Product Characteristics
1. Signal Integrity-Centric Design
Controlled Impedance: This is the most critical characteristic. The characteristic impedance of PCB traces is strictly controlled to a target value (e.g., 50Ω single-ended, 100Ω differential) through precise calculation of trace width, thickness, dielectric height, and dielectric constant to minimize signal reflections.
Low Signal Loss: Use of special Low-Loss or Very-Low-Loss high-speed laminate materials with a lower dissipation factor, significantly reducing signal attenuation and distortion over long transmission distances.
Continuous Return Path: Providing complete, unbroken reference planes (usually ground planes) for all high-speed signals ensures a clear, low-inductance return path for signal currents, which is fundamental for controlling EMI and ensuring signal quality.
2. Sophisticated Structure and Manufacturing
High-Density Interconnect (HDI): Employs HDI technology, including microvias, blind vias, and buried vias, to achieve more complex routing and higher component density while reducing the parasitic effects of vias.
Strict Routing Rules:
Length Matching: Strict length matching for differential pairs and parallel bus signals to eliminate skew and ensure synchronous arrival.
3W Rule/Spacing Control: Ensures sufficient spacing between traces to reduce crosstalk.
Back-Drilling: Used to remove the unused metallized portion of through-hole vias (stubs). These stubs act like antennas, causing signal reflections that severely degrade high-speed signal quality.
3. Superior Power Integrity
Multilayer Stack-up Design: Incorporates dedicated power and ground planes to form a low-impedance Power Distribution Network (PDN), providing stable and clean voltage to high-speed chips.
Adequate Decoupling: Strategic placement of decoupling capacitors of various values around critical ICs to meet the high-frequency current demands generated during operation and suppress power supply noise.
4. Excellent Thermal Management and Reliability
Effective Heat Dissipation: High-speed chips consume significant power. The multilayer structure facilitates heat conduction and dissipation through inner-layer copper planes and thermal vias.
High-Reliability Materials: Often uses high-performance substrates with higher glass transition temperature and better thermal stability to withstand demanding environments.
5. Electromagnetic Compatibility (EMC) Design
Embedded Shielding: Isolates sensitive signals via ground via fences or shields to suppress electromagnetic interference.
Optimized Layout: Reduces current loop areas through component placement and layer stack-up design, thereby lowering EMI radiation.
