The multiple printed circuit board is shoved from the front between the two wedge shaped separation tools, whereby it slides in its carving.
The space between these separation tools is smaller than the thickness of the multiple printed circuit board.
Triggered off by pedal the upper separation tool goes down and separates the board (effect of the wedge).
The tools do not touch each other during the process. Damage to the components or conductors is ruled out altogether as the cutting forces only act upon the scored line.
Furthermore, the cutting process is is absolutely even and parallel along the entire length.
Painstaking separation of this nature is of particular significance for SMD-type printed circuit boards.
