RoHS is a compulsory standard formulated by EU legislation. Its full name is "restriction of hazardous substances". The standard has been formally implemented since July 1, 2006. It is mainly used to standardize the material and process standards of electronic and electrical products, making it more conducive to human health and environmental protection.
The purpose of this standard is to eliminate six substances in electrical and electronic products, including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers (Note: the correct Chinese name of PBDE refers to polybrominated diphenyl ethers, and polybrominated diphenyl ethers is the wrong term), and the content of Lead shall not exceed 0.1%.
