Compute the resistance of an 8 mil wide copper conductor with a length of
120mm
and a copper thickness of 70 um. Assume the temperature is
25\deg C
. Solve graphically the inductance of two parallel tracks spaced
1.5mm
. Conductor width is
0.3mm
with a thickness of
35um
. Calculate the supply and ground width for a TTL circuit with a maximum signal current of
0.01A
. Assume that the thickness of the copper is
(1)/(2)oz
per square foot.
