Description:

• The solder wire used for the soldering of the manual electronic device is composed of a tin alloy and an auxiliary agent.

• In the electronic soldering, the solder wire is matched with the soldering iron, and the high-quality soldering iron provides stable and continuous heat of fusion, and the solder wire serves as a filler.

• The metal is added to the surface and the gap of the electronic original device, and the fixed electronic original device becomes the main component of the solder.

• The composition of the solder wire is inseparable from the quality of the solder wire, which will affect the chemical properties, mechanical properties and physical properties of the solder wire.

• Different types of solder wire additives are different. The auxiliary part is to improve the heat conduction of the solder wire during the welding process, remove the oxidation, reduce the surface tension of the material to be welded, remove the oil stain on the surface of the welded material, and increase the welding area.

Precautions:

• Keep away from children.

• Avoid contacting with eyes.

• Avoid repeated contact with skin.

• Avoid repeated breathing of vapor. (Use only with adequate ventilation.)

• In order to be cautious, in the operation, the smoke released by the solvent during operation should be avoided as much as possible, and the skin and mucous membrane tissues should not be contacted for too long.

Attention please:

• The measurement allowed error is ±1.0-2.0cm.

• Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
