Cirexx Develops High Heat Flex Circuits With HT Material

Cirexx now 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”, oil & gas exploration “downhole”, 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 data added and along with a few process techniques resulted in the fabrication of a line of High Heat Flexible Circuits. The material requires some special processing (lamination presses capable of reaching and holding temperatures of 600°C) and must be engineered for stability uniquely 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 operating in a high heat environment.
