2.3.1. Power Traces Routing

The width of power traces and vias (holes) through layers should meet the requirements of
current flowing:
• Traces of 1 mm wide should be able to carry the current of up to 1 A.
A 0.25 mm via on a 0.5 mm pad should be able to carry the current of up to 500 mA.
•
If copper foil is laid, please make sure that the width of each power trace is constant
•
along their length, with no bottlenecks due to other traces or vias.
