Abstract

The present invention relates to a copper ball insertion machine, for integrating metal inserts in via holes provided through a printed circuit board (PCB), comprising a motor driven X-Y table (2) with the PCB on top. The X-Y table (2) is adjustable to position a selected via hole in a predetermined location aligned with a closable outlet opening (12) of a movable container (6) for metal inserts. The container is by means of a clamping cylinder (28) displaceable for clamping the part of the PCB adjacent said via hole against the working surface (2) of said X-Y table. By means of a pivoting cylinder (20) the container is rotatable for feeding one metal insert through the outlet opening (12) into said via hole. A stamp (30) is drivable by a hammer cylinder (40) for compressing said metal insert to shape and deform it into a tight fit with the via hole.
