Lam Research 810-801237-021

Product Overview

The Lam Research 810-801237-021 is a Stepper Driver Interface PCBA designed for use in Lam Research semiconductor processing equipment. Industry sources identify the component as a Stepper Driver Interface Board, with both Rev B and Rev C versions appearing in equipment spare-parts listings.

This board provides an interface between the equipment control architecture and stepper-drive subsystems. Stepper motion is commonly used for precise positioning of mechanical assemblies inside semiconductor processing equipment. Therefore, a reliable driver interface is important for accurate movement, repeatable positioning, and stable equipment operation.

One equipment spare-parts supplier specifically lists the 810-801237-021 as a PCBA found on Lam Research Kiyo C Series systems, making equipment and revision verification particularly important before replacement.

Technical Parameters

• Manufacturer: Lam Research
• Part Number: 810-801237-021
• Product Type: Stepper Driver Interface PCBA
• Board Category: Motion-control interface board
• Referenced Revisions: Rev B / Rev C
• Primary Function: Stepper driver interfacing
• Application: Semiconductor manufacturing equipment
• Associated Equipment: Lam Research Kiyo C Series systems are referenced by an industry supplier
• Installation Type: OEM equipment PCB assembly

The available documentation does not establish complete electrical specifications such as operating voltage, current, connector pinout, or communication protocol. These values should therefore be confirmed from the applicable equipment documentation or board revision before installation.

Core Features

Precision Motion Interface

The 810-801237-021 is intended to support communication and control between semiconductor equipment electronics and stepper-drive hardware. This makes it relevant to mechanisms requiring controlled incremental movement.

OEM Equipment Integration

Rather than functioning as a standalone industrial controller, this PCBA is designed for integration within a specific Lam Research equipment architecture.

Multiple Revisions

Industry listings reference both Rev B and Rev C versions. Consequently, revision matching should be part of the replacement process.

Compact Electronic Assembly

The board integrates its interface circuitry onto a dedicated PCB assembly, helping maintain organized connections between motion-control subsystems.

Board Structure

The 810-801237-021 is a populated printed circuit board assembly rather than a simple bare PCB. Its construction generally includes interface connectors, electronic signal-conditioning and control circuitry, power-related components, and PCB traces that route signals between the equipment controller and stepper-drive subsystem.

The exact component population can vary by revision. For this reason, technicians should compare the replacement board with the installed unit before installation.

The board is also listed under descriptions such as “PCB ASSY STEP DRIVER” and “STEPPER DRIVER INTERFACE,” supporting its classification as a dedicated motion-control interface assembly.

Where It Is Used

The Lam Research 810-801237-021 can be relevant to semiconductor equipment involving precision mechanical positioning. Typical maintenance applications include:

• Semiconductor wafer-processing equipment
• Plasma processing systems
• Stepper-driven mechanisms
• Motion-control assemblies
• Lam Research Kiyo C Series equipment
• Equipment refurbishment
• OEM spare-parts replacement
• Preventive maintenance programs

A supplier specifically identifies this PCBA as being found on Kiyo C Series systems, although exact machine compatibility should always be confirmed from the equipment serial number and configuration.

Replacement Considerations

The 810-801237-021 is a specialized semiconductor-equipment spare part. Current industry records show examples of Rev B and Rev C boards, as well as new, used, and parts-only conditions.

Therefore, buyers should confirm:

• Exact OEM part number
• Board revision
• Equipment compatibility
• Physical condition
• Testing status
• Included components or accessories

We supply Lam Research 810-801237-021 Stepper Driver Interface PCB assemblies for semiconductor equipment maintenance, repair, and replacement requirements. Availability, revision, condition, and testing status can be confirmed according to your specific application.
