亚博提款要一倍流水for people in the electronics industry, rohs-printed electronic devices are often received on the box, but many people don't know the meaning of rohs. why do fets, diodes, transistors, chips and other electronic products best pass this standard?
first, explain what is the rohs issue. rohs is an abbreviation for “restrictions on the use of certain hazardous substances in electrical and electronic equipment”. this is an international standard and the rohs standards adopted by countries all over the world are based on the iec62321 standard. in the european union, this standard is a mandatory standard, but in china, certain countries such as the united states and japan are voluntary certification standards.
Tongshunda MOSFET passed RoHS test certificate
the reason for the introduction of this standard was that in 2000, the netherlands discovered cadmium in the cables of many commercially available game consoles, and for the first time noticed that electrical and electronic equipment contained heavy metals harmful to human health, so the standard came into being. once introduced, the standard became popular worldwide and the eu countries became mandatory standards. in 2004, the ministry of information industry of china also issued the “measures for prevention and control of pollution of electronic information products”, which is similar to rohs and is mainly used for pollution prevention and control of electronic information products.
as field effect transistors, transistors, diodes, chips and other devices widely used in a variety of electrical equipment, in addition to silicon, a variety of metals have appeared on certain pins, connection pads and printed packaging materials. to ensure that these parts are made of non-hazardous materials, it is recommended to pass the rohs test.
