Cirexx Develops High-Heat Flex Circuits with HT Material

Estimated reading time: 2 minutes

Cirexx International now commercially offers a line of flexible circuit products that employ the recently developed DuPont Pyralux high-temperature HT material. The HT material is designed to operate at temperatures of up to 225°C, making the flex circuit ideal for high-heat environments such as aerospace fire controls, downhole oil and gas exploration, and automotive under-hood and medical autoclave applications. 

Cirexx engineers worked closely with DuPont engineers in the development of the HT materials.  Several trial runs of specifically designed experiments were established to observe, learn and apply the limits and capabilities of this new material.  Cirexx engineers correlated the resulting data and added along a number of process techniques all of which resulted in the fabrication of a line of high-heat flexible circuits.  The material requires some specific special processing – lamination presses capable of reaching and holding temperatures of 600°C – and must be uniquely engineered for stability for each application. 

The Cirexx High-Heat Flexible Circuits are available in all of the common constructions – single-sided, double-sided, multi-layered and rigid-flex and represent the highest temperature rating of any flex circuit material system available.  It allows the user to enjoy the traditional benefits of a flex circuit – light weight, smaller, point-to-point customer wiring and miniaturization – while surviving a high heat environment.
