High-Speed PCB
High-Speed PCBs are specialized circuit boards designed specifically for processing high-speed digital signals above the gigahertz level. Their core goal is to ensure signal integrity by precisely controlling impedance and reducing signal loss and latency. These boards are based on a variety of substrates, including FR-4, high-frequency materials, ceramics, and metal substrates. They possess excellent electrical performance and thermal management capabilities, and their structures range from single-layer to complex designs up to 32 layers. They also support special processes such as rigid-flex. With ultra-fine lines and spacing of 0.075mm, 10:1 high aspect ratio drilling technology, and various surface treatments such as nickel-immersion gold and OSP, they can effectively address attenuation and crosstalk issues in high-frequency signal transmission. They are primarily used in core areas such as data center servers, high-end routers, artificial intelligence acceleration cards, and supercomputers, which have stringent requirements for data transmission speed and stability.
