Actually what you learn in this training is very diverse. Amongst other things, this will be what tools are used within the various operations that are applied to wire harness assemblies. In particular for the soldering and crimp processes and all other operations that are performed there.
This training discusses the materials used and their specific properties. Furthermore calibration of tools (as far as necessary) is discussed as well as is the correct handling of the tools, cleaning and such matters. So all general requirements for the processes and people who work on wire harness assemblies.
Also the criteria applicable for the end product before delivery are discussed and this for soldered connections, crimped connections that are used in wire harnesses as well as all further aspects of the assembly of the wire harness and all operations involved and how the finished product will have to look like.
