Technical Specifications

• Signal Type: Multi‑channel digital I/O, analog voltage signal
• Interface Connectors: Multi‑channel D‑sub connectors, flat‑cable connectors, pin header terminals
• Operating Environment: Semiconductor clean‑room class 10‑100 compatible
• Compliance: SEMI S2 / S8 safety standard Function Features
• Signal buffering and isolation between different equipment sub‑systems
• Signal routing and distribution for gas manifold control and chamber monitoring
• Over‑voltage protection for input signal channels
• On‑board status indicator LEDs for signal‑channel diagnostic
• High‑density multi‑connector layout for internal‑cable harness connection Application Scenarios: Lam Research 2300, Kiyo, Versys series etch tools; dielectric etch, conductor etch process equipment internal signal interconnection board. Performance Parameters: High‑signal‑integrity transmission for low‑level analog signals; anti‑interference performance for plasma‑process electromagnetic noise; long‑term stability under clean‑room continuous‑operation condition. Material Composition: Multi‑layer FR‑4 printed‑circuit board; gold‑plated signal connectors; signal‑isolation optocoupler components; surface‑mount protection devices. Structural Characteristics: Large‑format custom‑shape PCB; multiple high‑density external‑cable connectors; internal backplane‑connection sockets; mechanical mounting holes for cabinet‑frame fixation. Working Principle: Receives multi‑source analog and digital signals from equipment sensors and control boards; implements signal isolation and surge‑protection; routes signals to corresponding target sub‑system connectors; realizes physical‑layer signal interconnection for distributed equipment control architecture. Installation Requirements: Install inside equipment cabinet with limited mechanical‑stress on cable harness; tighten all connector fixing screws; avoid twisting and pulling of connected cables; ensure PCB surface free‑of‑process‑particle contamination. Usage Notes: Strict static‑electric‑discharge protection during handling; match cable harness part‑number with board interface definition; do not operate board with missing protective components; avoid exposure to corrosive process‑gas residues.
