All Flex is now offering flexible circuits with material constructions that significantly exceed the top temp performance typically offered by flex circuit suppliers. While traditional polyimide constructions are rated to perform well at temperatures up to 150ºC – 200ºC, the High Temp Flexible Circuits can perform at temperatures up to 250°C.
About HighTemp™ Flexible Circuits
All Flex is now offering flexible circuits with material constructions that significantly exceed the top temp performance typically offered by flex circuit suppliers. While traditional polyimide constructions are rated to perform well at temperatures up to 150ºC – 200ºC, the High Temp Flexible Circuits can perform at temperatures up to 250°C.
All Flex developed this product for applications challenged by requirements for temperature extremes as our customers demand superior thermal performance.
All Flex engineering developed this capability by testing a range of materials under a variety of processing options. Premium performance in challenging environments was achieved with a combination of newly developed materials and unique fabrication processes.
Increasing demands for markets requiring thermal management at extreme temperatures include: down hole oil drilling, semiconductor processing, medical diagnostics and instrumentation, and a multitude of military/aerospace requirements.
All Flex is one of the few companies that offer high temperature flexible circuits as well as flexible heaters with Maxi-flex® lengths of 6′ + .
