DuPont has unveiled the DuPont™ Pyralux® ML Series, a double-sided metal-clad laminate, which marks a distinctive addition to its broad range of Pyralux® laminates designed for flexible and rigid-flex printed circuit boards (PCBs). Engineered to deliver superior thermal management, these laminates offer an optimal solution for demanding markets such as aerospace, defense, electric vehicles (EVs), AI-related networking, and various electronic devices. With outstanding performance in challenging conditions, the Pyralux® ML laminate series emerges as a versatile and innovative solution applicable across diverse industries. DuPont is showcasing these groundbreaking laminates during IPC APEX Expo, taking place from April 9-11 at the Anaheim Convention Center.

Laminates serve as the backbone for complex circuits built on both rigid and flexible substrates. They provide mechanical integrity to flex circuits while allowing designers the freedom to fit circuits into the available footprint. The Pyralux® ML double-sided metal-clad laminates have been engineered to address the challenges of thermal management and provide optimized performance and are ideally suited for flexible printed circuits, sensors, heaters, and thermocouples deployed in high-reliability applications that can benefit from unique metals with advanced material performance.

Unlike other Pyralux® products, the Pyralux® ML laminate contains metal alloy, such as copper-nickel (CuNi), featuring Kapton® all-polyimide dielectric technology. The alloys provide essential thermal resistance for heating, thermal conductivity to improve the desired heat transfer, resistivity for higher heat output, and thermoelectric properties as needed for the application. Pyralux® ML laminates are available in a variety of dielectric and foil types, thicknesses, and a range of metal constructions. The laminates are fully compatible with most conventional circuit fabrication processes, making them a versatile product-development option for OEMs, designers and fabricators. Pyralux® ML double-side clads are currently supplied in sheet form and are being strategically rolled out by DuPont Electronics & Industrial.

“At DuPont, we understand the critical role that laminates play in supporting the complex circuits required by our customers. With the launch of Pyralux® ML, we’re proud to add another innovative solution to our extensive family of laminates,” said Thean Ming Tan, global business director, Laminate Products, DuPont Interconnect Solutions. “Our relentless focus on optimizing thermal management and advanced material performance is driven by the evolving needs of industries such as aerospace, defense, and industrial applications with high-performance, high-reliability requirements. As leaders in materials science and engineering, we’re committed to developing new products and applications that push the boundaries of what’s possible, and we’re honored to be a part of such a vital industry.”

“Heightened demand for robust thermal-management capabilities was the impetus for DuPont to leverage our engineering expertise in creating this unique laminate material, which is not available elsewhere,” stated Richard Wessel, applications technology manager, DuPont Interconnect Solutions. “While fabricators have been assembling laminates using base materials with similar properties, the consistent appearance, strong bond strength, and predictable performance of the Pyralux® brand are key benefits for customers that choose Pyralux ML®.”

Pyralux® ML is just one of the innovative solutions that DuPont is exhibiting at IPC APEX Expo. Other key products to be featured:

  • Electroplating chemistries, including copper, nickel, chrome and silver options.
    • One of the newest, Silveron™ GT-210 Durable Silver, is designed for electrical contact applications requiring high conductivity and can tolerate high temperatures with durability exceeding that of hard gold.
  • Full range of Pyralux® laminated circuit materials
    • All-polyimide copper-clad flexible laminates (CCLs), including Pyralux® HT and Pyralux® AP for rigid flex and multilayer flex applications requiring high speed and frequency and reliability
    • Acrylic-based solutions, including Pyralux® FR and Pyralux® LF CCLs, coverlays, bondplys and sheet adhesives
  • Riston® advanced dry film photoresists, the industry standard for high yield, productivity, and ease of use in imaging applications
  • Interra® thin copper-clad laminates, designed for use as embedded-capacitance materials in multilayer rigid PCBs, offer industry-best mechanical strength, reliability and capacitance stability

To learn more about these and other offerings, visit DuPont Interconnect Solutions at IPC APEX Expo. The company will exhibit and present Power Chats in the Insulectro Technology Village, Booth 3306, and will share Booth 4848 with Tritek Circuit Products.
