Embodiment Construction

[0038] In order to enable those skilled in the art to understand the purpose of the present invention, preferred embodiments of the present invention are described in detail as follows.

[0039] Please refer to Figure 4 , in one embodiment, the long carbon chain silane compound is deposited on the edge of the connection between a panel 3 and a frame 4 by vacuum chemical vapor deposition. The panel is a glass panel. The panel 3 and the frame body 4 are pressed together first, and the panel 3 and the frame body 4 are bonded with glue 5 to form an assembly. Then part of the panel 3 is covered with a mask 6 to expose the surface to be deposited. Then use ozone plasma 12 to modify the surface to be deposited.

[0040] Put the assembly into a vacuum reaction chamber 11, ensure that there is no other gas in the reaction chamber to interfere with the subsequent reaction, and heat the vacuum reaction chamber to 40° C., and introduce a gas 7 containing a precursor solution of long c...

Abstract

The invention provides an airtight waterproof method adopting a chemical vapor deposition long carbon chain silicone compound between a panel and a frame body. The airtight waterproof method includesthe step of depositing the long carbon chain silicone compound at the contact edge of the frame body and the panel, wherein a precursor solution of the long carbon chain silicone compound comprises 1v / v% of the long carbon chain silicone compound and 99 v / v% of isopropanol. The long carbon chain silicone compound is tetraethyl orthosilicate (TEOS).

Description

technical field [0001] The field of the present invention relates to the field of panel assembly, in particular to the field of panel waterproof assembly technology. Background technique [0002] Before many components leave the factory, an air leak test (Air Leak Test, ALT) must be performed between the surface glass (Cover Glass, CG) and the frame (Frame), the purpose of which is to test the waterproofness of the component. The airtightness detection method is to place the glass and the frame in a cavity, and make the bonding surface of the glass and the frame form a closed space, and then fill the space with air to detect whether there is air leakage (such as figure 1 ). figure 1 The leak tester 1 will discharge the gas charged by the test gas source 2; the positive pressure of the gas can be, for example, 1.25 atmospheric pressure. If the colloid between the glass surface and the loading frame is defective, the leakage air pressure will be detected by the self-connecti...
