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.

    • Next, Viasion will talk about the hazards of halogens. First of all, one of the reasons why halogen is so widely used is that adding halogen into the material can improve the ignition point very well. In this way, the halogen will burn ahead of time, thus consuming oxygen, which is relative to enhancing the flame retardant coefficient.
    • However, when burning, halogen gas will be carried in the combustion gas, damaging the environment and affecting the health of organisms. In particular, the chlorine will produce many toxic gases during combustion, affecting organisms' oral and nasal cavities, including the lungs.
    • Not only for gases, but the halogen will also produce toxic substances soluble in water after combustion. It will evolve into toxic substances with substantial toxicity and transmissibility after synthesis, which will not only affect organisms but also cause corrosion to buildings, thus further improving the environmental requirements of halogen products in application. Otherwise, it will significantly affect the life and stability of products and cause damage.
    • The circuit boards made by Viasion, including many finished products in other electronic industries, will also use halogen products. It is not only the PCB work industry of Viasion. Halogens have been used as flame retardants in different industries. There are many kinds of flame retardants, of which PBB and PBDE are the most frequently used. Similarly, they will also produce harmful gases when burning, and will not volatilize directly. They will exist in the air for a long time and cause permanent damage.
    • According to the cooperation experience of Viasion, halides are widely found in printed circuit boards, such as halogen-containing materials in flame retardants of printed circuit boards. However, Viasion's experience shows PBB and PBDE are more toxic.
    • In Viasion's research, circuit boards and electronic products containing halogen will produce many by-products in the case of incomplete combustion, not only dioxin, but also furan-like compound, and acidic or corrosive gases, which have potential hazards to the environment and human health. Moreover, Viasion's production in telecommunications is not only PCB but also cable.
    • Viasion found that most PCBs contain halogen, which will emit toxic and harmful chemicals when burning. Not only in combustion, especially in fire, if the flame burns the shell of insulated wire, but the PVC insulation shell will also emit toxic gas during combustion, which will cause significant harm to the human body, especially for the oral cavity, nasal cavity and lung of organisms, and even cause irreversible damage. The black smoke will also affect people's vision, significantly reducing escape probability. For this reason, many of Viasion's cooperative customers, especially the European Union, strongly regulated the use of PBB and PBDE through the RoHS Act.
    • Due to the hazards of halogens mentioned above, more and more customers will limit the content of halogens or choose halogen-free PCB materials, and Viasion has also discovered this trend. When burning electronic devices, brominated materials will generate highly toxic dioxins. The halogen-containing materials required to be prohibited exceed RoHS's original restriction on PBB and PBDE.

    On the other hand, Viasion will discuss the presence of halogens in PCBs in normal production. 

    • The plastic PVC discussed above is used in everyday objects in our lives and various other processes. The PCB has many processes in the manufacturing process. For example, Viasion will use chlorinated solvents to clean the PCB. Including Viasion, when laminating PCBs, we will also choose BFRs to help production. As mentioned above, it can improve the flame retardancy coefficient, effectively reducing the fire risk. These processes, as Viasion said, exist in halogens.
    • The production and design of PCB halogen free must be more complex and need to be prepared at the beginning of design. According to Viasion’s many years of production experience, there is a big difference between halogen-containing and halogen-free flux. If you use a flux that does not contain halogen, sometimes it will affect the production quality, and if the ratio at the beginning of the design is not good enough, it will cause wrinkles. However, Viasion has rich experience in this area. We usually operate and optimize by using a solder mask to maximize the final product’s quality further and ensure that the product is free from defects.
    • According to Viasion above, it can be seen that halogen-free PCBs have strict tests for design and production technology and experience and require rigorous treatment and multiple confirmations during production. Although halogen-free PCBs materials are less popular than halogen-containing PCBs, Viasion has also spotted this trend. Therefore, Viasion believes that printed circuits made with halogen free material will become increasingly important with the development of society and the gradual enhancement of environmental protection awareness.
    • We need to pay attention in life. Halogens are usually used in flame retardants. Some insulating materials for wrapping wires are included in the circuit board so that we know how to selectively replace the material in the plate-making to achieve the ultimate environmental protection goal. It is critical for the fabrication and design purposes of a halogen-free PCB.

    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.

    2

    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.

    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.

    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.
