When welding the solid core solder wire, the temperature of the iron head should be accurately controlled. At present, due to the substantial improvement of the production process, most factories will choose rosin core tin wire, mainly because rosin core tin wire itself contains flux, the flux content is usually tested and deployed repeatedly, suitable for general manual welding and machine welding, rosin core tin wire can be adjusted according to the welding product is manual welding or machine welding rosin content in the tin wire. The welding double rate element is higher than the solid core tin wire, mainly used for SMT patches, embedded components after repair, wires, embedded chips, electronic components, precision products manual or machine automatic welding.

Solder wire is widely used, especially in all aspects of manufacturing and life. Let's have a more detailed introduction below

Solder wire is used to weld the tin wire, tin wire clarify its composition must contain tin. Generally, the metal composition of tin wire includes tin, lead, silver, copper, bismuth, antimony and other metal components. In the meantime to tin silver copper, tin copper, tin lead composition of solder wire, the market is more commonly seen is these kinds of solder wire. The good and bad of the solder wire has a very big impact on the finished product. How to determine the good and bad of the solder wire and how to determine the quality of the solder wire?

Solder wire is composed of solder alloy and flux two parts, when the solder wire melted by ferrochrome and flux at the same time did occur chemical changes, the occurrence of smoke is the process of flux heated evaporation, some people will say that does not add flux is not smoke, the answer is no flux wire is not smoke. The following share solder wire smoke causes and solutions

The effect of weather on lead-free solder wire and proper preservation and use

The difference between spot welding and drag welding of solder wire and the lead content of lead-free solder wire are introduced in detail

The main problems in the production process are as follows

Vacuum smelting stir-frying adopts 1GB frequency conversion and power regulation, which can quickly dissolve various metals for 24 hours with full load. The highest temperature can reach 2600 degrees, and the fastest can dissolve a furnace in two minutes. The 38V three-phase GB 5-wire power line is safe and reliable, and the high stable heating system and reliable quality inspection protection function make the whole equipment more durable. Under the protection of vacuum and inert gas, the problems of metal oxidation and irregular corrugations of metal contraction in melted gold or silver are solved.

Tin wire is a kind of alloy solder. High-quality tin wire is the key factor for improving production efficiency. It is also critical when purchasing tin wire. There are several points that must be paid attention to, as follows:

1. Yellow solder joints appear after tinning on the tin wire: this phenomenon is caused by excessive soldering temperature, you should immediately check the temperature of the tin furnace or the temperature of the soldering iron tip and whether the thermostat is faulty;
