Welding machines will produce smoke and dust when welding, and some people want to ask where the smoke and dust come from. When spot welding, due to the high temperature, the metal evaporates and fumes are generated during welding. The fumes are condensed into fumes through the air. So, how do we reduce the formation of smoke and dust when we work? Welding fumes harm the human body. The hazard of welding fumes to the human body is the accumulation of soot particles in the lungs of the human body. However, if there is a correct welding posture and a good working environment (good ventilation), the harm to the human body will not be too great, and an occupational disease will be formed for a long time! Must be equipped with mobile welding fume purifier, welding dust removal equipment!

The production technology is to print on the pads corresponding to the substrate, use the placement machine to paste the parts on the pads, and use the reflow soldering technology to solder the substrate and the parts.

In the entire production process, there are two links that are prone to pollution. The first link is in the process of printing and patching, direct contact with cream or smearing will cause pollution. The second link is that during the reflow soldering process, the substrate coated with the attached parts enters the reflow soldering furnace. The soldering production is melted and cooled by the reflow soldering. There are chemical agents that damage the body, and the reflow soldering will cause pollution. The main ingredients in the cream are cream and flux, which affect the overall performance of the cream. The difference is the alloy composition. The metal composition includes 2-3 types of metals such as lead, silver, copper, and bismuth. Among them, lead is harmful to the human body, so reflow Improper soldering operation, reflow soldering will cause environmental pollution. Therefore, reflow soldering requires a polluted air recovery system, and the exhaust and ventilation of reflow soldering must be completed, and the Reflow soldering fume filter is installed to reduce exhaust gas pollution.
