Found it!!

"A good trace width for low current digital and analog signals is 0.010″.

Traces that carry significant current should be wider than signal traces. The table below gives rough guidelines of how wide to make a trace for a given amount of current.

0.010″ 0.3 Amps
0.015″ 0.4 Amps
0.020″ 0.7 Amps
0.025″ 1.0 Amps
0.050″ 2.0 Amps
0.100″ 4.0 Amps
0.150″ 6.0 Amps"
