Description

[0001] This application is a divisional application with application number CN 202210454222.5, application date April 27, 2022, and invention name “Bracket, plate assembly and aging chamber equipment comprising the bracket and plate assembly”. Technical Field

[0002] The present application relates to a bracket, a plate assembly and an aging chamber device comprising the bracket and the plate assembly. Background Art

[0003] Aging chamber equipment is a device that supports testing electronic components such as semiconductor devices manufactured through a predetermined manufacturing process and classifies the grades of the electronic components according to the test results. Such aging chamber equipment can test electronic components such as semiconductor devices by electrically connecting the electronic components to a tester.

[0004] At the same time, an aging test for reliability verification can be performed on electronic components that are rated as good after electrical inspection using a predetermined inspection device. In such an aging test process, thermal stress and electrical stress are applied to the electronic components to detect defects therein. The electronic components are loaded onto the aging board for the aging test process and placed on the aging board for the test process. In addition, after completing the test process, the electronic components are unloaded from the aging board and classified according to the test results.

[0005] Aging chamber equipment can detect defects in electronic components by applying high-temperature air with the same temperature to the electronic components through aging testing.

[0006] However, since the electronic components in the conventional aging chamber equipment are placed perpendicular to the airflow direction, the air flow in the aging chamber equipment is resisted by the electronic components, so the electronic components generate eddies. Therefore, the conventional aging chamber equipment has the problem of discontinuously generating eddies in the airflow.

[0007] Another problem with conventional aging chamber equipment is that the supplied high-temperature air is not fully applied to the electronic components. For example, when the high-temperature air flows toward the electronic components, it disperses in a direction that deviates from the flow direction, and some air leaks out of the aging chamber equipment. As a result, the amount of high-temperature air applied to the electronic components is insufficient to meet the appropriate target test conditions.

[0008] When performing aging tests on electronic components, accurate aging test results cannot be obtained if these target test conditions are not met. Summary of the invention

[0009] In view of the above circumstances, the present invention provides a aging chamber apparatus that allows high-temperature air supplied to electronic components to be fully applied to the electronic components during a aging test.

[0015] The other side of the guide portion may be configured to move up and down relative to the base portion, and a distance by which the other side of the guide portion descends is smaller than a distance by which the one side of the guide portion descends.

[0016] When the first driving shaft descends, the one side of the guide portion may rotate around the second rotation axis to approach the base, and when the descending first driving shaft ascends, the one side of the guide portion rotates around the second rotation axis to move away from the base.

[0017] The drive shaft may further include a second drive shaft configured to rotate around a rotation axis extending in an up-down direction, and the chamber assembly further includes a bracket holder connected to the second drive shaft and rotates together with the second drive shaft, thereby placing the bracket in a detachable state in which the bracket can be removed from the chamber assembly or in an anti-detachment state in which the bracket mounted to the chamber assembly is prevented from being removed from the chamber assembly.

[0046] The expressions such as upper part and upper surface used herein are described based on the illustrations in the drawings, and it should be noted that they may be replaced by other expressions when the direction of the object changes. The arrangement direction used herein may refer to the longitudinal direction.

[0047] In the following description, one side of the guide portion may be referred to as the rear guide portion, and the other side of the guide portion may be referred to as the front guide portion. In addition, the vertical distance between the front guide portion and the base 500 may be referred to as the first distance h1, and the vertical distance between the rear guide portion and the base 500 may be referred to as the second distance h2.

[0048] Hereinafter, the specific structure of the aging chamber equipment 1 according to the embodiment of the present invention will be described with reference to the accompanying drawings.

[0049] In the following, reference Figure 1 and Figure 2 The aging chamber device 1 according to an embodiment of the present invention can be used for aging tests of electronic components. The aging test described herein is a test in which the electronic component D is not used under normal operating conditions that allow it to achieve its expected life through normal use, but is operated under high temperature conditions to detect early defects that may be generated by the operator during use. The aging chamber device 1 may include a bracket 10, an air supply unit 20, a plate assembly 30, a drive module 40, a chamber assembly 50, and a controller 60.

[0050] Further references Figures 3 to 6 For example, the electronic component D may be a solid state drive (SSD) having a certain thickness and a certain width. The thickness of the electronic component D is defined as the length of the electronic component D extending in the left-right direction. Similarly, the width of the electronic component D is defined as the length of the electronic component D extending in the front-back direction. The width of the electronic component D may be greater than the thickness of the electronic component D. The electronic component D may have a plate shape in which the areas of the front and rear surfaces are narrower than the areas of the left and right side surfaces.

