This Standard has been cancelled and replaced by ECSS-Q-ST-70-30C (31 July 2008).
Scope
This Standard specifies the methods for preparing and assembling the parts to be joined by wire wrapping, and the selection, calibration, use and certification of the wire wrapping tools.
The required wire-wrapped connections are illustrated in Figure 1.
This type of connection is similar to “Class A preferred” or “modified” connection detailed in MIL–STD–1130, and NASA NHB 5300.4(3H).
<p”>Only tested and qualified wire-wrapped connections are covered by this Standard, which lists four wire sizes from24 AWG to 30 AWG, and three terminal post sizes up to 1,78 mm maximum diagonal.
The use of heavier gauge wire and larger terminals is not absolutely prohibited, but it is considered unlikely that wire-wrapping would be chosen here, as the electrical interconnection technique. It is anticipated that wire larger than 24 AWG will be multistranded and terminated by soldering to ECSS-Q-70-08, or crimping to ECSS-Q-70-26.
Training and certification requirements for operators and inspectors are defined in subclause 9.7 and in ECSS-Q-20.
