The RoHS (Restriction of Hazardous Substances) directive (directive 2011/65/EU) restricts using certain hazardous substances in electrical and electronic equipment. The goal of RoHS is to reduce the environmental impact of electronic components and to protect human health by limiting the use of substances like lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs) and more.
The RoHS directive prioritizes the environmental and health aspects of the electronic parts over their overall quality.
Compliance with the directive
Compliance with RoHS regulations doesn't necessarily imply better or worse quality in terms of performance or reliability. Instead, it indicates that the components and materials used in the product do not contain specific hazardous substances above the defined limits.
The quality and reliability of electronic components depend on various factors, including design, manufacturing processes, materials used, and compliance with industry standards and specifications. RoHS observance is just one aspect of ensuring that electronic products are environmentally friendly and safe. It doesn't provide a direct measure of the overall quality or performance of the components.
The RoHS vs quality
The RoHS vs quality. Reliability is predicted based on the quality of parts and various criteria to ensure adequate performance and safety.
Manufacturers can produce high-quality components that are both RoHS-compliant and meet stringent performance standards. Conversely, non-RoHS-compliant parts may still be of high quality, but they may pose environmental and health risks due to hazardous substances.
Summary
While RoHS compliance is essential for environmental and health reasons, it doesn't inherently determine the overall quality of electronic components.
When assessing the quality and reliability of electronic products, it is essential to consider a broader set of criteria than just RoHS compliance.
