What does IPC/WHMA-A-620 specify?

IPC/WHMA-A-620 specifies requirements and acceptance criteria for cable and wire harness assemblies. This standard provides guidelines for the fabrication and assembly of wire harnesses, including detailed specifications for materials, workmanship, and the finished product's performance. It ensures that assemblers have a clear framework to follow, which leads to consistent quality across different manufacturing processes.

This standard covers aspects such as the acceptable range of wire sizes, insulation types, and assembly methods, making it essential for manufacturers to ensure that their products meet specific functional and safety requirements. By adhering to these guidelines, companies can reduce the risk of defects and ensure that their wire harness assemblies are reliable and durable in their intended applications.

Other options refer to standards that are not encompassed by IPC/WHMA-A-620. For instance, soldering practices, performance standards for rigid boards, and the acceptability of printed circuits are addressed in different IPC standards that focus on their respective areas.
