In the context of the Long Shutdown 3 around 2025 the current strip tracker of the CMS experiment will be replaced as required for the High Luminosity LHC (CERN) with a planned instantaneous luminosity of 5·1034 cm−2s−1. Around 8000 conceptually new silicon modules have to be built that will each be equipped with two identical vertically stacked silicon strip sensors. Through the difference in the hit position in the two sensors − caused by the magnetic field of 3.8 T inside the detector bending the tracks of charged particles − it is possible to select high transverse momentum tracks for the L1 trigger already on the module itself.
To manufacture these modules an assembly process is needed that guarantees high precision along with proper electrical isolation and can be realized with simple-to-use tools to facilitate mass production.
In this talk the current progress and selected challenges of the assembly will be presented.
