Product Introduction
LAM Research 810-048219-015 Pulse Sample-and-Hold Board
The LAM Research 810-048219-015 is a pulse sample-and-hold circuit board assembly with synchronization output. Its listed assembly description identifies two key functions: capturing pulse-related signals and providing a synchronization signal to associated equipment electronics. It is intended for a specific semiconductor equipment architecture rather than general-purpose control applications.
810-048219-015
For maintenance teams, correct identification is essential because similar-looking LAM circuit boards can serve different signal-processing or control roles. Verify the board revision, connector layout, installed slot, and equipment configuration before replacement. Sampling performance and sync-output behavior should be checked against the applicable equipment service procedure.
Application Scenarios & Field Pitfalls
This board may be used in semiconductor process equipment where pulse signals need to be captured and held for downstream measurement or control, with a synchronization output coordinating related electronics. A failed or mismatched board could affect signal acquisition or timing. However, the exact process tool and subsystem assignment for this part number have not been confirmed in the available documentation.
Potential application areas
- Pulse-signal acquisition within semiconductor equipment electronics.
- Sample-and-hold circuits used by process measurement subsystems.
- Synchronization between pulse-monitoring electronics and associated control circuits.
- Maintenance of legacy LAM Research equipment using the specified board assembly.
Engineer checks before installation
- Confirm the equipment association. Match 810-048219-015 against the machine BOM, assembly drawing, and original board label. Do not identify the correct slot from the part number alone.
- Inspect revision and connector details. Compare PCB revision, component layout, connector keying, and any revision markings. A similar part number does not prove electrical interchangeability.
- Check signal behavior after installation. Use the equipment’s approved diagnostic procedure to verify sample capture, hold behavior, and synchronization output. Do not apply external test signals without confirming the specified signal limits.
- Use appropriate handling precautions. Power down the equipment as required by the service procedure and use ESD protection. Avoid hot-swapping unless the equipment documentation explicitly permits it.
Related Products
These LAM Research part numbers are useful references when identifying related circuit-board assemblies. Their functions differ, and none should be treated as a direct substitute without OEM compatibility confirmation.
- 810-048219-004 — Listed as a pulse power sample-and-hold assembly. It is closely related by function, but the different suffix requires a drawing and revision comparison.
- 853-069793-007 — Identified as a sample-and-hold bias-pulse assembly. Its bias-pulse designation indicates a different assembly role; verify signal routing and equipment compatibility.
- 810-046015-010 — Listed as a VIOP III board assembly. It belongs to the broader equipment electronics category but has a different stated function.
- 810-099175-011 — Listed as a VIOP Phase III board. Relevant when identifying other LAM control electronics, not a confirmed alternative for pulse sample-and-hold duties.
- 810-068158-015 — Listed as a robot interface board assembly. It serves a different equipment subsystem and should not be confused with the pulse sample-and-hold board.
Procurement recommendation: Before ordering, request photographs of both sides of the board, its complete part-number label, revision markings, and connector area. Also obtain the host tool model and installed slot reference. These checks are more useful than relying on generic descriptions or unverified electrical specifications.
