CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is based on and claims priority under 35 U.S.C. 119 to Korean Patent Application Serial No. 10-2019-0096178, filed on Aug. 7, 2019, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.

BACKGROUND

The present disclosure relates generally to an electronic device with a shield can structure, which includes one or more fastening structures for accurately mounting a shield can on a printed circuit board.

2. Description of Related Art

As electronic devices are highly integrated, and high-speed, high-volume wireless communication becomes commonplace, an electronic device, such as a mobile communication terminal, is recently being equipped with various functions. For example, an electronic device comes with the integrated functionality, including an entertainment function, such as video games, a multimedia function, such as replaying music/videos, a communication and security function for mobile banking, and a scheduling or e-wallet function.

An electronic device may include various electronic components for running various functions. For example, electronic elements or circuit lines may be mounted on a printed circuit board (PCB), and at least some of them may be electrically connected. The electronic components may cause electromagnetic waves. Generally, electromagnetic waves may be useful in some cases (e.g., for radio communication or satellite communication purposes) but, in other cases, may negatively affect the operation of electronic devices. One example of such negative influence is electromagnetic interference (EMI). The EMI generated from each electronic component may be harmful for the human body and may cause noise to vulnerable devices. Thus, upon mounting an electronic component on a printed circuit board, the electronic component may be covered with an EMI shield can.

When coupled to a PCB, a shield can may be misaligned or displaced on the printed circuit board. The misalignment or displacement of the shield can may cause a coupling deviation in the coupling area of the printed circuit board, resulting in failure to precisely mount on the printed circuit board. The shield can may come in contact with its surrounding electronic components on the printed circuit board, causing interference with the electronic components. Thus, the electronic components may malfunction.

FIG. 5is an exploded perspective view of a configuration of a shield can structure400included in an electronic device101, according to an embodiment.FIG. 6is a plan view of one or more first, second, and/or third fastening structures430,440, and450formed on a circuit board410in a configuration of a shield can structure400included in an electronic device101, according to an embodiment.FIG. 7is a perspective view of a coupled state of a shield can structure400included in an electronic device101, according to an embodiment.FIG. 8is a plan view of a coupled state of a shield can structure400included in an electronic device101, according to an embodiment.

Referring toFIGS. 5 to 8, a shield can structure400included in an electronic device101may include a housing310, a circuit board410on which one or more electronic components411are mounted, a shield can420, and one or more first, second, and/or third fastening structures430,440, and450. The circuit board410may be disposed in the housing310of the electronic device101. The shield can420may be coupled to the circuit board410and, to shield EMI caused from the one or more electronic components411, the shield can420may cover the one or more electronic components411.

The shield can420may include at least one of a conductive material, metal, or stainless steel. The shield can420may include a non-conductive material in addition to the conductive material.

The one or more first, second, and/or third fastening structures430,440, and450may be formed on the top surface of the circuit board410. The one or more first, second, and/or third fastening structures430,440, and450may be formed of a conductive pad. The conductive pad may be a copper pad. Although a copper pad is used as an example of the one or more first, second, and/or third fastening structures430,440, and450, embodiments of the disclosure are not limited thereto. The one or more first, second, and/or third fastening structures430,440, and450may be formed of various conductive materials.

The one or more first fastening structures430may be formed in various shapes corresponding to the shape and size of the shield can420. The one or more first fastening structures430may have a first width A1along a first direction L1(e.g., the lengthwise direction), and both ends of the one or more first fastening structures430may be formed in a semi-circular shape. The one or more first fastening structures430may have a first width A1along a second direction L2(e.g., a direction perpendicular to the lengthwise direction) perpendicular to the first direction L1(e.g., the lengthwise direction). The one or more second fastening structures440may extend from the one or more first fastening structures430and may have a second width A2smaller than the first width A1. The one or more second fastening structures440may be formed between the one or more first fastening structures430.

The one or more second fastening structures440may include at least one of a curved shape or a straight line shape. The one or more second fastening structures440may be shaped as a curve. At least a portion of the shield can420may be shaped as a curve, and the curved portion of the shield can420may face the one or more second fastening structures440shaped as a curve.

