What is the function of solder wire? What is the melting point? JJY tells you

Solder wire is no stranger to many manufacturers. In the electronics industry, anyone who has worked with products should be familiar with it. However, there are also some who do not understand that during electronic soldering, solder wire works in conjunction with soldering irons. High-quality soldering irons provide stable and continuous melting heat, while solder wire, as a metal filler, is added to the surface and crevices of electronic components. Fixed electronic components have become the main components of soldering. The composition of solder wire is closely related to its quality and will affect the chemical, mechanical and physical properties of the solder wire. So for this aspect, it's better for everyone to have a clearer understanding. Now, JJY solder Paste Manufacturer will explain its functions and features:

Solder wireWhat is its function?

1The function of solder wire is for soldering. It is usually used for soldering electronic components, such as capacitors on circuit boards.ICWelding of components such as resistors. Some special solder wires can also be used to solder stainless steel, so we won't elaborate further.

2Based on the above description, it is not difficult for us to draw the conclusion that solder wire is applied in electronics factories or electrical repair shops.
What is the melting point;

The melting point of solder in general lead-free solder wire is relatively high227℃On the left and right, the melting points of solder wires made of different solder materials do not vary much. Therefore, before using solder wires, it is necessary to first understand how high the temperature your soldered parts can withstand, and then choose lead-free solder wires with appropriate melting points. Several commonly used lead-free solder wire specifications on the market now and their solder melting points.

1tin99.3copper0.7The melting point of solder is227℃It belongs to eutectic soldering.

2tin96.5silver3copper0.5The melting point of solder is218℃Its properties are close to eutectic solder.

3tin42bismuth58The melting point of solder is138℃It is eutectic soldering.

4tin91zinc9The melting point of solder is199℃It is eutectic soldering.

5tin5zinc95The melting point is382℃It is eutectic soldering.

Based on the above, this is what I have explained to you about some of the functions and melting points of solder wire. I believe this way, you can understand it more clearly and conveniently.
