Microwire Carrier Handling Positioning and Alignment

      Accurate positioning and alignment of microwire carrier is
achieved by frame-carrier assembly which is magnetically held to an
extended arm mounted to an X-Y-Z stage positioner.

      The problem to be solved is related to many packaging
applications where there is an increasing need to perform
interconnections  between  circuitry  elements  having micron-level
dimensions. For example, opens in lines need to be repaired and EC
wiring under the chip needs to be performed in thin film modules.
This packaging environment requires extremely precise accuracy and
care in handling, positioning and alignment of the fine wires (a
fraction of human hair) used to make the interconnection.  To avoid
handling damage of the microwires the CARRIER holding the microwires
is mounted on a metal window FRAME made of a magnetic material such
as steel. Mounting of the carrier to the frame can be accomplished by
simply using a suitable adhesive.  As shown in Figure 1, in order to
manipulate a wire into position an extended ARM attached to an X-Y-Z
STAGE is used to hold the FRAME-CARRIER ASSEMBLY (see Figure 1) by
magnetic force. Magnetic holding is done by attaching to the arm a
magnetic surface shaped to reproduce exactly the shape and dimensions
of the FRAME.  Magnetic force provides an extremely simple way of
holding and removing of the frame.
