Hi guys,
I have a question about CPWG.
Some details: I use FR4 [ε=4.5, H[pcb height] = 32mil, T[copper] = 1.41mil=1oz.
I am using Linecalc or AppCad and the results: w=21mil, g[gap]=6mil
But I readied that when working with CPWG must keep for two conditions:
1) g/T>1
2) H/(w+2g)>1
In another place I see that they want H/(w+2g)<=10
With second condition I can live but the first condition make me a little problem.
What I suppose to do???
TNX a lot
David
