Fusing Currents in Traces - UltraCAD
When sufficient heat is applied to a copper trace (or indeed, any material) to melt the trace, there are two times that need to be considered.

If the trace is shorted, the reflection coefficient is –1 and there will be a 100% reflection of the opposite sign back toward the driver. If the line is terminated with a resistor whose value is the same as the characteristic impedance of the trace (Zo), the reflection coefficient …
