Applications & Industry Context

In many industrial and semiconductor control systems, VME (Versa Module Europa) remains a backbone architecture for modular electronics—connecting CPU boards, I/O boards, instrumentation modules, and interface cards on a common backplane. However, VME backplanes often require breakout boards to route, buffer, distribute, or isolate signals from the bus to specific modules or peripheral wiring. That’s where LAM 810-800082-043 comes in: it’s a VME breakout / interface board used in LAM tool electronics to manage signal connectivity.

In practice, when engineers build or maintain LAM tool control cabinets (plasma tools, etchers, deposition systems), they mount the 810-800082-043 board to distribute VME signals (address lines, data lines, control strobes) to downstream modules or interface harnesses. In cases where modules must be moved, upgraded, or rewired, a functioning breakout board reduces complexity and improves signal integrity.

In one catalog, the module is flagged as discontinued, but still offered by parts houses as 100% new or used stock with a 12-month warranty. Another supplier (XiongBa) offers it under “VME Breakout PCBA” with 365-day warranty.

Because VME signal integrity is sensitive (timing, impedance, crosstalk), a well‐designed breakout board is critical to maintain bus timing and prevent data errors, especially in high-speed environments or in systems with many modules.

Product Role & System Fit

In the system, 810-800082-043 acts as an interface / signal breakout board connected to the VME backplane. Its main responsibilities include:

• Routing VME signals (address, data, control lines) from the backplane to peripheral connectors or modules.
• Providing isolation, buffering or protection between the VME bus and external wiring or module inputs/outputs.
• Supporting indexing or motion control when used in the “indexer interface” context — routing signals for axis indexing or synchronization. SaulControl labels the module “PCB Indexer Interface” for use with LAM 810-801237-021. saulcontrol
• Physical dimension constraints — it’s relatively compact and light, so it can be mounted inside module shelves or electronics cabinets without imposing large space or weight penalties.

In many LAM tool architectures, each slot in a VME chassis may connect to breakout modules rather than direct cabling, especially in systems where different modules require different wiring. The 810-800082-043 allows modular signal branching, easier maintenance, and clearer wiring topology.

When designing or replacing tool electronics, it’s essential to match the board’s pinout, connector layout, signal mapping, and any buffering logic to the original configuration—any mismatch can lead to module errors, bus conflicts, or signal corruption.

Technical Features & Benefits

Here’s what we can deduce about 810-800082-043, gleaning from source listings and engineering norms:

• VME Breakout / Bus Interface: eBay explicitly shows the part labeled as “VME breakout board.”
• Indexer Interface Variant: SaulControl’s listing calls it “PCB Indexer Interface” and gives external dimensions 163 × 38 × 58 mm, weight ~0.4 kg.
• Surplus / OEM Stock: J316Gallery lists a pre-owned “PCB, VME Breakout 810-800082-043.”
• Warranty / Availability: XiongBa and DCS-PLC listings describe it as discontinued but still offered with 1-year or 365-day warranties.
• Signal Integrity Design: Although internal design is not publicly disclosed, a VME breakout board must preserve controlled impedance, minimal delay skew, and protection (ESD, buffering) to maintain reliable bus performance.

From a benefits perspective:

• Using a breakout board like 810-800082-043 simplifies wiring and module replacement in complex control racks.
• It isolates the VME bus from peripheral wiring faults—i.e. faulty module wiring is less likely to damage the backplane.
• In the indexer interface role, it centralizes motion/axis signals for synchronization, reducing wiring complexity and improving maintenance clarity.
• Modular design ensures that if the board fails, replacing it restores functionality for multiple modules.

Technical Specifications Table (Inferred & Collated)

Below is a summary table based on public data and typical expectations. Many fields must be confirmed with OEM or internal tool documentation.

Because this is a bus / breakout module, electrical details (trace impedance, signal delay, buffer strength, isolation voltage) are not publicly disclosed but must be reviewed in internal tool drawings or vendor datasheets.

Installation & Maintenance Insights

Here are recommended practices and caveats when working with 810-800082-043:

• Proper insertion and alignment: Ensure the board seats fully in the VME chassis connector and any breakout connectors line up cleanly. Partial insertion can lead to signal errors, address conflicts, or bus failures.
• Power-off swapping: Unless the system explicitly supports hot-swap of VME modules, power down the VME backplane before removing or inserting the breakout board to avoid damaging signals or modules.
• Cable routing & shielding: Use shielded wiring for breakout signals. Keep field cables well-separated from power or noisy lines to minimize crosstalk.
• Signal integrity checks: After installation, validate VME bus communication (read/write, module enumeration) and check for bus errors, CRC faults, or timing anomalies.
• Spare board strategy: Maintain a verified working spare 810-800082-043 board. Because it is a central bus breakout, swapping the board often restores multiple module connections at once.
• Inspect connectors and contacts periodically: Contact plating, alignment, or oxidation can degrade over time, especially in high-vibration environments.
• Labeling and documentation: Record which module slot each breakout goes to, and any unique signal routing. When replaced, match the wiring to the original layout.
• Environmental control: Ensure the VME chassis / electronics cabinet is temperature-controlled, free from excessive dust or humidity, as signal boards are sensitive.
• Edge protection / buffer logic: If the board contains buffers, ensure that replacement parts use compatible logic levels and buffering designs.

In field experience, many communication or module-failure faults in VME systems are traced back to faulty breakout boards — swapping a known-good breakout board can eliminate a wide range of downstream faults quickly.
