With reference to FIG1 , the present embodiment provides an integrated circuit testing device, which includes an air cavity, a magnetic suction 1, a suction nozzle 5, an air pipe joint 8 and an air inlet valve 9. The side of the air cavity is connected to one end of the air inlet valve 9 by a screw 6, and an air pipe joint 8 is provided at the other end of the air inlet valve 9. It is worth noting that a silicone pad 7 is provided between the side of the air cavity and the end of the air inlet valve 9, so as to further ensure that the connection between the air cavity and the air inlet valve 9 is more solid. Furthermore, a magnetic suction 1 is provided at one end of the air cavity, and the magnetic suction 1 is provided at the end of the external lifting module, and a suction nozzle 5 is provided at the other end of the air cavity, and the suction nozzle 5 is connected to the air inlet hole of the external test product.

In this embodiment, the air cavity includes an air cavity 2, a middle air cavity 3 and a small air cavity 4. The air cavity 2, the middle air cavity 3 and the small air cavity 4 are distributed in sequence from back to front, that is, the air cavity 2 is arranged at the end of the air inlet valve 9, and the magnetic attraction 1 is arranged at one end of the air cavity 2, and the middle air cavity 3 is arranged at the end of the air cavity 2 away from the magnetic attraction 1, and one end of the middle air cavity 3 is connected to one end of the air cavity 2, and the small air cavity 4 is arranged at the other end of the middle air cavity 3, and one end of the small air cavity 4 is connected to the other end of the middle air cavity 3, and the suction nozzle 5 is arranged at the other end of the small air cavity 4.

Furthermore, the interior of the large air cavity 2, the interior of the middle air cavity 3, and the interior of the small air cavity 4 are all hollow, and the interior of the large air cavity 2, the interior of the middle air cavity 3, and the interior of the small air cavity 4 are connected to each other. At the same time, in this embodiment, the material of the suction nozzle 5 can be set to silicone or PU material. At the same time, the suction nozzle 5 can be set to a truncated cone in this embodiment, and the suction nozzle 5 includes an outer circle and an inner circle, wherein the radius of the outer circle is greater than the radius of the inner circle, and the outer circle is set in the end of the small air cavity 4.

In this embodiment, specifically, the integrated circuit testing device in this embodiment inflates the air cavity through the air inlet valve 9, wherein the large air cavity 2 is inflated first, and then the buffered gas inside it is transferred to the inside of the middle air cavity 3, and then the buffered gas is transferred to the inside of the small air cavity 4, and finally the buffered gas is transferred to the suction nozzle 5.

Since the suction nozzle 5 is configured in a truncated cone shape, after the buffered gas is transmitted to the suction nozzle 5, since the suction nozzle 5 is made of silicone or PU material, the seal between the small air cavity 4 and the suction nozzle 5 can be made tighter, thereby ensuring that the gas therebetween does not leak.

That is to say, when the airtightness detector and the tester are started, the airtightness detector inflates the interior of the air cavity through the air inlet valve 9, that is, the chip is inflated through the suction nozzle 5. It can judge the airtightness of the chip by the pressure change inside the chip, thereby avoiding the modification of the Socket (test socket), which not only improves the overall versatility, but also greatly improves the test efficiency.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
