Referring to FIG. 1 to FIG. 6, a first embodiment of the present disclosure provides a laterally placed capacitor package assembly S (such as a horizontally placed capacitor package assembly) configured to be laterally (such as horizontally) disposed on a circuit substrate P, which includes a wound capacitor package structure 1 and a capacitor supporting structure 2 (such as a capacitor carrying structure or a capacitor holding structure).

Firstly, referring to FIG. 1 and FIG. 2, the wound capacitor package structure 1 includes a wound assembly 11, a conductive assembly 12 and a package assembly 13. More particularly, the wound assembly 11 includes a wound positive conductive foil 111, a wound negative conductive foil 112 and two wound separators 113 (such as two insulating pieces), the conductive assembly 12 includes a first conductive pin 121 electrically contacting the wound positive conductive foil 111 and a second conductive pin 122 electrically contacting the wound negative conductive foil 112 (FIG. 1 shows that the first conductive pin 121 and the second conductive pin 122 have not been flattened), and the wound assembly 11 is disposed inside or enclosed by the package assembly 13.

For example, referring to FIG. 1 and FIG. 2, the wound positive conductive foil 111 and the wound negative conductive foil 112 can be conductive foils made of any conductive material, and the wound separator 113 can be an insulating paper or insulating foil containing a dipping or impregnated material such as a conductive polymer. Furthermore, one of the two wound separators 113 can be disposed between the wound positive conductive foil 111 and the wound negative conductive foil 112, and one of the wound positive conductive foil 111 and the wound negative conductive foil 112 can be disposed between the two wound separators 113 (for example, FIG. 1 shows that the wound positive conductive foil 111 is disposed between the two wound separators 113). Moreover, the first conductive pin 121 includes a first embedded portion 1211 accommodated inside the package assembly 13 and a first exposed portion 1212 exposed outside the package assembly 13 (for example, FIG. 2 shows that a part of the first exposed portion 1212 has been flattened), and the second conductive pin 122 includes a second embedded portion 1221 accommodated inside the package assembly 13 and a second exposed portion 1222 exposed outside the package assembly 13 (for example, FIG. 2 shows that a part of the second exposed portion 1222 has been flattened). In addition, the package assembly 13 includes a package casing 131 (such as an aluminum casing or a casing made of any type of material) configured to accommodate the wound assembly 11 and a bottom sealing structure 132 disposed inside the package casing 131 (such as an insulating rubber body, an insulating silicone body or an insulating epoxy body that can be surroundingly pressed by the package casing 131) to cooperate with the package casing 131, and the package assembly 13 can be completely enclosed by the package casing 131 and the bottom sealing structure 132. However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

Moreover, referring to FIG. 2 and FIG. 3, the capacitor supporting structure 2 includes a supporting portion 21 (such as a carrying portion or a holding portion) configured to support or carry the wound capacitor package structure 1 and a plurality of positioning portions 22 extending outward from the supporting portion 21. For example, the supporting portion 21 of the capacitor supporting structure 2 has an accommodating space 21001 that can be formed as a semi-arc shape or any shape that can conform to the shape of the package casing 131, and a portion of the package assembly 13 of the wound capacitor package structure 1 can be accommodated in the accommodating space 21001 of the supporting portion 21. In addition, the package casing 131 of the package assembly 13 of the wound capacitor package structure 1 has an outer surface 13100, and most of the outer surface 13100 of the package casing 131 is exposed outside the capacitor supporting structure 2 which will facilitate heat dissipation of the wound capacitor package structure 1. It should be noted that the wound capacitor package structure 1 can be carried and supported by a predetermined strength through the capacitor supporting structure 2, so that the wound capacitor package structure 1 can be configured to effectively resist vibration. In other words, the first conductive pin 121 and the second exposed portion 1222 of the wound capacitor package structure 1 are not easily separated from the electrical connection relationship with the circuit substrate P due to external vibrations. However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

More particularly, for example, referring to FIG. 3, FIG. 4 and FIG. 6, when the capacitor supporting structure 2 is configured to be disposed on the circuit substrate P, the supporting portion 21 of the capacitor supporting structure 2 can be configured to pass through the circuit substrate P, and the plurality of positioning portions 22 of the capacitor supporting structure 2 can be configured to be disposed on the circuit substrate P for limiting or restrict a position of the capacitor supporting structure 2 relative to the circuit substrate P. However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

More particularly, for example, referring to FIG. 3, FIG. 4 and FIG. 5, when the wound capacitor package structure 1 is configured to be laterally or horizontally disposed on the capacitor supporting structure 2, the first exposed portion 1212 of the first conductive pin 121 and the second exposed portion 1222 of the second conductive pin 122 can laterally or horizontally extend from the package assembly 13 without bending (i.e., do not bend the first exposed portion 1212 and the second exposed portion 1222) and be electrically connected to the circuit substrate P. It should be noted that the first exposed portion 1212 of the first conductive pin 121 and the second exposed portion 1222 of the second conductive pin 122 are electrically connected to the circuit substrate P without bending, the wound capacitor package structure 1 can provide electrical characteristics that meet market demand (or customer demand). However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

More particularly, for example, referring to FIG. 3, FIG. 4 and FIG. 6, when the capacitor supporting structure 2 is configured to be disposed on the circuit substrate P, the plurality of positioning portions 22 of the capacitor supporting structure 2 can be configured to be disposed on an upper surface or a lower surface of the circuit substrate P. That is to say, the user can selectively or optionally place the laterally placed capacitor package assembly S laterally on the upper surface or the lower surface of the circuit substrate P according to different requirements. However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

