BGA crack initation & growth | 1 February, 2002

Looking for help on getting information on understanding the physics of micro-fracture growth rate within the BGA ball (or solder joints in general). Hoping to find a fairly straight forward study on the concept/theory of this topic. I'm not a metallurgical engineer, so I need things dumbed-down to some degree. Thanks.

�8.4.2, Cracking Of Soldered Joints in the epic "Soldering In Electronics" by RJ Klein Wassink [Electrochemical Publications,ISBN 0 901150 24 X] covers cracking differented by: * Overloading * Creep * Fatigue

You can't go wrong by starting there.
