Hi Inge,
You know my model for SnPb SJ's--we now have the parameters.
SJ reliability is by definition phenomenological and per forza need to consist of 2 parts: 1) relationship between damage term [however determined] and cyclic life under stated conditions, and 2) a determination of the cyclic damage [by closed form, FEA, etc.].

How can you have a prediction model for the solder alone? You mean solder
plus X,X', X'', Y, Y', Y'' etc??
(I'm in a subordinate state today)?
Seriously...I have been trying to find something too. Most models are so
generalized.?