[0051] The bracket 10 may support one or more plate assemblies 30. The bracket 10 may be detachably mounted to the chamber assembly 50. For example, the bracket 10 may be moved backward and mounted to the chamber assembly 50, or the bracket 10 mounted on the chamber assembly 50 may be moved forward relative to the chamber assembly 50 to be removed from the chamber assembly 50. In addition, the bracket 10 may include a plurality of brackets 10. The plurality of brackets 10 may be arranged vertically. In addition, the plurality of brackets 10 may be individually mounted to or removed from the chamber assembly 50. The bracket 10 may include a support frame 100, a lifting unit 200, a roller 300, and an extension unit 400.

[0052] The support frame 100 may support the plate assembly 30, the lifting unit 200, the roller 300, and the extension unit 400. The support frame 100 may include a horizontal support frame 110 and a vertical support frame 120. The horizontal support frame 110 may be a frame extending horizontally. For example, the horizontal support frame 110 may be a plurality of frames extending in the front-rear direction and the left-right direction. The horizontal support frame 110 may be connected to the upper end and the lower end of the vertical support frame 120.

[0053] The vertical support frame 120 may be a frame extending in the up-down direction. The vertical support frame 120 may be a plurality of frames extending in the up-down direction from the points where the corners of the horizontal support frame 110 intersect. The vertical support frame 120 may include a guide rail extending in the up-down direction to guide the lifting unit 200 to rise and fall.

[0054] Reference again Figure 4 and Figure 5 , the lifting unit 200 can move in the up and down directions. For example, the lifting unit 200 can move vertically along the guide rail. The lifting unit 200 can selectively apply pressure to the guide portion 600 described below. Through the lifting unit 200, the guide portion 600 can rotate around the base 500 described below. A plurality of lifting units 200 can be provided. For example, a plurality of lifting units 200 can be placed near the left and right sides of the plate assembly 30. The lifting unit 200 can have a wire support protrusion 200a and a capture support protrusion 200b.

[0055] The wire support protrusion 200a can support the wire 420 described below. The wire support protrusion 200a can have a wire groove, and the wire 420 is captured in the wire groove. The wire groove can be an annular groove with a central axis extending in the front-to-back direction. The wire support protrusion 200a can have a shape protruding toward the plate assembly 30. For example, the wire support protrusion 200a of the lifting unit 200 placed adjacent to the right side of the plate assembly 30 can protrude to the left. Similarly, the wire support protrusion 200a of the lifting unit 200 placed adjacent to the left side of the plate assembly 30 can protrude to the right.

[0056] The capture support protrusion 200b may selectively support the capture portion 53 described below. The capture support protrusion 200b may support the capture portion 53 while being in contact with the capture portion 53. In other words, when the capture support protrusion 200b is not in contact with the capture portion 53, the capture portion 53 may not be supported by the capture support protrusion 200b. The capture support protrusion 200b may protrude toward the plate assembly 30. For example, the capture support protrusion 200b of the lifting unit 200 placed adjacent to the right side of the plate assembly 30 may protrude to the left. Similarly, the capture support protrusion 200b of the lifting unit 200 placed adjacent to the left side of the plate assembly 30 may protrude to the right.

[0057] When the wire 420 moves, the roller 300 can reduce the friction force applied to the wire 420. When the wire 420 moves, the roller 300 can guide the movement of the wire 420 while contacting the wire 420. The roller 300 can be configured to rotate while contacting the wire 420. For example, the roller 300 can have a roller groove 300a, the wire 420 is captured in the roller groove 300a, and the roller 300 can rotate while the wire 420 is in contact with the roller groove 300a. The roller groove 300a can be an annular groove whose central axis extends in the left and right directions. The central axis of the roller groove 300a and the central axis of the wire groove can extend in different directions so that they deviate from each other. The roller 300 can rotate around a rotation axis extending in the left and right directions. The roller 300 can be connected to the horizontal support frame 110. The roller 300 may include a plurality of rollers 300. The plurality of rollers 300 can be arranged to be spaced apart from each other in the left and right directions. For example, multiple rollers 300 can be connected between the horizontal support frame 110 extending in the left-right direction at the rear side and the horizontal support frame 110 extending in the front-to-back direction at the left side, and between the horizontal support frame 110 extending in the left-right direction at the rear side and the horizontal support frame 110 extending in the front-to-back direction at the right side.

[0058] The extension unit 400 may extend or contract as the lifting unit 200 rises or falls. For example, the extension unit 400 may extend as the lifting unit 200 falls. Therefore, the extension unit 400 may provide an upward restoring force to the lifting unit 200. In addition, the extension unit 400 may contract as the lifting unit 200 rises. Therefore, the extension unit 400 may provide an upward restoring force to the lifting unit 200. The extension unit 400 may include an elastic member 410, a wire 420, and a support plate 430.

