2-Layer Flexible Printed Circuit Board

A 2-layer flexible printed circuit board built on polyimide laminate, designed for general-purpose interconnect in compact and bend-required electronic assemblies. The double-layer construction provides routing density on both sides of the polyimide film, supporting power, ground, and signal traces in a single bend-tolerant substrate that can replace rigid boards plus discrete cable harnesses. Typical applications include consumer device internal wiring, automotive lighting and dashboard interconnects, industrial sensor leads, and IoT module bridges. Manufacturing uses rolled-annealed copper imaging, polyimide coverlay lamination, plated-through-hole or microvia formation between the two layers, and laser cutting to drop-in form factors. The result is a thin, lightweight interconnect that survives repeated mechanical flexing while maintaining electrical continuity over long product lifetimes.
