Description

Technical Field

[0001] This utility model relates to the field of solder paste production technology, and in particular to a high-efficiency mixer for solder paste production. Background Technology

[0002] Solder paste is a tin-containing soft paste-like soldering material widely used in the manufacturing of electronic products such as mobile phones, computers and communication equipment. It is an indispensable soldering material in the modern electronics industry. Solder paste production requires the use of a mixer to mix fine solder balls or tin alloy powder with a flux with good flowability. Solder paste may also contain auxiliary ingredients such as thixotropic agents and antioxidants.

[0003] Existing solder paste mixers are inconvenient to quickly connect the mixing tank containing solder paste and auxiliary materials to the mixer during actual use, making material removal very inconvenient. In addition, the mixed material in the mixing tank tends to stick to the inner wall, resulting in poor mixing effect. This paper proposes a high-efficiency mixer for solder paste production to solve the above problems. Utility Model Content
