Industrial 03-20-04940 Printed Circuit Board Assembly

Description:

The Ultratech Stepper 03-20-04940 5 Axis Stage ASH PCB is an industrial motion control printed circuit board (PCB) designed to control the five-axis wafer stage assembly in Ultratech semiconductor photolithography systems. Commonly installed in Ultratech 4700 and Titan wafer steppers where it operates in conjunction with the 03-20-00784 VME Slave Processor to provide precise stage positioning and synchronized motion control during wafer alignment and exposure. Semiconductor equipment technicians and field service engineers use this board for replacement of failed stage control PCBs, preventive maintenance, and restoration of accurate lithography system performance.

Applications:

The Ultratech Stepper 03-20-04940 5 Axis Stage ASH PCB is commonly used in semiconductor wafer fabrication, MEMS manufacturing, advanced packaging, and research facilities operating Ultratech 4700 and Titan photolithography systems. The board interfaces with the 03-20-00784 VME Slave Processor to control five-axis stage motion, ensuring precise X-Y positioning, focus, and alignment required for high-resolution lithographic exposure. Compatibility should be verified using the original part number, board revision, and applicable Ultratech stepper model before installation.
