Description

Technical Field

[0001] Various embodiments of this disclosure relate to printed circuit boards including ground lines. Background Technology

[0002] To meet the increasing demand for wireless data traffic since the deployment of 4G communication systems, efforts have been made to develop improved 5G or pre-5G communication systems. Therefore, 5G or pre-5G communication systems are also referred to as "beyond 4G network" communication systems or "post-LTE" systems.

[0003] 5G communication systems are considered to be implemented in millimeter-wave bands (e.g., 60 GHz band) to achieve higher data rates. To reduce radio wave propagation loss and increase transmission distance in the UHF band, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive MIMO technologies are discussed in 5G communication systems.

[0004] In addition, in 5G communication systems, development for system network improvements is underway based on advanced small cells, cloud radio access networks (cloud RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, moving networks, cooperative communication, cooperative multipoint (CoMP), and receiver interference cancellation.

[0005] In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) as advanced coding and modulation (ACM), as well as filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies, have also been developed. Summary of the Invention

[0006] Technical issues

[0007] To provide compact products, printed circuit boards (such as printed circuit boards (PCBs) and flexible PCBs (FPCBs)) can be used to connect antennas and communication modules (such as 5G, WiFi, etc.) or for high-speed interfaces. Regarding PCBs for electronic devices, grounding in areas adjacent to via pads can be removed to prevent signal congestion. However, when electronic devices are used in the UHF band, impedance mismatch can occur in open areas where no grounding is formed, leading to RF losses.

[0008] Various embodiments of this disclosure may provide a printed circuit board that can reduce impedance mismatch that can occur in an opening region formed on a ground having via pads located thereon.

[0009] The problems to be solved by the embodiments of this disclosure are not limited to those described above, and can be extended in various ways without departing from the spirit and scope of this disclosure.

[0082] Figure 6 This is a perspective view of a printed circuit board according to various embodiments of the present disclosure.

[0083] according to Figure 6 The printed circuit board 400 may include a ground line 404, a ground 406, a pass pad 408, and a pass 450. Figure 6 The configuration of the printed circuit board 400 in the middle can be with Figure 5 The configuration of the circuit board 400 is completely or partially the same.

[0084] According to various embodiments, ground 406 can be directed to electronic devices (e.g., Figure 1 Electronic components (e.g., electronic devices 101) Figure 5 The first antenna 334 in the circuit provides a reference potential. For example, ground 406 can be capacitively coupled to the via pad 408 of the printed circuit board 400. For example, ground 406 can include the first ground described below (e.g., Figure 7 The first ground 416) and the second ground (e.g. Figure 7 The second grounding (426) in the middle.

[0085] According to various embodiments, the passage 450 can electrically connect wire lines (e.g., on different layers of the printed circuit board 400) to wire lines (e.g.) Figure 7 (First line 434b and second line 444b in the example). For example, the interior of the passage 450 may be filled with electrical conductors, and the lines may be electrically connected through the electrical conductors within the passage 450 and the passage pads 408.

[0086] According to various embodiments, the via pad 408 may be formed in a shape that surrounds at least a portion of the via 450. For example, the via pad may be formed in a shape substantially similar to the shape of the via 450 (e.g., a circle) to surround the via 450, and may be formed in various shapes other than those shown (e.g., ellipse, polygon, etc.).

[0087] According to various embodiments, the pass pad 408 may surround at least a portion of the pass 450. According to one embodiment, the pass 450 may extend through the pass pad 408. For example, the pass pad 408 may surround at least a portion of a side surface (e.g., an XY plane) of the pass 450. According to another embodiment, the pass 450 may be disposed between a plurality of pass pads 408. For example, the pass 450 may be disposed between a first pass pad 434a and a second pass pad 444a.

[0088] According to various embodiments, the printed circuit board 400 may include a first substrate 400a and a second substrate 400b connected to the first substrate 400a. At least one of the first substrate 400a and the second substrate 400b may be formed of a flexible printed circuit board. According to one embodiment, the second substrate 400b may include more layers than the first substrate 400a. For example, the second substrate 400b may include four conductive layers, while the first substrate 400a may include two conductive layers. As the number of layers of the first substrate 400a and the second substrate 400b changes, the impedance of the printed circuit board 400 may vary in the region where the pass pads 408 and the passes 450 (pass pads 408 and passes 450 connecting to wires of the first substrate 400a and the second substrate 400b) are disposed.

[0089] According to various embodiments, the printed circuit board 400 may include an opening 402 formed in ground 406 at a location corresponding to the via pad 408. For example, when the printed circuit board 400 is viewed in a second direction (-Z direction), at least a portion of the opening 402 may be formed to overlap with the via pad 408. Therefore, crosstalk of signals passing around the ground 406 in which the opening 402 is formed can be reduced. For example, the opening 402 can reduce the area in which the via pad 408 and the ground 406 directly face each other, thereby reducing interference between the via pad 408 and the ground 406.

[0090] According to various embodiments, the printed circuit board 400 may include a ground line 404 located in the opening 402. For example, the ground line 404 may be disposed on the printed circuit board 400 and cross the opening 402. In one embodiment, the ground line 404 may form a capacitive coupling with at least one of the inner layers of the printed circuit board 400. For example, the ground line 404 may form a capacitive coupling with a pass pad 408. Through the capacitance formed between the ground line 404 and the pass pad 408, the printed circuit board 400 may be configured to have a characteristic impedance Z0 having a preset value (e.g., about 50 Ω).

