Industrial 03-20-01955 Printed Circuit Board Assembly

Description:

The Ultratech Stepper 03-20-01955 5 Axis Focus A/D Board is an industrial printed circuit board (PCB) designed to process analog-to-digital focus signals and control the five-axis autofocus system in Ultratech semiconductor photolithography equipment. Commonly installed in Ultratech 4700, 6700, Titan, and Saturn wafer steppers where it supports precise focus measurement and stage positioning during wafer exposure. Semiconductor equipment technicians and field service engineers use this board for replacement of failed focus control PCBs, preventive maintenance, and restoration of accurate lithography performance.

Applications:

The Ultratech Stepper 03-20-01955 5 Axis Focus A/D Board is commonly used in semiconductor wafer fabrication, MEMS manufacturing, advanced packaging, and research facilities operating Ultratech photolithography systems. The board converts and processes analog signals from the five-axis focus subsystem, enabling real-time autofocus control and precise wafer stage positioning for high-resolution exposure. Compatibility should be verified using the original part number, revision level, and applicable Ultratech stepper model before installation.
