What is FPC and How does it work ?
Flexible printed circuits, also known as (flex circuits), are sometimes regarded as a (printed circuit board) (PCB) that can bend, when in reality there are significant differences between PCB's and flex circuits when it comes to design, fabrication and functionality
Since flex circuits (flexible circuit) has excellent working efficiency and strong heat-resistance, it is widely used as a core component of all electronic goods such as cameras, computers and peripheral equipments, mobile phones, video & audio units, camcorders, printers, DVD, TFT LCD, satellite equipment, military equipments, and medical instruments.
