Circuit board partition device

The circuit board divider comprises a mechanically influencing or laser based numerically controllable separation device, and a workpiece carrier. The circuit board substrate (4) and the circuit board (5) are held in a course during the separation process of the workpiece carrier. The workpiece carrier comprises a basic base (28) and magnetic holding or supporting element (26) cooperating with the basic base for the guiding plate substrate. A foot section of the holding or supporting element cooperates magnetically with the basic base. The workpiece carrier has a magazine-like reception (32).

A foot section of the holding or supporting element cooperates magnetically with the basic base. The workpiece carrier has a magazine-like reception (32) for holding and supporting elements and the separation device is equipped with a gripper by which the holding or supporting elements are removed from the reception and are positionable on the basic base. The removing and positioning of the supporting elements is carried out in numerically controllable manner. The holding or supporting elements have a rejuvenating gripping or centering means by which it grips the circuit board substrate in the gripping or centering means. A permanent magnet is integrated in to the holding or supporting element or in the foot section of the holding or supporting elements. The basic base is formed from iron or iron containing and/or magnetic or magnetizable material. The reception is arranged on the basic base. The holding or supporting elements are equipped in the form of side stop means for positioning or referencing the substrate on the workpiece carriers that are magnetically fixable, are equipped vertically to the circuit board plain over the substrate and are applied in the plain of the substrate externally against the substrate. The side stop element has a graduation or slit-like groove stretching parallel to the plain of the basic base in which an edge of the substrate grips and the substrate is fixable in vertical direction to the workpiece
