Trace Width vs Current in PCB Design

This article explores the key factors influencing trace width, provides practical guidelines, and highlights best practices for selecting the correct dimensions based on current-carrying demands in modern PCB design. Traces on a Printed Circuit Board (PCB) Introduction PCB trace width refers to the physical width of the copper pathways on a printed circuit board that carries electrical current. It is an essential design parameter because trace width directly impacts how much current a trace can safely carry without overheating or failing. If a trace is too narrow for the current flowing through it, the higher electrical resistance of the trace will cause excessive Joule Heating (I²R losses), leading to heat buildup. This can result […]
