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
Bar code equipment
Heart monitors and pacemakers
