Manufacturing technology for tin wire production

Abstract

The invention discloses a manufacturing technology for tin wire production, and relates to the technical field of tin wire production. The manufacturing technology is aimed at solving the problems inthe prior art that as lead-free tin wires have relatively low lead content inside due to the requirements of the manufacturing technology, the gloss of welding spots of the lead-free tin wires is excessively dark, and when the lead-free tin wires are used in certain environments, the overall aesthetic property is affected. The manufacturing technology comprises the following steps of: step one. preparing a certain proportion of tin, silver, and copper raw materials according to the actual processing requirements, and meanwhile preparing certain trace amounts of lead, mercury, cadmium, and polybrominated biphenyl materials; step two. preparing an electric melting furnace required for smelting, and then putting the tin material and other auxiliary materials into the electric melting furnaceaccording to the corresponding proportion until the raw materials are smelted into liquid; and step three. after smelting the raw materials, pouring an antioxidant into a smelting furnace containing the raw materials, and then increasing the temperature of the smelting furnace and agitating slightly to cause the raw materials to completely melt.

Description

technical field [0001] The invention relates to the technical field of tin wire production, in particular to a manufacturing process for tin wire production. Background technique [0002] Solder wire, Chinese name: solder wire, solder wire, tin wire, tin wire, English name: solder wire, solder wire is composed of tin alloy and additives, and the alloy composition is divided into tin-lead and lead-free additives. To the middle part of the tin alloy, different types of solder wire have different additives. The additive part is to improve the auxiliary heat conduction of the solder wire during the welding process, remove oxidation, reduce the surface tension of the material to be welded, remove the oil on the surface of the material to be welded, and increase welding area. The characteristic of solder wire is tin alloy wire with a certain length and diameter. It can be used in conjunction with electric soldering iron or laser in the welding of electronic original devices. The ...
