Therefore, they should not be understood as limiting the present invention.

[0020] like Figure 1-Figure 3As shown, a burn-in test mounting seat includes a socket 10 and an elastic member 12 and a pressing platform 20 provided on the socket 10. The pressing platform 20 is elastically connected to the socket 10 through the elastic member 12. The socket 10 includes a seat body 11 and a plurality of clamping members 30. The seat body 11 is provided with a plurality of mounting holes 111 for plugging in the test piece. The plurality of clamping members 30 are all relatively arranged in the mounting holes 111. Figure 7 and Figure 8 As shown, the clamping member 30 is provided with an elastic clamping portion 31, and the clamping portion 31 includes an abutting point 311 for abutting against the pin of the test piece 40. The abutting points 311 on the two opposite clamping members 30 are arranged opposite to each other. The pressing platform 20 includes a mounting plate 21 and a pressing member 22 fixed at the lower end of the mounting plate 21, and the mounting plate 21 includes a plug-in hole 211 opposite to the mounting hole 111; when the pin of the test piece 40 passes through the plug-in hole 211 and the mounting hole 111 and is inserted between the clamping portions 311 of the two opposite clamping members 30, the pin of the test piece 40 is abutted and clamped by the abutting points 311 of the two opposite clamping portions 31. When the mounting plate 21 is pressed again, the pressing member 22 extends into the mounting hole 111 to press the clamping member 30, so that the abutting points 311 on the two opposite clamping portions 31 are separated, and the test piece 40 falls off.

[0021] In the above embodiment, the aging test mount disclosed in the present application includes a plurality of clamping members 30, and the clamping members 30 are provided with elastic clamping portions 31, and the clamping portions 31 include abutment points 311 for abutting against the pins of the test piece 40. When the pins of the test piece 40 are inserted between the clamping portions 31 of two opposing clamping members 30, the test piece 40 (the pins) are abutted and clamped by the abutment points 311 of the two opposing clamping portions 31, thereby realizing the plug-in installation of the test piece. After the test is completed, the mounting plate 21 is pressed again, and the abutment points 311 on the two opposing clamping portions 31 are separated. When the plug-in hole 211 is facing downward, the test piece 40 can be dropped off under the action of gravity.

[0022] The pins of the DUT 40 are always in point contact with the clamp 30, and pressing the mounting plate 21 allows the DUT 40 to be removed by gravity. After testing, there is no need to manually remove the DUT 40, which reduces the area and frequency of friction on the DUT 40, thereby minimizing the impact on the quality of the DUT 40. The number of mounting holes 111 is greater than the number of pins on the DUT. The DUT can be a diode, a transistor, a MOS transistor, a capacitor, or the like.

[0023] In a preferred embodiment, Figure 4As shown, the base 11 further includes a plurality of clamping members 13 for mounting the clamping member 30, a plurality of mounting holes 111 are arranged in parallel, and the clamping members 13 are fixed in the mounting holes 111 one by one. Figure 7-Figure 8 As shown, the clamping member 30 further includes an abutment block 35, a connecting block 33, an elastic rod 32, and a pin 34. The abutment block 35 is fixed to one end of the elastic rod 32, which is disposed below the pressing member 22. The pin 34 is fixed to the other end of the elastic rod 32, and the pin 34 passes through the base 11. The elastic rod 32 is fixedly connected to the pin 34 via the connecting block 33, and the clamping member 30 is clamped to the clamping member 13 via the connecting block 33.

[0024] In the above embodiment, the connecting block 33 and the clamping member 13 can make the clamping member 30 more stable. Because the pins on the device under test 40 are generally arranged in parallel, the multiple mounting holes 111 are arranged in parallel. The abutment block 35 facilitates the pressing member 22 to press the clamping portion 31, causing the clamping portion 31 to separate to the sides, facilitating the separation of the two opposing clamping portions 31. The elastic rod 32 further facilitates the separation of the two opposing clamping portions 31. The clamping member 30 is a metal member, and the pins 34 can be probes, which facilitate the transmission of current or test signals to the device under test 40.

[0025] In a preferred embodiment, Figure 3 As shown, the pressing platform 20 further includes an anti-slip plate 23, which is arranged at the lower end of the mounting plate 21, and a bent end 231 is provided on the anti-slip plate 23. Figure 4-Figure 6 As shown, the side of the base 11 is provided with a slide groove 114 corresponding to the anti-slip plate 23, and the upper end of the slide groove 114 is provided with a stopper 115 corresponding to the bent end 231. The upper end of the base 11 is also provided with a positioning hole 113 and a sleeve hole 112, and the elastic member 12 is disposed in the sleeve hole 112. The pressing platform 20 includes a positioning column 24, one end of which is fixed to the lower end of the mounting plate 21, and the other end of which is disposed in the positioning hole 113. The lower end of the base 11 is also provided with a pinhole 117 and a fixing hole 116 for facilitating fixation. The positioning hole 113 is fixed in the fixing hole 116, and the pin 34 passes through the base 11 through the pinhole 117.

[0026] In the above embodiment, when the mounting plate 21 is pressed, the anti-slip plate 23 slides within the slide groove 114. When the anti-slip plate 23 slides to the upper end of the slide groove 114, the bent end 231 is blocked by the stopper 115, preventing the anti-slip plate 23 from falling off the uppermost end of the slide groove 114. The positioning hole 113 prevents the mounting plate 21 from falling off the base 11, and the sleeve hole 112 prevents the elastic member 12 from falling off. The pinhole 117 facilitates the passage of the pin 34 through the base 11, and the fixing hole 116 facilitates the installation of the base 11 into the test box.

[0027] In a preferred embodiment, Figure 7-Figure 8 As shown, the abutment block 35 is fixedly connected to the elastic rod 32 through the clamping portion 31. The upper end of the abutment block 35 is inclined to the horizontal plane, and the clamping portion is a curved arc with an angle of a degree. The elastic member 12 is a plurality of springs, which are respectively arranged at the four ends of the base body 11. The elastic rod 32 is a spring leaf, wherein 30 0 ≤a≤60 0 The two ends of the abutment block 35 are provided with bending strips 351 , and the angle between the bending strip 351 and the abutment block 35 is smaller than a. The two ends of the pressing member 22 are provided with protrusions corresponding to the bending strip 351 . When the pressing platform 20 is pressed, the protrusions press the bending strip 351 .

[0028] In the above embodiment, in order to facilitate the pressing member 22 to press the abutment block 35, the upper end of the abutment block 35 is inclined to the horizontal plane. The clamping portion is a curved arc piece that facilitates the pins of the test piece to slide into between the two opposite abutment points 311. A plurality of springs are respectively arranged at the four ends of the base 11, which is conducive to the balance of the center of gravity of the pressing platform 20. The bent strip 351 and the protrusion are more conducive to the pressing member 22 pressing the abutment block 35. When the angle between the bent strip 351 and the abutment block 35 is less than a, if the pressing force of the pressing member 22 is too great, the pressing member 22 may slide out of the bent strip 351, thereby preventing the clamping portion 31 from deforming under greater pressure.

[0029] In summary, the aging test mount contacts the workpiece 40 with the clamping portion 30 of the clamping member 30, thereby reducing the contact friction area of ​​the workpiece 40. At the same time, the workpiece 40 can be removed by pressing the pressing platform 20, which can also reduce the number of times the workpiece 40 is rubbed, thereby reducing the impact of the aging test on the quality of the workpiece 40.
