Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging, and in particular to a film applicator and a film applicator system. Background Technology

[0002] Frame bonding is a common process in chip packaging. For example, in QFN (Quad Flat No-leads Package) copper sheet soldering products, a film needs to be bonded to the chip surface to complete the packaging. A bonding machine is required to apply the film during the frame bonding process.

[0003] In the front-end process before film application, the chip usually needs to be baked. For example, in the front-end process of QFN copper sheet welding products, it needs to withstand a high temperature of 380°C. This will result in more overflow material generated during the molding process remaining on the back of the frame after molding, thus affecting the welding performance of the product on the PCB (circuit board).

[0004] Therefore, how to provide a film applicator that can avoid overflow caused by the high temperature of the preceding process is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0019] The present invention provides a film applicator, comprising an applicator platform, an x-axis motion module, a material gripping mechanism, and an applicator mechanism. The applicator platform is connected to the x-axis motion module, so that during operation, the x-axis motion module drives the applicator platform to move along the x-direction.

[0033] The core of this invention is to provide a film-applying machine. In the prior art, the frame to be film-applied typically comprises a frame substrate, a chip, and welding materials of different materials. These materials result in different coefficients of thermal expansion within the chip, leading to unevenness of the frame substrate after the preceding high-temperature process due to these different coefficients of expansion. During injection molding after film application, insufficient adhesion between the film and the frame substrate under injection pressure causes slight separation during the molding process, resulting in material overflow on the back of the frame.

[0034] The present invention provides a film applicator, comprising an applicator platform, an x-axis motion module, a material gripping mechanism, and an applicator mechanism. The applicator platform is connected to the x-axis motion module, so that during operation, the x-axis motion module drives the applicator platform to move along the x-direction. The material gripping mechanism is located on one side of the applicator mechanism. The applicator mechanism includes an applicator device, a dust removal device located on the side of the applicator device facing the material gripping mechanism, and an air blowing device. The applicator device includes a roller frame, an air supply channel is provided inside the roller frame, an air outlet is provided on the roller frame facing the roller surface, an air inlet is provided on the outer periphery of the roller frame, the air supply channel connects the air inlet and the air outlet, and the air outlet of the air blowing device is positioned facing the air inlet. The air blowing device can at least heat the air inside the air blowing device.

[0035] The air blowing device heats the air inside to blow hot air into the roller frame through the air inlet. This hot air then exits through the air outlet facing the rollers via air delivery channels within the roller frame. During use, the film to be bonded is pressed onto the surface of the chip frame by the rollers, and the air blowing device heats the film bonded to the chip surface. Heating the film effectively increases the bonding strength between the film and the chip frame, allowing it to withstand greater pressure during the molding process and preventing polyester material overflow after molding.

[0036] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a film applicator provided in an embodiment of the present utility model; Figure 2 for Figure 1 A top-view structural diagram; Figure 3 for Figure 1 A frontal view of the structure.

[0039] See Figures 1 to 3 In this embodiment of the utility model, the film applicator includes an applicator platform 1, an x-axis motion module 2, a material gripping mechanism 3, and an applicator mechanism. The applicator platform 1 is connected to the x-axis motion module 2, so that during operation, the x-axis motion module 2 drives the applicator platform 1 to move along the x-direction. The material gripping mechanism 3 is located on one side of the applicator mechanism. The applicator mechanism includes an applicator device, a dust removal device 4 located on the side of the applicator device facing the material gripping mechanism 3, and an air blowing device 6. The applicator device includes a roller frame 5, an air supply channel 51 is provided inside the roller frame 5, an air outlet is provided on the roller surface of the roller frame 5, an air inlet is provided on the outer periphery of the roller frame 5, the air supply channel 51 connects the air inlet and the air outlet, and the air outlet of the air blowing device 6 is provided facing the air inlet. The air blowing device 6 can at least heat the air inside the air blowing device 6.

[0040] The aforementioned film-applying platform 1 is used to carry materials. In this embodiment, it is specifically used to carry and fix the frame to be film-applied. The film-applying platform 1 typically has a bearing surface for carrying and fixing the frame. Specifically, the film-applying platform 1 is connected to the x-axis motion module 2. This x-axis motion module 2 drives the film-applying platform 1 to move along the x-direction. During operation, the x-axis motion module 2 drives the film-applying platform 1 to move along the x-direction, thereby causing the frame to be film-applied to pass through the film-applying mechanism for film application onto its surface. The specific structure of the x-axis motion module 2 can be customized according to actual conditions and is not specifically limited here.

[0041] The aforementioned material gripping mechanism 3 is typically a robotic arm, which transfers the frame to be coated from the material box to the coating platform 1 for transport and coating. In this embodiment, the material box typically includes a material frame 8 and a paper frame 9. The specific structure of these components can be found in existing technology and will not be elaborated upon here.

