Solder paste is a novel solder material which is generated along with SMT, and is a paste mixture formed by mixing soldering tin powder, soldering flux, other surfactants, thixotropic agents and the like.
The solder paste needs to be refrigerated during storage, and needs to be subjected to tempering treatment before use, wherein the storage temperature of the solder paste is about 5 ℃ and is generally taken out of a refrigerator before use, and then the temperature is returned to room temperature for a period of time, so that the solder paste can be returned to the room temperature for use in a production line for welding the electronic components on the circuit board. If the temperature returning is not completed, the solder paste is opened for use or the temperature returning is insufficient, water and air in the air are condensed and are easy to adhere to the solder paste, and the phenomenon of tin explosion easily occurs when the solder paste passes through a furnace, so that tin beads are generated, the process quality is influenced, and even components are damaged. Therefore, the control of solder paste temperature return is a very important link of SMT process quality.
At present, the solder paste is cooled and placed in a room in a dispersing way. In order to control the temperature return time of the solder paste, the temperature return time of the solder paste is marked in a mode of labeling a solder paste bottle or a solder paste tank; the mode is mainly used for controlling workers, the workers are required to fill in the temperature return time, the labels are checked regularly, and whether the temperature return time of the solder paste is normal or not is judged. Because the solder paste is scattered and placed, visualization is not clear, when a worker takes the solder paste, the temperature return time for taking out the solder paste is not the longest and normal, so that the solder paste with the longest temperature return time is easy to continue to return, and when the solder paste is taken again, the solder paste with the longest temperature return time is possibly overlong, namely the temperature return time is abnormal; or when the solder paste is taken, the manual error of a worker exists, the temperature return time of the taken solder paste is shorter and is less than 4 hours, namely the temperature return time of the solder paste is abnormal.
In the prior art, the controllability of the solder paste tempering time is poor, the tempering abnormality of the solder paste is easily caused, namely, the tempering abnormality of the solder paste is insufficient or the tempering time is overlong, the tempering abnormality of the solder paste is used in reflow soldering, the welding defect is easily caused, the quality of components is influenced, the solder paste cannot be guaranteed to achieve the tempering effect and be reused, and the quality hidden trouble is caused.
Chinese patent CN206263405U discloses a solder paste temperature-returning device, which comprises a temperature-returning box, a first label, a second Wen Dao, a chute, a sliding block, etc.; the right side of the tempering box is uniformly provided with a placing opening from top to bottom, the front sides of the placing openings are respectively and fixedly connected with a first label, the left side of the tempering box is uniformly provided with a taking opening from top to bottom, the front side and the rear side of the taking opening are symmetrically provided with sliding grooves, and when the tempering treatment is required to be carried out on solder paste, staff can write corresponding placing time and taking time on the first label and the second label; the invention needs staff to fill in the temperature return time and immediately check the label to judge whether the temperature return time of the solder paste is normal or not, and the proper temperature return time is easy to miss, so that the temperature return time of the solder paste is abnormal, and the product quality is affected.
