The solder paste itself is also a viscous shape that is uniformly combined with uniform solder alloy powder and reliable flux, and can form an alloy material connection during soldering. This substance is very suitable for the safe and reliable welding of automatic production of surface mount. It is a high-tech product of the modern electronics industry. Let's discuss it together with the following solder paste manufacturers:

As a related electronic material, solder paste is not only a new material technology itself, but also an old material before. With the continuous development of high performance, miniaturization and multiple uses of computers, electronic equipment, and household appliances, the past manual soldering and subsequent wave soldering have been unable to meet such development needs, so it has developed to today's SMT. That is what follows in such a situation. In terms of the main application fields today, solder paste is generally divided into two forms: laser spot welding and printing.

Considering the strong plasticity of solder paste, it can also be welded to many parts that are difficult to solder with solid solder. The application of solder paste is very wide. Application examples. Solder paste is especially suitable for soldering metal parts in purely mechanical parts, such as heat pipes, fishhooks and sealing joint types on fluid control machines. In the electromechanical industry, solder paste is suitable for welding lines and cable parts, and connecting cables with strong strengtheners, etc. The application of solder paste in the electrical industry includes the production and processing of pcb circuit boards and electronic components, which can cover all the smart electronic products you know-from small toys to digital watches, from calculators, smartphones to the fastest computers.

Components and basic features of solder paste Solder paste is a rather complex substance, consisting of flux paste and alloy powder. Solder paste is regarded as a high-density suspension, and the volume ratio of solid (metal particles) to liquid (flux paste) is 50% to 50%, which can be considered to be a uniform composition. From a rheological point of view, one state of solder paste is dense alloy powder dispersed in a non-Newtonian fluid flux carrier.

Alloy material solder powder is the main material of solder paste, and there are also substances after soldering, which play a vital role in the laser welding process of reflow soldering equipment, the height of solder joints, and the safety and reliability. According to the actual needs of the welding object and the specific laser welding process, the composition, particle shape and size of the alloy material solder powder are important factors that affect the basic characteristics of the solder paste. Flux is a key material for purifying soldering surfaces, improving wettability, preventing solder oxidation and ensuring safe and reliable solder joints.
