A first portion 611 or 612 of the first conductive line 610 disposed on the first region 610a may be spaced apart from a portion overlapping the first solders 650 when the printed circuit board 250 is viewed from above. For example, the first portion 611 or 612 may be bent to be spaced apart from a portion of the second non-conductive layer 312 overlapping the first solders 650 when the printed circuit board 250 is viewed from above. For example, the first portion 611 of the conductive pattern may include a meander line extending along a space (or an area) between the first solders 650 when the printed circuit board 250 is viewed from above. For example, the first portion 611 may not overlap the first solders 650 when the printed circuit board 250 is viewed from above. The first portion 611 may include a portion that may be bent within the first region 610a. The first portion 611 or 612 may be bent to be spaced apart from the portion overlapping the first solders 650. For example, the first portion 611 or 612 may extend in a straight line and then may be bent to maintain a designated distance range from one of the first solders 650. For example, as the first portion 611 or 612 is bent, the first portion 611 or 612 may be spaced apart from the one of the portions overlapping the first solders 650 in the second non-conductive layer 312 by the designated distance or more.

A joint by the first solders 650 may be a portion in which the stress is concentrated. Cracks in the printed circuit board 250 may occur at a portion joined to the first solders 650 in which the stress is concentrated. In an embodiment, in order to reduce a possibility of damage to the first conductive patterns 321 disposed under the first non-conductive layer 311 on which the first solders 650 are disposed, the first conductive patterns 321 may be spaced apart from a periphery of the first solders 650 by a designated distance or more.

According to an embodiment, the first conductive lines 610 are disposed in the first region 610a, but are not limited thereto. A portion 612 of one of the first conductive lines 610 may cross the first region 610a overlapping the interposer 330, and another portion 616 distinguished from the portion 612 may be disposed in a second region 610b distinguished from the first region 610a overlapping the interposer 330. For example, the portion 612 of one of the first conductive lines 610 may be bent several times in the first region 610a, and the other portion 616 of one of the first conductive lines 610 may extend in a straight line in the second region 610b.

According to an embodiment, the second conductive line 620 may be disposed in the second region 610b distinguished from the first region 610a on the second non-conductive layer 312. The second region 610b may be a region within a closed curve formed by the interposer 330. The second region 610b may be a region in which influence of stress concentration according to joining of the interposer 330 and the printed circuit board 250 is relatively small. For example, the second conductive line 620 disposed in the second region 610b may be a wiring that is difficult to adjust a width of the conductive line 620 or a length of the conductive line 620. For example, the second conductive line 620 may be a line in which impedance control is difficult. The second conductive line 620 may operate as an RF signal transmission line.

According to the above-described embodiment, when the printed circuit board
250 is viewed from above, the printed circuit board 250 may reduce damage to the first conductive lines 610 by disposing the first conductive lines 610 not to overlap the first solders 650. For example, when the printed circuit board 250 is viewed from above, in the case that the first conductive lines 610 are disposed across the first solders 650 in the first region 610a, the first conductive lines 610 in the region overlapping the first solders 650 may be damaged. In an embodiment, as the first conductive lines 610 are disposed between the first solders 650 and are disposed by avoiding the first solders 650, damage to the first conductive lines 610 may be reduced. By separating the second conductive line 620 (that may be relatively difficult to deform) from the overlapping region of the first solders 650, a possibility of damage to the second conductive line 620 may be reduced.

