將可拉伸的線路板應用於穿戴式裝置，可使穿戴式裝置對人體狀態的量測更精準，且使其更舒適地被使用者穿戴。然而，所述線路板的線路結構易因拉伸而損壞、斷裂，導致其電阻值急遽升高而影響其正常效能。Applying a stretchable circuit board to a wearable device can make the wearable device more accurate in measuring the state of the human body and make it more comfortable to be worn by the user. However, the circuit structure of the circuit board is easily damaged or broken due to stretching, resulting in a sudden increase in its resistance value and affecting its normal performance.

本發明提供一種線路板及電子裝置，使線路板的線路結構不易因線路板的拉伸而損壞、斷裂。The invention provides a circuit board and an electronic device, so that the circuit structure of the circuit board is not easily damaged or broken due to the stretching of the circuit board.

本發明的線路板包括一基板及至少一線路結構。基板具有多個第一開槽，各第一開槽沿一第一軸線延伸，各第一開槽沿第一軸線的長度大於各第一開槽沿其他方向的長度。線路結構配置於基板上且包括多個弧狀區段及多個延伸區段。各弧狀區段連接於兩延伸區段之間而使線路結構為迂迴狀。線路結構與各第一開槽之間具有間隙而使各第一開槽及基板的部分表面被線路結構暴露。各第一開槽位於相鄰的兩延伸區段之間，各第一開槽的第一軸線通過對應的弧狀區段。The circuit board of the present invention includes a substrate and at least one circuit structure.

There is a gap between the circuit structure and each of the first slots, so that each of the first slots and part of the surface of the substrate are exposed by the circuit structure.

本發明的電子裝置包括一線路板及兩電子元件。線路板包括一基板及至少一線路結構。基板具有多個第一開槽，各第一開槽沿一第一軸線延伸，各第一開槽沿第一軸線的長度大於各第一開槽沿其他方向的長度。線路結構配置於基板上且包括多個弧狀區段及多個延伸區段。各弧狀區段連接於兩延伸區段之間而使線路結構為迂迴狀。線路結構與各第一開槽之間具有間隙而使各第一開槽及基板的部分表面被線路結構暴露。各第一開槽位於相鄰的兩延伸區段之間，各第一開槽的第一軸線通過對應的弧狀區段。兩電子元件藉由線路板而彼此電性連接。The electronic device of the present invention includes a circuit board and two electronic components. The circuit board includes a substrate and at least one circuit structure. The substrate has a plurality of first slots, each of the first slots extends along a first axis, and the length of each first slot along the first axis is greater than the length of each first slot along other directions. The circuit structure is disposed on the substrate and includes a plurality of arc sections and a plurality of extension sections. Each arc-shaped section is connected between the two extension sections to make the circuit structure in a circuitous shape. There is a gap between the circuit structure and each of the first slots, so that each of the first slots and part of the surface of the substrate are exposed by the circuit structure. Each first slot is located between two adjacent extension sections, and the first axis of each first slot passes through the corresponding arc-shaped section. The two electronic components are electrically connected to each other through the circuit board.

基於上述，在本發明的線路板中，線路結構與基板的開槽之間具有間隙，亦即，線路結構並非完全覆蓋基板的表面，而是僅覆蓋基板的部分表面，使得線路結構不會過於鄰近基板的第一開槽。如此一來，當線路板被拉伸時，基板的第一開槽的末端產生的應力集中不會直接傳遞至線路結構，而可有效避免線路結構因線路板的拉伸而損壞、斷裂。此外，第一開槽的延伸軸線(即所述第一軸線)通過對應的弧狀區段，使得弧狀區段鄰近第一開槽的末端，從而可藉由無尖角的弧狀區段來進一步降低應力集中的程度。Based on the above, in the circuit board of the present invention, there is a gap between the circuit structure and the slot of the substrate, that is, the circuit structure does not completely cover the surface of the substrate, but only covers part of the surface of the substrate, so that the circuit structure is not too much. The first slot adjacent to the substrate. In this way, when the circuit board is stretched, the stress concentration generated at the end of the first slot of the substrate will not be directly transmitted to the circuit structure, and the circuit structure can be effectively prevented from being damaged or broken due to the stretching of the circuit board. In addition, the extension axis of the first slot (that is, the first axis) passes through the corresponding arc-shaped section, so that the arc-shaped section is adjacent to the end of the first slot, so that the arc-shaped section without sharp corners can be used. To further reduce the degree of stress concentration.

