    I don't know what solder paste is for and how to use it. Write how to use it better!

    Welcome,
    solder paste is used for soldering.
    It can be stenciled onto a printed circuit onto which surface mount components are placed, and then soldered in a reflow soldering oven.
    The paste can also be applied with a syringe, puppet, etc. in the case of repairs of electrical devices, and then solder the system with a Hot-Air soldering iron (hot air) (by desoldering the damaged one).
    The paste consists of a flux and a powdered mixture of tin, lead, gold, silver, copper - the composition is given on the packaging.

    greetings

    Generally speaking, solder paste is a flux that prevents oxidation of the brazed surface and facilitates solder wetting.
    The paste may have powdered solder, but there are some that do not.

    How to use? It all depends on what you want to solder.
    As for example with copper pipes, apply the paste with a brush to the cleaned surface and then with a heater.

    It is used for soldering. Contains hydrochloric acid. Sometimes solder elements on the boards. After soldering, rinse with water. There are short circuits between the paths on the board and therefore we rarely use it in electronics.

    Hydrochloric acid???
    I think that the time when solder pastes in electronics contained this compound has passed ... unless we use it to solder metal gutters but it's probably not this section ...

    We have no idea what Kumek meant.
    The question is general, the answer is also.

    The solder paste facilitates soldering, e.g. when whitening the wires, it allows the tin to be evenly distributed over the whitened tip
    When soldering slotted elements, it significantly improves the adhesion and appearance of the solder, the tin does not pull behind the tip

Topic summary

Solder paste is a crucial material used in soldering, particularly for surface mount components on printed circuit boards (PCBs). It consists of a flux and a powdered mixture of metals such as tin, lead, gold, silver, and copper. The paste can be applied using stencils or syringes and is essential for ensuring proper adhesion and preventing oxidation during the soldering process. For applications like copper pipes, it is applied with a brush to cleaned surfaces before heating. While some pastes may contain harmful substances like hydrochloric acid, modern electronics solder pastes typically do not. Proper use of solder paste enhances the quality of solder joints and prevents issues like short circuits on PCBs.
