Abstract

The invention discloses an FPC module with balanced deflection stress and an electronic device, and relates to the technical field of electronic circuits. The FPC module comprises a first terminal on which a first circuit is distributed, a second terminal on which a second circuit is distributed, and at least three bridging units connected with the first wiring terminal and the second wiring terminal and arranged side by side; a third circuit is distributed on the bridging units, and the first circuit and the second circuit are connected through the third circuit; and the at least three bridging units are used for forming a polygonal three-dimensional supporting structure through reverse bending and staggering. The FPC is designed to be provided with a plurality of bridging units which can form the three-dimensional supporting structure in a staggered mode, the center of the supporting point is located in the center of the three-dimensional supporting structure, balance of deflection stress of the FPC in all directions is facilitated, the stress of the FPC is weakened to a certain degree, the development difficulty of deflection control can be reduced, the linear relation between the deflection degree and the control parameters is improved, and the reliability and stability of FPC deflection control are ensured.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, in particular to an FPC module and an electronic device for balancing deflection stress. Background technique [0002] FPC (Flexible Printed Circuit board, flexible printed circuit board), also known as flexible circuit board, which is made of a series of film materials such as polyimide or polyester film, has high reliability and is absolutely The best flexible printed circuit board, referred to as soft board or FPC, has the characteristics of high wiring density, light weight, and thin thickness. It is widely used in many fields such as automotive electronics, consumer electronics, home appliances, and industrial equipment. [0003] In order to meet the development needs of miniaturization and miniaturization of electronic devices, the demand for FPC flexible circuit boards is no longer limited to bending resistance, but needs to be coordinated to meet more precise control. For exa...
