VOLUME 18 NO. 1 WIRE BONDING - ASM International

The life and subsequent failure of gold ball bonds on aluminum bond pads by Kirkendall voiding has been well documented. At temperatures above 150 °C for some pack-ages, this can occur quickly and catastrophically. Bonds literally fall off with almost no stress. New 99.9% gold alloy wires (standard gold bonding wire is 99.99% gold)

Ball Milling - an overview | ScienceDirect Topics

Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation. The main factor contributing is the shear force applied by the balls. Using only shear force, one can produce large graphene flakes.
