CLC/TC 107X - CLC/TC 107X
To develop process management standards on systems, components and equipment used in the field of avionics. Avionics includes electronics used in commercial, civil and military aerospace applications. The work of TC 107X will take into account the special European needs e.g. in the field of ecological and environmental concerns such as disposal or recycling of electronic equipment, including the previous work items of BTTF 91-3 and BTTF 101-3. Furthermore, CLC/TC 107X is to ensure that the specific European requirements will adequately be reflected in IEC/TC 107.

General Information
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 wirewrapped 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). Only tested and qualified wirewrapped connections are covered by this standard, which lists four wire sizes from 24 AWG to 30 AWG, and three terminal post sizes up to 1,78 mm maximum diagonal. The use of thicker wire and larger terminals are not advised. Thicker wire than 24 AWG is generally multistranded and terminated by soldering (see ECSS Q 70 08) or by crimping (see ECSS Q 70 26). Training and certification requirements for operators and inspectors are defined in 9.7 and in EN 13291 1.
