Halogen-free circuit board, set off a new trend of environmental protection

Halogen-free circuit board are circuit board that do not contain toxic or hazardous substances in the manufacturing process and do not pollute the environment. This type of circuit board has higher safety and reliability in the process of use, and also meets the current social requirements of green environmental protection and sustainable development.

Halogen-free circuit board do not use halogens in the manufacturing process and therefore do not produce halogen compounds. Halogen compounds are powerful flame retardants, but they are very harmful to the environment and human health. Conventional circuit board use bromides or other halogenated compounds as flame retardants during the manufacturing process, and not only are these compounds harmful to the environment, but they may also release hazardous substances during use that can affect people’s health.

In contrast, halogen-free circuit board adopt a more environmentally friendly manufacturing method, using environmentally friendly flame retardants such as inorganic or phosphorus-based compounds instead of halogen compounds. These flame retardants not only have better flame retardant properties, but also do not release harmful substances during use, which has less impact on the environment and human health.

In addition to being more environmentally friendly, halogen-free circuit board have higher reliability. Since halogen-free circuit board do not contain toxic or hazardous substances during the manufacturing process, the presence of hazardous substances will not affect the performance and reliability of the board. At the same time, halogen-free circuit board do not cause secondary pollution of electronic products due to the release of hazardous substances, thus ensuring product safety and reliability.

Halogen-free circuit board are a more environmentally friendly, safe and reliable circuit board, its appearance in line with the current social requirements of environmental protection and sustainable development. With the increasing awareness of environmental protection, I believe that halogen-free circuit board will be used in more areas.

Halogen-free circuit board production matters needing attention

Halogen-free circuit board are circuit board that do not contain halogen elements. Halogen is a halogenated hydrocarbon, including fluorine, chlorine, bromine, iodine and other elements. Since halogens are highly reactive and release toxic gases at high temperatures, materials containing halogen elements need to be avoided in the manufacturing of certain electronic products. The following will introduce the matters that need to be paid attention to during the production process of halogen-free circuit board.

1. Selection of raw materials

First of all, the raw materials for halogen-free circuit board should be halogen-free. For copper-clad boards, halogen-free copper foils and halogen-free substrates can be used. Halogen-free copper foil refers to the copper foil that does not use halogen elements in the manufacturing process, while halogen-free substrate refers to the substrate of insulating materials such as phenolic resin or epoxy resin that does not contain halogen elements.

2. Production process

In the production of halogen-free circuit board, attention needs to be paid to the production process. First, the substrate needs to be processed and drilled. When drilling holes, attention needs to be paid to the accuracy of the hole diameter and hole depth to avoid any impact on subsequent processing. Second, the calendering and lamination of copper foil is required. The thickness and surface treatment of the copper foil will affect the electrical performance and service life of the circuit board. Finally, the circuit board needs to be pressed and molded. In this process, temperature and pressure need to be controlled to ensure the flatness and precision of the circuit board.

3. Quality control

In order to ensure the quality of halogen-free circuit board, strict quality control is needed. First, raw materials need to be inspected to ensure that the raw materials meet the requirements. Secondly, in the production process needs to be inspected and sampling, in order to find problems in the production process and solve them in a timely manner. Finally, the need to test the finished product to ensure that the appearance of the board, size, electrical performance and other requirements.

In short, the production of halogen-free circuit board need to pay attention to the selection of raw materials, production processes and quality control and other aspects of the matter. These measures can ensure the quality and service life of the circuit board, but also reduce the impact on the environment.
