DETAILED DESCRIPTION

[0036] Drawings will be used below to disclose embodiments of the present disclosure. For the sake of clear illustration, many practical details will be explained together in the description below. However, it is appreciated that the practical details should not be used to limit the claimed scope. In other words, in some embodiments of the present disclosure, the practical details are not essential. Moreover, for the sake of drawing simplification, some customary structures and elements in the drawings will be schematically shown in a simplified way. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

[0037] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this disclosure belongs. 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.

[0038] Reference is made to FIGS. 1-2. FIG. 1 is a schematic view of a testing equipment 100 according to an embodiment of the present disclosure. FIG. 2 is another schematic view of the testing equipment 100 of FIG. 1, in which the frame 140, the platform 150, the probe holder 160 and the probe 170 are omitted. In this embodiment, as shown in FIGS. 1-2, a testing equipment 100 includes a tester 110, a load board 120 and an adapter 130. The load board 120 is disposed on the tester 110 and is practically a circuit board. The adapter 130 is disposed on the load board 120 and configured to support a device under test 200 (please see FIGS. 5-6 for the device under test 200). The adapter 130 is electrically connected to the load board 120 and the device under test 200. In practical applications, the tester 110 includes a transmitter 111 and a receiver 112. The transmitter 111 is configured to transmit a testing signal to the device under test 200 through the load board 120 and the adapter 130. The receiver 112 is configured to receive a feedback signal from the device under test 200 through the load board 120 and the adapter 130. For example, the tester 110 is a high-speed memory tester while the device under test 200 is a memory card, such as a dynamic random-access memory (DRAM).

[0039] As mentioned above, since the adapter 130 is electrically connected to the load board 120 and the device under test 200, transmission lines will not be required to connect between the load board 120 and the device under test 200. In this way, the limitation to the testing speed due to the presence of transmission lines can be avoided. On the contrary, the application of the adapter 130 connected between the load board 120 and the device under test 200 allows internal probing at high speeds during an electrical test to the device under test 200.

[0040] Furthermore, as shown in FIG. 1, the testing equipment 100 further includes a frame 140, a platform 150, a probe holder 160 and at least one probe 170. The frame 140 defines an accommodation space AS. The tester 110 and the load board 120 are at least partially located in the accommodation space AS defined by the frame 140. The platform 150 is connected with the frame 140. The platform 150 has an opening OP1 communicated with the accommodation space AS defined by the frame 140. The adapter 130 is exposed through the opening OP1 of the platform 150. The probe holder 160 is disposed on the platform 150. The probe 170 is held by the probe holder 160. The probe holder 160 is configured to control the probe 170 to contact with the device under test 200 through the opening OP1 of the platform 150. For the sake of drawing simplification, the frame 140, the platform 150, the probe holder 160 and the probe 170 are omitted in FIG. 2.

[0041] In addition, as shown in FIG. 1, the testing equipment 100 further includes a plurality of rollers 180. The rollers 180 are connected to a side of the tester 110 away from the load board 120. Each of the rollers 180 is configured to roll over a floor. In this way, a user can move the tester 110 between different working locations in an effective and easy manner.

[0042] Moreover, as shown in FIG. 1, the testing equipment 100 further includes a microscope 190 and a display device 195. The microscope 190 slidably is connected with the platform 150 and configured to obtain an image of the device under test 200 through the opening OP1 of the platform 150. The display device 195 is connected with the frame 140 and signally connected with the microscope 190. In this way, the image obtained by the microscope 190 can be displayed on the display device 195.

[0043] Reference is made to FIG. 3. FIG. 3 is a top view of the adapter 130 of FIGS. 1-2. In this embodiment, as shown in FIGS. 2-3, the adapter 130 includes a socket 131 and a connecting plate 132. The socket 131 is disposed on the load board 120 and electrically connected with the load board 120. The connecting plate 132 is detachably and electrically connected with the socket 131. The connecting plate 132 defines a probe area PA (please see FIG. 3 for the probe area PA) located away from the load board 120. The probe area PA is configured to place the device under test 200 thereon, and the connecting plate 132 is electrically connected with the device under test 200.

[0044] To be specific, as shown in FIGS. 2-3, the connecting plate 132 includes a plate body 133 and a plurality of conductive portions 134. The probe area PA is located on the plate body 133. The conductive portions 134 are located on the probe area PA and configured to electrically connect with the device under test 200. In other words, the conductive portions 134 serve as electrical contact points to contact with the device under test 200.

[0045] Moreover, in this embodiment, at least one of the conductive portions 134 is shaped as a line structure. For example, as shown in FIGS. 2-3, both of the conductive portions 134 are respectively shaped as a line structure. In addition, the conductive portions 134 are separated from each other in the probe area PA.

[0046] Reference is made to FIG. 4. FIG. 4 is a top view of the adapter 130 of FIG. 3, in which the connecting plate 132 is detached from the socket 131. In this embodiment, as shown in FIG. 4, the connecting plate 132 further includes a terminal portion 135. The terminal portion 135 is connected with an edge of the plate body 133 and electrically connected with the conductive portions 134. The terminal portion 135 is configured to be inserted into the socket 131, such that the terminal portion 135 is electrically connected with the socket 131.

[0047] Furthermore, as shown in FIGS. 2-4, the adapter 130 further includes a pair of guiding portions 136. The guiding portions 136 are connected with two opposite ends of the socket 131. The guiding portions 136 are configured to guide and hold the connecting plate 132 therebetween.

[0048] Reference is made to FIGS. 5-6. FIG. 5 is a top view of the adapter 130 of FIG. 3, in which the device under test 200 is placed on the probe area PA. FIG. 6 is a cross-sectional view along the section line A-A of FIG. 5. In this embodiment, as shown in FIGS. 5-6, the load board 120 has a surface SF away from the tester 110 (please see FIGS. 1-2 for the tester 110). The socket 131 is disposed on the surface SF of the load board 120. The socket 131 has an opening OP2 (please see FIG. 6 for the opening OP2) facing to a direction D intersecting with a normal N of the load board 120, and the connecting plate 132 is detachably inserted into the opening OP2, such that the connecting plate 132 is connected with the socket 131 along the direction D to form an electrical connection. In practical applications, the direction D is perpendicular to the normal N of the load board 120 and is parallel with the surface SF.

[0049] In addition, as shown in FIGS. 1-3 and 5-6, a vertical projection of the adapter 130 to the load board 120 is located within the surface SF. In other words, the size of the adapter 130 is smaller than the load board 120 as viewed along the normal N of the surface SF.

[0050] Furthermore, as shown in FIG. 6, the connecting plate 132 is at least partially parallel with the load board 120. In this way, an orientation of the device under test 200 placed on the connecting plate 132 is substantially held in a horizontal manner, which facilitates the application of the probe 170 (please see FIG. 1 for the probe 170) on the device under test 200 for testing.

[0051] In conclusion, the aforementioned embodiments of the present disclosure have at least the following advantages:

[0052] (1) The application of the adapter connected between the load board and the device under test allows internal probing at high speeds during an electrical test to the device under test.

[0053] (2) Since the connecting plate is at least partially parallel with the load board, an orientation of the device under test placed on the connecting plate is substantially held in a horizontal manner, which facilitates the application of probes on the device under test for testing.

[0054] Although the present disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.

[0055] It will be apparent to the person having ordinary skill in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the present disclosure. In view of the foregoing, it is intended that the present disclosure cover modifications and variations of the present disclosure provided they fall within the scope of the following claims.
