The importance of using lead-free soldering iron tips
Release Date：2018-03-29
The characteristics of lead and its harm to the human body: lead (Pb), a gray white metal with a melting point of 327.5 ℃, releases a large amount of lead vapor when heated to 400-500 ℃,
And it rapidly oxidizes into lead oxide in the air, aggregates into smoke and dust, and dissipates everywhere.
The industries that come into contact with lead in industry mainly include lead mining, lead burning ropes and refining, battery manufacturing, welding of electronic products, and lead spraying of electronic components.
In the above contact, lead and its compounds mainly invade the human body through respiratory production and digestive tract, causing lead poisoning and posing a threat to human health. A study by the US Environmental Protection Agency found that,
Lead and its compounds are one of the 17 chemical substances that seriously endanger human lifespan and the natural environment. The usual occupational lead poisoning is chronic poisoning, which affects the nervous system of the human body
Both the digestive and blood systems can cause interference and damage, with symptoms including dizziness, headache, fatigue, decreased memory, nausea, irritability, loss of appetite, abdominal distension and pain
Anemia, mental disorders, etc.
So whether from the perspective of people's increasing concern about health or environmental protection, lead-free soldering replacing lead will become an inevitable trend.
