NASA-STD-8739.3 (W/ CHANGE-3), NASA TECHNICAL STANDARD: SOLDERED ELECTRICAL CONNECTIONS (06-JUN-2008) [S/S BY IPC J-STD-001ES AND NASA-STD-8739.6]

NASA-STD-8739.3 (W/ CHANGE-3), NASA TECHNICAL STANDARD: SOLDERED ELECTRICAL CONNECTIONS (06-JUN-2008) [S/S BY IPC J-STD-001ES AND NASA-STD-8739.6]., NOTE: ASA has adopted IPC J-STD-001ES for all Programs and Projects, effective on October 17, 2011. The NASA standards for soldering, NASA-STD-8739.2 and NASA-STD-8739.3, are cancelled as of October 17, 2011. NASA-STD-8739.6, Implementation for NASA Workmanship Standards was published in 2012 to provide additional instructions for implementation of J-STD-001ES on NASA Programs. This publication sets forth requirements for hand and wave soldering to obtain reliable electrical connections. The prime consideration is the physical integrity of solder connections. Special requirements may exist that are not covered by or are not in conformance with the requirements of this publication. Engineering documentation shall contain the detail for such requirements, including modifications to existing hardware, and shall take precedence over appropriate portions of this publication when approved in writing by the procuring NASA Center prior to use (Requirement). This publication applies to NASA programs involving soldering connections for flight hardware, mission critical ground support equipment, and elements thereof, and wherever invoked contractually. This publication does not define the soldering requirements for Surface Mount Technology (SMT).
