Problems solved by technology

However, when flexible circuit boards are applied to various electronic products, the wiring conditions required for each part of the flexible circuit board and the degree of bending and winding required are usually different. In multilayer flexible circuit boards, the entire flexible circuit When the stacked structure of the board is consistent, it is easy to cause the flexibility of the part that needs to be bent and wound to decrease due to the number of layers and excessive thickness, which will lead to a short life of the flexible circuit board; at the same time, the entire When the stacked structure of the flexible circuit board is consistent, it is also easy to cause the part of the flexible circuit board that needs more wiring to be routed to other places due to insufficient layers, which will affect the electrical properties of the wiring.

Abstract

The invention discloses a flexible circuit board which comprises a flexible circuit board body and a first additional flexible circuit board. The flexible circuit board body comprises a mounting area and a bending area which are connected with each other. The first additional flexible circuit board is laminated on the mounting area. The surface area of the first additional circuit board is smaller than or equal to that of the mounting area. The thicknesses of portions which require bending and winding on the flexible circuit board are small, and furthermore the flexible circuit board has high flexibility. Furthermore, the number of layers at a portion which requires multiple wirings on the flexible circuit board is large, thereby enlarging wiring area. The invention furthermore discloses a terminal.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a flexible circuit board and a terminal. Background technique [0002] Flexible printed circuit (FPC, FlexiblePrintedCircuit) is a printed circuit board made of flexible materials. It has the advantages of high wiring density, light weight, thin thickness and soft material. It can be bent, wound and folded, so , Widely used in the conductive system of various modern electronic products. According to the number of wiring layers contained in the flexible circuit board, the flexible circuit board is usually divided into a single-layer flexible board, a double-layer flexible board and a multi-layer flexible board. In the prior art, regardless of the number of wiring layers contained in the flexible circuit board How much, the laminated structure of the entire flexible circuit board is consistent. However, when flexible circuit boards are applied to various electronic products, the wir...
