Description
Product Overview
The LAM Research 810-495586-001 is an Interlock Board used in Lam Research semiconductor processing equipment. Available equipment-parts records identify this part specifically as a 4520XL Interlock Board PCB Card.
An interlock board is typically part of the equipment safety and control architecture. It helps monitor defined machine conditions and interlock states so that equipment operation can be permitted, inhibited, or interrupted according to the system logic.
This board is intended for maintenance and replacement applications where the existing system requires the same part number or a verified compatible revision.

Publicly available references identify the part as a 4520XL Interlock Board, but I could not verify reliable OEM documentation for the board’s complete electrical pinout, supply voltage, individual I/O count, connector assignment, or internal logic. Those specifications should therefore be confirmed against the equipment documentation and the revision of the physical board before installation.
Interlock Board Function
In semiconductor processing equipment, interlock circuitry is used to supervise conditions that must be satisfied before certain machine functions are allowed to operate.
Depending on the equipment architecture, an interlock system may be associated with conditions such as:
- Access or door status
- Equipment operating state
- Emergency-stop conditions
- Process subsystem readiness
- Hardware fault states
- Safety-related permissive signals
- Communication or control-system status
The exact signals handled by the 810-495586-001 should be confirmed from the corresponding 4520XL system documentation rather than assumed from the general term “interlock.”
Typical Applications
The 810-495586-001 is relevant to maintenance work involving Lam Research 4520XL equipment, particularly when an existing interlock PCB has failed or shows unstable operation.
Typical maintenance scenarios include:
- Replacement of a defective interlock board
- Troubleshooting machine interlock faults
- Restoration of equipment after PCB failure
- Preventive spare-parts stocking
- Semiconductor equipment refurbishment
- Backup inventory for production tools
- Board-level maintenance and system troubleshooting
Several independent equipment-parts records also list this exact part number as a 4520XL Interlock Board, supporting the equipment association.
Installation & Configuration
Before replacement, record the complete identification information from the original board, including:
- Part number
- Revision marking
- Serial number, if present
- Connector arrangement
- Jumper or switch positions
- Cable routing and connector orientation
Power should be removed according to the equipment manufacturer’s service procedure before removing or installing the PCB.
After installation, inspect all connectors and mounting points carefully. Verify that the replacement board has the same part number and an appropriate revision before returning the equipment to service.
A functional check should then be performed using the applicable Lam Research equipment maintenance procedure, including verification of the relevant interlock states and machine permissives.
Maintenance & Inspection
For a used industrial PCB, inspect the following areas before installation:
- PCB surface for contamination or corrosion
- Connectors for bent or damaged contacts
- Components for visible thermal damage
- Solder joints for cracking
- PCB mounting holes and hardware
- Labels and revision markings
- Evidence of previous repair or modification
For equipment that has been operating in a semiconductor manufacturing environment, contamination should receive particular attention. Do not clean the board with an unsuitable solvent or aggressive process that could damage components, connectors, or PCB coatings.
Replacement & Compatibility Notes
The safest identification method is the complete 810-495586-001 part number together with the board revision.
Do not assume that another Lam Research interlock board is a direct substitute simply because it has a similar appearance or a nearby part number. Lam Research equipment contains multiple interlock and control PCB assemblies, including other 810-series boards, and their functions are not necessarily interchangeable.
Before purchasing a replacement, compare:
- Complete part number
- Revision letter/number
- PCB layout
- Connector locations
- Mounting configuration
- Equipment model
- Existing board labeling
- System documentation