The one or more third fastening structures450may be formed inside the one or more first fastening structures430and may have a third width A3smaller than the first width A1. The one or more third fastening structures450may include at least one of a curved shape or a straight line shape. The one or more third fastening structures450may be shaped as a straight line. At least a portion of the shield can420may be shaped as a straight line, and the straight portion of the one or more third fastening structures450may face at least a portion of the shield can420shaped as a straight line.

As such, the one or more second fastening structures440may be formed in a curved shape between the one or more first fastening structures430, and the one or more third fastening structures450may be shaped as a straight line inside the one or more first fastening structures430.

In this state, solder cream (e.g., C1ofFIG. 9) may be applied to the first, second, and/or third fastening structures430,440, and450using a soldering device. The shield can420may be mounted on the applied solder cream C1.

While the shield can420is coupled to the top surface of the circuit board410, the bottom surface of the shield can420may simultaneously be rendered to face the solder cream (C1)—applied first, second, and/or third fastening structures430,440, and450. For example, the shield can420may be mounted on the applied solder cream C1.

In this state, the solder cream C1may be thermally treated and, in a predetermined time, the solder cream C1may turn solid. In this case, the solid solder cream C1solders the first, second, and/or third fastening structures430,440, and450with the shield can420. When thermally treated at a high temperature, the solder cream C1may be hardened while simultaneously pulling the shield can420by surface tension. At this time, the solder cream C1may precisely position and solder the shield can420to the first, second, and/or third fastening structures430,440, and450by surface tension.

Since the second and third widths A2and A3of the second and third fastening structures440and450are smaller than the first width A1of the first fastening structure430, if the solder cream C1is thermally treated at a high temperature, large surface tension may be caused at the second and third widths A2and A3than at larger widths and, thus, the shield can420may be precisely positioned and coupled to the centers of the first, second, and/or third fastening structures430,440, and450. When the second and third widths A2and A3are equal to or larger than the first width A1, the shield can420may be soldered off the centers of the first, second, and/or third fastening structures430,440, and450. Thus, the second and third widths A2and A3which are smaller than the first width A1may prevent the shield can420from being out of place or twisted on the top surfaces of the first, second, and/or third fastening structures430,440, and450, coupling the shield can420securely and precisely in place.

FIGS. 9A, 9B, and 9Care plan views of a process of coupling a shield can structure400included in an electronic device101, according to an embodiment.

Referring toFIGS. 9A, 9B, and 9C, the shield can structure400included in the electronic device101may include a housing310of the electronic device101, a circuit board410having one or more electronic components411mounted thereon, a shield can420covering one or more electronic components411, a first fastening structure430with a first width A1, a second fastening structure440with a second width A2smaller than the first width A1, and a third fastening structure450with a third width A3smaller than the first width A1.

As shown inFIG. 9A, the one or more one or more first fastening structures430may be formed around one or more electronic components411mounted on the circuit board410. The one or more first fastening structures430may be formed on the top surface of the circuit board410. The one or more second fastening structures440may extend from the one or more first fastening structures430and be formed between the one or more first fastening structures430. The one or more second fastening structures440may be curved. The one or more curved second fastening structures440may be formed between the one or more first fastening structures430while connecting the one or more first fastening structures430.

The one or more third fastening structures450may be formed inside the one or more first fastening structures430. The one or more third fastening structures450may be shaped as a straight line.

In this state, solder cream C1may be applied to the top surfaces of the one or more first, second, and/or third fastening structures430,440, and450using a soldering device, as shown inFIG. 9B. Next, the shield can420may be mounted on the applied solder cream C1. At this time, the shield can420may be placed on top of the first, second, and/or third fastening structures430,440, and450.

Simultaneously, the bottom of the shield can420may be brought in contact with the top surface of the solder cream C1while the shield can420covers the one or more electronic components411.

If thermal treatment is performed as shown inFIG. 9C, with the circuit board410and the shield can420coupled together, the solder cream C1applied onto the top surfaces of the first, second, and/or third fastening structures430,440, and450may be melted, causing surface tension. The solder cream C1may be held together, by surface tension, on the surface of the first, second, and/or third fastening structures430,440, and450while aligning the shield can420onto the first, second, and/or third fastening structures430,440, and450. When hardened by the thermal treatment, the solder cream C1pulls the shield can420by surface tension while simultaneously allowing the shield can420to be positioned in place on, and be soldered to, the first, second, and/or third fastening structures430,440, and450.

