Embodiment Construction

[0021] A kind of connection method of mobile phone sapphire screen and metal enclosure is carried out according to the following steps among the present invention:

[0022] Step a, the surface of the sapphire screen and the titanium alloy frame to be electroless plated are respectively polished with 180# sandpaper, and then ultrasonically cleaned with acetone at room temperature for 10 minutes;

[0023] Step b. Cover the remaining part of the exposed sapphire screen to be connected after the treatment in step 1, and use electroless plating to first plate a layer of metal nickel, and then plate a layer of SnAgCu;

[0024] Step c, expose the titanium alloy metal frame to cover the remaining part of the connecting surface, first plate a layer of metal nickel by electroless plating, and then plate a layer of SnAgCu;

[0025] Step d, place the sapphire screen to be connected and the titanium alloy frame to be connected, and fix it with the fixture (see figure 1 ), and then use a 1...

Abstract

The invention relates to a method for connecting a mobile phone sapphire screen with a metal bounding frame and belongs to the technical field of welding. The technical problem that deformation is prone to being produced due to the fact that a large amount of heat is produced through an existing welding mode is solved. SnAgCu serves as brazing filler metal of the method. The method comprises the steps that the sapphire screen is metalized at first, that is, the sapphire screen is plated with a layer of nickel at first and then plated with a layer of SnAgCu; the titanium alloy bounding frame also needs to be selectively plated with a layer of nickel at first and then plated with a layer of SnAgCu; and the SnAgCu brazing filler metal is melted with a small-power laser finally, connecting of the sapphire screen and the titanium alloy bounding frame is completed, a reliable connecting joint is obtained, and the connecting joint is compact in structure and free of pores and has the good air tightness. The method is especially suitable for connecting of the sapphire screen and the metal bounding frame. The shear strength of the connecting joint can reach 105 Mpa.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a connection method between a sapphire screen for a mobile phone and a metal enclosure. Background technique [0002] Sapphire is an expensive natural gemstone, and the sapphire screen is made by purifying ordinary gemstones, basically does not show blue color, but has extremely high hardness. Sapphire screen technology has actually been around for a while. For example, TAG Heuer watches and the glass of military vehicles all use sapphire technology. The hardness of sapphire is second only to that of diamonds. Technology manufacturers can purify its elements and apply them to some transparent glass panels, which can achieve better hardness performance than traditional chemically strengthened glass. Therefore, sapphire screens have broad application prospects. Nowadays, metal mobile phone casings are also becoming more and more popular, so the technology of combinin...
