Apparatus And Methods For Aligning A Center Of Mass With A Rotational Axis Of A Shaft Or Spindle
US Patent:
7051729, May 30, 2006
Filed:
Dec 21, 2004
Appl. No.:
11/021245
Inventors:
Ernest J. Hamilton - Meridian ID, US
Assignee:
Micron Technology, Inc. - Boise ID
International Classification:
B28D 1/04
US Classification:
125 1301, 125 12, 83665
Abstract:
Centering elements effectively reduce the clearance between a shaft and a rotatable element, such as a blade-fixing flange of a dicing saw for use with semiconductor substrates or carrier substrates. The centering elements may be used to substantially align a center of mass of a rotatable element installed onto the shaft with the axis of rotation of the shaft. The centering element may position the center of mass of a rotatable element at a position that is in substantial alignment with the axis of rotation. Methods for assembling rotatable elements onto shafts and methods for balancing such rotatable elements are also disclosed. Multiple fixtures as well as multiple centering elements may be employed. In addition, one centering element may position more than one fixture.
Dicing Saw Blade Positioning Apparatus And Methods Independent Of Blade Thickness Via Constrained Biasing Elements
US Patent:
7533665, May 19, 2009
Filed:
Jul 8, 2005
Appl. No.:
11/177526
Inventors:
Ernest J. Hamilton - Meridian ID, US
Assignee:
Micron Technology, Inc. - Boise ID
International Classification:
B28D 1/04
US Classification:
125 1301, 83663, 83664
Abstract:
An apparatus for positioning dicing saw blades at a fixed axial distance from one another independent of the thicknesses of the saw blades, where the saw blade thickness varies within a range. Flanges, spacers, and retention elements may be employed to achieve desired spacing of dicing saw blades in an assembly. At least one biasing element that is at least partially constrained about its outer radial periphery may be employed to achieve axial positional independence of each dicing saw blade with respect to other dicing saw blades of the assembly. Further, at least one retention feature may also be used to fix the position of the at least one biasing element in the assembly. Machining techniques may be used to form the components and features of the present invention.

Centering elements may be used to substantially align a center of mass of a rotatable element installed onto the shaft with the axis of rotation of the shaft. Centering element may position the center of mass of a rotatable element at a position that is in substantial alignment with the axis of rotation. Methods for modifying the balance of components of saw assemblies which methods employ the use of centering elements, are also disclosed. Multiple fixtures as well as multiple centering elements may be employed. In addition, one centering element may position more than one fixture.

Method For Using A Blade Assembly Cover
US Patent:
6990880, Jan 31, 2006
Filed:
May 14, 2003
Appl. No.:
10/437252
Inventors:
Ernest J. Hamilton - Meridian ID, US
Assignee:
Micron Technology, Inc. - Boise ID
International Classification:
B26D 7/27
US Classification:
83101, 83168, 451451, 144237, 1442521
Abstract:
A gang blade assembly which controls the trajectory of detritus from a ball grid array substrate dicing operation is described. The assembly includes a cover which partially encases a hub with a plurality of blades. A brush is mounted on the cover to disrupt an air flow created by rotation of the hub and blades. The brush extends beneath the cover and has bristles which contact the hub. The bristles also serve to clear the hub of any detritus produced during dicing. More than one brush may be mounted on the cover.
