Description

Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing technology, and specifically to a manual opening fixture for packaging structures. Background Technology

[0002] With the advancement of semiconductor manufacturing technology, the requirements for packaging are becoming increasingly stringent, and the cost per unit is rising. It is often necessary to open up some poorly packaged units (single products) (the heat sink is faulty, but the substrate and chip are good and can be reused).

[0003] Traditional delidding methods involve using a blade to cut into the four corner gaps of the unit, thus separating the heatsink from the substrate. Traditional delidding methods have the following problems: 1. The blade cutting into the substrate can easily cause copper leakage. 2. The blade can easily cut your hand when it cuts in. 3. The quality of manually cut pieces cannot be consistent. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a manual opening fixture for packaging structures is provided to solve the problem that traditional opening methods for packaging structures can easily damage the substrate and cut the operator's hands.

[0005] To achieve the above objectives, a manual opening fixture for a packaged structure is provided, comprising: A base having opposing first and second sides; A support platform is formed on the first side of the base. A notch is formed at one end of the support platform facing the second side of the base. A backing plate is installed on the support platform in an adjustable position. The side of the backing plate facing the second side of the base and the platform surface of the support platform enclose a positioning space for embedding the substrate of the encapsulation structure. The heat dissipation cover of the encapsulation structure is aligned with the notch. The base has a guide post on its second side, and the cover is slidably mounted on the guide post. The base is equipped with a driving structure, which drives the cover to slide down. As the cover slides down and presses against the heat dissipation cover, the heat dissipation cover is vertically misaligned with the substrate and sinks into the notch, thereby separating the heat dissipation cover from the substrate.

[0006] Furthermore, the cover has a sliding hole, and the guide post is slidably disposed in the sliding hole.

[0007] Furthermore, the driving structure includes: A bracket is installed on the side of the guide post facing away from the back plate; A screw is rotatably mounted on the bracket. The screw is arranged in the same direction as the guide post. The cover has a threaded hole, which is arranged in the same direction as the sliding hole. The screw is screwed into the threaded hole of the cover.

[0008] Furthermore, the bracket includes two ear plates, which are respectively connected to the upper and lower ends of the guide post. The ear plates have vertical through holes, and the two ends of the screw are rotatably installed in the vertical through holes of the two ear plates.

[0009] Furthermore, a sliding groove is formed on the support platform, and a slider is formed at the bottom of the backing plate. The slider is slidably disposed in the sliding groove, and a translational component for driving the slider is installed in the sliding groove.

[0010] Furthermore, the translation component is an electro-hydraulic push rod.

[0011] Furthermore, the translation component is a lead screw, which is rotatably installed in the slide groove. The lead screw is arranged along the length direction of the slide groove, and the slider has a threaded hole. The lead screw is screwed into the threaded hole of the slider.

[0012] The beneficial effects of this utility model are as follows: The manual opening fixture for the packaging structure forms a positioning space for embedding the substrate of the packaging structure through a support platform and an adjustable backing plate on the platform. The depth of the positioning space is adapted to the thickness of the substrate to accommodate substrates of different thicknesses. By setting a lifting member above the heat dissipation cover of the packaging structure, and using a driving structure to drive the lifting member to press down against the heat dissipation cover without contacting the substrate, the substrate and chip are effectively protected. The heat dissipation cover is peeled off from the substrate without injuring the operator, thus improving the opening efficiency, opening quality and safety of the packaging structure.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Reference Figure 1 and Figure 2 As shown, this utility model provides a manual opening fixture for a packaging structure, including: a base 1, a support platform 2, and a lifting cover 3.

[0019] In this embodiment, the base has a first side and a second side facing each other. A support platform and a hinged cover are integrated on the base.

[0020] Specifically, the support platform 2 is formed on the first side of the base 1. The cover is provided on the second side of the base.

[0021] In this structure, a notch 20 is formed at one end of the support platform 2 facing the second side of the base 1. A backing plate 21 is adjustablely mounted on the support platform 2. A positioning space is formed between the side of the backing plate 21 facing the second side of the base 1 and the platform surface of the support platform 2. The positioning space is for the substrate 41 of the encapsulation structure 4 to be embedded. The heat sink 42 of the encapsulation structure 4 is aligned with the notch 20.

[0022] A guide post 11 is vertically provided on the second side of the base 1. The flip cover 3 is slidably mounted on the guide post 11. The base 1 is equipped with a drive structure 5. The drive structure 5 drives the flip cover 3 to slide down. As the flip cover 3 slides down, it presses against the heat sink cover 42. The heat sink cover 42 is vertically misaligned with the substrate 41 and sinks into the notch 20, thereby separating the heat sink cover 42 from the substrate 41.

