Hello all,
I'm currently routing a project I made using eagle, but I'm worrying about the trace sizes I can use.
For DC power transport (I use a Myrra 240 - 5V transformer, with maximum of 900mA, which shall be largely sufficient) I use 10mil width and 12mil clearance traces.
For signal (basically the PCB I'm making is a SCART switch, so no much power is involved here, except perhaps for the 4 LEDs at the corners), I use only 2 mil (and 4 mil clearance, 5 mil via holes)
According to this web site, even 0.5 mil is large enough to transport up to 100 mA (again, the frequencies will be low, this is SCART), so I guess I'm OK by far.
By using default copper thickness in outer layers :
The site gives me this info :
But according to other threads I saw here and there, seems like I shall use 10mil thick (or 8 mils in certain conditions) instead.
So what are your thoughts about that ? I have nothing against 10 mil traces, but 2 mils would be a lot better for me as I have 8 SCART inputs, which can make up to 64 parallel traces onto the PCB, which makes a huge difference...
