Multi-wire-cut Electrical Discharge Machines

「DS1000」

Mitsubishi Electric

DS1000 slices cylindrical configuration semiconducting materials into thin disk-shaped wafer.The DS1000 can machine simultaneously with multiple wires, producing up to 20 sheets at a time. This machine is compatible with next generation semiconductor materials such as silicon carbide (SiC) and gallium nitride (GaN).

The machining speed is improved by 60%, the yield is improved by 40%, and the running cost is reduced by 80% compared to slicing with a wire saw with diamond abrasive grains.
