Soldering paste stirring device for production of computer mainboard

Abstract

The invention discloses a soldering paste stirring device for production of a computer mainboard. The soldering paste stirring device comprises a stirring base; a double-layer stirring barrel with a hollow structure inside is arranged above the stirring base; the upper end of the double-layer stirring barrel is provided with a raw material adding opening; a closed opening cover is arranged at theupper end of the raw material adding opening; and a multistage stirring mechanism, an electric heating mechanism, a vacuumizing device and a shielding gas device are arranged inside the double-layer stirring barrel, wherein the electric heating mechanism is used for heating production raw materials, the vacuumizing device is used for carrying out vacuum treatment on the raw materials in the double-layer stirring barrel, and the protective gas device is used for filling the double-layer stirring barrel with shielding gas. The soldering paste stirring device has the advantages that the stirringeffect is guaranteed, the production quality of the soldering paste is improved, the quality difference of the soldering paste caused by uneven stirring is avoided, and the phenomena that air enters the device, so that a large amount of bubbles are easily generated in the soldering paste, and then the surface mounting effect of the soldering paste during subsequent production of the computer mainboard is influenced can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of computer motherboard production, in particular to a solder paste stirring device for computer motherboard production. Background technique [0002] Computer, commonly known as computer, is a modern electronic computing machine used for high-speed computing. It can perform numerical calculations, logic calculations, and storage and memory functions. It is a modern intelligent electronic device that can run according to programs and process massive amounts of data automatically and at high speed. Equipment consists of hardware systems and software systems. Computers without any software installed are called bare metal, which can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers. More advanced computers include biological computers, Photonic computers, quantum computers, etc., computer motherboards (generally rectangul...

AI Technical Summary

Problems solved by technology

[0004] The stirring operation in the existing solder paste production process is usually simple mechanical stirring directly through the stirring shaft. This method has the problems of poor stirring effect and insufficient stirring, and during the stirring process, air is easy to enter, which is easy to cause solder paste A large number of bubbles are generated in the air, which will affect the placement process of solder paste in the subsequent production process on the computer motherboard
