The difference between lead-free soldering station and leaded soldering station:

Lead Free Soldering Station

Lead-free soldering stations are used in a wide range of applications, from common electronic appliance repairs to electronic integrated circuits and chips. Lead-free soldering stations are used as soldering tools, but are most commonly used for soldering of PCB circuit boards in electronic production factories. It is especially suitable for soldering operations of lead-free precision electronics.

After the electronic products are scrapped, the lead in the solder of the PCB board is easily soluble in oxygen-containing water. Pollute water sources and damage the environment. The solubility makes it accumulate in the human body, damage the nerves, cause sluggishness, hypertension, anemia, reproductive dysfunction and other diseases; if the concentration is too large, it may cause cancer. Cherish life, the times require lead-free products. As an important part of PCB circuit board manufacturing, soldering must be lead-free, so the lead-free soldering station was born.

Difference from lead soldering station

In fact, the main difference is the soldering temperature. The welding temperature required for lead-free tin wire is higher, generally around 250 degrees, while the welding temperature of ordinary tin wire is 180 degrees, so the welding temperature of lead-free soldering station is higher. And the lead-free soldering station heats up faster. Of course, there are exceptions. Among lead-free solders, there are also low-temperature solders that have a lower melting point than leaded solders. But this low temperature solder is quite expensive.

In theory, lead-free soldering stations can also be used with lead solder joints, because the temperature of lead-free soldering stations can reach the melting point of leaded solder. But no one actually uses it this way, because once lead-free solder is used for soldering on a lead-free soldering station, the lead-free soldering station is polluted and can no longer be used as a lead-free environmentally friendly product.

Conversely, lead-free solder cannot be soldered with a leaded soldering station, because the temperature of the leaded soldering station may not reach the melting temperature of lead-free solder.
