As everyone knows,Solder paste manufacturerThe solder paste, solder wire and solder bar produced are commonly used raw materials in the soldering process of the entire electronics industry. How should the three be selected?JJYThe solder paste manufacturer will give a brief introduction to the partners:

    Solder pasteThe differences between solder bars and solder wires.

Judging from their appearance, the differences among the three are quite obviousSolder pasteIt is a viscous commodity made of tin-aluminum alloy and appears grayish-white. Solder paste is generally sold in the bottled market, with each can weighing 500 grams. Tin bars are strip-shaped products, one piece at a time, mainly in cans, with each case weighing around twenty kilograms. The solder wire is rolled up and looks like a thin iron wire.

From the perspective of composition, solder paste is mainly composed of tin powder, flux and surfactant, and can be applied throughout the entire soldering process. In the early stage, solder wire does not use flux. Today, flux has also been added to the tin wire, allowing for direct soldering. Unlike solder paste and solder wire, solder bars are made of pure tin and do not use flux. Therefore, when using a wave soldering machine, flux must be added at the front.

    Solder paste, solder bars and solder wires are all key raw materials required for soldering and play a crucial role in their respective industries.

    Solder paste is generally moist and contains flux components, which can prevent oxidation. It is mainly used forSMTSurface mount technology, laser welding.

    Tin strips are generally suitable fordipWeldingDIPWelding and wave soldering machines. They have the characteristics of good moisture resistance, good fluidity, easy tin plating, bright and round spot welding, and avoiding strong oxidation. Since the tin bars are made of pure tin, there is less tin slag, which can increase the utilization rate.

    Tin wire generally does not have flux, and the flux for different types of tin wire varies. It is mainly applicable to soldering irons, electric soldering irons, laser welding, etc., and is heated during tin feeding. It should be noted that only tin wires with corrosion agents are suitable for soldering electronic components, as they do not have moisture and plasticity, and soldering can cause spatter

    Nowadays, solder paste, solder bars and solder wires have been widely usedSMTCommunication equipment, computers and other electronic devices, whether it is welding, wave soldering machines, reflow soldering ovens or packaging and printing, they are the welding materials that are widely used in the current sales market.

    It is firmly believed that in the future development trend, solder paste, solder bars, solder wires, etc. will also be applicable to the soldering work of a large number of electronic components.Shenzhen JJY Industrial Technology Co., LTDConcentration12We have been engaged in the research and development and sales of the soldering industry for many years, providing customers with complete electronic soldering solutions.
