[0046] like Figure 1 As shown, the smart card package 10 provided in the embodiment of the present disclosure includes: a carrier 100, a smart card chip 200, a reinforcement 300 and a plastic encapsulation layer 400. The smart card chip 200 is provided with electrode terminals, and the electrode terminals are soldered to the carrier 100 through solder balls 210. The reinforcement 300 is connected to the carrier 100 and is arranged around the smart card chip 200. The plastic encapsulation layer 400 is used to fill and solidify the smart card chip 200 and the reinforcement 300 on the carrier 100.
[0047] Specifically, the carrier 100 represents a packaging substrate or an IC (Integrated Circuit) carrier 100, which is a substrate used to package the smart card chip 200, a bridge used to connect the smart card chip 200 with other components, used to protect, fix and support the smart card chip 200, and can provide a heat dissipation channel for the smart card chip 200.
[0048] Specifically, the smart card chip 200 represents a chip product pasted or embedded in various smart cards 800 such as CPU cards, logic encryption cards, RFID tags, etc. The smart card chip 200 is internally provided with a microprocessor, an input / output device interface and a memory, and can perform data calculation, access control and data storage.
[0049] Specifically, the reinforcement 300 is a component for enhancing the stability and mechanical stress resistance of the overall structure of the smart card package 10. The reinforcement 300 is made of metal materials (eg, steel, aluminum, and copper) or composite materials (eg, carbon fiber and glass fiber).
[0050] Specifically, by providing electrode terminals on the smart card chip 200 and soldering the electrode terminals to the carrier 100 through the solder balls 210, it is no longer necessary to electrically connect the electrode terminals of the smart card chip 200 to the carrier 100 through gold wires, thereby improving the firmness of the electrical connection between the smart card chip 200 and the carrier 100, and soldering the electrode terminals to the carrier 100 with the solder balls 210 will not cause the pins of the smart card chip 200 to be exposed.
[0051] Specifically, by setting the reinforcement 300 around the smart card chip 200 on the carrier 100, and filling and curing the smart card chip 200 and the reinforcement 300 on the carrier 100 through the plastic packaging layer 400, more connection points are provided between the smart card chip 200 and the carrier 100, thereby improving the firmness of the connection between the smart card chip 200 and the carrier 100.
[0052] Optionally, the solder balls 210 of the electrode terminals of the smart card chip 200 are soldered to the carrier 100 by reflow soldering.
[0053] Specifically, reflow soldering (SMT, Surface Mount Technology), also known as surface mount soldering, is a soldering method that directly solders electronic components on the surface of a PCB board to achieve high-density, high-speed, and high-precision mounting and soldering of electronic components.
[0054] Specifically, the solder balls 210 of the electrode terminals of the smart card chip 200 are soldered to the carrier 100 by reflow soldering, so that the firmness of the connection between the smart card chip 200 and the carrier 100 can be improved.
[0055] Optionally, the plastic packaging layer 400 is an adhesive layer filled and cured with an adhesive such as UV glue and used to wrap the chip and the reinforcement 300 .
[0056] The smart card package 10 provided in the embodiment of the present disclosure solders the terminals of the smart card chip 200 to the carrier 100 through the solder balls 210, thereby reducing the risk of disconnection of the electrical connection between the smart card chip 200 and the carrier 100 when the smart card package 10 is subjected to external force. By arranging the reinforcement member 300 around the chip on the carrier 100, and filling and curing the smart card chip 200 and the reinforcement member 300 on the carrier 100 through the plastic sealing layer 400, the risk of the smart card chip 200 falling off the carrier 100 when the smart card package 10 is subjected to external force is reduced. Therefore, the smart card package 10 provided in the embodiment of the present disclosure has a stronger ability to withstand mechanical stress and higher reliability than the smart card package made by the related art.
[0057] like Figure 2 As shown, in some embodiments, the reinforcement member 300 includes a plurality of reinforcement blocks 310 , and the plurality of reinforcement blocks 310 are disposed around the smart card chip 200 .
[0058] Specifically, by configuring the reinforcement 300 as a plurality of reinforcement blocks 310, and configuring the plurality of reinforcement blocks 310 around the smart card chip 200, a plurality of connection points can be provided around the smart card chip 200 for the smart card chip 200 and the carrier 100, so that the plastic encapsulation layer 400 can connect the carrier 100 and the smart card chip 200 more firmly.
[0059] Optionally, the plurality of reinforcement blocks 310 are integrally formed with the carrier plate 100 .
[0060] Specifically, by integrating the plurality of reinforcement blocks 310 with the carrier board 100, the manufactured smart card package 10 can better disperse and resist external mechanical stress, and can simplify the subsequent steps of packaging the smart card chip 200. In this way, the integrity and stability of the smart card package 10 are enhanced.
[0061] Optionally, a plurality of reinforcement blocks 310 are provided separately from the carrier plate 100 .
