PCB separator MAESTRO 4S
Stress-free separation of pre-scored PCBs

MAESTRO 4S separates both small and large PCBs quickly and economically without stress.

Key features:

  • Blade distance to be entered on the operation panel is set motor-driven.
  • Up to nine programs to be stored
  • Separation length to be continuously adjusted via limit switches
  • In terms of a preventive blade maintenance, the cutting performance is displayed.
Diagram

Material: FR4 1.5 mm
Residual thickness approx. 0.6 mm

By traversing the milled groove once, tensile and compressive stresses can cause damage to sensitive components located close to the groove. A second traverse and simultaneous readjustment of the blade distance already reduces stresses considerably. The quality of the assembled PCBs improves significantly.

Dial gauge
In order to separate without stress and to achieve a long service life, the circular and linear blades have to be guided along the entire separation. The dial gauge setting and regularly checking the parallelism is assembled to the carriage.

Separating aluminum

To separate aluminum with MAESTRO 4S, special adjustment is needed for the standard circular blade. For information see the operator's manual

Aluminum PCBs are manufactured in various alloys. Sample PCBs added to a request help with adjusting the circular blade and optimizing the cutting geometry.

Milled groove

The milled groove may be interrupted by cutouts.

Protruding components need a recessed linear blade.