More particularly, for example, referring to FIG. 2, FIG. 3 and FIG. 6, when the capacitor supporting structure 2 is configured to be disposed on the circuit substrate P, the plurality of positioning portions 22 of the capacitor supporting structure 2 can be configured to be respectively fixed or positioned on a plurality of positioning areas P101 of the circuit substrate P, and each of the plurality of positioning areas P101 can be a recessed area (as shown in FIG. 2, the present disclosure takes as an example that each of the positioning areas P101 can be a recessed area) or a planar area (such as an area flush with the upper surface of the circuit board P). For example, when the plurality of positioning portions 22 of the capacitor supporting structure 2 are configured to be respectively fixed in the plurality of recessed areas (i.e., the plurality of positioning areas P101) of the circuit substrate P, the position of the capacitor supporting structure 2 relative to the circuit substrate P can be limited through cooperation of the positioning portions 22 and the recessed area (i.e., the plurality of positioning areas P101). However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

More particularly, for example, referring to FIG. 2, FIG. 3 and FIG. 4, when the capacitor supporting structure 2 is configured to be disposed on the circuit substrate P, the supporting portion 21 of the capacitor supporting structure 2 can be configured to pass through a strip-shaped opening P102 (or an elongated opening) of the circuit substrate P. It should be noted that the plurality of positioning portions 22 of the capacitor supporting structure 2 can be arranged along two long sides or two short sides of the strip-shaped opening P102 of the circuit substrate P (as shown in FIG. 2, the present disclosure takes as an example that the positioning portions 22 are arranged along the two long sides of the strip-shaped opening P102 of the circuit substrate P), and the plurality of positioning portions 22 of the capacitor supporting structure 2 can be separated from each other and correspond to each other, or can be connected with each other to form a single positioning portion (FIG. 2 illustrates an example in which the plurality of positioning portions 22 are separate from each other and correspond to each other). However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

More particularly, for example, referring to FIG. 2, FIG. 3 and FIG. 5, when the wound capacitor package structure 1 is configured to be laterally or horizontally disposed on the capacitor supporting structure 2, a first flat area 12120 of the first exposed portion 1212 of the first conductive pin 121 and a second flat area 12220 of the second exposed portion 1222 of the second conductive pin 122 can respectively and electrically contact a first soldering area P103 and a second soldering area P104 of the circuit substrate P by soldering. It should be noted that the first flat area 12120 and the second flat area 12220 shown in FIG. 2 are areas formed by flattening the first exposed portion 1212 and the second exposed portion 1222 shown in FIG. 1 to increase a soldering area between the first exposed portion 1212 of the first conductive pin 121 and the first soldering area P103 of the circuit substrate P, and between the second exposed portion 1222 of the second conductive pin 122 and the second soldering area P104 of the circuit substrate P. However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

It should be noted that as shown in FIG. 7, in another possible embodiment, the supporting portion 21 of the capacitor supporting structure 2 has a plurality of heat dissipation openings 21002 for partially exposing an outer surface 13100 of the package casing 131 of the package assembly 13 of the wound capacitor package structure 1. Therefore, the wound capacitor package structure 1 can not only dissipate heat through the exposed area that is not shielded by the supporting portion 21 of the capacitor carrying structure 2, but the wound capacitor package structure 1 can also dissipate heat through the heat dissipation openings 21002 of the supporting portion 21. However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

Second Embodiment

Referring to FIG. 3, FIG. 8, FIG. 9 and FIG. 10, a second embodiment of the present disclosure provides an assembly method of a laterally placed capacitor package assembly S, which includes: firstly, providing a wound capacitor package structure 1 and a capacitor supporting structure 2 on a circuit substrate P, in which the capacitor supporting structure 2 has a supporting portion 21 passing through the circuit substrate P and a plurality of positioning portions 22 disposed on the circuit substrate P (step S100); and then electrically connecting the wound capacitor package structure 1 to the circuit substrate P by soldering or any conductive method (step S102). More particularly, the wound capacitor package structure 1 includes a wound assembly 11, a conductive assembly 12 and a package assembly 13, the conductive assembly 12 includes a first conductive pin 121 electrically contacting the wound assembly 11 and a second conductive pin 122 electrically contacting the wound assembly 11, and the wound assembly 11 is disposed inside (or can be enclosed by) the package assembly 13. Moreover, the supporting portion 21 of the capacitor supporting structure 2 is configured to support or carry the wound capacitor package structure 1, and the plurality of positioning portions 22 of the capacitor supporting structure 2 are configured to extend outward from the supporting portion 21. In addition, the first exposed portion 1212 of the first conductive pin 121 and the second exposed portion 1222 of the second conductive pin 122 laterally or horizontally extend from the package assembly 13 without bending and are electrically connected to the circuit substrate P.

For example, referring to FIG. 3, FIG. 8 and FIG. 9, the step S100 of providing the wound capacitor package structure 1 and the capacitor supporting structure 2 on the circuit substrate P further includes: firstly, referring to FIG. 8 and FIG. 9, laterally or horizontally placing the wound capacitor package structure 1 on the capacitor supporting structure 2 (step S1002); and then referring to FIG. 3 and FIG. 8, placing the capacitor supporting structure 2 that is configured to support the wound capacitor package structure 1 on the circuit substrate P (step S1004). However, the aforementioned details are disclosed for exemplary purposes only, and are not meant to limit the scope of the present disclosure.

For example, referring to FIG. 3, FIG. 8 and FIG. 10, the step S100 of providing the wound capacitor package structure 1 and the capacitor supporting structure 2 on the circuit substrate P further includes: firstly, referring to FIG. 8 and FIG. 10, placing the capacitor supporting structure 2 on the circuit substrate P (step S1006); and then referring to FIG. 3 and FIG. 8, laterally or horizontally placing the wound capacitor package structure 1 on the capacitor supporting structure 2 (step S1008).
