Hello,
I have a few questions regarding thermal reliefs on vias and through holes.

Is thermal reliefs on through holes a standard practice? Generally
what percentage of total periphery  of the via/hole remains in contact
with the plane?

Is there any adverse effects from having thermal reliefs on a through
hole connector pins?

For standard through hole connectors like DIMM connectors, can I
assume that the number of power and GND pins are determined after
considering the effect of thermal relief on conducting area?

Thanking you all in advance,

MJA
