PCB designers are familiar with the use of electronic tests verify the integrity of the circuit. However, RoHS testing is all about material. As a result most of the electronic components manufacturers are not equipped capable of detecting material found banned substances necessary equipment. Only reliable materials testing laboratory in order to do this kind of testing. If the circuit test passes, ROHS3000 maintenance and replacement, but not through materials testing, so the circuit board failed, ROHS, suppliers no use. HJ noted that the introduction of management practices and standards is to promote the electronic information industry restructuring, Tin Shui ROHS training, facilitating opportunities of product upgrades. He said Shui ROHS maintenance inspection, Electronic Information Products Pollution Control Regulations is China's RoHS; China RoHS core task is to substitution and reduction of hazardous substances in electronic information products. Lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6 +), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) is widely used in electrical and electronic products, it has been proved by modern science substances on human life and health damaging effects of the implementation of RoHS measures to protect the environment and human health needs. ROHS_ Shengding _ROHS3000 equipment maintenance and replacement provided by the Dongguan City Ding Sheng Precision Instrument Company. ROHS_ Shengding maintenance and replacement of equipment _ROHS3000 Dongguan City Ding Sheng Precision Instrument Co., Ltd.
