Working Principle
The DPEM-440A operates as part of an ASML lithography system. Depending on its exact subsystem role, it may process control signals, manage power distribution, support motion or encoder interfaces, or provide auxiliary electronic functions required by the lithography tool. It communicates with other ASML modules and the main control system to maintain precise equipment operation. All functions are executed under ASML system software and safety supervision.
