Thermal map

Thermal map

In order to check the design reliability, a thermal mapping by means of an IR camera was

done. In Figure 20 and 21 the thermal measurements of the board, component side, at

nominal input voltage, are shown. Some pointers, visible in the images, have been placed

across key components or components showing high temperature. The ambient

temperature during both measurements was 27 °C.
