Novel oxidation-resistant and high-temperature-resistant soldering tin bar

Abstract

The invention discloses a novel oxidation-resistant and high-temperature-resistant soldering tin bar, and relates to the technical field of soldering tin bars. The novel oxidation-resistant and high-temperature-resistant soldering tin bar comprises a soldering tin bar body, the soldering tin bar body is composed of a main body framework and two tin oxidation-resistant reduction powder boxes, the main body framework comprises a U-shaped prefabricated part, clamping grooves are formed in the front side and the rear side of the top of the U-shaped prefabricated part, a soldering flux filling cavity is formed in the inner side of the top of the U-shaped prefabricated part, and the top of the soldering flux filling cavity extends upwards in the vertical direction to form a threaded wall. According to the novel oxidation-resistant and high-temperature-resistant soldering tin bar, an integral structure of a traditional soldering tin bar is split, the tin oxidation-resistant reduction powder boxes and the soldering flux filling cavity are formed inside the soldering tin bar, the soldering tin bar can be filled with the tin oxidation-resistant reduction powder boxes and the soldering flux, therefore when the soldering tin bar is molten, the tin oxidation-resistant reduction powder and the soldering flux can conduct anti-oxidation protection on molten tin, and the timeliness and effectiveness of oxidation resistance can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of solder bars, in particular to a novel anti-oxidation and high temperature resistant solder bar. Background technique [0002] Tin soldering rods are soldering rods used for soldering. When soldering tin rods are used, a part of the tin rods will be placed in the tin tank of the tin melting furnace first, and a part of the tin rods placed in the tin tank will need to be continuously added after melting. When the molten surface of the solder bar reaches a certain height, if there is no solder bar in the soldering furnace, it is necessary to turn off the power of the soldering furnace in time to prevent the tin bath from burning dry. [0003] The solder bar will be oxidized when it comes into contact with the air after melting. The oxidation of the solder bar is inevitable. The existing method usually uses external addition of antioxidant or tin anti-redox powder to slow down the oxidation rate of the solder...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a new type of anti-oxidation and high-temperature resistant solder bar, which solves the problem of poor anti-oxidation effect and inconvenient operation through the use of external auxiliary agents in the traditional solder bar melting process. The melting is not easy to observe, which affects the timeliness of feeding
