RoHS stands for hazardous substance restriction. RoHS, also known as Directive 2002/95/EC, originated in the European Union and restricts the use of certain hazardous materials found in electrical and electronic products (known as EEE). All applicable products on the EU market after July 1, 2006 must pass RoHS compliance.
What are the restricted materials specified by RoHS?
The substances prohibited by 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?
Restricted materials are harmful to the environment and pollute landfills, and are dangerous in terms of occupational exposure during manufacturing and recycling.
Due to environmental problems, Jingbang provides lead-free PCBA circuit board manufacturing services. Its surface finish requires strict concentration of six harmful substances, including lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE). Among the six substances, lead is the most widely used in electronic electroplating. Therefore, lead-free is the best way of PCBA surface finish.
Our RoHS certificate.
PCBA production surface finish can be selected by customers. In addition to HASL lead-free, PCB also provides the following lead-free solutions:
ENIG
Sink silver
Tin precipitation
Hard gold
operating system
If you always order leaded PCBA circuit boards, we suggest you choose one of the lead-free solutions in the future.