[0062] Specifically, by separately arranging the reinforcing block 310 and the carrier 100, the production of the carrier 100 and the reinforcing block 310 is facilitated. When the smart card chip 200 is subsequently packaged, the reinforcing block 310 and the carrier 100 can be connected to the carrier 100 by welding or screws. Therefore, by separately arranging the reinforcing block 310 and the carrier 100, the flexibility of the step of packaging the smart card chip 200 can be improved.
[0063] In the disclosed embodiment, by configuring the reinforcement member 300 as a plurality of reinforcement blocks 310 surrounding the smart card chip 200, a plurality of connection points can be provided for the smart card chip 200 and the carrier 100, so that the plastic encapsulation layer 400 connects the carrier 100 and the smart card chip 200 more firmly, thereby improving the reliability of the manufactured smart card package 10.
[0064] like Figure 3 As shown, in some embodiments, the reinforcement member 300 includes a reinforcement ring 320 , and the reinforcement ring 320 is disposed around the smart card chip 200 .
[0065] Specifically, by setting the reinforcement member 300 as a reinforcement ring 320, and setting the reinforcement ring 320 to be sleeved on the smart card chip 200, a connection surface can be provided for the smart card chip 200 and the carrier 100 around the smart card chip 200, so that the plastic packaging layer 400 can connect the carrier 100 and the smart card chip 200 more firmly.
[0066] Optionally, the reinforcement ring 320 and the carrier plate 100 are integrally formed.
[0067] Specifically, by integrating the reinforcement ring 320 with the carrier 100, the carrier 100 can better disperse and resist external mechanical stress, and can simplify the subsequent steps of packaging the smart card chip 200. In this way, the integrity and stability of the smart card package 10 are enhanced.
[0068] Optionally, the reinforcement ring 320 and the carrier plate 100 are provided separately.
[0069] Specifically, by separately arranging the reinforcement ring 320 and the carrier 100, the production of the carrier 100 and the reinforcement ring 320 is facilitated. When the smart card chip 200 is subsequently packaged, the reinforcement ring 320 and the carrier 100 can be connected to the carrier 100 by welding or screws. Therefore, by separately arranging the reinforcement ring 320 and the carrier 100, the flexibility of the step of packaging the smart card chip 200 can be improved.
[0070] In the disclosed embodiment, by configuring the reinforcement member 300 as a reinforcement ring 320 for sleeve-mounting the smart card chip 200, a connection surface can be provided for the smart card chip 200 and the carrier 100, so that the plastic encapsulation layer 400 connects the carrier 100 and the smart card chip 200 more firmly, thereby improving the reliability of the manufactured smart card package 10.
[0071] In some embodiments, the reinforcement member 300 is disposed in a region of the carrier 100 where the mechanical stress tolerance is less than a set threshold.
[0072] Specifically, if the ability of a certain area on the carrier 100 to withstand mechanical stress is less than a set threshold, it indicates that the area is very likely to be damaged when receiving an external force. Therefore, it is necessary to set the reinforcement member 300 in the area of the carrier 100 where the ability to withstand mechanical stress is less than the set threshold. In this way, the ability of the carrier 100 to withstand external forces is improved, the mechanical strength of the carrier 100 is improved, and thus the reliability of the manufactured smart card package 10 is improved.
[0073] like Figure 4 As shown, in some embodiments, a wiring groove 110 is disposed on the carrier 100 , and the smart card chip 200 is disposed in the wiring groove 110 .
[0074] Specifically, the wiring groove 110 is a groove structure opened in the middle of the carrier 100 and having a size matching the size of the smart card chip 200. The size of the wiring groove 110 is larger than the size of the smart card chip 200, and the depth of the wiring groove 110 is smaller than the thickness of the smart card chip 200.
[0075] Specifically, by opening a wiring groove 110 on the carrier 100 and setting the smart card chip 200 in the wiring groove 110, the smart card chip 200 can be connected to the carrier 100 by welding in addition to the bottom surface, and part of the side surface can also be tightly connected to the carrier 100 through the plastic packaging layer 400.
[0076] In the embodiment of the present disclosure, by opening the wiring groove 110 on the carrier 100 and disposing the smart card chip 200 in the wiring groove 110 , the firmness of the connection between the smart card chip 200 and the carrier 100 is further improved.
[0077] like Figure 5 As shown, in some embodiments, a plurality of through holes 120 are disposed in the area where the carrier 100 is connected to the smart card chip 200 , and the plurality of through holes 120 and the solder balls 210 are arranged in a staggered manner.
[0078] Specifically, the through hole 120 is arranged through the thickness direction of the carrier 100 , is located at the bottom of the smart card chip 200 , and is staggered with the electrode terminal of the smart card chip 200 and the solder ball 210 of the carrier 100 .
[0079] Specifically, by opening a plurality of through holes 120 along the thickness direction of the carrier 100 in the area on which the smart card chip 200 is placed, the surface of the smart card chip 200 can be in contact with the external air, and the heat generated by the smart card chip 200 during operation can be transferred to the outside of the smart card package 10 by using the through holes 120, thereby achieving efficient heat dissipation of the smart card chip 200.
[0080] In the embodiment of the present disclosure, a plurality of through holes 120 are provided along the thickness direction of the carrier board 100 in the area where the smart card chip 200 is placed on the carrier board 100 , thereby improving the heat dissipation capability of the smart card chip 200 .
