What is Halogen Free PCB

To understand Halogen Free PCB, we need to know what is halogen first. Halogen are the elements such as fluorine (F), chlorine (CL), bromine (Br), iodine (I) and atastatium (At) which are fatal to life when exceeding a certain level. So Halogen Free PCBs are the printed circuit boards are produce by the material without or with very limited halogen elements. Normally we can classify it as halogen free if chlorine (CL), bromine (Br) are less than 900 ppm, and overall halogen elements are less than 1500 ppm.
When there is a fire, normal PCBs with halogen such as FR4, CEM1, CEM3 will produce lots of elements which are fatal to life, such as like dioxin, furan, and acid or corrosive gases. So halogen free PCBs are used widely used on the electronics such as automobiles and mobile phones, medical equipment, power stations, distribution rooms, laboratories and outdoor power systems.

    Detailed Introduction of Halogen Free PCB

    Halogen-free PCB is a very environmentally friendly PCB. It will not produce harmful substances and gases when burning like halogen PCB, which Viasion highly praises. Viasion has extensive experience in halogen-free PCB production. As the name implies, the material of them is made of a halogen-free substrate. Viasion has also been working hard on PCB halogen free for decades. Please call us any time for any of your halogen-free PCB fabrication demands. 

    Generally, according to Viasion’s production experience, PCB materials will contain specific concentrations of halogens, and environmentally friendly halogen-free PCB materials will replace these halogens with unique halogen-free materials to achieve the purpose of environmental protection.


    Next, Viasion will explain the environment-friendly type of Next, Viasion will explain the environment-friendly type of halogen-free PCB. It can not only protect the atmosphere of the earth but also protect the respiratory health of organisms. Therefore, it is an essential material. As Viasion mentioned above, the characteristic of printed circuits made by halogen-free material is the particularity of material making and proportioning and using materials with strong dehydration and flame retardancy to achieve the purpose of environmental protection. According to Viasion’s production experience and cooperation experience, it is mainly divided into two series. The first series is based on phosphorus.

    For Viasion, The main working principle of phosphorus is that it is contained in the resin PCB. When burned, it will form a carbonized protective film to prevent flames. The other is phosphorus nitrogen. Its principle is more straightforward than the previous one.

    The resin PCB containing it will not produce combustion gas directly when burned, which is equivalent to improving the flame retardancy coefficient. These two materials are currently the primary halogen-free printed circuit boards materials, including Viasion.  Please get in touch with us when you need any halogen-free PCB manufacturing service. 

    Halogen Free PCB’s Advantages and Features

    To put it simply, the advantage of halogen-free is that it is very environmentally friendly and has many features. Still, the relative disadvantage is that it is more challenging to produce and design.

    Someone may wonder, ” Regarding the nitrogen and phosphorus in the material of the halogen-free cicuits, if the fox pair electrons of N and P in his redox resin are much less than that of the ordinary halogen PCB, will that lead to a lower probability of hydrogen atoms forming hydrogen bonds in water?” The answer is yes.

    According to Viasion, that will further lower the material’s water absorption than the flame retardant coefficient of ordinary halogen PCB. Also, According to Viasion’s production experience, Viasion found that lower water absorption will further improve the stability of PCB materials, which is also a significant advantage and feature of halogen-free PCB material.

    According to Viasion’s production experience, the insulation is better than the ordinary halogen PCB. According to the experience of Viasion, it is believed that the particular material mainly comes from the halogen-free PCB, which makes the polarity of the molecular bond segment of the epoxy resin lower, thus achieving the effect of reducing the insulation. Viasion thinks this feature makes the PCB halogen free stronger in withstanding voltage.

    Halogen’s Definition and Hazard

    First of all, the definition of halogen. According to the production experience of Viasion, halogen composition is mainly F, CI, BR, I, and even at. But it is very harmful and is not included in the plate. It’s a hazardous, radioactive substance. So the main components are F, CI, BR and I. They also play a similar role in halogen-free PCBs. They are mainly used as flame retardants to improve the flame retardance of PCBs further to achieve the goal of environmental protection. In addition, Viasion will also use CFCS, HCFCS and other materials for freezing dose. Please contact our sales team to quote your halogen-free PCB manufacturing cost.

    Halogen Free PCBs and Environmental Protection

    Industrial revolutions bring environmental pollution

    Since the two industrial revolutions, steam and electronic technology development has changed with each passing day. At the same time as rapid development, it has also brought about severe environmental pollution. Over time, it has slowly caused devastating damage to species worldwide. Attack, when the growth rate of science and technology is gradually slowing down, the eyes of the world are also focusing progressively on environmental protection.

    Environmental protection is priority

    Environmental protection is closely related to life worldwide, and it is also a fundamental priority. Therefore, countries have begun to promote environmental protection policies, similar to the main content of this article is PCB halogen-free.

    Halogen-free PCB is highly praised

    Viasion thinks that the environmental protection features of halogen-free PCB make it highly praised by the electronics industry and worldwide. As Viasion said earlier, there is no doubt about production difficulty, but Viasion believes they must be higher and much more difficult. Because of the material, they will be more fragile, prone to breakage, and easy to produce white spots in some production stages. However, with the passage of time and development, Viasion believes that the status of PCB halogen free will be further and higher in the PCB industry.

    Halogen-free PCB materials will be more popular

    These are also some challenges. However, Viasion also believes that the application of halogen-free PCB materials will become increasingly popular because environmental protection is an issue that needs the close attention of all humanity. As environmental protection policies are paid more and more attention, Viasion will continue to improve and optimize the production process of printed circuit boards made of halogen free material.
