For Wide Bandgap Silicon Carbide and GaN High-Voltage and High-Current Known Good Die Applications
High-Power Known Good Die Test Contactor
cGator™ singulated power contactor is a top and bottom contacting solution for power Known Good Dies (KGD).
Cohu´s patent pending Volta-Flux™ MEMS probe architecture technology provides stable and low CRES for very challenging high-voltage and high-current requirements.
The gentle-touch feature reduces surface impacts to a minimum while providing a reliable contact force.
The Volta-Flux high-power density solution enables efficient die heat dissipation from top and bottom surface of the die under test.
MEMS probe technology enables smart stacking of pins to increase current carrying capability.
The cGator is designed to address the most common test parameters, for example:
- Off-state tests: BVDSS
- On-state tests: RDSon
- Unclamped Inductive load Switching / Avalanche tests
- Dynamic switching tests: Single pulse and double pulse inductive load switching
