HighTemp™ Flex
About
HighTemp™ is a flexible circuit 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 HighTemp™ flexible circuits can perform at temperatures up to 250°C.
All Flex engineers 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.
Some of the markets with increasing requirements around thermal management at extreme temperatures include: down hole oil drilling, semiconductor processing, medical diagnostics and instrumentation, and a multitude of military/aerospace applications.
All Flex is one of the few companies that offers high temperature flexible circuits as well as flexible heaters with Maxi-Flex® lengths of 6′ + .
