[0033] The working method of the present invention is as follows: when in use, the chip body 3 is placed in the fixing frame 2 of the circuit board 1, and then the pins 9 around the chip body 3 are soldered to the circuit board 1. The cover plate 4 is turned over, and when the clamping protrusion 53 is inserted into the clamping slot 52, the clamping protrusion 53 is slidably connected with the first inclined surface 55, and the distance between the clamping protrusions 53 gradually decreases. Then, the second inclined surface 56 of the clamping protrusion 53 is slidably connected with the clamping block 54, and the distance between the clamping protrusions 53 gradually increases until the clamping block 54 slides out of the second inclined surface 56. At this time, the clamping rod 51 and the cover plate 4 are perpendicular to each other, and the clamping protrusion 53 is in contact with the clamping block 54. The waterproof paint 14 is sprayed in the spraying notch 13, between the cover plate 4 and the pins 9 of the chip body 3, and between the fixing frame 2 and the pins 9 of the chip body 3. The waterproof paint 14 flows in the spraying notch 13 to the connection between the notch of the fixing groove 12 and the fixing protrusion 11, completing the encapsulation of the bare chip of the chip body 3. During disassembly, the supporting protrusion 8 is pulled upward with force to move the clamping rod 51 upward, and the second inclined surface 56 of the clamping protrusion 53 is slidably connected with the clamping block 54, and the spacing between the clamping protrusions 53 gradually decreases. Then the clamping protrusion 53 is slidably connected with the first inclined surface 55, and the spacing between the clamping protrusions 53 gradually increases until the clamping rod 51 is separated from the clamping slot 52. The integrated circuit chip and the chip body 3 are convenient for packaging and disassembly of the bare die, and the chip bare die packaging shell has a good fixing effect, which is convenient for efficient packaging of the chip bare die.

[0034] The above is only a preferred embodiment of the present invention.