As such, as the second and third widths A2and A3of the second and third fastening structures440and450are smaller than the first width A1of the first fastening structure430, the surface tension at the second and third widths A2and A3is larger than the surface tension at the first width A1which is larger than the second and third widths A2and A3when the solder cream C1is thermally treated, so that the shield can420may be positioned precisely in place on, and coupled to, the top surfaces of the first, second, and/or third fastening structures430,440, and450. In other words, the second and third widths A2and A3of the second and third fastening structures440and450allow the shield can420to be positioned and coupled precisely to the centers of the first, second, and/or third fastening structures430,440, and450. Further, it is possible to prevent interference with one or more adjacent electronic components411and other shield can420mounted on the circuit board410.

The first and second guide portions561and562may be formed to project from the centers of both ends of the one or more first fastening structures530along the first direction L1.

The first and second guide portions561and562may have a guide width B2smaller than the first width B1.

In this state, solder cream (e.g., C1ofFIG. 14) may be applied to the first fastening structure530and the guide portions560using a soldering device. The shield can520may be mounted on the applied solder cream C1.

At this time, the shield can520may be coupled onto the top surface of the circuit board510while the bottom surface of the shield can520may face the one or more first fastening structures530and the first and second guide portions561and562. At this time, the shield can520may be guided and coupled by the first and second guide portions561and562projecting from both ends of the one or more first fastening structures530.

Thus, thermal treatment on the one or more first fastening structures530and the one or more guide portions560may be easily appreciated from the above-described embodiments and, thus, no detailed description thereof is given.

FIGS. 14A, 14B, and 14Care plan views of a process of coupling a shield can structure500included in an electronic device101, according to an embodiment.

Referring toFIGS. 14A, 14B, and 14C, a shield can structure500included in an electronic device101may include a housing310of the electronic device101, a circuit board510on which one or more electronic components (e.g., the electronic component411ofFIG. 14) are mounted, a shield can520covering the one or more electronic components411, one or more first fastening structures530, and one or more guide portions560. The one or more guide portions560may include a first guide portion561and a second guide portion562. The first guide portion561may be formed to project from the center of an end of the one or more first fastening structures530. The second guide portion562may be formed to project from the center of the other end of the one or more first fastening structures530.

As shown inFIG. 14A, the one or more first fastening structures530may be formed around one or more electronic components411mounted on the circuit board510. The one or more first fastening structures530may be formed on the top surface of the circuit board510. At this time, the first and second guide portions561and562formed to project from the centers of both ends of the first fastening structure530may be formed on the top surface of the circuit board510as are the one or more first fastening structures530. At this time, the shield can520may be guided by the first and second guide portions561and562to be coupled to the centers of the one or more first fastening structures530. Thus, the shield can520may be mounted, precisely positioned along the centers of the one or more first fastening structures530by the first and second guide portions561and562.

In this state, solder cream C1may be applied to the top surfaces of the one or more first fastening structures530and the one or more guide portions560using a soldering device, as shown inFIG. 14B. At this time, the solder cream C1may also be applied to the first and second guide portions561and562included in the one or more guide portions560.

Next, the shield can520may be mounted on the applied solder cream C1. At this time, the shield can520may be placed precisely on the centers of the one or more first fastening structures530by the one or more guide portions560. The one or more guide portions560may guide the shield can520to be positioned precisely on the centers of the one or more first fastening structures530. At this time, when the shield can520is mounted precisely on the centers of the one or more first fastening structures530, the bottom of the shield can520may be brought in contact with the top surface of the solder cream C1while the shield can520may simultaneously cover the one or more electronic components411.

If thermal treatment is performed as shown inFIG. 14C, with the circuit board510and the shield can520coupled together, the solder cream C1applied onto the top surfaces of the one or more first fastening structures530and the one or more guide portions560may be melted, causing surface tension. The solder cream C1may be held together, by surface tension, on the surface of the first fastening structure530while aligning the shield can520onto the first fastening structure530. When hardened by the thermal treatment, the solder cream C1pulls the shield can520by surface tension while simultaneously allowing the shield can520to be positioned in place on, and be soldered to, the first fastening structure530.

