• Halogen-free CCL. It refers to CCLs whose content of chlorine (Cl) and bromine (Br) is controlled within 900ppm while their overall content is no more than 1500ppm. Performance comparison between halogen-free CCLs and ordinary FR-4 CCLs is summarized into the following table. ...
Halogens are a group of highly reactive, nonmetal elements which include fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). Due to their reactivity, these elements are found only in nature as compounds and ions. Additionally, these elements form highly toxic and corrosive gasses when...
