[0002] A bare chip and various types of frames or plastic molding compounds form a chip package. Chip packages come in many different types, generally categorized by the packaging material, the connection method between the chip package and the printed circuit board (PCB), and the package's appearance. Chip packages must be tested before shipment to ensure quality.

[0003] During the testing process of the chip package, its test pins need to be electrically connected to the test circuit. In order to facilitate the fixed connection between the test circuit and the chip package, it is necessary to provide a carrier device that meets the testing requirements of the chip package. The test circuit can provide test electrical signals to the chip package through the test pins of the chip package fixed to the carrier device to test the performance and reliability of the chip package.

[0004] However, different types of chip packages have different dimensions, and the dimensions of the test pins of the same type of chip packages may be different. If matching test carriers are provided for different chip packages, it will obviously cause waste of resources and be detrimental to reducing test costs. Summary of the Invention

[0046] As an example, please refer to Figure 1 、 Figure 2 and Figure 3 By setting a gear 12 on the rotatable vertical rod 10 to surround the gear 11 of the rotatable vertical rod 10, a first through hole 21 and a first sliding groove (which is consistent with the extension direction of the beam 20) are set in the beam 20. Figure 1The top of the first side wall 31 is connected to the first connecting rod 41 located in the first sliding groove, and the top of the second side wall 32 spaced from the first side wall 31 is connected to the second connecting rod 42. The second connecting rod 42 is spaced relative to the first connecting rod 41 and is located in the first sliding groove. The side of the first connecting rod 41 close to the second connecting rod 42 is provided with a plurality of first tooth grooves 411 arranged in a linear manner. The gear 11 rotates by using the mechanical principle that the gear teeth 12 engage with the tooth grooves provided on the body and drive the body to move. The rotatable vertical rod 10 passing through the first through hole 21 in the crossbeam 20 drives the gear 11 on the rotatable vertical rod 10 to rotate, so that the gear teeth 12 of the gear 11 engage with the first tooth groove 411 on the first connecting rod 41, driving the first side wall 31 relatively close to or away from the second side wall 32, adjusting the distance between the first side wall 31 and the second side wall 32, fixing the chip located therebetween, meeting the fixing requirements of chips of different types, shapes and volumes, improving chip testing efficiency while reducing the testing cost of multiple types of chips.

[0047] As an example, please refer to Figure 1 、 Figure 2 and Figure 3 In one embodiment of the present application, the gear 11 is arranged in the middle of the rotatable vertical rod 10; the bottom surface of the rotatable vertical rod 10 is used to contact the top surface of the chip to fix the chip in a direction perpendicular to the top surface of the chip, thereby improving the stability of the chip fixation.

[0048] As an example, please refer to Figure 1 、 Figure 2 and Figure 3 In one embodiment of the present application, an elastic body (not shown) is provided on the bottom surface of the rotatable vertical rod 10. The elastic body is used to elastically contact the top surface of the chip, thereby improving the stability of the chip fixation and avoiding crushing the chip.

[0049] As an example, please refer to Figure 1 、 Figure 2 and Figure 3 In one embodiment of the present application, a handle is provided on the top of the rotatable vertical rod 10 to facilitate rotating the rotatable vertical rod 10 by holding the handle.

[0050] As an example, see Figure 4a and Figure 4bIn one embodiment of the present application, a plurality of second tooth grooves 421 arranged in a linear pattern are provided on the side of the second connecting rod 42 near the first connecting rod 41; wherein, the gear teeth 12 of the gear 11 are also used to engage with the second tooth grooves 421 to drive the second side wall 32 relatively close to or away from the first side wall 31. In this embodiment, by rotating the rotatable vertical rod 10 that passes through the first through hole 21 in the crossbeam 20, the gear 11 on the rotatable vertical rod 10 is driven to rotate, so that the gear teeth 12 of the gear 11 engage with the second tooth grooves 421 on the second connecting rod 42, driving the second side wall 32 relatively close to or away from the first side wall 31, adjusting the distance between the first side wall 31 and the second side wall 32, and fixing the chip located therebetween. This meets the fixing requirements of chips of different types, shapes, and sizes, while improving chip testing efficiency and reducing the testing cost of multiple types of chips.

[0051] As an example, please refer to Figure 4a and Figure 4b In one embodiment of the present application, the first tooth groove 411 and the second tooth groove 421 extend in the same direction. The gear 11 is further configured to rotate between the first tooth groove 411 and the second tooth groove 421, so that the gear teeth 12 of the gear 11 engage with both the first tooth groove 411 and the second tooth groove 421, thereby simultaneously moving the first side wall 31 and the second side wall 32 closer together or further apart. Since the rotation of the rotatable vertical rod 10, which extends through the first through hole 21 in the crossbeam 20, simultaneously drives the first connecting rod 41 and the second connecting rod 42 to move, the efficiency of adjusting the distance between the first side wall 31 and the second side wall 32 is improved.

