Abstract
The invention discloses an identifiable flexible printed circuit board (PCB) and a method of fabricating the same. The identifiable flexible PCB includes a flexible substrate, a conductive layer, and a printing ink layer. First, the conductive layer is formed over a surface of the flexible substrate. Second, the printing ink layer is formed on the surface of the flexible substrate by coating, exposing, and developing to uncover parts of the conductive layer. Also, at least one identifiable area is formed on the printing ink layer and one can easily and correctly identify the cartridge with the flexible PCB.
