4 Tips in high-speed (>100MHz) high-density PCB design

by Marketing PCB HERO

4 Tips in high-speed (>100MHz) high-density PCB design

1. Control the continuity and matching of the trace characteristic impedance.
2. The trace space
3. Use blind/buried via to increase the area of the track.
4. Differential termination and common-mode termination can be reserved to mitigate the effects on timing and signal integrity.
