Hi

I am using the solid work flow simulation for the thermal anallysis

We had done the simulation for ambient temprature i.e 40 deg centigrade.

The inside temparature of the enclouser was at 69.3deg centigrade.

also the temprature on pcb was 110 degree centirgrade

based on the above result we want to calculate the components ( Electronics ) life.

for calculation the the life of component in the formula mentioned that ambient temprature,but a little confusion,

Which temprature we should considered ?' eighter 40 degree or 69.3 degree or 110 degree?

since component is placed on PCB.

Pelase guide..

ambient temp is 69.3, so not sure why you wouldn't use that

but also if you want to be conservative, use 110

but the important part is what the definition is in your your equation/reference.