[0059] The elastic member 410 can provide a restoring force for the wire 420. For example, when the wire 420 moves away from the elastic member 410, the elastic member 410 can provide a restoring force to the wire 420, so as to be closer to the elastic member 410. An example of the elastic member 410 can be a compression coil spring. One end of the elastic member 410 can be fixed to the front of the support plate 430, and the other end thereof can be moved relative to the support plate 430. In other words, one end of the elastic member 410 can be a fixed end, and the other end of the elastic member 410 can be a free end, and its movement is not restricted. The wire 420 can be connected to the other end of the elastic member 410. For example, a plurality of holes for supporting two wires 420 can be formed at the other end of the elastic member 410. The elastic member 410 can extend in the front-back direction.

[0060] The wire 420 may extend between the other end of the elastic member 410 and the wire support protrusion 200a. For example, the wire 420 may apply a backward pressure to the other end of the elastic member 410 and an upward pressure to the wire support protrusion 200a, and at the same time, the wire 420 is tightened between the other end of the elastic member 410 and the wire support protrusion 200a. The wire 420 may be inserted into the roller groove 300a and move while contacting the roller 300.

[0061] The support plate 430 may fix and support one end of the elastic member 410. The support plate 430 may be supported by the horizontal support frame 110 disposed at an upper side of the plurality of horizontal support frames 110. The support plate 430 may have a plate shape extending in a horizontal direction.

[0062] Reference again Figure 2 , the air supply unit 20 can supply fluid to one or more board assemblies 30 or cause fluid to flow out of one or more board assemblies 30. The air supply unit 20 can cause the fluid to flow from the front to the rear. The fluid moved by the air supply unit 20 can be perpendicular to the front surface and the rear surface of the electronic component D. In other words, the fluid moved by the air supply unit 20 can be guided from the front to the rear, and can be perpendicular to an imaginary straight line extending in the left and right directions between the left and right surfaces of the board assembly 30. In addition, the fluid moved by the air supply unit 20 can be perpendicular to the direction in which the bracket 10 is accommodated in the chamber frame 51. The air supply unit 20 may include an inlet air supply unit 20a and an outlet air supply unit 20b, which are respectively arranged at the front and rear sides, and are spaced a predetermined distance from the bracket 10.

[0063] The inlet air supply portion 20a can introduce the fluid into the board assembly 30 along the arrangement direction toward the electronic components D. For example, the inlet air supply portion 20a can be spaced apart from the bracket 10 in front of the bracket 10. The outlet air supply portion 20b can make the fluid flow out from the board assembly 30 along the arrangement direction. For example, the outlet air supply portion 20b can be spaced apart from the bracket 10 at the back of the bracket 10. The inlet air supply portion 20a and the outlet air supply portion 20b can be configured in the same manner or in different manners. For example, the inlet air supply portion 20a and the outlet air supply portion 20b can both include a blower, a blower bracket, and a duct.

[0064] The blower can make the fluid flow from front to back. The blower may include a plurality of blowers. For example, a plurality of blowers may be arranged in the up-down direction. However, the concept of the present invention is not necessarily limited thereto, and the blower may be arranged above a plurality of plate assemblies 30. In addition, the blower may be arranged above a plurality of plate assemblies 30 and supply the fluid to the pipeline.

[0065] The blower bracket may support a plurality of blowers. The blower bracket may extend in an up-down direction. A plurality of blowers may be fixedly disposed in the blower bracket. The duct may draw fluid from the blowers and supply the fluid to a plurality of plate assemblies 30. The duct may provide a flow path through which the fluid supplied from the blowers flows to the plate assemblies 30. In other words, the duct may guide the fluid supplied from the blowers to be supplied to the plate assemblies 30.

[0066] The board assembly 30 may provide a space for placing a plurality of electronic components D, and may fix and support the placed electronic components D. In addition, the board assembly 30 may move while supporting the plurality of electronic components D. The board assembly 30 may include a base 500 , a guide portion 600 , a board frame 700 , hinge portions 810 and 820 , and an air guide plate 900 .

[0067] The base 500 may provide a component for arranging the electronic components D. A plurality of electronic components D may be arranged horizontally in a grid pattern on the base 500. For example, a plurality of electronic components D may be arranged on the base 500 so that their front and rear surfaces face left and right. In other words, the fluid sucked into the board assembly 30 may flow parallel to the front and rear surfaces of the electronic components D. The base 500 may include a plurality of sockets 510 and a substrate 520 supporting the plurality of sockets 510.

[0068] The socket 510 may be configured in such a manner that the electronic component D is inserted in a vertical direction (i.e., an upright position). In other words, the electronic component D may be inserted into the socket 510 in a direction in which the electronic component D extends relatively long (the up-and-down direction described in the present invention). In addition, a plurality of sockets 510 may be provided to accommodate a plurality of electronic components D therein. The plurality of sockets 510 may be arranged in a grid pattern in the front-to-back direction and the left-to-right direction.

