curamik® electronics, which is part of Rogers’ Power Electronics business, will be presenting at the eCarTech Conference in Munich on October 23-25,
2012.  This conference takes place during  the 4th International Fair for Electric- and Hybrid-Mobility for electric vehicles. curamik recently released a new silicon nitride (Si3N4) ceramic substrate that can significantly extend the life span of power electronic modules, and will be presenting this product at the conference.

Manfred Götz, Product Marketing Manager from curamik will be giving a presentation about this new ceramic substrate on Thursday, October 25th at 3:00 PM:

“How silicon substrate can increase the duration of power modules”

“In test cycles we have conducted so far, ranging from -55 °C to 150°C , curamik® silicon nitride substrates have shown more than a 10X improvement over substrates typically used in the Automotive segment, especially HEV/EV. From this data, we can expect to see a longer life span for modules using these substrates,” reports Manfred

 About curamik’s New Ceramic Substrate 

Until now, the reliability of copper-bonded ceramic substrates used in power modules has been limited by the lower flexural strength of the ceramic that can result in reduced thermal cycling resistance. For applications combining extreme thermal and mechanical stress, such as hybrid and electric vehicles (HEV/EV), the current commonly used ceramic substrates are not optimal. The significant difference in thermal expansion coefficients of the substrate (ceramics) and the conductor (copper) exert stress on the bonding zone during thermal cycling, threatening reliability. Rogers Corporation introduced a new silicon nitride ( Si3N4) ceramic substrate under its curamik® ceramic substrates brand. Due to the higher mechanical robustness of silicon nitride relative to other ceramics, the new curamik® substrate is intended to help designers achieve critical, long-life performance under the demanding operating environments and conditions of HEV/EV renewable energy applications and other high reliability applications.

With the growth of HEV/EV and renewable energy applications, designers have struggled to find new ways to ensure reliability of the electronics required to power these new, challenging technologies. With an increase in operating life span of potentially ten times or more relative to other ceramics used in power electronics, silicon nitride substrates provide the mechanical robustness critical to achieving the necessary reliability requirements. The life span of ceramic substrates is measured by the number of repetitions of thermal cycles the substrates can survive without delamination or other failure modes that compromise the function and safety of the circuit. This testing is typically done by cycling the samples from – 55° C to 125°C or 150°C.

In this video interview, we get a chance to hear some insights from our CEO, Bruce Hoechner who officially took office in January this year.  He shares where Rogers is going in the industry and what his thoughts are regarding Rogers future growth in a tough global economy.

Bruce starts by sharing where his focus has been inside the company since he took office:

  • Realignment of the sales organization with Rogers business units to get closer with our customers
  • A focus on marketing excellence around new technologies, new market demands and new applications for Rogers products.  Part of this effort includes working with R&D to put together road maps for future innovation.
  • Understanding the capabilities of Manufacturing Excellence
He then explained how the company’s external efforts are focused around  three megatrends that are shaping the world economy:
  • Internet Growth – From impact protection for handheld devices and tablets to supporting wireless infrastructures with base stations and antenna technologies
  • Clean Technology – To help support sustainability initiatives for Rogers customers with sustainable materials to innovating power-based technologies that support the development of electric vehicles and hybrid vehicles
  • Mass Transit – This includes advanced cushioning and seating solutions for high speed rail systems along with bus bars for rail traction systems

He also discussed Rogers expansion in Asia and what it means to  expand globally but operate locally…

A shout out and thanks to Bruce Hoechner for sharing his thoughts with the Pat Hindle at Microwave Journal…

There has been lots of discussion of how manufacturing is becoming a thing of the past in the United States. Well, we were happy to read in this New York Times article “Does America Need Manufacturing” that there is a shift happening in area of advanced battery technology to help make advancements in clean energy technology.   Not only has the government been providing stimulus money to help drive these efforts, but it’s also promising to help job creation in this tough economy.  Clean energy technology is one of our megatrends that we track, and are actively working on developing new products in this area.

The article notes:

In 2009, the U.S. made less than 2 percent of the world’s lithium-ion batteries. By 2015, the Department of Energy projects that, thanks mostly to the government’s recent largess, the United States will have the capacity to produce 40 percent of them. Whichever country figures out how to lead in the production of lithium-ion batteries will be well positioned to capture “a large piece of the world’s future economic prosperity,” says Arun Majumdar, the head of the Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E). The batteries, he stressed, are essential to the future of the global-transportation business and to a variety of clean-energy industries.

This is good news, we hope the trend continues in this direction.  We are doing our part in advancing this technology.  We recently launched our RO-LINX® PowerCircuit™ Busbars that enable the effective distribution of high voltages and large currents in power electronic modules for HEVs and EVs, while minimizing physical and thermal constraints. On another side, we are working to create more effective lithium ion battery pack assemblies and enclosures using silicone and urethane foams to protect this sensitive technology from harsh environments, improve durability and help extend battery life and capacity which is a huge issue when it comes to all types of EVs.

One thing is for certain, this is a rapidly moving technology that is evolving very quickly. Lithium ion batteries are where it’s at today, but we anticipate there are more advanced battery technologies that are in development now that could become a game changer in clean technology. At Rogers, we’ll continue to be committed to staying on top of clean technology trends and will be developing new products to help respond and meet consumer demands for even better HEV and EV solutions.
