Key Technical Specifications
Public, OEM-verifiable data on this board is limited to part identification and form factor — Lam doesn’t release electrical datasheets for internal spares like this to the open market. Here’s what’s confirmed:
- OEM Part Number: 810-072907-005
- FAB/Drawing Number: 710-072907-005
- Revision: A (confirm current rev against your tool’s BOM — later revs may exist)
- Board Type: Breakout PCB (signal/interconnect distribution board)
- Subsystem: VTM module
- Manufacturer: Lam Research Corporation
- Market Classification: Legacy/spare part, semiconductor fab equipment
- Typical Condition on Market: Used, Refurbished, or New Open Box (no factory-sealed new stock observed)
❗ What’s not publicly verifiable: Voltage rails, current draw, connector pinouts, and physical dimensions are not published outside Lam’s internal documentation. Do not accept spec sheets from third-party resellers as gospel — cross-check against your tool’s actual drawing package or your Lam CE contact before purchase or install.
Product Introduction
The Lam Research 810-072907-005 is a breakout PCB assembly for the VTM subsystem, built to FAB drawing 710-072907-005 Rev A. It routes signal and interconnect lines between the VTM module and adjacent control hardware inside the tool’s electronics rack.
This part shows up almost exclusively in the surplus and refurbished spare parts market — it’s not something Lam sells as new-manufacture stock through normal channels. Buyers pick it up as a direct swap for a failed or aging VTM breakout board rather than as new capital equipment, which is why condition and test history matter more here than a spec sheet comparison.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| VTM module reports comm loss or signal dropout | Faulty breakout board connector/trace | ✅ High | Visually inspect connector pins for bent/corroded contacts; check continuity with a DMM | If connectors and traces test bad, replace the breakout board |
| No power at VTM downstream connectors | Upstream power supply or fuse failure | ❌ Low | Measure supply voltage at the source before the breakout board | Rule out the PSU and fusing first — breakout boards are passive interconnects, not power generators |
| Intermittent VTM readings | Loose ribbon cable or connector seating | ❌ Low | Reseat all cables at both ends; inspect for pin damage | Usually a cabling/connector issue, not the board itself |
| Physical damage (cracked traces, burn marks, corrosion) | Board-level fault or ESD event | ✅ High | Visual inspection under good lighting; check for discoloration around components | Replace the board — repair on a legacy breakout PCB is rarely cost-effective |
| Tool fails VTM subsystem self-test | Could be board, module, or firmware/config mismatch | ⚠️ Medium | Check error/diagnostic codes in the tool’s controller log first | Isolate to the VTM board only after ruling out the module and controller settings |
If you’re stuck at 3 AM staring at a fault code, get the tool’s diagnostic log and photos of the board’s connectors and any visible damage before you order — a lot of “bad board” calls turn out to be a bent pin or a loose ribbon cable.

Frequently Asked Questions (FAQ)
Is this a direct drop-in replacement for my tool?
Match the FAB number (710-072907-005) and revision letter against what’s currently installed before you order. Lam revises these boards over the life of a tool platform, and a rev mismatch can mean a physically different connector layout or an incompatible trace routing. If your current board’s rev isn’t A, ask the seller directly — don’t assume it’s interchangeable.
Why can’t I find a datasheet with the electrical specs for this board?
Because Lam doesn’t publish one for the open market. This is an internal OEM interconnect board, not a catalog component. The specs that matter — supply voltages, signal types, connector pinouts — live in Lam’s internal drawing package tied to your specific tool configuration. If you need those numbers, they come from your tool’s documentation or a Lam field service contact, not from a reseller’s product page.
New, refurbished, or used — what’s actually available?
All three show up in the market at different times, and pricing swings hard depending on condition — historical sales on this part number range from around 500 for untested pulls to over 5,000 for New Open Box units. “New Open Box” typically means old excess Lam inventory that was never installed, not current production. Ask the seller for the specific condition grade and whether it’s been function tested before you commit.
Will swapping this board wipe out my tool’s configuration or calibration?
A breakout board itself is a passive interconnect — it doesn’t hold firmware or configuration data. That said, always document your current cabling and connector orientation with photos before you pull the old board. It’s a five-minute step that saves you a troubleshooting session later if anything gets reseated wrong.
Can I test this board before installing it in a production tool?
Ideally yes — bench-test continuity and connector integrity before it goes anywhere near a live chamber. Since there’s no factory functional test spec published for this part, your best bet is comparing it side-by-side against a known-good board of the same rev, or having your equipment team run it through the tool’s own subsystem self-test in a controlled, non-production state first.
Why is this part more expensive than I expected for a “just a breakout board”?
Legacy semiconductor fab spares carry a premium because Lam doesn’t remanufacture them and NOS (new old stock) supply is fixed. Once existing surplus dries up, pricing on parts like this tends to climb — the market data shows real spread over time, from 500 sold-lots up to 5,500+ listings, which tells you supply is thin and inconsistent rather than there being a “standard” price.
Do you have test videos or photos of the actual unit before I buy?
That’s a fair ask for any used industrial board — request test videos, continuity check results, and close-up photos of the connectors and solder side before you commit, especially on a part in this price range. Any legitimate seller should be able to provide that.
