PCB thermal hotspot map helps engineers find where heat concentrates before it becomes drift, derating, solder fatigue, or field failure. Instead of treating thermal review as a late-stage check, the map turns temperature into layout evidence: which packages, copper areas, vias, planes, and airflow routes carry the thermal load. For PCB engineers, the value is practical. A good map tells you where to add copper, when to use thermal vias, and whether airflow or enclosure assumptions are causing the problem. This guide explains what a PCB thermal hotspot map is, how it is created, how to read it, and how to turn the result into layout changes.
