PCB related certification

I. UL Certification

UL's full name is Underwriters Laboratories Inc, the acronym for Insurance Safety Laboratories Inc. Originated in the United States, it has since become the world's largest, longest-established and most prestigious safety certification organization in the world.

UL certification services are classified according to requirements: listing, accreditation, classification

**The UL Listing Mark on a product means that the manufacturer has allowed UL to test the sample to U.S. recognized safety standards and that, under reasonable and foreseeable circumstances, the sample will not cause fire, leakage or related hazards.

**Recognized Component**: Recognized component service that tests non-finished products such as parts and components that will be used in UL-listed products. For example, the UL certification of PCBs generally falls into this category. The most seen in our PCB is also RU MARK.

**Classification (Classification)**: Classification certification in industrial or commercial products tested usually have specified properties, including flammability, performance under hazardous conditions or special specifications required by the government, UL product classification is based on different properties, specified hazardous areas or specific conditions to test products, generally common products for construction materials or industrial equipment.

In the case of PCB factories, as consumers are most concerned about whether the factory has UL certification, whether the substrate/PP/solder-resistant ink manufacturers in our PCBs are in the factory's UL list. Each legitimate board factory will have a unique UL number, and in the UL website can be found above the number of this certificate. You can see the relevant information from the certificate.

II. ISO 9001

ISO 9001 is an international standard for quality management that can be certified by the International Organization for Standardization. ISO 9001 can be certified for any organization, size, product or service.

The purpose of implementing ISO 9001 is to maintain the quality of products and services and to ensure consistency of quality.

III. ISO 14001

ISO 14001 is also developed and published by the International Organization for Standardization, with the aim of helping enterprises to better control costs, protect the environment and productivity balance, and improve the overall competitiveness of enterprises, that is, ISO 14001 certification focuses on strengthening management, reducing costs, and reducing environmental pollution.

As countries around the world pay more attention to environmental protection, more and more first-class enterprises have taken environmental protection as their own responsibility, and require suppliers to also pay attention to environmental protection work.

The advantages brought by ISO 14001 environmental management certification, such as proof that the company's products are environmentally friendly products to improve market competitiveness, easier to export trade in the international market, especially in the highly polluting PCB manufacturing industry, through the ISO 14001 certification can effectively establish the corporate image and improve the visibility of enterprises.

IV. IATF 16949

IATF 16949 (formerly ISO/TS 16949 certification has lapsed in September 2018) refers to the quality management system - the automotive industry production and related services organizations to implement the special requirements of ISO 9001, developed by the International Automotive Task Force (International Automotive Task Force It is a highly customer-oriented and innovative certification, based on ISO 9001 : 2015, with an emphasis on incorporating the specific technical requirements of the automotive industry, in order to provide better quality products to customers in the global automotive industry and to develop a common system of quality management requirements for the automotive industry, focusing on defect prevention and reducing quality fluctuations and waste that can easily occur in the automotive parts supply chain. The members include international automobile manufacturing organizations and organizations related to automobile trade in various countries.

V. RoHS

RoHS (Restriction of Hazardous Substances) is a mandatory standard set by the European Union legislation, the Chinese name is the "Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment". The standard has been officially implemented since July 2006, mainly for the regulation of electrical and electronic products, materials and technical standards, so that it is more conducive to human health and environmental protection.

The purpose of the standard is to eliminate lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers and four plasticizers in electrical and electronic products, a total of 10 substances, and the focus on the content of lead can not exceed 0.1%.

VI. REACH

REACH is an EU safety regulation involving the registration, evaluation, authorization and restriction of chemicals. Since June 2007, substances imported into the EU are required to be authorized. Manufacturers and importers must register with the European Chemicals Agency (ECHA) for goods imported into the EU with an annual import volume of 1 ton or more (including 1 ton). If the substances imported into the EU are classified as SVHC, authorization will be required and the manufacturer or importer must notify the European Chemicals Agency (ECHA) if any SVHC exceeds 0.1% and the annual import volume of the substance exceeds 1 tonne. The aim is to protect human health and environmental safety, and to maintain and improve the competitiveness of the EU chemical industry.

The main difference between RoHS and REACH is that RoHS prohibits the use of substances listed in the guidelines for electronic devices, while REACH is concerned with all chemicals used in the manufacture of products, which may include substances, solvents, coatings, chemicals, etc.
