        Author:中認聯(lián)科 time:2020-08-31 Ctr:2716

        The USB fan is a miniature electric fan used in the USB interface of a desktop computer or a notebook computer. The new type of brushless DC motor fan is quieter, more power-efficient, and has a longer lifespan than traditional motor fans. The following is a related introduction on the handling of RoHS testing for small fans.

        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.

        Why do small USB fans need to be tested for RoHS

        1. RoHS testing is to detect substances that are harmful to human health in these electrical and electronic equipment through professional institutions or instruments. When products are sold on the market, they can ensure that the products are safer and healthier during use.

        2. RoHS testing is the management of the green supply chain, which reduces the use of harmful substances and greatly improves the green competitiveness of products. It is an important symbol of environmental protection.
