What is the smallest pad size I can use?

Hi,

I’m doing a very densely populated small SMD board and the size of the vias are the limiting factor for me.

Using the 20mil min drill size and the 8 mil traces it seems that 36mils is the smallest “supported” pad size.

What is the smallest that has worked for you?

Thanks C.

I think GP can do 15 mil drills. The vias on my current board are about 15mil drills with 30 mil total diameter, and GP made them okay (but I haven’t tested the boards yet :slight_smile: ).

Thanks silicOre,

I will give that a shot, it seems to make sense from what I can infer from the threads that talk about the DRC test specs.

Saving 6mils is a huge savings for me.

Good to know you have one of these in hand even if it still needs to be tested.

Kind Regards C.
