Nikon 4S288-370-1 preamplifier unit: position signal translator for lithography machines
This 4S288-370-1 is a preamplifier manufactured by Queensgate Instruments for Nikon in the UK, model NSPA02/B. It is used in immersion lithography machines such as Nikon NSR-S620D to amplify weak signals from position sensors to a level that the controller can understand.
Five core characteristics:
1. Queensgate Instruments OEM, model NSPA02/B, is part of the precision position sensing system.
2. Responsible for primary amplification and conditioning of weak displacement signals captured by sensors to ensure signal transmission is not distorted.
3. Nikon NSR-S620D lithography machine matching components, commonly used in ArF immersion scanning lithography systems.
4. Plug in card module design, installed in the main control rack for easy maintenance and replacement.
5. Made in the UK with solid craftsmanship, meeting the stringent requirements of semiconductor equipment.
Five key parameters:
1. Part number 4S288-370-1, model NSPA02/B.
2. Queensgate Instruments brand, used for Nikon NSR series lithography machines.
3. Commonly seen in Nikon NSR-S620D ArF immersion scanning lithography system.
4. It belongs to the preamplifier unit of the position sensing system.
5. The second-hand market mostly consists of fully functional disassembled spare parts.
Five typical applications:
1. Nikon NSR-S620D lithography machine position sensor signal amplification.
2. Precise position feedback of lithography machine wafer stage and mask stage.
3. Replacement of spare parts in the maintenance of Nikon NSR series lithography equipment.
4. Signal conditioning for positioning system of lithography interferometer.
5. Renovation and maintenance of second-hand semiconductor equipment.
The Nikon 4S288-370-1 preamplifier plays the role of a signal translator in the precision positioning system of lithography machines. It is not conspicuous, but whether the crystal frustum can move accurately and whether the engraving accuracy can meet the standard are directly related to it. For friends who maintain lithography machines such as NSR-S620D, understanding this board is helpful for signal link troubleshooting, and having it prepared is also reassuring.
