Product Details

Original NASA Reliability and Quality Assurance Publication: Requirements for Soldered Electrical Connections (NHB 5300.4(3A), May 1968). Issued during the Apollo program, this technical manual set the official soldering standards for spacecraft wiring, avionics, and launch systems. Superseding earlier guidelines (NPC 200-4, NMI 5330.3, and 5330.4A), this manual defined inspection criteria, acceptance/rejection standards, and preparation methods that were mission-critical for Apollo contractors. Content covers: Fabrication & conformal coating of printed wiring assemblies Turret, bifurcated, hook, pierced, and swaged solder terminals Lap joints & insulation tubing application Inspection & rejection criteria for manned spaceflight reliability Guidance for automatic machine soldering & in-house certification Illustrated throughout with technical diagrams and soldering cross-sections, including “preferred” vs. “unacceptable” connections. A fascinating Apollo-era artifact blending aerospace engineering precision with Cold War urgency. Condition: VG vintage; three-hole punched for contractor binders. Has a few stray marks on the cover, but complete and intact with strong covers. Professional packaging always, since 2003. #NASA #ApolloEra #ApolloProgram #SpaceCollectibles #NASAHistory #Apollo11Anniversary #SpaceRace #EngineeringHistory #VintageNASA #SpaceMemorabilia
