Halogen-Free PCB
Halogen-Free PCBs: A Brief Introduction
Halogen-free printed circuit boards are becoming increasingly popular due to the growing demand for environmentally friendly electronics. They are made from materials that do not contain halogen. Halogen-free materials differ from traditional printed circuit board materials in terms of dielectric constant, moisture diffusivity and dissipation factors. Hence, if the product you're engaged in requires to be environmental-friendly, Halogen-free PCBs will be your ideal choices.

Halogen-free PCB Benefits
What are the advantages of using PCBs that do not contain halogen? It's important to first understand that halogen itself is not a substance. This is the term used to describe elemental gases such as fluorine. chlorine, bromine and astatine. Although PCBs that contain halogen gas are generally safe, they can cause reactions ranging from nausea and blurred vision to breathing difficulties and burning in the nose, eyes and throat.
The disposal of a PCB can release these elements in the air, polluting it. In fact, incineration can create dioxin which is one of the world's most toxic chemicals. The EPA confirmed that inhaling even small amounts of dioxin will almost always lead to cancer, and eventually 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.
Halogen-free PCB Applications
Halogen-free PCBs are used in what types of industries or applications? Halogen-free printed circuit boards can be used anywhere you'd use printed circuits, from consumer electronics and industrial automation to everything in between. These boards are effective for many applications, even though they differ slightly from PCBs that contain chemicals such as chlorine or bromine.
Call us to discuss your concerns. If you are unsure about the compatibility of halogen-free circuit boards with your application, but still want to test them out, we'd be happy to help. Our PCB experts are happy to discuss the differences between halogen free PCBs and printed circuit boards as well as whether or not they may affect your product.
While all companies are able to use halogen-free pcbs, the majority of them appear in those that have made a commitment to be better for the environment, reduce their carbon footprint, and take responsibility about the toxins released into the air as a result their production process.
