The products are marked with lead-free and RoHS. What standard does it mean?

The so-called RoHS refers to the Restriction of Hazardous Substances Directive (English: Restriction of Hazardous Substances Directive 2002/95/EC, abbreviated RoHS) is an environmental directive (but not a law) adopted by the European Union in February 2003. The main specification The object is the manufacturing limit of equipment with working voltage less than 1000V AC or 1500V DC, which is the engineering process standard for product composition and manufacturing.

The dosage of these six substances: • Lead (Pb) (0.1%) • Mercury (Hg) (0.1%) • Cadmium (Cd) with a maximum allowable content of 0.01% (100ppm). • Hexavalent chromium (CrVI) (0.1%) • Polybrominated biphenyls (PBB) (0.1%) • Polybrominated diphenyl ethers (PBDE) at a maximum allowable content of 0.1% (1000ppm). The latter two are usually used as flame retardants. In traditional production, lead is used to bond small solder balls to wafers and boards. Today's lead-free technologies no longer require lead and are replaced by alloys of tin, silver and copper. On 2015/03/31, the EU issued a directive to add 4 new restrictions on the use of phthalates: • Di(2-ethylhexyl) phthalate (DEHP) (0,1 %) • ortho Benzyl butyl phthalate (BBP) (0,1 %) • Dibutyl phthalate (DBP) (0,1 %) • Diisobutyl phthalate (DIBP) (0,1 %) All of our products have been introduced into this specification during production, including the post-processing wires that use halogen-free materials.

In addition, our company has also made a declaration of [Conflict Minerals Declaration]. Since the mineral transactions in the Democratic Republic of Congo have been controlled by local interest groups and belong to their main source of income, in order to obtain such benefits, in the process of mining minerals in this region, the Caused serious armed conflicts and human rights violations, and attracted the attention of the international community. In this regard, based on the position of respecting international human rights, regarding those metal minerals (hereinafter referred to as "conflict minerals") arising from armed conflicts and human rights violations, the following statement is hereby made: • Relevant measures will be taken to avoid the use of such conflict minerals in products, This includes requiring suppliers to investigate in detail whether the minerals containing gold (Au), tantalum (Ta), tin (Sn), and tungsten (W) metals in their products come from the Democratic Republic of Congo. • Suppliers are expected to fully use accredited and qualified smelters or require existing smelters to conduct relevant verification. If conflict minerals are found in their products, necessary measures will be taken to stop the use of such conflict minerals. We will continue to pay attention to the issue of conflict minerals in order to improve the impact of the issue of minerals.
