Hello Gregg, 

You can place Via in pad, using a type VII via protection (Filled and capped). For balancing, place via on pad for both the pads of 0805.

Thanks and regards,

Renjith Varughese

Subject: [DC] Vias in pads

Hello,
It has been a number of years since I was active in the PCB design realm. I was asked a question yesterday about the possibility of placing vias inside a component pad. My first response was "no way", but then I thought maybe things have changed.

I have used vias in heatsink pads for thermal reasons, but this designer was asking about placing a signal via inside one pad of an 0805 resistor.
What are the guidelines these days?

Thanks,
Heather Gregg
