Embodiment 1
[0022] A preparation method of manganese-nickel-cobalt-palladium-gold solder, comprising the following steps: Step 1, according to the composition of Mn 65.4%, Ni 17.11%, Co 12.48%, Pd 2%, Au 1.0%, Ti 1.0% and Al 1.0%. Take each component by weighing, and the balance is impurity components, wherein, the particle size of Mn, Ni, Co, Pd, Ti and Al is 250 mesh; the four components of Mn, Ni, Co and Pd that are weighed are uniformly mixed together, spare;
[0023] Step 2. Put the mixed particles in step 1 into the dry ice alcohol solution, make the temperature of the particles reach -45°C, take out all the particles and put them in a ball mill, and grind them until the particle size is below 30°C under the condition that the particle temperature does not exceed 30°C. When the mesh is 400, stop grinding, wherein the grinding time is not less than 2 hours; then, dry the ground powder at 115°C under a nitrogen atmosphere until its moisture content is lower than 0.05%, and set aside; ...
Embodiment 2
[0031] A preparation method of manganese-nickel-cobalt-palladium-gold solder, comprising the following steps: step 1, according to the composition of Mn 66%, Ni 15.46%, Co 13.62%, Pd 2.5%, Au 0.8%, Ti 0.8% and Al 0.8% Take each component by weighing, and the balance is impurity components, wherein, the particle size of Mn, Ni, Co, Pd, Ti and Al is 400 mesh; then the four components of Mn, Ni, Co and Pd are uniformly mixed together, set aside;
[0032] Step 2. Put the mixed particles in step 1 into the dry ice alcohol solution, make the temperature of the particles reach -50°C, take out all the particles and place them in a ball mill, and grind them until the particle size is below 30°C under the condition that the particle temperature does not exceed 30°C When the mesh is 400, stop grinding, wherein the grinding time is not less than 2 hours; then, dry the ground powder at 110°C under a nitrogen atmosphere until its moisture content is lower than 0.05%, and set aside;

Embodiment 3
[0037] A preparation method of manganese-nickel-cobalt-palladium-gold solder, comprising the following steps: step 1, according to the composition of Mn 61.04%, Ni 19%, Co 14%, Pd 2.33%, Au 1.2%, Ti 1.2% and Al 1.2%. Compare and weigh each component, and the balance is impurity components, wherein, the particle size of Mn, Ni, Co, Pd, Ti and Al is 300 mesh; then the four components of Mn, Ni, Co and Pd are uniformly weighed mixed together, set aside;
[0038] Step 2. Put the granules mixed in step 1 into the dry ice alcohol solution, make the granule temperature reach -55℃, take out all the granules and put them in a ball mill, and grind them until the particle size is below 30℃ under the condition that the granule temperature does not exceed 30℃. When the mesh size is 400, stop grinding, wherein the grinding time is not less than 2 hours; then, dry the ground powder at 113°C under a nitrogen atmosphere until its moisture content is lower than 0.05%, and set aside;
