The cutting of quartz wafer to a certain orientation of the crystal coordinate axis is called the cutting pattern of quartz wafer. Due to the anisotropy of quartz crystal, the electrical and thermal properties of quartz slices are different due to their different elastic properties, piezoelectric properties and temperature properties.
There are two ways to express the cut symbol of quartz crystal, one is the symbol representation prescribed by IRE standard, the other is the custom symbol representation peculiar to quartz crystal. IRE (cut type prescribed by the symbol (XYZlWt) with a set of letters and Angle, said with XYZ three letters in order to represent the chip thickness and length along the axis of the original location, with t (thickness), l (length), W (width) to represent the rotating direction, Angle counterclockwise said plus and minus sign said clockwise.
