LONG FLEX CIRCUITS

Built for Aerospace & Defense
long flex circuits

Tech Etch long flex circuits support lengths up to 60 inches for space-constrained aerospace and defense systems requiring ultra-thin, lightweight interconnects.

Validated through Laser Direct Imaging, precision etch, and plating, these constructions enable fine line/space geometries, ultra-thin core materials, and 9 μm metal layers with accurate layer-to-layer alignment. Designed for avionics, satellite, radar, and secure communications applications, they deliver reliable electrical performance and mechanical durability in vibration, shock, and dynamic flex environments.
