RoHS란?
RoHS : Directive on the Restriction of the use of certain Hazardous Substances in the electrical and electronic equipment
※ A regulation restricting the use of hazardous substances in electrical and electronic products.
RoHS 목적
- Restricting the use of hazardous substances
- Legal provisions covering hazardous substances among UN member states
RoHS 시행일
- Applies to the specified hazardous substances in electrical and electronic products from 1 July 2006 (at customs clearance)
RoHS 주요 내용
- From 1 July 2006, electrical and electronic products containing any of six substances — lead, cadmium, mercury, hexavalent chromium, PBB or PBDE — above the permitted values may not be placed on the market.
- Legal provisions covering hazardous substances among UN member states
규제물질 허용값
| 유해물질 | 농도 제한 |
|---|---|
| Lead (Pb) | 1,000 ppm |
| Cadmium (Cd) | 100 ppm |
| Mercury (Hg) | 1,000 ppm |
| Hexavalent Chrome (Cr6+) | 1,000 ppm |
| PBB (Br) | 1,000 ppm |
| PBDE (Br) | 1,000 ppm |
RoHS2란?
RoHS2 목적
- To control the environmental contamination caused by waste from hazardous substances in electrical and electronic products sold in the EU, and to increase rates of recycling and reuse.
- To improve the environment by restricting hazardous substances and requiring the use of substitutes

할로겐 프리란?
Most halogen elements — Br, Cl, F, I and At — are toxic and react readily with alkali metals to form halogen compounds. Regulation therefore focuses mainly on bromine and chlorine, with the remaining elements covered in some cases.
사용 목적
- PVC (polyvinyl chloride)
- BFR (Brominated Flame Retardants)
사용 부위
Most likely to be found in polymer materials for PCBs (TBBP-A), connectors, ICs, PVC, wires, tubes, tape gaskets and optical sheets.
규제 가이드라인 및 기업 동향
- IEC / IEC 61249-2-21
- JPCA / JPCA-ES-01-2003
- PVC regulation in Texas, USA in 2008
- Sony has produced halogen-free PCBs since 2004.
- Samsung and some LG divisions have introduced their own domestic requirements
규제물질 허용값
| Harmful Substance | Concentration Limit |
|---|---|
| Bromine (Br) | 900 mg/kg maximum |
| Chlorine (Cl) | 900 mg/kg maximum |
| Total halogens | 1,500 mg/kg maximum |
