Which outcome results when dielectric breakdown surpasses maximum E-field strength around a signal trace along a PCB during high frequency signal propagation?

💡 Explanation

Signal reflection and impedance mismatch occur because dielectric breakdown causes rapid energy dissipation via dielectric loss, rather than allowing continued propagation. Therefore, the signal attenuates and reflects, rather than continuing unaltered; the increased capacitance changes impedance along propagation path.
