The PANDA experiment will be one of the key projects of the new accelerator facility FAIR in Darmstadt. With its mature detector system it will be able to observe a variety of physical channels. Thus it will make a huge contribution to the understanding of the strong interaction. The electromagnetic process group (EMP) in Mainz is developing the backward end-cap (BWEC) of the electromagnetic calorimeter. For its construction various tests regarding mechanics have been carried out and are foreseen within the R&D framework. A full prototype of the moving supporting system was built and tested, comprising insertion rails and a movable trolley base. The rails were divided in two sections (fixed and removable in PANDA). A big change in the crystal support is being implemented as well and will be validated with a test setup, using FR4 as supporting material. In addition thermal studies using our current proto16 will be carried out.