[0091] According to various embodiments, the fifth width w5, which is the width of the second line 444b, can be greater than the first width w1, which is the width of the ground line 404. For example, relative to the first width w1 and / or the second width (e.g., Figure 8 The second width w2 and the fifth width w5 can be formed to achieve a specified ratio (e.g., four to five times). For example, the first width w1 can be formed to be approximately 45 μm and the fifth width w5 can be formed to be approximately 200 μm.

[0092] According to various embodiments, the characteristic impedance can be formed based on the capacitance C. According to one embodiment, the characteristic impedance Z0 can be expressed as Equation 1, as shown below. In Equation 1, R can represent resistance, L can represent inductance, G can represent conductance, and C can represent capacitance.

[0093] Equation 1

[0094]

[0095] According to various embodiments, capacitor C can be formed based on the area of ​​the overlap between the via pad 408 and the ground line 404 (e.g., area A in Equation 2 as shown below) and the distance between the via pad 408 and the ground line 404 (e.g., distance d in Equation 2). The area A of the overlap between the via pad 408 and the ground line 404 can be based on a first width w1 and a fourth width (e.g., the width of the ground line 404) of the ground line 404. Figure 8 The fourth width w4 is formed, and the distance d between the pass pad 408 and the ground line 404 can be based on the first thickness (e.g., the fourth width w4). Figure 8 The first thickness t1) or the third thickness (e.g.) Figure 8 At least one of the third thickness t3) is formed. According to one embodiment, capacitor C can be expressed as Equation 2 as shown below. In Equation 2, ε0 can represent the material located between the pass pad 408 and the ground line 404 (e.g., Figure 8 The dielectric constant of the insulating layer (470) in the middle.

[0096] Equation 2

[0097]

[0098] According to various embodiments, when ground line 404 is viewed in a first direction (+Z direction) or a second direction (-Z), ground line 404 may at least partially overlap the via pad 408 and / or the trace (e.g., Figure 7 (The first line route 434b and the second line route 444b in the diagram). In addition, the ground line 404 is not limited to the example shown and can be formed in various shapes.

[0099] According to one embodiment, the passage 450 can be disposed at various locations on the printed circuit board 400. According to one embodiment, the passage 450 can be disposed at a location on the printed circuit board 400 adjacent to the connecting member 480. For example, the passage 450 can be electrically connected to at least one of the first connecting member 482 and the second connecting member 484. Multiple passages 450 can be provided and can include a first passage 450a connected to the first connecting member 482 and a second passage 450b connected to the second connecting member 484. According to another embodiment, the passage 450 can be disposed on the second substrate 400b adjacent to the first substrate 400a. For example, the passage 450 can include first passage pads (e.g., those electrically connected to the first substrate 400a and the second substrate 400b respectively). Figure 7 The first channel pad 434a) and the second channel pad (e.g. Figure 7 The second path pad 444a is shown in the figure. The ground line 404 may be configured to correspond to the path pad 408 and the path 450 to transform the impedance of the path pad 408 and the path 450 to a preset impedance. According to various embodiments, the path pad 408 may be located in at least a portion of the opening 402.

[0100] According to various embodiments, the printed circuit board 400 may include a ground path 460. The ground path 460 may be connected to a ground 406, thereby stably maintaining the potential of the printed circuit board 400. For example, the ground path 460 may be formed to extend through at least a portion of the ground 406.

For example, the printed circuit board 400 may include a first layer 410 oriented in a first direction (+Z direction), a second layer 420 oriented in a second direction (-Z direction) opposite to the first direction (+Z direction), and a plurality of conductive layers disposed between the first layer 410 and the second layer 420. For example, the printed circuit board 400 may also include a third layer 430 disposed between the first layer 410 and the second layer 420, and a fourth layer 440 disposed between the third layer 430 and the second layer 420.

[0103] According to one embodiment, the first layer 410 and / or the second layer 420 may be formed to be thicker than the third layer 430 and / or the fourth layer 440. For example, the first layer 410 and / or the second layer 420 may be formed to have a thickness of approximately 20 μm, and the third layer 430 and / or the fourth layer 440 may be formed to have a thickness of approximately 6 μm.

[0104] In this disclosure, for ease of illustration, although a printed circuit board formed of four layers is described, the printed circuit board including ground lines described in this disclosure can also be applied to printed circuit boards with four or more layers, such as printed circuit boards formed of six or eight layers. Figure 7 and Figure 8 The configuration of the printed circuit board 400 in the middle can be with Figure 5 and Figure 6 The configuration of the printed circuit board 400 in the middle is completely or partially the same.

[0105] According to various embodiments, the thickness of the conductive layer 401 can be formed differently. For example, the thickness of the first layer 410 and the second layer 420 exposed to the outside of the printed circuit board 400 can be thicker than the thickness of the inner layers of the printed circuit board 400 (e.g., the third layer 430 or the fourth layer 440).

[0106] According to various embodiments, the first layer 410 may include a first ground 416, and the second layer 420 may include a second ground 426.

According to one embodiment, the first ground 416 may be capacitively coupled to a third layer 430 disposed below the first layer 410 (e.g., in the -Z direction), and the second ground 426 may be capacitively coupled to a fourth layer 440. Therefore, crosstalk of signals in the printed circuit board 400 can be reduced by the first ground 416 and the second ground 426.

According to one embodiment, the first ground 416 in which the first opening 412 is formed can reduce signal crosstalk. For example, the first opening 412 may be formed in the first ground 416 corresponding to the via pad 408, thus reducing the area where the first ground 416 with the first opening 412 and the first via pad 434a face each other. Therefore, interference to signals passing through the via pad 408 can be reduced.
