Connector Orientation Method
A magnetic field can be used to maintain alignment of electrical connectors
in a circuit board when a neighboring connector is being unsoldered.
Referring to the figure, electromagnets 1 and 2, energized by power source
3, establish a vertical magnetic flux field surrounding connectors 4 that are
arranged in close proximity to one another. This field maintains the orientation of
the connectors bv preventing rotation while a connector, such as 5, is being
unsoldered by hot gas from nozzle 6 and then removed by grip head 7. Although
the hot gas softens the solder at the base of adjacent connectors, the magnetic
field assures their proper alignment during the unsoldering period. The
connectors may be made of a magnetic material or be merely plated with such a
