Description

Technical Field

[0001] The invention relates to the technical field of solder bar production, and in particular to a slitting device for solder bar production and a use method thereof. Background Art

[0002] Tin soldering rod is a welding rod used for soldering. Tin soldering can be used for sealed metal welding under conditions that do not require high temperature and high pressure. According to the different critical points of the liquidus temperature, solder bars are divided into high-temperature solder bars and low-temperature solder bars. The solder bars with a liquidus temperature higher than the tin-lead eutectic melting point - 183 degrees are high-temperature solder bars. High-temperature solder bars are formed when a high proportion of silver, antimony or lead is added to the solder alloy. High-temperature solder bars are mainly used for component assembly that does not change during motherboard assembly; solder bars with a liquidus temperature lower than the tin-lead eutectic melting point - 183 degrees are low-temperature solder bars. Low-temperature solder bars are formed by adding bismuth, indium and cadmium to the solder alloy. They are mainly used for assembly of parts with low heat resistance such as microelectronic sensors. According to the chemical properties, commonly used types of solder bars include antioxidant solder bars and high-purity low-slag solder bars. Antioxidant solder bars: have good antioxidant ability, high fluidity, strong weldability, very little scum when melted, and very little oxidation during immersion and wave soldering. They are economical solder bars that save tin. Excellent wettability and solderability, full and uniform solder joints, excellent welding effect, high-purity low-slag solder bars: the raw materials used are 100% electrolytic tin, lead or tin-lead alloy, cast or extruded.
