A method for improving welding performance of 5g communication module

Abstract

The invention discloses a method for improving the welding performance of a 5G communication module, which comprises the following raw materials by weight: 11% of solder paste and 89% of tin powder, wherein the mass percentage of the solder paste contains 35%-40% of Rosin, 40%-45% solvent, 2%-3% thixotropic agent, 5%-10% active agent, 1-2% corrosion inhibitor, 0.5%-1% surfactant and 1- 2% polyazide glycidyl ether modified substance, when preparing the method to improve the welding performance of 5G communication module, the modified material is mainly added to the solder paste part, and then the solder paste is mixed with the solder paste and tin powder to make the solder paste. The quantitative components of rosin, solvent, thixotropic agent and modified additive are heated and stirred evenly, so that the mixture can release heat during the welding process and increase the temperature inside the shielding cover of the module, which can effectively improve the welding caused by the temperature inside the shielding cover. Poor performance, especially the false soldering problem of the module, can obtain the welding effect of good wetting and bright and full solder joints.

Description

technical field

[0001] The invention relates to a method for welding performance, in particular to a method for improving the welding performance of a 5G communication module, and belongs to the field of conformal paint for 5G communication modules. Background technique

[0002] 5G mobile networks Like earlier 2G, 3G and 4G mobile networks, 5G networks are digital cellular networks in which the service area covered by a provider is divided into many small geographic areas called cells. Analog signals representing sound and images are digitized in mobile phones, converted by analog-to-digital converters and transmitted as a bit stream. All 5G wireless devices in the cell communicate via radio waves with the local antenna array and low-power automatic transceivers (transmitters and receivers) in the cell.

[0003] However, at present, most of the current attention is on the solderability of solder paste, but an important issue is ignored, which is the problem of temperature d...
