Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.
[0026] like Figures 1 to 3 As shown, the embodiment of the present application provides a bar packaging test device 1, which can effectively test the performance of the bar packaging module 2 and accurately verify the working reliability of the bar packaging module 2.
[0027] The bar package test device 1 includes a base 10, which is the main bearing structure of the bar package test device 1 and can bear other test structures and the bar package module 2 to be tested. The base 10 is provided with a bar mounting structure 11, a first connection electrode 12 and a second connection electrode 13. The bar mounting structure 11 and the first connection electrode 12 are conductively arranged, and the second connection electrode 13 is insulated. That is, when the bar package module 2 to be tested is not loaded, the bar mounting structure 11 and the first connection electrode 12 are conductively connected, and the bar mounting structure 11 and the second connection electrode 13 are insulated. That is, when the bar package module 2 to be tested is not loaded, the bar mounting structure 11 and the first connection electrode 12 are conductively connected, and the bar mounting structure 11 and the second connection electrode 13 are insulated.
[0028] The bar mounting structure 11 is configured to mount the bar packaging module 2 and is conductively connected to one electrode, such as the positive electrode, of the bar packaging module 2, while the second connecting electrode 13 is configured to be conductively connected to the other electrode, such as the negative electrode, of the bar packaging module 2. That is, after the bar packaging module 2 to be tested has been mounted, the first connecting electrode 12, the bar mounting structure 11, the bar packaging module 2 and the second connecting electrode 13 are conductively connected in sequence to form a through series circuit; in this way, the bar packaging module 2 can be powered on and the performance of the bar packaging module 2 can be tested by connecting the positive and negative electrodes of a power supply or a multimeter to the first connecting electrode 12 and the second connecting electrode 13 respectively.
[0029] Here, a water cooling channel 14 is provided inside the base 10. Cooling water can flow in the water cooling channel 14. The cooling water takes away the heat generated by the bar packaging module 2 during the flow process, so that the temperature of the bar packaging module 2 is maintained within a desired temperature range.
[0030] Compared with the related art, the bar packaging test device 1 provided in the embodiment of the present application utilizes the bar mounting structure 11 to mount the bar packaging module 2 to be tested, so that the first connecting electrode 12, the bar mounting structure 11, the bar packaging module 2 and the second connecting electrode 13 are conductively connected in sequence to form a through series circuit, and then the first connecting electrode 12 and the second connecting electrode 13 are electrically connected to power the bar packaging module 2 and perform performance testing. At the same time, the water cooling channel 14 is used to water-cool the bar packaging module 2 to keep the temperature of the bar packaging module 2 within the required temperature range, so that the performance of the bar packaging module 2 can be effectively tested and the working reliability of the bar packaging module 2 can be accurately verified.
[0031] In some embodiments, the base 10 may be provided with a receiving groove 15, and the bar mounting structure 11, the first connecting electrode 12, and the second connecting electrode 13 are respectively arranged in the receiving groove 15. The receiving groove 15 can be used to more reliably protect the bar mounting structure 11, the first connecting electrode 12, and the second connecting electrode 13 to avoid accidental structural damage.
[0032] In some examples, the bar mounting structure 11, the first connecting electrode 12, and the second connecting electrode 13 can protrude out of the accommodating groove 15 along the depth direction of the accommodating groove 15. In this way, the bar mounting structure 11, the first connecting electrode 12, and the second connecting electrode 13 are respectively partially located in the accommodating groove 15 and partially located outside the accommodating groove 15. On the one hand, the bar mounting structure 11, the first connecting electrode 12, and the second connecting electrode 13 can be reliably protected by the accommodating groove 15, and on the other hand, the bar packaging module 2 can be easily mounted on the bar mounting structure 11, and the first connecting electrode 12 and the second connecting electrode 13 can be easily connected to the power-on test.
