九、發明說明： 【發明所屬之技術領域】 本發明係有關將局部具有凸出部之大致平坦的 優良的密接度貼附於平坦之基材上的貼附裝置。 【先前技術】 在基材的表面上隔著黏著層而貼附薄片的方法 合製品的實用機能或形態而逐漸地被開發。例如， 專利特開平7 — 272625號公報（專利文獻1 )所介紹 運送玻璃球管，一面在其有微細凹凸的表面上用橡 加壓平坦的PET (聚對苯二甲酸乙二酵酯）等的樹脂 抑制抱進氣泡或異物及薄片之皺紋的產生等的貼附 在此例中，做了使裝置於輥子上之橡膠能吸收貼附 球管的面之凹凸或曲率的設計。據此，暗示著若輥 膠的硬度過高，則在寬度方向之端部會抱進氣泡或 紋，不僅黏著強度甚至被覆後的透明度都無法確保 一例子，而介紹了寬度250mm之球管一面以分速 運送，一面將厚度爲20/zm的聚氨酯薄片隔著40// 著層，利用表面硬度爲50以下且厚度10mm之橡膠 加55Kg以上（寬度方向的接觸線壓爲2.2 kg/cm 的負載之貼附手段。 在日本專利特開平6 — 5572 1號公報（專利文膚 揭示有在人造大理石上隔著摻入有天然石粉之樹脂 置相片，並在其上面用透明的樹脂層被覆之製造裝 片的人造石裝飾品之方法。而爲了通過透明樹脂層 薄片以 ，係配 在日本 ，一面 膠輥子 薄片， 手段。 薄片之 子之橡 產生皺 。作爲 1 800mm m的黏 輥子施 以上） 層而載 入有相 能明顯 200827161 地看到相片的畫像，有需要使該樹脂層上未殘留氣泡。因 此，使樹脂層硬化之際，將塗抹有樹脂層之裝入相片的工 件放置在印刷台上，把貼有可撓性薄片之框體推抵於其塗 . 抹面，透過以加壓輥子在其上面印刷而脫出氣泡。在那時， - 框體的周端部係透過印刷台的吸引孔而從外部真空排氣。 因此，薄片在工件上的樹脂層，成爲像將此包住一樣地密 接同時從該樹脂層促進氣泡脫出的構造。 I 又，在日本專利特開2005 - 1 635 3 8號公報（專利文獻 3 )，介紹有在坑道內之混凝土壁上隔著紫外線硬化型的黏 著層加襯纖維強化塑膠（FRP)薄片時，把殘留在貼合界面之 氣泡除去的手段。例如，揭示有預先在薄片上貼附剝離薄 片，從其上方用輥子一面加壓使氣泡脫出而一面使黏著層 硬化，之後將剝離薄片剝離的工法。 專利文獻1 :日本專利特開平7 — 272625號公報 專利文獻2 :日本專利特開平6 - 5572 1號公報 _ 專利文獻3 :日本專利特開2005 — 1 63 5 3 8號公報 【發明內容】 【發明所欲解決之課題】 如同以上的例子，在貼附薄片以保護製品時，有需要 提高薄片對基材的密接性（使雙方之貼附界面無間隙而接 觸之性能）。又，把薄片貼附於基材面後，在其上方形成 規定厚度之電子電路或印刷顯示等機能部的情況也是同 樣。不論何種情況，在基材與薄片的界面能使未殘留氣泡， 200827161 再者由於貼附時之伸縮會在事後恢復，因而不使薄片從基 材浮上乃重要之事。此外密接性的好壞，例如，係受到面 的起伏、吸附的水分或汚髒等之基材與薄片的表面形態所 左右，對於貼附後之製品的實用機能或其持續性會有大的 影響。 習知爲了逐出氣泡或避免薄片伸縮後之恢復，被推薦 之手段有如以上的專利文獻所揭示，乃係利用輥子進行均 勻加壓。然而，其大部分爲貼附於平坦之薄片的事例。例 如，在專利文獻1暗示有靈活地改變順應薄片表面起伏之 輥子的橡膠硬度或厚度的手段。可是該手段在薄片上有部 分起伏的情況，難以使貼附後之薄片的面大致平坦。專利 文獻2及3的手段也是薄片無起伏的情況，可說與專利文 獻1相同。本發明之課題係提供一種貼附裝置，其可在即 使是把要貼附面是大致平坦但局部具有其厚度之5至30% 之高度的凸出部的薄片貼附於平坦的基材面時，在黏貼的 界面不殘留氣泡，薄片不發生皺紋，黏貼後大致可形成平 坦的薄片面。 【用以解決課題之手段】 本發明係一種貼附裝置，係將黏貼面局部具有的凸出 部之大致平坦的薄片，隔著黏著層一面加壓一面貼附於平 坦的基材之面，該凸出部之高度爲該薄片厚度之5至30 %，其中根據JIS K625 3的基準，加壓部之表面硬度係小於 50’且以該厚度爲凸出部高度之1〇〇〜500倍之彈性體層覆 200827161 蓋。本發明除了以上之外，還包含在該基材的黏貼面形成 與外周緣連結之溝槽的貼附裝置，更包含了該基材之黏貼 面的表層爲軟質材料所形成的貼附裝置。又，本發明亦包 . 含加壓部係輥子加壓方式，且與輥子表面的加壓部之薄片 • 的接觸線壓爲2kg/ cm以下的貼附裝置，再者，該彈性體 之層是含有矽橡膠者亦包含在本發明內。 