Product Application
Solder materials are indispensable in the production and maintenance work of the electronics industry. Generally speaking, the commonly used solder materials are tin-lead alloy solder, twisted solder, cadmium solder, silver solder, and copper solder.
The wire solder used in standard soldering operations is called Rosin core solder wire or solder wire. Solder is added to the solder. This flux consists of rosin and a small amount of active agent.
The temperature setting during welding is very important. The most suitable temperature for welding work is the melting point of the welding used + 50 degrees. The setting temperature of the iron head, due to the size of the soldering part, the power and performance of the soldering iron, the type of solder, and the type of wire, should be increased by 100 degrees on the basis of the above temperature.
The main products of solder are divided into three categories: solder wire, solder strip and solder paste. Applied to all kinds of electronic welding, suitable for manual welding, wave soldering, reflow soldering and other processes.
Raw material production
High-quality and high-purity tin ingot raw material fusion electrolysis special refining process, low welding speed, low residue, wettability, good conductivity and thermal conductivity
Low residue, high insulation resistance
Less residue after welding, transparent appearance, high insulation resistance, no corrosion of PCB, can meet the requirement of no-clean
Moderate viscosity, no slump, no offset
Long time of continuous printing, no collapse within a few hours after printing, small changes in viscosity, and less likely to cause chip components to shift.
Strong wettability, good performance
Good wettability, excellent welding performance, good ICT test performance, no misjudgment.
