It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0067] Reference will now be made to the drawings Figure 1 . Figure 1 A perspective view of a switch cover apparatus 100 according to an embodiment of the present application is shown. In this embodiment, as shown in Figure 1 , a switch cover apparatus 100 includes a base plate 110, a guide structure 120, and at least one test socket 130. In a preferred embodiment, the base plate 110 can be a test circuit board, such as a burn-in circuit board. The guide structure 120 extends at least partially along a first direction Dl. For example, the guide structure 120 can be disposed on the base plate 110, or the base plate 110 and the guide structure 120 can be disposed on separate frames. The test socket 130 includes a base portion 131, a cover portion 132, a locking portion 133, and a bendable actuation portion 134, and is also referred to as a "clamshell test socket". The base portion 131 is disposed on the base plate 110 and is configured to receive a die (not shown), which can be a packaged finished IC or a bare die. The cover portion 132 is resiliently pivoted to the base portion 131 and is configured to cover the base portion 131. As shown in Figure 1 , the cover portion 132 is covering the base portion 131 to sandwich the die therebetween. The locking portion 133 is disposed on the base portion 131 and is configured to snap the cover portion 132. As shown in Figure 1 , the locking portion 133 is snapping the cover portion 132 to maintain the cover portion 132 covering the base portion 131. The bendable actuation portion 134 has opposite first and second ends 134a and 134b. The first end 134a is pivoted to the base portion 131 and is mechanically connected to the locking portion 133, and is configured to actuate the locking portion 133 to snap or unsnap the cover portion 132. The second end 134b is movably connected to the guide structure 120 along the first direction Dl. In a preferred embodiment, the base portion 131 can be a probe socket having a plurality of test probes for testing the die, and the cover portion 132 can include a temperature control component, such as a heater or a fan, for controlling the burn-in temperature of the die.

[0068] More specifically, as shown in Figure 1As shown, the bendable drive unit 134 includes a pivot 1341, a first connecting rod 1342, a second connecting rod 1343, and a guide member 1344. The pivot 1341 defines the aforementioned first end 134a and extends along a second direction D2, which is perpendicular to the first direction D1. The pivot 1341 is connected to one end of the first connecting rod 1342. One end of the second connecting rod 1343 is rotatably connected to the other end of the first connecting rod 1342. The guide member 1344 defines the aforementioned second end 134b and connects to the other end of the second connecting rod 1343.

[0069] Please refer to Figure 2 . Figure 2 To illustrate along Figure 1 A side view of the opening and closing cover device 100, wherein the telescopic arm 142 of the moving device 140 extends downward and connects to the guide member 1344. In this embodiment, as... Figure 2 As shown, the cover opening / closing device 100 further includes a moving device 140 (the moving device 140 is not shown for the sake of brevity in the drawings). Figure 1 (Middle). The moving device 140 is configured to connect to and drive the guide 1344 (i.e., the second end 134b) to move relative to the guide structure 120 in the first direction D1, so that the rotating shaft 1341 (i.e., the first end 134a) rotates relative to the bottom 131, thereby driving the locking part 133 to latch or release the cover part 132.

[0070] More specifically, such as Figure 2 As shown, the moving device 140 includes a main body 141 and a telescopic arm 142. The main body 141 is configured to move at least partially along a first direction D1 and a second direction D2, both of which are substantially horizontal. The telescopic arm 142 is connected to the main body 141 and configured to extend and retract along a third direction D3 to engage or disengage from the guide 1344 of the bendable drive unit 134. Figure 2 As shown, the telescopic arm 142 extends downward and connects to the guide member 1344. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other, and the third direction D3 is substantially perpendicular. Depending on the actual situation, the main body 141 of the moving device 140 can also move along the third direction D3.

[0071] Furthermore, such as Figure 2 As shown, the guide structure 120 includes an upper rail 121 and a lower rail 122. The upper rail 121 extends along a first direction D1, and the lower rail 122 is at least partially parallel to the upper rail 121, defining a gap G between them. The guide member 1344, constrained by the upper rail 121 and the lower rail 122, at least partially passes through the gap G. Driven by the telescopic arm 142, the guide member 1344 moves along the first direction D1 through the gap G between the upper rail 121 and the lower rail 122.

[0072] Please refer to Figures 3-5 . Figures 3-5 For illustration Figure 2 A schematic diagram showing the opening of the cover 132 relative to the bottom 131. For simplicity, the main body 141 of the moving device 140 is not shown in the diagram. Figures 3-5 In the middle. For example Figure 3 As shown, when the telescopic arm 142 continuously drives the guide member 1344 to move along the first direction D1 within the gap G, the guide member 1344 drives the second connecting rod 1343 to move, and causes the first connecting rod 1342, together with the rotating shaft 1341, to rotate relative to the bottom 131. Figure 4 As shown, when the guide 1344 reaches the target position P, the rotating shaft 1341 rotates relative to the bottom 131 by a certain angle, causing the locking part 133 to release the cover 132, and the cover 132 also elastically opens relative to the bottom 131. In fact, the way the locking part 133 engages or disengages the cover 132 can be easily accomplished by varying the shapes of the rotating shaft 1341 and the locking part 133, and by using different mechanical parts; this will not be elaborated upon here. Figure 5 As shown, the cover 132 is fully open relative to the bottom 131. In this case, the chip can be placed on the bottom 131, or the chip can be removed from the bottom 131. At this time, as... Figure 5 As shown, the telescopic arm 142 has retracted upwards and disengaged from the guide 1344.

