<span>Brief Introduction on Halogen-free PCB</span>
</p>
<p class="MsoNormal">
<span>&nbsp;</span>
</p>
<p class="MsoNormal">
<span>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.</span>
