Description

Technical Field

[0001] This utility model belongs to the technical field of advanced packaging material processing equipment, specifically relating to an advanced packaging material slicing tool. Background Technology

[0002] Advanced packaging is a concept relative to traditional packaging. Traditional packaging typically refers to the process of first cutting a wafer into individual chips and then packaging them. It mainly includes system-in-package (SIIP), dual in-line package (DIP), small outline package (SAIP), small outline transistor (SAPT), transistor outline (TEPT), square flat package (SFP), square flat leadless package (SFP), and ball grid array (BGA) packages. Traditional packaging primarily uses lead frames as a carrier and employs wire bonding for interconnection. Driven by market demand, traditional packaging has continuously innovated and evolved, resulting in various new packaging structures. As the requirements for high speed, miniaturization, system integration, and low cost of electronic products and equipment continue to increase, the limitations of traditional packaging are becoming increasingly prominent. Advanced packaging represents the most cutting-edge packaging forms and technologies. Currently, packaging with flip-chip structures, wafer-level packaging, 2.5D packaging, and 3D packaging are considered to fall under the category of advanced packaging.

[0003] However, existing slicing tools require high precision to ensure accuracy during the cutting process, and they need to be replaced frequently. At the same time, when slicing advanced packaging materials, the slicing effect is not good, and the material is easily not cut through or the slicing edge is not neat. Utility Model Content

[0004] The purpose of this utility model is to provide an advanced packaging material slicing tool to solve the problems mentioned in the background art. In order to ensure accuracy during the cutting process, the existing slicing tools have high precision requirements and high replacement frequency. At the same time, when slicing advanced packaging materials, the slicing effect is not good, and the material is easy to be cut without being cut and the slicing edge is not neat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an advanced packaging material slicing tool, including a spindle;

[0006] A mounting body is provided at the top of the spindle, and a cutting tool body is provided inside the mounting body;

[0007] A first dicing blade is provided at the top of the dicing tool body, a second dicing blade is provided at the rear side of the first dicing blade, and a third dicing blade is provided at the rear side of the second dicing blade.

[0008] Preferably, the first dicing blade, the third dicing blade, and the left and right sides of the second dicing blade are respectively provided with snap-fit ​​grooves, and the first dicing blade, the second dicing blade, and the third dicing blade are snapped together by a 60-degree offset from each other through the snap-fit ​​grooves.

[0009] Preferably, a limiting groove is provided at the outer position of the first and third dicing blades, and the dicing blade body is installed and fixed to the mounting body through the limiting groove.

[0010] Preferably, the first, second, and third dicing blades are elliptical in shape, and chip removal grooves are provided at the top positions on both sides of the first, second, and third dicing blades.

[0011] Preferably, a limiting groove gasket is provided at the outer position of the first and third dicing blades, and a snap-fit ​​gasket is provided at the left and right sides of the second dicing blade.

[0012] Preferably, a positioning plate is provided at the bottom of the mounting body, and the positioning plate is welded to the spindle. A mounting plate is provided at the top of the mounting body, and a fixing hole is provided at the top of the spindle. The mounting plate is fixedly connected to the spindle by fixing bolts and fixing holes.

[0013] Preferably, a limiting block is provided on the inner side of the positioning plate and the mounting plate, and the limiting block is fixedly installed in the limiting groove on the outer side of the cutting tool body.

[0014] Preferably, the first, second, and third dicing blades are provided with pin holes arranged in a circular array inside, the positioning plate and the mounting plate are provided with positioning holes inside, and the mounting plate is provided with pins on the outside. The mounting body positions the internal blades through the positioning holes, pin holes, and pins.

[0015] Compared with the prior art, this utility model provides an advanced packaging material slicing tool, which has the following beneficial effects:

[0016] 1. The dicing tool body is equipped with a first dicing blade, a second dicing blade, a third dicing blade, a locking groove, a limiting groove, a chip removal groove, a limiting groove gasket, and a locking gasket. These three blades are interlocked at a 60-degree angle via locking grooves. This arrangement allows different dicing blades to act sequentially on the material when dicing advanced packaging materials, creating a continuous and multi-angle cutting force. Compared to a single dicing blade, this significantly enhances the dicing capability, enabling easier and more accurate material dicing, improving dicing quality, and resulting in cleaner dicing edges. The dicing tool body is fixed to the mounting body via the limiting groove, ensuring that the tool will not easily shake or shift during high-speed rotation, enhancing the overall stability of the tool, thereby improving machining accuracy and extending tool life. The first dicing blade... The second and third dicing blades adopt an elliptical structure. This shape provides a more reasonable cutting angle during the dicing process, reduces cutting resistance, and improves cutting efficiency. At the same time, chip removal grooves are set at the top of both sides of the dicing blades. During the dicing process, the generated chips can be discharged around the blades in a timely manner through the chip removal grooves, avoiding chip accumulation and adverse effects on the dicing effect, and ensuring continuous and efficient operation of the blades. Limiting groove shims are set on the outer side of the first and third dicing blades, and snap-fit ​​shims are set on the left and right sides of the second dicing blade. These shims can fill the small gaps between the dicing blades and between the dicing blades and the mounting body, buffering the vibration and impact of the blades during operation, further enhancing the stability of the connection between various components, ensuring that the blade structure will not loosen during long-term use, and maintaining the stability of the blade performance.

