The Applications Of Flex Printed Circuits, Flex Printed Circuit Boards

- Aug 17, 2016-

Prior to designing a circuit, there are two fundamental structural applications that must be understood and dictate conductor selection:

Static Application –   An application where flexible circuits are flexed only to install the circuit and fit it into its application (also known as flex-to-fit or flex-to-install). A static application will typically be made using the less expensive Electro Deposited (ED) copper.

Dynamic Flexing Applications A situation where the flexible circuit itself is dynamically (repeatedly) flexed during the actual use of the final product. Common examples include flip-type cell phones, laptops, printer heads and robotic arms. A dynamic application will require the use of Rolled Annealed (RA) copper.

The benefits of flexible circuits are realized in most applications requiring high volume flexing and/or a high degree of accuracy. Some common applications include:

Air bag systems

Automotive engine controls

Antilock brakes


Bar code equipment

Battery packs



Cell phones

Heart monitors and pacemakers

Fuel pumps

Hearing aids


Motion systems

GPS systems