[0042] The aforementioned film-applying mechanism is used to apply film to the surface of a frame to be filmed. In this embodiment, the film-applying mechanism includes a film-applying device, a dust removal device 4, and an air-blowing device 6. The film-applying device is the main mechanism for performing the film-applying function, while the dust removal device 4 and the air-blowing device 6 are auxiliary film-applying mechanisms. The film-applying device includes a roller frame 5 and rollers mounted on it. During the film-applying process, the film adheres to the surface of the frame to be filmed based on the downward pressure applied by the rollers. In this embodiment, the roller frame 5 functions to fix the rollers, control the downward pressure of the rollers, and allow the rollers to rotate.

[0043] The dust removal device 4 is located on the side of the film application device facing the material gripping mechanism 3. The dust removal device 4 is used to remove dust from the surface of the frame to be applied. Therefore, the film application platform 1 needs to pass through the dust removal device 4 for dust removal during the movement process, and then pass through the film application device for film application. Therefore, the dust removal device 4 needs to be located on the side of the film application device facing the material gripping mechanism 3.

[0044] The aforementioned air blowing device 6 is typically fixed separately to the side of the film-applying device. This air blowing device 6 can at least heat the air inside it, thereby heating the film through the hot air blown from the nozzle to increase its adhesion. Specifically, the air blowing device 6 includes an air outlet. Correspondingly, in this embodiment, an air supply channel 51 is provided inside the roller frame 5, with an air outlet on the roller frame 5 facing the roller and an air inlet on the outer periphery of the roller frame 5. The air supply channel 51 connects the air inlet and the air outlet. In this embodiment, the air outlet of the air blowing device 6 needs to face the air inlet so that the hot air blown by the air blowing device 6 enters the roller frame 5 through the air inlet, is transported through the air supply channel 51, and is blown out from the air outlet to the roller, thus achieving heating of the film at the roller by the air blowing device 6 during film application. In this embodiment, the film-applying device, dust removal device 4, and air blowing device 6 included in the film-applying mechanism typically move synchronously as a whole.

[0045] In this embodiment, a y-axis motion module 7 is typically also provided. Two opposing y-axis motion modules 7 are usually arranged in the x-direction, and the film-applying mechanism is usually located between the two y-axis motion modules 7. This y-axis motion module 7 needs to be connected to the film-applying device, typically to various components of the entire film-applying mechanism, including the film-applying device, dust removal device 4, and air blowing device 6, to control the movement of these components in the y-direction. It should be noted that movement in the y-direction here refers to fine-tuning the components in the y-direction. Because when applying film to the chip surface, the distance between the film edge and the chip edge needs to be considered. When the distances between the two edges of the film and the chip edge are unequal, it will affect the film application and subsequent packaging processes. Therefore, in this embodiment, one function of the y-axis motion module 7 is to fine-tune the position of the film-applying mechanism, at least the film-applying device, in the y-direction. The distance of this fine-tuning is typically no greater than the width of the frame to be applied. The specific structure of the y-axis motion module 7 with fine-tuning function can be set according to the actual situation, and no specific limitation is made here. It can be driven by a servo motor or by other means.

[0046] In this embodiment, the material gripping mechanism 3 can be connected to the y-direction motion module 7, and the material gripping mechanism 3 can move in the y-direction based on the y-direction motion module 7.

[0047] In this embodiment, the support structure of the entire film applicator can be a lifting device to facilitate the adjustment of the height of the film applicator. Specifically, it can adjust the height of different positions of the film applicator to maintain a horizontal position. The specific structure of the lifting device can be set according to the actual situation and is not specifically limited here.

[0048] The film applicator provided in this embodiment uses an air blowing device 6 to heat the air inside it and blow hot air into the roller frame 5 through the air inlet. This hot air is then blown out through the air outlet facing the rollers via the air delivery channel 51 within the roller frame 5. During use, the film to be applied is pressed onto the surface of the chip frame by the rollers, and the air blowing device 6 heats the film bonded to the chip surface. Heating the film effectively increases the bonding strength between the film and the chip frame, allowing it to withstand greater pressure during the molding process and preventing the overflow of polyester material after molding.

[0049] The specific structure of the film applicator provided in this embodiment will be described in detail in the following utility model embodiments.

[0050] Example 2

[0051] Please refer to Figures 4 to 7 , Figure 4 This is a schematic diagram of a specific film-applying mechanism provided in an embodiment of the present utility model; Figure 5 for Figure 4 A top-view structural diagram; Figure 6 for Figure 5 A sectional view; Figure 7 for Figure 4 A frontal view of the structure.

