RoHS Compliance: A Global Imperative
Explore the global significance of RoHS and its impact on electronics
What is RoHS？
RoHS stands for “Restriction of Hazardous Substances.” It is a regulatory directive that has had a significant impact on the entire electronics and electrical products industry. The original RoHS, also known as Directive 2002/95/EC, was introduced by the European Union in 2002. It aimed to restrict the use of six hazardous substances in electronic and electrical products. Since July 1, 2006, all products intended for the European Union market must comply with RoHS requirements.
Directive 2011/65/EU, released by the European Union in 2011, is commonly referred to as RoHS-Recast or RoHS 2. RoHS 2 incorporates the CE marking directive, making it mandatory for products carrying the CE mark to comply with RoHS requirements. Additionally, RoHS 2 introduced the 8th and 9th categories and introduced additional documentation requirements for compliance.
Directive 2015/863, known as RoHS 3, expanded the list of restricted substances by adding four phthalates to the original six hazardous substances.
It’s important to note that China’s test labs do not currently have the RoHS 3.0 test standard. As a result, companies like Topdiode and UF Capacitors declare their products as RoHS 2.0 compliant and plan to update their certifications in accordance with the latest regulations.
RoHS compliance is crucial for businesses selling electrical and electronic products in RoHS-directed countries, as well as those selling to resellers, distributors, or integrators serving these countries. This regulation covers a wide range of products, from mobile devices to IoT devices, smart home assistants, robots, drones, 3D printers, and medical devices.
EU RoHS outlines maximum allowable levels for ten restricted substances. The initial six were introduced with the original RoHS, while the latter four were added under RoHS 3, which came into effect on July 22, 2019.
Cadmium (Cd): < 100 ppm
Lead (Pb): < 1000 ppm
Mercury (Hg): < 1000 ppm
Hexavalent Chromium (Cr VI): < 1000 ppm
Polybrominated Biphenyls (PBB): < 1000 ppm
Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
Benzyl butyl phthalate (BBP): < 1000 ppm
Dibutyl phthalate (DBP): < 1000 ppm
Diisobutyl phthalate (DIBP): < 1000 ppm
Will RoHS impact the Quality of PCBs？
RoHS does not directly affect the quality of PCBs, as it is not a quality standard. Simply being RoHS compatible does not inherently improve the quality of a board. However, RoHS, often referred to as “lead-free,” does have a significant impact on PCB fabrication and soldering processes.
The transition to lead-free soldering, as mandated by RoHS regulations, necessitates changes in the PCB manufacturing process. Soldering at higher temperatures can potentially affect the PCB materials and components. Therefore, new FR-4 materials have been developed to withstand these higher temperatures without compromising the overall product’s lifespan and quality.
In summary, while RoHS compliance itself doesn’t enhance PCB quality, it does introduce changes in manufacturing processes to ensure that lead-free soldering requirements are met without compromising the reliability and performance of the final product.
Why is RoHS compliance important?
RoHS compliance is crucial for protecting the environment, promoting worker health and safety, accessing key markets, enhancing brand reputation, fostering innovation, and staying ahead of regulatory changes.
- Environmental Protection: RoHS regulations, also known as the Lead-Free Directive, are designed to reduce environmental pollution caused by toxic electronic waste. Even small amounts of restricted elements like lead, mercury, and cadmium can be harmful to plants, animals, and ecosystems. Compliance with RoHS helps prevent the pollution of soil, air, and water sources, safeguarding wildlife and public health. Lead-free PCBs are also easier to recycle, reducing electronic waste and conserving valuable electronic resources.
- Worker Health and Safety: Prolonged or short-term exposure to lead, as found in lead-based solder, can have severe health consequences, including headaches and fertility issues. Complying with RoHS regulations protects the health and safety of workers involved in PCB assembly and recycling, as well as vulnerable populations, including children, living near manufacturing facilities.
- Market Access: Non-compliance with RoHS regulations can have significant business implications. Selling products that do not meet RoHS requirements is prohibited in the European Union and California, two substantial markets. Ensuring RoHS compliance allows companies to access these lucrative markets, boosting profitability and expanding their customer base.
- Legal Compliance: RoHS regulations are legally binding in many regions, and non-compliance can result in fines, legal actions, and damage to a company’s reputation. Adhering to RoHS standards ensures that a business operates within the bounds of the law.
In conclusion, RoHS compliance not only benefits the environment and public health but also opens doors to key markets, safeguards worker well-being, and ensures legal adherence. It is a vital aspect of responsible and sustainable electronics manufacturing.
RoHS Compliance FAQ
1
Which companies are affected by the RoHS Directive?
Any business that sells or distributes applicable EEE products, sub-assemblies, components, or cables directly to EU countries, or sells to resellers, distributors, or integrators that, in turn, sell products to EU countries, is impacted if they utilize any of the restricted materials. Since RoHS-like regulations have spread to a number of other countries, this doesn’t apply to EU countries alone.
RoHS also applies to the metal industry for any application of metal plating, anodizing, chromating, or other finishes on EEE components, heatsinks, or connectors.
2
How are RoHS and WEEE related?
WEEE is the acronym for Waste from Electrical and Electronic Equipment. WEEE, also known as Directive 2002/96/EC, mandates the treatment, recovery and recycling of electric and electronic equipment. All applicable products in the EU market after August 13, 2006 must pass WEEE compliance and carry the “Wheelie Bin” sticker. WEEE compliance aims to encourage the design of electronic products with environmentally-safe recycling and recovery in mind. RoHS compliance dovetails into WEEE by reducing the amount of hazardous chemicals used in electronics manufacture.
Put another way, RoHS regulates the hazardous substances used in the manufacture of electrical and electronic equipment (EEE), while WEEE regulates the disposal of this same equipment.
3
Does RoHS apply to RFID tags?
Yes, both passive and active RFIDs are covered by RoHS. For packaging purposes, they are categorized under Category 3. When RFID tags are permanently affixed to equipment or devices, they fall under the category of the parent device.
4
Do RoHS Regulations Apply Only in the European Union (EU)?
No, RoHS-like regulations have been adopted by many countries and regions worldwide. While the original RoHS Directive (Directive 2002/95/EC) was introduced in the EU, similar regulations have been implemented in the United States, China, Japan, South Korea, and other regions.
5
How Can a Business Ensure RoHS Compliance?
- Source RoHS-compliant components and materials.
- Conduct testing and documentation of materials and products.
- Implement a compliance management system.
- Stay informed about regulatory changes and updates.
- Collaborate with suppliers to ensure compliance throughout the supply chain.
- To ensure RoHS compliance, businesses should:
6
