The circuit board is an important electronic component, is a support body of the electronic component, and is a carrier for electrical connection of the electronic component. The printed boards have evolved from single-layer to double-sided, multi-layer and flexible, and still remain the trend for each. Due to the continuous development towards high precision, high density and high reliability, the volume is continuously reduced, the cost is reduced, and the performance is improved, so that the printed board still keeps strong vitality in the development engineering of future electronic equipment.

The solder paste is a homogeneous mixture of alloy solder powder, pasty flux and some additives, and has certain viscosity and good thixotropy. It is a homogeneous, stable mixture. The soldering paste can initially stick the electronic component at a preset position under normal temperature, and when the soldering paste is heated to a certain temperature, the soldering paste flows again along with the volatilization of the solvent and part of the additives and the melting of the alloy powder, so that the soldered component and the soldering pad are interconnected together and form a permanently connected soldering point after being cooled.

At present, when using solder paste, scrape through brush, cotton swab or soldering tin rifle and get solder paste mostly, the temperature of soldering tin rifle is high, causes the solder paste in the solder paste box easily rotten, brings inconvenience for scraping to get solder paste. Therefore, the solder paste scraping device for circuit board production is provided.
