Figure 5.4: The EPS card This electronic card is the one with the greatest number of components. For the most, these components belong to the SMT category (introduced in section 4.2.5) so, they can be modeled using the global mass smearing method. The P C 104 connector is still modeled using a detailed FE approach. The properties nally obtained for this card are presented in Table 5.4.
