Problems solved by technology

[0003] However, when breaking ceramic substrates such as alumina, which is harder than glass substrates, the scoring wheel made of cemented carbide and the polycrystalline For the scoring wheel made of diamond sintered body, the front edge of the blade will be chipped or worn immediately, and no cracks will be formed within tens of meters
Therefore, it is practically impossible to use a scribe wheel made of cemented carbide or a sintered polycrystalline diamond to separate ceramic substrates, which are harder than glass substrates.

Embodiment Construction

[0058] Hereinafter, embodiments of the present invention will be described using the drawings. However, the embodiment shown below is merely an example for actualizing the technical idea of ​​the present invention, and there is no intention to limit the present invention to this embodiment. The present invention can of course be applied to other embodiments included in the claims.

[0059] figure 1 It is a schematic diagram of a scribing apparatus 10 according to an embodiment of the present invention. The scribing device 10 includes a mobile station 11 . The moving table 11 is screwed with the ball screw 13, and the ball screw 13 is rotated by the drive of the motor 14, thereby moving in the y-axis direction along the pair of guide rails 12a and 12b.

[0060]A motor 15 is provided on the upper surface of the mobile stand 11 . The motor 15 rotates the upper table 16 in the xy plane and positions it at a predetermined angle. A tempered glass substrate 17 to be scribed is p...

Abstract

To provide a scribing wheel having longer service life than heretofore in decoupling of a ceramic board or the like harder than a glass substrate using the scribing wheel having a blade comprising diamond only, and also to provide a holder unit, a scribing device, a production method for the scribing wheel and a scribing method. There is provided a scribing wheel 40 in which a blade 42 comprises diamond only, and R chamfering of 0.8-5 [mu]m is carried out to a blade tip 43. By using the scribing wheel 40, crack of the blade tip can be reduced to a large extent comparing with the scribing wheelin which the R chamfering is not carried out.

Description

technical field [0001] The present invention relates to a scribe wheel suitable for forming a scribe line on the surface of a brittle material substrate, such as a ceramic substrate, a sapphire substrate, and a silicon substrate, which is harder than a general amorphous glass substrate, and a holder unit provided with the scribe wheel , A marking device, a marking wheel manufacturing method, and a marking method. Background technique [0002] The use of scoring wheel is closely related and inseparable to people. When breaking amorphous glass substrates such as liquid crystal panels, generally speaking, use a scoring wheel made of superhard alloy as disclosed in the patent document "Japanese Utility Laid-Open No. 55-106635", or a wheel made of A scoring wheel made of a polycrystalline diamond (diamond) sintered body that is harder than a superhard alloy. This polycrystalline diamond sintered body is a mixture of diamond particles (75-90 vol%) and a binder (cobalt, etc.) and...
