In electric vehicle traction inverters, High-Voltage On-Board Chargers (OBC), and industrial power distribution modules, silicon carbide (SiC) MOSFETs and IGBTs run under high-voltage environments. Under extreme mechanical mounting torque, standard compliant pads are highly vulnerable to micro-puncture by metallic burrs remaining on heatsinks, triggering terminal catastrophic shorts. Polyimide-Silicone Composite Thermal Pads overcome this engineering challenge […]
