The materials used by PCB smt assembly company in the production of electronic smt assembly contain many harmful substances, and many harmful substances will also be produced during the smt assembly process, especially the "three wastes" generated, which will cause great harm to the environment. , not only has a serious impact on the sustainable development of society and economy, but also causes great harm to the human body. Therefore, for the printed board production industry, the whole process of smt assembly from product design to the entire manufacturing and use must strictly control materials, improve production processes, adopt advanced non-polluting or low-polluting technologies, smt assembly plants and Strict monitoring and scientific management of the "three wastes" produced in the process of printed board electroplating and chemical production, and strengthening of printed board clean production management are related to the survival of the smt assembly plant.

In the concept of smt assembly green production, it includes not only technical feasibility, but also economic profitability. It should fully reflect the unity of economic, environmental and social benefits.

1. Green production refers to the continuous application of comprehensive preventive environmental strategies to production processes and products to reduce harm to humans and the living environment. For the production process, green production includes saving raw materials and energy, eliminating toxic raw materials, and reducing the quantity and toxicity of all emissions and wastes before leaving the production process; for products, green production strategies refer to reducing product The impact on the human environment during the entire life cycle, from the processing of raw materials to the final disposal of the product. Green production is achieved by applying specialized technologies, improving processes and changing management. The purpose to be achieved is to realize the rational use of resources and slow down the depletion of resources through comprehensive utilization of resources, substitution of scarce resources, utilization of secondary energy, energy saving, water saving and material saving; in the production process, reduce or eliminate pollutants. And the generation and discharge of waste, promote the compatibility of the PCB board industrial production and product consumption process with the environment, and reduce the harm to humans and the living environment throughout the production cycle.

2. The goal of smt assembly green production is "energy saving, consumption reduction, comprehensive utilization, pollution reduction and efficiency improvement"; strengthen training to improve employees' ideological awareness and technical quality of green production, strengthen production management, rely on technological progress, adopt Reasonable and practical process technology and other measures; in line with the principle of pollution control first and root cause, try not to use or use harmful substances as little as possible, so as to minimize and harmless the generation and discharge of pollutants in the production process, and waste in the production process. Be resourceful.
