This webpage contains pictures and links to video clips taken at the instruction
session for assembling ATLAS SCT Upgrade Strip Sensor Modules.
The aim of these videos and pictures is to illustrate the use of the various
jigs, templates as used in the assembly procedure, and the procedure itself.
The hybrid assembly procedure is detailed below, pictures and videos of the
module assembly can be found here.
