At the same time, it often increases the cost of materials. In view of this, it is necessary to provide a flexible circuit board which is low in cost and has good tearability. SUMMARY OF THE INVENTION A flexible circuit 6 200847863 board having good flexibility is described below by way of example. A flexible circuit board, a complex circuit, the working circuit at the bottom of the circuit and the working flexible circuit board formed on the substrate further comprises: 侔;;= into the working line area, the 1 丨木 reinforcing line, Lifei 屮Recognize – outside the work area area. , on the soil floor and distributed - a flexible circuit board comprising a substrate, the substrate comprising I as a μ zone. The peripheral circuit of the working circuit formed on the substrate is formed in a peripheral region of the substrate. ^ or inside, the reinforcing line of the flexible circuit board, the abdomen, the external, therefore, when the soft handle sister: / is placed in the working line area, the strong line will effectively withstand the f-fold process bowing the day to keep this, when soft, When the board is subjected to a large degree of bending, or: the line fails due to the presence of the reinforcing line without breaking. ::: The setting of the line can effectively improve the softness of the flexible circuit board. (4) It can also improve the service life of the flexible circuit board. [Embodiment] Hereinafter, a soft % road board of the present technical solution will be further described in detail with reference to the accompanying drawings and a plurality of embodiments. As shown in "1, the present technology (4) first - implementation difficult to provide - the board (10), including the base 110, the working line 121 and the reinforcing line 130. The working line 121 and the reinforcing line 130 are formed on the substrate 11〇, and the working line m纟 is formed on the substrate 110—the working line area 12〇. All of the working lines 121 on the substrate 7 200847863 110 are within the working line area 120. Accordingly, the substrate 110 includes two regions, i.e., the working circuit region 120 and the peripheral region surrounding the working circuit region 120 (not shown). The reinforcing circuit 130 is formed in the peripheral region. Preferably, the working line regions 120 are distributed in a central region of the substrate 110, and the reinforcing wires 130 are distributed on both sides of the working circuit region 120 along the length of the substrate 110.
工作線路121在軟性電路板100工作過程中用於電訊 號之傳輸，而補強線路130在軟性電路板100工作過程中 不會進行電訊號傳輸。當軟性電路板100發生彎折時，補 強電路130會對由於軟性電路板100之彎折所產生之剪切 力進行較大程度之承載，從而較大程度地分擔工作線路121 上所承載之剪切力。 由於軟性電路板100使用過程中通常要經受較多次之 反復彎折，因此部分工作線路121會因過複數次之彎折而 斷裂失效。經過多方面研究發現，軟性電路板100上發生 斷裂之工作線路121通常為處於邊緣之工作線路，例如處 於最邊緣之工作線路以及處於倒數第二邊緣之工作線路。 即，在軟性電路板100彎折過程中，處於邊緣之工作線路 所承受之剪切力較大，因此在反復彎折之情況下，邊緣部 位之工作線路常常存在斷裂之隱患。因此，本實施例中， 補強線路130沿基底110之長度方向設置在工作線路區域 120之兩侧且靠近基底邊緣之區域，這樣當軟性電路板100 經受較多次之反復彎折時，特別係軟性電路板100沿基底 110之長度方向發生反復彎折時，補強線路130會承載較大 8 200847863 ‘部分之剪切力，這樣在很大程产 小 -承受之剪切力，從而可避免工作又線路^工作線路121上所 發生彎折時發生斷裂。 、7 1在軟性電路板100 補強線路130之材質可 等其他合適之材料。補強線路 ' :屬，例如銅、金、銀 處於最外側之工作線路之間之距離、工作線路區域GO内 10毫米。補強線以30之寬度大於，1大於零小於或等於 優選地，補強線路13〇之^大纟^小於或等於〇.5毫米， •本實施例中，補強線路：〇、為雨“:5毫f。 作線路121為工作線路巴 ”、、、條銅材質之直線，工 強線…之内Λ於最外側之線路’補 強線路130之線寬為〇 。 