Dupont HT

Cirexx International has roughly two “woodshed” years invested in the development of HT materials for use in Flex Circuits.  With many designs and constructions produced and 2 additional – for a total of 3 – High Temperature Lamination Presses.

The company has become a DuPont designated  leader in HT Flex Circuits.

Cirexx is able to offer a complete 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 and served as a DuPont Beta site during development.  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 equipment capable of reaching and holding temperatures of 600°C – and must be uniquely engineered to maintain stability in each application.

The Cirexx High Heat Flexible Circuits are available in a number 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.

If you have a heat issue with your Flex Circuits, Cirexx has the COOL SOLUTION!
