Introduction Ceramic substrate warpage is the invisible killer in the power module packaging process. Once warpage occurs, subsequent chip mounting and wire bonding stages are bound to encounter serious problems. A series of failures, such as solder joint voids, chip […]

Introduction Among numerous advanced ceramic products, ceramic substrates  offer excellent thermal conductivity and strong insulation, making them ideal for high-end chips and power modules. Considering ease of processing and cost, ceramic substrates are typically produced through tape casting. However, their
