The RoHS Reference Center, from Electronic Design, is designed to provide electronic design engineers with lead free information they need to specify or
purchase lead free electronic components in compliance with the Restrictions on Hazardous Substances directive - commonly known as the lead-free directive. The substances
covered by the RoHS Directive are scientifically well researched and evaluated
and have been subject to different measures both at community and at national level. Member States shall ensure that, from 1 July 2006, new electrical and electronic
equipment put on the market does not contain lead ("lead free"), mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).
