The Backward End-Cap (BWEC) of the PANDA Electromagnetic Colorimeter (EMC) will be placed upstream of the interaction point. In this region several other sub-detectors, that operate at different working conditions, are assembled and inserted into PANDA solenoid cavity. This constitutes a challenge for the structural and functional development of the BWEC, since the solid angle coverage with lead tungsten crystals needs to be maximized to meet the physics case requirements. Thanks to a profitable collaboration with the neighbor sub-detector groups, the BWEC 3D design has been constantly updated to take into account the constraints of the experiment. The design of parts, such as the BWEC support, insertion trolley, cooling network and service routing were optimized. In parallel, studies are being done to validate the pressure drop and heat distribution inside the cold volume as well to validate the mechanical stability of the supporting parts.
