SANTA CLARA CA, -- Cirexx has produced 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 circuits operational in high-heat environments such as aerospace “fire controls,” oil and gas exploration “downhole,” automotive “under-the-hood” and medical autoclave applications.

The firm is commercially offering the products, whichi were developed in concert with DuPont. Trial runs of specifically designed experiments were established to observe, learn and apply the limits and capabilities of the new material. Cirexx engineers correlated the resulting data and added along a number of process techniques, which resulted in the fabrication of the new flex products. 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, Cirexx said.

Cirexx is offering the flex boards in common constructions – single-sided, double-sided, multilayered and rigid-flex.
