Description
The Belle-II experiment at the SuperKEKB collider in Japan will operate at
a luminosity approximately 50 times greater than its predecessor (Belle). At
its heart lies a six-layer vertex detector comprising two layers of pixelated
silicon detectors (PXD) and four layers of double-sided silicon microstrip
detectors (SVD). One of the key measurements for Belle-II is time-dependent
CP violation asymmetry, which hinges on a precise charged-track vertex
determination. Towards this goal, a proper assembly of the SVD components
with precise alignment ought to be performed and the geometrical tolerances
should be checked to fall within the design limits. We present an overview of
the assembly procedure that is being followed, which includes the precision
gluing of the SVD module components, wire-bonding of the various electrical
components, and precision 3D coordinate measurements of the jigs used in
assembly as well as of the final SVD modules.
