AI-generated Summary: Wire bonding damage occurs during the assembly of bare die or wafer IGBTs when improper bonding conditions cause defects such as misaligned bonds, chip surface scratches, or cracks. Excessive bonding stress can damage cells visibly or internally, affecting device performance and reliability. Evaluating bonding limits by adjusting power and force ensures optimal bonding strength without damage. Careful verification of bonding conditions improves yield and prevents failures like turn-off malfunctions caused by localized damage.

AI-generated Summary: Wafer testing for IGBT chips bridges the gap between wafer-level and module-level testing by applying higher test currents closer to module conditions, improving overall module quality. Key failure modes include gate failure, detected through high-voltage DC screening to identify oxide defects, and SOA failure, identified via AC switching tests to detect transient current concentration and latch-up failures. Gate screening applies stress beyond normal operation to reduce early failures and ensure long-term reliability. L-load AC screening rejects chips prone to latch-up by simulating switching conditions, enhancing yield and reducing costs in module manufacturing.

AI-generated Summary: The TO-247plus package differs from the TO-247 mainly by including screw holes while maintaining similar external dimensions and pin pitch, allowing easy board design compatibility. Heat dissipation is critical for IGBTs due to power generation; proper mounting torque (20-100 N) ensures stable thermal contact without damaging the device. Applying thermal grease significantly improves heat conduction by reducing thermal resistance by 1.8 times. The TO-247plus package offers better heat dissipation than TO-247 due to a larger chip mounting frame. Proper device handling during heatsink mounting prevents damage such as resin chipping or internal cracking.

AI-generated Summary: When connecting IGBTs in parallel, current unbalance occurs due to differences in VCE(sat) and parasitic resistances in the wiring and board. This unbalance affects device loss and switching behavior. Minimizing VCE(sat) variation by using devices from the same production lot and designing symmetrical layouts reduces unbalance. Gate driver emitter-sense wiring must also be symmetrical to ensure equal gate voltages. Temperature dependence of VCE(sat) influences current sharing, with positive temperature dependence improving stability.
