What is the concept and content of cleaner production in PCB board production?

The materials used in the production of circuit board processing contain many harmful substances, and many harmful substances will be produced in the production process, especially the "three wastes" produced, which will cause great harm to the environment. If left to itself, it will not only have a serious impact on the sustainable development of society and economy, but also cause great harm to the human body. Therefore, for the printed board production industry, from the beginning of product design to the entire manufacturing and use of the whole process must be strictly controlled materials, improve the production process, the use of advanced pollution-free or low-pollution technology, as well as the printed board electroplating and chemical production process into the "three wastes" for strict monitoring and scientific management. Strengthen the clean production management of printed board, which is related to the survival of the circuit board processing plant production enterprises.

Clean production includes two aspects of clean production process and clean production products. In the concept of cleaner production, it includes not only technical feasibility, but also economic profitability. It should fully reflect the unity of economic benefits, environmental benefits and social benefits.

1. Cleaner production refers to the continuous application of environmental strategies of comprehensive prevention in production processes and products to reduce the harm to humans and the living environment. For the production process, cleaner production includes saving raw materials and energy, eliminating toxic raw materials, and reducing the quantity and toxicity of all emissions and wastes before they leave the production process; For products, cleaner production strategies mean reducing the impact of a product on the human environment throughout its life cycle, from the processing of raw materials to the final disposal of the product. Cleaner production is achieved by applying specialized technology, improving process and changing management. The purpose of cleaner production is to realize rational utilization 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 the generation and emission of pollutants and waste, promote the compatibility of printed board industrial production and product consumption process with the environment, and reduce the harm to human beings and the living environment throughout the production cycle.
2. Clean production to "energy saving and consumption reduction, comprehensive utilization, pollution reduction and efficiency" as the goal; Strengthen training, improve the ideological awareness and technical quality of employees in cleaner production, strengthen production management, rely on technological progress, adopt reasonable and practical process technology and other measures; In line with the principle of treating pollution first, try not to use or use less harmful substances, so that the production of pollutants in the production process, emissions to achieve the minimum and harmless, and the waste in the production process to achieve resources.
