Description

Technical Field

[0001] This invention relates to the field of H01L technology, and more specifically, to a DBC splitting fixture and its application. Background Technology

[0002] The purchased DBC raw materials are in the form of motherboards, that is, each motherboard has multiple products separated by cutting grooves. After welding, the motherboard needs to be manually divided into individual modules. However, in this process, the distance between modules is small, and aluminum wires may be touched during separation, causing the aluminum wires to collapse and posing a risk of short circuit failure. At the same time, PIN pins may be touched, causing the PIN pins to become misaligned and fail. Currently, there is no fixture to separate DBCs. Summary of the Invention

[0003] To address some problems existing in the prior art, the first aspect of the present invention provides a DBC splitting fixture, comprising: a DBC fixing block 1, a connecting rod 2, and a DBC splitting pressure block 3. The DBC fixing block 1 and the DBC splitting pressure block 3 are connected by the connecting rod 2. The DBC splitting pressure block 3 has a first slot 4 inside, and a limit block 5 is provided inside the first slot 4. The DBC fixing block 1 has a second slot 12 inside, and the bottom side of the second slot 12 and the bottom side of the first slot 4 are connected by a DBC sliding plate 6.

[0004] In one embodiment, the DBC fixing block 1 includes a first DBC fixing segment 7 and a second DBC fixing segment 8; the first DBC fixing segment 7 and the second DBC fixing segment 8 are detachably connected.

[0005] Preferably, the first DBC fixing block 7 and the second DBC fixing block 8 are connected by screws.

[0006] The arrangement of the first DBC fixed block 7 and the second DBC fixed block 8 in this application facilitates assembly and manufacturing, and also makes it easy to adjust the movement of the DBC material on the DBC slide plate 6.

[0007] In one embodiment, the end of the connecting rod 2 that connects to the DBC fixing block 1 is provided with a circular opening 9.

[0008] In this application, screws are used to connect the connecting rod 2 and the DBC fixing block 1 through the circular opening 9.

[0009] Preferably, the DBC fixing block 1 is provided with an ear plate 10 that cooperates with the connecting rod 2.

[0010] Preferably, the ear plate 10 and the connecting rod 2 are in close contact.

[0011] Preferably, the ear plate 10 is integrally connected with the DBC fixing block 1.

[0012] Preferably, the length of the ear plate 10 is less than the length of the connection portion between the connecting plate 2 and the DBC fixing block.

[0013] The ear plate 10 in this application ensures that the DBC splitting fixture is stable during the splitting process, preventing the aluminum wire from collapsing or the PIN pin from becoming crooked due to the tilting of the fixture during the splitting process.

[0014] Preferably, the end of the connecting rod 2 that connects to the DBC split plate pressure block 3 is provided with a through hole 11.

[0015] The number of through holes 11 described in this application is not particularly limited, and those skilled in the art can make conventional selections.

[0016] In one embodiment, the number of through holes 11 is 2.

[0017] In this application, there are two through holes 11, which further ensures the stability of the pressure plate.

[0018] Preferably, the connecting rod 2 and the DBC split plate pressure block 3 are detachably connected through the through hole 11.

[0019] The detachable connection method described in this application is not particularly limited, and those skilled in the art can make conventional choices.

[0020] Preferably, the through hole 11 connects the connecting rod 2 and the DBC split plate pressure block 3 by screws.

[0021] Preferably, the length of the connecting rod 2 is 50-55mm, and more preferably 52.5mm.

[0022] More preferably, the length of the connection portion between the connecting rod 2 and the DBC fixing block 1 is 10-15mm, more preferably 13mm.

[0023] More preferably, the length of the connection portion between the connecting rod 2 and the DBC split plate pressure block 3 is 7-8mm, more preferably 7.5mm.

[0024] In this application, the total length of the connecting rod 2 and the lengths of its respective connections with the DBC fixing block 1 and the DBC partitioning block 3 are set such that the lengths that do not overlap with the DBC partitioning block 3 and the DBC fixing block 1 are 27-38mm, which ensures the convenience of observation during partitioning and improves the efficiency of partitioning.

[0025] In one embodiment, the surface of the DBC slide plate 6 is provided with dividing lines at equal intervals along its length.

[0026] The dividing line in this application facilitates the determination of the position of the DBC raw material during plate separation, ensuring the success rate of plate separation.

[0027] In one embodiment, the height of the first slot 4 is 12-20mm, preferably 15mm.

[0028] In one embodiment, the height of the second slot 12 is 15-20 mm, preferably 18 mm.

[0029] In this application, the heights of the first slot 4 and the second slot 12 are matched with the DBC material to ensure the mobility of the DBC, while facilitating the function of the subsequent positioning block 5.

[0030] A second aspect of the present invention provides an application of the DBC slitting fixture in the slitting of DBC raw materials.

[0031] In existing technologies, the separation of DBC raw materials is all done manually. A flowchart of the manual separation process can be found here. Figure 2 During manual board separation, issues such as aluminum wire collapse (as shown in point 3) and other problems can easily occur. Figure 4 The PIN pin is bent.

[0032] Compared with the prior art, the present invention has the following advantages:

[0033] (1) The first DBC fixing block and the second DBC fixing block are connected by screws, which makes assembly and manufacturing convenient and facilitates the adjustment of the movement of the DBC material on the DBC slide plate.

[0034] (2) The ear plate setting makes the DBC splitting fixture stable during the splitting process, avoiding the aluminum wire collapse or PIN pin misalignment caused by the tilting of the fixture during the splitting process.

[0035] (3) The length distribution of the connecting rods set in this application ensures the convenience of observation during plate separation and improves the efficiency of plate separation;

[0036] (4) Using the DBC splitting fixture in this application to split the DBC raw material avoids the collapse of aluminum wires and the skew of PIN pins when splitting manually, which not only improves the splitting efficiency, but also ensures the success rate of splitting.
