원천: Shengyi 기술 유한 회사, 주식회사. S1000H data sheet
S1000H laminate achieves aTd of 348°C, well above the peak temperature of lead-free reflow soldering (approximately 245–260°C), ensuring no material decomposition occurs during soldering. 그것은T288 heat resistance time ≥5 minutes (measured up to 20 분) means the material withstands 288°C for over 5 minutes without delamination. These thermal properties are critical formedical PCBs operating in demanding environments.
Layer Stackup and Impedance Control
이것4-layer medical device PCB uses a classic stackup configuration:
- 층 1 (맨 위): Signal layer
- 층 2 (내부 레이어 1): Solid ground plane (접지)
- 층 3 (내부 레이어 2): Power plane (힘)
- 층 4 (Bottom): Signal layer
이것 “신호-접지-전력-신호” stackup reduces loop inductance by approximately 30% and effectively suppresses electromagnetic interference (EMI), ensuring reliable transmission of sensitive analog signals and high-speed digital signals inmedical electronic devices.
High-Density Routing Design
- 최소 구멍 직경: 0.1mm – supports HDI-level design
- Minimum Trace Width/Spacing: 0.1mm/0.1mm (approximately 4mil/4mil)
- 동박 두께: 1oz/1oz/1oz/1oz (약 35μm) – equal copper distribution across all four layers
The 0.1mm trace width/spacing represents a high level of precision in PCB 제조. Combined with the 0.1mm minimum hole diameter, 이것 의료용 PCB supports high-density component packages (such as BGA and QFN), meeting the miniaturization and integration trends in medical device design.
Surface Finish – Immersion Silver
이것의료용 PCB 용도침수은 (IAg) 표면 마감, fully compliant withIPC-4553A Specification for Immersion Silver Plating for Printed Boards. Key advantages of immersion silver include:
- Nickel-free coating: Eliminates magnetic interference and signal issues caused by nickel layers
- High conductivity: Silver offers the best electrical conductivity among all metals
- Uniform thin deposition: Suitable for ultra-fine pitch layouts
- 우수한 납땜성: Reflow soldering wetting time typically under 2 초
- Wire bonding capability: Supports gold wire bonding required in medical devices
- ROHS 준수: Lead-free environmentally friendly process
Operating Principle and Signal Integrity
The core operating principle of a medical device PCB can be summarized as: providing mechanical support and electrical interconnection for 전자 구성 요소. For this 4-layer board:
- 신호 전송: Signal traces on the top and bottom layers carry various sensor signals, control signals, and data communication signals. The 0.1mm precision trace width/spacing ensures 고속 신호 travel along the shortest possible paths.
- 배전: The inner power layer (층 3) provides stable power distribution to all components on the PCB. The 1oz copper thickness ensures sufficient current-carrying capacity.
- Grounding and Shielding: The solid ground plane (층 2) provides a low-impedance return path for all signals and acts as an electromagnetic shield, preventing electromagnetic interference between different functional modules within the medical device.
- 임피던스 제어: By precisely controlling trace width, 유전체 두께, and dielectric constant (Dk=4.3–4.6 @ 1GHz), the design achieves controlled characteristic impedance (예를 들어, 50Ω 단일 종단, 100Ω 차동), 신호 무결성 보장.
