Hi,

According to the documentation, the via size hole is 6 mil.

I would like to know if I can use via size hole of 4 mil instead?

Hello,

Although 6 mil hole size is recommended, 4 mil hole size is fine as long as your fabrication house is able to do it.

Hi,

I have another question. Will 4 mil hole size affect the chip performance in any way?

Thanks

Hello,

I dont expect any the 4 mil hole size to have any significant effect on the performance.
