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 электронные компоненты. For this 4-layer board:
- Передача сигнала: Signal traces on the top and bottom layers carry various sensor signals, сигналы управления, and data communication signals. The 0.1mm precision trace width/spacing ensures высокоскоростные сигналы travel along the shortest possible paths.
- Power Distribution: The inner power layer (Слой 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 (Слой 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.
- Контроль импеданса: By precisely controlling trace width, Диэлектрическая толщина, and dielectric constant (Dk=4.3–4.6 @ 1GHz), the design achieves controlled characteristic impedance (например, 50Ом несимметричный, 100Ом дифференциал), обеспечение целостности сигнала.
