Description

Technical Field

[0001] This utility model belongs to the field of semiconductor integrated circuit manufacturing technology and relates to a tape reel. Background Technology

[0002] Wafer Level Chip Scale Packaging (WLCSP) is a wafer-level chip packaging method. Unlike traditional chip packaging methods (which involve dicing and then packaging and testing, increasing the original chip size by at least 20%), WLCSP first packages and tests on the entire wafer, and then dices it into individual chip units. The packaged volume is equal to the original size of the bare die of the chip unit. This not only significantly reduces the size of memory modules, but also meets the high-density requirements of mobile devices for space, further improving the speed and stability of data transmission.

[0003] In wafer-level packaging (WLP) processes, chip units are first placed onto carrier tape using a tape and reel machine. The chips are then sealed by heating the carrier tape with a soldering iron. Finally, the carrier tape is wound onto an anti-static reel for delivery to the customer. However, currently used reels lack effective securing methods, resulting in a high rate of chip detachment during automatic winding. This leads to feeding failures and frequent rework, reducing production efficiency.

[0004] Therefore, how to provide a tape reel to prevent the tape from coming out of the insert groove and avoid repeated rework of the tape winding has become an important problem that needs to be solved by those skilled in the art.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application.

[0056] Please see Figure 1 The diagram shows a structural schematic of a tape reel, which is a spliced ​​type, meaning that two reels 101 are spliced ​​together by a locking buckle 102. Please refer to [link / reference]. Figure 2 Displayed as Figure 1 The side view of the structure shown shows that after splicing, a diamond-shaped groove 103 is formed between the two discs 101, which is used for embedding and fixing the front end of the braid. The diamond-shaped groove 103 can accommodate the flatness of braids of different thicknesses when manually threaded. However, the internal space of the diamond-shaped groove 103 is large and the overall thickness of the braided product is relatively thin. After the front end of the first round of braid is embedded in the diamond-shaped groove 103, there is no effective way to fix it. When the machine automatically rotates and winds the subsequent rounds, there is a high proportion of abnormal pull-out, which easily causes threading failure. Repeated rework is often required, resulting in a decrease in production efficiency.

[0057] The applicant has improved the structure of the tape reel by adding a set of limiting posts in the middle of the slot of the spliced ​​reel. This reduces the movement space of the front tape in the diamond-shaped slot, causing the tape, slot, and limiting posts to interfere with each other. This increases the overall frictional resistance between the tape and the slot, thus solving the problem that the front end of the first loop of tape will come out of the slot due to insecure fixing after being embedded in the slot, and will fall out of the slot during the subsequent automatic rotation and winding of the machine.

[0067] Specifically, the tape reel further includes a through-shaft hole 207, an embedding groove, a first limiting post 2010, and a second limiting post 2011. The through-shaft hole 207 includes a first through-shaft hole 2071 and a second through-shaft hole 2072 disposed opposite to each other.

The embedding groove includes a first embedding groove 2010 disposed opposite to each other. 8 and the second embedding groove 209, the first embedding groove 208 is located in the first boss 203 and extends along the radial direction of the first boss 203 to the side of the first boss 203, the second embedding groove 209 is located in the second boss 204 and extends along the radial direction of the second boss 204 to the side of the second boss 204, the first limiting post 2010 is located at the bottom of the first embedding groove 208, and the second limiting post 2011 is located at the bottom of the second embedding groove 209.

[0068] For details, please refer to Figure 7 The diagram shows the working state of the tape reel of this utility model. The first limiting post 2010 and the second limiting post 2011 are used to increase the mutual interference with the tape 2012 inserted into the embedding groove. Figure 7 The dashed arrow shown indicates the traction direction of the braided tape 2012. That is, the first limiting post 2010 and the second limiting post 2011 increase the contact area between the braided tape disc and the braided tape 2012, increase the resistance experienced by the braided tape 2012, strengthen the fixation of the braided tape 2012, thereby reducing the probability of the braided tape 2012 coming out after entering the embedding groove of the reel, improving the success rate of the braided tape 2012 winding, and avoiding repeated rework of the braided tape 2012 winding.

[0069] As an example, there are multiple embedding slots, which are evenly distributed around the through-hole to facilitate the insertion of the tape 2012. In this embodiment, there are three embedding slots.

[0070] As an example, the height H1 of the first limiting post 2010 is less than the depth H2 of the first boss 203, and the height H3 of the second limiting post 2011 is less than the depth H4 of the second boss 204, so as to ensure that the first baffle 201 and the second baffle 202 can be snapped together.

[0071] As an example, the longitudinal section of the first embedded groove 208 is an inverted trapezoid, and the longitudinal section of the second embedded groove 208 is also an inverted trapezoid, so that the first limiting post 2010 and the second limiting post 2011 can be disposed at the bottom of the first embedded groove 208 and the second embedded groove 208.

[0072] As an example, anti-slip pads are provided on the side walls of the first limiting post 2010 and the second limiting post 2011, which can further increase the friction between the first limiting post 2010, the second limiting post 2011 and the braided tape 2012, increase the resistance to the braided tape 2012 inserted into the embedding groove, enhance the fixation of the braided tape 2012, and thus prevent the braided tape 2012 from coming out of the embedding groove.

[0073] As an example, the first baffle 201 is provided with a first viewing opening 2013, and the second baffle 202 is provided with a second viewing opening 2014. The first viewing opening 2013 and the second viewing opening 2014 facilitate the operator to observe the condition of the tape 2012 when it is being wound up.

[0074] As an example, there are multiple first transparent openings 2013, which are evenly distributed around the first boss 203. There are multiple second transparent openings 2014, which are evenly distributed around the second boss 204. In this embodiment, there are 3 first transparent openings 2013 and 3 second transparent openings 2014.

[0075] As an example, a scale 2015 is provided on the side of the first baffle 201 away from the second baffle 202. The scale 2015 is located on one side of the first viewing opening 2013. The scale 2015 makes it easy for the operator to observe the length of the wound tape on the reel.

[0076] For example, please refer to Figure 8 The image shows another structural side view of the tape reel of this utility model. The outer peripheral region of the first baffle 201 is thicker than the inner peripheral region, and the outer peripheral region of the second baffle 202 is thicker than the inner peripheral region, which makes the tape reel stand more stably vertically and facilitates the movement and storage of the tape reel.

[0077] As an example, a plurality of fixing notches 2016 are provided on the outer edge of the first baffle 201. The plurality of fixing notches 2016 are evenly distributed along the outer edge of the first baffle 201. The fixing notches 2016 are used to fix the free end of the braided tape 2012 to prevent the braided tape that has been wound from becoming loose and messy. In addition, the design of the plurality of fixing notches 2016 ensures that the free end of the braided tape 2012 can be firmly fixed at any position on the outer edge of the first baffle 201. In this embodiment, the number of fixing notches 2016 is 3.

[0078] In summary, the tape reel of this utility model includes a first baffle and a second baffle arranged opposite to each other, a through hole, an embedding groove, a first limiting post, and a second limiting post. The first baffle has a first protrusion on the side near the second baffle, and the second baffle has a second protrusion on the side near the first baffle. The first protrusion has a locking interface, and the second protrusion has a locking tab that engages with the locking interface. The through hole includes a first through hole and a second through hole. The first through hole is located at the center of the first protrusion and penetrates through it, and the second through hole is located at the center of the second protrusion and penetrates through it.
