Features
- High speeds enabled by the units ability to center wafers and perform angle alignment without seperate chucking.
- Compatible with multiple wafers:50.8-100mm SEMI/JEIDA silicon wafers.
- Wafer size and nocth/flat are automatically recongnize,eliminating the need for host controller settings.
- Built-in controller for a compact design.
- Controllable through RS-232C or RS-485 serial interface or through photo I/O parallel communications.
- Configurable for compound semiconductor wafers and transparent glass wafers by utilizing CCD photo receiver for line sensor.
