Power electronics is changing rapidly. New packaging technologies are facing a rise in chip temperatures as seen in such applications as EVs / HEVs. Electronics increasingly need longer lifetimes to function in harsh conditions, such as wind turbines. Power electronics based on SiC components need to handle faster switching in the face of higher temperatures. While beneficial, the challenge is that these changes produce considerable stress on power systems and, consequently, result in reliability problems.

Traditional power module designs were primarily based on Al2O3 or AlN ceramics. But the need for higher performance is leading designers to choose more advanced substrates. substrates with Si3N4 ceramics use the excellent bending strength, high fracture toughness, and good thermal conductivity of Si3N4 to build substrates that can handle a variety of today’s challenges.

In the following video, the Power Electronics Solutions team at Rogers takes a look at how to make the right substrate choices to support demanding applications.

VIDEO: 3 Steps to Select the Right DBC / AMB Ceramic Substrate for Your Application

In this video, Olivier Mathieu, Product Innovation Manager, discusses how to use the latest substrates in power electronics designs. He walks us through: (a) How to select the right ceramic thickness and its influence on basic isolation voltage, (b) How to select the right ceramic grade and its influence on heat removal, and (c) How to select the right copper thickness and its influence on functional isolation, ampacity, and heat removal.

  1. How do you become a supplier to your organization. After reviewing your company website, I felt compelled to reach out for assistance in becoming a supplier. LAI is a small, minority owned business with precision laser capabilities, we produce pre-forms for many large OEMs.

    Please advise the process to become a premier supplier for processing conductive adhesive films, RF laminates and many other products to Rogers Corporation.
    Thank you for your time and consideration.
