← TechnologyWhich consequence results when impedance mismatches occur in a PCB circuit routing?
A)Signal reflection and power loss✓
B)Decreased electromigration in components
C)Enhanced thermal dissipation uniformity
D)Improved EMC shielding effectiveness
💡 Explanation
Signal reflection and power loss increases because transmission lines behave as discontinuities, therefore some of the signal reflects back to the source due to wave impedance changes, rather than continuing towards the designated load. This mismatch reduces power transfer efficiency.