[0023] In this embodiment, the drive structure is used to drive the lifting cover to slide up and down. Combined with Figure 1As shown, when using the manual opening fixture for the encapsulation structure of this utility model, the encapsulation structure is set vertically, and the substrate of the encapsulation structure is embedded in the positioning space, while the substrate is attached to the second side of the backing plate facing the base. At this time, the heat sink cover of the encapsulation structure is aligned with the notch on the support platform. The drive structure is activated to lower the cover lifting component, so that the cover lifting component presses against the top of the heat sink cover. The drive structure continues to drive the cover lifting component downward, and the cover lifting component presses downward against the heat sink cover (applying downward pressure F to the heat sink cover), thereby causing the heat sink cover and the substrate to be misaligned vertically, and the bottom of the heat sink cover sinks and is embedded in the notch, peeling the heat sink cover off the substrate.

[0024] In this embodiment, the guide post can be a square post or a cylinder. The cover is elongated. Correspondingly, the cover 3 has a sliding hole. The guide post 11 slides in the sliding hole. The sliding hole is located in the middle of the cover, and one end of the cover is used to press down against the heat dissipation cover of the encapsulation structure.

[0025] In a preferred embodiment, the drive structure 5 includes a bracket and a screw 52.

[0026] Specifically, the bracket is installed on the side of the guide post 11 facing away from the back plate 21. The screw 52 is rotatably mounted on the bracket. The screw 52 is aligned with the guide post 11. The flip cover 3 has a threaded hole. The threaded hole is aligned with the sliding hole. The screw 52 is screwed into the threaded hole of the flip cover 3.

[0027] In this embodiment, the bracket includes two ear plates 511. The two ear plates 511 are respectively connected to the upper and lower ends of the guide post 11. The ear plates 511 have vertical through holes. The two ends of the screw 52 are rotatably installed in the vertical through holes of the two ear plates 511.

[0028] The upper and lower ends of the screw are respectively mounted in the vertical through holes of the ear plate via bearings. A handwheel is installed at the upper end of the screw. When the operator is peeling the substrate and heat sink of the package structure, he can temporarily fix the substrate in the positioning space with one hand, and turn the handwheel with the other hand to drive the lifting device to press down the heat sink, thereby conveniently, quickly and efficiently peeling the heat sink from the substrate.

[0029] In this embodiment, a groove is formed on the support 2. A slider is formed on the bottom of the backing plate 21. The slider is slidably disposed in the groove. A translation member is installed in the groove. The translation member is used to drive the slider to move along the length direction of the groove.

[0030] In a preferred embodiment, the groove is a dovetail groove. Accordingly, the shape and size of the slider's cross-section are adapted to the shape and size of the groove's cross-section.

[0031] In some embodiments, the translation component is an electro-hydraulic actuator. Preferably, the electro-hydraulic actuator is arranged along the length of the slide groove. The fixed end of the electro-hydraulic actuator is connected to the groove wall at one end of the slide groove, and the telescopic end of the electro-hydraulic actuator is connected to the slider. The position of the slider in the slide groove is adjusted by extending and retracting the electro-hydraulic actuator.

[0032] In other embodiments, the translation component is a lead screw. The lead screw is rotatably mounted in a slide groove. The lead screw is positioned along the length of the slide groove. The slide block has a threaded hole. The lead screw is screwed into the threaded hole of the slide block. To improve the position adjustment efficiency of the backing plate, a motor is mounted on the support platform. The motor is driven and connected to the lead screw. The operator controls the rotation of the motor via a controller connected to the motor to rotate the lead screw, causing the backing plate to slide along the length of the slide groove, adjusting the distance between the backing plate and the notch, so that the depth of the positioning space is adapted to the thickness of the substrate.

[0033] This utility model discloses a manual cap-opening fixture for packaging structures. It creates a positioning space for embedding the substrate of the packaging structure by using a support platform and an adjustable backing plate on the platform. The depth of the positioning space is adapted to the thickness of the substrate to accommodate substrates of different thicknesses. A lifting mechanism is provided above the heat sink cover of the packaging structure. A driving structure drives the lifting mechanism to press the heat sink cover downwards without contacting the substrate, effectively protecting the substrate and chip. The heat sink cover is then peeled off from the substrate without injuring the operator, improving the opening efficiency, opening quality, and safety of the packaging structure.

[0034] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