[0069] Further references Figure 7 , among the plurality of sockets 510, the electronic component D may not be placed in at least some of the sockets 510 arranged in the center between the front and rear sides of the plurality of sockets 510. In other words, the electronic component D may not be placed in one or more rows of sockets 510 arranged in the left-right direction at the center of the plurality of sockets 510. The unplaced state of the electronic component D can be confirmed by the perforation 900a described below. For example, the placement state of the electronic component D can be confirmed by the naked eye of the operator through the perforation 900a, or can be detected by the height sensor described below. In this way, the placement state of the electronic component D can be confirmed by the perforation 900a. When the electronic component D is not placed in one or more rows of sockets 510 arranged in the left-right direction at the center of the plurality of sockets 510, it is possible to prevent the generation of eddy currents due to the interruption of the fluid flow in the fluid flow space S, or the uneven temperature of the fluid when the fluid stagnates in the fluid flow space S.

[0070] The substrate 520 may be a PCB substrate that allows a plurality of electronic components D disposed in the socket 510 to be electrically connected to each other. A plurality of sockets 510 may be disposed on an upper surface of the substrate 520. The substrate 520 may extend in the front-rear direction and the left-right direction.

[0071] Further references Figures 8 to 11 , the guide portion 600 may guide the movement of the fluid in the fluid movement space S. The fluid movement space S may be a space between the base 500 and the guide portion 600. The guide portion 600 may guide the movement of the fluid in the upper side of each plate assembly 30. The guide portion 600 may extend in the front-rear direction and the left-right direction. For example, the guide portion 600 may be formed by a member having a shape that overlaps with a plurality of sockets 510 provided in the base 500 when protruding downward toward the base 500 adjacent to the lower side.

[0072] The guide portion 600 may be spaced apart upward from the base portion 500. The guide portion 600 may be configured to be raised or lowered by the driving module 40. The guide portion 600 may be configured such that the first distance h1 is equal to or different from the second distance h2. For example, at least one of the front guide portion 610 and the second guide portion 620 may be raised or lowered such that the first distance h1 is equal to or different from the second distance h2.

[0073] In addition, the guide 600 can be connected by a predetermined rotation axis to rotate around the predetermined rotation axis so that the first distance h1 is equal to or different from the second distance h2. For example, the guide 600 can be configured to rotate around the predetermined rotation axis relative to the bracket 10 so that the first distance h1 is equal to or different from the second distance h2.

[0074] The guide portion 600 may be supported by the bracket 10. The guide portion 600 may be rotatably connected to the bracket 10. For example, the front guide portion 610 may be connected to the front side of the bracket 10 to rotate around a predetermined rotation axis relative to the bracket 10. For example, the guide portion 600 may rotate around a predetermined rotation axis so that one side of the guide portion 600 is away from or close to the base 500. Here, the predetermined rotation axis extends in the left-right direction and may be provided in the front guide portion 610 or the rear guide portion 620. For example, the predetermined rotation axis may be included in a front hinge portion 810 connected to the front guide portion 610 or a rear hinge portion 820 connected to the rear guide portion 620.

[0075] The guide portion 600 may include a front guide portion 610 and a rear guide portion 620. In other words, the front guide portion 610 refers to the front side (the other side) of the guide portion 600, and the rear guide portion 620 refers to the rear side (one side) of the guide portion 600.

[0076] The front guide 610 may be disposed to be spaced a predetermined distance from the upper surface of the base 500. The front guide 610 may include a hinge catching portion that may be caught on the rotation axis of the front hinge portion 810. The hinge catching portion may protrude forward from the left and right sides of the front guide 610. In addition, the hinge catching portion may have a shape of a hook that may be caught on the rotation axis of the front hinge portion 810. The front guide 610 may be connected to the upper side and the front side of one of the bracket 10, the chamber assembly 50, and the plate frame 700 through the front hinge portion 810.

[0077] The rear guide 620 can guide the movement of the fluid flowing out of the fluid moving space S. In addition, the rear guide 620 can be raised or lowered by the driving module 40. The rear guide 620 can move in the up and down directions. For example, when the capture support protrusion 200b is pressed downward, the rear guide 620 can be lowered. In addition, when the pressure applied to the capture support protrusion 200b is released, the rear guide 620 can rise. The rear guide 620 can be rotatably connected to the lifting unit 200. For example, the rear guide 620 can be configured to rotate around a rotation axis provided by the lifting unit 200.

