Description

Technology Field

Background Technology

[0002] After the manufacturing process, semiconductor devices undergo testing to evaluate their electrical performance. Performance testing is performed by inserting a test socket, designed to make electrical contact with the device's terminals, between the semiconductor device and a test circuit board. In addition to testing semiconductor devices, test sockets are also used during the burn-in testing process in the manufacturing process.

[0003] When a device under test, such as a semiconductor component, is mounted in a test socket and tested, unreliable contact between the terminals of the device and the contact members of the test socket can lead to reduced signal transmission efficiency. Furthermore, depending on the structure of the contact members, the signal transmission path may become longer, potentially resulting in a decrease in signal transmission speed. Additionally, if the number of terminals on the device exceeds several thousand pins, the high pressure applied to the device during testing may cause physical damage to the chip (die) inside the package, leading to defects.

Specific details for implementing the invention

[0032] Hereinafter, preferred embodiments according to the present invention will be described with reference to the attached drawings. These embodiments are not intended to be limiting.

[0034] 0. Socket equipped with a contact pressure dispersing contact member

[0035] The contact pressure dispersing contact member according to an embodiment of the present invention is a contact pressure dispersing contact member mounted in a socket.

[0036] FIG. 1 shows the structure of a socket in which a contact pressure dispersing contact member (K) according to an embodiment of the present invention can be mounted. The socket in which a contact pressure dispersing contact member (K) according to an embodiment of the present invention can be mounted may include a base (10), an adapter (20), and a cover (30).

[0037] The above base (10) may have a mounting groove (11) in which a contact pressure dispersing contact member (K) can be mounted.

[0038] The above adapter (20) may have a mounting surface on which a device to be tested can be mounted.

[0039] The above cover (30) can be fixed to the upper surface of the base (10). The above cover (30) may have the function of preventing the adapter (20) from detaching and guiding its vertical displacement.

[0040] A predetermined inspection device may be connected to the lower part of a socket on which a contact pressure-dispersing contact member (K) according to an embodiment of the present invention can be mounted. The inspection device may include a predetermined board.

[0041] In addition, when a contact pressure-dispersing contact member (K) is mounted in the socket according to an embodiment of the present invention, a backing plate (50) may be provided to prevent the inspection device from bending or deforming due to the compressive elastic load of the contact member (K), and an insulating sheet (40) may be included for the purpose of electrically blocking the inspection board and the backing plate (50).

[0043] 1. First embodiment

[0044] FIG. 2 is a drawing showing a contact pressure dispersing contact member (K1) according to a first embodiment of the present invention. FIG. 3 is a drawing showing a bottom contact portion (130) and a contact fixing portion (120) of a contact pressure dispersing contact member (K1) according to a first embodiment of the present invention.

[0045] The contact pressure dispersing contact member (K1) according to the first embodiment of the present invention is a contact pressure dispersing contact member mounted in a socket.

[0046] A contact pressure-dispersing contact member (K1) according to the first embodiment of the present invention may include: a top contact portion (110) that contacts a device to be inspected; a contact fixing portion (120) provided below the top contact portion (110); and a bottom contact portion (130) provided below the contact fixing portion (120) that contacts an inspection device.

[0047] Hereinafter, a contact pressure dispersing contact member (K1) according to the first embodiment will be described. For convenience, the contact pressure dispersing contact member (K1) according to the first embodiment will be referred to as the first contact pressure dispersing contact member (100). However, naming it as such does not mean that the contact pressure dispersing contact member (K1) according to the first embodiment must necessarily include other components other than the first contact pressure dispersing contact member (100).

[0049] 1-1. Top contact part (110)

[0050] According to one embodiment, the top contact portion may have an elastic deformation structure in which the width varies in the left-right direction.

[0051] According to a specific embodiment, the top contact portion (110) may include a first top line (111) and a second top line (112). The first top line (111) and the second top line (112) are portions extending upward and are spaced apart from each other by a predetermined distance in the horizontal direction. An upwardly open space portion (113) may be formed between the first top line (111) and the second top line (112).

