The invention relates to a high-temperature lead-free soft solder and a preparation method, which belong to the soldering technology for electric encapsulation. The material components counted by the weight percentage are as follows: 2 to 8 percent of stibium, 2 to 12 percent of tin, 0.5 to 5 percent of copper and the rest is bismuth. The melting point of the high-temperature lead-free soft solder is between 250 and 450 DEG C; besides, the high-temperature lead-free soft solder has the advantage of good spreading and wetting performance, high intensity and good corrosion resistance; the high-temperature lead-free soft solder can adapt the demands of various technologies, environments and artificial factors in the electron industry which is continuously developed.
