Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor testing, in particular to a test socket and a sorting machine. Background Art

[0002] The three-temperature sorter needs to use a test seat to assist in temperature control when controlling the high and low temperatures of the chips. The temperature uniformity of the test seat has a significant impact on the internal temperature difference of each chip when multiple chips are tested simultaneously. The better the temperature uniformity of the test seat, the smaller the internal temperature difference of multiple chips tested simultaneously, and the more stable the temperature of the chip test process.

[0003] Figure 1 It is a schematic diagram of the three-dimensional structure when the existing test socket is matched with the equipment panel. The test socket consists of two parts, the lower part is the metal test socket 1, and the upper part is the test socket fixing block 2. After the metal test socket 1 is fixed to the test socket fixing block 2, the test socket fixing block 2 is installed on the equipment panel 3.

[0004] When the sorting machine is performing temperature control, the heating rod inside the metal test seat 1 needs to be heated and temperature controlled.

Therefore, the heating rod cannot heat the side area, resulting in a low temperature in the side area of ​​the heating surface 11 of the metal test seat.

[0005] Therefore, how to provide a test seat and a sorting machine that can effectively alleviate the low temperature of the side area of ​​the heating surface of the metal test seat is one of the technical problems that technical personnel in this field need to solve. Utility Model Content

DETAILED DESCRIPTION

[0034] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0038] The first aspect of the present invention provides a test socket. Figures 4 to 6 As shown, it includes a test seat body 5, a heating rod 6 and an insulation component 7. The lower surface of the test seat body 5 includes a heating surface 522 and a lap surface 511 surrounding the outside of the heating surface 522. The top surface of the insulation component 7 is against the lap surface 511. The heating rod 6 includes a heating part 63 and a non-heating part 61. The heating part 63 is inserted into the test seat body 5 from the side of the test seat body 5. The projection of the non-heating part 61 along the first direction toward the heating surface 522 is located outside the heating surface 522. The projection of the heating part 63 along the first direction toward the heating surface 522 at least partially falls into the heating surface 522. The first direction is perpendicular to the heating surface 522.

[0039] Reference Figure 5 and Figure 6As shown, the test seat in the above embodiment eliminates the test seat fixing block 2 in the prior art, and separates the test seat body 5 from other structures by providing a heat insulation component 7. At the same time, the projection of the non-heating portion 61 along the first direction toward the heating surface 522 is set outside the heating surface 522, and the projection of the heating portion 63 along the first direction toward the heating surface 522 at least partially falls into the heating surface 522. As a result, the side area of ​​the heating surface 522 can be directly opposite to the effective heating area of ​​the heating rod 6 in the height direction, thereby effectively alleviating the low temperature of the side area of ​​the heating surface 522, and the temperature uniformity of the heating surface 522 is better.

[0040] In an alternative embodiment, if Figure 5 As shown, the bottom surface of the heat insulation assembly 7 is higher than the heating surface 522 and is used to abut against the top surface of the panel 9. The above arrangement enables the wiring harness 62 led out of the non-heating part 61 to not be constrained by the panel 9, thereby protecting the wiring harness 62.

[0041] In an optional embodiment, the non-heating portion 61 can be sandwiched between the overlapping surface 511 and the thermal insulation assembly 7, or the non-heating portion 61 is disposed in the test seat body 5 and its projection along the first direction toward the overlapping surface 511 falls into the overlapping surface 511.

[0042] When the non-heating part 61 is arranged in the test seat body 5, the overlapping surface 511 can be completely against the top surface of the insulation component 7, and the heating part 63 and the non-heating part 61 are completely embedded in the test seat body 5. Since the projection of the non-heating part 61 toward the overlapping surface 511 along the first direction falls into the overlapping surface 511, the projection of the non-heating part 61 toward the overlapping surface 511 can be prevented from falling into the heating surface 522, thereby preventing the edge temperature of the heating surface 522 from being too low.

[0043] When the non-heating portion 61 is located between the overlapping surface 511 and the thermal insulation component 7, as shown in FIG. Figure 4 and Figure 7 As shown, in an optional embodiment, the test seat also includes a protection seat 8 sandwiched between the overlapping surface 511 and the thermal insulation component 7, such as Figure 8 As shown, the protection seat 8 has a first passage 81 for the wire harness 62 led out from the outer end of the heating rod 6 to pass through, and the extension direction of the first passage 81 is parallel to the extension direction of the heating rod 6 .

[0044] The first channel 81 in the protective seat 8 provides a sufficient and stable extension space for the wire harness 62 , and can protect the wire harness 62 led out from the heating rod 6 .

[0045] The material of the protection seat 8 can be plastic, metal or rubber, and of course, a material that is not easy to conduct heat and electricity is preferred.

[0046] In an alternative embodiment, if Figure 7As shown, the first passage 81 has a side opening 811 , and the side opening 811 is used for the wire harness 62 to enter the first passage 81 from the side of the protective seat 8 .

[0047] The setting of the above-mentioned side opening 811 facilitates the wiring harness 62 to enter the first channel 81 directly from the side of the protective seat 8 without passing through the end of the first channel 81, which is more convenient for the installation of the heating rod 6 and reduces the damage to the wiring harness 62 during the installation process.

[0048] In an alternative embodiment, if Figure 7 and Fig. 9 As shown, the protection seat 8 also has a second channel 82 connected to the first channel 81, and the second channel 82 is located on the side of the first channel 81. The side of the test seat body 5 is provided with an insertion channel 53 connected to the second channel 82. The second channel 82 and the insertion channel 53 are used to install the temperature sensor.

