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 () with the PCB on top. The X-Y table () is adjustable to position a selected via hole in a predetermined location aligned with a closable outlet opening () of a movable container () for metal inserts. The container is by means of a clamping cylinder () displaceable for clamping the part of the PCB adjacent said via hole against the working surface () of said X-Y table. By means of a pivoting cylinder () the container is rotatable for feeding one metal insert through the outlet opening () into said via hole. A stamp () is drivable by a hammer cylinder () for compressing said metal insert to shape and deform it into a tight fit with the via hole.
