Embodiment Construction

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0032] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention, which belongs to the technical field of the flexible circuit board manufacturing, provides a flexible circuit board reinforcing method and a flexible circuit board. The method comprises: four mark points are arranged at a welding plate of a flexible circuit board and a plane where a component is located and an annular copper-free area is formed around each mark point; the four mark points and the annular copper-free area are printed with white ink; and the four mark points are identified and selected for positioning by using an automatic reinforcing machine to carry out pasting reinforcement. According to the method provided by the invention, the mark points and the welding plate are located at the same plane, so that positioning becomes accurate; and during the dual-side manufacturing process of the flexible circuit board, a phenomenon that the tolerance of the welding plate and the reinforced edge is reduced by staggering of two copper layers can be avoided, so that the pasting reinforcement precision is improved.

Description

technical field [0001] The invention belongs to the technical field of flexible circuit board production, and more specifically relates to a method for reinforcing a flexible circuit board and a flexible circuit board bonded and reinforced by the method. Background technique [0002] FPC (Flexible Printed Circuit Board) is a flexible circuit board. Due to the softness of FPC, if welding components on one side of FPC, it is necessary to paste auxiliary materials such as steel sheet, aluminum sheet, and glass cloth substrate FR-4 on the opposite side of the FPC component, which is called For reinforcement (or strength protection), it is used to increase the hardness and thickness of the FPC at this position, improve the flatness of the FPC, and ensure good welding of components and FPC. [0003] When reinforcing, the way to use the automatic paste reinforcement machine to fit and reinforce is to place the FPC board on the table, select four positioning points at the four corn...