[0078] The rear guide portion 620 may be configured to rotate around the rotation axis of the rear hinge portion 820. For example, when the capture support protrusion 200b is pressed downward, the rear guide portion 620 may rotate around the rotation axis of the rear hinge portion 820 to get closer to the base 500. In addition, the pressure applied to the capture support protrusion 200b is released, and the rear guide portion 600 may rotate around the rotation axis of the rear hinge portion 820 to get away from the base 500. The rotation axis provided by the lifting unit 200 may be, for example, an imaginary straight line extending in the left-right direction perpendicular to the up-down direction and the front-rear direction.

[0079] If no external force is applied to the rear guide 620, the rear guide 620 may be supported by the wire 420 to be disposed at the upper and rear sides of the board assembly 30. The rear guide 620 may have a shape in which a portion (eg, left and right sides) further extends rearward.

[0080] The second distance h2 for the rear guide portion 620 may be adjusted to the height of the electronic component D. For example, in the case where the electronic component D is replaced with an electronic component D having a shorter height, the rear guide portion 620 may be lowered so that the guide portion 600 is spaced a predetermined distance from the top of the electronic component D. For another example, when the electronic component D is replaced with an electronic component D having a higher height, the rear guide portion 620 may be raised so that the guide portion 600 is spaced a predetermined distance from the top of the electronic component D.

[0081] However, the concept of the present invention is not necessarily limited to this, and further reference is made to Figures 12 to 15 , the front guide portion 610 may be configured to rise or fall. For example, at least one of the front guide portion 610 and the rear guide portion 620 may rise or fall to adjust the distance between the first distance h1 and the second distance h2. In this case, the front guide portion 610 may rise or fall while in contact with the auxiliary capture portion 54. In addition, the front guide portion 610 may rise or fall by the rotation of the guide portion 600.

[0082] The plate frame 700 may support the base 500. In addition, the plate frame 700 may be connected to the upper surface of the base 500. The plate frame 700 may include a horizontal plate frame 710 and a vertical plate frame 720.

[0083] The horizontal plate frame 710 may protect the electronic components D arranged on the base 500 from external influences of the board assembly 30. The horizontal plate frame 710 may extend horizontally along the edge of the base 500. For example, the horizontal plate frame 710 may extend in the front-rear direction and the left-right direction. In addition, the horizontal plate frame 710 may be connected to the vertical plate frame 720. The horizontal plate frame 710 may include a lower horizontal plate frame and an upper horizontal plate frame.

[0084] The vertical plate frame 720 can protect the electronic components D arranged on the base 500 from the external influence of the board assembly 30. The vertical plate frame 720 can extend from the upper surface of the base 500 toward the horizontal plate frame 710 in the up-down direction. A plurality of vertical plate frames 720 can be provided. The vertical plate frames 720 can be spaced apart to correspond to the left and right lengths of the rear guide 620 of the rear side. For example, a plurality of vertical plate frames 720 can be spaced apart at the rear side of the base 500 along the left-right direction. More specifically, two vertical plate frames 720 can be arranged on the left side of the rear of the base 500, and another two vertical plate frames 720 can be arranged on the right side of the rear of the base 500. The lower ends of the two vertical plate frames 720 located on the left side of the rear of the base 500 can be connected to the horizontal plate frame 710, and the upper ends thereof can be opened upward. In addition, the lower ends of the two vertical plate frames 720 disposed on the right side of the rear side of the base 500 can be connected to the lower horizontal plate frame 710, and the upper ends thereof can be opened upward. In addition, the upper ends of the vertical plate frames 720 are disposed on the relative left sides of the two vertical plate frames 720, the two vertical plate frames 720 are disposed on the right side of the rear side of the base 500, and the upper ends of the vertical plate frames 720 can be connected to the upper horizontal plate frame 710, the upper ends of the vertical plate frames 720 are disposed on the relative right sides of the two vertical plate frames 720, and the two vertical plate frames 720 are disposed on the left side of the rear side of the base 500.

[0085] One or more avoidance spaces 700a may be formed between the vertical plate frame 720 and the lower horizontal plate frame 710. When the rear guide 620 rises or falls, the avoidance spaces 700a may prevent the guide 600 from interfering with the plate frame 700. For example, the rear guide 620 may have a shape in which its left and right ends further extend backward. The width of the left and right ends of the rear guide 620 may be less than the length of the lower horizontal plate frame 710.

[0086] Therefore, even if an unpredictable force is applied from the outside while a vertically long electronic component is placed in the socket 510 and is erected by the board frame 700 and transferred from a handler (sorter) or transferred from the outside by a cart, the electronic component can be protected from damage and maintained in a stable supported state.

