With the growing awareness of environmental protection, the electronics manufacturing industry is also paying more attention to the environmental protection of its processing and manufacturing processes in order to seek sustainable development, PCB assembly manufacturers are also constantly looking for and adopting environmentally friendly technologies to reduce pollution of the environment. The following points need to be focused on:
Hi-Top Electronic Technology
Use of environmentally friendly materials
PCB assembly manufacturing process uses a variety of materials, some of which are harmful to the environment. Therefore, PCB assembly manufacturers should try to use environmentally friendly materials, such as lead-free solder and water-based paint.
Adoption of environmentally friendly processes
The processes used in the PCB assembly manufacturing process may also pollute the environment. Therefore, PCB processing and manufacturing companies should adopt environmentally friendly processes, such as lead-free soldering processes, water-based coating processes, etc.
Strengthen the waste treatment
PCB processing and manufacturing process will produce a large amount of waste, such as waste water, waste gas, waste residue, etc.. These wastes, if not treated, will pollute the environment. Therefore, PCB assembly manufacturers should strengthen the waste treatment, such as waste water treatment, waste gas treatment, waste residue treatment, etc..
The following are some common environmental protection technologies in PCB assembly manufacturing:
Lead-free soldering process
Lead-free soldering process refers to the use of lead-free solder instead of lead solder in PCB processing and manufacturing. Lead-free solder is much less polluting to the environment than lead solder.
Water-based coating process
Water-based coating process refers to the use of water-based paint in the PCB processing and manufacturing process. Water-based paints are much less polluting to the environment than solvent-based paints.
Wastewater treatment technology
Wastewater treatment technology refers to the PCB processing and manufacturing process of wastewater treatment, so that it meets the discharge standards. Wastewater treatment technology includes physical treatment, chemical treatment and biological treatment.
Exhaust gas treatment technology
Exhaust gas treatment technology refers to the PCB processing and manufacturing process of waste gas treatment, so that it meets the emission standards. Waste gas treatment technology includes absorption method, adsorption method, catalytic combustion method and so on.
Waste residue treatment technology
Waste residue treatment technology refers to the PCB processing and manufacturing process of waste residue treatment, so that it reaches harmless, reduction and resourcefulness. Waste residue treatment technology includes incineration method, landfill method, composting method and so on.
By adopting the above environmental protection technologies, PCB assembly manufacturers can effectively reduce pollution to the environment and achieve environmentally friendly production.
