SDM-121 Motorized PCB Depaneler

Motor-driven SDM-121 separates v-scored PCBs without stress to boards, components or solder joints, eliminating post-breakout defects such as delamination and microcracking, even when components are located as close as 1 mm to the scoring line. Operation is simple: the blades are aligned to the score line, the blade height is locked, and a depaneling speed is selected. When the operator activates the foot switch, the topside circular blade moves automatically along the v-groove, providing a smooth, burr-free cut without operator guidance. The large processing table can be angled to allow separated PCBs to fall away from the cutter. For safety, the circular blade is shielded by shatterproof Plexiglas while light sensors halt the blade immediately if an obstruction is detected. SDM-121 is suited for medium to high-volume production. A maximum component height of 32 mm provides sufficient clearance for most through-hole components and virtually all SMDs. The SDM-121 is available with 445 mm (17.5") or 483 mm (19") maximum cutting length. Cut length is fully programmable; programmed length is displayed on an LED readout.
