Description
📋 Product Overview
The LAM 810-495659-306 Rev.A is a PCB assembly identified for the BICEP II ESC DC-Probe power supply function in Lam Research semiconductor processing equipment.
The part-number family is consistently associated with BICEP/BICEP II electrostatic-chuck power-supply hardware. Related listings identify 810-495659-304 as a BICEP ESC power supply, while 810-495659-307 and 810-495659-308 are also identified as BICEP II DC-Probe power-supply assemblies. This makes the 810-495659-306 a specialized equipment-level power-control PCB rather than a general-purpose industrial power supply.

🔌 Operating Function
In a semiconductor process tool, an electrostatic chuck (ESC) is used to hold the wafer during processing. The associated power electronics must provide controlled electrical conditions to the chuck while also supporting monitoring and process-control functions.
The 810-495659-306 is identified specifically as a PWR SPLY ESC BICEP II DC-PROBE assembly. Its role is therefore associated with the power-supply portion of the BICEP II ESC/DC-Probe architecture.
A simplified system relationship can be represented as:
Lam Research Control System → ESC Power-Supply Assembly → BICEP II ESC / DC-Probe System → Wafer Processing Chamber
Because this is an equipment-specific assembly, the exact signal paths, voltage levels, protection circuits, and external connections should be determined from the corresponding Lam Research equipment documentation rather than assumed from the part number alone.
🔧 Installation & Configuration
This PCB should be treated as a system-specific replacement component. Before installation:
- Confirm the complete part number: 810-495659-306.
- Verify the board revision is Rev.A.
- Compare the replacement board with the original board.
- Check all connectors for bent pins, contamination, or oxidation.
- Inspect the PCB for cracked components or signs of overheating.
- Confirm the board belongs to the same BICEP II equipment configuration.
- Record cable and connector positions before removal of the original board.
- Install the board using appropriate ESD protection.
- Verify chassis grounding and mounting hardware.
- Perform system-level checks before enabling the ESC.
- Confirm DC-Probe and ESC-related monitoring functions.
- Run the equipment’s normal qualification or chamber verification procedure.
Do not apply external power to the board simply to determine its output characteristics. The correct test conditions depend on the Lam Research equipment architecture.
🧰 Maintenance Recommendations
For a used spare PCB of this type, inspection should focus on both the electronics and its operating environment.
Before installation
- Inspect the PCB for contamination.
- Check connectors and terminals.
- Look for burnt components or discoloration.
- Check solder joints for visible cracking.
- Inspect mounting holes and hardware.
- Verify the revision marking.
During equipment operation
Monitor for:
- ESC-related power faults
- DC-Probe errors
- Abnormal process behavior
- Repeated power-supply alarms
- Overtemperature indications
- Intermittent connector faults
Storage
Keep the PCB in an ESD-safe bag or container. Store it in a clean, dry environment and avoid exposure to conductive dust or process chemicals.
