Lead-free solder wire is a kind of solder wire, also known as environmentally friendly solder wire, because this solder wire does not contain lead, so the use of this solder wire will not cause pollution to the environment. When we do electronic welding, lead-free solder wire solder wire and soldering iron together, the composition of the solder wire and the quality of the solder wire are inseparable. So what should we pay attention to when using lead-free solder wire? This article will summarize the points for attention when using lead-free solder wire.

First of all, in the use of lead-free solder wire, should be careful not to touch the ground area with your hands, that charging, including the welding pen cover do not touch, may be electric shock. Operators should also wear protective clothing as much as possible, as the liquid nature of the solution is produced during the welding process, which can easily be scalded without protective clothing.

Lead-free solder strips are made of high purity alloy and are deoxidized in vacuum under strict quality control standards to effectively control the degree of oxidation and the content of new and non-metallic substances. Solder surface symmetry, smooth, high purity, good fluidity, good wettability, bright solder spot, rarely oxidized slag. Suitable for all kinds of peak height or manual welding process.

High oxidation resistance lead-free solder bar:

At the welding temperature below 300℃, the surface of the liquid energy solder is mirror-like, the wetting time is short, and the expansion rate exceeds that of the ordinary lead-free solder. Because of the added oxidation resistance, bright and beautiful solder joint, suitable for wave soldering and hot dip welding of PCB.

The above is a summary of the matters needing attention in the use of lead-free solder wire. I hope you can use it in the future when using the solder bar.