[0087] The front hinge part 810 can provide a predetermined rotation axis for the guide part 600. For example, the front hinge part 810 can be disposed adjacent to the front guide part 610 and provide a rotation axis for the guide part 600. In addition, the front hinge part 810 can be configured to rise or fall together with the front guide part 610 through the drive module 40. In addition, the front hinge part 810 can be provided to the front guide part 610 or the rear guide part 620. For example, in the case where the front hinge part 810 is provided to the front guide part 610 and connected to the front part of the bracket 10, the guide part 600 can rotate around the front part of the bracket 10.

[0088] For another example, in the case where the front hinge portion 810 is provided to the rear guide portion 620 and connected to the rear of the bracket 10, the guide portion 600 may rotate relative to the rear of the bracket 10. Preferably, the front hinge portion 810 may be provided to the front guide portion 610.

[0089] The air guide plate 900 may prevent the fluid entering the plate assembly 30 from leaking in the left-right direction. In other words, the air guide plate 900 may provide a fluid movement path through which most of the fluid from the front of the plate assembly 30 flows out to the rear of the plate assembly 30. In addition, the air guide plate 900 and the plate frame 700 may provide an opening portion O. The air guide plate 900 may include a first air guide plate 910 and a second air guide plate 920.

[0090] The first air guide plate 910 may be disposed at one side of the base 500. An upper end of the first air guide plate 910 may be vertically spaced apart from the plate frame 700. A lower end of the first air guide plate 910 may be disposed close to an upper surface of the base 500.

[0091] In addition, when the first air guide plate 910 and the second air guide plate 920 are viewed from the left or right side, the first air guide plate 910 and the second air guide plate 920 may have different areas. For example, the distance between the upper end of the first air guide plate 910 and the base 500 may be equal to the distance between the upper end of the second air guide plate 920 and the base 500. In addition, the distance between the lower end of the first air guide plate 910 and the base 500 may be smaller than the distance between the lower end of the second air guide plate 920 and the base 500. In other words, the height of the lower end of the first air guide plate 910 may be smaller than the height of the lower end of the second air guide plate 920. In addition, the first air guide plate 910 may be arranged so that its lower end is not spaced apart from the base 500.

[0092] The second air guide plate 920 may be disposed on the other side of the base 500. For example, the second air guide plate 920 may be disposed on the opposite side of the first air guide plate 910. The second air guide plate 920 may be disposed to face the first air guide plate 910. The second air guide plate 920 may be spaced apart upward from the substrate terminals to prevent a short circuit from occurring at the substrate terminals included in the base 500.

[0093] The length of the first air guide plate 910 extending in the up-down direction may be longer than the length of the second air guide plate 920 extending in the up-down direction. In addition, the height of the upper end of the first air guide plate 910 may be the same as the height of the upper end of the second air guide plate 920. For example, the spacing distance between the upper end of the first air guide plate 910 and the horizontal plate frame 710 may be the same as the spacing distance between the upper end of the second air guide plate 920 and the horizontal plate frame 710.

[0094] The opening portion O may include a first opening portion O1 and a second opening portion O2. The first opening portion O1 may be disposed between the upper end of the first air guide plate 910 and the plate frame 700. The first opening portion O1 may prevent the fluid supplied from front to back from accumulating in the fluid moving space S. More specifically, the first opening portion O1 may prevent a vortex from being generated due to the fluid being retained in the fluid flow space S or the fluid from flowing backward from back to front.

[0095] The second opening portion O2 may be provided between the lower end of the first air guide plate 910 and the base 500. The substrate terminal may be exposed through the second opening portion O2. In addition, the second opening portion O2 may have a predetermined height to prevent the air guide plate 900 from contacting the substrate terminal or a semiconductor device provided around the substrate terminal.

[0096] In addition, the air guide plate 900 may have a plurality of through holes 900a spaced apart from each other in the front-rear direction. Through the through holes 900a, the operator can check the state of the plurality of electronic components D placed on the base 500. The plurality of through holes 900a may be arranged in a row in the front-rear direction. The plurality of through holes 900a arranged in a row may have a lower height than the upper end of the electronic component D. In other words, even if the height of the electronic component D is lowered, the operator can check the state of the electronic component D through the through holes 900a.

[0097] The plurality of perforations 900a may be arranged in a plurality of rows. For example, the plurality of perforations 900a may be spaced apart from each other in the up-down direction and the front-back direction. For example, through the perforations 900a formed in the up-down direction, the operator may check the arrangement state of the electronic components D having different heights. In addition, through the perforations 900a formed in the front-back direction, the operator may check whether the electronic components D are tilted in the front-back direction (whether they are improperly placed).

[0098] As another example, a defect detection sensor (not shown) disposed in the chamber assembly 50 can detect, through the through-hole 900a, whether the electronic components D are tilted in the front-to-back direction (whether they are improperly positioned).

