Bendable area design for flexible printed circuitboard
First Claim
1. A flexible printed circuit board with bendable area, comprising:
- a flexible substrate, further comprising;
at least a circuit pattern, each formed on the flexible substrate; and
a bendable area, configured in the flexible substrate while intersecting the at least one circuit pattern; and
at least a groove, formed in the bendable area at a position corresponding to the intersection with the at least one circuit pattern;
wherein the flexible substrate has two circuit patterns formed thereon, and one of the two circuit patterns is configured with a region that is wide enough to cover the whole bendable area therein and thus is provided for the formation of the at least one groove while the two ends of the wide region away from the bendable area are tapered into a width the same as that of another circuit pattern.

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.
