Is solder paste toxic? What protective measures are needed? JJY Solder Paste Factory would like to share with you:

There are two types of solder paste available today. One isLead-free soldering. Whether it is leaded solder or lead-free solder, both are toxic.
The alloy of tin and lead is the solder commonly used for passing through canals. It has the good electrical conductivity of metals and a low melting point, so For a long time, it has been used in welding processes. Its toxicity mainly comes from lead. The lead fumes produced by soldering can easily lead to lead poisoning. Lead is a heavy metal element that is harmful to the nervous system. Metallic lead may produce lead compounds, all of which are classified as hazardous substances. In the human body, lead can affect the central nervous system and kidneys. The environmental toxicity of lead to some organisms has been widely confirmed. The blood lead concentration reaches10μg/dlThe above will produce sensitive biochemical effects. If exposed for a long time, the lead concentration in the blood will exceed60~70μg/dlIt will cause clinical lead poisoning.

After clarifying the toxicity of lead to the human body, people began to look for new solder, which led to the later lead-free solder. Lead-free solder is mainly an alloy of tin, silver and other metal components. Silver, as a standard element of lead-free alloys, is more toxic to the ecology than lead in some aspects..In addition, other metals in lead-free solder alloys also show varying degrees of toxicity. Now, let's have the editor tell you what precautions need to be taken?

Take preventive measures: for instance, wear gloves, masks or gas masks, ensure good ventilation in the workplace with a good exhaust system, clean up after work, and drinking milk can also prevent lead toxicity in soldering.


1.It's necessary to take a break for a while. Generally, it's repaired1Take a break during the hours.15About a minute, because the resistance is the weakest when one is tired.

2.Smoke less and drink more water. In this way, most of the absorbed harmful substances can be excluded during the day.

3.Drinking mung bean soup or honey water before going to bed can reduce internal heat. Moreover, mung beans and honey can eliminate a large amount of lead and radiation absorbed!

4.Avoid radiation as much as possible and use mobile phones less.

5.You can make the soldering iron brighter and use it as much as possiblePPDThe welding head is such that when the temperature is reached, less welding oil and rosin can be used, reducing the harm to the body.

6.When the soldering oil starts to smoke, try to tilt your head a little to the side and hold your breath as much as possible.

7.Use more alcohol. , Brushing with alcohol for a longer time will have a similar effect.

8.Wash your hands clean and wash them frequently.

9.Ensure adequate sleep. As long as you sleep well, most impurities can be excreted through your body. 

10.Work with a mask on.