[0052] According to an embodiment, the first top line (111) and the second top line (112) may have a structure symmetrical with respect to a center line (C) that crosses the center of the contact pressure dispersing contact member in the vertical direction.

[0053] FIG. 4 is a diagram showing the terminal (B) of a device to be tested (T) coming into contact with a contact pressure-dispersing contact member (K1) according to the first embodiment of the present invention.

[0054] Since the first top line (111) and the second top line (112) are elastically deformable and recoverable, the spacing between the first top line (111) and the second top line (112) can be elastically varied. That is, the lateral width of the space portion (113) can be varied.

[0055] Accordingly, as illustrated in FIG. 4, when the terminal (B) of the device under test (T) is inserted between the first top line (111) and the second top line (112) as shown by arrow P, the gap between the first top line (111) and the second top line (112) can be expanded as shown by arrow Q. At this time, the first top line (111) and the second top line (112) exert an elastic restoring force as shown by arrow R, so that the terminal of the device under test can reliably contact the first top line (111) and the second top line (112).

[0056] This is explained in more detail with reference to FIG. 5 as follows. The leading tip portions of the first top line (111) and the second top line (112) come into contact in a tangential direction with the device terminal (Ball) that is the test object. Therefore, the load (P) applied to the device during the test time is decomposed into vector components (Px, Py), thereby inducing a reduction effect of the vertical load.

[0057] According to an embodiment, the top contact portion (110) may include a convergence portion (114). The convergence portion (114) may be a portion where the gap between the first top line (111) and the second top line (112) is narrower than the gap between other portions. For example, the first top line (111) and the second top line (112) may include a fold portion that is folded inwardly to converge. By including the convergence portion (114), elastic deformation and restoration of the first top line (111) and the second top line (112) are promoted, and damage to the terminals of the device under inspection can be prevented.

[0058] Accordingly, the first top line (111) and the second top line (112) are arranged facing each other with the convergence portion (114) as a fixed end, and function as cantilevered elastic bodies that undergo rotational displacement. In addition, the tip portions of the first top line (111) and the second top line (112) come into tangential contact with the device terminal (Ball) of the test object, thereby inducing a reduction effect of the vertical load based on the principle that the load applied to the device during the test is decomposed into vector components.

[0060] 1-2. Contact fixing part (120)

[0061] The above contact fixing part (120) may be a part located between the top contact part (110) and the bottom contact part (130).

[0062] The above contact fixing part (120) may include a plate-shaped middle contact body (122) and a first position fixing projection (124) protruding laterally from the middle contact body (122). By providing the first position fixing projection (124), the first contact pressure dispersing contact member (100) can be position-fixed within the socket.

[0064] 1-3. Bottom contact part (130)

[0065] FIG. 3 is a drawing showing the bottom contact portion (130) and the contact fixing portion (120) of a contact pressure dispersing contact member (K1) according to the first embodiment of the present invention.

[0066] The bottom contact portion (130) includes an elastic deformation portion (133) whose vertical width is variable. The elastic deformation portion (133) is configured to have a variable vertical width. That is, the elastic deformation portion (133) is a part in which the vertical width (M) is reduced when a compressive force is applied in the vertical direction, and the vertical width (M) is restored when the compressive force is released. In other words, since the elastic deformation portion (133) has an elastic restoring force, the reliability of the electrical connection between the device under inspection located on the upper part of the contact pressure-distributing contact member and the inspection device located on the lower part of the contact pressure-distributing contact member can be increased.

[0067] According to an embodiment, the bottom contact portion (130) may include a first bottom portion (131) located at the upper portion and a second bottom portion (132) located at the lower portion. Additionally, the elastic deformation portion (133) is provided between the first bottom portion (131) and the second bottom portion (132), and the elastic deformation portion (133) may connect the first bottom portion (131) and the second bottom portion (132). Accordingly, when the elastic deformation portion (133) is compressed, the distance between the first bottom portion (131) and the second bottom portion (132) is reduced, and when the elastic deformation portion (133) is restored, the distance between the first bottom portion (131) and the second bottom portion (132) may be expanded.

[0068] According to an embodiment, the second bottom part (132) is a bottom tip protruding downward, and the bottom tip may be positioned on a center line (C) that crosses the center of the contact pressure-dispersing contact member in an up-and-down direction, or arranged in a structure symmetrically to the left and right of the center line (C). Accordingly, the bottom tip can make contact with the inspection device without the position of the bottom tip being unintentionally misaligned.

[0069] According to an embodiment, the elastic deformation part (133) may include two or more bottom lines connected in a zigzag shape. The vertical spacing between the bottom lines may be variable. That is, when a compressive force is applied in the vertical direction, the vertical spacing between the bottom lines is reduced, and when the compressive force is released, the vertical width may be restored.

[0070] According to an embodiment, the elastic deformation portion (133) may include a first bottom line (134) and a second bottom line (135). In this case, the first bottom line (134) and the second bottom line (135) have a predetermined distance from each other, but the distance between the first bottom line (134) and the second bottom line (135) may be partially different.

[0071] FIG. 6 is a diagram showing the current path of a contact pressure-dispersing contact member (K1) according to the first embodiment of the present invention.

[0072] According to an embodiment, when a compressive force is applied in the vertical direction, the vertical gap between the first bottom line (134) and the second bottom line (135) is reduced, and contact can be made between at least a part of the first bottom line (134) and at least a part of the second bottom line (135). Accordingly, the length of the current path (V) passing through the contact pressure-dispersing contact member can be reduced. Therefore, it is advantageous for high-frequency signal transmission and high-speed signal transmission, and the signal transmission rate can be improved.

[0073] According to an embodiment, a connecting line (136) connecting the first bottom line (134) and the second bottom line (135) may be further included. The connecting line (136) may have a predetermined curvature and may be a portion connecting the end of the first bottom line (134) and the end of the second bottom line (135) to each other.

[0074] At this time, the gap between the first bottom line (134) and the second bottom line (135) may include a gap between the part spaced apart from the connecting line (136) and the part adjacent to the connecting line (136), where the gap is different from each other. For example, as shown in FIG. 5, the gap of the part spaced apart from the connecting line (136) (T) may be smaller than the gap of the part adjacent to the connecting line (136) where the first bottom line (134) and the second bottom line (135) are connected to each other (S). Therefore, when an upward and downward compressive force is applied, the gap of the part spaced apart from the connecting line (136) (T) is further reduced, and a contact area (V) between the first bottom line (134) and the second bottom line (135) may occur. Accordingly, the length of the current path passing through the contact pressure-dispersing contact member may be reduced. Therefore, it is advantageous for high-frequency and high-speed signal transmission, and the signal transmission rate can be improved.

[0075] According to one embodiment, as illustrated in FIG. 3, a first bottom line (134) is extended along a predetermined first slope line (L1) with a first slope angle (θ1), and a second bottom line (135) is extended along a predetermined second slope line (L2) with a second slope angle (θ2), and the first slope angle (θ1) and the second slope angle (θ2) may have different magnitudes. Accordingly, when an upward and downward compressive force is applied, at least a portion of the first bottom line (134) and the second bottom line (135) may come into contact with each other. Here, the term "slope angle" refers to an angle inclined with respect to a horizontal plane.

[0076] According to the embodiment, by configuring the second inclination angle (θ2) to be larger than the first inclination angle (θ1), the gap of the portion (Q) spaced apart from the connection line (136) may be smaller than the gap of the portion (P) close to the connection line (136) where the first bottom line (134) and the second bottom line (135) are connected to each other. Therefore, when an upward and downward compressive force is applied, the gap of the portion (Q) spaced apart from the connection line (136) is further reduced, and the first bottom line (134) and the second bottom line (135) may come into contact with each other. Consequently, the length of the current path passing through the contact pressure-dispersing contact member may be reduced. Thus, it is advantageous for high-frequency signal transmission and high-speed signal transmission, and the signal transmission rate may be improved.

[0077] Meanwhile, the first bottom line (134) and the second bottom line (135) may be multiple. The angle of inclination of each first bottom line (134) may be the same, but may differ. The angle of inclination of the second bottom line (135) may also be the same, but may differ.

[0079] 2. Second embodiment

[0080] FIG. 7 is a drawing showing a contact pressure dispersing contact member (K2) according to a second embodiment of the present invention. FIG. 8 and 9 are drawings showing the coupling structure of the contact pressure dispersing contact member (K2) according to a second embodiment of the present invention. FIG. 10 is a drawing showing the structure of the second contact segment (200) of the contact pressure dispersing contact member (K2) according to a second embodiment of the present invention.

[0081] A contact pressure-dispersing contact member (K2) according to a second embodiment of the present invention may include a first contact segment (100) comprising a top contact portion (110) that contacts a device under inspection; and a second contact segment (200) coupled to the first contact segment (100).

[0082] The first contact segment (100) above corresponds to the first contact pressure-dispersing contact member (100) described in the first embodiment described above. Accordingly, the description of the first contact pressure-dispersing contact member (100) may correspond to the description of the first contact segment (100). Therefore, redundant descriptions are omitted. In addition, the reference numerals applied to the first contact pressure-dispersing contact member (100) and the reference numerals applied to the first contact segment (100) are referred to identically.

[0083] The second contact segment (200) may include a body portion (210) and a leg portion (220) provided below the body portion (210).

[0085] 2-1. Body part (210)

[0086] The body part (210) is a part provided on the upper part of the leg part (220) and is a part connecting the first leg (221) and the second leg (222) of the leg part (220) described later.

[0087] When the first contact segment (100) and the second contact segment (200) are combined, the body portion (210) is positioned on the contact fixing portion (120) of the first segment and may be positioned between the first top line (111) and the second top line (112) of the top contact portion (110). Additionally, the lower portion of the body portion (210) may come into contact with the upper portion of the contact fixing portion (120). Thus, an electrical signal transmission path may be formed between the first contact segment (100) and the second contact segment (200).

[0089] 2-2. Legbu (220)

[0090] The above leg portion (220) may include a first leg (221), a second leg (222), and a slot (223) located between the first leg (221) and the second leg (222) and open downward.

[0091] The first leg (221) and the second leg (222) constituting the leg portion (220) may have a structure symmetrical with respect to a center line (C) that crosses the center of the second contact segment (200) in an up-and-down direction.

[0092] Referring to FIGS. 8 and 9, the connection between the first contact segment (100) and the second contact segment (200) of the contact pressure dispersing contact member (K2) according to the second embodiment of the present invention is described as follows.

[0093] The first contact segment (100) and the second contact segment (200) can be joined by the first contact segment (100) being inserted upward from the bottom of the second contact segment (200) in the form of an arrow N. At this time, when the first contact segment (100) and the second contact segment (200) are joined together, the joining is performed in such a way that at least one part of the first contact segment (100) is inserted into the slot (223), and at least one part of the first contact segment (100) can be positioned between the first leg (221) and the second leg (222).

[0094] According to a specific embodiment, when the first contact segment (100) and the second contact segment (200) are combined with each other, the body portion (210) of the second contact segment (200) is positioned between the first top line (111) and the second top line (112) of the first contact segment (100), and the contact fixing portion (120) and the bottom contact portion (130) may be positioned within the slot (223).

[0095] At this time, referring to FIGS. 8 and 9, the upper part (bottom surface of the space part (113)) (P) of the contact fixing part (120) of the first contact segment (100) and the bottom surface (upper part of the slot (223)) (Q) of the body part (210) of the second contact segment (200) can come into contact with each other. Thus, the first contact segment (100) and the second contact segment (200) can maintain their positions relative to each other. For example, the second contact segment (200) can act as a HARD STOP that limits the upward movement of the first contact segment (100). Therefore, even if the first position fixing projection (124) described above is not provided on the first contact segment (100), the first contact segment (100) can be fixed in position.

[0097] FIG. 11 is a diagram showing the current path of a contact pressure-dispersing contact member (K2) according to a second embodiment of the present invention.

[0098] Preferably, a contact portion (V) may be formed between the inner surface of the leg portion (220) and the contact fixing portion (120) and the bottom contact portion (130) located within the slot (223). Additionally, a contact portion (V) may be formed between the upper portion of the slot (223) and the contact fixing portion (120) of the first contact segment (100). Thus, an electrical signal transmission path (W) between the first contact segment (100) and the second contact segment (200) may be formed.

[0099] As in the embodiment, by having a configuration in which the first contact segment (100) and the second contact segment (200) are combined with each other, the overall signal transmission path of the contact pressure-dispersing contact member can be shortened. Therefore, it is advantageous for high-frequency signal transmission and high-speed signal transmission, and the signal transmission rate can be improved.

[0100] According to an embodiment, at least one of the first leg (221) and the second leg (222) may include a contact projection (226) protruding inwardly into the slot (223). By providing the contact projection (226), contact between the second contact segment (200) and the contact fixing portion (120) and / or bottom contact portion (130) of the first contact segment (100) can be made more advantageous. Accordingly, contact between the leg portion (220) and the first contact segment (100) can be achieved more reliably, and the formation of a signal transmission path can be promoted.

[0101] According to an embodiment, the leg portion (220) may include a second position fixing projection (225) that protrudes in a horizontal direction.

[0117] 4. Mounting of contact pressure dispersing contact member

[0118] Hereinafter, the mounting of a contact pressure-dispersing contact member according to an embodiment of the present invention will be described.

[0119] FIGS. 16 and 17 show the cross-sectional structure of a socket equipped with a contact pressure dispersing contact member according to an embodiment of the present invention. FIGS. 16 and 17 show a contact pressure dispersing contact member (K3) according to a third embodiment, but a corresponding description can also be applied to the contact pressure dispersing contact member (K1) according to the first and second embodiments.

[0120] The socket is provided with a base (10), and the base (10) may be provided with a mounting groove (11) in which a contact pressure dispersing contact member can be mounted.

[0121] In the housing (11), a stepped portion may be provided in which a position fixing projection provided on a contact pressure dispersing contact member can be caught.

[0122] For example, in the case of a socket in which a contact pressure dispersing contact member (K1) according to the first embodiment can be mounted, it may include a first stepped portion (14) in which a first position fixing projection (124) can be engaged.

[0123] As another example, in the case of a socket in which a contact pressure-dispersing contact member (K3) according to the second and third embodiments can be mounted, it may include a first step portion (14) and a second step portion (15) in which a first position fixing projection (124) of the first contact segment (100) and a second position fixing projection (225) of the second contact segment (200) can be respectively engaged.

[0124] At this time, the mounting groove (11) may include a first mounting space (12) in which a first contact segment (100) can be mounted, and a second mounting space (13) in which a second contact segment (200) can be mounted. The first mounting space (12) and the second mounting space (13) may have a cross-shaped form corresponding to the arrangement of the first contact segment (100) and the second contact segment (200). The first mounting space (12) may have a first stepped portion (14), and the second mounting space (13) may include a second stepped portion (15).

[0125] At this time, the formation of an electrical signal conduction path is made more reliable due to the positional relationship of the connection between the first contact segment (100) and the second contact segment (200). That is, the first contact segment (100) is connected in a manner that is inserted from bottom to top into the slot (223) of the second contact segment (200). Since the first contact segment (100) is provided with a second bottom portion (132) that contacts the inspection device at the bottom and receives an external force from bottom to top, the connection between the first contact segment (100) and the second contact segment (200) is effectively maintained, and an electrical signal conduction path can be reliably formed.
