Problems solved by technology

For products with arbitrary curved surfaces, the problem of curved surfaces can be overcome by adjusting the distance of focus (DOF) of the laser or using 3D cutting technology, but the quality control of the cutting is not easy, and the heat generated during the cutting process may also damage the adhesive material
Therefore, the cost of 3D laser cutting equipment is high, time-consuming, and the economic effect is low

Abstract

The invention discloses a manufacturing method for a curved surface touch module. An existing curved surface touch product needs to be trimmed again after a thermoplastic lamination process, so that product quality control management is difficult; a protective layer is used for avoiding damage of a conductive film in a thermoplastic process, and meanwhile, the protective layer is taken as a bearing film; a touch sensing layer is semi-cut, so that after the thermoplastic lamination process, the protective layer only needs to be removed, and the trimming action does not need to be performed again; and therefore, the process yield can be effectively increased, and the production cost is reduced.

Description

technical field [0001] The present invention relates to a method for manufacturing a touch module, in particular to a method for manufacturing a curved touch module that does not need trimming. Background technique [0002] With the evolution of the times, technology products are getting closer and closer to life. The physical buttons on most products have been gradually replaced by touch technology. The touch interface has also developed from a simple flat shape to a curved surface shape along with the appearance of the product. In response to the development of curved surface touch products, a thermoplastic process is introduced to achieve the required product curvature. Plastic materials are mainly used as the substrate of the conductive film. Edge (trimming) to improve the appearance quality of the product. [0003] At present, laser cutting is the most widely used for product trimming. For products with arbitrary curved surfaces, the problem of curved surfaces can be ...
