← ScienceWhich outcome occurs when parasitic capacitance forms between PCB traces carrying high-frequency signals?
A)Signal reflections due to impedance mismatch✓
B)Increased power consumption from dielectric breakdown
C)Reduced thermal conductivity along the trace
D)Higher resistance from skin effect reduction
💡 Explanation
When parasitic capacitance is present, it introduces impedance discontinuities because capacitance and inductance influence signal propagation, leading to reflections at impedance mismatches. Therefore, signal reflections occur, rather than dielectric breakdown, thermal conductivity changes, or resistance changes, which depend on other factors.
