The copper grain size is an important property of Direct Bonded Copper (DBC) substrates. Variations in the copper grain size cannot be fully excluded, but large variations may affect the subsequent assembly processes or the performance of DBC substrates. Module manufacturers can rely on the experience and competence of Rogers' Power Electronics Solutions team to deliver substrates with a consistent grain size.

Who cares about flatness? Process and application engineers do! These are not flattering words as they truly know how critical it is to understand and control the shape of one’s substrate, base plate and heat sink in order to achieve the best possible production yield and module performance. In this blog, I want to share with you some information about flatness that you may wish to consider as you design or use power modules.

Design engineers are selecting Direct Bonded Copper (DBC) and Active Metal Brazed (AMB) substrates as circuit material for bare semiconductor chips in their power modules as they efficiently dissipate the waste heat from the semiconductors and increase the lifetime of the modules. In this blog, we explain the production process for power modules and highlight the most important characteristics of the substrates at each step of this assembly process.
