AMAT 0190-02076 Water Leak Detector / CCM Board

AMAT   0190-02076   Water Leak Detector / CCM Board

Introduction

The AMAT 0190-02076 is a CCM (Chamber Control Module) Water Leak Detector PCB.

In semiconductor manufacturing, liquid cooling is essential for high-power components like RF generators and electrostatic chucks.

This board acts as a critical safety interlock, providing real-time moisture detection within the tool’s mainframe or gas box.

It is designed to trigger an immediate system shutdown (Interlock) if a leak is detected, preventing catastrophic damage to high-voltage electronics and vacuum integrity.

3. Related Models

The 0190-02076 is often integrated into larger control modules or found alongside these interface boards:

AMAT 0110-02076: The primary assembly designation for this detector board.

AMAT 0190-02362: Mainframe Interface Relays Board (often receives the leak signal).

AMAT 0190-23441: Interlock Module (300mm Enabler tools).

AMAT 0010-26286: Controller Assembly CCM DPS232 (which often houses this PCB).

4. Application Cases

RF Generator Cooling: Monitoring the water lines that cool the RF matching networks to prevent electrical arcing from leaks.

Heat Exchanger Oversight: Used in Centura and Producer systems to monitor the secondary cooling loops for the wafer pedestal (Heater/ESC).

Facility Interface: Acting as the “first responder” in the tool’s sub-fab or mainframe floor where coolant manifold connections are most prone to vibration-induced leaks.

5. Product Advantages and Features

Rapid Response Time: Designed with high-sensitivity trace patterns to detect even milliliter-scale moisture accumulation.

Failsafe Design: Integrated directly into the tool’s hardware interlock string; if the board loses power or fails, the tool defaults to a “Safe” (stopped) state.

Corrosion Resistant: The PCB traces are often gold-plated or specially coated to prevent false positives caused by high-humidity cleanroom environments.

Compact CCM Form Factor: Fits into standard M-type or 3U Compact PCI slots common in AMAT tool racks.

6. Other Models in the Same Series

This board is part of the 0190-XXXXX electronic control series:

0190-02363: Mainframe Interlock 2-Relay Board.

0190-10208: 300mm Mainframe Interface PCB.

0190-34511: DeviceNet Bus Scanner Module (for digital signal reporting).

7. Installation and Maintenance

Installation

ESD Safety: Always wear a grounded wrist strap; the CMOS components on this board are highly sensitive to static.

Slot Alignment: Ensure the PCB is firmly seated in the CCM rack guide rails before engaging the captive screws.

Sensor Connection: Connect the external moisture sensor pads (usually located in the bottom drip pans of the tool) to the input header on the board.

Maintenance

Monthly Test: Manually “trip” the sensor using a damp cloth (if protocol allows) to ensure the software recognizes the leak alarm and triggers the interlock.

Visual Inspection: Check for “creepage” or residue on the board surface which can cause high-impedance shorts and false alarms.

8. Unique Product Description

The AMAT 0190-02076 is the “insurance policy” of a semiconductor tool.

While complex processors manage the chemistry of a wafer, this board performs the humble but vital task of ensuring the tool doesn’t “drown” in its own cooling water.

Its presence is the difference between a minor maintenance task and a multi-million dollar hardware loss due to a coolant-induced electrical short.
