How to choose lead tin wire and lead-free tin wire

2017-02-28 08:37

Lead-free tin wire plays an important role in our life. In modern development, many tools play a more or less driving role, and lead-free tin wire is undoubtedly one of them. We all know that iron has a certain conductive function, and lead-free tin wire can also conduct electricity. And the lead-free solder wire is inside the solder wire, and the conductivity is relatively good and stable. So what are the characteristics of lead-free solder wire? What is the difference between lead-free solder wire and lead-free solder wire? Next, let Yongjiarun Xiaobian take a look at the difference between lead-tin wire and lead-free tin wire and the characteristics and standards of lead-free solder wire.

    The characteristics of Baoda tin industry lead-free solder wire:

    The Yongjiarun lead-free solder wire used for manual electronic component welding is composed of tin alloy and additives. During electronic soldering, the lead-free solder wire cooperates with the electric soldering iron. The high-quality electric soldering iron provides stable and continuous melting heat. First, the lead-free solder wire is added to the surface and gap of the electronic original device as a filler metal, and the fixed electronic original device becomes the main component of the lead-free soldering. The composition of the lead-free solder wire is related to the quality of the lead-free solder wire. Inseparable, will affect the chemical properties and mechanical properties and physical properties of lead-free solder wire.      

The difference between lead tin wire and lead-free tin wire:

    1. Judging from the glossy color of tin appearance: the surface of lead solder looks bright white; while lead-free solder is light yellow.

    2. From the composition of metal alloys: leaded solder is two main metal elements containing tin and lead (such as: Sn63Pb37, Sn50Pb50, etc.); lead-free solder is basically lead-free (the EU ROHS standard is that the lead content is less than 500PPM, the Japanese standard is less than 100PPM), lead-free solder generally contains tin, silver or copper metal elements.

    3. From the point of view of use: lead solder is used for soldering lead products, and the tools and components used in it are all lead. Lead-free solder wire is used for welding products exported to Europe, America and other countries, and the tools and components used in it must be lead-free.

4. If it is distinguished by rubbing by hand: those with lead will leave black marks on the hands, and those without lead will have light yellow marks, because lead-free generally contains copper metal.

Therefore, the choice of lead-tin wire or lead-free tin wire needs to be based on your own product requirements, not lead-free is good! Just fit your product! If you can't choose, you can contact us, Baoda Tin Industry can help you choose and solve the problem, professional tin bar industry.
