Backforce
Backforce is a feature that compensates for the unnecessary application of downward pressure on the tool during wire wrapping. A wire wrapping tool will perform the wrapping function properly without any downward pressure applied, in fact, such pressure results in a tendency to overwrap (refer to Section entitled Wire Wrapping Technology for further details). A tool with the backforce option contains a spring mechanism to absorb downward pressure that an unskilled operator might apply.
