Zero-Insertion-Force Connector Alignment Tool

      Disclosed is a device for precisely aligning the
Zero-Insertion-Force (ZIF) connectors in series on a circuit board
during assembly operations, such as soldering.

      For cards with a large number of I/Os (Input/Output), it is
necessary to use two or more ZIF connectors in series on a board.  In
such a layout, the perfect alignment of the card slots in the
connectors is important for the ease of card insertion and perfect
contact of all I/Os.  To achieve this, some kind of alignment device
is necessary for holding down the connectors in line during the
soldering operation.  Any attempt to achieve this by inserting the
tool in the connector slot involves the risk of cracking the
connector.  A carefully designed tool is necessary to apply the
pressure only at the sturdy part of a connector to achieve the
alignment and thus prevent the cracking of delicate parts of a
connector.

      The figure illustrates the parts and the arrangement of such a
tool, aligning two connectors A and B in series. Inverted "U" shaped
spring 3 along with long handles 1 form a clamp.  Thumbwheel 2 allows
the adjustment of the clamping force if required.  Alignment points 4
help verify the precise alignment by checking their coincidence with
the slots of connectors.  Extended pressure plates 6 at the bottom of
the clamp exert the pressure required for the alignment on the bottom
of the outer body which is the sturdiest part of...
