High-Temperature Flexible Circuit Material System

DuPont Circuit & Packaging Materials(DuPont) today announced the launch of its DuPont™ Pyralux® high-temperature (HT) flexible circuit material system. Pyralux® HT has a service temperature of 225 degrees 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.

“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 225 degrees Celsius (437 degrees 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.