[0049] In the above embodiment, the temperature sensor can be inserted into the test seat body 5 through the second channel 82 and the insertion channel 53. The protection seat 8 not only protects the heating rod 6, but also limits and protects the temperature sensor.

[0050] It can be understood that the above-mentioned side can be the upper side or the lower side in the vertical direction, or the left side or the right side in the horizontal direction.

[0051] In a preferred embodiment, Figure 7 As shown, the second channel 82 is located to the side of the first channel 81 in the horizontal direction.

[0052] The protection seat 8 can be clamped between the test seat body 5 and the thermal insulation component 7. In order to increase the firmness of the protection seat, the protection seat 8 can also be fixed between the test seat body 5 and the thermal insulation component 7 through a connecting piece.

[0053] In an alternative embodiment, if Figure 7 and Fig. 9 As shown, the protection seat 8 also includes a first through hole 83 spaced apart from the first channel 81 , and a connecting hole 54 communicating with the first through hole 83 is formed on the side of the test seat body 5 . The first through hole 83 and the connecting hole 54 are used to install fasteners.

[0054] When the protection seat 8 needs to be installed, the fastener can be passed through the first through hole 83 and connected to the connecting hole 54 to achieve the connection between the protection seat 8 and the test seat body 5 .

[0055] The fasteners may be screws or pins.

[0056] When the protection seat 8 further includes the second channel 82, the first through hole 83 is spaced apart from the second channel 82. Figure 7As shown, the first through hole 83 may be located at an upper side of the second channel 82 .

[0057] according to Figure 7 The structure of the protection seat 8 is described in detail. In an optional embodiment, the protection seat 8 includes an upper connecting portion 84 and a lower protecting portion 85; the upper connecting portion 84 has a first through hole 83; the outer end of the lower protecting portion 85 has a first channel 81 and a second channel 82, and a side opening 811 is formed between the top and the upper connecting portion 84; the inner end of the lower protecting portion 85 has a notch 851 corresponding to the first channel 81, and the non-heating portion 61 of the heating rod 6 is located at the above-mentioned notch 851.

[0058] In an alternative embodiment, if Figure 7 As shown, the upper connecting portion 84 and the lower protecting portion 85 are of an integrated structure.

[0059] In an alternative embodiment, if Figure 6 As shown, the test seat body 5 includes a lap joint 51 and a lower extension 52 connected to the lap joint 51. The bottom surface of the lap joint 51 has a lap joint surface 511 arranged around the lower extension 52. The bottom surface of the lower extension 52 is a heating surface 522. The lower extension 52 is provided with a working port 521 for cooperating with a supporting seat (not shown) for accommodating the chip. The lap joint 51 and the lower extension 52 adopt an integrated structure. An annular step is protruded inside the working port 521, and the supporting seat is mounted on the step. The chip to be tested is placed on the test seat body 5 through the supporting seat, and then installed on the panel 9 through the test seat body 5, forming a fixed position for testing the chip to be tested as a whole. The test seat body 5 can also provide different temperature test environments for the chip to be tested.

[0060] The above-mentioned test socket body 5 has a simple structure, and the overlapping surface 511 on the bottom of the overlapping part 51 can be overlapped on the insulation component 7 on the top surface of the panel 9, thereby eliminating the test socket fixing block 2. When the heating rod 6 is inserted into the overlapping part 51, the restriction of the insulation component 7 on the wiring harness 62 can be avoided.

[0061] In an alternative embodiment, if Fig.10 As shown, the thermal insulation assembly 7 may include a plurality of thermal insulation strips 71 , which are sequentially arranged around the outer side surface of the lower extension portion 52 , thereby substantially reducing the heat on the overlap portion 51 from being transferred to the panel 9 .

[0062] Of course, adjacent thermal insulation strips 71 may be arranged continuously or at intervals.

[0063] In other embodiments, the thermal insulation assembly 7 may also include only one annular thermal insulation strip, which is disposed around the outer side surface of the lower extension portion 52 .

[0064] The heat insulation strip 71 may be, but is not limited to, a sponge or a rubber strip.

[0065] The embodiment of the second aspect of the utility model is to provide a sorting machine. The sorting machine provided by the embodiment of the second aspect of the utility model includes a panel 9 and the above-mentioned test seat, the thermal insulation component 7 is clamped between the top surface of the panel 9 and the overlapping surface 511, the panel 9 is provided with a second through hole, and the bottom end of the test seat body 5 passes through the second through hole so that the heating surface 522 extends out of the bottom surface of the panel 9.

[0066] The embodiment of the second aspect of the utility model provides a sorting machine including a panel 9 and the above-mentioned test seat. In the above-mentioned sorting machine, the heating rod 6 is arranged higher than the top surface of the panel 9. The panel 9 will not restrict the outlet position of the heating rod 6. At the same time, the side area of ​​the heating surface 522 is opposite to the effective heating area of ​​the heating rod 6 in the height direction, and the temperature uniformity of the test seat is better.

[0067] In an alternative embodiment, if Fig.11 As shown, a wiring board 10 is provided on the panel 9 , and the wiring board 10 is located at one side of the test socket body 5 , and the extension direction of the wiring board 10 is parallel to the extension direction of the heating rod 6 .

[0068] The arrangement of the wiring board 10 facilitates the wiring of the wiring harness 62 and structurally avoids the problem of crushing the wiring harness 62 .

[0069] Specifically, when the heating rods 6 are configured as four heating rods 6 arranged opposite to each other in front and back, two oppositely arranged wiring boards 10 can be provided on the panel 9, one wiring board 10 is used for wiring of the two front heating rods 6, and the other wiring board 10 is used for wiring of the two rear heating rods 6.

[0070] The wiring board 10 may be a wiring sheet metal.
