AI Technical Summary

Problems solved by technology

[0006] The above-mentioned technology of using holes to accommodate abrasive particles can only make the abrasive particles be positioned at a specific position, but cannot make the tip of the abrasive particles face upward and have the same amount of protrusion, and cannot use the shape of the hole itself to restrict the abrasive particles. Abrasive particles are hard to turn once positioned

Embodiment Construction

[0028] For other purposes and functions of the present invention, please refer to the drawings and embodiments, and the details are as follows.

[0029] see Figure 1-6 shown. The steering method with regular abrasives of the present invention comprises the following steps:

[0030] (a) On the flat plate 10, 20 respectively make a plurality of positioning units 11, 21 of polygonal cylindrical penetration holes, cylindrical penetration holes or tapered penetration holes, such as figure 1 , 2 , 3, 6 shown;

[0031] (b) Abrasive materials 30 of a plurality of polyhedrons are accommodated in a plurality of positioning units 11, 21 respectively, and a tip 31 of the abrasive material 30 protrudes from the first surfaces 101, 201 of the flat plates 10, 20, and the other of the abrasive material 30 A tip 32 protrudes from the second surface 102, 202 of the flat plate 10, 20 through the positioning unit 11, 21, such as figure 1 , 4 , as shown in 6;

[0032] (c) Fix and combine t...

Abstract

A method and product with regular abrasive steering, which is a positioning unit with a plurality of cylindrical penetration holes or conical penetration holes on the flat plate, and the multiple polyhedral abrasives are automatically dropped into the In multiple positioning units, it is automatically turned so that one tip of the abrasive material protrudes from the first surface of the plate, and the other tip of the abrasive material passes through the positioning unit and protrudes from the second surface of the plate, so it is convenient to place the abrasive material in accordance with the set arrangement pattern , The distance is combined with the flat plate, and the size and shape of the penetration hole of the positioning unit are used to control the exposed height of the tip of the abrasive protruding from the flat plate, and the shape of the positioning unit itself is used to limit the abrasive, so that the abrasive is difficult to rotate after being positioned.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a method for regularly diverting abrasives in a grinding tool and a product thereof. Background technique [0002] All kinds of grinding tools are widely used in the processing of stone, cement, glass, brick, ceramics, metal and other materials. Especially for grinding tools used in wafer manufacturing, in order to obtain better grinding performance of CMP grinding pads, the particle size (Particle size), sharpness, arrangement pattern (Pattern) and spacing ( Pitch) and exposure height (Protrusion height) etc. need to be properly planned and configured. [0003] There are many technologies for regularly arranging or evenly distributing diamond particles and other abrasive particles on the substrate according to a pre-planned plan. For example, Chinese Taiwan patent I286097 discloses a grinding tool and its manufacturing method. The structure of the grinding tool includes a base material, A pl...
