Abstract

The invention provides a method for covering an FPC with a film and a device for realizing the method. The method comprises steps of adopting a film positioning step to position an FPC and a protective film, performing click prepressing and dot matrix pre-hot pressing to achieve dot matrix pre-fixing and minimize the gap between the protective film and the FPC, and finally performing the entire surface hot pressing. The dot matrix fixed point has a guiding role, and the hot-melt glue can be quickly and evenly applied after the entire surface hot pressing and is not easy to generate bubbles, sothat the protective film covers uniformly and the yield rate is high. A full-automatic film applicator for realizing the above method not only achieves the above high-yield operation, but also realizes full-automatic production, so that the production efficiency is remarkably improved, and at the same time the continuity of the Roll TO Roll process is satisfied, and the FPC is not required to becut before film covering operation.

Description

technical field [0001] The invention relates to the field of FPC technology, in particular to an FPC covering film method and device. Background technique [0002] FPC (Flexible Printed Circuit, flexible circuit board), also known as soft board, is a highly reliable and flexible printed circuit board made of polyimide or polyester film as the base material. , an indispensable and important connector for automotive consumption and electronic products. In order to ensure that the FPC can still be used normally in the harsh environment of high temperature, humidity, pollutants and corrosive gases, it is necessary to attach a cover film to the surface of the FPC to meet the requirements. [0003] Most of the existing FPC Roll to Roll (roll to roll) process is done after the graphic circuit is completed, which is used as a watershed between Roll to Roll (roll to roll) and PNL to PNL (chip to chip) process. Cut into sheets below 250*350mm, then film, laminate, and finally do oth...
