The alloy composition of leaded solder paste and lead-free solder paste is different

The alloy composition of leaded solder paste and lead-free solder paste is different

Jan 04, 2023

01-042023

The components of lead-free solder paste are: Sn, Ag, Cu, Bi, and the main components of leaded solder paste are: Sn, PB. We cannot directly distinguish this alloy with the naked eye. It needs to be detected by a spectral analysis instrument. detection.

1. It is said that it is due to the solvent in the formula of the flux in the lead-free solder paste. It is true. If the flux used to produce solder paste is volatile
Of course, the solder paste will dry out slowly during use. However, there are too many factors for the dryness of solder paste, and the dryness of solder paste is due to the instability of the flux system.

Rosin is a common additive in lead-free solder bars, so rosin will not cause electrical conductivity. It is an insulator itself, but the additive content of lead-free solder bars contains rosin but there are other active substances. Lead-free solder bars Excessive metering of some active substances may cause leakage.

Lead-free tin bar solder is more or less toxic, and tin bar solder is divided into lead-free solder and leaded solder. Is lead-free solder toxic? The gas produced when using lead solder wire is toxic Yes, in addition to gases such as rosin oil and zinc chloride, lead vapor will also be produced. But now the tin wire is lead-free. Do not inhale the fumes generated during soldering of lead-free tin bars. Generally, factories will install fume exhaust pipes to reduce harm to the human body. Do a good job of ventilation.

The solid core needs the assistance of flux during welding, because there is no flux in this type of solder wire, hence the name solid core solder wire. The flux used for soldering with solid solder wire is preferably a combination of rosin and a small amount of activator, similar to the type of flux in ordinary solder wire.