[0052] As an example, please refer to Figure 4a and Figure 4b In one embodiment of the present application, the surface of the first side wall 31 close to the second side wall 32 is provided with an anti-slip material (not shown); the surface of the second side wall 32 close to the first side wall 31 is provided with an anti-slip material, and the anti-slip material may include anti-slip sand or rubber-plastic anti-slip fiber, etc., which is used to increase the friction between the chip fixed between the first side wall 31 and the second side wall 32 and the first side wall 31 and the second side wall 32, thereby improving the stability of chip fixation.

[0053] As an example, see Figure 5 and Figure 6a In one embodiment of the present application, the chip carrier assembly further includes a third sidewall 33 and a fourth sidewall 34. The top of the third sidewall 33 is connected to the third connecting rod 43. The third connecting rod 43 is connected to the third connecting rod 43 via a second sliding groove ( Figure 5The fourth side wall 34 is spaced apart from the third side wall 33 and is used to fix the chip located therebetween. The top of the fourth side wall 34 is connected to the fourth connecting rod 44. The fourth connecting rod 44 is spaced apart from the third connecting rod 43 and is located in the second slide groove. The side of the third connecting rod 43 close to the fourth connecting rod 44 is provided with a plurality of third tooth grooves 431 arranged in a linear manner. The rotatable vertical rod 10 is used to rotate in the first through hole 21, driving the gear 11 to rotate, so that the gear teeth 12 of the gear 11 engage with the third tooth grooves 431, so as to drive the third side wall 33 to be relatively close to or away from the fourth side wall 34.

[0054] As an example, please refer to Figure 5 and Figure 6a , utilizing the mechanical principle that when the gear 11 rotates, the gear teeth 12 engage with the tooth grooves provided on the main body and drive the movement of the main body. By rotating the rotatable vertical rod 10 that passes through the first through hole 21 in the crossbeam 20, the gear 11 on the rotatable vertical rod 10 is driven to rotate, so that the gear teeth 12 of the gear 11 engage with the third tooth groove 431 on the third connecting rod 43, driving the third side wall 33 relatively close to or away from the fourth side wall 34, adjusting the distance between the third side wall 33 and the fourth side wall 34, and fixing the chip located therebetween, meeting the fixing requirements of chips of different types, shapes and sizes, while improving chip testing efficiency and reducing the testing cost of multiple types of chips.

[0055] As an example, see Figure 5 、 Figure 6b and Figure 6c In one embodiment of the present application, a plurality of fourth tooth grooves 441 arranged in a linear pattern are provided on the side of the fourth connecting rod 44 near the third connecting rod 43; wherein the gear teeth 12 of the gear 11 are also used to engage with the fourth tooth grooves 441 to drive the fourth sidewall 34 relatively closer to or farther away from the third sidewall 33. In this embodiment, by rotating the rotatable vertical rod 10 that passes through the first through hole 21 in the crossbeam 20, the gear 11 on the rotatable vertical rod 10 is driven to rotate, so that the gear teeth 12 of the gear 11 engage with the fourth tooth grooves 441 on the fourth connecting rod 44, driving the fourth sidewall 34 relatively closer to or farther away from the third sidewall 33, adjusting the distance between the third sidewall 33 and the fourth sidewall 34, and fixing the chip located therebetween. This meets the fixing requirements of chips of different types, shapes, and sizes, improving chip testing efficiency while reducing the testing cost of multiple types of chips.

[0056] As an example, see Figure 5 、 Figure 6b and Figure 6cIn one embodiment of the present application, the fourth tooth groove 441 extends in the same direction as the third tooth groove 431. The gear 11 is further configured to rotate between the third tooth groove 431 and the fourth tooth groove 441, so that the gear teeth 12 of the gear 11 engage with both the third tooth groove 431 and the fourth tooth groove 441, thereby simultaneously moving the third side wall 33 and the fourth side wall 34 closer together or farther apart. Since the rotation of the rotatable vertical rod 10, which extends through the first through hole 21 in the crossbeam 20, simultaneously drives the third connecting rod 43 and the fourth connecting rod 44, the efficiency of adjusting the distance between the third side wall 33 and the fourth side wall 34 is improved.

[0057] As an example, see Figure 5 、 Figure 6b 、 Figure 6c and Figure 6d In one embodiment of the present application, the second slide groove 23 is spaced apart from the first slide groove 22, so that the rotatable vertical rod 10 that passes through the first through hole 21 in the beam 20 can be rotated to drive the gear 11 to move from the first slide groove 22 to the second slide groove 23 to adjust the distance between the third side wall 33 and the fourth side wall 34.

[0058] As an example, please refer to Figure 5 、 Figure 6a 、 Figure 6b 、 Figure 6c and Figure 6d In one embodiment of the present application, the extension direction of the second slide groove 23 is oblique to the extension direction of the first slide groove 22, for example, perpendicular, so as to improve the stability of chip fixation.
