DuPont Pyralux AP to Aid Reliable Performance of Semikron-Danfoss eMPack Modules Powering Next-Gen EV
September 22, 2022 | DuPontEstimated reading time: 1 minute

DuPont Interconnect Solutions, part of the Electronics & Industrial business, announced a multiyear contract with European power module manufacturer Semikron-Danfoss who will integrate DuPont™ Pyralux® AP all-polyimide double-sided copper clad laminate into its eMPack® power modules to further enhance the capabilities of next-gen electric vehicles.
Integrating Pyralux® AP copper clad laminate into eMPack® traction inverter designs will help EV automotive engineers address key requirements related to signal integrity and power transmission. The characteristics of Pyralux® AP benefiting this application from Semikron-Danfoss include:
- Robust thermal resistance for temperature stability
- All-polyimide dielectric layer
- Extreme durability
- Excellent bond strength for automotive-grade reliability
- Excellent low dissipation loss characteristics
- Superior electrical performance
- Consistent signal integrity
Further, Pyralux® AP’s dielectric thickness tolerance and low coefficient of thermal expansion make it ideal for rigid flex or multiple layer flex applications. The adhesive-less flexible circuit material has a flammability rating of UL 94-V0, a maximum operating temperature of 200°C, and is certified to IPC 4204A/11.
"Pyralux® AP emerged as our best-fit solution after extensive testing and because the product has demonstrated three decades of stable, reliable performance in a variety of industries where operating conditions, like ours, are severe,” said Karl-Heinz Gaubatz, CTO of Semikron. “eMPack® is a perfect fit to SiC MOSFET power modules. We look forward to working with DuPont and their Pyralux® technology to help eMPack® become a global leader in EV power modules.”
Earlier this year, Semikron-Danfoss, headquartered in Nuremburg, Germany, won a billion-Euro contract beginning in 2025 to furnish patented eMPack® power modules to a major German automotive manufacturer. Within silicon-carbide MOSFET or full silicon-carbide technology-based modules, traction inverters can be created which are extremely compact, scalable, and reliable because of a Semikron double side sintered assembly and connection technology called Direct Pressed Die (DPD).
“We are excited how this EV power module application of Pyralux® AP copper clad laminate supports a sustainable and electrified future to help preserve our planet for generations to come,” said Andy Kannurpatti, Global Business Director, Films & Laminates, DuPont Interconnect Solutions. “The eMPack® power module is expected to enable millions of next-gen electric vehicles by 2032. We look forward to contributing significantly to the much-anticipated success of eMPack® and appreciate the collaboration with Semikron-Danfoss.”

Connect the Dots: Sequential Lamination in HDI PCB Manufacturing
07/31/2025 | Matt Stevenson -- Column: Connect the DotsAs HDI technology becomes mainstream in high-speed and miniaturized electronics, understanding the PCB manufacturing process can help PCB design engineers create successful, cost-effective designs using advanced technologies. Designs that incorporate blind and buried vias, boards with space constraints, sensitive signal integrity requirements, or internal heat dissipation concerns are often candidates for HDI technology and usually require sequential lamination to satisfy the requirements.

07/22/2025 | Vern Solberg -- Column: Designer's NotebookPrinted circuit board development flows more smoothly when all critical issues are predefined and understood from the start. As a basic planning strategy, the designer must first consider the product performance criteria, then determine the specific industry standards or specifications that the product must meet. Planning also includes a review of all significant issues that may affect the product’s manufacture, performance, reliability, overall quality, and safety.
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
07/18/2025 | Nolan Johnson, I-Connect007It may be the middle of the summer, but the news doesn’t quit, and there’s plenty to talk about this week, whether you’re talking technical or on a global scale. When I have to choose six items instead of my regular five, you know it’s good. I start by highlighting my interview with Martyn Gaudion on his latest book, share some concerning tariff news, follow that up with some promising (and not-so-promising) investments, and feature a paper from last January’s inaugural Pan-European Design Conference.
