Today, with the rapid development of modern electronic technology, PCB boards (printed circuit boards) and integrated circuits are ubiquitous. From mobile phones, computers to various smart devices, they are all key components of these devices. However, with the increasingly frequent upgrading of electronic products, a large number of PCB boards and integrated circuits are discarded. How to effectively recycle them has become an important issue. PCB boards and integrated circuits contain a variety of precious metals and materials, such as copper, gold, silver, and tin. If these resources can be recycled properly, it can not only reduce the pressure on the exploitation of natural resources, but also reduce environmental pollution. Through professional recycling processing techniques, these metals can be extracted from discarded circuit boards, refined, and then reused, achieving the goal of resource recycling. At the same time, during the recycling process, attention should also be paid to environmental protection. Use environmentally friendly chemical agents and processing methods to avoid causing pollution to soil and water. And ensure the safety of the recycling process and protect the health of workers. The recycling of PCB boards and integrated circuits is a work of great significance. It concerns both the sustainable use of resources and environmental protection. We should attach great importance to and actively promote this work, so that the development of electronic technology and the protection of the ecological environment can complement each other.
