Space product assurance - The manual soldering of high-reliability electrical connections

Scope

This standard defines the technical requirements and quality assurance provisions for the manual soldering of high­reliability electrical connections intended for use in spacecraft and associated equipment.
The rigorous requirements set by this standard ensure the high reliability of hand­soldered electrical connections intended to withstand normal terrestrial conditions and the vibrational G­loads and environment imposed by space flight. The proper tools, correct materials, design and workmanship are covered by this standard. Acceptance and rejection criteria are stated and some workmanship standards are included to discriminate between proper and improper work.
Wave­soldering processes and surface mount technologies are specified in separate documents, and those processes require to be verified as prescribed in the respective standard.