約1毫米，且補 如圖2所示，本枯讲〜 電路板200,其包括基底二1〇了^ =實施例提供另一種軟性 路區域220以及補強線路工/線路221形成之工作線 • 200結構與第—實 〇°弟二實施例之軟性電路板 ，之處為：所述補強線路23=電路板100基本相同，所不同 其分別沿基底21G之長/^料折"?^浪狀之曲線， 外側，且該非直線型之非列在工作線路區域伽之 ^ 22〇 唉a Λ ^ 岭之間之最小距離D2大於费 米。例如工作線路221為處於 路;:於或 ::外側之線路，彎折狀或波浪狀之補強線路2=220 所如之間之最小距離D2大於零小於或等二工作 所述補強線路⑽之寬度大於零小於或等於〇5〇n 水’優選 9 200847863 地，補強線路130之寬度大約〇1〜〇 5毫米。 本技術方案之軟性電路板 例所描述之情況，例如補強線 型、彎折型或波浪型；亦可為孤形上述直線 ' 卜補強線路之形狀可為目案結構，如多^ 橢圓型或其他規則或不規則此如^开广 直線型、曲線型或者圖宰型補強此外，對於上述 =4:具Γ線路亦可為非連續狀，例如，補強線 =了干個長度較短之銅線段間隔排列成之直線、曲線 參閱圖3，提供一捕綠始？々& π 補強線路為圖案結構 3〇〇，，第-實施例之軟性電路板⑽基= 線路330之形狀為矩形。矩形補強線路 320 =外；路：域320内之邊331與處於工作線路區域 320内取外側之工作線路321之間之距離& 成 1毫米。補強線路330之寬度盥第—趣 …；令小於 之寬度相同。 4以例之補強線路130 以第一實施例為例，在軟性電路板⑽巾 130沿基底110之長度方向設置在工作線路區域120 = 側，因此，當軟性電路板100經受較 之兩 特別係軟性電路板100沿基底110之長度方向：::：1 折時，補強線路1301有效承受彎折過程所產生之剪t?、 從而可在很大程度上分擔工作線路區_ 120中之 ， 受之剪切力。因此’由於補強線路130對剪切力之保= 10 200847863 ，用’當軟性電路板100即便經受更大程度彎折時，工 ‘路區域120中之線路亦不會發生斷裂而失效。故，本實施 例之軟性電路板100結構中，補強線路m之設置可有效 提升軟性電路板⑽可彎折之程度，同時亦可提升軟性: 路板100之使用壽命。同樣，軟性電路板2〇〇、具有= 軟性電路板100相同或相似之技術效果。 /、 下面以軟性電路板100之έ士播焱^ I 構為例，補強線路為鋼直 泉，且補強線路到最外側工作線路之距離為丄毫米， ' :路之寬度在0-0.5毫米之範圍内變化。在上述條件相同之 ?兄下，當工作線路之線寬取丄毫米時，補強線路之寬度 二i: 0 〇·1 ’ 0.2 ’ 0·3 ’ 0·4 ’ 〇·5 毫米時，可得到 6 個： 〜構之軟性電路板，對該6個軟性電路板之撓折性（軟性 電路板從開始彎折到線路折斷所經受之彎折次數）能進行測 如圖4所示’建立坐標系，橫坐標表示補強線路之寬 度二縱坐標表示軟性電路板折斷所經受之f折次數，這# ps可得到撓折性隨補強線路寬度變化之曲線A。 水 0 25 Π當I作線路之線寬取3mil(㈣，1密爾約等於 .微未）日守候，補強線路之寬度分別取0，（U，0.2，0 3， 〇.4 0.5毛米日寸，可得到另外6個不同結構 對該:、個軟性電路板之挽折性能進行測試，這樣可H 折1"生Ik補強線路寬度變化之曲線B。 ,從圖4之變化趨勢來看，無論工作線路之線寬取工毫 米亦或3mi卜隨著補強線路寬度之增加’軟性電路板之二 折性會隨之提高。而當補強線路寬度為亳米時，軟性^ 11 200847863 •路板之撓折性增加的幅度最大，而當 〇5套半眭，私伸強線路寬度增加至 ^ /、 权性龟路板之撓折性增加不明顯。纟，檢力 補強線路可提高軟性電路板之撓折性，、U曰 補強岣改π你从U 而增加不同寬度之 泉路了使权性電路板之撓折性得到不同程度地提古。 綜上所述，本發明確已符合發明 又地楗阿 提出Iw a專利之要件，遂依法 式=!，。惟’以上所述者僅為本發明之較佳實施方 自不此以此限制本案之申請專利範圍。舉凡熟悉本案 技蟄之人士援依本發明之精神所作 、、心 ” _ Λ 寺效修飾或變化，皆 w 现於以下申請專利範圍内。 圖 圖式簡單說明】 圖1係本技術方案第一實施例之軟性 電路板結構示意 圖。 圖2係本技術方案第二實施例之軟性 電路板結構示意 圖 圖3係本技射案第三實_之軟性電路板結構示意 生變L:電路板之撓折性隨補強線路寬度變化而發 、主要元件符號說明 軟性電 路板 工作線 100 ， 200 ， 300 基底 110 ， 210 ， 310 路區域 120 ， 220 ， 320 工作線路121，221，321 12 200847863 331 補強線路130，230，330 内邊 13The working circuit 121 is used for the transmission of the electrical signal during the operation of the flexible circuit board 100, and the reinforcing circuit 130 does not perform the electrical signal transmission during the operation of the flexible circuit board 100. When the flexible circuit board 100 is bent, the reinforcing circuit 130 carries a large degree of load on the shearing force generated by the bending of the flexible circuit board 100, thereby largely sharing the shears carried on the working circuit 121. Cutting force. Since the flexible circuit board 100 is usually subjected to repeated bending more than a plurality of times during use, the partial working line 121 may fail due to the bending of the plurality of times. It has been found through various studies that the working circuit 121 that is broken on the flexible circuit board 100 is usually the working circuit at the edge, such as the working circuit at the outermost edge and the working circuit at the penultimate edge. That is, in the bending process of the flexible circuit board 100, the working force on the edge of the working circuit is subjected to a large shearing force. Therefore, in the case of repeated bending, the working line of the edge portion often has a hidden danger. Therefore, in this embodiment, the reinforcing lines 130 are disposed along the length direction of the substrate 110 on both sides of the working line region 120 and close to the edge of the substrate, so that when the flexible circuit board 100 is subjected to repeated bending repeatedly, the special system When the flexible circuit board 100 is repeatedly bent along the length direction of the substrate 110, the reinforcing circuit 130 will carry a large portion of the shear force of the 200847863' portion, so that the shear force is large in a large process, thereby avoiding work. When the line ^ working line 121 is bent, a break occurs. 7, 7 in the flexible circuit board 100 reinforcing line 130 material can be other suitable materials. Reinforcement line ' : genus, such as copper, gold, silver, the distance between the outermost working lines, 10 mm within the working line area GO. The reinforcing line is greater than the width of 30, and 1 is greater than zero is less than or equal to. Preferably, the reinforcing line 13 is less than or equal to 〇5 mm. In this embodiment, the reinforcing line: 〇, is rain ": 5 The line 121 is the straight line of the working line bar ",", the strip copper material, and the line width of the reinforcing line 130 within the line of the work line... About 1 mm, and as shown in Fig. 2, the circuit board 200, which includes the substrate 2, is provided with another soft path region 220 and a working line formed by the reinforcing line/line 221. 200 structure and the first embodiment of the soft circuit board of the second embodiment, the reinforcing circuit 23 = the circuit board 100 is basically the same, the difference is different along the length of the base 21G / "; The wave-shaped curve, the outer side, and the non-linear type is not listed in the working line area. The minimum distance D2 between the ridges is greater than Fermi. For example, the working line 221 is in the road; the line on the or :: outer side, the bent line or the wavy reinforcing line 2=220, such as the minimum distance D2 is greater than zero less than or equal to the work of the reinforcing line (10) The width is greater than zero less than or equal to 〇5〇n water 'preferably 9200847863, the width of the reinforcing line 130 is about 〇1~〇5 mm. The case described in the flexible circuit board example of the technical solution, for example, the reinforcing line type, the bending type or the wave type; or the shape of the above-mentioned straight line 'b reinforcing line can be the structure of the object, such as multi-elliptic type or other Rule or Irregularity This is a straight line type, curve type or figure type reinforcement. In addition, for the above =4: the Γ line may also be discontinuous, for example, the reinforcement line = dry copper line segments of shorter length The lines are arranged in a straight line, and the curve is shown in Figure 3. What is the beginning of a green catch? The 々& π reinforcing line is a pattern structure. That is, the flexible circuit board (10) base of the first embodiment = the shape of the line 330 is a rectangle. The rectangular reinforcing line 320 = outer; the distance between the side 331 in the field 320 and the working line 321 taken outside the working line area 320 is & 1 mm. The width of the reinforcing line 330 is the first - interesting ...; the width is less than the same width. 4, for example, the reinforcing circuit 130 is exemplified in the first embodiment, in which the flexible circuit board (10) towel 130 is disposed along the length direction of the substrate 110 on the working line region 120 = side, and therefore, when the flexible circuit board 100 is subjected to two special systems When the flexible circuit board 100 is folded along the length direction of the substrate 110 by ::::1, the reinforcing circuit 1301 can effectively withstand the shearing caused by the bending process, so that the working circuit area _ 120 can be largely shared. Shear force. Therefore, since the reinforcing circuit 130 protects the shearing force = 10 200847863, when the flexible circuit board 100 is subjected to a greater degree of bending, the line in the work area 120 does not break and fails. Therefore, in the structure of the flexible circuit board 100 of the embodiment, the setting of the reinforcing circuit m can effectively improve the degree of bending of the flexible circuit board (10), and at the same time improve the softness: the service life of the road board 100. Similarly, the flexible circuit board 2 has the same or similar technical effects as the flexible circuit board 100. /, Take the soft board 100's gentleman's broadcast 焱 ^ I structure as an example, the reinforcing line is steel straight spring, and the distance from the reinforcing line to the outermost working line is 丄 mm, ' : the width of the road is 0-0.5 mm Changes within the scope. Under the above-mentioned conditions, when the line width of the working line is 丄 mm, the width of the reinforcing line is two i: 0 〇·1 ' 0.2 ' 0·3 ' 0·4 ' 〇 · 5 mm 6: ~ The flexible circuit board, the flexibility of the 6 flexible circuit boards (the number of bends that the flexible circuit board is subjected to bending from the start to the line break) can be measured as shown in Figure 4. The abscissa indicates the width of the reinforcing line. The ordinate indicates the number of f-folds experienced by the flexible circuit board. This # ps can obtain the curve A of the flexural change with the width of the reinforcing line. Water 0 25 Π When I line the line width is 3mil ((4), 1 mil is equal to. Micro is not) day waiting, the width of the reinforcing line is taken as 0, (U, 0.2, 0 3, 〇.4 0.5 m米In the day, you can get another 6 different structures to test: the flexural performance of a flexible circuit board, so that H can be folded 1 " raw Ik to strengthen the line width curve B. From the trend of Figure 4 Regardless of the line width of the working line, or the 3mi pad, the width of the flexible circuit board will increase with the increase of the width of the reinforcing circuit. When the width of the reinforcing line is 亳米, soft ^ 11 200847863 • Road The flexural increase of the board is the largest, and when the set of 5 sets is half-turned, the width of the private extension line is increased to ^ /, and the flexurality of the weight turtle board is not obvious. 纟, the force-reinforcing line can improve the softness. The flexibility of the circuit board, U 曰 reinforced tampering π you increase the width of the spring from the U to make the flexibility of the flexible circuit board to a different degree.
