Using VIA in PAD? What you need to know – Guidelines, dimensions and more …

What is the minimum size of VIA and VIA-in-PAD which I can use in my board? What kind of VIA in PAD I should choose? How much is it going to cost? Everything important about the limits and recommendations of VIAs and VIAs in PAD.

Thank you very much to Mike and Exception PCB.
