Panda PCB service our customers from prototype through mass production in Halogen-Free PCB, Now Halogen-Free PCB has recently been hot topic in the electronics industry due to increasing concern over environmental issues.In general as the term implies “ Halogen-Free” means the product material that does not contain any compounds derived from halogen elements. While it is not yet legislated that electronic component PCB suppliers must remove brominated and chlorinated flame retardants from their materials. In many applications a halogenated material can provide the required product performance at a lower overall cost than Halogen-Free PCB materials. Halogen Free PCB Development : Concerns regarding the health and safety of halogenated flame retardants in PWB applications dates to the early 1990s, when it was discovered that under certain circumstances highly toxic dioxins and furans could be released during the (incomplete) combustion of PWBs that use brominated flame retardant.

Halogen Free PCB Definition : According to IPC 4101B standards in the electronics industry that address Halogen-Free PCB:Ĭhlorine must be below 900 PPM by weight.Ĭombined Bromine + Chlorine must be below 1500 PPM by weight.ģ. In addition ,The dielectric constant, dissipation factor and moisture diffusivity of PCB materials that are described as Halogen-Free PCB are different from those employed in PCBs industry.Ģ. As such, Halogen-Free PCBs are becoming more and more popular because they are constructed of materials that are free of halogen. Halogenated compounds have been targeted for reduction and eventual elimination.
