So I started looking at trace widths and looking at the currents I draw which are less than 100ma.
I have always just been using Egales default of .40 but I’m starting to understand that its way over what I need. Thats at 1oz, it looks like with that kind of thickness I would be good for up to 1.5 amps.
I was reading some of what you guys recommend and it looks like .25 might be perfect for me. A all round good number unless I’m driving something power hungry I would never need to go over it.
Then on my power and ground sides I can run .40 just to be extra safe even though I draw around 100ma through them.
Does this sound right.
Using the attached I was able to see that at 1oz with a 1amp current draw that it still says .04 is fine for track width. But the lowest the fab house I use goes to is .1524.
So using the same table I see that .1524 would be good for up to 2amps…
Am I reading all this correctly if so then I have been way way over doing it on the traces.
