The CDF Silicon Vertex Detectors (SVX) have been shown to be excellent tools for heavy flavor physics, with the secondary vertex detection and good vertex resolution.The CDF RunIIb Silicon Vertex Detector (SVXIIb) was designed to be a radiation tolerant replacement for the current SVXII which was not anticipated to survive the projected Run II luminosity dose. The outer five layers use identical structural elements, called staves, to support six silicon sensors on each side. The stave is composed of carbon fiber skins on a foam core with a built-in cooling tube. Copper on Kapton bus cable carriers power and data/control signals underneath three silicon modules on each side of the stave. A Hybrid equipped with four new SVX4 chips are used to readout two silicon sensors on each module which can be readout and tested independently. This new design concept leads to a very compact mechanical and electrical detecting unit, allowing streamline production and ease of testing and installation. A description of the design and mechanical performance of the stave is given. They also present here results on the electrical performance obtained using prototype staves as well as results with the first pre-production parts.
