Claim 12:
13. A method for testing a chip, comprising:
loading a test circuit board into a device for carrying a chip;
wherein the device for carrying a chip is configured to fasten chips of different sizes and comprises:
a support box, configured to carry the chip; and
a plurality of first elastic snap rings, a first connection terminal of each of the first elastic snap rings being provided on a first inner side wall of the support box, a second connection terminal of each of the first elastic snap rings being suspended and being configured to be in contact with the chip and provide a pressure in a first direction for the chip because an elastic body of each of the first elastic snap rings is in an elastically compressed state, such that the chip is fastened between the second connection terminal and a second inner side wall of the support box opposite to the first inner side wall;
wherein an extension direction of the second connection terminal is parallel to a thickness direction of the chip; an end of the second connection terminal is in contact with a top surface of the test circuit board located on a bottom surface inside the support box; and a length of the second connection terminal along the thickness direction of the chip is greater than or equal to a thickness of the chip; and

wherein the method further comprises:
loading the chip into the device for carrying a chip, and fastening the chip to an upper surface of the test circuit board, wherein the chip is fastened between the second connection terminal of each of the first elastic snap rings and the second inner side wall of the support box; and
controlling the test circuit board to provide a test signal for the chip, to test the chip.
