CE certification is essential for PCB products that are sold within the European Union. It indicates that the product meets the essential health, safety, and environmental protection requirements. To obtain CE certification for PCB products, specific documentation needs to be prepared.

　　Technical Documentation

　　The manufacturer must compile comprehensive technical documentation that details the design, construction, and operation of the PCB product. This includes circuit diagrams, which show the electrical connections and components on the PCB. The bill of materials (BOM) is also crucial, as it lists all the components used in the PCB, including their specifications, suppliers, and part numbers. Additionally, the technical documentation should include a description of the manufacturing process, quality control procedures, and any relevant test reports. For example, if the PCB has undergone electromagnetic compatibility (EMC) testing, the test reports should be included to demonstrate compliance with EU EMC directives.

　　Declaration of Conformity

　　A Declaration of Conformity is a key document in the CE certification process. In this declaration, the manufacturer states that the PCB product complies with all the relevant EU directives and harmonized standards. The declaration should be signed by a person with the authority to make such a statement on behalf of the company. It should include details such as the product name, model number, serial number (if applicable), and the specific EU directives and standards that the product meets.

　　User Manual and Safety Instructions

　　The PCB product must be accompanied by a user manual and safety instructions in the languages required by the target EU markets. The user manual should provide clear and detailed information on how to install, operate, and maintain the PCB. Safety instructions should highlight any potential hazards associated with the product, such as electrical shock risks or precautions when handling the PCB. These documents need to be written in a language that is easily understandable by the end - user and should comply with EU regulations regarding the clarity and comprehensiveness of safety information.

　　Proof of Testing

　　As part of the CE certification, the PCB product may need to undergo various tests, such as EMC testing, safety testing, and environmental testing. The manufacturer must provide proof of these tests, which could be in the form of test certificates issued by accredited testing laboratories. These certificates should clearly state the test methods used, the results obtained, and that the product meets the relevant EU standards.