為讓本發明的上述特徵能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。In order to make the above-mentioned features of the present invention more obvious and comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

圖1是本發明一實施例的線路板的俯視圖。圖2是圖1的線路板的局部放大圖。請參考圖1及圖2，本實施例的線路板100包括一基板110及至少一線路結構120(繪示為多個)。基板110具有多個第一開槽110a，各第一開槽110a沿一第一軸線A1延伸，各第一開槽110a沿第一軸線A1的長度大於各第一開槽110a沿其他方向的長度。各線路結構120配置於基板110上且包括多個弧狀區段122及多個延伸區段124。各弧狀區段122連接於兩延伸區段124之間而使線路結構120為迂迴狀，各第一開槽110a位於相鄰的兩延伸區段124之間。線路板100可藉由這些第一開槽110a及這些弧狀區段122的變形而沿垂直於第一軸線A1的方向X被拉伸，據以提供一維的拉伸效果。Fig. 1 is a top view of a circuit board according to an embodiment of the present invention. Fig. 2 is a partial enlarged view of the circuit board of Fig. 1. Please refer to FIG. 1 and FIG. 2, the circuit board 100 of this embodiment includes a substrate 110 and at least one circuit structure 120 (multiple are shown). The substrate 110 has a plurality of first slots 110a, and each first slot 110a extends along a first axis A1, and the length of each first slot 110a along the first axis A1 is greater than the length of each first slot 110a along other directions . Each circuit structure 120 is disposed on the substrate 110 and includes a plurality of arc-shaped sections 122 and a plurality of extension sections 124. Each arc-shaped section 122 is connected between the two extending sections 124 so that the circuit structure 120 has a roundabout shape, and each first slot 110 a is located between two adjacent extending sections 124. The circuit board 100 can be stretched along the direction X perpendicular to the first axis A1 by the deformation of the first slots 110a and the arc-shaped sections 122, so as to provide a one-dimensional stretching effect.

如圖1及圖2所示，線路結構120與基板110的各第一開槽110a之間具有間隙而使各第一開槽110a及基板110的部分表面被線路結構120暴露。亦即，線路結構120並非完全覆蓋基板110的表面，而是僅覆蓋基板110的部分表面，使得線路結構120不會過於鄰近基板110的第一開槽110a。如此一來，當線路板110被拉伸時，基板110的第一開槽110a的末端產生的應力集中不會直接傳遞至線路結構120，而可有效避免線路結構120因線路板110的拉伸而損壞、斷裂。As shown in FIGS. 1 and 2, there is a gap between the circuit structure 120 and each of the first grooves 110 a of the substrate 110, so that each of the first grooves 110 a and part of the surface of the substrate 110 are exposed by the circuit structure 120. That is, the circuit structure 120 does not completely cover the surface of the substrate 110, but only covers a part of the surface of the substrate 110, so that the circuit structure 120 is not too close to the first slot 110a of the substrate 110. In this way, when the circuit board 110 is stretched, the stress concentration generated at the end of the first slot 110a of the substrate 110 will not be directly transmitted to the circuit structure 120, and the circuit structure 120 can be effectively prevented from being stretched by the circuit board 110. And damaged, broken.

