Technical Specifications:​ Power supply +5 V, +12 V, ±15 V dedicated multi-rail, 16-bit analog acquisition, analog and digital I/O, chamber sensor interfaces, impedance adjustment range 1 Ω to 2000 Ω, VSWR below 1.2:1, matching response below 100 ms, operating temperature -20°C to +60°C, storage temperature -40°C to +85°C, dimensions 100 mm × 80 mm × 35 mm, weight 0.25 kg.

Functional Features:​ Closed-loop adaptive matching, coordinated vacuum-variable and fixed capacitor control, isolated signal acquisition, RF noise filtering, overcurrent/over-temperature protection, fault diagnostics.

Performance Parameters:​ 16-bit ADC sampling, sub-100 ms dynamic matching response, stable low-reflection operation under changing plasma load.

Materials And Structure:​ Industrial high-grade PCB, SMT components, RF control circuitry, relay/driver stages for variable capacitors, shielded sections, plug-in control-cabinet format.

Working Principle:​ The board measures forward/reflected power and chamber impedance, computes matching commands, drives vacuum variable capacitors and fixed capacitor banks to minimize VSWR, and feeds process data to the tool controller.

Application Scenarios:​ Lam 2300, Exelan and Flex etch systems, RF matching for dielectric/conductor etching and related plasma processes.

Installation Requirements:​ Install in the specified control-cabinet slot, connect +5/+12/±15 V only, confirm capacitor-driver and sensor wiring, apply ESD handling, verify cooling airflow or specified cooling interface, align connector seating before power-up.

Usage Notes:​ This -003 revision is not interchangeable with 605-109114-004 24 VDC variants. Verify supply rails, RF grounding and matching calibration after replacement. Inspect capacitors, drivers and acquisition channels during preventive maintenance.