[0073] Furthermore, such as Figures 1-5 As shown, the guide structure 120 further includes a plurality of sensing units 123. The sensing units 123 are distributed along the lower track 122 along the first direction D1, and each sensing unit 123 is configured to sense the guide element 1344. Figures 4-5 As shown, the sensing unit 123 corresponds to the target position P. Therefore, when the guide 1344 arrives at the target position P, the user can know from the signal of the sensing unit 123 that the cover 132 should be able to be elastically opened relative to the bottom 131. In addition, in practical applications, the sensing unit 123 can also be distributed along the first direction D1 on the upper track 121 according to the actual situation.

[0074] Furthermore, such as Figures 1-3 As shown, the guide structure 120 further includes a plurality of positioning portions 124. The positioning portions 124 are distributed along the lower rail 122 along the first direction D1, and are elastically connected to the lower rail 122 respectively, and are configured to provide positioning for the guide member 1344. Specifically, as... Figures 2-3 As shown, the positioning part 124 is at least partially aligned with the sensing unit 123, and the positioning part 124 also corresponds to the target position P and has a recessed surface 124S. Therefore, as shown in Figures 4 and 5, when the guide member 1344 reaches the target position P, the guide member 1344 will press against the positioning part 124 (the positioning part 124 is located at the target position P).Figures 4-5 The second link 1343 and the guide 1344 are blocked by the second link 1343 and the guide 1344, so please refer to Figures 1-3 The recessed surface 124S on the second link 1343 and the guide 1344 is limited by the recessed surface 124S, so the accuracy of the switch cover device 100 operation can be improved.

[0075] Please refer to Figures 6-7 . Figures 6-7 To illustrate Figure 5 The cover 132 covers the bottom 131. In actual operation, when the chip has been placed on the bottom 131, or the chip has been removed from the bottom 131, as shown in Figure 6 The telescopic arm 142 of the moving device 140 is further configured to push the cover 132, so that the cover 132 rotates relative to the bottom 131 to cover the bottom 131, until the locking portion 133 buckles the cover 132, as shown in Figure 7 At this time, the telescopic arm 142 drives the guide 1344 to move in the gap G in the opposite direction, and the form of the test seat 130 is as shown in Figure 2 Until the bendable driving portion 134 returns to the initial form, as shown in Figure 1 The work flow of placing the chip in the test seat 130 or removing the chip from the test seat 130 is also completed. Please refer to Figure 8 . Figure 8 To illustrate the switch cover device 100' according to another embodiment of the present application. Unlike the above-mentioned embodiment, in the present embodiment, as shown in Figure 8 The switch cover device 100' further includes a bearing structure 150, and the form of the test seat 130Z is also different from that of the test seat 130 in the above-mentioned embodiment.

[0076] First, in the present embodiment, as shown in Figure 8 The bearing structure 150 is at least partially parallel to the guide structure 120. For example, the bearing structure 150 can be provided on the bottom plate 110 or the above-mentioned frame. The bearing structure 150 is configured to at least partially move towards the guide structure 120, and the test seat 130Z is located between the guide structure 120 and the bearing structure 150.

[0077] Specifically, the bearing structure 150 includes a bracket 151 and a bearing piece 152. The bracket 151 is connected to the bottom plate 110 or the above-mentioned frame, and the bearing piece 152 is movably connected to the bracket 151 and is configured to move relative to the bracket 151 along the second direction D2 to approach or away from the guide structure 120. In fact, the way the bearing piece 152 moves relative to the bracket 151 can be easily achieved by equipping guide rails, different mechanical parts and / or various extendable parts, which will not be described here.

Figure 10 As shown in FIG. 9, when the first guide 1372 of the driving portion 137 is moved along the first direction D 1 in the gap G of the guide structure 120, the second cover portion 136 of the test socket 130Z is rotated relative to the first cover portion 135, and the second guide 1373 of the driving portion 137 is correspondingly moved upwardly. When the first guide 1372 reaches the target position P, the second guide 1373 is slightly higher than the resting structure 152. At this time, the resting structure 152 is moved relative to the support 151 to be close to the guide structure 120 and is at least partially positioned below the second guide 1373, and the second guide 1373 can be supported on the resting structure 152.

[0080] Please refer to Figure 11 . Figure 11 to illustrate a perspective view of the switch cover apparatus 100' along the direction of arrow A 2, wherein the first guide 1372 is connected to the extension arm 142 of the moving device 140.

[0082] Subsequently, in actual operation, when the chip has been placed on the bottom portion 131, or the chip has been taken away from the bottom portion 131, the telescopic arm 142 of the moving device 140 drives the first guide 1372 to move, so that the test seat 130Z returns to the form shown in FIG. 10. At this time, the supporting member 152 is away from the guide structure 120 along the second direction D2 relative to the bracket 151, so that the second guide 1373 of the driving portion 137 is no longer supported on the supporting member 152. Then, the telescopic arm 142 of the moving device 140 again drives the first guide 1372 to move in the opposite direction, so that the test seat 130Z returns to the form shown in FIG. 9, and the work flow of placing the chip in the test seat 130Z or taking the chip out of the test seat 130Z is also completed. Figure 9

[0083] In summary, the technical solutions disclosed in the above embodiments of the present application have at least the following advantages: The switch cover device can be applied to system level testing (System Level Testing) of chips or final testing (Final Testing) of chips, and the moving device moves in a single direction, that is, the action of the switch cover device opening and closing the cover can be controlled, so as to reduce the complexity and degree of freedom of the action of the switch cover. Furthermore, the switch cover device can simply and accurately open and close the test seat (including the clamshell test seat and the Z-shaped test seat), which is beneficial to improving the success rate of placing or picking up the chip by the switch cover. In addition, the switch cover device can replace manual opening and closing of the cover, so as to reduce the operation cost of testing.
