DETAILED DESCRIPTION

[0038] The application will be further described below in conjunction with the drawings and specific embodiments. The embodiments of the application are given for illustrative and descriptive purposes only, and are not exhaustive or limiting of the application.

The embodiments are chosen and described in order to best explain the principles of the application and its practical application, and to enable others skilled in the art to understand the application for various embodiments with various modifications as are suited to the particular use contemplated.

[0039] Embodiment one, use Figures 1-12 A reliability test device and test method for an integrated circuit of an embodiment of the application are described as follows.

[0040] As Figures 1-2 The application discloses a reliability testing device of integrated circuit, which comprises a support frame 1, support feet 2 fixedly connected to two ends of the support frame 1, a conveyor motor 3 fixedly connected to an outer surface of the support frame 1, a conveying unit 4 fixedly connected to an output end of the conveyor motor 3, test units 5 fixedly connected to a top of the support frame 1, a water tank 10 arranged in a middle part of the support frame 1, a drying unit 6 fixedly connected to a position close to the water tank 10 of the support frame 1, a heating bin 7 fixedly connected to an end of the support frame 1 away from the drying unit 6, a heater 8 fixedly connected to an outer surface of the heating bin 7, and a heat preservation curtain 9 fixedly connected to an inner wall of the heater 8.

[0041] In the working process of the application, first, the integrated circuit board is placed into the conveying unit 4 for movement, the integrated circuit board is heated in the heating bin 7 for a period of time, then the first test unit 5 tests the performance of the integrated circuit board, the integrated circuit board is cooled by the water tank 10 and treated by the drying unit 6, and finally the integrated circuit board is continuously detected by the second test unit 5.

[0042] As Figure 3 The test unit 5 comprises a support plate one 51, a servo motor one 52 fixedly connected to an outer surface of the support plate one 51, a lead screw 53 fixedly connected to an output end of the servo motor one 52, a moving block 54 threadedly connected to an outer surface of the lead screw 53, an extension rod 55 fixedly connected to a bottom of the moving block 54, and a detection mechanism 56 fixedly connected to a bottom of the extension rod 55.

[0043] As Figure 4 The detection mechanism 56 comprises a support plate two 561, a circular hole 562 arranged on the support plate two 561, a power supply block 563 fixedly connected to a top of the support plate two 561, an electric wire 564 fixedly connected to an outer surface of the power supply block 563, an electrification port 565 fixedly connected to a bottom of the electric wire 564, and a pretreatment mechanism 566 fixedly connected to an outer surface of the support plate two 561.

[0044] When the conveying unit 4 drives the integrated circuit board to move to a bottom of the first test unit 5, the conveying unit 4 temporarily stops working, the servo motor one 52 drives the lead screw 53 to rotate, thereby driving the moving block 54 to move transversely and sequentially move to a position directly above the integrated circuit board, then the extension rod 55 moves downward and makes the electrification port 565 contact the power connection end 44 on the integrated circuit board.

[0045] A bottom of the support plate one 51 is fixedly connected to a top of the support frame 1, a top of the support plate two 561 is fixedly connected to a bottom of the extension rod 55, and a top of the electrification port 565 is fixedly connected to a bottom of the support plate two 561.

[0046] As Figure 5As shown, the pre-processing mechanism 566 includes a support rod one 5661, the bottom of the support rod one 5661 is rotatably connected with a rotating rod 5662, the outer surface of the rotating rod 5662 is fixedly connected with a support rod two 5663, one end of the support rod two 5663 away from the rotating rod 5662 is fixedly connected with a protective plate 5664, the bottom of the protective plate 5664 is uniformly provided with a brush 5665, the outer surface of the support rod two 5663 is fixedly connected with a pull rope 5666, one end of the pull rope 5666 away from the support rod two 5663 is fixedly connected with a magnetic block one 5667, the inner wall of the magnetic block one 5667 is slidably connected with a support column 5668.

[0047] Before the power port 565 contacts the power connection end 44 on the integrated circuit board, because the magnetic block one 5667 and the magnetic block two 46 will produce repulsion, as the support plate two 561 moves downward, the magnetic block one 5667 will be pushed upward along the support column 5668 by the repulsive force, accompanied by the pulling of the pull rope 5666, the rotating rod 5662, the support rod two 5663 and the protective plate 5664 will rotate, so that the protective plate 5664 is separated from the power port 565, facilitating subsequent performance testing, and at the same time in the process of rotating the protective plate 5664, the brush 5665 at the bottom will produce brushing with the power connection end 44 on the integrated circuit, so that the dust falling on the surface of the power connection end 44 in the transmission process is scraped off, avoiding that the power port 565 cannot fully contact the power connection end 44 on the integrated circuit board.

[0048] The top of the support rod one 5661 is fixedly connected with the outer surface of the support plate two 561, and the bottom of the support column 5668 is fixedly connected with the top of the support plate two 561.

[0049] As shown in the figure, Figures 6-7 The transmission unit 4 includes a transmission belt 41, the outer surface of the transmission belt 41 is uniformly provided with a placing groove 42, the integrated circuit block 43 is placed on the upper part of the placing groove 42, the power connection end 44 is arranged on the integrated circuit block 43, the rubber clamping block 45 is fixedly connected to the transmission belt 41 near the placing groove 42, the magnetic block two 46 is fixedly connected to the transmission belt 41 near the rubber clamping block 45, and the two ends of the transmission belt 41 are fixedly connected with the rack 47.

