Abstract
The ATLAS Strip Tracker for HL-LHC is composed of individual modules that contain silicon sensors and front-end electronics. These modules are then mounted onto carbon-fiber substructures, hosting up to 14 modules per side. At the end of these substructures, an EoS card connects up to 28 data lines to the lpGBT ASICs and the VTRX+ module, which provide data serialization and 10 Gb/s optical data transmission to the off-detector systems, respectively. The EoS card is powered by a dedicated Dual-Stage DC-DC converter. With the EoS project moving into the production stage, this contribution summarizes the quality assurance and quality control performed during the pre-production phase.