[0081] like Figure 6 As shown, in some embodiments, the smart card package 10 further includes a heat dissipation component 500 . The heat dissipation component 500 is disposed at the bottom of the carrier 100 and abuts against the smart card chip 200 through the through hole 120 .
[0082] Specifically, the heat dissipation component 500 is a component used to ensure that the smart card chip 200 can effectively dissipate the heat generated by the smart card chip 200 when working.
[0083] Specifically, by setting a heat dissipation component 500 at the bottom of the carrier 100 and abutting the heat dissipation component 500 against the smart card chip 200 through the through hole 120, the heat generated by the smart card chip 200 during operation can be absorbed and dissipated to the outside through the heat dissipation surface of the heat dissipation component 500, forming a top-down heat transfer path consisting of the smart card chip 200, the through hole 120 and the heat dissipation component 500, thereby improving the heat dissipation efficiency of the smart card chip 200.
[0084] In the disclosed embodiment, a heat dissipation assembly 500 is disposed at the bottom of the carrier 100 , and the heat dissipation assembly 500 is abutted against the smart card chip 200 through the through hole 120 , thereby improving the heat dissipation efficiency of the smart card chip 200 .
[0085] like Figure 6 As shown, in some embodiments, the heat dissipation assembly 500 includes: a heat conductive member 510 and a first heat dissipation member 520. The plurality of heat conductive members 510 are correspondingly disposed in the plurality of through holes 120. The first heat dissipation member 520 is disposed at the bottom of the carrier 100 and connected to the plurality of heat conductive members 510.
[0086] Specifically, the heat conducting member 510 is a component made of a heat conducting material (eg, heat conducting silicone grease, heat conducting glue or heat conducting metal) and is capable of efficiently transferring and dissipating heat.
[0087] Specifically, the first heat sink 520 is a component that can effectively transfer, dissipate or dissipate the heat generated by the smart card chip 200, such as a heat sink, a heat pipe, and a vapor chamber.
[0088] Specifically, by arranging a heat conductive member 510 in each through hole 120 and connecting the plurality of heat conductive members 510 to the first heat sink 520 arranged at the bottom of the carrier 100, the heat generated by the smart card chip 200 during operation can be transferred downward to the first heat sink 520 through the carrier 100 by means of the through holes 120 and the heat conductive members 510, thereby forming a heat transfer path of the smart card chip 200, the heat conductive member 510 and the first heat sink 520, and the heat transfer path is from top to bottom, thereby improving the heat dissipation efficiency of the smart card chip 200 and achieving the purpose of efficiently dissipating the heat of the smart card chip 200.
[0089] Optionally, a thermally conductive adhesive is used as the thermally conductive member 510, and a heat sink is used as the first heat sink 520. This allows the installation of the heat dissipation component 500 of the smart card package 10 to be completed by injecting the thermally conductive adhesive into the through hole 120 and attaching the heat sink to the thermally conductive adhesive when manufacturing the smart card package 10. This helps to simplify the steps of manufacturing the smart card package 10.
[0090] In the embodiment of the present disclosure, by disposing a heat conductive member 510 in each through hole 120 and connecting the plurality of heat conductive members 510 to a first heat sink 520 disposed at the bottom of the carrier 100, a top-down heat transfer path is formed among the smart card chip 200, the heat conductive member 510 and the first heat sink 520, thereby further improving the heat dissipation efficiency of the smart card chip 200.
[0091] In some embodiments, the smart card package 10 further includes a second heat sink 600 . The second heat sink 600 is disposed on the upper portion of the smart card chip 200 to dissipate heat for the smart card chip 200 .
[0092] Specifically, the second heat sink 600 is a component that can effectively transfer, dissipate or dissipate the heat generated by the smart card chip 200, such as a heat sink, a heat pipe, and a vapor chamber.
[0093] Specifically, by disposing the second heat sink 600 on the upper part of the smart card chip 200, the heat dissipation efficiency of the smart card chip 200 during operation can be improved, the risk of the smart card chip 200 failing to operate due to overheating can be reduced, and the reliability of the smart card package 10 can be improved.
[0094] In some embodiments, the carrier 100 is a PCB circuit board made of FR-4 material.
[0095] Specifically, by using a PCB circuit board made of FR-4 material as the carrier 100 , compared with using a strip as the carrier 100 in the related art, the manufacturing cost of the smart card package 10 can be effectively reduced.
[0096] In some embodiments, the carrier 100 is a PCB circuit board made of insulating thermal conductive material.
[0097] Specifically, by using a PCB circuit board made of insulating thermal conductive material as the carrier 100, the carrier 100 can have high thermal conductivity and good electrical insulation performance. In this way, the low heat dissipation efficiency of the smart card chip 200 during operation caused by the plastic sealing layer 400 being coated on the surface of the smart card chip 200 is overcome.
[0098] like Figure 8As shown, in some embodiments, the smart card 800 includes: a card body 810 and the smart card package 10 as described above. The smart card package 10 is installed in the card body 810 .
