Arrhenius activation energy for Copper and tin migration (in

[WayneL]

Hi

In the electronics industry they use the Arrhenius model for reliability
engineering, esp in migration susceptibility.
One of the figure used in the Arrhenius equation is the activation energy.
They tend to use a figure between 0.5eV and 0.9eV, and seems to be based on
empirical data.
Can anyone help me understand where they may have got these figures e.g. is
it the migration susceptibility of say copper or tin ?
Also, where could I ref. the activation energies for different metal?


Regards

Perhaps the Chem Rubber handbook might have a table or data on that or
related values.
