Are thermal vias in your PCB designs actually providing the heat management benefits you think they are? In this comprehensive analysis, Tech Consultant Zach Peterson explores the controversial I-Connect007 article that claims thermal vias are inefficient, examine real simulation data, and explore peer-reviewed research to uncover the truth about thermal via effectiveness.

Zach breaks down critical thermal management concepts, analyzes simulation results comparing different via configurations, and reveals why the right number and spacing of thermal vias matters more than simply adding as many as possible.
