uVia Optimization

Updated: Jan 14

Micro-vias are used in high-density, mixed-signal, and high-speed boards.

To drive high-speed signals through vias, especially micro-vias, the via size, antipads surrounding them, and return-path GND vias must be located very carefully. 

Having mentioned the above, an additional critical parameter affects "fine-tuning" via impedance.

This video exposes that parameter.

Keysight ADS SI tools were used for this Test Case.
