        What is RoHS?

        The full name of RoHS is "Restriction of Hazardous Substances" (Restriction of Hazardous Substances). Mainly used to standardize the material and process standards of electronic and electrical products, making them more conducive to human health and environmental protection. The purpose of this standard is to eliminate lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs) in electrical and electronic products. ; On June 4, 2015, the European Union promulgated the RoHS2.0 revision directive to formally add 4 toxic and hazardous substances (DEHP, BBP, DBP, DIBP) to the scope of RoHS 2.0 control.
