The invention provides a dual-layer flexible printed circuit board. The dual-layer flexible printed circuit board comprises a printed circuit board slot and a connecting finger, wherein the printed circuit board slot is arranged at a head of each structure and is symmetrically arranged at the other end, and is used for fixing each layer structure of the printed circuit board, the connecting fingeris arranged above the printed circuit board slot, one end of the connecting finger is embedded in the printed circuit board slot, the other end thereof is exposed, and the connecting finger is used for interacting information with a read device. When the printed circuit board is bent, a convex part can be shrunk, so as to reduce stress generated by tension of an outer plate in bending of the printed circuit board, therefore, the printed circuit board is not damaged due to change of self-stress, and has a longer service life. The printed circuit board can exchange and transfer signals with various devices through the printed circuit board slot and the connecting finger, and can be fixed in various structures through rivet holes, thereby being used widely. The dual-layer flexible printed circuit board can be used in production of the flexible printed circuit board, and has a good development prospect.
Description
technical field [0001] The invention relates to the field of flexible printed circuit boards, in particular to a flexible circuit board. Background technique [0002] Flexible printed circuit board, also known as flexible circuit board, is a special printed circuit board. It is characterized by light weight, thin thickness, softness and bendability. It is mainly used in many products such as mobile phones, notebook computers, PDAs, digital cameras, and liquid crystal displays. [0003] The existing flexible circuit board needs to be bent so that it can adapt to the shape of the installation site so that the circuit board can stably connect the equipment at both ends. And the cracking and breaking of the structure occurs, making the circuit board damaged and unusable. Contents of the invention [0004] The main purpose of the present invention is to provide a double-layer flexible circuit board, which can use the convex structure to bend at a larger angle, and simultaneo...
