What is RoHS?
What is RoHS?
RoHS stands for Restriction of Hazardous Substances. RoHS, also known as Directive 2002/95/EC, originated in the European Union and restricts the use of specific hazardous materials found in electrical and electronic products (known as EEE). All applicable products in the EU market after July 1, 2006 must pass RoHS compliance.
What are the restricted materials mandated under RoHS?
The substances banned under RoHS are lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and four different phthalates (DEHP, BBP, BBP, DIBP).
Why is RoHS compliance important?
The restricted materials are hazardous to the environment and pollute landfills, and are dangerous in terms of occupational exposure during manufacturing and recycling.
Due to environmental issues, AlteraFlex provides service of manufacture printed circuit boards without lead for a 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 the surface finish of the PCB.
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)
Immersion Silver
Immersion Tin
Hard Gold
OSP
If you always order the boards with lead, we recommend you can choose one of the lead-free solutions in the future.
