For the CMS Phase-2 Outer Tracker upgrade, new silicon strip detector modules consisting of two silicon strip sensors, so-called 2S modules, are developed and produced. This process is distributed along multiple assembly centers worldwide. To ensure consistent module quality, many specifications need to be respected. This includes different kinds of tests and measurement results.

RWTH Aachen University will build around 800 2S modules. The production requires well-organised procedures. To guarantee the transparency and traceability of the production conditions and module quality many data are recorded and analysed.

This talk presents the latest results from the assembly process, with a focus on the quality control measurements that are taken on different test stands. The measurement results are compared with specifications. Details about the data handling with the local and central CMS construction database are given.
