Flexible PCBs

POE focuses on the fabrication of bare flexible printed circuit boards (FPCs) for rapid prototyping and volume production. We process PI and PET-based flex cores with RA or ED copper, delivering stable roll-to-roll consistency and tight dimensional control for dynamic bend applications.
Our dedicated flex lines support precision etching, micro drilling/laser vias, coverlay application, and surface finish for bare FPCs ready for downstream assembly. From thin single-layer jumpers to multilayer flex with impedance control, we build to your design intent and reliability targets.

APPLICATION OF
FLEXIBEL PCB

Bare flexible PCBs enable ultra-thin, lightweight, and highly bendable interconnects for compact devices. Provide your Gerber and stack-up intent, and POE fabricates stable bare flex circuits with consistent copper uniformity and excellent bend fatigue performance. Ideal for dynamic flexing, tight enclosures, and weight-sensitive designs.
