LAM Research 61-380630-00 32-Channel Temperature Controller

Description

Key Technical Specifications

The available documentation is limited, but multiple independent industrial sources identify the same part number as a 32-channel temperature process controller / 32TC. A current semiconductor-spares listing describes the unit as a working surplus component, while another industrial inventory source identifies the part as a LAM Research 32-channel temperature-control unit with thermocouple ports.

Important identification note: Some secondary-market listings provide conflicting descriptions for this part. One source incorrectly describes it as a thermal mass-flow controller, while multiple other sources identify it as a 32-channel temperature process controller. For procurement, the actual nameplate, connector configuration, and installed equipment documentation should be used to confirm the exact variant.

Product Introduction

The LAM Research 61-380630-00 is a 32-channel temperature process controller, identified in industrial spare-parts catalogs as the 32TC and associated with semiconductor manufacturing equipment. Its primary function is multi-zone temperature monitoring and control through thermocouple inputs.

This is a legacy semiconductor-equipment component, so replacement should be treated as an equipment-specific service task rather than a generic temperature-controller substitution. Verify the thermocouple wiring, channel mapping, controller revision, associated 79-10098-00 assembly, and host-tool configuration before installation.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation

Estimated time: 20–30 minutes

⚠️ Safety First: Place the semiconductor processing tool in its approved maintenance state. Follow the equipment manufacturer’s LOTO procedure before opening the controller enclosure.

Tools Required:

• ESD wrist strap
• Digital multimeter
• Appropriate screwdrivers
• Wire labels
• Smartphone/camera
• Equipment service documentation
• Current controller configuration backup

Data Backup:

1. Record the complete 61-380630-00 part number.
2. Photograph the front and rear of the controller.
3. Record the hardware revision.
4. Photograph every thermocouple connector.
5. Record channel-to-zone assignments.
6. Document controller address and communication connections.
7. Save the existing process configuration where supported.
8. Record temperature setpoints and alarm limits.

⚠️ Semiconductor temperature-control wiring is particularly easy to misidentify because multiple physically similar thermocouple connections can serve different process zones.

Stage 2: Removing the Old Controller

Estimated time: 15–25 minutes

1. Place the semiconductor tool in maintenance mode.
2. Complete the applicable LOTO procedure.
3. Verify controller power is removed.
4. Allow internal supplies to discharge.
5. Photograph all connections before disconnecting anything.
6. Label thermocouple channels individually.
7. Disconnect communication and control cables.
8. Release mounting hardware.
9. Remove the controller without stressing the connectors.
10. Inspect connectors for contamination or damaged contacts.

⚠️ Do not clean semiconductor-equipment connectors with ordinary shop solvents. Follow the tool manufacturer’s contamination-control procedure.

Stage 3: Installing the Replacement

Estimated time: 20–30 minutes

1. Verify the replacement marking: 61-380630-00.
2. Compare the replacement connector layout with the removed controller.
3. Confirm hardware revision where applicable.
4. Inspect the thermocouple interface.
5. Mount the controller securely.
6. Reconnect communication and power connections.
7. Reconnect thermocouples according to the documented channel map.
8. Confirm each connector is fully seated.
9. Verify cable routing and strain relief.

Self-Checklist:

• 61-380630-00 verified
• Hardware revision recorded
• Channel mapping documented
• Thermocouple connectors correctly installed
• Communication cable connected
• Power connections checked
• Mounting hardware secured

Stage 4: Power-On & Testing

Estimated time: 30–60 minutes

1. Perform a final visual inspection.
2. Restore controller power.
3. Observe startup diagnostics.
4. Verify the controller initializes normally.
5. Confirm all expected temperature channels are detected.
6. Compare displayed temperatures with known process/reference values.
7. Verify thermocouple polarity and channel assignments.
8. Check temperature alarm states.
9. Confirm communication with the host equipment.
10. Verify individual zone control.
11. Run the tool through an approved dry or qualification cycle.
12. Confirm stable temperature regulation before returning the equipment to production.

⚠️ Do not immediately apply production recipes after replacing a 32-channel temperature controller. A single swapped thermocouple channel can cause the controller to regulate the wrong heater zone while all displayed temperatures still appear plausible.

Frequently Asked Questions (FAQ)

What is LAM Research 61-380630-00?

The 61-380630-00 is a 32-channel temperature process controller, commonly identified as a 32TC, for LAM Research/Novellus semiconductor-processing equipment. Industrial inventory records specifically describe it as a 32-channel temperature-control unit with thermocouple ports.

Is 61-380630-00 a mass-flow controller?

Available listings conflict on this point. One reseller describes it as a thermal mass-flow controller, but multiple independent records identify 61-380630-00 as a 32-channel temperature process controller / 32TC. The latter identification is better supported by the repeated product descriptions and the related 32TC designation.

How many temperature channels does it control?

The part is identified as a 32-channel temperature controller. Radwell describes the unit as a 32-channel process-control device with thermocouple temperature ports.

Is 61-380630-00 discontinued?

Yes. Current industrial inventory records identify the part as discontinued by the manufacturer. It remains available through semiconductor-equipment spare-parts suppliers and secondary-market inventory.

What is 79-10098-00?

79-10098-00 appears in industrial listings as a related number associated with the 61-380630-00 32TC temperature controller. One listing identifies the assembly as “2 Channel Temp Cntrl, Process Controller 32TC, 79-10098-00 61-380630-00.” Because the relationship is not clearly documented in an OEM manual, verify the exact assembly designation from the equipment nameplate before ordering.

Can I replace 61-380630-00 with a generic 32-channel temperature controller?

Not as a direct drop-in replacement. The semiconductor tool may depend on specific thermocouple interfaces, channel mapping, communication protocols, alarm handling, mechanical mounting, and host-software integration. A generic controller can match the channel count while remaining electrically or functionally incompatible.

What condition should I specify when buying this part?

Specify the condition explicitly:

• New Original / New Surplus — unused inventory
• Refurbished / Tested — previously used and function-tested
• Working Surplus — tested operational unit
• Used / As-Is — condition and testing limitations clearly stated

Current secondary-market listings show all of these condition categories can occur. One current listing identifies a working surplus 61-380630-00 with a 90-day warranty, while another lists used units.

What should procurement verify before ordering?

Request photographs showing:

• 61-380630-00 nameplate
• Hardware/revision marking
• Connector arrangement
• Thermocouple interfaces
• Associated 79-10098-00 marking if present
• Actual condition
• Functional test status
• Warranty period

For this type of legacy semiconductor-equipment controller, matching the exact hardware and channel configuration is more important than matching a generic description such as “32-channel temperature controller.”
