Flexible printed circuit boards: Innovation through maximum flexibility

Flexible printed circuit boards (flex PCBs) consist of very thin polyimide films with extremely fine copper structures embedded in them. This allows circuits to be bent in three-dimensional space and used in dynamic applications—a clear advantage over rigid printed circuit boards. In modern, technically sophisticated assemblies, miniaturization, weight reduction, lower assembly costs, and cost pressure are becoming increasingly important.

Wiring harnesses and connectors can therefore be reduced or even replaced by flexible printed circuit boards. Typical areas of application include wearables, smartphones, sensor technology, foldable displays, keyboard foils, lighting systems—and anywhere else where complex electronic circuits need to be accommodated in a very small space.

The advantages of flexible printed circuit boards

Complex circuits with maximum space savings and mobility.

Space and weight savings

Reduction of installation space by up to 75% through three-dimensional folding and integration. Weight savings through elimination of cables and connectors.


Integrated vibration-resistant circuit carrier 

Highly resilient connections without separate connectors and cables. Perfect for dynamic applications with high mechanical stress.

Efficient thermal management

The minimal use of material and flat copper layers enable optimal thermal management in compact installation spaces.

Variants of flexible printed circuit boards

Depending on requirements, we offer various designs of flexible printed circuit boards – from simple single-layer circuits to complex rigid-flex combinations.

Multilayer flexible printed circuit boards

Three or more copper layers, more complex circuits, impedance-controlled, 3D routing in wearables and foldable displays.

Rigid-flex printed circuit boards

Combination of rigid and flexible PCB parts. Ideal for space- and weight-optimized assemblies without separate cable routing.

Single-layer flex PCBs

A copper layer, simple structure, very thin, light, and flexible. Ideal for simple connections and sensor technology.

Two-layer flex PCBs

Two copper layers, increased packing density with plated vias. Enables more complex circuits.

Semi-flex printed circuit boards

Rigid FR4 with defined partial Z-axis milling in the bending area. Bending radius max. 20° with bending aid.

Rigid-flex printed circuit boards

Combination of rigid and flexible PCB parts. Ideal for space- and weight-optimized assemblies without separate cable routing.
