Brief Introduction on Halogen-free PCB

With the increasing demand for environmentally friendly electronic products, halogen-free PCBs are becoming more and more popular because they are constructed of materials that are free of halogen. The dielectric constant, dissipation factor and moisture diffusivity of materials that are described as halogen-free are different from those employed in traditional printed circuit boards. Hence, if the product you're engaged in requires to be environmental-friendly, Halogen-free PCBs will be your ideal choices.
