The assembly of the silicon modules for the ZEUS Micro Vertex Detector

For the luminosity upgrade of the HERA ep collider the ZEUS experiment is constructing a precision vertex detector. The interaction region will be surrounded with single-sided, AC-coupled, Si microstrip detectors with capacitive charge division: a 60 cm long cylinder with 600 silicon detectors arranged around the beam pipe in the central part and a four circular shaped disks (112 detectors) in the forward part. After a short introduction on the detector design, the experience gained during the assembly of the silicon modules of the central part is presented.
