Ozgur,
I don't expect you to get reliable data on the current carrying capacity of
chip bumps or solder balls for two reasons. 1) in many of the bump
technologies in use today, the factor limiting the current is not the size
of the solder connection, it is the interface between the solder and the IC.
2) since the limit is in the interface, it is usually confidential
information.
