Information

The placement machine plays a vital role in our lives. We often use mobile phones, or computers and other electronic products. Their main operating space is the motherboard, and the placement machine is an intelligent machine responsible for rapid placement. Equipment, in the placement machine, we often need to solder to complete the solid role of component placement, so what are the common soldering processes? We together look.

1. Contact welding: During the welding process, pressure (heating or not heating) must be applied to the weldment to complete the welding.

2. Fusion welding: fusion welding refers to the method of heating the weldment joint to a molten state during the welding process of the placement machine, and completing the welding without applying pressure.

3. Brazing: Brazing uses a metal material with a lower melting point than the part to be welded as the solder. The part and the solder are heated to a temperature higher than the melting point of the solder and lower than the melting point of the solder, and the welded material is wetted by the liquid solder. Object, and mutually diffuse with the object to be welded to achieve connection.

Brazing can be divided into brazing and soft brazing according to the melting point of the used solder. The soldering with the melting point of the solder higher than 4500C is called brazing; the soldering with the melting point of the solder lower than 4500C is called the soldering. When we are mounting electronic products, the soldering mentioned is actually a kind of soft soldering, mainly using low melting point alloy materials such as tin and lead as solder, so it is commonly called "tin soldering".

We seem to be relatively simple when we are soldering. In fact, it is the process of combining molten solder and the metal to be welded (base metal), but the microscopic mechanism is very complicated. It involves physics, chemistry, materials science, electricity, etc. Knowledge. Familiar with the basic theory of welding, we can achieve better results in the welding work of our placement machine.