此外，在本實施例中，各第一開槽110a的延伸軸線(即第一軸線A1)通過對應的弧狀區段122，使得弧狀區段122鄰近第一開槽110a的末端，從而可藉由無尖角的弧狀區段122來進一步降低應力集中的程度。In addition, in this embodiment, the extension axis (ie, the first axis A1) of each first slot 110a passes through the corresponding arc section 122, so that the arc section 122 is adjacent to the end of the first slot 110a, so that the The arc-shaped section 122 without sharp corners further reduces the degree of stress concentration.

在本實施例中，基板110的各第一開槽110a例如是狹縫而為直線形開槽，線路結構120的各延伸區段124是沿直線方向延伸，且各相鄰的兩延伸區段124相互平行。各第一開槽110a沿第一軸線A1的長度L與相鄰的兩第一開槽110a沿垂直於第一軸線A1的方向的距離x的比值L/x例如大於5，以維持穩定的拉伸特性。In this embodiment, each first slot 110a of the substrate 110 is, for example, a slit instead of a linear slot, each extension section 124 of the circuit structure 120 extends along a straight direction, and each of two adjacent extension sections 124 are parallel to each other. The ratio L/x between the length L of each first slot 110a along the first axis A1 and the distance x between the two adjacent first slots 110a along the direction perpendicular to the first axis A1 is, for example, greater than 5, so as to maintain stable tension.

As shown in FIG. 5, the linear first slots 110a3 and 110a4 that intersect each other have extending directions perpendicular to each other to provide a two-dimensional stretching effect. As shown in FIG. 6, the linear first slots 110a5, 110a6 that do not intersect each other have their extending directions perpendicular to each other to provide a two-dimensional stretching effect. As shown in FIGS. 7 and 8, the linear first grooves 110a7 and 110a8 that intersect each other have different extension directions and are inclined to provide a two-dimensional stretching effect. The difference between FIG. 8 and FIG. 7 is that: More first slots 110a7 and 110a8 in FIG. 8 are connected in sequence to form a continuous slot structure. In other embodiments, the first slot may be a rectangular slot, a hexagonal slot or other shapes of slots, which is not limited in the present invention.

表1The following table 1 (results of stretching once) compares the plastic strain, the initial resistance, and the resistance change rate based on the initial resistance in the embodiment shown in FIG. 14 and the embodiment shown in FIG. Compare the calculation results of the simulation software.

Table 1

如上列表1所示，圖14所示實施例的第一開槽710a的長度與相鄰的兩第一開槽710a的距離的比值L/x(如同前述的比值L/x)相同於圖15所示實施例的所述比值，例如皆為10。此外，圖14所示實施例及圖15所示實施例的沿方向Y的第一開槽710a的數量例如皆為6.5個。在此前提之下，基於圖14所示實施例的所述填滿配置方式與圖15所示實施例的所述未填滿配置方式之差異，圖14的線路板700於拉伸時的最大塑性應變為1.55%，低於圖15的線路板700於拉伸時的最大塑性應變為4.91%。並且，圖14的線路板700的初始電阻為21.18Ω，高於圖15的線路板700的初始電阻為13.40Ω。此外，圖14的線路板700於拉伸時的電阻變化率為1.42%，高於圖15的線路板700於拉伸時的電阻變化率為0.12%。As shown in Table 1 above, the ratio L/x (like the aforementioned ratio L/x) of the length of the first slot 710a of the embodiment shown in FIG. 14 and the distance between two adjacent first slots 710a is the same as that of FIG. 15 The ratios of the illustrated embodiment are all 10, for example. In addition, the number of the first grooves 710a along the direction Y in the embodiment shown in FIG. 14 and the embodiment shown in FIG. 15 are, for example, 6.5. Under this premise, based on the difference between the filled configuration mode of the embodiment shown in FIG. 14 and the unfilled configuration mode of the embodiment shown in FIG. 15, the circuit board 700 of FIG. The plastic strain is 1.55%, which is lower than the maximum plastic strain of 4.91% when the circuit board 700 in FIG. 15 is stretched. In addition, the initial resistance of the wiring board 700 in FIG. 14 is 21.18Ω, which is higher than the initial resistance of the wiring board 700 in FIG. 15 being 13.40Ω. In addition, the resistance change rate of the circuit board 700 when stretched in FIG. 14 is 1.42%, which is higher than the resistance change rate of the circuit board 700 when stretched in FIG. 15 is 0.12%.

