How do you calculate PCB trace width?
Formulas Used
Then, the Width is calculated: Width[mils] = Area[mils²] / ( Thickness[oz] * 1.378[mils/oz] )
What is normal PCB trace width?
Trace widths are often measured in mils, or thousands of an inch. A standard trace width for an ordinary signal (no special requirements) may be in the 7-12 mil range and be as long as a few inches, but there are many things that should be considered when defining the width and length of a trace.
What is the width of a 20a trace?
For a 20-A current and an aggressive temperature rise of 20°C, the specification recommends a trace with 700 square mils or 891 circular mils cross section. In 2-oz/sq ft copper, the nomograph calls out a trace that is 0.275 inches wide, while in 1-oz/sq ft copper, the trace is 0.550 inches wide.
How much current can a 10 mil trace carry?
Under the same temperature rise that is 10°C, a 10mil-trace with 1oz copper weight is capable of withstanding current of 1amp at most and we rest assured that a 50mil-trace is capable of withstanding current larger than 1amp.
