[PCB_FORUM] Re: Via inside SMD discrete..

It is better to route the signal across the cap than to route the cap and IC to the planes independently. When routing the cap send the trace from the IC into the cap pad from the opposite side as the trace exits the cap pad to go to the via. If possible, performance will be much improved by creating a V shape with the entry and exit traces as this will turn the trace parasitic inductances and resistances in your favor.

He seems to disagree with you.
