Features & Benefits

  • The Mac Pitch Changer transfers 25 each silicon wafers between one standard pitch plastic cassette to one non- standard pitch quartz or silicon carbide.
  • The machine may be configured to accommodate a large diversity of Plastic, TeflonĀ®, metal, Quartz,
    Silicon Carbide and Polysilicon carriers.
  • All exposed aluminum parts are hard black anodized for corrosion resistance.
  • Electronic through beam sensors are used to detect wafer presence in boats and retainers thus
    preventing accidental double loading and scratches.
  • Lift system uses ramped speed controls for gentle pick-up and landing.
  • Pressure sensors are used for both personal safety and machine safety by inhibiting machine operation.
  • Retainers default to closed position to prevent dropping wafers in the event of electrostatic discharge, loss of power, or loss of air pressure.
  • A pause function is provided to stop the lift system at any position to facilitate preventative maintenance and cleaning.
  • Single-board computer control, Operator interface is with a 12 key keypad with a 4 line LCD display.
  • Uptime will exceed 99.25%.
    • MTBF (mean time between failure): 2,500 hours
    • MTBA (mean time between assist): 1,000 hours
    • MTTR (mean time to repair): less than 1 hour


  • RS232 communications port
  • Recessed mounting
  • Vespel package for high temperature applications
