Which standard would you refer to for requirements on soldered electrical assemblies?

The correct choice is IPC J-STD-001, as this standard specifically outlines the requirements for soldered electrical and electronic assemblies. It provides comprehensive guidelines on materials, methods, and verification procedures for solder connections, ensuring the quality and reliability of soldered joints in various applications. This standard is fundamental for those who work in industries that involve soldering processes, as it encompasses criteria for different types of soldered connections, from basic through to advanced level requirements.

The other standards address different aspects of electrical assembly and manufacturing. IPC-A-600 focuses on the acceptability of printed boards, IPC-6012 pertains to the qualification and performance of rigid printed boards, and IPC/WHMA-A-620 covers the requirements for cable and wire harness assemblies. While they are relevant to electronic manufacturing, they do not specifically deal with the soldering processes that are emphasized in IPC J-STD-001.
