Wide Bandgap Power Devices Force New Die Attach Chemistry
Silicon carbide and gallium nitride devices in vehicle inverters, chargers, and industrial drives operate at junction temperatures and switching speeds that conventional epoxy die attach and standard solder cannot survive over a design life. Sintered silver and high-temperature materials handle it and cost several times more, which raises material value per device sharply. Thermal conductivity requirements around eight watts per metre kelvin are now routine where two would once have sufficed. Suppliers with sintering process knowledge and equipment partnerships hold positions that formulation capability alone cannot reach, since the application process matters as much as the material.
