Equipment 

The experimental part has been done at CSEM Neuchâtel in the Advanced Manufacturing and Components Reliability group. The focus has been given to environmental testing (namely thermal cycling and humidity ingress combined), vibrations testing and mechanical shocks. 
The ESPEC SH-662 (Figure \ref{}) permits to cycles between -60°C to +180°C at maximum ramp-up rates of 2.5°C/min and ramp-down 1.7°C/min . Humidity can be controlled over the range 15°C to 85°C with relative humidity controlled within the bounds depicted in Figure 3. Outside of these bounds the humidity cannot be controlled.
