Introduction to PCB circuit boards
Also known as printed circuit boards, they are providers of electrical connections for electronic components and are substrates for assembling electronic components.
The design of circuit boards is mainly layout design. The main advantage of using circuit boards is that they greatly reduce wiring and assembly errors, and improve the level of automation and production labor rate.
According to the number of layers of the circuit board, it can be divided into single-sided, double-sided, four-layer, six-layer and other multi-layer circuit boards.
Development of the PCB industry
It belongs to the basic industry of the electronic information product manufacturing industry.
By seizing the opportunity of a new round of development in the global electronic information industry, promoting independent innovation, and achieving stable and sustainable development of China's printed circuit industry.
Through independent innovation, a complete set of high-end materials, equipment, instruments and service industries is formed.
Recycling of waste circuit boards
With the rapid development of science and technology, the number of discarded electronic and electrical products has increased. Circuit boards are the main component of electronic and electrical products, and are also the difficulty of recycling discarded electronic and electrical products.
Foreign circuit board recycling pays more attention to the reuse of electronic components, extending the service life of electronic components as much as possible, so as to reduce the demand for new materials and waste emissions in the production process, and achieve resource and energy conservation.
Circuit board disassembly equipment
Circuit board disassembly equipment (board burning machine) is used to process old home appliance circuit boards, circuit boards and defective products containing various electronic components (such as capacitors, relays, transformers, etc.).
The equipment separates the electronic components and solder on the waste circuit boards from the circuit boards by thermal detinning.
The disassembled circuit boards enter the crusher for crushing, and the recovered tin is sold as a product; the waste gas generated is mainly dust and waste methane.
