Specification caution: Public sources disagree substantially on electrical ratings, I/O count, dimensions and detailed circuit functions. One listing describes it as a VME analog-I/O board, while other records explicitly identify it as a motherboard/backplane assembly. Those conflicting claims should not be treated as verified OEM specifications.
Product Introduction
The Lam Research 810-800081-022 is a legacy VME PCB assembly identified with Lam Research etch equipment. The part appears in equipment-spare records as “PCB ASSY .V ME.ETCH”, placing it within the VME-based control architecture of older semiconductor processing platforms.
This is not a generic PLC I/O card that can be selected by bus type alone. The motherboard/backplane arrangement, installed VME boards, connector wiring and system revision all affect compatibility. A replacement should therefore be matched against the original board and the target Lam tool configuration rather than relying on the part number alone.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
Legacy Lam VME systems can be difficult to troubleshoot because a fault appearing as a processor, I/O or process-control problem may actually originate from the motherboard/backplane interconnect. Aging connectors, solder joints, bus traces and mating-board contacts can create intermittent failures that are difficult to reproduce outside the equipment.
Typical Applications
- Lam Research VME etch platforms using the corresponding architecture.
- Legacy semiconductor process equipment requiring replacement of the original VME motherboard assembly.
- System-level troubleshooting involving unstable communication between VME boards.
- Maintenance-spares inventory for older production tools where an exact replacement board is required.
Technical Pitfalls to Avoid
- Do not substitute 810-800081-018 automatically.
The 810-800081 family contains closely related boards, but similar numbering does not establish electrical or mechanical interchangeability. A current field reference specifically warns against substituting 810-800081-018 for 810-800081-022 without tool documentation confirming compatibility. - Confirm the board revision.
Rev. B is reported for 810-800081-022. Revision changes can affect connector population, routing, component selection or system compatibility, so the installed board should be photographed and compared before replacement. - Do not approve generic VME hardware as a substitute.
Although VME is the underlying architecture, Lam’s assembly is equipment-specific. A standard VME backplane with the same physical bus designation is not necessarily electrically equivalent. - Be skeptical of generic analog-I/O specifications.
One online listing describes 16 analog inputs and 16 analog outputs with 16-bit conversion, while another identifies the exact part as a motherboard. Without an OEM schematic or equipment drawing, those channel specifications should not be used for procurement.

Procurement Check
Before purchasing 810-800081-022, verify:
- Exact part number: 810-800081-022
- Assembly marking: PCB ASSY .V ME.ETCH
- Board revision, particularly Rev. B
- Lam Research equipment model
- VME chassis and installed card configuration
- Connector population and mating cables
- Physical board dimensions and mounting points
- Condition of VME connectors
- Evidence of previous component-level repair
- System revision and associated software/firmware
- Functional test under the target equipment configuration
Recommended procurement description:
Lam Research 810-800081-022, PCB ASSY .V ME.ETCH, VME Etch Motherboard/Backplane PCB Assembly, Rev. B — verify exact tool compatibility before replacement.
The conservative identification is intentional: the available evidence supports the VME Etch PCB assembly designation, but does not justify treating every published electrical specification as authoritative.
