It has been a week since your original post, but I will reply anyway. All of my experience is in the space industry, but I'm sure other industries use similar type of honeycomb.
An excellent source for sizing honeycomb is Aircraft Design and Analysis by Bruhn. There is a whole chapter in...
Saxon,
I agree, it's a Catch 22. We can't test the boards until we have analysis showing that it will pass the thermal cycling qualification. And we can't do an analysis without good empirical test data.
I do have some empirical data for thermal fatigue of solder. The Engelmaier curves from...
I'm a structures guy, but I've been asked to look at thermal fatigue for a surface mounted transistor. To give you some background, it is company policy not to use surface mounted components on electronics boards. But the electrical guys want to use a specific surface mounted transistor, but...
