Embodiment 1
[0038]A method for quickly orienting silicon carbide crystals, using an orienting jig before cutting to control the vertical and horizontal movements of the upper platform and the lower platform, respectively, to fix the silicon carbide crystal rods in the vertical and horizontal directions, and realize the carbonization Measurement of the horizontal and vertical angles of silicon crystal rods; a method for rapid orientation of silicon carbide crystals, comprising the following steps:
[0039] S10, stick the silicon carbide ingot on the upper platform of the pre-cutting orienting fixture, and place it for 5 minutes. After the glue is cured, pass the pre-cutting orienting fixture of the bonded silicon carbide ingot through the screw and the pre-cutting orienting fixture The threaded hole is fastened on the X-Ray orientation instrument;
[0040] S20, adjust the adjustment screw on the upper platform to make the upper platform move in the vertical direction, and look for the high...
