In EV inverters, solar converters, and industrial servo drives, TO-220 and TO-247 MOSFET/IGBT modules require simultaneously high thermal dissipation and thousand-volt dielectric isolation. Under high assembly clamping torque (0.8–1.2 N·m): Unreinforced TIMs: Suffer from lateral plastic flow, thinning out or puncturing over metal burrs. Dielectric Drop: Triggers catastrophic high-voltage arcing and electrical short circuits. Lixing […]
