Conflict Metal means metals of gold (Au), tantalum (Ta), tungsten (W), cobalt(Co), tin (Sn) and so on are derived from or sourced from mines in conflict areas of the Democratic Republic of Congo (DRC), or illegally taxed on trade routes, either of which are controlled by non-governmental military groups, or unlawful military factions. KnownPCB banned to use conflict metals and expects our suppliers to comply with the Electronic Industry Citizenship Coalition (EICC) Code of Conduct and to only source materials from environmentally and socially responsible suppliers and require all vendors purchase and use conflict-free metals, and priority source from smelters listed in EICC-GeSI Conflict-Free Smelter(CFS).
Therefore We KnownPCB will commit to the sourcing of “Conflict Free Minerals” through our suppliers to comply with the regulations with Conflict minerals.