圖16是本發明另一實施例的線路板的俯視圖。圖17是圖16的線路板的局部放大圖，其中圖17對應於圖16的區域R1。在圖16及圖17所示實施例中，基板810及其第一開槽810a與線路結構820的配置與作用方式類似前述實施例的基板及其第一開槽與線路結構的配置與作用方式，於此不再贅述。圖16及圖17所示實施例與前述實施例的不同處在於，線路板800更包括多個連接線路860，各連接線路860連接於兩線路結構820之間而使這些線路結構820及這些連接線路860共同構成迂迴狀結構。基板810更具有多個第二開槽810b，各第二開槽810b位於相鄰的兩線路結構820之間，各第二開槽810b沿垂直於第一軸線A1的一第二軸線A2延伸。線路板800可藉由這些第二開槽810b及這些連接線路860的變形而沿垂直於第二軸線A2的方向被拉伸。也就是說，在圖16及圖17所示實施例中，除了各線路結構820自身如圖17所示為迂迴狀而可配合第一開槽810a提供方向X的拉伸效果，多個線路結構820及多個連接線路860亦共同構成迂迴狀結構，而可配合第二開槽810b提供方向Y的拉伸效果。Fig. 16 is a top view of a circuit board according to another embodiment of the present invention. FIG. 17 is a partial enlarged view of the circuit board of FIG. 16, wherein FIG. 17 corresponds to the area R1 of FIG. 16. In the embodiment shown in FIGS. 16 and 17, the configuration and function of the substrate 810 and its first slot 810a and the circuit structure 820 are similar to the configuration and function of the substrate and its first slot and circuit structure of the previous embodiment. , I won’t repeat it here. The embodiment shown in FIG. 16 and FIG. 17 is different from the previous embodiment in that the circuit board 800 further includes a plurality of connection lines 860, and each connection line 860 is connected between two line structures 820 so that these line structures 820 and these connections The lines 860 together form a circuitous structure. The substrate 810 further has a plurality of second slots 810b, each of the second slots 810b is located between two adjacent circuit structures 820, and each of the second slots 810b extends along a second axis A2 perpendicular to the first axis A1. The circuit board 800 can be stretched in a direction perpendicular to the second axis A2 by the deformation of the second slots 810b and the connecting lines 860. That is to say, in the embodiment shown in FIG. 16 and FIG. 17, in addition to the circuit structure 820 itself as shown in FIG. 17, the circuit structure can cooperate with the first slot 810a to provide a stretching effect in the direction X. 820 and a plurality of connecting lines 860 also jointly form a circuitous structure, which can cooperate with the second slot 810b to provide a stretching effect in the direction Y.

圖18繪示本發明一實施例的線路板經拉伸測試所得的電阻變化率，其測試條件為拉伸量10%及拉伸時間為6000秒內(1000次重複拉伸測試)，且其例如對應於類似圖14所示的線路板700。如圖18所示，本發明之實施例的線路板經過長時間拉伸後，其電阻變化率維持在5%以下，由此可知，本發明之實施例藉由將線路結構設計為非完全覆蓋基板的表面，可有效降低其被拉伸時的電阻變化率。FIG. 18 shows the resistance change rate of a circuit board obtained by a tensile test according to an embodiment of the present invention. The test condition is that the tensile amount is 10% and the tensile time is within 6000 seconds (1000 repeated tensile tests), and For example, it corresponds to a circuit board 700 similar to that shown in FIG. 14. As shown in FIG. 18, the circuit board of the embodiment of the present invention has a resistance change rate of less than 5% after being stretched for a long time. It can be seen that the embodiment of the present invention designs the circuit structure to not completely cover The surface of the substrate can effectively reduce the resistance change rate when it is stretched.

