How it works
A wafer-mapping LED PCB is an electronics board used in an optical or LED-based wafer-detection/mapping subsystem.
Wafer mapping helps verify wafer presence, slot position, and handling status; board failure can cause mapping errors or robot transfer faults.
Technical guide
LED printed circuit board
A PCB populated with LEDs and interface electronics.
LED output, board alignment, connector condition, and revision can affect mapping accuracy.
Verify: LED function; connector condition; revision; mounting alignment; board cleanliness
optical wafer mapping
A wafer-detection method using light emitters/sensors to identify wafer presence or slot position.
Accurate mapping prevents wafer-handling collisions, mis-picks, and cassette/load lock errors.
Verify: emitter/sensor alignment; LED wavelength or intensity if specified; board revision; controller compatibility
