[0002] Solder balls are widely used in tinplate, flux, organic synthesis, chemical production, alloy manufacturing, and the assembly of multiple integrated circuits in the electronics industry. They are also used as reagents for determining arsenic and phosphates, reducing agents, tin-plated products, etc. High-quality BGA solder balls must have characteristics such as true roundness, brightness, good electrical conductivity and mechanical connection performance, small ball diameter tolerance, and low oxygen content. Solder balls are not only the key materials for connecting different electronic components but also the key factors in promoting the development of electronic devices towards smaller size and higher performance. In order to improve the welding efficiency in the electronics industry, a type of solder ball is required. However, the existing solder balls still have the following deficiencies:

[0003] For example, the utility model with the publication number CN218657413U discloses a lead-free solder ball including a solder ball body and a buffer device. The utility model absorbs the impact force from the collision body through the elasticity of the buffer device to protect the solder ball body. However, for comparative documents similar to the above application, when the existing solder balls are in use, since most solder balls do not have the performance of anti-electromagnetic interference, it is easy to affect the normal use of integrated circuits during the subsequent use of the solder balls, resulting in the problems of decreased practicality and reduced use efficiency of the solder balls.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a solder ball with anti-electromagnetic interference is proposed. Content of the Utility Model

An expansion and contraction adjusting rod is installed outside the shock-absorbing ball, and a return spring is connected to the outside of the expansion and contraction adjusting rod.

[0007] Further, nickel-plated metal layers and antioxidant resin layers are respectively arranged on the inner and outer sides of the solder ball surface layer, and the solder ball surface layer is arranged and restricted between the nickel-plated metal layer and the antioxidant resin layer.

[0008] Further, the internal size of the nickel-plated metal layer is adapted to the external size of the heat insulation layer, and the heat insulation layer is embedded in the nickel-plated metal layer.

[0009] Further, titanium alloy spheres and nickel-plated metal layers are respectively arranged on both the inner and outer sides of the heat insulation layer, and the heat insulation layer is arranged and restricted between the titanium alloy spheres and the nickel-plated metal layers.

[0010] Further, the internal size of the heat insulation layer is adapted to the external size of the titanium alloy sphere, and the inner side of the heat insulation layer is closely attached to the outer side of the titanium alloy sphere.

[0011] Further, the telescopic adjusting rods and the shock-absorbing balls are vertically distributed, and the telescopic adjusting rods are equidistantly distributed outside the shock-absorbing balls.

[0012] Further, the shock-absorbing balls are embedded in the titanium alloy spheres, and the shock-absorbing balls are elastically connected to the titanium alloy spheres through return springs.

[0013] The present utility model provides a tin ball with anti-electromagnetic interference, having the following beneficial effects:

[0014] 1. Through the setting of the nickel-plated metal layer, when the tin ball with anti-electromagnetic interference is in use, the oxidation of the surface of the tin ball can be avoided by the antioxidant resin layer arranged on the outer layer of the tin ball surface after long-term contact with air. At the same time, the nickel-plated metal layer arranged on the inner layer of the tin ball surface can absorb the energy in the electromagnetic field, thereby reducing the intensity of electromagnetic interference received by the tin ball during use. The heat insulation layer is fixedly installed inside the nickel-plated metal layer, and the titanium alloy sphere is protected by the heat insulation layer to avoid damage to the internal components of the titanium alloy sphere caused by high temperature, improving the safety during the use of the tin ball.

[0015] 2. Through the setting of the shock-absorbing balls, when the tin ball with anti-electromagnetic interference is in use, the telescopic adjusting rods are fixedly installed outside the shock-absorbing balls by bonding, and the shock-absorbing balls are elastically connected to the titanium alloy spheres by using the return springs in cooperation with the telescopic adjusting rods.

And the solder ball surface layer 2 is arranged and restricted between the nickel-plated metal layer 3 and the antioxidant resin layer 1. The internal size of the nickel-plated metal layer 3 is adapted to the external size of the heat insulation layer 4, and the heat insulation layer 4 is embeddedly connected with the nickel-plated metal layer 3. On both the inner and outer sides of the heat insulation layer 4, there are a titanium alloy ball core 5 and a nickel-plated metal layer 3 respectively. And the heat insulation layer 4 is arranged and restricted between the titanium alloy ball core 5 and the nickel-plated metal layer 3. The internal size of the heat insulation layer 4 is adapted to the external size of the titanium alloy ball core 5, and the inner side of the heat insulation layer 4 is closely attached to the outer side of the titanium alloy ball core 5. By means of the antioxidant resin layer 1 provided outside the solder ball surface layer 2, the oxidation of the surface of the solder ball after long-term contact with air is avoided. At the same time, the nickel-plated metal layer 3 provided inside the solder ball surface layer 2 can absorb the energy in the electromagnetic field, thereby reducing the intensity of electromagnetic interference received by the solder ball during use. The heat insulation layer 4 is fixedly installed inside the nickel-plated metal layer 3, and the heat insulation layer 4 is used to protect the titanium alloy ball core 5, avoiding damage to the internal components of the titanium alloy ball core 5 caused by high temperature, and improving the safety during the use of the solder ball.
