摘要：A halogen-free solder paste and a preparation method therefor. The halogen-free solder paste compris 80-90 parts by weight of an Sn-X alloy powder, 0.5-1.5 parts by weight of a halogen-free activator, 2-4 parts by weight of an organic solvent, 3-5 parts by weight of a liquid rosin resin, 0.5-1 part by weight of a thixotropic agent, and 0.05-0.5 part by weight of a leveling agent. The influence of halogen on the weldability after welding is avoided; few residues remain after welding; and the halogen-free solder paste does not need to be cleaned, is environmentally friendly and non-toxic, is relatively low in cost and has a very strong market competitiveness. By virtue of the good adhesion between the halogen-free solder paste and a welding substrate, the problem of the poor welding performance of the conventional solder paste can be effectively solved.
