Generally, crash stops are performed to obtain measurement of charge filling and slurry loading. The crash stop involves running the mill under steady state then cutting off all feed streams to the mill as it is being stopped. Sufficient time is required to obtain all the important measurements correctly during the crash stop. The mill filling should be measured at a minimum of 3 points along t...

Acce Abstract An accelerated optimization method is developed to minimize required time and resources, and demonstrated for a 25 μm diameter Au ball bonding process. After a preparation phase to pre-set many parameters based on literature values, the values for more significant process parameters, impact force (IF) and EFO time (tEFO) for a given target bond geometry are optimized in a second p...
