Applicable Processes: Polysilicon etching, dielectric etching, metal etching, photoresist ashing treatment
Downstream Scenarios: Logic chip manufacturing, NAND memory chip production, MEMS device processing, power semiconductor wafer processing
Usage Scenarios: Daily spare parts replacement, faulty board replacement, equipment disassembly maintenance, and second-hand equipment renovation projects in FAB production lines
6. Working Principle
The 810‑370141‑00 ASSY PCB board is inserted into the VME chassis slot of the equipment, with power supply and bus docking completed by the chassis backplane. The equipment main control unit issues control commands to the board card through the backplane bus. The internal logic chip of the board parses the commands and drives the corresponding relay array to complete loop connection or disconnection, so as to control external devices such as solenoid valves and safety interlock loops.
Meanwhile, the board continuously collects status signals from various on-site sensors and limit switches, converts them into bus signals and feeds them back to the equipment main control system. When interlock conditions are not met or loop abnormalities occur, the board immediately reports fault status, and the machine triggers shutdown protection to avoid process accidents, realizing a closed loop of control command issuance, on-site status collection and abnormal status reporting.
7. Product Comparison
Belonging to the Lam Research 810-prefix PCB board series, different part numbers have obvious differences in hardware layout, relay channel quantity and bus logic:
- 810‑370141‑00 focuses on multi-channel relay switch quantity control, mainly responsible for interlock and peripheral loop switching
- Other boards in the same series focus on analog quantity acquisition for temperature and pressure analog signal conversion, while some are dedicated to RF monitoring and gas panel signal processing
- All adopt European plug-in hardware appearance with high similarity, but cannot be directly interchanged due to different on-board component configurations
- REV revision versions have fine-tuned component layouts and resistance-capacitance parameters; old-version hardware cannot be directly used on high-version BOM machines, otherwise startup failures and alarms will occur
- Compared with discrete wiring solutions, 810‑370141‑00 integrated PCB assembly simplifies overall machine wiring and greatly improves fault positioning efficiency
8. Supporting Products
This PCB board is installed in the supporting equipment VME chassis, and the key matching components are as follows (version matching is mandatory):
- Complete Equipment: Lam Research TCP9400, Lam Research 2300 series etching equipment
- Chassis Backplane: 810‑0170xx‑0xx series VME backplane
- Main Control CPU Board: 810‑017031‑004 ADIO PCB Board
- Power Module: 810‑063892‑001 chassis power filter assembly
- Interconnection Cables: Internal multi-core interlock wiring and cavity status acquisition cables
Note: The 810‑370141‑00 board must match the versions of the above supporting boards and backplanes. Single board version correctness cannot avoid communication errors caused by mismatched auxiliary components.

10. FAQ
Q1: Can 810‑370141‑00 directly replace board cards of different REV versions?
A: No. REV hardware revisions involve adjustments of component parameters and operating logic. Machine BOM list verification is required before replacement. Version mismatch will cause interlock errors and board communication failures.
Q2: What machine alarms will be triggered by faulty 810‑370141‑00 boards?
A: Common faults include interlock loop errors, DO output no response, partial solenoid valve inaction, and abnormal point status reading by the main controller, which may trigger machine process startup prohibition in severe cases.
Q3: Does the 810‑370141‑00 PCB support hot-swap?
A: The hardware structure supports chassis hot-swap. However, per semiconductor production line specifications, it is recommended to power off the chassis partition before plugging and unplugging to prevent backplane surge voltage from damaging board chips.
Q4: What information is required for purchasing 810‑370141‑00?
A: Provide the complete part number 810‑370141‑00, board REV revision version, corresponding machine model and machine BOM fragments to confirm compatibility.
Q5: What inspections should be performed before installing new spare parts?
A: First verify the label part number and REV version, conduct static relay on-off testing. If conditions permit, perform chassis power-on simulation testing to confirm all channels work normally before installing on production machines.
Q6: What wafer size machines is 810‑370141‑00 applicable to?
A: Compatible with 200mm and 300mm Lam Research dry etching equipment. The final compatibility judgment shall be subject to the machine BOM list.
Q7: What is the general delivery cycle?
A: In-stock products can be delivered quickly; out-of-stock products require transfer and ordering with real-time inventory cycle confirmation. Priority ordering is available for emergency maintenance projects.
