DBC, an acronym for Direct Bonded Copper, is widely recognized as a premier substrate material for power modules in various industries. Its unique properties make it an ideal choice for ensuring efficient heat dissipation and reliable operation of electronic components.

The study presented in this paper delves into the thermal spreading behavior of DBC-based power modules. By understanding how heat is distributed and dissipated within these modules, engineers can develop more effective designs that optimize performance and extend the lifespan of electronic systems.

To enhance the thermal performance of DBC-based power modules, a comprehensive design guide is proposed. This guide focuses on the selection of optimized layer thickness and substrate size, two critical factors that significantly impact heat transfer and dissipation.

By carefully considering the layer thickness, engineers can balance the need for structural integrity with the requirements for efficient heat dissipation. Similarly, the substrate size plays a pivotal role in determining the overall thermal performance of the power module.