[0052] Unlike the above-described embodiments, this embodiment further defines the specific structures of the air blowing device 6 and the roller frame 5. The remaining details have been described in detail in the above embodiments and will not be repeated here.

[0053] See Figures 4 to 7 In this embodiment of the invention, the air outlet extends into the air delivery channel 51 from the air inlet, and has a preset gap with the interior of the air delivery channel 51. In this embodiment, to ensure that as much hot air as possible is transferred to the rollers, the air outlet of the air blower needs to extend into the air inlet of the roller frame 5 to reach the air delivery channel 51. Since the roller frame 5 may move up and down during operation to cooperate with the film application process, for example, during film application, the roller frame 5 may move downwards to apply downward pressure to the film-to-be-applied frame. To avoid the roller frame 5 applying unnecessary stress to the air blowing device 6 and to prevent damage to the air blowing device 6, especially the air outlet, during operation, the air outlet needs to have a preset gap with the interior of the air delivery channel 51, and to prevent collision between the roller frame 5 and the air outlet during the up-and-down movement of the rollers.

[0054] In this embodiment, air inlets are provided on both opposite sides of the outer periphery of the roller frame 5, and the film application mechanism includes two air blowing devices 6. Each air blowing device 6 is provided on the side of the roller frame 5 where the air inlet is provided, and the air outlet of the air blowing device 6 is oriented toward the corresponding air inlet.

[0055] Specifically, two air blowing devices 6 are symmetrically arranged on opposite sides of the film-applying device, typically one on each side along the y-direction. These two devices blow hot air into the same air delivery channel 51 to ensure temperature uniformity within the channel. This, in turn, ensures the uniformity of temperature at all points where the hot air is blown onto the film, guaranteeing that the hot air exiting the outlet is at the same temperature, thus ensuring uniform heating of the film. In this embodiment, the air blowing devices specifically blow out hot air at approximately 90°C to heat the film.

[0056] Specifically, in this embodiment, the film-applying platform 1 is equipped with a heating device that heats the bearing surface of the platform 1 during operation. The heating device in the film-applying platform 1 heats the bearing surface used to support the frame to be applied, thereby heating the frame and ensuring that the temperature of the film is approximately the same as the temperature of the frame during the application process, thus guaranteeing a firm bond between the film and the frame. This heating device in the film-applying platform 1 can be a thermocouple or other types of heating devices; the specific structure of the heating device is not specifically limited here.

[0057] Specifically, in this embodiment, the bearing surface of the film application platform 1 is provided with vacuum suction holes. To ensure that the film application platform 1 can quickly fix the frame to be applied during the film application process, in this embodiment, the frame to be applied is fixed using vacuum suction holes. Specifically, these vacuum suction holes are located on the bearing surface of the film application platform 1, and are typically arranged in a row on this bearing surface to adsorb the frame to be applied.

[0058] Specifically, in this embodiment, the vacuum suction holes are positioned in the gap regions between adjacent windows in the film-to-be-applied frame. The film-to-be-applied frame typically has multiple windows, each window acting as a core element. Gaps are formed between adjacent windows. In this embodiment, the vacuum suction holes are positioned in these gap regions, allowing them to specifically adhere to these gap regions, thus making the film-applied process more stable. By positioning the vacuum suction holes in these gap regions, the vacuum detection value can be increased to -86.2 kPa.

[0059] The film applicator provided in this embodiment can ensure the uniformity of heating temperature for different areas of the film by using two air blowing devices 6 arranged opposite to each other to blow hot air into the same air delivery channel 51; by setting a heating device on the film applicator platform 1, the adhesion between the film and the chip frame can be further improved; by setting vacuum suction holes in the gap area between the corresponding windows on the film applicator platform 1, the film applicator process can be made more stable.

[0060] The specific structure of the film applicator provided in this embodiment will be described in detail in the following utility model embodiments.

[0061] Example 3

[0062] Please refer to Figures 8 to 9 , Figure 8 This is a schematic diagram of another specific film applicator provided in an embodiment of the present utility model; Figure 9 for Figure 8 A top-view structural diagram.

[0063] Unlike the above-described embodiments, this embodiment further defines the specific structures of the air blowing device 6 and the roller frame 5. The remaining details have been described in detail in the above embodiments and will not be repeated here.

[0064] See Figure 8 as well as Figure 9 In this embodiment of the utility model, the device includes at least two sets of x-axis motion modules 2 and at least two film application platforms 1. Each film application platform 1 corresponds to one of the x-axis motion modules 2, and each film application platform 1 is connected to the corresponding x-axis motion module 2. The film application machine also includes a y-axis motion module 7, which is connected to the film application mechanism through a drive device, so that during operation, the drive device drives the film application mechanism to move along the y-direction across at least two film application platforms 1.

