Hybrid production status of the CMS Outer Tracker for the Phase-2 Upgrade
The CMS Collaboration will exchange the whole silicon tracking system as part of the Phase-2 Upgrade. About 8 000 two co-planar strip sensor (2S) modules and 5 880 macro-pixel and strip sensor (PS) modules will be built for the new Outer Tracker, requiring 47 520 hybrid circuits. The mass production of hybrids has started. This paper will present the employed quality assurance procedures and report about issues observed so far. Measures to improve the production yield and the current status of the project will be presented.
