Flux pasteIt is also a viscous state formed by the uniform mixture of solder alloy powder and reliable flux, which can form a connection of alloy material properties during welding. This substance is highly suitable for safe and reliable soldering in surface mount automated production and is a high-tech product in the modern electronics industry. Let's explore it together with the solder paste manufacturer below:

As an electronic material, solder paste is not only a new material technology in itself, but also an old material in the past. With the continuous development of high-performance, miniaturized and multi-purpose computers, electronic devices, household appliances, etc., the past manual welding and the subsequent wave soldering can no longer meet such development needs, and thus have developed to the presentSMTIt was under such circumstances that it followed. In terms of the main application fields nowadays, solder paste is generally divided into two forms: laser spot welding type and printing type, etc.

Considering the strong plasticity of solder paste, it can also be used to weld many parts that are difficult to weld with solid solders. The application of solder paste is very wide, from its simplest application to rather complex processing techniques, there are typical examples of its application. Solder paste is particularly suitable for welding metal parts in pure mechanical components, such as heat dissipation tubes, fishhooks and sealing interface types on fluid control machines. In the mechanical and electrical industry, solder paste is applicable to the welding of line and cable parts, as well as the strong reinforcement of cable connections, etc. The applications of solder paste in the electrical industry includepcbThe production and processing of circuit boards and electronic components can cover all the smart electronic products you know - from small toys to digital watches, from calculators, smart phones to the fastest computers.

The components and basic characteristics of solder paste Solder paste is a rather complex substance, consisting of flux paste and alloy powder. Solder paste is regarded as a highly dense suspension, with a volume ratio of solid (metal particles) to liquid (solder paste)50%than50%All of them can be regarded as homogeneous compositions in themselves. From a rheological perspective, one state of solder paste is that dense alloy powder is dispersed in a non-Newtonian fluid solder paste carrier.

Alloy material solder powder is the main material of solder paste, and there are also residues after welding. This plays a crucial role in the laser welding process of reflow soldering equipment, the height of the solder joint, and 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 affecting the basic characteristics of the solder paste. Flux is a key material for purifying the welding surface, improving wettability, preventing solder oxidation and ensuring the safety and reliability of the solder joint.
