Patent ID: 7948763

Claim:
A module with flexible printed circuit board (FPC), comprising: a first device; a second device on said first device; a first FPC extending along a plane and connected to said first device, wherein the first FPC includes an elastic portion comprising a bend structure within the plane and at a location between distal ends of the first FPC when no force is applied; and a second FPC connected to said second device, wherein the first and second FPCs are connected at an connection end, and wherein the connection end, a part of the first FPC, and a part of the second FPC are positioned under a reverse side of the first device, with the first FPC bent into a curved structure by extending and flexing the bend structure by a pulling force applied in an extending direction, wherein the first FPC has a first overall length when no force is applied, and wherein when a the pulling force is applied to the first FPC along the extending direction, the bend structure of the elastic portion is flexed to extend along the extending direction such that the first FPC has a second overall length longer than the first overall length.
