Robotic SIP Insertion Head

       A SIP (Single Inline Package) component insertion is
disclosed.  This SIP insertion head was designed to SIP insertion.
Basically, the head must be able to pick up a SIP and have a minimal
footprint (to collision with other components already in the

      Referring to the figure, the SIP insertion head 1 picks the
part with vacuum.  The vacuum chamber 4 and channel 2 electrical-
discharge machined to provide the largest area with the part and the
largest channel for flow insure quick grasping and to reduce effects
of air leakage between the head 1 and the  In addition, the design
has a tapered vacuum chamber that allows the end effector to have a
minimal footprint therefore minimum interference).  The vacuum
chamber 4 designed to only grip the side of the SIP.  The vacuum 4
has a thin rubber gasket 5 to insure a good seal.  The of the vacuum
grip with this design is high so that we can use the head 1 to
grip any size SIP the single vacuum port.

      Use of a single vacuum port for all size SIPs allows us pick
all SIPs up by their centers.  This means that rotations have a
constant offset and make the insertion tool, including the head 1,
simpler.

      A custom wing 3 that contacts the top of the SIP on the head
1 provides two point contact of the SIP.  This improved
perpendicularity of the SIP even if top is rounded.  The uses a
compliance sensor on insertion.  This bent leads.
