An Automated Silicon Module Assembly System for the CMS Silicon Tracker

The CMS Tracker requires the assembly of about 20000 silicon detector modules. To ensure the assembly of such a large quantity with high, reproducible quality, an automated system for module assembly has been developed based on a high-precision robotic positioning machine. This system allows a much higher throughput and will result in much reduced manpower requirements than for traditional manual techniques. This note describes the design and performance of the automated Silicon module assembly system which has been developed within the CERN CMS Silicon Tracker group.
