controlled impedance routing
Hi all ,
I have a doubt. With respect to below given stack up ,Can we implement Controlled impedance routing in the TOP LAYER?If No why? If yes is the normal formula
Z = 87/Sqr(εr+1.41) +ln(5.98h/0.8w+t)
t= thickness of cuppoer foil
w = width of trace
H - Height of dielectric
work? Also what will be h?
Stack Up:
Top Layer -------------------------------
Signal Layer -------------------------------
GND Layer -------------------------------

Bottom Layer ---------------------------------
