Hi All
I have some problem on package resistance measurement. Take BGA for
example,
I used to make
some "open" samples,and "short"samples to get the capacitance and
inductance
information
within a certain frequency range(bellow 6GHz). But for resistance, skin
effect let the resistance
 increase nonlinear. How can I get the "resistance vs. frequency"
information from the VNA or TDR
 measurement method?Does someone can help me to solve this
question?Thanks!

Jack
