Description
In the last year the CMS experiment has constructed and integrated the largest
ever build full silicon strip tracker. Therefore the CMS tracker collaboration
set up a unique scheme of quality control to ensure the necessary high quality
of all of the 15,148 modules and their super structures. The applied scheme
of quality control revealed several problems, which escaped the initial R&D
phase, ranging from corrosion effects on the silicon, capton and via problems
on the front end hybrids up to aging conductive glue. An overview of the
construction and qualification experience is given, discussion the ma jor steps
which result in the unique experimental device, which the CMS tracker is
currently commissioning.
