To withstand the higher particle rates of LHC Runs 2 and 3, with expected luminosities of up to $2\times 10^{34}\,\mathrm{cm^{-2}s^{-1}}$, the current CMS pixel detector at the LHC will be replaced as part of the CMS Phase I Upgrade during the extended winter shutdown in 2016/17. The new pixel detector features a new geometry with one additional detector layer in the barrel region (BPIX) and one pair of additional disks in the forward region (FPIX), new digital readout chips as well as a new CO$_2$-based cooling system for both the barrel and forward region. The BPIX detector module production is summarized, with special focus on the different stages of quality assurance. The quality tests as well as the calibrations which all produced modules undergo in a temperature and humidity controlled environment are described. Exemplarily, the KIT/Aachen production line and its subprocesses are presented together with their quality and yields.
