How SMT solder paste is mixed. Is there any quick way?

The solder paste should be fully stirred before using
Purpose: To make the flux and tin powder evenly distributed, give full play to various characteristics;
Mixing method: manual mixing or machine mixing can be; mixing time: manual: about 4 minutes machine: 1 ~ 3 minutes
1) Manual Mixing: Remove the solder paste from the freezer and open the cover until it returns to room temperature (about three to four hours at 25 ° C). Stir the solder paste with a stirring knife. If the cover is broken, tin The cream will become tin pieces by absorbing moisture.
2) with automatic mixer:. If the solder paste is removed from the freezer, there is only a brief warm-up period and you will need to use an automatic mixer to use automatic mixing without affecting the solder paste characteristics. After a period of agitation, the solder paste will. Gradual warm-up If the mixing time is too long, it may cause the solder paste to be higher than the operating room temperature, causing the solder paste to be poured over the board in one piece, and flow (bleeding) during printing, so be careful. Due to different machines, room temperature and other conditions change, will result in different mixing time, so before proceeding, please prepare enough test.
Stirring effect of the judge: Scraping part of the solder paste with a scraper blade tilt, if the solder paste can slide down smoothly, that is, the right to meet the requirements of the appropriate mixing time due to the mixing method, the device and the ambient temperature and other factors vary, should Do more experiments in advance to determine.

We have a fully automatic tin paste mixer which can solve these problems:
