Publication number: 20060169113Abstract: 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.Type: ApplicationFiled: March 30, 2006Publication date: August 3, 2006Inventor: Ernest Hamilton

Publication number: 20060162717Abstract: Centering elements may 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. 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.Type: ApplicationFiled: March 14, 2006Publication date: July 27, 2006Inventor: Ernest Hamilton

Publication number: 20050245172Abstract: 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 spacers may be employed to achieve desired spacing of dicing saw blades in the 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.Type: ApplicationFiled: July 8, 2005Publication date: November 3, 2005Inventor: Ernest Hamilton
