Abstract
Description
Printed circuit board and electronic device including same
[0001] The present disclosure relates to a printed circuit board and an electronic device including the same.
[0002] When mounting DIP (dual in-line package) type electronic components on a printed circuit board, through holes are formed on the mounting surface of the printed circuit board, and the lead wires of the electronic components are inserted into the through holes and then soldered. Recently, as switching mode power supplies (SMPS) have become slimmer, the demand for leadless printed circuit boards without lead wires is increasing. Accordingly, DIP type electronic components mounted on printed circuit boards are being changed to SMD (surface mount device) type electronic components to configure SMPSs without lead wires. Among the components that can be changed to SMD type electronic components, electrolytic capacitors (EL capacitors) can be replaced with tantalum capacitors, but since they are not used for general industrial purposes, their high price causes the overall price of SMPS to increase, which is a problem.

[0055] FIG. 2 is an exploded view illustrating an electronic device according to various embodiments of the present disclosure.
[0056] An electronic device (1) according to various embodiments of the present disclosure may be a display device as illustrated in FIG. 2. The electronic device (1) may include a housing (10) forming an exterior, a display (30), and a printed circuit board (100).

For example, the mounting layer may be formed of copper. The processor (80), electrode wires or electrode pads of the plurality of electronic components and / or electronic component modules (200, 300) may be electrically connected to the mounting layer. A solder mask for corrosion prevention and a silk screen for displaying characters or symbols may be provided on the mounting layer.
[0064] FIG. 3 is a perspective view illustrating a portion of a printed circuit board of an electronic device according to various embodiments of the present disclosure. FIG. 4 is a diagram illustrating an example in which a pair of electronic component modules are arranged in an intersecting direction according to various embodiments of the present disclosure.
[0065] Referring to FIG. 3, the printed circuit board (100) may be provided with a mounting hole (110) into which a first electronic component module (210) and a second electronic component module (220) may be mounted. The mounting hole (110) may have a length along the X-axis direction of FIG. 3 and a width along the Y-axis direction of FIG. 3.
[0066] For example, the length of the mounting hole (110) may be approximately smaller than the lengths of the first electronic component module (210) and the second electronic component module (220). In this case, a plurality of first electronic components (213) mounted on the first electronic component module (210) and a plurality of second electronic components (223) mounted on the second electronic component module (220) may be inserted, and both ends of the first substrate (211) of the first electronic component module (210) and both ends of the second substrate (221) of the second electronic component module (220) may be respectively placed around the mounting hole (110). The width of the mounting hole (110) may be larger than the widths of the first electronic component module (210) and the second electronic component module (210) when the first electronic component module (210) and the second electronic component module (220) are arranged to intersect or be interleaved with each other. In this case, a part of the first substrate (211) of the first electronic component module (210) and a part of the second substrate (221) of the second electronic component module (220) can be inserted into the mounting hole (110).
[0067] The first electronic element module (210) and the second electronic element module (220) mounted on the printed circuit board (100) may be arranged to intersect each other. This may be, for example, where a plurality of second electronic elements (223) of the second electronic element module (220) are arranged one by one between a plurality of first electronic elements (213) of the first electronic element module (210). In this case, the plurality of first electronic elements (213) of the first electronic element module (210) and the plurality of second electronic elements (223) of the second electronic element module (220) inserted into the mounting hole (110) may be arranged approximately parallel to the printed circuit board (100).
[0068] Referring to FIG. 4, one second electronic element (223-1) can be inserted into a first space (S1) between a pair of adjacent first electronic elements (213-1, 213-2). In addition, one first electronic element (213-2) can be inserted into a second space (S2) between a pair of adjacent second electronic elements (223-1, 223-2). Accordingly, when the first electronic element module (210) and the second electronic element module (220) are mounted in the mounting hole (110) of the printed circuit board (100) so as to intersect each other, the first plurality of first electronic elements (213) and the second plurality of second electronic elements (223) can be arranged alternately one by one along the X-axis direction as shown in FIG. 3.
[0069] In this case, the first gap (D1) of the pair of first electronic elements (213-1, 213-2) may be greater than the first width (W1) of the first electronic element (213-1). In addition, the second gap (D2) of the pair of second electronic elements (223-1, 223-2) may be greater than the second width (W2) of the second electronic element (223-1). For example, the first gap (D1) may be approximately 1.1 to 1.2 times the first width (W1). The second gap (D2) may be approximately 1.1 to 1.2 times the second width (W2). Therefore, when a plurality of second electronic elements (223) are inserted between a plurality of first electronic elements (213), the plurality of first electronic elements (213) and the plurality of second electronic elements (223) may not interfere with each other.
[0070] FIG. 5 is an enlarged perspective view of a plurality of electronic component modules mounted on a printed circuit board of an electronic device according to various embodiments of the present disclosure.
[0071] Referring to FIG. 5, the first electronic component module (210) may be soldered to the printed circuit board (100) on one side and the other side by solder (270). Accordingly, the first electronic component module (210) and the second electronic component module (220) may be physically fixed to the printed circuit board (100). In this case, the first substrate (211) of the first electronic component module (210) and the second substrate (221) of the second electronic component module (220) may be mounted approximately vertically with respect to the mounting surface (100a) of the printed circuit board (100). Accordingly, the first electronic component module (210) and the second electronic component module (220) may be mounted on the printed circuit board (100) so as to have a minimum / relatively small height from the mounting surface (100a) of the printed circuit board (100).
[0072] The first electronic element module (210) and the second electronic element module (220) can be mutually attached by an adhesive (400). In this case, the adhesive (400) can be applied between at least one of the plurality of first electronic elements (213) and the second substrate (221), and between at least one of the second electronic elements (223) and the first substrate (211).
[0073] For example, as shown in FIG. 5, an adhesive (400) may be applied between two first electronic elements (213-1, 213-n) located at the outermost side among the plurality of first electronic elements of the first electronic element module (210) and the second substrate (221) of the electronic element module (220). In addition, an adhesive (400) may be applied between two second electronic elements (223-1, 223-n) located at the outermost side among the plurality of second electronic elements of the second electronic element module (220) and the first substrate (211) of the first electronic element module (210). Accordingly, the first electronic element module (210) and the second electronic element module (220) may be firmly fixed to each other through the adhesive (400).
[0074] Hereinafter, the first electronic component module (210) will be described with reference to the drawings. The second electronic component module (220) has substantially the same structure as the first electronic component module (210), so a detailed description thereof will be omitted.
[0075] FIG. 6 is a perspective view illustrating an electronic component module mounted on a printed circuit board of an electronic device according to various embodiments of the present disclosure. FIG. 7 is a diagram illustrating an example in which an electronic component module according to various embodiments of the present disclosure includes a DIP (dual in-line package) type capacitor.
[0076] Referring to FIG. 6, the first electronic element module (210) may include a first substrate (211) and a plurality of first electronic elements (213) arranged in one column (or one row) with a first interval (D1) on a first surface (211a) of the first substrate (211).
[0077] A first substrate (211) may be provided with a plurality of conductive metal terminals (212) on both sides of a first surface (211a) and on both sides of a second surface (211b) opposite to the first surface (211a). The plurality of conductive metal terminals (212) may be electrically and physically connected to a mounting surface (110a, see FIG. 3a) of a printed circuit board by applying solder (270). One of the conductive metal terminals (212) may be electrically connected to a first wiring (216) formed on a second surface (211b) of the first substrate (211). Another of the conductive metal terminals (212) may be electrically connected to a second wiring (218) formed on a second surface (211b) of the first substrate (211).
[0078] Referring to Fig. 7, the first electronic element (213) may be a capacitor. For example, the first electronic element (213) may be a DIP type capacitor having a first lead wire (214) and a second lead wire (215) provided at the bottom. The first lead wire (214) and the second lead wire (215) may be inserted into a first through hole (217) and a second through hole (219) provided in a first substrate (211).
[0079] The first lead wire (214) can be electrically connected to the first wiring (216) by solder (250, see FIG. 4). The second lead wire (215) can be electrically connected to the second wiring (218) by solder (250). The first wiring (216) and the second wiring (218) can be formed on the second surface (211b) of the first substrate (211) along the longitudinal direction of the first substrate (211) at a constant interval.
[0080] The first electronic element (213) is not limited to a DIP type capacitor and may be an SMD type capacitor.
[0081] FIG. 8 is a drawing showing an example of an electronic component module including a SMD (surface mount device) type capacitor according to various embodiments of the present disclosure.
[0082] As shown in Fig. 8, all of the plurality of first electronic elements (213') included in the first electronic element module (210') may be SMD type capacitors. In this case, the plurality of through holes may be omitted in the first substrate (211').
[0083] The first electronic element (213') may have a small substrate (212') provided at the bottom, and a first terminal (214') and a second terminal (215') may be provided on the lower surface of the small substrate (211'). The first substrate (211') may have a first wiring (216') and a second wiring (218') formed along the length direction of the first substrate (211') at intervals on the first surface (211a').
[0084] The first terminal (214') of the first electronic element (213') can be soldered to a first pad (216a') formed extending from the first wiring (216'). The second terminal (215') of the first electronic element (213') can be soldered to a second pad (218a') formed extending from the second wiring (218').
[0085] FIG. 9 is a drawing showing a comparative example in which a plurality of electronic component modules are individually arranged in parallel. FIG. 10 is a drawing showing an example in which a plurality of electronic component modules are arranged in pairs in an intersecting direction according to various embodiments of the present disclosure.
