The xEPS card<br />
This card is presented in Figure 5.5.<br />
Figure 5.5: The xEPS card developed in collaboration with Thales Alenia Space ETCA<br />
Except for one (situated at the top of the image, on the left), all the components of<br />
this card belong to the SMT category. So, once again, all the components will be modeled<br />
using the global mass smearing method. The P C 104 connector will still be modeled using<br />
the same method that in the previous cases. The properties nally obtained for this card,<br />
are presented in Table 5.5.<br />
Components Young's moduli (GP a) Poisson ratios Densities (kg/m 3 )<br />
P C 104 connector 0.846 0.3 1406.923<br />
PCB 20 0.3 3404.345<br />

The COM card<br />
Unfortunately, at the moment when this thesis ends, this card is not yet manufactured.<br />
So, no picture of it can be presented. In addition, no accurate information are available<br />
for this card (e.g., concerning its mass). Its nal mass was estimated to maximum 65 g by<br />
the COM subsystem. So, like for the other electronic cards, the P C 104 connector will be<br />
model accurately and the mass of the other components will be spread out over the entire<br />
PCB. The properties nally obtained for this card, are presented in Table 5.6.<br />
