What should PCB trace width be?
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.
How much current can a 0.5 mm trace carry?
External PCB Trace Max Current

What is PCB trace?
A PCB trace or PCB track is a copper conductor on the PCB that conducts signals on the surface of the PCB. It is the flat, narrow portion of the copper foil that is left behind after etching. The electricity that flows through the copper traces generates a significant amount of heat.
How do I trace a PCB connection?
Use the free multimeter’s probe to touch a single spot on the board. Then using your finger with the foil move it over the components touching the soldered parts. Thus you will cover more area quicker and when you hear the multimeter beeping – you have found your track on the PCB.
