Halogen-Free PCB
Halogen-Free PCB
The popularity of halogen-free PCBs is increasing due to the demand for environmentally friendly electronic products. These PCBs are made of materials that are free of halogen. The dielectric constant, dissipation factor, and moisture diffusivity of halogen-free materials differ from those used in traditional printed circuit boards. If your product needs to be environmentally friendly, Halogen-free PCBs are the ideal choice.

Bebefits of Halogen-Free PCB
What are the benefits of using halogen-free PCBs?
First, it’s essential to understand that halogen is not a material. It is a way to describe a class of elemental gases, including fluorine, chlorine, bromine, iodine, and astatine. While PCBs containing halogen gases are generally safe, these elements are toxic. They can cause reactions from blurred vision and nausea to difficulty breathing and a burning sensation in the eyes, nose, and throat.
When a PCB is eventually disposed of, the disposal process can potentially release these elements into the environment, polluting the atmosphere. The incineration of halogen-based components can produce dioxin, which the EPA defines as one of the most toxic chemicals known to man. The EPA has confirmed inhaling dioxin, even in small doses, will almost invariably lead to cancer and ultimately death.
The significant benefit of halogen-free boards is that they do not pose the same threat to the environment, which can be great for environmentally-conscious companies and environmentally-conscious consumers who patronize those companies.
Applications of Halogen-Free PCB
What types of industries and applications are halogen-free PCBs typically used in? Halogen-free PCBs can be used in any industry or application where you would use electronic PCB boards, from consumer electronics to industrial automation and everything in between. While there is some variance in the specifications of halogen-free PCBs compared to PCBs which contain chemicals like chlorine and bromine, these boards are entirely practical and suitable for most applications.
If you’re concerned about how halogen-free boards will work with your specific application but would still like to try them, feel free to call us to discuss the issue. Our PCB experts will be more than happy to talk to you about the differences between halogen-free PCBs and other printed circuit boards and how those differences may or may not affect your specific product.
Although all companies can use halogen-free PCBs, they appear most often in companies committed to being better to the environment, reducing their carbon footprint, and being responsible for the toxins they emit into the atmosphere due to their production processes.