As such, as the guide width B2of the first and second guide portions561and562is smaller than the first width B1of the first fastening structure530, the surface tension at the guide width B2is larger than the surface tension at the first width B1which is larger than the guide width B2when the solder cream C1is thermally treated, so that the shield can520may be positioned precisely in place on, and coupled to, the top surface of the first fastening structure530. Thus, the first and second guide portions561and562may allow soldering to be performed, with the shield can520precisely positioned to the center of the first fastening structure530. Thus, it is possible to prevent interference with one or more adjacent electronic components411and other shield can520mounted on the circuit board510.

The one or more first fastening structures630may be formed along a first direction L1(e.g., the lengthwise direction of the one or more first fastening structures630), and both ends of the one or more first fastening structures630may be formed in a semi-circular shape. The one or more first fastening structures630may have a first width D1in a second direction L2(e.g., a direction perpendicular to the lengthwise direction of the one or more first fastening structures630) which is perpendicular to the first direction L1(e.g., the lengthwise direction of the one or more first fastening structures630).

The shield can620may have the one or more coupling portions670that couple to the one or more first fastening structures630. The one or more coupling portions670may include a first coupling portion671and a second coupling portion672.

The first and second coupling portions671and672may be arranged in opposite directions on the side bottom of the shield can620. The first and second coupling portions671and672may be formed alternately in the external and internal directions on the side bottom of the shield can620. The first and second coupling portions671and672may be formed in an L shape. The first and second coupling portions671and672may be formed in a shape other than the L shape.

In this state, solder cream C1may be applied to the first fastening structure630using a soldering device. The shield can620may be mounted on the applied solder cream C1.

At this time, the shield can620may be coupled onto the top surface of the circuit board610while the first and second coupling portions671and672formed on the bottom of the shield can620may face the top surface of the one or more first fastening structures630and be placed on the solder cream C1.

A thermal treatment process on the one or more first fastening structures630and the first and second coupling portions671and672may be at least partially identical or similar in configuration to the thermal treatment process on the one or more first fastening structures430described above. Thus, thermal treatment on the one or more first fastening structures630and the first and second coupling portions671and672may be easily appreciated from the above-described embodiments and, thus, no detailed description thereof is given.

FIGS. 20A, 20B, and 20Care plan views of a process of coupling a shield can structure600included in an electronic device101, according to an embodiment.

Referring toFIGS. 20A, 20B, and 20C, a shield can structure600included in an electronic device101may include a housing310of the electronic device, a circuit board610on which one or more electronic components411are mounted, a shield can620covering the one or more electronic components411, one or more first fastening structures630, and one or more coupling portions670. The one or more coupling portions670may include a first coupling portion671and a second coupling portion672.

As shown inFIG. 20A, the one or more one or more first fastening structures630may be formed around one or more electronic components411mounted on the circuit board610. The one or more first fastening structures630may be formed on the top surface of the circuit board610.

In this state, solder cream C1may be applied to the top surfaces of the one or more first fastening structures630using a soldering device, as shown inFIG. 20B.

Next, the shield can620may be mounted on the applied solder cream C1. At this time, the first coupling portion671of the shield can620may be coupled to at least some surface of the one or more first fastening structures630, and the second coupling portion672of the shield can620may be coupled to at least some surface of the one or more first fastening structures630. For example, when the shield can620is mounted on the solder cream C1, the first coupling portion671of the shield can620may be coupled to the solder cream C1applied to at least some surface of the one or more first fastening structures630, and the second coupling portion672of the shield can620may be coupled to the solder cream C1applied to at least some surface of the one or more first fastening structures630. Simultaneously, the shield can620may cover the one or more electronic components411.

If thermal treatment is performed as shown inFIG. 20C, with the circuit board610and the shield can620coupled together, the solder cream C1applied onto at least some surface of the one or more first fastening structures630may be melted, causing surface tension. The solder cream C1may be held together, by surface tension, on the surface of the first fastening structure630while aligning the first and second coupling portions671and672of the shield can620onto the first fastening structure630. When hardened by the thermal treatment, the solder cream C1pulls the shield can620by surface tension while simultaneously allowing the first and second coupling portions671and672of the shield can620to be positioned in place on, and be soldered to, the first fastening structure630.

