The specialty is engaged in the electronic product SMT processing welding operator contact every day is printed circuit board, solder and flux related materials, tools, and other work. Therefore, in addition to paying attention to the above electricity safety, operators also need to master the knowledge of this aspect, in order to ensure their safety and health.
The hazards of lead in solder and rosin in flux and the knowledge of circuit board manufacturers that flux may contain other types of chemicals and solvents. In the automatic welding process, the printed circuit board is coated with a layer of flux on the surface, and then immersed in the solder tank for welding, which will also produce a large amount of flux smoke. The flux manufacturer shall, for the sake of the safety of the operators, conduct adequate site environment layout and testing before it can be used in welding operations.
SMT placement plant
How to reduce the harm that harmful material causes to human body? Electronics manufacturers need to layout their operations like this:
In the position of welding operation and circuit board printing workshop, metal melting area of solder raw material, smoke generated by welding, welding operation position, ventilation pipe shall be installed on the passageway in the workshop, and local exhaust device shall be provided.
According to the research report, some female workers were poisoned and inflamed by the smoke of solder. Although the sensitivity and response of each operator to the irritating components vary greatly, the smoke from the solder is also one of the causes that should not be ignored. Lead poisoning should be paid attention to at welding operation site. Care should be taken not to stain clothes and fingers when operating with rosin solder. In terms of hygiene management, consider wearing safety gloves, washing hands after work, changing work clothes, etc. Local ventilation equipment or overall ventilation design should be installed in the workshop.
