The thickness of the solder wire refers to the diameter of the solder wire, which belongs to the scope of the solder wire specifications. In the manufacturing process of the solder wire, there is a process of extrusion and drawing, which determines the diameter of the solder wire. When ordering the solder wire, selecting the appropriate diameter of the solder wire is also one of the factors that effectively improve the welding efficiency.

Solder wire diameter common wire diameter is 1.2mm, 1.0mm, 0.8mm, different wire diameter size in the production process is not the same complexity, the thickness of the wire diameter is selected properly, one is to save the cost of solder, two can also improve the efficiency of welding and welding quality. If the welding process is drag welding, you can not choose too thin solder wire, 0.6mm-1.0mm or so will be more suitable, too thin solder wire solder machine welding tin will be more troublesome, affecting the welding speed. If it is welding patch resistance, capacitor or repair welding IC foot, you can choose according to the size of the components.

In the actual product welding, if the printing line of the computer motherboard is very thin, it will be easier to control when welding with a thinner solder wire, and the solder joint will be more beautiful. If the electronic circuit or line is thick, it is necessary to use a thicker solder wire, and order the appropriate diameter solder wire according to the actual situation. In addition, when welding, if the electric soldering iron power is high, the working temperature is correspondingly high, the range of solder wires that can be welded is relatively large, and the thicker solder wire will be better welded and the welding is smooth. There is no specific hard and fast rules for selecting the thick solder wire, which can be selected according to the use habits, or according to the size of the solder joint of the product to be welded, or according to the size of the component and the welding process.

The wire diameter of the solder wire is divided into 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm,2.0mm, etc., according to the thickness of the solder wire diameter, the conventional use of the solder wire diameter is 0.8mm and 1.0mm, which is suitable for most electronic products, components welding; Under normal circumstances, 0.8mm, 1.0mm solder wire is more widely used, when you do not know what thickness of solder wire to choose, choose these two kinds of thickness of solder wire are generally applicable.

Here we want to explain that the diameter of the solder wire also determines the price of the solder wire, which is mainly due to the production process of the solder wire. Generally speaking, the finer the solder wire in the production process is complex, the higher the price. Therefore, we must consider comprehensively when choosing the diameter of the solder wire, and choose the tin wire that is suitable for product welding, workers' operating habits and cost budgets.
