During this period of time, people often joked that he was therePCBAThe processing factory has been doing soldering with a soldering iron for one or two years. I haven't been feeling well recently. My abdomen is a little swollen. Is it because he was frequently exposed to welding wire and poisoned? Is the welding wire toxic? Today, the solder paste manufacturer will take you to see if the solder wire is toxic and if it is harmful to the body.

Is solder wire harmful to the body?

Whether solder wire poses radiation hazards to our bodies mainly depends on whether leaded or lead-free solder wire is used in the work. Among the components of solder wire, only lead causes relatively greater harm to our bodies, while tin itself has no impact on our bodies.

Tin has been used by people since ancient China. In daily life, ancient Chinese people would cast tin into containers, such as tin kettles and tin cans, to hold wine and tea, which could effectively extend the shelf life of wine and tea. Up to now, with the development of intelligent technology, people have made tin foil and tin foil and used them for baking, roasting, steaming and other purposes of food. Eating food wrapped in tin foil will not have a certain impact on our bodies, so there is no need to worry.

After talking about tin, let's now discuss "lead". Compared to tin, lead is obviously much more harmful to our bodies. Lead is a toxic and harmful substance. Frequent and excessive exposure can cause harm to our bodies. Excessive absorption by the human body can lead to lead poisoning. Moreover, the lead content in solder wire is generally not low. Besides, lead in daily environments is not easy to release and has a high boiling point1740℃As long as everyone strengthens daily prevention, the harm caused to our bodies can also be regulated. If possible, we can also consider lead-free solder wire.

Why is lead-free solder wire recommended?

Lead-free solder wire, also known as environmentally friendly solder wire, is designed to better comply with the regulations set by the European UnionRoHSIt emerged with the introduction of standards. European UnionRoHSThe standard is a mandatory standard formulated by EU legislation, which restricts the inclusion of lead and other substances in electronic products6The content of a substance. In order to meet the standards, the lead content of lead-free solder wire is very low. Therefore, lead-free solder wire poses little harm to our health and can be purchased and used with confidence.

Is the smoke from the process of soldering wire harmful to the human body?

The smoke that everyone can see during the soldering wire process is produced by the release of rosin from the soldering wire. Rosin is the most common oil resin in the Pinaceae family and does not pose a significant radiation hazard to our bodies. There is no need to worry too much. Moreover, the necessary preventive measures must still be taken. After all, the responsibility is to frequently touch upon it. Even if the radiation hazard is small, it will still cause mutations constantly.

OperationSolder wireHow is prevention generally carried out?

1Firstly, if the process and conditions permit, lead-free and environmentally friendly tin wire should be chosen as much as possible to minimize the noise hazard to the greatest extent.

2When spot welding, wear personal protective equipment such as gloves, goggles, protective face shields or protective face shields.

3The workplace should be well-ventilated indoors, with Windows open or a ventilation system.

4After a period of welding work, it is essential to pay attention to going out for ventilation and getting some fresh air.

5It is necessary to pay attention to personal care. Frequent hand washing can remove the lead adhering to your hands.
