Abstract

IFAE is engaged in the production of linear triplet modules for the forthcoming upgrade of the Inner Tracker for the high luminosity phase of the Large Hadron Collider. The pre-production process requires the fabrication of early prototypes (the RD53A chip) to inform the assembly and electrical test methodologies. Module prototypes (also called triplets) include a set of 3 hybrids (sensors connected to readout chips), all of them are mounted in an individual flexible PCB. This document presents the assembly methodologies and main electrical tests results for the first set of 4 modules assembled at IFAE.
