DuPont Intros Pyralux High Temp Flex Circuit Material System

February 19, 2015 in Industry News

This is very good news for flexible circuit and flexible heater manufacturers. We still need to see the specifications to better understand the lamination process, but this allows flexible circuits to go into high temp areas that were previously unattainable.

DuPont Circuit & Packaging Materials (DuPont) today announced the launch of its DuPont™ Pyralux® high temperature (HT) flexible circuit material system.  Pyralux HT has an service temperature of 225º Celsius, the highest of any flexible circuit material system available today. The Pyralux® HT service temperature enables designers to use flexible circuits for the first time in high-temperature environments such as aerospace and automotive engines, brakes and transmissions, and downhole pumps for oil and gas drilling. DuPont will feature Pyralux® HT, as well as the rest of its innovative portfolio of flexible circuit solutions, at the IPC APEX Conference & Exhibition in San Diego, Calif., from Feb. 24-26, 2015, in booth #1932.

The Pyralux® HT bonding film is part of the HT flexible laminate system that  has the highest service temperature of any flexible circuit material system available today.

“The Pyralux® HT system opens new doors for the use of flexible circuits,” said Mark T. Dirks, global segment leader, DuPont Circuit & Packaging Materials.  “Designers concerned about high temperatures in demanding environments now have an innovative new material that can withstand heat and has the reliability they know they can expect from DuPont materials.”

The all-polyimide Pyralux® HT flexible circuit material system has a service temperature of 225º Celsius (437º Fahrenheit), the highest of any flexible circuit material system.  The system includes a double-sided copper-clad laminate and a unique all-polyimide bonding film that becomes a flexible coverlay after processing.  Offered in a full range of dielectric thicknesses, the Pyralux® HT system provides designers, fabricators and assemblers a versatile option for a wide variety of flexible circuit constructions.

DuPont set the standard for flexible circuit materials more than 20 years ago with the introduction of the Pyralux® AP flexible circuit material system.  The Pyralux® portfolio enables the design of increasingly complex circuits with greater functional capacity, while providing the high reliability, excellent quality and consistency that the industry requires.

DuPont Circuit & Packaging Materials offers a broad and growing portfolio of products including dry film photoresists and phototooling films for Printed Circuit Board (PCB) imaging, polyimide films, flexible circuit materials, embedded passive materials and thermal substrates for LED lighting.
