"2022国际标准：IPC/WHMA-A-620E线缆及线束组件的要求与验收"

WHMA-A-620E EN is a comprehensive standard outlining the requirements and acceptance criteria for cable and wire harness assemblies in 2022. This standard, developed by IPC, supersedes the previous version WHMA-A-620D from January 2020. The WHMA-A-620E EN standard lays out detailed guidelines and criteria for the manufacturing and inspection of cable and wire harness assemblies. It covers various aspects such as materials, design, construction, inspection, and testing to ensure the quality and reliability of the final product. One key aspect of WHMA-A-620E EN is the classification of acceptance criteria based on three classes: Class 1 for general electronic products, Class 2 for dedicated service electronic products, and Class 3 for high-performance electronic products. Each class has specific requirements and tolerances that must be met for the assembly to be considered acceptable. The standard also includes detailed illustrations and descriptions of acceptable and non-acceptable conditions for cable and wire harness assemblies. This helps manufacturers and inspectors to easily identify issues and discrepancies during the inspection process. Additionally, WHMA-A-620E EN includes requirements for documentation, labeling, and traceability of materials used in the assembly process. This ensures that the assembly can be traced back to its sources and that any issues can be easily identified and rectified. Overall, WHMA-A-620E EN is an important standard for manufacturers, inspectors, and users of cable and wire harness assemblies. By following the guidelines and criteria set forth in this standard, companies can ensure the quality and reliability of their products, leading to improved customer satisfaction and trust in the products they produce.
