Fully automatic marking of printed circuit boards


The printed circuit boards are transferred to the topex printed circuit board marking system by an upstream conveyor, stopped in a predetermined position by a buffer, and tensioned pneumatically from below. The X/Y coordinate system places the printed circuit board in the marking position under the laser. After marking, the camera check-reads the marked code. The printed circuit board is then transferred to another conveyor belt for further processing. The printed circuit boards consist of a number of panels.
