Which consequence results when thermal stress fractures epoxy-sealed electronic components?

A)Delamination reduces thermal dissipation efficiency
B)Passivation layer blocks ionic migration
C)Dopant diffusion creates localized shorts
D)Dielectric breakdown induces inductive heating

💡 Explanation

Fracturing weakens the epoxy reducing its adhesion; interfacial DEBONDING occurs because thermal cycling induces differential expansion. Therefore, delamination lowers thermal conductivity, rather than creating electrical shorts because mobile ions are immobilized and electrical conductivity is unaffected.
