Embodiment 1
[0021] A material is added in the preparation process of the solder paste, and the obtained solder paste is uniformly mixed with the tin powder to prepare the solder paste;
[0022] The operation steps of the method for improving the welding performance of a 5G communication module are as follows:
[0023] Step 1: heating and stirring the quantitative components of rosin, solvent, thixotropic agent and modification additive to obtain a mixture;
[0024] Step 2: Add the active agent of quantitative components to the mixture, heat and stir evenly, and then cool to room temperature to become a flux paste;
[0025] Step 3: Put the flux paste and tin powder into the solder paste mixer, heat and stir evenly to get the solder paste.
[0026] As a technical optimization scheme of the present invention, it is composed of the following raw materials by weight: 11% of solder paste, 89% of tin powder, wherein the mass percentage of the solder paste contains 35%-40% rosin, 40%-45% % of s...
Embodiment 2
[0033] Based on the method for improving the welding performance of a 5G communication module provided by the first embodiment of the present invention, the method for improving the welding performance of a 5G communication module provided by the second embodiment of the present invention is different in that the solder paste includes the following raw materials by mass percentage: Soldering paste 11% (wherein the soldering paste includes the following mass percentage materials, 40% rosin, 43% diethylene glycol dibutyl ether and ethylene glycol butyl methyl ether, 4% hydrogenated castor oil, 9% hexane Diacid and stearic acid, 2% benzotriazole, 1% OP-10 and 1% terminal azide polyazide glycidyl ether), tin powder 89%, rosin in the solder paste It accounts for 40% of the solder paste, which can effectively improve the poor soldering performance caused by the temperature in the shield, especially the false soldering problem of the module.
Embodiment 3
[0035] Based on the method for improving the welding performance of a 5G communication module provided by the first embodiment of the present invention, the method for improving the welding performance of a 5G communication module provided by the third embodiment of the present invention is different in that: the solder paste includes the following raw materials by mass percentage: Soldering paste 11% (wherein the soldering paste includes the following mass percentage materials, 41% rosin, 43% diethylene glycol dibutyl ether and ethylene glycol butyl methyl ether, 4% hydrogenated castor oil, 9% hexane Diacid and stearic acid, 2% of benzotriazole, 1% of OP-10), 89% of tin powder, using the above scheme to prepare the modified material in the solder paste can release heat during the welding process, improve the module Temperature inside the middle shield.
