probe pad size

It depends on the GSG on-wafer probe you are using mainly.

as for me, 80u*80u is OK

Re: GSG Probe Pad size

yes, I do think so.
and I think that you can find the minimum require value from the techfile of the probe producer.

large pad size eases measurement setting while brings about huge parasitice capacitance, so for me, the minimum possible value is just fine.