[0086] Referring to FIG. 9, the printed circuit board (100-1) according to the comparative example has six electronic component modules (230-1, 230-2, 230-3, 230-4, 230-5, 230-6) mounted in six mounting holes (110-1, 110-2, 110-3, 110-4, 110-5, 110-6), respectively. In this way, the printed circuit board (100-1) according to the comparative example is arranged so that the electronic component modules correspond one-to-one to the mounting holes.
[0087] In this way, when one electronic component module (230-1) is mounted in one mounting hole (110-1), a dead space (DS) occurs in the mounting hole (110-1). Due to the dead space (DS) occurring in the six mounting holes (110-1, 110-2, 110-3, 110-4, 110-5, 110-6), it is difficult to reduce the size of the printed circuit board (100-1). The dead space (DS) is caused by the gap (D3) between adjacent electronic components (233) mounted on the substrate (231) of the electronic component module (230-1).
[0088] A plurality of electronic components (233) are grasped by fingers provided on a robot arm and automatically mounted on a substrate (231). When the fingers grasp the electronic components and mount them on the substrate (231), a certain distance (D3) must be maintained between adjacent electronic components (233) to prevent or avoid interference between the fingers and electronic components previously mounted on the substrate (231). Therefore, it is difficult to reduce the distance (D3) between the plurality of electronic components (233) of the electronic component module (230-1).
[0089] The printed circuit board of the present disclosure can utilize dead space (DS) by arranging multiple electronic component modules differently from the comparative example.
[0090] Referring to FIG. 10, a printed circuit board (100-2) according to one or more embodiments of the present disclosure may have a plurality of mounting holes spaced approximately parallel to each other. The plurality of mounting holes may be first, second, and third mounting holes (110a-1, 110a-2, 110a-3).
[0091] In this case, the printed circuit board (100-1) may be mounted so that the first electronic component module (210-1) and the second electronic component module (220-1) intersect with each other in the first, second, and third mounting holes (110a-1, 110a-2, 110a-3), the third electronic component module (210-2) and the fourth electronic component module (220-2) intersect with each other, and the fifth electronic component module (210-3) and the sixth electronic component module (220-3) intersect with each other.
[0092] In this way, the printed circuit board (100-2) according to various embodiments of the present disclosure has three fewer mounting holes than the printed circuit board (100-1) of the comparative example, but can mount six electronic component modules, the same as the printed circuit board (100-1) of the comparative example.
[0093] Accordingly, the printed circuit board (100-2) according to a plurality of embodiments of the present disclosure can reduce the area where the electronic component module is mounted by approximately 40 to 50% compared to the comparative example of FIG. 9. The printed circuit board (100-2) can be reduced in size by the amount of the spare area (103). In addition, the spare area (103) of the printed circuit board (100-2) can be used as an area for mounting electronic components, etc., for implementing various additional functions of the electronic device (1).
[0094] The printed circuit board (100-2) may omit the first part (105) of the printed circuit board (100-2) positioned between the first and second mounting holes (110a-1, 110a-2) and the second part (106) of the printed circuit board (100-2) positioned between the second and third mounting holes (110a-2, 110a-3). In this case, the printed circuit board (100-2) may have six electronic component modules (210-1, 210-2, 210-3, 220-1, 220-2, 220-3) installed in one mounting hole.
[0095] The third electronic element module (210-2) and the fourth electronic element module (220-2), which are cross-aligned with each other, can be arranged adjacent to the first electronic element module (210-1), and the fifth electronic element module (210-3) and the fourth electronic element module (220-3), which are cross-aligned with each other, can be arranged adjacent to the third electronic element module (210-2). In this case, the size of the printed circuit board (100-2) can be further reduced by the size of the first portion (105) and the second portion (106).
[0096] FIG. 11 is a drawing showing an example of arranging a plurality of electronic component modules in horizontal and vertical directions according to various embodiments of the present disclosure.
[0097] Referring to FIG. 11, a printed circuit board (100-3) according to various embodiments of the present disclosure can arrange a plurality of electronic component modules in various directions depending on its shape.
[0098] For example, the printed circuit board (100-3) may have a shape in which the upper right side of the printed circuit board (100-3) is cut off. The printed circuit board (100-3) may have a width wider than the upper width of the printed circuit board (100-3), and the first electronic component module (210b-1) and the second electronic component module (220b-1) may be arranged to cross each other along the first direction (e.g., the X-axis direction of FIG. 11) on the lower side of the printed circuit board (100-3). The printed circuit board (100-3) may be arranged so that the third electronic component module (210b-2) and the fourth electronic component module (220b-2) are intersected with each other along the second direction (e.g., the Y-axis direction of FIG. 11) on the upper left side of the printed circuit board (100-3), and the fifth electronic component module (210b-3) and the sixth electronic component module (220b-3) are intersected with each other along the second direction.