[0017] 2. The mounting plate, mounting plate, fixing holes, fixing bolts, and limit blocks are used to precisely fix the relative position between the mounting body and the spindle. This provides a stable foundation for the installation of subsequent components. The welded connection method has high strength and stability, capable of withstanding the enormous forces generated by the tool during high-speed rotation and cutting, ensuring that the entire tool system will not loosen or shift during operation, thus improving machining accuracy and equipment reliability. The mounting plate on top of the mounting body is fixedly connected to the spindle via fixing bolts and fixing holes on the top of the spindle. This bolted connection method not only simplifies installation and operation but also makes disassembly very convenient when tool maintenance or component replacement is required. Personnel can quickly remove the mounting plate from the spindle to inspect, repair, or replace internal tools or other components, greatly shortening equipment maintenance time and improving equipment efficiency. The limiting blocks on the inner side of the positioning plate and mounting plate are fixed to the limiting groove on the outer side of the dicing tool body. This structure can accurately position the dicing tool body axially and circumferentially. During installation, the cooperation between the limiting blocks and the limiting grooves ensures that the dicing tool body is accurately installed in the predetermined position, guaranteeing the cutting position accuracy of the tool. At the same time, when the tool is working, this limiting structure can restrict the displacement and shaking of the dicing tool body, improve the stability of the tool and the cutting quality, and effectively avoid machining errors caused by tool position deviation.

The first dicing blade 11, the second dicing blade 12, and the third dicing blade 13 are then interlocked together at a 60-degree angle using the snap-fit ​​groove 19, forming a complete cutting tool section. During the snap-fit ​​process, a tight snap-fit ​​is ensured. Simultaneously, limiting groove gaskets 14 are installed on the outer sides of the first dicing blade 11 and the third dicing blade 13, and snap-fit ​​gaskets 15 are installed on the left and right sides of the second dicing blade 12 to further enhance the stability of the connection between the dicing blades. The mounting plate 4... The outer pin 5 passes through the positioning hole 6 inside the positioning plate 3 and the mounting plate 4, and cooperates with the pin holes 17 arranged in a ring array inside the first dicing blade 11, the second dicing blade 12 and the third dicing blade 13 to accurately position the internal blades and ensure that the blades are installed correctly. After the dicing work is completed, turn off the power of the equipment and clean the dicing blades to remove residual debris and impurities from the blade surface. Regularly check the wear of the dicing blades, such as whether there is wear or damage in the snap-fit ​​groove 19, the limit groove 16 and other parts.

At the same time, check whether the connecting parts, such as the fixing bolts 8 and the pins 5, are loose. If they are loose, tighten them in time to ensure the stability of the blade installation.

[0036] like Figure 1 and Figure 3-5As shown, a first dicing blade 11 is provided at the top of the dicing tool body 10, a second dicing blade 12 is provided at the rear of the first dicing blade 11, and a third dicing blade 13 is provided at the rear of the second dicing blade 12.

A limiting groove 16 is provided on the outer side of the blade 13. The cutting tool body 10 is installed and fixed to the mounting body 1 through the limiting groove 16. The first dicing blade 11, the second dicing blade 12 and the third dicing blade 13 are elliptical structures.

Limiting groove gaskets 14 are provided on the outer side of the first dicing blade 11 and the third dicing blade 13. Snap-fit ​​gaskets 15 are provided on the left and right sides of the second dicing blade 12.

