  We present the design of a detector used as a particle tracking device in the
STAR experiment at the RHIC collider of Brookhaven National Laboratories. The
"stave," 24 of which make up the completed detector, is a highly mechanically
integrated design comprised of 6 custom silicon sensors mounted on a Kapton
substrate. 4608 wire bonds connect these sensors to 36 analog front-end chips
which are mounted on the same substrate. Power and signal connectivity from the
hybrid to the front-end chips is provided by wire bonds. The entire circuit is
mounted on a carbon fiber base co-cured to the Kapton substrate. We present the
unique design challenges for this detector and some novel techniques for
overcoming them.
