Finding Shorted Components on Printed Circuit Boards by Infrared-Based Direct Current Injection Method
This article explains how to find shorted components on PCB assemblies using infrared-based direct current injection, a nondestructive method that has several advantages over magnetic microscopy and voltage drop measurement techniques. An application example involving a power board failure is also provided.
