How Does PCB Trace Width Affect Current Capacity?
A wider trace can carry more current—but width is only one part of the equation. Every PCB trace width has resistance. As current increases, that resistance produces heat according to I²R. If the generated heat cannot dissipate effectively, the conductor temperature rises and can affect PCB reliability. That is why current capacity depends on more
