What preparations are needed before soldering electronic components?

      Before the welding operation, the welding environment must be cleaned up, the work surface must be clean and tidy, and various welding tools and desoldering tools should be prepared, as well as auxiliary tools such as tweezers, scissors, diagonal pliers, needle nose pliers, solder, flux, And can use these tools correctly.


电子元器件焊接前需要哪些准备工作?    

Prepare the batching components according to the requirements, and check whether the model, specifications and quantity of the components meet the drawing requirements. The choice of solder and the choice of electric iron are very important in the selection of solder in manual soldering. Brazing materials come in various shapes, including filamentous, muddy, spherical, ingot, and various specific shapes, and the shape and specifications of the brazing material are different according to the weldment.

      The wire solder with rosin core is commonly used in manual welding. There are many kinds of solder wire diameters, generally between 0.5 and 3.0mm, and commonly used are 0.5mm, 0.8mm, 1.2mm, 1.5mm, 2.0mm, etc. . In the welding process, we choose solder wires of different diameters according to the actual welding situation. Generally, 0.8 mm or 1 mm solder wire is used for welding electronic components, and 0.6 mm or 0.7 mm diameter solder wire is used to weld small electronic components. Device.

According to the soldering components

    Select the diameter of the solder wire. Choose an electric iron of appropriate power and check the electric iron to ensure that the electric iron is intact and can work normally.

    In addition to this, solderability treatment, lead forming, and component insertion work are also required.
