Introduction Modern vehicles rely on hundreds of sensors to monitor engine performance, battery systems, emissions, braking, steering, and driver assistance functions. As automotive electronics continue to evolve toward electrification, autonomous driving, and intelligent control, sensor reliability has become more critical

Introduction Ceramic substrate warpage is one of the most common flatness issues in power electronics packaging. A substrate may pass incoming inspection, yet excessive warpage can still develop during reflow soldering or long-term service. Warpage behavior is closely related to

Engineering Selection of Al₂O₃, AlN, and Si₃N₄ Substrates Selecting a ceramic substrate for power modules is rarely a material-property exercise alone. Thermal performance, reliability, and cost must all be considered at the system level. They provide electrical insulation between the

Introduction With the widespread adoption of 800V high-voltage platforms and SiC power devices, electric vehicle (EV) power modules are facing higher thermal loads, more stringent thermal cycling, and higher reliability requirements. Traditional alumina (Al2O3) substrates are still widely used due

Introduction What is a ceramic substrate? A ceramic substrate provides electrical insulation and heat dissipation in electronic circuits that require both functions. Engineers commonly use ceramic substrates in power modules and semiconductor packaging where thermal stability and reliability are critical.