[0099] The lengths of the third electronic component module (210b-2), the fourth electronic component module (220b-2), the fifth electronic component module (210b-3), and the sixth electronic component module (220b-3) may be shorter than the lengths of the first electronic component module (210b-1) and the second electronic component module (220b-1), respectively. Accordingly, the length of the first mounting hole (110b-1) may be formed to be longer than the lengths of the second and third mounting holes (110b-2, 110b-3).
[0100] In this way, the printed circuit board (100-3) can apply various arrangement directions and lengths of multiple electronic element modules in consideration of its shape, thereby improving ease of manufacturing.
[0101] A pair of electronic component modules (210, 220) arranged to cross each other as shown in Fig. 5 can be firmly fixed to each other using an adhesive (400). Hereinafter, a printed circuit device in which a pair of electronic component modules can be firmly fixed to each other without using an adhesive (400) will be described with reference to the drawings.
[0102] FIG. 12 is a diagram showing an example in which a pair of electronic component modules are arranged in an intersecting direction according to various embodiments of the present disclosure. FIG. 13 is a diagram showing a substrate of an electronic component module according to various embodiments of the present disclosure illustrated in FIG. 12.
[0103] Referring to FIG. 12, a plurality of first electronic elements (213c) of a first electronic element module (210c) can be mounted in the mounting holes (110c) of a printed circuit board (100-4) so as to intersect each other. In this case, the tip ends (214c) of the plurality of first electronic elements (213c) of the first electronic element module (210c) can each penetrate the second substrate (221c) of the second electronic element module (220c). The tip ends (224c) of the plurality of second electronic elements (223c) of the second electronic element module (220c) can each penetrate the first substrate (211c) of the first electronic element module (210c).
[0104] Referring to FIG. 13, a first substrate (211c) of a first electronic component module (210c) may have first wiring (216c) and second wiring (218c) spaced apart from each other along the length direction of the first substrate (211c) on a second surface (290c). The first surface of the first substrate (211c) is formed on an opposite side of the second surface (290c), and a plurality of first electronic components (213c) may be mounted thereon. The first wiring (216c) may be connected to a plurality of first through-holes (217c), and the second wiring (218c) may be connected to a plurality of second through-holes (219c). The first wiring (216c) can be electrically connected to one of the conductive metal terminals (212c), and the second wiring (218c) can be electrically connected to another of the conductive metal terminals (212c).
[0105] A first substrate (211c) of a first electronic element module (210c) may be provided with a plurality of first insertion holes (260c) into which the tip portions (224c) of a plurality of second electronic elements (223c) of a second electronic element module (220c) are inserted. The plurality of first insertion holes (260c) may be arranged between the first wiring (216c) and the second wiring (218c) and may be provided along the length direction of the first substrate (211c) at regular intervals.
[0106] The second substrate (221c) of the second electronic element module (220c) may be formed substantially identically to the first substrate (211c) of the first electronic element module (210c). Accordingly, the second substrate (221c) may be provided with a plurality of second insertion holes into which the tip portions (214c) of the plurality of first electronic elements (213c) are inserted.
[0107] When the first electronic element module (210c) and the second electronic element module (220c) are arranged with each other, the tip portions (224c) of the plurality of second electronic elements (223c) can be inserted into the plurality of first insertion holes (260c) provided in the first substrate (211c) of the facing first electronic element module (210c), and the tip portions (214c) of the plurality of first electronic elements (213c) can be inserted into the plurality of second insertion holes provided in the second substrate (221c) of the facing second electronic element module (220c).
[0108] Accordingly, the first electronic component module (210c) and the second electronic component module (220c) can be firmly fixed to each other without using an adhesive (400). Since the printed circuit board (100-4) can omit the process of applying the adhesive (400) among the manufacturing processes, the manufacturing time can be shortened and material costs can be reduced.

Accordingly, the second substrate (221d) may be provided with a plurality of second fixing grooves (262d) on which the tip portions (214d) of the plurality of first electronic elements (213d) are mounted.
[0115] The diameter of the plurality of first fixing grooves (261d) may be formed to be slightly smaller than or approximately the same as the diameter of the tip portions (224d) of the plurality of second electric elements (223d). Accordingly, the tip portions (224d) of the plurality of second electric elements (223d) may be firmly coupled to the plurality of first fixing grooves (261d) in a pressed state. Similarly, the diameter of the plurality of second fixing grooves (262d) may be formed to be slightly smaller than or approximately the same as the diameter of the tip portions (214d) of the plurality of first electric elements (213d).
