Embodiment 1

[0046] This embodiment is used to illustrate the keyboard assembly provided by the present invention and its manufacturing method.

[0047] Print light-guiding ink (Baolai, PF-80923B) on one surface of a PC sheet with a size of 276x175x0.1mm using the method of screen printing to form such as figure 1 As shown in the pattern, then use the method of screen printing to print black ink (Imperial ink of Japan, 1NQ-971) all on the same surface of the PC sheet, and then carry out far-infrared baking to the formed ink layer, The baking temperature is 100° C., and the baking time is 10 minutes.

[0048] Coat the two surfaces of the above-mentioned PC sheet with an activation treatment agent (Shenzhen Cicai Chemical Technology Co., Ltd., 500A and 500B), let it stand and bake at 60°C for 60 minutes, and the activation treatment agent is dried to form a thickness of 0.01 mm bonding layer. Liquid silica gel (Zhongshan Polymeric Electronic Materials Co., Ltd., 9150A and 9150B) is coated ...

Abstract

A keypad assembly comprises a plastic substrate; a first silicone rubber layer; and a first adhesive layer disposed between a back surface of the plastic substrate and a front surface of the first silicone rubber layer, the first silicone rubber layer has a plurality of first protrusions on a back surface thereof.

Description

technical field [0001] The invention relates to a keyboard component, a manufacturing method thereof and a keyboard. Background technique [0002] With the rapid development of science and technology today, people have higher and higher requirements for mobile phones. Not only must mobile phones have complete functions and excellent quality, but also put forward higher requirements for the appearance and thickness of mobile phones. [0003] For ultra-thin key components, due to the limitations of the manufacturing process, its thickness problem has been difficult to solve. At the same time, a separate structure is adopted in the key font lighting. There are two main manufacturing methods for the existing ultra-thin keys: plastic flat keyboard method and Ultra-thin P+R method, and then assemble the case on the shrapnel covering the light guide film to form a component. [0004] The plastic tablet keyboard assembly is composed of a plastic tablet and a silica gel, and its pro...
