Nowadays, the electronics industry is growing larger and larger, and accordingly, the demand for employees is also increasing. When working in these factories, people are bound to encounter some problems, such as inconsistent positions. For instance, in the electronics industry, solder wire is an indispensable medium connecting components and circuit boards, and it is widely used in the production and maintenance of the electronics industry. During the welding process at work, a lot of smoke will be produced. So, is this smoke harmful to the human body? How to deal with this problem? JJY solder Paste Manufacturer would like to popularize some knowledge for everyone:

Although the main component of solder wire is tin, it also contains other metals. It is mainly divided into leaded and lead-free types (i.e., environmentally friendly types). With the European UnionROHSThe introduction of standards has led to an increasing number of factories choosing lead-free and environmentally friendly types. Leaded solder wires are also gradually being replaced, and those that are not environmentally friendly cannot be uttered. Lead-free solder paste, lead-free solder wire and lead-free solder bar are the main products on the current market:

Lead-containing ones are mainly composed of tin and lead in various proportions; Environmentally friendly, composed of tin-copper, tin-silver-copper, etc

1Leaded solder: Composed of tin (melting point232Degree) and lead (melting point327An alloy composed of degrees. Among them, tin63%And lead37%The composed solder is called eutectic solder, and its melting point is183Degree.

2Lead-free soldering: Proposed to meet the environmental protection requirements of the European UnionROHSStandard. Solder is made of alloys such as tin-copper and tin-silver-copper.

Like leaded solder wire, because it contains lead, the toxicity of lead is known to all. The soldering of circuit boards is relatively safe. It is a rather delicate and demanding type of soldering. The smoke produced during the soldering process is all caused by the flux contained in the tin wire. The flux is composed of rosin and some active agents and has a certain smell, but this is not very harmful. As long as a mask or gas mask is worn during soldering, the exhaust system in the workplace is good, and hands are washed after work, these are all good preventive measures.

As for some people's question about whether lead, a metal, will evaporate along with the smoke during the welding process and be inhaled inadvertently, this is generally not the case, as the temperature is not high enough. However, it is still recommended that during the work process, as many preventive measures as possible be taken and one should not seek convenience.

Lead-free solder wireThe odors and smoke produced during the welding process are all caused by flux and rosin, which are not very toxic. Just pay attention to the exhaust. Welcome to choose the lead-free solder of Yidiantong brand. It is odorless and produces less smoke.

Note when using lead-free solder wire:

1Keep the working environment well-ventilated.

2Smoke less and drink more water. This can help eliminate most of the harmful substances absorbed.

3Wash your hands frequently. After completing the welding work, wash your hands before meals and before drinking water.

4Wear a mask when working.

As mentioned above, this is what the editor has explained to you about some common sense. I think everyone should have understood whether lead-free solder wire is toxic or not. During the work process, do some preventive awareness, which is also good for your own health.
