CLSR-0102B-N2CA amplifier

CLSR-0102B-N2CA amplifier 

 Introduction

The CLSR-0102B-N2CA amplifier belongs to the piezoelectric ceramic driver amplifier of lithography machines. It is used to receive weak control signals from the motherboard, output power to drive optical micro components, and directly affect the actual accuracy of alignment and focusing.

Product Features

1. Good linearity of output signal, precise restoration of small displacement commands, less likely to cause position deviation, ensuring nanoscale fine-tuning effect

2. Equipped with overcurrent and overheating protection, it will actively limit the output in case of abnormal load, avoiding direct damage to expensive piezoelectric ceramic actuators

3. Internally perform signal filtering processing to filter electromagnetic interference in the cabinet, preventing clutter from entering the drive signal and causing the mechanism to shake inexplicably

4. Support real-time feedback collection, transmit the status of the execution end back to the machine master for convenient closed-loop operation and fault troubleshooting

5. Compact board size, rack slot installation, easy replacement, reducing the workload of on-site disassembly and debugging

Product Specifications

1. Cabinet backplane power supply, compatible with the internal power supply circuit of the lithography machine

2. Multiple piezoelectric drive output channels, matched with multiple sets of micro motion actuators

3. Equipped with feedback signal interface, connected to the closed-loop control system of the whole machine

4. The working temperature is 5-40 ℃, which meets the operating conditions of dust-free cabinets

5. Standard industrial board form, can directly replace damaged spare parts

Application Areas

1. Photolithography alignment system driven by piezoelectric micro motion mechanism

2. Exposure light path lens micro tuning unit

3. Local precision displacement control circuit for workpiece table

4. Optical detection system power drive unit

5. Maintenance and replacement of spare parts for production line equipment

Once the performance of the CLSR-0102B-N2CA amplifier deteriorates, alignment drift and unstable focusing may occur, directly causing chip overprinting and affecting wafer yield
