Yesterday, NASA announced yet another historic moment on Mars: the landing of their most advanced explorer yet, the Perseverance Rover. After a 6-1/2 month long journey from Florida, the rover successfully touched down at the Jezero Crater at 3:55 pm EST.
In this edition we would like to answer a few frequently asked questions to benefit those new to the power electronics community and a refresher training for those experienced in the industry as well.

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.

In January of 2004, the Mars Opportunity Rover began its mission in the Meridiani Planum region of Mars after a 7 month long journey from its launch in Florida. Originally intended to collect data for 90 days and travel only 1000 meters, Opportunity persevered, completing its mission 15 years and 45 kilometers later.
In the world of electronics, heat can severely shorten the lifetime of a device. It is therefore necessary to move heat away from vital components such as chips, LEDs, and inverters to maintain optimal performance without shortening the lifetime. There are many different thermal management techniques that can be utilized by engineers depending on the devices heat density, space constraints and cost.

A data sheet is the main source of information for design engineers to understand the overall performance of a power module. It provides a wide variety of values and diagrams but detailed background explanations on each parameter are often missing. On the other hand, a test set up cannot cover all possible applications or operating conditions and the values can vary according to the user's particular application.

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.
