A kind of fpc reinforcing board production process and its products

Abstract

The invention discloses an FPC reinforcement plate production technology and a product. The technology mainly comprises the following steps of pasting a reinforcement plate on an FPC plate; pasting aprotection film on the reinforcement plate; prepressing the protection film under a low temperature and low pressure so that the protection film wraps the FPC reinforcement plate and the protection film is not contacted with a surface of the FPC plate; punching the FPC plate into a single piece; and pressing and solidifying the protection film under a high temperature and high pressure so that theprotection film is tightly contacted with the FPC plate. By using the production technology, an exposure problem of the reinforcement plate is solved. In the product manufactured through the production technology of the invention, the protection film tightly wraps the reinforcement plate so that the reinforcement plate is not exposed and insulation and beauty effects are reached; and an edge of the reinforcement plate does not generate bubbles and a product yield rate is high.

Description

technical field [0001] The invention relates to the field of FPC battery boards, in particular to a production process and a product thereof for sticking a protective film on the thick reinforced surface of the FPC. Background technique [0002] With the extensive use of electronic products, the integration of FPC boards as flexible circuits has been widely used in various electronic products. Due to the light, thin, short and small characteristics of the FPC board, there will be a process of attaching the reinforcement board during the production process, and various reinforcement boards (such as: steel sheet, FR4, PI, etc.) are pasted on the FPC board , used to enhance the supporting capacity of the FPC board. [0003] Among them, in the production of battery panels, steel sheets are usually selected as their reinforcing plates. When the steel sheet is used as the reinforcement board, in order to prevent the steel sheet from colliding with other lines and cause short cir...

AI Technical Summary

Problems solved by technology

However, in the lamination process of the protective film, the phenomenon of pressure failure often occurs. Due to the large area of ​​the protective film and poor tensile ability, it is bonded to the FPC prematurely during the lamination process, so that the protective film cannot be reinforced after being stressed. The edge of the board shrinks, forming air bubbles at the edge of the reinforcement board, so that the protective film cannot wrap the reinforcement board tightly, resulting in poor reinforcement of the exposed reinforcement board after punching a single piece, with a defect rate of 80%, which seriously affects production. It not only wastes production capacity, but also increases production costs such as labor and materials.