[0033] The material of the base 10 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some embodiments, the base 10 can be a metal base 10 made of a single metal material such as copper or other alloy materials. The bar mounting structure 11 and the first connecting electrode 12 can be respectively formed as bosses on the metal base 10, so that the bar mounting structure 11 and the first connecting electrode 12 can be directly conductively connected or indirectly conductively connected through the base 10; and the second connecting electrode 13 and the metal base 10 are insulated to ensure safe insulation between the first connecting electrode 12 and the second connecting electrode 13 to avoid accidental short circuits. In some examples, a receiving groove 15 can be provided on the base 10, and the bar mounting structure 11 and the first connecting electrode 12 can be respectively formed as bosses at the bottom of the receiving groove 15.
[0034] The insulation setting between the base 10 and the second connecting electrode 13 can be implemented in different ways, and the embodiments of the present application are not limited to this. In some examples, the bar packaging test device 1 may include a ceramic sheet 16, and the ceramic sheet 16 is arranged between the base 10 and the second connecting electrode 13; that is, the ceramic sheet 16 can be arranged on the base 10, for example, in a groove, and the second connecting electrode 13 can be arranged on a side surface of the ceramic sheet 16 away from the base 10. The ceramic sheet 16 has an insulating property and can achieve insulation isolation between the base 10 and the second connecting electrode 13.
[0035] In some embodiments, the bar mounting structure 11 may have a mounting surface 111, which is located on the side of the first connecting electrode 12 away from the base 10 and on the side of the second connecting electrode 13 away from the base 10. In this way, the height of the plane where the mounting surface 111 is located is higher than the side surface of the first connecting electrode 12 away from the base 10, i.e., its top surface, and higher than the side surface of the second connecting electrode 13 away from the base 10, i.e., its top surface, so that a high-low layout structure is formed between the bar mounting structure 11 and the first connecting electrode 12 / the second connecting electrode 13, so that the bar packaging module 2 can be reliably mounted on the mounting surface 111 located at the highest point, so as to prevent the probe electrodes such as the positive and negative poles of the power supply or the multimeter from accidentally contacting the bar packaging module 2, thereby preventing the bar packaging module 2 from being accidentally damaged.
[0036] In some embodiments, a side surface of the first electrode 12 away from the base 10 and a side surface of the second electrode 13 away from the base 10 are flush, forming a structure in which two electrodes are arranged flush with each other, thereby increasing the operational convenience and reliability when connecting an external probe electrode.
[0037] The conductive connection between the second connection electrode 13 and the bar packaging module 2 can be achieved through different connection methods, which are not limited in the embodiments of the present application. In some embodiments, the bar packaging test device 1 may include a conductive connection line, and the second connection electrode 13 may be conductively connected to the other electrode of the bar packaging module 2 through the conductive connection line. The type of the conductive connection line can be determined according to actual needs, and different types such as gold wire, copper and aluminum wire can be used, which are not limited in the embodiments of the present application.
[0038] The shape of the second connection electrode 13 can be determined according to actual needs, and the embodiment of the present application does not limit this. In some embodiments, the second connection electrode 13 can be an L-shaped conductive block, and the L-shaped conductive block is respectively arranged relative to the adjacent two side surfaces of the bar mounting structure 11. In this way, the second connection electrode 13 is arranged around the adjacent two sides of the bar mounting structure 11, realizing a relatively compact and reliable layout structure.
[0039] In some embodiments, the bar package module 2 may include a laser bar and a heat sink, one pole of the laser bar, such as the positive pole, is conductively fixed on a side surface of the heat sink, and a side surface of the heat sink away from the laser bar is conductively mounted on the bar mounting structure 11, and the second electrode 13 is conductively connected to the other pole of the laser bar, such as the negative pole. Here, the laser bar may include a plurality of semiconductor laser chips, and the laser bar may be welded to the heat sink by welding materials, or sintered to the heat sink by sintering materials, to form a reliable packaging structure.
[0040] The bar packaging test device provided in the embodiment of the present application is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