As such, the first and second coupling portions671and672of the shield can620may be bent externally or internally on the side bottom of the shield can620and be coupled to at least some surface of the top of the one or more first fastening structures630to which the solder cream C1has been applied. Thus, when the solder cream C1is thermally treated, the first and second coupling portions671and672may be soldered and coupled to at least some surface of the top of the one or more first fastening structures630by the surface tension of the solder cream C1. Thus, the first and second coupling portions671and672of the shield can620may add a coupling force on the top surface of the first fastening structure630and prevent the shield can620from being misaligned or displaced from the one or more first fastening structures630. Thus, it is possible to prevent interference with one or more adjacent electronic components411and other shield can620mounted on the circuit board610.

According to an embodiment, an electronic device including a shield can structure includes a housing, a circuit board disposed in the housing and having one or more electronic components mounted thereon, a shield can coupled to the circuit board and covering the one or more electronic components, one or more first fastening structures formed on the circuit board and coupled to the shield can, the one or more first fastening structures having a first width, and one or more second fastening structures extending from the one or more first fastening structures, the one or more second fastening structures having a second width smaller than the first width.

The one or more second fastening structures may include at least one of a curved shape or a straight line shape.

The one or more first fastening structures may further include one or more guide portions guiding the coupling of the shield can.

The one or more guide portions may include a first guide portion and a second guide portion. The first guide portion may project from a center of an end of the one or more first fastening structures, and the second guide portion may project from a center of another end of the one or more first fastening structures.

The first and second guide portions may have a guide width smaller than the first width.

The one or more first and second fastening structures may be formed of conductive pads which may be copper pads.

The one or more first fastening structures may include one or more third fastening structures individually formed inside the one or more first fastening structures and having a third width smaller than the first width.

According to an embodiment, an electronic device including a shield can structure includes a housing, a circuit board disposed in the housing, one or more electronic components mounted on the circuit board, a shield can coupled to the circuit board and covering the one or more electronic components, and one or more first fastening structures formed on the circuit board and coupled to the shield can, the one or more first fastening structures having a first width. The shield can includes one or more coupling portions coupled to the one or more first fastening structures.

The one or more coupling portions may include a first coupling portion and a second coupling portion. The first coupling portion may be externally bent from a side bottom of the shield can, and the second coupling portion may be internally bent from the side bottom of the shield can.

The first and second coupling portions may be arranged in opposite directions on the side bottom of the shield can.

According to an embodiment, a shield can structure includes a circuit board having one or more electronic components mounted thereon, a shield can coupled to the circuit board and covering the one or more electronic components, one or more first fastening structures formed on the circuit board and coupled to the shield can, the one or more first fastening structures having a first width, and one or more second fastening structures extending from the one or more first fastening structures, the one or more second fastening structures having a second width smaller than the first width.

According to an embodiment, a shield can structure includes a circuit board having one or more electronic components mounted on thereon, a shield can coupled to the circuit board and covering the one or more electronic components, and one or more first fastening structures formed on the circuit board and coupled to the shield can, the one or more first fastening structures having a first width. The shield can includes one or more coupling portions coupled to the one or more first fastening structures.

As is apparent from the foregoing description, one or more first, second, and/or third fastening structures with a first, second, and/or third width are formed. The second and third widths of the second and third fastening structures are smaller than the first width of the first fastening structure, so that upon thermal treatment using solder cream, larger surface tension is caused at the second and third widths than at the first width larger than the second and third widths. Thus, the shield can may be mounted without misalignment or displacement on the top surface of the first, second, and/or third fastening structure. Thus, the shield can may be precisely positioned and soldered to the center of the first, second, and/or third fastening structure. Thus, the shield can may be securely and precisely mounted on the top surface of the first, second, and/or third fastening structure. It is also possible to reduce coupling deviation from one or more adjacent electronic components and other shield cans and to prevent interference between electronic components.

Further, one or more guide portions are formed to precisely position the shield can on the one or more first fastening structures formed on the circuit board. The one or more guide portions allow the shield can to be precisely mounted on the first fastening structures.

The shield can has one or more coupling portions bent externally or internally from the side bottom of the shield can. The shield can may be coupled to the one or more first fastening structures formed on the circuit board using the one or more coupling portions. Thus, the circuit board and the shield can may be coupled more securely or firmly. It is also possible to prevent the shield can from being misaligned or displaced from the one or more first fastening structures.