[0099] For another example, the chamber assembly 50 may further include a height sensor for measuring the height of the electronic component D. The height of the electronic component D may be defined as a distance between an upper end of the electronic component D placed on the base 500 and the base 500 .

[0100] A plurality of plate assemblies 30 may be provided. The plurality of plate assemblies 30 may be arranged in an up-and-down direction. The plurality of plate assemblies 30 may be fixedly supported by being connected to the bracket 10. The plate assembly 30 may include a first plate assembly 31 and a second plate assembly 32.

[0101] The first plate assembly 31 may be disposed above the second plate assembly 32. In addition, the guide portion 600 of the second plate assembly 32 may be disposed below the base 500 of the first plate assembly 31. In other words, the first plate assembly 31 and the second plate assembly 32 may be spaced apart from each other in the up-and-down direction. The guide portion 600 of the second plate assembly 32 may be configured to rotate around the base 500 of the first plate assembly 31. In addition, the front guide portion 610 of the second plate assembly 32 may be disposed between the bottom of the first plate assembly 31 and the top of the second plate assembly 32.

[0102] The driving module 40 may drive the air supply unit 20. In addition, the driving module 40 may drive the driving shaft 52 described below. The driving module 40 may include a lifting driver 41 and a rotating driver 42. The lifting driver 41 may move the driving shaft 52 in the up-down direction. For example, the lifting driver 41 may move the first driving shaft 52-1 included in the driving shaft 52 in the up-down direction. In addition, the lifting driver 41 may move the auxiliary driving shaft 55 described below up-down. An example of the lifting driver 41 may be a brake.

[0103] The rotary driver 42 may include a first rotary driver 42-1 and a second driver 42-2, wherein the first rotary driver 42-1 can rotate the second drive shaft 52-2 included in the drive shaft 52 around a rotation axis extending in the up-down direction, and the second driver 42-2 can rotate the first drive shaft 52-1 around a rotation axis extending in the up-down direction.

[0104] The chamber assembly 50 may provide an accommodation space for accommodating the bracket 10. The bracket 10 may be selectively detached from the accommodation space of the chamber assembly 50. For example, the bracket 10 may be manually or automatically held in or detached from the accommodation space provided by the chamber frame 51. The chamber assembly 50 may include a chamber frame 51, a drive shaft 52, a capture portion 53, an auxiliary capture portion 54, an auxiliary drive shaft 55, and a bracket holder 56.

[0105] The chamber frame 51 may support the drive shaft 52, the capture portion 53, the auxiliary capture portion 54, and the auxiliary drive shaft 55. The chamber frame 51 may support the rack 10 held in the accommodation space. The chamber frame 51 may have a chamber roller that allows the rack 10 to slide into and be held in the accommodation space. By means of the chamber roller, the friction force applied to the rack 10 when the rack 10 is accommodated in the accommodation space may be reduced.

[0106] The driving shaft 52 may include a first driving shaft 52 - 1 and a second driving shaft 52 - 2 . The first driving shaft 52 - 1 may be driven in the up-down direction or rotate around a rotation axis extending in the up-down direction. The first driving shaft 52 - 1 may be connected to the chamber frame 51 to be close to an edge of the chamber frame 51 .

[0107] The second driving shaft 52-2 may be driven to rotate about a rotation axis extending in the up-down direction. The second driving shaft 52-2 may be connected to the chamber frame 51 to be close to an edge of the chamber frame 51. The second driving shaft 52-2 may be spaced apart from the first driving shaft 52-1 in the front-rear direction.

[0108] The capture portion 53 can be connected to the first drive shaft 52-1 and move with the first drive shaft 52-1. For example, when the first drive shaft 52-1 is driven in the up-down direction, the capture portion 53 can move in the up-down direction with the first drive shaft 52-1. The capture portion 53 can apply downward pressure to the capture support protrusion 200b by moving downward, or can release the pressure on the capture support protrusion 200b by moving upward. When the first drive shaft 52-1 is driven to rotate, the capture portion 53 can rotate with the first drive shaft 52-1. For example, when the bracket holder 56 is in a detachable state, the first drive shaft 52-1 can be driven to rotate so that the capture portion 53 is oriented in a direction that deviates from the front-to-back direction. In addition, when the bracket holder 56 is in an anti-disassembly state, the first drive shaft 52-1 can be driven to rotate so that the capture portion 53 is oriented in a direction parallel to the front-to-back direction.

[0109] The detachable state may refer to a state in which the bracket 10 is detachable from the chamber assembly 50. The anti-detachment state may refer to a state in which the bracket 10 is prevented from being detached from the chamber assembly 50 by external force or vibration applied to the aging chamber apparatus 1 when the bracket 10 is mounted to the chamber assembly 50.

