With the High-Luminosity upgrade of the Large Hadron Collider (HL-LHC), the innermost layer of the ATLAS detector will be replaced by a new Inner Tracker (ITk) pixel detector. The University of Siegen contributes to this upgrade by producing quad modules for the outer barrel region of the pixel detector. A quad module is designed as a hybrid structure consisting of a flexible printed circuit board (PCB) glued onto a bare module in a cleanroom environment. That bare module is composed of a silicon-based sensor and four front-end readout chips (FEs). Electrical connection between the FEs and the PCB is provided by about 700 wirebonds. Extensive quality control (QC) procedures are performed before and after assembly, including metrology, visual inspections, and electrical characterization. In this contribution, the production chain of quad modules at the University of Siegen will be presented, with focus on the non-electrical aspects of the QC workflow.
