Etched Foil Flex Cables

If you need reliable power distribution in critical applications, Fralock extended length flexible circuits can provide your solution. We have the unique ability to manufacture extended length flexible circuits without the need for splicing. With ultra-thin, lightweight polyimide, etched-foil construction and extreme flexibility, our flex cables are an excellent fit for harsh environments and applications where space and weight requirements are critical. While maintaining flexibility at temperature extremes from -269°C to +220°C, these cables are manufactured with precision technology and can reach up to 50 ft length.

Adhesiveless Lamination Technology (ALT)

Fralock’s Adhesiveless Lamination Technology (ALT) technology enables hard creasing of our flexible circuits and harnesses without the risk of delamination or trace swim. They also provide a 30% mass savings over traditional flex harnesses, which use temperature-limiting adhesives, and their electronic components are encapsulated for protection from environmental disturbances. Flex circuits made with ALT are included in our ALT Dura™ product group.

Extended length substrates include polyimide, polyester, PEN, and Cirlex®. Foils include copper, Copper/Nickel, Nichrome, Stainless, Monel, and Inconel. Our extended length flex circuits can be fabricated with or without adhesive.

If you require high durability, wide operational temperature range, superior heat dissipation, low outgassing, and resistance to chemical and physical stresses, our flex cables are the optimal solution.
