Technical Field

[0040] The electrical connector 3 , the positive electrode conductive part 21 and the negative electrode conductive part 22 can all be made of metal materials such as copper to form an electrical connection.
[0041] According to the capacitor structure 100 of the embodiment of the present invention, by arranging the capacitor structure 100 between the first element and the second element, and connecting the positive conductive part 21 and the negative conductive part 22 connected to the capacitor body 2 to the first element at the same time, the capacitor structure 100 can play a filtering role, and can reduce the distance between the capacitor structure 100 and the first element, thereby improving the filtering performance of the capacitor structure 100, and the part of the first element blocked by the capacitor structure 100 can be connected to the second element through the electrical connection body 3, thereby improving the connection reliability between the two.

[0043] Specifically, the structural body 1 includes three parts, namely a first insulating layer 13, a substrate layer 14 and a second insulating layer 15. The substrate layer 14 is arranged between the first insulating layer 13 and the second insulating layer 15, that is, the first insulating layer 13, the substrate layer 14 and the second insulating layer 15 are arranged in sequence, so that the capacitor structure 100 can form a sandwich structure, and the surfaces of the first insulating layer 13 and the second insulating layer 15 facing away from each other are respectively constructed as a first surface 11 and a second surface 12, that is, the surface of the first insulating layer 13 facing away from the second insulating layer 15 is arranged upward to form the first surface 11, and the surface of the second insulating layer 15 facing away from the first insulating layer 13 is arranged downward to form the second surface 12, and then the first insulating layer 13, the substrate layer 14 and the second insulating layer 15 can be arranged in sequence from top to bottom.
[0044] Among them, the substrate layer 14 can be made of materials such as silicon and quartz, which is used to provide physical support for the capacitor 2 and the electrical connector 3 to ensure the stability and shape of the capacitor structure 100 during manufacturing and use. The first insulating layer 13 and the second insulating layer 15 can be insulating materials such as silicon dioxide and silicon nitride to play an isolation role. The surfaces of the first insulating layer 13 and the second insulating layer 15 facing away from each other are respectively constructed as the first surface 11 and the second surface 12, that is, the first insulating layer 13 and the second insulating layer 15 are respectively arranged on both sides of the capacitor structure 100, so that the first insulating layer 13 and the second insulating layer 15 can separate the electrical connection points at both ends of the capacitor structure 100 to avoid direct contact between them and causing a short circuit, and the first insulating layer 13 can also separate the positive conductive part 21 and the negative conductive part 22 extending to the first surface 11 to avoid direct contact between the positive conductive part 21 and the negative conductive part 22 and causing a short circuit, thereby causing failure of the capacitor structure 100.
[0045] In addition, the first insulating layer 13 and the substrate layer 14 jointly form a accommodating space 16, and the accommodating space 16 has a certain volume and can be used to accommodate the capacitor 2. The capacitor 2 can be disposed in the accommodating space 16 to realize the installation of the capacitor 2 in the capacitor structure 100, and the positive conductive part 21 and the negative conductive part 22 connected to the capacitor 2 can be conveniently extended from the capacitor 2 to the first surface 11, and connected to the first element at the first surface 11, so as to realize the filtering effect of the capacitor structure 100.
[0046] In some embodiments, the substrate layer 14 is formed with a first receiving groove 141 open to the first insulating layer 13, and the first insulating layer 13 is formed with a second receiving groove 131 connected to the first receiving groove 141, a portion of the capacitor body 2 is located in the first receiving groove 141, and another portion of the capacitor body 2 is located in the second receiving groove 131 to be connected to the positive conductive portion 21 and the negative conductive portion 22.
[0047] Specifically, the first accommodating groove 141 and the second accommodating groove 131 can both be used to accommodate the capacitor 2. The first accommodating groove 141 is connected to the second accommodating groove 131 so that a portion of the capacitor 2 can be located in the first accommodating groove 141, and the other portion can be located in the second accommodating groove 131, that is, the capacitor 2 can be extended from the first accommodating groove 141 to the second accommodating groove 131, so as to increase the setting length and setting area of the capacitor 2, thereby increasing the capacitance of the capacitor 2 to enhance the filtering effect of the capacitor structure 100, and the first accommodating groove 141 is set in the substrate layer 14 and is open to the first insulating layer 13, and the second accommodating groove 131 is set in the first insulating layer 13, which can facilitate the connection of the first accommodating groove 141 with the second accommodating groove 131, thereby facilitating the extension of the capacitor 2 from the first accommodating groove 141 to the second accommodating groove 131.

At the same time, at least two first accommodating grooves 141 are separated and connected to the second accommodating groove 131 respectively, so as to avoid interference between the at least two first accommodating grooves 141, resulting in a reduction in the setting length and setting area of the capacitor 2, and it is convenient for the capacitor 2 to pass through at least two first accommodating grooves 141 in sequence. The two ends of the capacitor 2 can extend from the first first accommodating groove 141 and the last first accommodating groove 141 to the second accommodating groove 131 respectively to be connected to the positive conductive portion 21 and the negative conductive portion 22.
[0052] Furthermore, the capacitor body 2 includes at least two capacitor segments 23, that is, the number of the capacitor segments 23 can be two, three or more, so as to increase the capacitance of the capacitor body 2 through the at least two capacitor segments 23, and the at least two capacitor segments 23 are accommodated in at least two first accommodating grooves 141 in a one-to-one correspondence, that is, for each capacitor segment 23, a first accommodating groove 141 can be set to accommodate it, which can improve the reliability of accommodating the capacitor segments 23, that is, the reliability of the setting of the capacitor body 2 and the reliability of the operation of the capacitor body 2 can be improved.

The positive electrode layer 25 and the negative electrode layer 27 are stacked and distributed, and the intermediate insulating layer 26 is arranged between the positive electrode layer 25 and the negative electrode layer 27.

At the same time, the unblocked part of the chip 201 can also be directly connected to the adapter board 202 through the bump 203 to improve the connection reliability between the chip 201 and the adapter board 202, and the bump 203 can be constructed as a Cu / Sn / Cu structure, or as a Cu / Cu structure.
