN A CIRCUIT CARRIER, AND A CIRCUIT CARRIER PRODUCED ACCORDING TO SAID METHOD
Abstract:
The invention relates to a method for producing at least one electrically conductive connection (6a, 6b, 6c) in a circuit carrier (1), which has an aluminum base layer (2), an insulating layer (3) arranged thereon, and a conductor track structure (4) arranged on the insulating layer. The electrically conductive connection is produced between the aluminum base layer and at least one conductor track (4a, 4b, 4c) of the conductor track structure (4), and at least one bore (5a, 5b, 5c) is produced which passes through the conductor track (4a, 4b, 4c) and the insulating layer (3) and extends at least up to the aluminum base layer (2). The bore is filled with an electrically conductive material in order to produce the at least one electrically conductive connection (6a, 6b, 6c), said material then undergoing a solidifying process. The invention also relates to a circuit carrier produced in this manner.
