Description

Technical Field

[0001] The present invention relates to a sapphire crystal rod orientation fixing device, and in particular to an adjustable fixing bonding device for sapphire crystal rod orientation measurement. Background Art

[0002] Sapphire is widely used in substrate materials, consumer electronics, military industry and other fields due to its high stability, super-tough mechanical properties, and the wide range of wavelengths that can pass through sapphire crystals.

[0003] The processing process of sapphire wafers is oriented bonding, slicing, grinding, chamfering, cleaning, annealing, waxing, copper polishing, soft polishing, and testing. Oriented sticking is an important process in the production and processing of sapphire wafers, which has a great impact on the wafer yield. Traditional sapphire crystal rod slicing mainly adopts a multi-wire slicer, which uses diamond wire multi-wire cutting technology to cut sapphire crystal rods. At present, before sapphire wafers are processed on the multi-wire cutting machine, they need to be manually glued and oriented to the raw material and the workpiece base through adhesive. Affected by the angle deviation of the multi-wire cutting system wire mesh and the angle deviation of the raw crystal rod, the crystal rod is usually added to the workpiece base after the orientation measurement, and then manually bonded to the workpiece base. Once manually bonded, the crystal rod will slide and deviate before the adhesive solidifies, and the orientation will deviate. After the adhesive solidifies, it will be impossible to correct it, which will directly affect the angle and quality of the wire-cut wafer and is irreversible. Therefore, it is necessary to design a new crystal rod orientation measurement adjustable fixing device to effectively adjust the bonding deviation angle and fix it so that the crystal direction of the processed crystal rod remains parallel to the wire mesh. By adjusting and compensating, the deviation angle can be effectively reduced to maintain cutting accuracy and product yield. Utility Model Content
