Which outcome occurs when a PCB trace experiences excessive current density, creating high electron flow?

💡 Explanation

Electromigration weakens the trace because the increased momentum transfer from electrons to metal ions causes displacement via momentum transfer; therefore, material is preferentially displaced, reducing cross-sectional area, rather than creating heating improving conductivity because atoms diffuse.
