ABSTRACT:
A bendable area design for flexible printed circuitboard is disclosed. The flexible printed circuitboard (FPC) is comprised of: a flexible substrate; at least a circuit pattern; and a bendable area, being formed intersecting with the at least one circuit pattern and having at least a groove formed therein at a position corresponding to the intersection with the at least one circuit pattern; wherein the depth of the at least one groove is no larger than the thickness of the corresponding circuit pattern for preventing the circuit pattern from being cut off by the groove. By configuring the aforesaid bendable area in the FPC, stress generated by the bending of the FPC is restricted inside the bendable area effectively so that accurate control of the bending angle for bending FPC can be realized.
