Flexible circuits (also variously referred to around the globe as flex circuits, flexible printed circuit boards, flex print, Flexi-circuits) are members of electronic and interconnection family. They consist of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits
As the demand for even more compact electronics grows, so does the need for ultra-thin flex PCBs. PCBs are essential to the development of compact electronics for mobile, implantable and other small devices.
