Design Freedom
Flex circuits bend, fold, twist, and roll to fit any geometry — enabling 3D packaging impossible with rigid boards. No longer restricted by bulky, rigid PC board space demands.
Space Savings — Up to 75%
Flex circuits conform to available space, achieving up to 75% space savings versus rigid board assemblies. Typical rigid board is 62 mils thick — flex is 4–11 mils.
Weight Reduction — Up to 70%
Raw materials in flex offer weight savings as high as 70% versus rigid boards. For aerospace, wearables, and portable devices where weight matters, this advantage is decisive.
500M+ Flex Cycles
KAPTON polyimide survives vibration and shock that destroys rigid boards. In dynamic applications, properly designed flex circuits withstand up to 500 million flex cycles without failure.
Thermal Performance
Larger surface-to-volume ratio enables increased heat dissipation. KAPTON’s exceptional thermal stability allows operation in extreme temperature environments.
Production Cost Savings
Less manual assembly labor. Elimination of routing, wrapping, and soldering costs. Complete interconnection systems installed as one unit. Automation reduces human error.
