RoHs Lead Free
RoHs (Restriction of Hazardous Substances Directive 2002/95/EC) is an environmental directive (but not a law) passed by the European Union in February 2003.
The basic principle of RoHs is that from July 1st, 2006, all electronic devices introduced into the market must not contain lead or certain other harmful substances. This applies to the following products:
IT and telecommunication equipment
Electrical and electronic tools (except for large, stationary industrial devices)
Toys, recreational and sporting articles
Due to environmental issues,RCY provides service of manufacture printed circuit boards without lead for surface finish that requires rigorous concentration of 6 hazardous substances including Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (CrVI), Polybrominated Biphenyls (PBB) and Polybrominated Diphenyl Ethers (PBDE). Among the 6 types of substances, lead is the most widely applied in the electronic plating. Therefore, lead-free is the best way for surface finish of PCB.
Attached our Certificate of RoHs.
The PCB surface finish can be chosen by customers. In addition to HASL lead free, the following lead-free solutions are also available for PCB:
Immersion Gold (ENIG)
If you always order the boards with lead, you can choose one of lead-free solutions in the future.
