Solder paste manufacturers explain: What is the general content of solder wire?

Generally speaking, solder wires are divided into two types, which everyone should be quite clear about. Different types of solder wires have different tin contents. Among them, the main components of lead solder wires are lead and tin. Therefore, for many industries, they are also different, and the products used may be different. Now, JJY solder Paste will take you to understand:

The common classifications of solder wire include leaded solder wire and lead-free solder wire

1Common specifications of leaded solder wire include

63tin/37Lead60tin/40Lead55tin/45Lead50tin/50Lead45tin/55Lead40tin/60Lead35tin/65Lead30tin/70Lead25tin/75Lead, tin20/lead80Tin15/lead85.

2Common specifications of lead-free solder wire include

99.3tin-0.7Copper, tin-0.3silver-Copper96.5tin-3.0silver-0.3Copper, tin-3.0Silver, anode rod99.9tin

Regarding the tin content of solder wire, there is actually a standard within the industry. No matter what ratio of solder wire is used, for instance, the ratio of tin to lead in lead-containing solder wire has been strictly tested, and the content standards of tin and lead cannot exceed this standard. Moreover, the production process of solder wire is not only limited to these two components of tin and lead, but also includes some other fluxes and so on. Apart from the main components of solder, the flux also plays a significant role in determining the price of solder wire and its usability. Additionally, there are differences in the production processes of each solder manufacturer, as well as subtle variations in the processes.

Nowadays, many industries choose lead-free solder wire. Why? To meet environmental protection requirements, the proportion of tin content in solder wire is as follows:63tin/37Lead60tin/40Lead55tin/45Lead50tin/50Lead45tin/55Lead40tin/60Lead35tin/65Lead, etc., because the price of tin is the same as that of lead6It is about twice as much, so the higher the tin content, the better the price;In addition, for pure tin solder wire, the tin content can reach99.3%The higher the purity, the more environmentally friendly it is and does no harm to the body.

The above is a brief explanation of some small knowledge for everyone. You can take a look and have a clear understanding when using the product. Therefore, it is recommended that when choosing a product, you should also match the product to be welded and its quality before making a purchaseSolder wireIf you still have any questions, please keep following JJY Solder Paste Manufacturer's online message to interact with us for knowledge about soldering!