[0037] Preferably, the dicing tool body 10 is provided with a first dicing blade 11, a second dicing blade 12, and a third dicing blade 13, which are interlocked at a 60-degree angle through a locking groove 19. This arrangement allows different dicing blades to act on the material sequentially when dicing advanced packaging materials, forming a continuous and multi-angle cutting force. Compared with a single dicing blade, this greatly enhances the dicing ability, enabling easier and more accurate dicing of materials, improving dicing quality, and making the dicing edges neater. The dicing tool body 10 is fixed to the mounting body 1 through a limiting groove 16, ensuring that the tool will not easily shake or shift during high-speed rotation, enhancing the overall stability of the tool, thereby improving processing accuracy and extending the tool's service life. The first dicing blade 11, the second dicing blade 12, and the third dicing blade 13 adopt an elliptical structure. This structure provides a more reasonable cutting angle during the dicing process, reduces cutting resistance, and improves cutting efficiency. Simultaneously, chip removal grooves 18 are provided at the top of both sides of the dicing blade. During the dicing process, the generated chips can be promptly discharged through the chip removal grooves around the blade, preventing chip accumulation from adversely affecting the dicing effect and ensuring continuous and efficient blade operation. Limiting groove shims 14 are provided on the outer sides of the first dicing blade 11 and the third dicing blade 13, and snap-fit ​​shims 15 are provided on the left and right sides of the second dicing blade 12. These shims can fill the tiny gaps between the dicing blades and between the dicing blade and the mounting body, buffering the vibration and impact of the blade during operation, further enhancing the stability of the connection between various components, ensuring that the blade structure will not loosen during long-term use, and maintaining the stability of the blade performance.

[0038] like Figure 1 and Figure 2As shown, a positioning plate 3 is provided at the bottom of the mounting body 1, and the positioning plate 3 is welded to the spindle 2. A mounting plate 4 is provided at the top of the mounting body 1, and a fixing hole 9 is provided at the top of the spindle 2. The mounting plate 4 is fixedly connected to the spindle 2 by fixing bolts 8 and fixing holes 9. A limit block 7 is provided on the inner side of the positioning plate 3 and the mounting plate 4. The limit block 7 is installed and fixed to the outer limit groove 16 of the cutting tool body 10.

[0039] Preferably, the positioning plate 3 at the bottom of the mounting body 1 is welded to the spindle 2, ensuring precise fixation of the relative position between the mounting body 1 and the spindle 2. This provides a stable foundation for the installation of subsequent components. The welded connection method has high strength and stability, capable of withstanding the enormous forces generated by the tool during high-speed rotation and cutting, ensuring that the entire tool system will not loosen or shift during operation, thus improving machining accuracy and equipment reliability. The mounting plate 4 at the top of the mounting body 1 is fixedly connected to the spindle 2 via fixing bolts 8 and fixing holes 9 at the top of the spindle 2. This bolted connection method not only simplifies installation and operation but also makes disassembly very convenient when tool maintenance or component replacement is required. Maintenance personnel can quickly remove the mounting plate 4 from the spindle. 2. The internal cutting tools or other components can be disassembled for inspection, repair, or replacement, greatly shortening the equipment maintenance time and improving the equipment's efficiency. The limiting block 7 set on the inner side of the positioning plate 3 and the mounting plate 4 is installed and fixed with the limiting groove 16 on the outer side of the cutting tool body 10. This structure can accurately position the cutting tool body 10 axially and circumferentially. During installation, the cooperation between the limiting block 7 and the limiting groove 16 can ensure that the cutting tool body 10 is accurately installed in the predetermined position, ensuring the cutting position accuracy of the tool. At the same time, when the tool is working, this limiting structure can restrict the displacement and shaking of the cutting tool body 10, improve the stability of the tool and the cutting quality, and effectively avoid processing errors caused by tool position deviation.

[0040] like Figure 1-5 As shown, the first dicing blade 11, the second dicing blade 12 and the third dicing blade 13 are provided with pin holes 17 in a circular array inside, the positioning plate 3 and the mounting plate 4 are provided with positioning holes 6 inside, and the mounting plate 4 is provided with pins 5 outside. The mounting body 1 positions the internal blades through the positioning holes 6, pin holes 17 and pins 5.

They are positioned by the engagement of pins 5 on the outside of the mounting plate 4. This design can achieve precise positioning of the internal blades in the circumferential and radial directions. The ring array of pin holes 17 can provide multiple positioning reference points for the blades, so that the blades can more accurately determine their angular positions during installation, ensuring the relative positional accuracy between the blades, ensuring the cutting accuracy and stability of the blades in the process of cutting materials, and improving the processing quality. Through the cooperation of positioning holes 6, pin holes 17, and pins 5, the mounting body 1 is tightly connected to the internal dicing blades. The pins 5 inserted into positioning holes 6 and pin holes 17 can effectively limit the relative movement between the components, enhance the integrity and stability of the entire blade structure. Under the condition of high-speed rotation of the blades and bearing large cutting forces, this positioning structure can prevent the dicing blades from shifting or loosening, ensure that the blade system can work stably and reliably, and extend the service life of the blades.
