Learning curve resulting from serial flight models production of PLATO focal plane assemblies

The PLATO FPA (Focal Plane Assembly) integration and verification plan is considered to be as an iterative process since the complete spacecraft composed of 26 cameras being the integration of these focal plane assemblies identical with no distinction between FAST and NORMAL cameras. The differences in parts such as CCDs (Charge Coupled Device) and TS (Thermal Strap) between the two types do not affect to the steps followed in the AIV (Assembly, Integration and Verification) procedures. During two years, from 2022 to 2024, INTA qualified personnel has been involved in the integration, assembly, alignment and verification for the FPA Flight Models. This serial production resulted in a learning curve derived from continuous processes improvement and personnel expertise. In this paper will be presented the evolution of AIVT (Assembly, Integration, Verification and Test) activities.
