The method of digging was the same in the main as that described by the speaker for the tarantula. The young when they emerge at once build their own miniature nests, which are renewed every spring until they reach(More)
This paper presents a study of the probabilistic effects that act in addition to deterministic (mechanistic) effects to reduce the thermal cycling durability of ball grid array (BGA) interconnects as the component I/O count increases. The mechanistic drivers include increasing thermal expansion mismatch with increasing package size and increasing stress(More)
