LHCb Silicon Tracker electronics: from R&D to preproduction

The LHCb Silicon Tracker consists of the Trigger Tracker located in front of the magnet and the Inner Tracker behind the magnet. While both tracking stations have a quite different appearance due to geometrical constraints, the basic working principle and building blocks for sensors and electronics are identical therefore simplifying R&D and upcoming production. This paper describes the development and transition to the preproduction phase of the Silicon Tracker components with focus on the electronic modules. We present the final mechanical design of the detector modules for both the Trigger Tracker and the Inner Tracker and the design of the associated readout hybrids. In addition, performance data for the first preseries of digitizer boards for the Silicon Tracker is shown and short information about electronic modules under common development within LHCb is given.
