Methods for designing such a self-avoiding array of abrasive grain and for transferring such an array to an abrasive tool body are described.
9. The abrasive tool of claim 1, wherein the abrasive grain is selected from the group consisting of single abrasive grits, cutting points and composites comprising a plurality of abrasive grits, and combinations thereof. Beskrivning
RELATED APPLICATIONS This application is a Continuation of U.S. application Ser. No. 11/229,408, filed on Sep. 16, 2005, now U.S. Pat. No. 7,507,267 B2, which in turn is a Continuation of U.S. application Ser. No. 10/683,486, filed on Oct. 10, 2003, now abandoned, both of which are incorporated herein by reference in their entirety.
DESCRIPTION OF THE DRAWINGS FIG. 1 is an illustration of a graph of a prior art tool grain distribution corresponding to randomly generated x, y coordinate values and showing irregular distribution along the x and y axes.
Example 1 A CMP pad conditioning tool with self avoiding abrasive grain placement is fabricated by first coating a disk shaped steel substrate (4 inch diameter round plate; 0.3 in thick) with a braze paste. The braze paste contains a brazing filler metal alloy powder (LM Nicrobraz�, obtained from Wall Colmonoy Corporation) and a water-based, fugitive organic binder (Vitta Braze-Gel binder, obtained from Vitta Corporation) consisting of 85% by weight binder and 15% by weight of tripropylene glycol. The braze paste contains 30% by volume binder and 70% by volume metal powder. Braze paste is coated on the disk to a uniform thickness of 0.008 inch, by means of a doctor blade.
