I have a part i imported from manufactuerers part list and has the following layout: enter image description here

This is the layout pattern in it's datasheet: enter image description here

I had set DRC rules to have a min via hole size of 0.3mm and this is why this error pops up. Should i simply ignore this error? Is there a way such that i still get all other DRC errors but this one doesn't show up?

Or would you remove the min via size rule altogether?

The manufacturers I am considering for this PCB have the following on their website:

Your choices include

  • Change your minimum via diameter to 0.2 mm. Once you have 4 or 8 0.2-mm vias in your design, adding more won't change your cost much.

  • Add these vias to a class, and make a special rule for that class with a 0.2 mm minimum diameter.

  • Increase the via size to 0.3 mm, with some risk of solder wicking through them and starving the thermal pad connection of solder.

  • Ignore the errors.
