If you’re sourcing, assembling, or inspecting cable harnesses, understanding this standard is critical<\/strong> to ensuring product reliability and customer satisfaction.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n IPC\/WHMA-A-620<\/strong> is a joint standard developed by IPC<\/strong> (Association Connecting Electronics Industries) and WHMA<\/strong> (Wire Harness Manufacturers Association). It establishes visual acceptance criteria<\/strong> for:<\/p>\n \\n\\n<\/p>\n Crimped, mechanically secured, and soldered connections<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Wire preparation and termination<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Routing and securing of cables<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Insulation, shielding, and jacketing practices<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Connector assembly<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n It is used by manufacturers and quality inspectors to evaluate workmanship<\/strong> against agreed criteria across three classes of product:<\/p>\n \\n\\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/thead>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/tbody>\n \\n<\/table>\n \\n<\/p>\n \\n<\/p><\/div>\n \\n<\/p><\/div>\n \\n<\/p><\/div>\n \\n\\n<\/p>\n \\n<\/p>\n \u2705 Universal language for quality<\/strong> in cable harness assembly<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n \u2705 Enables OEMs and suppliers to align expectations<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n \u2705 Minimizes rework, warranty claims, and safety risks<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n \u2705 Required in many military, aerospace, and automotive contracts<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n \u2705 Provides training and certification programs<\/strong> for technicians and inspectors<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n\\n<\/p>\n \\n<\/p>\n The IPC\/WHMA-A-620 includes hundreds of high-resolution photos and illustrations<\/strong> that show acceptable and unacceptable workmanship for:<\/p>\n \\n\\n<\/p>\n Stripped wire ends<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Crimp terminations<\/strong> (open-barrel and closed-barrel)<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Soldered connections<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Shielded cable assemblies<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Heat shrink usage<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Routing and support of wires<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Cable ties and lacing techniques<\/strong><\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n It\u2019s regularly updated to reflect advances in materials and assembly methods. The current revision is IPC\/WHMA-A-620 Revision D<\/strong> (as of 2022), which includes updates for newer connector styles and process tolerances.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n Manufacturers, assemblers, and inspectors can take part in formal training courses to become Certified IPC Specialists (CIS)<\/strong> or Certified IPC Trainers (CIT)<\/strong>. These certifications validate that a person understands the standard and can apply it to real-world production or inspection.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n Industries that require strict quality control in wiring and harness assemblies:<\/p>\n \\n\\n<\/p>\n
