Since 2009, CEA have started a long term program to achieve the collective realisation of a large (32x32 pixels) μ-Calorimeters camera for X-ray Astrophysics. This camera is based on silicon doped sensors with Composite Tantalum absorber readout thanks to HEMT/SiGe based Cryo-Electronics. The goal of this development is to achieve a spectral resolution of about 2eV@6keV in a thermal budget of ∼ 1μW@50mK for over 4000 pixels. In the course of this R and D program, we have started a deep system approach and developed various technics to achieve a compact Focal Plane Array (hereafter FPA) design. In this paper, we present most of these technics. Some are dedicated to high impedance sensors such as Silicon doped sensors or High resistivity TES (NbSi HRTES) and other may of much more general use for Astronomical Sub-K spatial instruments. We will present here the status of our development and our FPA integration technics.
