Here at GC Aero, we specialize in manufacturing and assembling flexible circuits, but what exactly is a flexible circuit? Think of a flex circuit as a conductor that is able to bend and flex so that it can fit into a range of electronics.
It is often made using a thin polymer film that acts as an insulator with circuits attached that conduct electricity. The circuits can be made out of a variety of different materials, though copper is the most popular. Gold or solder might be used as a protective layer over the copper so that it doesn’t oxidize.
What really sets a flex circuit board apart is its ability to bend and flex, which can save an incredible amount of space and weight within an electronic device. In part, this factor is what has led to the proliferation of small-yet-powerful electronic devices.
There are several different types of flex circuits, including:
