Description

test socket

[0001] An example relates to a test socket.

[0002] Generally, most electronic products are formed by assembling multiple electronic components into a single finished product, and manufacturing electronic products in this manner can significantly reduce manufacturing time and production costs.

[0003] To achieve such effects, the electrical reliability of each electronic component constituting the finished electronic product must be tested, and a test socket is required to perform fast and accurate testing of the electronic components.

[0004] Generally, various components such as mobile device camera modules, digital TV parts, and semiconductor chips are tested in test sockets.

[0005] The test socket comprises a base, a mounting block disposed on the base on which a camera module to be tested is mounted, a pin block disposed on the base and connected to the camera module, a pressure block that presses the connector of the camera module onto the pin block, and an actuator that moves the mounting block and the pressure block.

[0006] And the test socket is structured such that testing of the camera module placed on the mounting block is performed by moving the pressure block and the mounting block in the up-and-down direction and / or the forward-and-backward direction.

[0007] However, the location of the connector of the camera module under test varies by model, and consequently, there is a problem in that a test socket with a different structure must be applied depending on the location of the connector of the camera module under test.

[0008] Accordingly, there is a problem in that a separate test socket must be manufactured depending on the model of the camera module to be tested, and thus the setup of the test equipment is required.

[0009] Furthermore, if the model of the camera module under test changes, it is difficult to operate the production facility during the test socket replacement time, which leads to increased losses due to the non-operation of the production facility.

[0010] The embodiment provides a test socket that can be used universally regardless of the model of the test subject.

[0011] In addition, the embodiment provides a test socket that can change the position of the test connector block according to the position of the connector of the camera module to be tested.

[0012] In addition, the embodiment provides a test socket that can change the position of the pressure block according to the position of the connector of the camera module to be tested.

[0013] In addition, the embodiment provides a test connector block that can be connected to the connector of a camera module at multiple locations without positional movement.

[0014] The technical problems to be solved in the embodiments are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0015] A test socket according to an embodiment comprises a base; an actuator disposed on the base; a mounting block disposed on the test board; and a pressure block movably disposed on the mounting block, wherein the mounting block comprises a mounting plate disposed on the actuator and on which a test object is mounted; and a test connector block movably coupled on the mounting plate.

[0016] The embodiment can provide a test socket that can be shared regardless of the product model of the test subject.

[0017] In particular, the embodiment provides a common test board comprising a first group of test pads and a second group of test pads. Additionally, a test connector block is movably coupled to a mounting plate, so as to be electrically connected to the first group of test pads in a first test mode and electrically connected to the second group of test pads in a second test mode. Furthermore, a pressure block may be positioned in an area overlapping with the first group of test pads in a third direction to provide pressure in the first test mode and may be positioned in an area overlapping with the group of test pads in a third direction to provide pressure in the second test mode.

[0018] That is, the embodiment can adjust the coupling position of the test connector block and the pressure block according to the product module of the test subject.

[0019] Therefore, the embodiment has the effect of not requiring the production of separate test sockets for each product model of the test subject.

[0020] Furthermore, by providing a common test socket, the downtime of the production facility can be drastically reduced when the product model of the test target is changed, and the resulting loss due to downtime can be minimized.

[0038] Hereinafter, a test socket according to an embodiment will be described with reference to FIGS. 1 to 13.

[0039] Referring to FIGS. 1 and 2, the test socket includes a base (100), an actuator (200), a test board (300), a seating block (400), and a pressure block (500).

[0040] The base (100) may have a plate shape. The base (100) allows an actuator (200), a test board (300), a seating block (400), and a pressure block (500) to be placed on the upper part.

[0041] In particular, the base (100) may include a base plate (110) and a cylinder (120) coupled to the base plate (110).

[0042] The base plate (110) allows an actuator (200) and a mounting block (400) to be placed on the upper part. Additionally, a cylinder (120) can be coupled to the base plate (110) and coupled to the actuator (200), the mounting block (400), and the pressure block (500).

[0043] At this time, the cylinder (120) may be provided in multiple numbers. For example, the cylinder (120) may include a first cylinder for moving the mounting block (400) in a first direction (e.g., the x-axis direction). Here, the first direction may be expressed as any one of the x-axis direction, the length direction, the front-back direction, and the first horizontal direction.

[0044] Additionally, the cylinder (120) may include a second cylinder for moving the pressure block (500) in a first direction. Additionally, the cylinder (120) may include a third cylinder for moving the pressure block (500) in a third direction (e.g., the z-axis direction). In this case, the third direction may be expressed as any one of the z-axis direction, the up-down direction, and the vertical direction.

[0045] The cylinder (120) may be implemented in a pneumatic manner, but is not limited thereto. The cylinder (120) may have a length in a first direction and / or a length in a third direction. Accordingly, the cylinder (120) can move the seating block (400) in the first direction according to the length that varies in the first direction. Additionally, the cylinder (120) can move the pressure block (500) in the first direction according to the length that varies in the first direction. Additionally, the cylinder (120) can move the pressure block (500) in the third direction according to the length that varies in the third direction.

[0046] An actuator (200) may be placed on the base (100). The actuator (200) can drive a cylinder (120) to move the seating block (400) and / or the pressurizing block (500).

[0047] For example, the actuator (200) may include a first actuator (210) and a second actuator (220).

[0048] Each of the first actuator (200) and the second actuator (220) can drive the cylinder (120).

[0049] For example, the first actuator (210) can drive the first cylinder described above, thereby moving the mounting block (400) in a first direction. For example, the first actuator (210) can move the mounting block (400) in the x-axis direction. Alternatively, the first actuator (210) can move the mounting block (400) in the forward and backward directions. Correspondingly, the first actuator (210) can move the test board (300) together with the mounting block (400) described above.

[0050] For example, the first actuator (210) can move the test board (300) and the mounting block (400) to an initial position before the camera module (600) to be tested is mounted or after the test is completed. For example, the first actuator (210) can move the test board (300) and the mounting block (400) to a first direction (e.g., +x-axis direction) away from the pressure block (500) before the camera module (600) is mounted or after the test is completed. Additionally, the first actuator (210) can move the test board (300) and the mounting block (400) to a test position after the camera module (600) is mounted. For example, the first actuator (210) can move the test board (300) and the mounting block (400) toward the pressure block (500) in a first direction (e.g., -x-axis direction) after the camera module (600) is mounted.

[0051] Additionally, the second actuator (220) can drive the aforementioned second cylinder, thereby moving the pressure block (500) in the first direction, or in the x-axis direction, or in the forward and backward direction. Additionally, the second actuator (220) can drive the aforementioned third cylinder, thereby moving the pressure block (500) in the third direction, or in the z-axis direction, or in the up and down direction.

[0052] For example, the second actuator (220) can move the pressure block (500) to an initial position before the camera module (600) to be tested is mounted or after the test is completed. For example, the second actuator (220) can move the pressure block (500) in a first direction (e.g., -x-axis direction) away from the mounting block (400) before the camera module (600) is mounted or after the test is completed. Additionally, the second actuator (220) can move the pressure block (500) to a test position after the camera module (600) is mounted. For example, the second actuator (220) can move the pressure block (500) in a first direction (e.g., +x-axis direction) toward the mounting block (400) after the camera module (600) is mounted.

[0053] Additionally, the second actuator (220) can move the pressure block (500) away from the mounting block (400) in a third direction (e.g., +z-axis direction) after the test of the camera module (600) to be tested is completed. Additionally, the second actuator (220) can move the pressure block (500) in a third direction (e.g., -z-axis direction) when the test of the camera module (600) is initiated.

[0054] Meanwhile, although it has been described above that the actuator (200) includes a first actuator (210) and a second actuator (220), it is not limited thereto. For example, the actuator (200) may be equipped with only the second actuator (220), and the first actuator (210) may be omitted. In this case, the test board (300) and the mounting block (400) may be fixed in position. In this case, the second actuator (220) can move the pressure block (500) to the position where the mounting block (400) is placed. However, if the pressure block (500) is moved to the position where the mounting block (400) is placed using only the second actuator (220), the distance traveled by the pressure block (500) increases, and the time required for test preparation may increase. Furthermore, if the pressure block (500) is moved to the position where the seating block (400) is placed using only the second actuator (220), the pressure reliability of the pressure block (500) may be reduced, and the test accuracy may be reduced accordingly.

[0055] Accordingly, the embodiment includes a first actuator (210) for moving a seating block (400) and a second actuator (220) for moving a pressure block (500). Accordingly, the embodiment can significantly reduce the test time and improve the test accuracy.

[0056] At this time, although not shown in the drawing, the actuator (200) may include a guide rail. The guide rail may have a bar shape and may be provided on the actuator (200). Additionally, the base (100) may have a guide groove (not shown) corresponding to the guide rail of the actuator (200). Accordingly, the actuator (200) can slide along the guide rail as the guide rail is positioned within the guide groove, and the test board (300), the mounting block (400), and the pressure block (500) can slide accordingly.

[0057] A test board (300) is placed on the actuator (200). Preferably, a test board (300) is placed on the first actuator (210). The test board (300) may be a test circuit board for testing the electrical reliability, operational reliability, and / or physical reliability of the camera module (600) to be tested.

[0058] To this end, the test board (300) may include a plurality of circuit lines electrically connected to the camera module (600) through the mounting block (400). The above-described circuit lines may include a power line that supplies power to the camera module (600), a transmission line that transmits a signal to the camera module (600), and a reception line that receives a signal transmitted from the camera module (600).

[0059] The test board (300) is an integrated board. For example, the test board (300) may be an integrated test board capable of testing all of multiple different camera devices.

[0060] Referring to FIG. 3, the test board (300) may include a test pad (310) that is electrically connected to a camera module (600) through a mounting block (400).

[0061] At this time, the test pad (310) may be divided into multiple groups. For example, the test pad (310) may include a first group of test pads (311) and a second group of test pads (312). At this time, the first group of test pads (311) and the second group of test pads (312) may be placed at different locations on the test board (300).

[0062] For example, the first group of test pads (311) may be provided at a position corresponding to the camera device of the first model on the upper surface of the test board (300), and the second group of test pads (312) may be provided at a position corresponding to the camera device of the second model on the upper surface of the test board (300).

[0063] Preferably, the camera module (600) includes a lens module (610), a flexible circuit board (620) connected to the lens module (610), and a connector (630) disposed on the flexible circuit board (620). In this case, the length or size of the flexible circuit board (620) may differ depending on the product model of the camera module (600), and accordingly, the position of the connector (630) of the camera module (600) may differ depending on the product model. For example, the position of the connector of the camera module of the first product model and the position of the connector of the camera module of the second product model may differ from each other.

[0064] Accordingly, the first group of test pads (311) may be provided at a position corresponding to the connector of the camera module of the first product model on the upper surface of the test board (300). Additionally, the second group of test pads (312) may be provided at a position corresponding to the connector of the camera module of the second product model on the upper surface of the test board (300).

[0065] The mounting block (400) is placed on the first actuator (210). The mounting block (400) is placed on the test board (300).

[0066] Referring to FIGS. 4 to 6, the mounting block (400) may include a mounting plate (410) and a test connector block (420).

[0067] A mounting plate (410) is placed on a test board (300). The mounting plate (410) can provide a space where a camera module (600), which is a test product, can be mounted. For example, the mounting plate (410) may be provided with a mounting portion (411) on which the camera module (600) is mounted. The mounting portion (411) may be a recess provided on the upper surface of the mounting plate (410). The mounting portion (411) may be provided on the upper surface of the mounting plate (410) to correspond to the shape of the camera module (600). At this time, the mounting portion (411) may include a first portion on which the lens module (610) of the camera module (600) is placed, and a second portion on which the flexible circuit board (620) of the camera module (600) is placed.

[0068] The mounting plate (410) may include a first through hole (412). The first through hole (412) may be provided to penetrate the upper and lower surfaces of the mounting plate (410). The first through hole (412) may be provided at a position corresponding to the test pad (310) of the test board (300). For example, the first through hole (412) may be provided in an area that overlaps in a third direction with the test pad (310) of the test board (300) located at the bottom of the mounting block (400). In this case, the first through hole (412) may be provided as a single one. Accordingly, the first through hole (412) may be configured as a single one and overlap in a third direction with each of the first group of test pads (311) and the second group of test pads (312) of the test board (300).

[0069] The mounting plate (410) may be provided with a stepped portion (413, 414). The stepped portion (413, 414) may be provided around the first through hole (412) in the mounting plate (410). For example, the upper surface of the stepped portion (413, 414) may be connected to the inner wall of the first through hole (412).

[0070] The stepped portions (413, 414) may have a step difference from each other and may be provided in multiple numbers.

[0071] For example, the mounting plate (410) may include a first step portion (413) located lower than the upper surface of the mounting plate (410). The first step portion (413) may have a step difference with respect to the upper surface of the mounting plate (410). The mounting plate (410) may further include a second step portion (414) located lower than the first step portion (413). The second step portion (414) may have a step difference with respect to the upper surface of the mounting plate (410) and the first step portion (413), respectively. The second step portion (414) may be provided closer to the inner wall of the first through hole (412) than the first step portion (413). The mounting plate (410) may include a projection portion (415) disposed on the first step portion (413). The projection (415) may protrude in a direction toward the first through hole (412) on the first step portion (413) of the mounting block (400). The projection (415) may overlap the second step portion (414) in a third direction. The projection (415) can improve the fixing force of the test connector block (420) coupled on the second step portion (414). For example, the projection (415) can prevent the test connector block (420) from falling off the mounting plate (410) while the test connector block (420) is coupled on the second step portion (414).

[0072] The mounting plate (410) may be provided with a first coupling hole (416, 417). The first coupling hole (416, 417) may be provided in the second stepped portion (414) of the mounting plate (410).

[0073] The first coupling holes (416, 417) may be spaced apart from each other and provided in multiple numbers on the mounting plate (410).

[0074] For example, the first coupling hole (416, 417) may include a first-1 coupling hole (416) and a first-2 coupling hole (417). The first-1 coupling hole (416) and the first-2 coupling hole (417) may be provided spaced apart from each other in a second direction (e.g., the y-axis direction) on the mounting plate (410). The second direction may be expressed as the y-axis direction, the width direction, and the second horizontal direction, etc.

[0075] The first-1 coupling hole (416) and the first-2 coupling hole (417) may correspond to the test pad (310) of the test board (300). For example, the first-1 coupling hole (417) may correspond to a first group of test pads (311) provided on the test board (300), and the first-2 coupling hole (417) may correspond to a second group of test pads (312) provided on the test board (300).

[0076] The mounting block (400) may include a test connector block (420) that is detachably coupled (or movably coupled) to the mounting plate (410). The test connector block (420) may be screw-coupled to the mounting plate (410), but is not limited thereto.

[0077] The test connector block (420) may include a movable plate (421). The movable plate (421) may be movably coupled to the mounting plate (410). Here, being movably coupled may mean that the coupling position of the movable plate (421) can be changed on the mounting plate (410). For example, the movable plate (421) may be coupled to a first position on the mounting plate (410), and after being separated from the first position, may be coupled to a second position different from the first position.

[0078] The movable plate (421) may include a second coupling hole (422). The second coupling hole (422) may penetrate the upper and lower surfaces of the movable plate (421).

[0079] The second coupling hole (422) may correspond to the first coupling hole (416, 417). For example, the second coupling hole (422) may correspond to the first-1 coupling hole (416) and the first-2 coupling hole (417).

[0080] That is, with the second coupling hole (422) and the first-first coupling hole (416) aligned in the third direction, a coupling member (not shown, e.g., a screw) is inserted into the second coupling hole (422) and the first-first coupling hole (416) so that the movable plate (421) can be coupled onto the mounting plate (410). In this case, the movable plate (421) can be coupled to the first position on the mounting plate (410) where the second coupling hole (422) and the first-first coupling hole (416) are aligned in the third direction.

[0081] Additionally, the movable plate (421) can be separated while in the first position. Also, the movable plate (421) can be coupled to the seating plate (410) by aligning the second coupling hole (422) and the first-second coupling hole (417) in the third direction and then inserting a coupling member. In this case, the movable plate (421) can be coupled to the second position on the seating plate (410) where the second coupling hole (422) and the first-second coupling hole (417) are aligned in the third direction.

[0082] A test connector (423) may be placed on a movable plate (421). The test connector (423) may be fixed on the movable plate (421). The test connector (423) may include a connector pin (423P). The connector pin (423P) may penetrate the test connector (423). For example, the upper end of the connector pin (423P) may be exposed to the upper side of the test connector (423), and the lower end of the connector pin (423P) may be exposed to the lower side of the test connector (423).

[0083] The connector pin (423P) of the test connector (423) can come into contact with the test pad (310) of the test board (300). For example, the connector pin (423P) of the test connector (423) can come into contact with the first group of test pads (311) or the second group of test pads (312).

[0084] For example, when the second coupling hole (422) and the first-1 coupling hole (416) are aligned and the movable plate (421) is coupled to the seating plate (410), the connector pin (423P) of the test connector (423) can come into contact with the first group of test pads (311) of the test board (300).

[0085] Additionally, when the second coupling hole (422) and the first-second coupling hole (417) are aligned and the movable plate (421) is coupled to the mounting plate (410), the connector pin (423P) of the test connector (423) can come into contact with the second group of test pads (312) of the test board (300).

[0086] As described above, the moving plate (421) may be coupled to the first-1 coupling hole (416) or the first-2 coupling hole (417) depending on the model of the camera module (600) to be tested.

[0087] For example, when the camera module of the first model product is mounted on the mounting portion (411) of the mounting plate (410), the movable plate (421) can be coupled to the first-1 coupling hole (416). Through this, the connector of the camera module of the first model product can be coupled to the first group of test pads (311) of the test board (300) through the connector pin (423P) of the test connector (423).

[0088] Additionally, when the camera module of the second model product is mounted on the mounting portion (411) of the mounting plate (410), the movable plate (421) can be coupled to the first-second coupling hole (417). Through this, the connector of the camera module of the second model product can be coupled to the second group of test pads (312) of the test board (300) via the connector pin (423P) of the test connector (423).

[0089] Accordingly, the embodiment can change the position of the moving plate (410) according to the model of the camera module to be tested, thereby enabling testing of different models of camera modules using a single test socket.

[0090] The pressure block (500) is placed on the second actuator (220).

[0091] Referring to FIGS. 7 through 9, the pressure block (500) may include pressure plates (510, 520). The pressure plates (510, 520) may include a first pressure plate (510) and a second pressure plate (520).

[0092] The first pressure plate (510) is placed on the second actuator (220).

[0093] The first pressure plate (510) includes a first fixing hole (511). The first fixing holes (511) may be spaced apart from each other and provided in multiple numbers on the pressure plate (510). The first fixing hole (511) may correspond to the second fixing hole (525) of the second pressure plate (520). For example, the second pressure plate (520) may be fixedly coupled to the first pressure plate (510) by inserting a coupling member (not shown) into the first fixing hole (511) and the second fixing hole (525).

[0094] The first pressure plate (510) may include a second through hole (512). The second through hole (512) may be provided to penetrate the upper and lower surfaces of the second pressure plate (510).

[0095] The second pressure plate (520) can be coupled to the first pressure plate (510).

[0096] The second pressure plate (520) can be detachably coupled to the first pressure plate (510). At this time, the first pressure plate (510) and the second pressure plate (520) may be formed integrally. However, if the first pressure plate (510) and the second pressure plate (520) are formed integrally, stable coupling of the pressure member (530) is difficult, and furthermore, the pressure force using the pressure member (530) may be reduced, and furthermore, it may be difficult to apply to test modules of camera modules of various modules. Therefore, the first pressure plate (510) and the second pressure plate (520) are detachably coupled to each other so that the design of the second pressure plate (520) coupled to the first pressure plate (510) can be changed according to the product to be tested, thereby enabling testing of various products.

[0097] The second pressure plate (520) may be provided with a third coupling hole (416, 417). The third coupling hole (521, 523) may be provided in the second stepped portion (414) of the second pressure plate (520).

[0098] The third coupling holes (521, 523) may be spaced apart from each other and provided in multiple numbers on the second pressure plate (520).

[0099] For example, the third coupling hole (521, 523) may include a third-1 coupling hole (521) and a third-2 coupling hole (523). The third-1 coupling hole (521) and the third-2 coupling hole (523) may be provided spaced apart from each other in a second direction (e.g., the y-axis direction) on the second pressure plate (520).

[0100] The pressure block (500) may include a pressure member (530) that is detachably coupled to the second pressure plate (520). The pressure member (530) may be screw-coupled to the second pressure plate (520), but is not limited thereto.

[0101] The pressure member (530) can be movably coupled to the second pressure plate (520). Here, being movably coupled may mean that the coupling position of the pressure member (530) can be changed on the second pressure plate (520). For example, the pressure member (530) can be coupled to a first position on the second pressure plate (520), and after being separated from the first position, can be coupled to a second position different from the first position.

[0102] The pressure member (530) may include a fourth coupling hole (531). The fourth coupling hole (531) may penetrate the upper and lower surfaces of the pressure member (530).

[0103] The fourth coupling hole (531) may correspond to the third coupling hole (521, 523). For example, the fourth coupling hole (531) may correspond to the third-1 coupling hole (521) and the third-2 coupling hole (523).

[0104] That is, with the fourth coupling hole (531) and the third-1 coupling hole (521) aligned in the third direction, a coupling member (not shown, for example, a screw) is inserted into the fourth coupling hole (531) and the third-1 coupling hole (521) so that the pressing member (530) can be coupled onto the second pressing plate (520). In this case, the pressing member (530) can be coupled to the first position on the second pressing plate (520) where the fourth coupling hole (531) and the third-1 coupling hole (521) are aligned in the third direction.

[0105] Additionally, the pressure member (530) can be separated while in the first position. Also, the pressure member (530) can be coupled to the second pressure plate (520) by aligning the fourth coupling hole (531) and the third-second coupling hole (523) in the third direction and then inserting the coupling member. In this case, the pressure member (530) can be coupled to the second position on the second pressure plate (520) where the fourth coupling hole (531) and the third-second coupling hole (523) are aligned in the third direction.

[0106] Additionally, the second pressure plate (520) may include a first insertion hole (522) and a second insertion hole (524). And, the pressure member (530) may be inserted into either the first insertion hole (522) or the second insertion hole (524).

[0107] For example, the pressure member (530) can be inserted into the first insertion hole (522), and then the coupling member can be inserted into the fourth coupling hole (531) and the third-first coupling hole (521) to be coupled onto the second pressure plate (520).

[0108] Additionally, while the pressure member (530) is inserted into the second insertion hole (524), the coupling member can be inserted into the fourth coupling hole (531) and the third-second coupling hole (522) to be coupled onto the second pressure plate (520).

[0109] At this time, the pressure member (530) may include a protrusion (532) that protrudes downward while inserted into the first insertion hole (522) or the second insertion hole (524). The protrusion (532) may protrude downward with a certain thickness relative to the lower surface of the second pressure plate (520).

[0110] The protrusion (532) can enable the connector (630) of the camera module (600) to be reliably electrically coupled on the test connector block (420). For example, the protrusion (532) can provide downward pressure while positioned on the connector (630) of the camera module (600). By doing so, the protrusion (532) can enable the connector (630) of the camera module (600) to be reliably electrically coupled to the connector pin (423P) of the test connector (423).

[0111] Accordingly, the embodiment can move the position of the moving plate (421) and the position of the pressing member (530) depending on the product to be tested.

[0112] In other words, the operation of the test socket according to the test mode is explained below.

[0113] The embodiment may operate in either a first test mode or a second test mode. Here, the first test mode may refer to a test mode in which a camera module of a first model product is installed, and the second test mode may refer to a test mode in which a camera module of a second model product is installed.

[0114] Referring to FIG. 10(a), in the first test mode, the mounting block (400) and the pressure block (500) can be moved to an initial position before the camera module (600) is mounted on the mounting plate (410) of the mounting block (400). Here, the initial position may mean a position where the test connector block (420) of the mounting block (400) and the pressure member (530) of the pressure block (500) are not aligned with each other in a third direction.

[0115] Subsequently, the embodiment may move the position of the test connector block (420) of the mounting block (400). For example, with the second coupling hole (422) and the first-first coupling hole (416) aligned in a third direction, a coupling member (not shown, e.g., a screw) may be inserted into the second coupling hole (422) and the first-first coupling hole (416) to mount the movable plate (421) onto the mounting plate (410). In this case, the movable plate (421) may be mounted on the mounting plate (410) at a first position where the second coupling hole (422) and the first-first coupling hole (416) are aligned in a third direction. In this case, the connector pin (423P) of the test connector (423) may be electrically contacted with the first group of test pads (311) of the test board (300).

[0116] Additionally, with the fourth coupling hole (531) and the third-1 coupling hole (521) aligned in the third direction, a coupling member (not shown, e.g., a screw) can be inserted into the fourth coupling hole (531) and the third-1 coupling hole (521) to connect the pressing member (530) onto the second pressing plate (520). In this case, the pressing member (530) can be connected to a first position on the second pressing plate (520) where the fourth coupling hole (531) and the third-1 coupling hole (521) are aligned in the third direction.

[0117] Referring to FIG. 10(b), the seating block (400) and the pressure block (500) can be moved to a test position. In this case, the first group of test pads (311) of the test board (300), the connector pins (423P) of the test connector (423), the connector (630) of the camera module, and the pressure member (530) can be aligned in a third direction.

[0118] At this time, the pressure block (500) can move in a first direction toward the seating block (400). At this time, the pressure member (530) can be positioned in a third direction at a certain distance from the first group of test pads (311) of the test board (300), the connector pin (423P) of the test connector (423), and the connector (630) of the camera module.

[0119] Subsequently, with the first group of test pads (311) of the test board (300), the connector pin (423P) of the test connector (423), the connector (630) of the camera module, and the pressure member (530) aligned in a third direction, the pressure block (500) can move in a third direction toward the seating block (400). Through this, the pressure member (530) of the pressure block (500) can provide pressure toward the connector (630) of the camera module (600).

[0120] Referring to FIG. 11 (a), in the second test mode, the mounting block (400) and the pressure block (500) can be moved to an initial position before the camera module (600) is mounted on the mounting plate (410) of the mounting block (400). Here, the initial position may mean a position where the test connector block (420) of the mounting block (400) and the pressure member (530) of the pressure block (500) are not aligned with each other in a third direction.

[0121] Subsequently, the embodiment may move the position of the test connector block (420) of the mounting block (400). For example, with the second coupling hole (422) and the first-second coupling hole (417) aligned in a third direction, a coupling member (not shown, e.g., a screw) may be inserted into the second coupling hole (422) and the first-second coupling hole (416) to mount the movable plate (421) onto the mounting plate (410). In this case, the movable plate (421) may be mounted to a second position on the mounting plate (410) where the second coupling hole (422) and the first-second coupling hole (417) are aligned in a third direction. In this case, the connector pin (423P) of the test connector (423) may be electrically contacted with the second group of test pads (312) of the test board (300).

[0122] Additionally, with the fourth coupling hole (531) and the third-2 coupling hole (523) aligned in the third direction, a coupling member (not shown, e.g., a screw) can be inserted into the fourth coupling hole (531) and the third-2 coupling hole (523) to connect the pressing member (530) onto the second pressing plate (520). In this case, the pressing member (530) can be connected to a first position on the second pressing plate (520) where the fourth coupling hole (531) and the third-2 coupling hole (523) are aligned in the third direction.

[0123] That is, referring to Fig. 11(b), the mounting block (400) and the pressure block (500) can be moved to a test position. In this case, the second group of test pads (312) of the test board (300), the connector pin (423P) of the test connector (423), the connector (630) of the camera module, and the pressure member (530) can be aligned in a third direction.

[0124] At this time, the pressure block (500) can move in a first direction toward the seating block (400). At this time, the pressure member (530) can be positioned in a third direction at a certain distance from the second group of test pads (312) of the test board (300), the connector pin (423P) of the test connector (423), and the connector (630) of the camera module.

[0125] Subsequently, with the test pad (312) of the second group of the test board (300), the connector pin (423P) of the test connector (423), the connector (630) of the camera module, and the pressure member (530) aligned in a third direction, the pressure block (500) can move in a third direction toward the seating block (400). Through this, the pressure member (530) of the pressure block (500) can provide pressure toward the connector (630) of the camera module (600).

[0126] At this time, as shown in FIG. 12, a pressing force may be applied when the pressing member (530), the connector (630) of the camera module (600), the connector pin (423P), and the test pad (310) of the test board (300) are aligned in a third direction.

[0127] Through this, the connector (630) of the camera module (600), the connector pin (423P), and the test pad (310) of the test board (300) can be electrically connected to each other.

[0128]

[0129] A test socket according to a second embodiment is described below. In this case, the structure of the mounting block of the test socket according to the second embodiment may differ from that of the test socket according to the first embodiment. Accordingly, the mounting block of the test socket according to the second embodiment is described below with reference to FIG. 13.

[0130] That is, in the first embodiment, the mounting block (400) is provided with a movable plate (421) on the mounting plate (410), and the mounting position of the movable plate (421) is changed according to the model of the test product. Also, the test connector block (420) includes a connector pin (423P) having a pin type and is fixedly coupled on the movable plate (421).

[0131] Alternatively, the mounting block (1400) according to the second embodiment may include a mounting plate (1410) and a test connector block (1420).

[0132] The mounting plate (1410) is provided with a mounting portion (1411) on which the camera module (600) to be tested is mounted.

[0133] A test board (1300) is placed on the mounting plate (1410). The test board (1300) may have a structure substantially identical to the test board according to the first embodiment, and a detailed description thereof is omitted. The test board (1300) includes a first group of test pads and a second group of test pads.

[0134] A test connector block (1420) is fixedly coupled to the test board (1300). For example, the test connector block (1420) may be a rubber connector. That is, the test connector block (1420) may include a first rubber connector (1421) and a second rubber connector (1422).

[0135] Conductive lines are formed in the first rubber connector (1421) and the second rubber connector (1422), and can be electrically connected to the connector (630) of the camera module (600) through these conductive lines. At this time, since the first rubber connector (1421) and the second rubber connector (1422) are basically formed of a material having elasticity, namely rubber, they can appropriately relieve pressure or load applied to the connector (630).

[0136] At this time, the test connector block (1420) may include a first rubber connector (1421) and a second rubber connector (1422) spaced apart from each other. For example, the first rubber connector (1421) and the second rubber connector (1422) may be spaced apart from each other in a second direction.

[0137] At this time, the first rubber connector (1421) is placed on the first group of test pads of the test board (1300). For example, the first rubber connector (1421) is placed on the first group of test pads of the test board (1300) and can be electrically connected to the first group of test pads.

[0138] Additionally, the second rubber connector (1422) is placed on the second group of test pads of the test board (1300). For example, the second rubber connector (1422) is placed on the second group of test pads of the test board (1300) and can be electrically connected to the second group of test pads.

[0139] At this time, when the first model product is mounted on the mounting plate (1410), the connector of the camera module of the model product is located on the first rubber connector (1421). In this case, the pressure member (530) described in the previous embodiment is placed at the first position, and accordingly, pressure can be applied to the connector of the camera module using the pressure member (530). Through this, the connector of the camera module and the first rubber connector (1421) can be electrically connected.

[0140] Additionally, when a second model product is mounted on the mounting plate (1410), the connector of the camera module of the model product is located on the second rubber connector (1422). In this case, the pressure member (530) described in the previous embodiment is placed at the second position, and accordingly, a pressure can be applied to the connector of the camera module using the pressure member (530). Through this, the connector of the camera module and the second rubber connector (1422) can be electrically connected.
