PCB manufacturer China:What is Halogen Free PCB Board?
Many customers will ask PCB manufacturers China to make Halogen Free PCB Board. Halogen Free PCB Board is an environmentally friendly material, and the substrate used for Halogen Free circuit board is processed with Halogen Free raw materials.
Electronic devices contain certain materials that contain the highest concentrations of halogens. In order to create a Halogen Free circuit board in electronic equipment printed boards, it is necessary to replace certain materials or reduce their use on the board. It is also necessary to determine the halogen-free content of the circuit. Some alternative substances require special design considerations, which ultimately need to be considered as well.
At present, the vast majority of halogen-free sheets are mainly phosphorus-based and phosphorus-nitrogen-based. When the phosphorus-containing resin is burned, it is thermally decomposed to generate metaphosphoric acid, which has strong dehydration, and forms a carbonized film on the surface of the polymer resin, which isolates the burning surface of the resin from contact with the air, so that the fire is extinguished and the flame retardant effect is achieved. The polymer resin containing phosphorus and nitrogen compounds produces non-combustible gas when burning, which helps the resin system to flame retardant.
