i need information about MTBF calculations for PCB connectios.

Q1: do we need to add all nets on PCB to MTBF calculation,

Q2: do we need to add components with their connections(for example a calculation for capacitor and a calculation for capacitor connection)

Q3:stress profile factor for sn29500: how can we consider this parameter for all components. (for example some components are supplied all time but not work all time like bus interfaces )

thank you