[0110] Even though not shown, a plurality of catching parts 53 may be provided. The plurality of catching parts 53 may be arranged to be spaced apart from each other in the up-down direction, and the number thereof may correspond to the number of catching support protrusions 200b.

[0111] The auxiliary catching portion 54 may be connected to the auxiliary driving shaft 55 and move together with the auxiliary driving shaft 55. For example, when the auxiliary driving shaft 55 is driven in the up-down direction, the auxiliary catching portion 54 may move in the up-down direction together with the auxiliary driving shaft 55. The auxiliary catching portion 54 may apply downward pressure to the front guide portion 610 by moving downward, and release the pressure on the front guide portion 610 by moving upward.

[0112] The support holder 56 can be connected to the second drive shaft 52-2 and rotate with the second drive shaft 52-2. When the support 10 is mounted to the chamber assembly 50, the support holder 56 can be placed in an anti-disassembly state by rotating to a position adjacent to one side of the support 10. In addition, before the support 10 is mounted to the chamber assembly 50 or when the support 10 is removed from the chamber assembly 50, the support holder 56 can be placed in a removable state by rotating away from the support 10. The support holder 56 can be set on the left or right side of the chamber frame 51. A plurality of support holders 56 can be provided. For example, a plurality of support holders 56 can be set on the left or right side of the chamber frame 51 while being spaced apart from each other in the front-to-back direction. The support holder 56 can be a connector that simultaneously connects the terminals of a plurality of plate assemblies 30 to the connection sockets of the chamber assembly 50.

[0113] The controller 60 may control the lifting driver 41, the first rotating driver 42-1, and the second rotating driver 42-2. In addition, the controller 60 may determine whether to perform an aging test based on the detection result of the defect detection sensor. For example, when the defect detection sensor detects that the electronic component D is improperly placed, the controller 60 may interrupt the operation of the driving module 40. In addition, the controller 60 may control the driving module 40 to adjust the rotation angle of the guide portion 600 based on the detection result of the height sensor. The controller 60 may be implemented by a computing device including a microprocessor, and its implementation method is obvious to those skilled in the art, so further description thereof will be omitted.

[0114] Hereinafter, the operation and effects of the aging chamber apparatus 1 according to the embodiment of the present invention will be described.

[0115] The aging chamber apparatus 1 may mount a rack 10 on a chamber assembly 50, on which a plurality of electronic components D required for an aging test are mounted. The rack 10 may move toward the chamber assembly 50 while being supported by a transport vehicle (eg, a cart).

[0116] As the rack 10 gets closer and closer to the chamber assembly 50, the chamber door (not shown) provided on the chamber assembly 50 is opened, and the rack holder 56 is rotated, so that the chamber assembly 50 is fully opened to face the rack 10. Thereafter, in the open state of the chamber assembly 50, the rack 10 is accommodated in the accommodation space of the chamber assembly 50, so that the rack 10 can be installed on the chamber assembly 50.

[0117] Once the rack 10 is mounted on the chamber assembly 50, the rack holder 56 can be rotated so that the rack holder 56 is adjacent to the left or right side of the rack 10. The rack holder 56 can be placed in a disassembly-proof state by the rotation of the rack holder 56. Afterwards, the chamber door can be closed.

[0118] Once the chamber door is closed, the capture portion 53 may be driven to face a direction parallel to the arrangement direction so that the capture portion 53 is arranged to face the capture support protrusion 200b. The capture portion 53 may be driven to move downward while facing the capture support protrusion 200b, so that the lifting unit 200 is lowered and the height of the rear guide portion 620 is adjusted accordingly. On the other hand, the capture portion 53 may not move downward. In addition, as the height of the electronic component D decreases, preferably, the height of the rear guide portion 620 decreases, and further, the height of the front guide portion 610 may also decrease. However, the height of the front guide portion 610 may be greater than or equal to the height of the rear guide portion 620.

[0119] When the height of the guide portion 600 is adjusted, the air supply portion 20 can be driven to perform an aging test on the electronic component D.

[0120] Since the guide portion 600 is driven according to the height of the matching electronic component D, the aging chamber equipment 1 can create the same temperature conditions for different types of electronic components D without replacing parts, thereby eliminating the trouble of replacing parts.

[0121] Above, the examples of the present invention are described as specific embodiments, but these are only examples, and the present invention is not limited thereto. According to the technical ideas disclosed in this specification, it should be interpreted as having the widest scope. Those skilled in the art can realize patterns of undisclosed shapes by combining / replacing the disclosed embodiments, which does not depart from the scope of the present invention. In addition, those skilled in the art can easily change or modify the disclosed embodiments according to this specification, and it is obvious that such changes or modifications are within the scope of the present invention.