[0050] The magnetic block two 46 will generate a gear 683 with the magnetic block one 5667, and the rubber clamping block 45 can ensure that the integrated circuit board does not separate from the transmission belt 41.

[0051] The specific working process is as follows:

[0052] During operation, servo motor 52 drives lead screw 53 to rotate, which in turn moves moving block 54 laterally to the top of the integrated circuit board. Then, telescopic rod 55 moves downward and contacts the power port 565 with the power terminal 44 on the integrated circuit board. As support plate 561 moves downward, magnetic block 5667 is pushed upward along support column 5668 by repulsive force. With the pull of rope 5666, rotating rod 5662, support rod 5663, and protection plate 5664 rotate, causing protection plate 5664 to detach from power port 565 for subsequent performance testing. During the rotation of protection plate 5664, the bottom brush 5665 brushes against the power terminal 44 on the integrated circuit, removing dust that has fallen onto the surface of power terminal 44 during transmission. This ensures that power port 565 makes full contact with the power terminal 44 on the integrated circuit board and allows for reliability testing.

[0053] Example 2, using Figures 1-12 The following describes a reliability testing apparatus and method for an integrated circuit according to an embodiment of the present invention.

[0054] like Figures 8-9 As shown in the figure, the reliability testing device for integrated circuits of the present invention, based on Embodiment 1, includes a drying unit 6 comprising a support plate 3 61, a dryer 62 fixedly connected to the bottom of the support plate 3 61, an air outlet 63 provided at the bottom of the dryer 62, a support rod 3 64 fixedly connected to the outer surface of the dryer 62, an air storage plate 65 fixedly connected to the bottom of the support rod 3 64, air distribution ports 66 symmetrically provided at the bottom of the air storage plate 65, a support plate 4 67 fixedly connected to the bottom of the support plate 3 61, and a wiping mechanism 68 fixedly connected to the outer surface of the support plate 4 67.

[0056] like Figure 10 As shown, the wiping mechanism 68 includes a rotating shaft 681, a sponge block 682 fixedly connected to the outer surface of the rotating shaft 681, a circular block 684 fixedly connected to both ends of the rotating shaft 681, a gear 683 fixedly connected to the rotating shaft 681 near the circular block 684, a track 685 sleeved on the outer surface of the circular block 684, and an air blowing mechanism 686 sleeved on the end of the track 685 away from the circular block 684.

[0057] After the integrated circuit board passes through the water tank 10 for cooling, water will be attached on the integrated circuit board, and the water needs to be completely removed before performance testing. With the movement of the transmission belt 41, the rack 47 drives the gear 683 to rotate, and then drives the shaft 681 to rotate, so that the sponge block 682 wipes the integrated circuit board, and the sponge block 682 can absorb the water on the integrated circuit board, facilitating subsequent performance detection.

[0058] As shown in Figure 11 The blowing mechanism 686 includes a support rod four 6861, the outer surface of the support rod four 6861 is fixedly connected with a round block two 6862, the outer surface of the round block two 6862 is fixedly connected with a fan blade 6863, the outer surface of the gas storage plate 65 is fixedly connected with an air outlet pipe 6865, and the outer surface of the air outlet pipe 6865 is fixedly connected with a wind collecting pipe 6864.

[0059] The rotation of the shaft 681 also drives the round block one 684 to rotate, and then drives the round block two 6862 to rotate through the transmission of the track 685, and drives the fan blade 6863 to rotate, so as to generate wind power. The wind power flows out of the air outlet pipe 6865 through the wind collecting pipe 6864, and then the hot air generated by the dryer 62 flows out of the two gas outlets 66 at the bottom of the gas storage plate 65, so that the hot air dries the power connection end 44 on the integrated circuit board, and the water on the power connection end 44 is quickly dried.

[0060] The bottom of the support plate three 61 is fixedly connected with the top of the support frame 1, the two ends of the shaft 681 are fixedly connected with the outer surface of the support plate four 67, and the outer surface of the round block two 6862 is sleeved with the track 685.

[0063] S2: The heating bin 7 places the integrated circuit in a high-temperature environment for a period of time, and then the test unit 5 detects whether the integrated circuit can work normally and its performance parameters, such as output voltage, current and frequency;

[0064] S3: The transmission unit 4 drives the integrated circuit into the water tank 10 to achieve rapid cooling, and then the integrated circuit is quickly dried after passing through the drying unit 6;

[0065] S4: the test unit 5 will be detected for different temperature environment in the integrated circuit cycle switching again, to observe the performance of the chip in the process of temperature change, the thermal expansion and shrinkage of the packaging material, the reliability of the solder joint.

[0066] The specific workflow is as follows:

[0067] When working, with the movement of the transmission belt 41, the rack 47 will drive the gear 683 to rotate, and then drive the rotating shaft 681 to rotate, so that the sponge block 682 and the integrated circuit board are wiped, and the sponge block 682 will absorb the moisture on the integrated circuit board. At the same time, the rotation of the rotating shaft 681 will also drive the round block one 684 to rotate, and then drive the round block two 6862 to rotate through the transmission of the track 685, and drive the fan blade 6863 to rotate, so as to generate wind power. The wind power will pass through the wind collecting pipe 6864 and flow out from the air outlet pipe 6865, and then the hot air generated by the dryer 62 will flow out from the two air outlet ports 66 at the bottom of the air storage plate 65, so as to dry the power connection end 44 on the integrated circuit board.
