Hello,Joerg said:No, I want to do two mouse clicks and read a nice little ohms value
if you want to get a nice and precise ohms value, you need to know not
only the exact shape of the ground plane and the location of the two
points, but you also should know the thickness of the ground plane.
Unfortunately, there are large tolerances for the copper thickness, a 35
µm layer may be anything between 45 and 30 µm, for galvanic copper even
between 60 and 25 µm. The thickness is even not constant over the whole
plane.
