The invention relates to the technical field of solder paste production and processing, and discloses a stirring process based on solder paste production. The stirring process is carried out by a solder paste stirring device which comprises a stirring barrel, a stirring shaft, a discharging box, a rack and a motor, wherein the stirring barrel is fixedly mounted on the rack; the stirring shaft is mounted in the stirring barrel; the discharging box is located above the stirring barrel and is fixedly connected with a lower part of the motor; the motor is fixedly mounted on the rack; an airbag isarranged on one side of the stirring barrel; an air cavity communicated with the airbag is formed in the stirring barrel; a dispersing mechanism is arranged on a side wall of the stirring barrel; thedispersing mechanism comprises a fixed base, a rubber bag and an extruding part; an inner cavity communicated with the air cavity is formed in the fixed base; an air outlet check valve with an air outlet toward the stirring shaft is arranged on the fixed base; the extruding part is fixedly mounted on the rubber bag; the rubber bag is communicated with the inner cavity; a material cavity communicated with the discharging box is formed in the upper part of the stirring shaft; a discharge hole is formed in the side wall of the material cavity. The stirring process provided by the invention has agood stirring effect and reduces production of bubbles of solder paste.
