Against the backdrop of increasing global environmental awareness, the PCB industry is facing unprecedented environmental pressure, and green transformation has become an inevitable choice for the industry's sustainable development. The PCB production process involves the use of a large amount of chemical substances and the discharge of wastewater, exhaust gas, and waste residue. If not handled properly, it will cause serious pollution to the environment. Therefore, how to achieve green production while ensuring production efficiency and product quality has become an urgent problem to be solved in the PCB industry.

Firstly, starting from the raw material stage, many PCB companies have begun actively seeking environmentally friendly raw materials to replace traditional materials. In the traditional production process of copper-clad laminates, materials containing harmful substances such as brominated flame retardants are often used, which may pose a threat to the environment and human health after combustion or disposal. Nowadays, some companies have developed environmentally friendly raw materials such as halogen-free copper-clad laminates, which not only meet environmental requirements, but also have performance that is not inferior to traditional materials. In terms of raw materials such as ink and electroplating solutions, they are also developing towards low toxicity and low pollution. Some companies use water-based ink instead of oil-based ink, greatly reducing the emission of volatile organic compounds (VOCs) and reducing pollution to the atmospheric environment.

In terms of production technology, enterprises achieve energy conservation and emission reduction through technological innovation. In the etching process, traditional etching methods generate a large amount of etching waste liquid, which is difficult to treat and costly. Nowadays, some advanced PCB companies have adopted micro etching technology, which reduces the use of etching solution and the generation of waste liquid by precisely controllin
