Product manual:

Product Overview

AMAT Applied Materials 903172-001 Input/Output Module (Liquid Source I/O PCB/I Board) is a specialized circuit board used for liquid supply and management subsystems in semiconductor process equipment.
This module is responsible for signal acquisition of liquid source related sensors and actuators, driving output, and interface communication with the main control system,
It is a key electronic unit for liquid source control and monitoring circuits.

Technical characteristics (speculation)

Signal conditioning and isolation: equipped with signal buffering, filtering, and isolation circuits,
Ensure reliable transmission of weak signals in noisy environments and protect the main control.

Drive capability: The output end has a drive stage (open collector electrode, relay drive, or low-power driver),
It can directly control small actuators on site or control larger loads through intermediate relays.

Bus/Backplane Interface: Equipped with standard plug/backplane interfaces for connecting to the device's main control unit,
Used for data and power transmission, compatible with internal communication structures of devices.

Diagnosis and status indication: may include self check, fault indication, and LED status indication for rapid on-site fault location.

Version management: There are revised versions (such as Rev B), and different revisions are involved in component selection
There may be differences in interface pins or wiring, and compatibility with the main control/chassis needs to be confirmed.

Industrial grade reliability: Component selection and PCB process meet the high reliability and long-term operation requirements of semiconductor equipment,
Considering anti-interference and temperature stability.

Application scenarios

Sensing and driving of the chemicals/liquid delivery control subsystem.

Control and monitor chemical transfer pumps, proportional valves, solenoid valves, flow meters, pressure sensors, and level switches.

Equipment that requires precise management of liquid ratio and supply in semiconductor etching, deposition, or cleaning processes.

Cooperate with the machine control board or vacuum/gas management chassis as the on-site interface card for the equipment liquid circuit.