圖19是本發明一實施例的電子裝置的示意圖。如圖19所示，兩電子元件52、54可藉由上述實施例的線路板100而彼此電性連接，從而構成電子裝置50。電子裝置50例如是穿戴式電子裝置，而兩電子元件52、54可為所述穿戴式電子裝置的人體狀態量測元件、資訊顯示元件或其他種類的元件，本發明不對此加以限制。在其他實施例中，兩電子元件52、54可藉由上述其他任一實施例的線路板而彼此電性連接，本發明不對此加以限制。FIG. 19 is a schematic diagram of an electronic device according to an embodiment of the invention. As shown in FIG. 19, the two electronic components 52 and 54 can be electrically connected to each other through the circuit board 100 of the above-mentioned embodiment, thereby forming an electronic device 50. The electronic device 50 is, for example, a wearable electronic device, and the two electronic components 52, 54 can be human body state measuring components, information display components or other types of components of the wearable electronic device, and the present invention is not limited thereto. In other embodiments, the two electronic components 52 and 54 can be electrically connected to each other via the circuit board of any of the other embodiments described above, and the present invention is not limited thereto.

本發明不對線路板的相鄰兩開槽之間的線路結構數量加以限制，以下以圖11所示線路板400為例對此加以說明。圖20是圖11的線路板的局部放大圖，其中圖20對應於圖11的區域R2。如圖20所示，兩線路結構420並列且延伸於相鄰的兩第一開槽410a之間。在其他實施例中，可將更多數量的線路結構並列且延伸於相鄰的兩第一開槽410a之間，本發明不對此加以限制。The present invention does not limit the number of circuit structures between two adjacent slots of the circuit board. The circuit board 400 shown in FIG. 11 is taken as an example to describe this in the following. FIG. 20 is a partial enlarged view of the circuit board of FIG. 11, wherein FIG. 20 corresponds to the area R2 of FIG. 11. As shown in FIG. 20, two circuit structures 420 are arranged side by side and extend between two adjacent first slots 410a. In other embodiments, a larger number of circuit structures can be arranged in parallel and extend between two adjacent first slots 410a, which is not limited in the present invention.

圖21是圖22的線路板沿II-II線的剖面圖。為使圖式較為清楚，圖21以簡略的方式示意性地繪示線路結構420。線路板400更包括一保護層440，保護層440的材質例如皆為絕緣材料，其配置於基板410上而遮蔽線路結構420，避免線路結構420直接接觸外界物體而損壞。圖21的保護層440與圖13的保護層640的不同處在於，保護層440直接覆蓋於基板410及線路結構420上，而非如同圖13的保護層640藉由支撐結構650而被撐離於基板610及線路結構620。此外，圖21的保護層440可具有第三開槽440a，用以提供可拉伸效果。Fig. 21 is a cross-sectional view of the circuit board of Fig. 22 along line II-II. To make the drawing clearer, FIG. 21 schematically depicts the circuit structure 420 in a simplified manner. The circuit board 400 further includes a protective layer 440. The protective layer 440 is made of, for example, an insulating material. The protective layer 440 is disposed on the substrate 410 to shield the circuit structure 420 and prevent the circuit structure 420 from directly contacting external objects and being damaged. The protection layer 440 of FIG. 21 is different from the protection layer 640 of FIG. 13 in that the protection layer 440 directly covers the substrate 410 and the circuit structure 420, instead of being supported by the support structure 650 like the protection layer 640 of FIG. On the substrate 610 and the circuit structure 620. In addition, the protective layer 440 of FIG. 21 may have a third slot 440a to provide a stretchable effect.
