Produced on copper coated polyimide our custom flexible circuits are used in a range of appliances where a circuit that can be moved frequently is required, such as on a hinged lid. As the copper is bonded to the polyimide it can withstand flexing and movement without any adverse effects. Components such as LEDs and switches can be soldered to the circuits and locally applied stiffeners allow bulkier components such as IDC connectors to be applied.

Being produced on a flexible material the circuits can be cut to any shape or size, meaning a circuit can incorporate multiple flexible tails removing the need for extra ribbon cables between PCBs. With the copper being chemically etched to form the trackwork, intricate and complex multi-layer circuits can be created that can be finished in a variety of processes such as gold plating.

Advantages of flexible circuit design

Reduce messy, time consuming wire harnesses. Space and weight reduction coupled to robust connections and fast assembly,


Excellent performance in high vibration applications- flexibility reduces stress on solder joints.

Polyimide covering protects circuits in harsh environments


Excellent performance in high speed signal transmission applications. Uniform spacings between conductors and ground helps to control impedance and reduce crosstalk.

A common question when it comes to flex design is “what is the minimum bend radius that I can work with?”
A good rule of thumb to go by is a minimum of 6x the circuit thickness with single layer flex circuit the best choice for flexible areas. Typically, a layer is 0.15mm thick

Single-layer: 6 × circuit thickness (minimum)
Double-layer: 12 × circuit thickness (minimum)
Multilayer: 24 × circuit thickness (minimum)
