What are the classifications of solder wire?
2019-12-10
Due to the variety of solder wire specifications, the quality of solder wire directly affects the quality and effect of soldering. Everyone wants to buy good goods! So how to choose to purchase high quality solder wire? Now the editor of Shenzhen Xinghongtai manufacturers will explain to you what types of solder wire there are.
First we must first understand what a solder wire is?
The solder wire is mainly composed of a tin alloy and an auxiliary agent. The composition of the alloy is divided into a tin-lead and a lead-free auxiliary agent and uniformly poured into the center portion of the tin alloy. The types of solder wire are different, and the additives used are different. Some of the additives are used to improve the auxiliary heat conduction of the solder wire during the welding process, remove oxidation, reduce the tension of the surface of the welding material, and remove the oil stain on the surface of the material being welded , Thereby increasing the welding area. The characteristic of solder wire is a tin alloy wire with a certain length and diameter, which can be used in conjunction with an electric soldering iron in the welding of electronic components.
Classification of solder wire specifications:
1. Classified by metal alloy materials, solder wire models can be divided into tin-lead alloy solder wire, pure tin solder wire, tin-copper alloy solder wire, tin-silver-copper alloy solder wire, tin-bismuth alloy solder wire, and tin-nickel alloy solder wire And solder wires made of special tin-containing alloys;
2. According to the chemical composition of the solder wire additives, it can be classified into rosin cored solder wire, disposable solder wire, solid cored solder wire, resin type solder wire, single cored solder wire, three cored solder wire, and water-soluble solder. Wire, aluminum solder wire, stainless steel solder wire;
Third, the solder wire model is classified according to the melting temperature, which can be divided into low temperature solder wire, normal temperature solder wire, and high temperature solder wire.
