Main Functions

Acts as analog signal interface between the VME‑based main system controller and process‑chamber field analog sensors & actuators. It performs analog‑to‑digital (A/D) conversion for incoming sensor signals and digital‑to‑analog (D/A) conversion for outgoing control set‑points.
Multi‑channel analog input: acquires real‑time analog voltage/current signals from pressure transducers, thermocouples, temperature sensors, and process‑monitoring detectors inside vacuum chamber. It filters and conditions raw field signals to suppress plasma‑generated electromagnetic noise inside the tool.

APPLIED MATERIALS Analog IO Board P/N:0100‑03974

Multi‑channel analog output: converts digital commands from host CPU into precise analog voltage signals to drive mass flow controllers (MFC), heater power control loops, throttle valve positioning and other analog‑controlled process hardware.
Provides signal isolation for field loops to protect main controller circuitry from surge, ground loop interference and high‑voltage noise from plasma chamber environment.
Transmits sampled analog measurement data over VME bus to system host for recipe execution, closed‑loop process regulation, data logging and fault alarm triggering.
Supports equipment diagnostic function: reports abnormal signal range to the tool fault log for maintenance troubleshooting.

APPLIED MATERIALS Analog IO Board P/N:0100‑03974

Designed for AMAT legacy VME‑architecture semiconductor wafer processing platforms, deployed inside equipment control rack as plug‑in VME board module.More products: www.plcva.com
Core analog control component for etch, PVD, CVD thin‑film deposition process chambers. It maintains closed‑loop control of gas flow, chamber pressure, pedestal temperature during wafer fabrication.
Responsible for high‑precision analog measurement and set‑point output to guarantee process repeatability, wafer‑to‑wafer uniformity and process‑recipe consistency in fab production.
Part number 0100‑03974 is OEM original spare PCB assembly, used as replacement spare part for fab equipment maintenance. When the original analog I/O board fails, this unit restores chamber analog monitoring and control capability, minimizing tool downtime.
