Lead-free tin wire appears to be made of secret medicine flocs in appearance, and its melting point is217-227Lead-free tin wire has a light yellow luster and color. When you rub the tin wire with your hand, it leaves a light yellow mark because lead-free tin wire usually contains copper metal materials. The outer packaging box of lead-free tin wire is a small emerald green box, and each roll of tin wire is wrapped in a low-carbon and environmentally friendly packaging paper box.

Lead-free tin wireAlso known as environmental protection tin wire, its main component is: tinSnSilverAgCopperCuThere is a small amount of lead in others.PbMercuryHgCadmiumCdPolybrominated biphenylsPBBsEtc. Lead-free tin wire was mentioned to integrate into the environmental protection regulations of EU countriesROHSThe standard stipulates that the lead content is specified1000PPM In other words, equipment that exceeds this specification is not in compliance with energy conservation and environmental protection regulations. It is specifically divided into three component standards: basically lead-free environmentally friendly tin wireSn99.3Cu0.7;3A silver lead-free environmentally friendly tin wireSn96.5Ag3.0Cu0.5;0.3Silver lead-free environmentally friendly tin wireSn99Ag0.3Cu0.7. As shown in the following figure:

Lead-free tin wire

The electric soldering operation method for lead-free tin wire is the same as that for leaded tin bars. It mainly needs to be used in conjunction with special soldering iron tools or fully automatic soldering equipment. The temperature management method of the soldering iron tip during tin wire electric soldering is very important. Select the appropriate soldering iron tip and temperature setting. Generally, manual electric soldering is carried out with temperature-controlled soldering iron equipment. A suitable soldering iron tip can reduce the temperature of the soldering iron tip and improve work efficiency. Before starting work, use a soldering iron tip thermometer to measure the temperature of the soldering iron tip first. Use a genuine soldering iron tip that is compatible with the manufacturer. The set temperature for lead-free tin wire welding operations is generally adjusted to350Degree of－370In addition, when purchasing lead-free tin wire, it is necessary to choose from professional manufacturers to ensure better quality. Environmental protection tin wire

The main component of lead-free tin bars is the same as that of lead-free tin wires. However, the lead-free tin bars produced from the outside are in the shape of strips, one by one, without solder paste,All are used forpcbElectric welding of circuit boards,When applied in wave soldering machines or soldering furnaces, it should be used in conjunction with flux paste. The lead-free tin bars produced by Double Dominican have a bright surface after melting, a smooth and elegant appearance, and less sediment, reducing unnecessary consumption. The moisture time is relatively short, the expansion rate is high, and the effect of the solder wire is very good. High-purity electrolysis method, with the addition of an appropriate amount of antioxidant elements, has strong antioxidant properties; The air oxidation impurity is less, which can reduce the sharpening condition. Strictly abide by the EU countriesROHSThe command is reliable and of guaranteed quality. As shown in the following figure:
