The basics of lead-free low-temperature solder wire
Introducing the basics of lead-free low-temperature solder wire soldering work.
Soldering operations can be divided into the following.
The coupling of mechanical equipment, the coupling of 2 metal materials, fixed and immobile efficacy. Electrical equipment coupling, the coupling of two metal materials, so that the effectiveness of electrical equipment through and through. This type of electrical equipment connection is a characteristic of welding work, and is not possible with adhesives.
Characteristics of welding work. Soldering is characterized by the ability to perform a large number of simultaneous soldering operations, such as soldering with a jet bath and soldering with adhesive solder, and by the ease of adjustment.
The concept of solder. In general, solder is an aluminum alloy composed of both tin and lead. Some of the solder made up of tin and lead content can be eutectic solder, and the melting point of this type of solder is low.
The setting temperature of the soldering operation. When soldering operation, the temperature setting is a more critical part, the setting temperature of the soldering iron head, because the size of the soldering part, the output power and characteristics of the electric chromium iron, the type and linearity of the solder is not the same, there are differences in the temperature.
As lead is harmful to the environment, the composition of the solder needs to be rectified, so the use of more lead-free solder material of the wire, such as lead-free low-temperature wire.
