P.Production, quality assurance and quality control of the SiPM Tiles for the DarkSide-20k Time Projection ChamberART-2025-147632The DarkSide-20k dark matter direct detection experiment will employ a 21 m2 silicon photomultiplier (SiPM) array, instrumenting a dual-phase 50 tonnes liquid argon Time Projection Chamber (TPC). SiPMs are arranged into modular photosensors called Tiles, each integrating 24 SiPMs onto a printed circuit board (PCB) that provides signal amplification, power distribution, and a single-ended output for simplified readout. 16 Tiles are further grouped into Photo-Detector Units (PDUs). This paper details the production of the Tiles and the Quality Assurance and Quality Control (QA-QC) protocol established to ensure their performance and uniformity. The production and QA-QC of the Tiles are carried out at Nuova Officina Assergi (NOA), an ISO-6 clean room facility at LNGS. This process includes wafer-level cryogenic characterisation, precision die attaching, wire bonding, and extensive electrical and optical validation of each Tile. The overall production yield exceeds 83.5%, matching the requirements of the DarkSide-20k production plan. These results validate the robustness of the Tile design and its suitability for operation in a cryogenic environment.2025http://zaguan.unizar.es/record/16801310.1140/epjc/s10052-025-14940-1http://zaguan.unizar.es/record/168013oai:zaguan.unizar.es:168013info:eu-repo/grantAgreement/ES/AEI/PID2022-138357NB-C22The European Physical Journal C 85, 11 (2025), 1334 [27 pp.]byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
