What is Halogen-Free PCB

 Halogen-free circuit boards use environmentally friendly materials that are harmless to human health and beneficial to the environment. Halogen-free PCBs also have the following benefits:

Environmentally friendly:When handling halogen-free printed circuit boards, they will not produce harmful substances such as halogen compounds, reducing environmental pollution and complying with the halogen ban of EU countries.
Protect the health and safety of workers:Halogen compounds are harmful substances that release toxic gases that are harmful to the human body at high temperatures.
Therefore, using halogen-free materials can reduce the harmful gases generated during the welding and heat treatment process, which not only protects the health and safety of workers but also improves the safety of the working environment.
Improve circuit board insulation:Halogen-free insulation materials are low-cost and effective for disposable electronic products. Since halogens are replaced by phosphorus or nitrogen, the polarity of epoxy resin is reduced, thereby improving the circuit insulate resistance and reducing the breakdown force of the current.
Lower water absorption:For boards, low water absorption affects improving the reliability and stability of materials. Phosphorus nitrogen molecules have fewer electrons than halogens. It is not easy to combine with water molecules, which means that halogen-free circuit boards have a higher resistance to water absorption. Although the scale of halogen-free printed circuit boards is much smaller than that of PCBs, they can better cope with humid environments and situations.
High thermal stability:The nitrogen and phosphorus content in halogen-free circuit boards is higher than that of ordinary boards, which increases the monomer molecular weight and Tg. Under heating conditions, the molecular mobility of halogen-free materials is lower than that of traditional epoxy resin boards. Therefore, halogen-free circuit boards have a lower thermal expansion coefficient, enabling them to withstand higher temperatures. Because halogen-free PCB can withstand high temperatures, it is more suitable for high-power product design.
Recyclable:Recycling halogen-free circuit boards can fully and effectively utilize the metal materials in circuit boards, such as gold, copper, silver, etc. Recycling these metal materials can reduce the demand for scarce resources, drive the growth of related companies, and provide more employment opportunities for social talents.
Improve market competitiveness:Nowadays, more and more consumers like environmentally friendly and safe electronic products, so halogen-free circuits can attract more consumers, thereby improving the market competitiveness of enterprises. Enterprises that use halogen-free materials can reflect their concern for the environment and incarnate their concern for the health of consumers and product quality, which is conducive to the long-term development of enterprises and can also improve brand reputation.