[0065] To improve film application efficiency, this embodiment specifically sets up multiple film application platforms 1 to alternately apply film, thereby increasing efficiency. Specifically, this embodiment includes at least two sets of x-axis motion modules 2 and at least two film application platforms 1, with each film application platform 1 corresponding to a x-axis motion module 2, and each film application platform 1 connected to its corresponding x-axis motion module 2. The film application machine also includes a y-axis motion module 7, which is connected to the film application mechanism via a drive device, enabling the drive device to move the film application mechanism along the y-direction across at least two film application platforms 1 during operation.

[0066] In this embodiment, the film applicator includes at least two sets of x-axis motion modules 2 and at least two film applicator platforms 1. The x-axis motion modules 2 are connected one-to-one with the film applicator platforms 1, enabling the x-axis motion modules 2 to drive the film applicator platforms 1 to move along the x-direction during operation. In this embodiment, multiple film applicator platforms 1 share a single film applicator mechanism for film application; therefore, the film applicator mechanism needs to be able to move a wide range along the y-direction. Simultaneously, during operation, multiple film applicator platforms 1 will alternately move along the x-direction to apply film. Specifically, in this embodiment, the y-axis motion module 7 is used to further enable the film applicator mechanism to move significantly along the y-direction, in addition to fine-tuning the film applicator device along the y-direction.

[0067] Specifically, in this embodiment, a driving device is added between the y-direction motion module 7 and each component of the film-applying mechanism to enable the film-applying mechanism to move significantly along the y-direction. Specifically, the driving device is used to drive each component of the film-applying mechanism to move along the y-direction across at least two film-applying platforms 1, thereby enabling the film to be applied to the frames to be applied to the different film-applying platforms 1.

[0068] In this embodiment, the driving device may include a cylinder connected to the dust removal device 4, and a servo motor connected to the film application device. Since the alignment accuracy of the dust removal device 4 after moving in the y-direction does not need to be very high, it is only necessary to achieve approximate alignment between the dust removal device 4 and each film application platform 1. Therefore, in this embodiment, a cylinder can be used as the driving device for the dust removal device 4 to move in the y-direction, thereby reducing the cost of the film application machine.

[0069] The alignment accuracy of the film-applying device with each film-applying platform 1 after movement in the y-direction is relatively high, requiring precise positioning between the film-applying device and the film-applying platform 1. Therefore, in this embodiment, a servo motor can be used as the driving device for the movement of the film-applying device in the y-direction to ensure sufficient alignment accuracy after movement. It should be noted that in this embodiment, the air-blowing device 6 and the film-applying device usually need to move synchronously, and the air-blowing device 6 usually also needs to be connected to a corresponding driving device for the film-applying device, such as the aforementioned servo motor.

[0070] In this embodiment, multiple film-applying platforms 1 move alternately along the x-direction. After applying film to a frame carried by one film-applying platform 1, the film-applying mechanism moves along the y-direction to an adjacent film-applying platform 1 under the drive of the aforementioned driving device. During the film-applying process on one frame, before the film application is completed, the material handling mechanism 3 can place the next frame to be applied on the surface of another film-applying platform 1, thus improving film-applying efficiency. With only a single film-applying platform 1 (i.e., a single carrier), each frame takes 51 seconds to complete the entire film-applying process, and the UPH (upper hourly output) is typically 70 frames / hour. However, with two film-applying platforms 1 (i.e., a dual-carrier setup), the first frame takes 51 seconds to complete the entire film-applying process, while each subsequent frame only takes 32 seconds, resulting in a UPH of 108 frames / hour, an improvement of 53%.

[0071] The film applicator provided in this embodiment enables the film applicator to move over a wide range by setting up multiple corresponding film applicator platforms 1 and x-axis motion modules 2, and by adding an additional drive device between the y-axis motion module 7 and the film applicator, thereby realizing the simultaneous execution of multiple film preparation processes and improving film applicator efficiency.

[0072] Example 4

[0073] This embodiment also provides a film application system, which includes a film application machine as provided in any of the above utility model embodiments. In addition to the film application machine, it typically requires a power supply component, control components for each component, and other components. The specific components can be customized according to actual needs and are not specifically limited here. The specific details of the film application machine have been described in detail in the above utility model embodiments and will not be repeated here.

[0074] Since the film application system provided in this embodiment includes the film application machine disclosed in the above embodiment, the film application system can effectively increase the bonding strength between the film and the chip frame, so that it can withstand greater pressure during the molding process, thereby avoiding the overflow of polyester material after molding.

[0075] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
