[0018] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0019] Please refer to Figures 1 - 3 , this utility model provides a technical solution: a highly stable solder ball, including: a first tin layer 1, an anti-oxidation layer 2 is coated on the surface of the first tin layer 1, a static electricity layer 3 is fixedly installed inside the first tin layer 1, and a second tin layer 4 is fixedly installed inside the static electricity layer 3.

[0020] Specifically: the anti-oxidation layer 2 coated on the surface of the first tin layer 1 makes the entire solder ball have good anti-oxidation performance, making the solder ball more perfect. The static electricity layer 3 absorbs the static electricity generated during the use of the solder ball, making the welding effect better.

[0021] In one embodiment, the material of the antioxidant layer 2 is a nickel coating.

[0022] Specifically: The antioxidant layer 2 coated on the surface of the first tin layer 1 is made of a nickel coating. Plating nickel on the surface of the first tin layer 1 can provide it with good antioxidant properties. Nickel is relatively stable in the air and can effectively prevent the underlying metal from being oxidized. At the same time, nickel has good solderability and can be well combined with the solder during the welding process, without having a negative impact on the welding effect, enabling the solder balls to have better antioxidant properties when not in use. During use, due to the solderability of nickel, the solder balls can be welded better, making the welding more stable.

[0023] In one embodiment, the surface of the static electricity layer 3 is fixedly installed on the inner wall of the first tin layer 1, and the inside of the static electricity layer 3 is fixedly installed on the surface of the second tin layer 4. The material of the static electricity layer 3 is a carbon fiber composite material.

[0024] Specifically: During the process of using the solder balls for welding, since the material of the static electricity layer 3 is a carbon fiber composite material, carbon fiber itself has good electrical conductivity. The carbon fiber composite material formed by combining it with a suitable resin matrix can help the heat to be evenly distributed during welding, improving the quality and efficiency of welding. According to the carbon fiber composite material, static electricity can be effectively conducted and dissipated, reducing the impact of static electricity during welding and minimizing the harm to the welded components, making the welding of the solder balls more stable.

[0025] In one embodiment, circular holes 5 are equidistantly opened inside the first tin layer 1, circular holes 5 are equidistantly opened inside the static electricity layer 3, and circular holes 5 are equidistantly opened inside the second tin layer 4.

[0026] Specifically: Through the multiple circular holes 5 opened inside the first tin layer 1, the static electricity layer 3, and the second tin layer 4, when the solder balls are heated and melted, the contact area between the solder balls and the heat is increased, enabling the solder balls to melt more quickly and facilitating the welding process more rapidly, making the welding of the solder balls more convenient and faster.

[0027] In one embodiment, a protective layer 6 is fixedly installed on the surface of the inner wall of the circular hole 5, and the material of the protective layer 6 is low-melting-point glass powder.

[0028] Specifically: While the circular hole 5 expands the heating area, due to the material of the protective layer 6 fixedly installed on the surface of the inner wall of the circular hole 5 being low-melting-point glass powder, it has good antioxidant properties. During the process of using the solder balls for welding, the low-melting-point glass powder melts at a certain temperature and fuses with the solder, reducing the surface tension of the solder and promoting the spreading and wetting of the solder on the metal surface to achieve fluxing. At the same time, after the low-melting-point glass powder is fluxed, the glass layer can isolate the air, further preventing the oxidation of the welded area, making the welding effect of the solder balls faster and better, and making the solder balls more perfect.

[0029] Working principle: When the solder ball is in use, the antioxidant layer 2 coated on the surface of the first tin layer 1 is made of nickel coating. Plating nickel on the surface of the first tin layer 1 can provide good antioxidant performance. Nickel is relatively stable in the air and can effectively prevent the first tin layer 1 inside the antioxidant layer 2 from being oxidized. At the same time, nickel has good solderability and can be well combined with the solder during the welding process without having a negative impact on the welding effect, enabling the solder ball to have better antioxidant properties when not in use. During use, the solderability of nickel enables the solder ball to be welded better, making the welding more stable. The electrostatic layer 3 fixed between the first tin layer 1 and the second tin layer 4 is made of carbon fiber composite material. Carbon fiber itself has good electrical conductivity. The carbon fiber composite material formed by compounding it with a suitable resin matrix can help the heat be evenly distributed during welding, improving the quality and efficiency of welding, effectively conducting and dissipating static electricity according to the carbon fiber composite material, reducing the impact of static electricity during welding, reducing the harm to the welded components, making the welding of the solder ball more stable, thereby enabling the solder ball to have better antioxidant properties and being able to dissipate static electricity during the welding process, making the welding effect of the solder ball more stable; during welding, through the multiple circular holes 5 opened inside the first tin layer 1, the electrostatic layer 3 and the second tin layer 4, when the solder ball is heated and melted, by increasing the contact area between the solder ball and the heat, the solder ball can be melted and welded faster, making the use of the solder ball more convenient and fast. The protective layer 6 fixed on the surface of the circular hole 5 is made of low melting point glass powder. According to its good antioxidant property, during welding, the low melting point glass powder melts at a certain temperature and fuses with the solder, reducing the surface tension of the solder, promoting the spreading and wetting of the solder on the metal surface, achieving fluxing, and making the welding effect of the solder ball better and more perfect.

[0030] The above is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
