Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0024] refer to figure 2 , the production process of the circuit board with silica gel button provided by the invention comprises the following steps:

[0025] ①Silicone button injection molding and flexible circuit board gluing: While the silicone button is being injected and molded through the molding mold, the position of the silicone button to be pasted on the flexible circuit board is synchronously positioned and glued on the gluing jig; among them, the molding mold One-to-one correspondence between the injection points and the assembly position of the silicone button on the flexible circuit board to complete the one-to-one correspondence of a single silicone button injection molding;

[0026] ② Lamination and molding of the silicone button and the flexible circuit boar...

Abstract

The invention discloses a production process of a circuit board with silicone keys. The production process comprises the steps of injection molding of the silicone keys, gluing of a flexible circuit board, fitting molding of the silicone keys and the flexible circuit board, discharging inspection and warehousing. Compared with the prior art, the production process of the circuit board with the silicone keys provided by the invention has the advantages that the steps of opening a punching die, forming a bonding assembly line and a bonding jig, baking and the like are omitted; the injection molding step and the fitting molding step can be completed on a same molding die at the same time, so that the product manufacturing time is greatly saved, adverse conditions are reduced, the equipment investment of corresponding steps is saved, and the product production cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of computer keyboard production, in particular to a production process of a circuit board with silica gel keys, and also to a forming mold of the corresponding process. Background technique [0002] The shape of the keyboard key is composed of two parts, namely: the flexible circuit board and a single silicone key that is attached to the flexible circuit board in sequence, and the silicone key is attached to the designated position of the flexible circuit board with a special glue, and then dried After the product assembly is completed, refer to figure 1 , and its specific process flow is: [0003] ①Silicone button injection molding; [0004] ②Use the die to cut the silicone button into a single individual and inspect the individual; [0005] ③Establish a bonding assembly line to bond the silicone button with the flexible circuit board; [0006] ④ Bake the bonded product (baking temperature 120-140°C, ti...
