Four items of RoHS

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, so as to make them more conducive to human health and environmental protection. The purpose of this standard is to eliminate 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 wrong) in electrical and electronic products. It is emphasized that the content of lead should not exceed 0.1%.
