Description

Technical Field

[0001] This application relates to the field of semiconductor packaging, and more specifically, to a surface tension testing device for TOLL packaging. Background Technology

[0002] Before TOLL packaging of chips, a tensile test is required on the packaging tape to evaluate its connection strength and reliability during the packaging process. Packaging tape is a strip used to encapsulate and protect electronic components, circuit boards, or other products. It is typically made of plastic, polymer, or other materials and has a certain degree of adhesion and sealing performance. Tensile testing helps determine the tape's load-bearing capacity under external tensile or taut forces, ensuring the robustness and stability of the package.

[0003] A search revealed that Chinese patent CN118243501A discloses a tensile testing device for TOLL packaging face strips. This device stabilizes the two ends of the packaging face strip by winding it around two sets of upper and lower roll strip assemblies. Then, the two ends of the packaging face strip are clamped again by the fixed pressure block and the movable pressure block in two sets of clamps. The rounded corners on the fixed pressure block and the movable pressure block can support the packaging face strip and prevent the packaging face strip from being damaged by the sharp corners of the fixed pressure block and the movable pressure block.

[0004] The aforementioned device fixes one end of the packaging strip while the other end hangs freely under gravity. This fixing method is affected by the internal tension of the packaging strip, making it difficult to fix the packaging surface flat between the two clamps. During tensioning, the packaging strip is prone to uneven stress, affecting the accuracy of the tensile test. In view of this, we propose a packaging strip tensile testing device for TOLL packaging.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this application are:

[0024] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] Please see Figure 1 and Figure 2 This application provides a technical solution:

[0026] A tensile strength testing device for TOLL packaging includes a support base 1, a slide rail 101 on the support base 1, and two fixed seats 2 slidably mounted on the slide rail 101. Each fixed seat 2 includes an upper clamping plate 201 and a lower clamping plate 202, which are slidably connected. The lower clamping plate 202 is slidably connected to the slide rail 101. A tensile gauge 3 is fixedly mounted on one side of the support base 1, and a slider 4 is provided on the other side. The two lower clamping plates 202 are detachably connected to the tensile gauge 3 and the slider 4, respectively. A drive motor 5 is mounted on the support base 1, and a threaded rod 6 is connected to the output end of the drive motor 5. The threaded rod 6 is rotatably connected to the support base 1, passes through the slider 4, and is threadedly connected to the slider 4. The slider 4 is slidably mounted on the support base 1.

[0027] When testing the packaging strip, first pass one end of the packaging strip through the fixed seat 2 connected to the tension gauge 3, and then connect it to another fixed seat 2. The upper clamp 201 and lower clamp 202 are used to fix one end of the packaging strip. By pushing the fixed seat 2 connected to the end of the packaging strip along the slide rail 101, the packaging strip is pulled out from between the upper clamp 201 and lower clamp 202 of the other fixed seat 2, keeping the packaging strip flat. Until the fixed seat 2 connected to the end of the packaging strip moves to the slider 4, the lower clamp 202 is connected to the slider 4 with the help of the bolt, and the other end of the packaging strip is fixed. Finally, the drive motor 5 drives the threaded rod 6 to rotate, and the slider 4 pulls one of the fixed seats 2 to tension the packaging strip fixed between the two fixed seats 2 for tension testing.

[0028] like Figure 3 As shown, a support frame 203 is provided on the lower clamping plate 202, and the upper clamping plate 201 is slidably mounted on the support frame 203. A fixing member 7 is provided above the upper clamping plate 201, and the fixing member 7 is threadedly connected to the support frame 203. By rotating the fixing member 7, the user can move the fixing member 7 downward relative to the support frame 203 and press the upper clamping plate 201 downward, thereby fixing the end of the encapsulation strip between the upper clamping plate 201 and the lower clamping plate 202.

[0029] like Figure 4 As shown, a connector 701 is rotatably connected to the upper part of the fixing member 7. A cavity is opened in the middle of the connector 701, and a gear 702 is installed in the cavity. The gear 702 is connected and fixed to the fixing member 7. A handle 703 is fixedly connected to one side of the connector 701. A locking block 704 is slidably connected inside the handle 703. The end of the locking block 704 extends into the cavity and engages with the gear 702. An elastic element 705 is provided inside the handle 703, and the locking block 704 is elastically connected to the handle 703 through the elastic element 705. An adjusting rod 8 is rotatably connected inside the handle 703. One end of the adjusting rod 8 extends to the outside of the handle 703. An adjusting member 801 is slidably installed inside the handle 703. The adjusting member 801 is threadedly connected to the adjusting rod 8. The elastic element 705 is disposed between the adjusting member 801 and the slider 4.

[0030] When the user rotates the connector 701 via the handle 703, if the applied torque is insufficient to allow the locking block 704 to slide relative to the gear 702, the handle 703 can drive the fixing member 7 to rotate relative to the support frame 203, applying pressure to the upper clamping plate 201. As the clamping force between the upper clamping plate 201 and the lower clamping plate 202 increases, the handle 703 needs to apply a larger torque so that when the fixing member 7 rotates, the locking block 704 can slide along the surface of the gear 702 and make a clicking sound, preventing the fixing member 7 from rotating further, limiting the clamping force between the upper clamping plate 201 and the lower clamping plate 202, and avoiding excessive clamping force that could damage the packaging tape.

[0031] After the device is used up, the user can increase the distance between the adjusting member 801 and the slider 4 by rotating the adjusting rod 8, thereby releasing the internal force of the elastic element 705 and increasing the service life of the elastic element 705.

[0032] Preferably, the upper clamping plate 201 and the lower clamping plate 202 are each provided with a rubber plate 9 on their opposite sides to increase the effective contact area between the upper clamping plate 201, the lower clamping plate 202 and the encapsulation surface strip, so that the encapsulation surface strip can be subjected to force evenly.

[0033] Preferably, the upper clamping plate 201 and the lower clamping plate 202 are provided with mounting grooves 10 on their opposite sides. The length direction of the mounting grooves 10 is perpendicular to the direction of movement of the fixed base 2. The rubber plate 9 is inserted into the mounting grooves 10 to facilitate the replacement of worn rubber plates 9.
