Predicting Fusing Time of Overloaded PCB Traces Can We Predict It At All? with Douglas Brooks and Johannes Adam

When Traces Melt:  Figures 1 and 2 (Note 1) illustrate traces on two different boards. Each figure illustrates the trace at the moment it fuses (melts) due to a significant current overload. The fusing mechanisms are clearly different. So what was different? Here is the first hint. Assume there is a current that is just …