For example, a width d2 of the second portion 711 or 712 of the third conductive lines 710 disposed on the third region 710a may be wider than a width “d1” of the first portion 611 or 612 of the first conductive lines 610.
According to an embodiment, the second portion 711 or 712 in the third region 710a of the third conductive lines 710 may be thicker than a third portion 721 in a fourth region 710b. For example, the width “d2” of the third conductive lines 710 disposed on the third region 710a may be wider than a width “d3” of the third conductive lines 710 disposed in the fourth region 710b. As the third conductive lines 710 disposed on the third region 710a are disposed to overlap the second solders 750 among the plurality of solders 350, stress may be concentrated. To reduce damage from the concentrated stress, the second portion 711 or 712 of the third conductive lines 710 in the third region 710a may be formed to have relatively high rigidity.
According to an embodiment, a length “d2” corresponding to the width of the second portion 711 or 712 of the third conductive lines 710 disposed on the third region 710a may be longer than a width of the plurality of solders 350. For example, the length “d2” corresponding to a thickness of the second portion 711 or 712 of the third conductive lines 710 may be longer than a diameter ds of each of the plurality of solders 350. For example, the width of the second portion of the conductive pattern may be about 0.15 mm to 0.2 mm. The diameter of the solders may be about 0.02 mm to 0.15 mm.
According to an embodiment, the second portion 711 or 712 of the third conductive lines 710 may operate as a signal line or a power line.

In an embodiment, the first conductive lines 610 connected to the third conductive lines 710 may include the first portion 611 or 612. The first conductive lines 610 may be (e.g., meanderingly, in a twisting and turning way) disposed by avoiding the solders 350 in a region, and the third conductive lines 710 extending from the first conductive lines 610 may overlap the solders 350 in another region, and may be formed thick. The first conductive lines 610 may be spaced apart from portions overlapping the first solders 650 in the second non-conductive layer 312, and may be (e.g., meanderingly) extended between the portions overlapping the first solders 650. The third conductive lines 710 connected to the first conductive lines 610 may include the second portion 711 or 712. The third conductive lines 710 may overlap the second solders 750, and may have a width wider than that of another portion distinguished from the third portion 721. For example, the second portion 711 or 712 of the third conductive lines 710 may have a width thicker than a diameter of the second solders 750 in a region overlapping the second solders 750.
According to an embodiment, a portion of the first conductive lines 610 and the third conductive lines 710 may be (e.g., meanderingly) disposed by avoiding the solders 350, and another portion may overlap the solders 350 and have a relatively thick width. For example, the first conductive lines 610 of the first conductive lines 610 and the third conductive lines 710 may be (e.g., meanderingly) disposed by avoiding the solders 350 in the first region 610a, and the third conductive lines 710 may overlap the solders 350 in the third region 710a and have a relatively thick width.

However, the disclosure is not limited thereto. A conductive line of the portion of the first conductive lines 610 and the third conductive lines 710 may cross at least a portion of the first region 610a and at least a portion of the third region 710a. For example, a portion of the first conductive lines 610 may be connected to a portion of the third conductive lines 710.
According to the above-described embodiment, the printed circuit board 250 may reduce influence of a conductive pattern (e.g., the first conductive lines 610 and the third conductive lines 710) adjacent to the plurality of solders 350 by stress concentration caused based on joining of the plurality of solders 350. Among the conductive patterns disposed in the printed circuit board 250, the first conductive lines 610 overlapping a periphery of the interposer 330 may be disposed to avoid the solders 350 or may have a width wider than a diameter of each of the solders 350. The first conductive lines 610 disposed to avoid the solders 350 may reduce the influence of stress concentration. The first conductive lines 610 formed thicker than the solders 350 may reduce a possibility of cracks due to the stress concentration, by having relatively strong rigidity.

For example, the first conductive lines 610 may be (e.g., meanderingly) disposed by avoiding the solders 350 in a first region 610a, and may be electrically connected to the fourth conductive lines 810 through the conductive via 830. For example, the first conductive lines 610 have a thicker width than the solders 350 in a third region 710a, and may be electrically connected to the fourth conductive lines 810 through the conductive via 830.
According to an embodiment, the fifth conductive lines 820 may be configured to transmit a wireless communication signal from the processor 120 to an antenna 390. The fifth conductive lines 820 may cross the region 810a overlapping the plurality of solders 350 among the third non-conductive layer 313. For example, the fifth conductive lines 820 may be electrically connected to a second conductive line 620 of the first conductive pattern 321.