本發明之貼附對象，係「在黏貼面局部具有其厚度之 φ 5至30%之高度的凸出部之大致平坦的薄片」。所謂「局 部」係指相當於黏貼面積之40%以內，所謂「大致平坦」 係指局部亦即40%範圍內之面積具有凸出部，剩餘之面成 爲平坦的狀態。此外，在此具凸出部之區域的面積亦包含 其底部的部分。在本發明意味著「平坦」雖定義如下，但 關於在本發明使用於基材之面等的「平坦」也是同樣意義。 再者，在本發明尤其是表示「薄片」的情況係指厚度小於 0 · 5 mm 者。 # 在本發明所謂的「平坦」，係指黏貼薄片或基材之厚 度方向的凸出部之最大高度△ t是1 0 // m以下的狀態。貼 附前之薄片面的平坦度係使用以下的順序量測。首先準備 切出矩形之長方形薄片。接著使薄片承載於平板上，以平 板面作爲基點，於薄片之兩個對角線方向將薄片之上面與 基點之距離t (實際薄片的厚度），等間隔地確認至少i 〇 點。連續記錄讀取資料亦可。量測手段可以是通常採用之 接觸方式或非接觸方式等之任何方法，但像針盤指示量規 200827161 使其接觸在測量面之接觸方式的情況，要使用接觸部是與 測量面平行地作面接觸的端子。從被記錄的資料來確認t 的算術平均値t〇(作爲基準厚度。單位爲// m)、最大値tmax (單位爲//m)、厚度方向之凸出部的最大高度Δΐ亦即（tmax -U )。此値越小越平坦。此外薄片之測量面爲非矩形時的 測量方向係配合薄片面的形狀，必定使沿著面上最長區間 線之方向涵蓋在一個測量方向。例如，薄片面爲圓形時沿 I 著其直徑互相正交的兩方向，薄片面爲橢圓時分別選擇沿 著其長徑及短徑之兩方向。又貼附後之薄片面的平坦度， 係將貼附在基材之物承載於平板上，使用與上述貼附前之 薄片的情況同樣的順序，確認從平板基點到薄片面的距離 t (薄片、基材及黏著層的合計厚度），從其算術平均値U 與取大値t m a X算出Δΐ；β卩（tmax-to)。另外，此時’黏著層 與基材的厚度相抵，該等各個測量値的變動比薄片的變動 小，對於△ t的影響幾乎可以視爲沒有。 φ 【發明效果】 透過本發明可提供一種貼附裝置，其即使是在把要貼 附之面是大致平坦但局部具有其厚度之5至30%之高度的 凸出部的薄片貼附於平坦的基材之面時，在黏貼的界面不 殘留氣泡，薄片不發生皺紋，黏貼後大致可形成平坦的薄 片面。因此，可提供薄片部分與基材部分密接度優良的貼 附構件。又若使用透明之薄片亦可提供透光性優良的被覆 構件。更因爲也可使用於薄片與基材雙方都平坦的情 200827161 況’故可將貼附對象大大地擴展。 【實施方式】 以下列舉本發明之裝置的構成例加以說明。本發明之 裝置可適用於紙、樹脂、金屬及該等的複合材料或疊層體 等各種薄片材料。薄片大致平坦而在其貼合面的局部具有 其厚度之5至30%的高度之厚度方向的凸出部。該面內凸 出部所佔有之面積的比率，通常爲40%以下，但其厚度方 φ 向的高度若在上述範圍內時，從上面看凸出部的形態，例 如’線狀、帶狀、島狀等各種形態均被容許。此外凸出部 之面積從上看時係包含到其下端的周邊。之所以要將薄片 凸出部之厚度方向的高度取爲薄片厚度之5至30%，乃是 因爲在未滿5 %時，以通常的加壓手段對於整體平坦的薄 片亦可達成上述的效果。又，在超過30%時，在貼附後， 對應於凸出部之薄片的相反側之表面難以變平坦。 在本發明之裝置所處理的薄片黏貼面，可於貼附前事 • 先形成黏著層，未事先形成亦可。黏貼時之黏著層的厚度 雖未受限制，最好是比上述凸出部之厚度方向的高度更高 者較爲理想。據此，可透過黏著層將薄片凸出部之恢復應 力吸收某種程度。當然黏著層的材質或凸出部的形態是有 需要依照實用上的目的而改變。例如，若是在薄片上印刷 電子電路而要暫時固定的情況，例如，使用感壓黏著劑等 之黏著性弱的黏著劑，使事後容易分離。又，例如，若是 永久固定的情況時，使用熱硬化性黏著劑，使之不會剝離。 -10- 200827161 再者，例如，將印刷有電子電路之撓性印刷電路薄片貼附 於基材並施以軟焊構裝的情況時，也有必要考慮熱對策或 焊錫流對策。 在使用本發明裝置之貼附過程，依薄片的材質與凸出 部的形態，基材表面的狀態，有氣泡容易殘留於黏著層的 情況。例如，在小的凸出部局部地集中時、基材表面堅硬 時、使用彈性大的薄片時，在凸出部與其周邊容易殘留氣 泡。在此種情況時，於基材的表面形成溝槽以與外周緣連 結較爲理想。透過此，可在加壓的同時藉由黏著層的流動 而積極地將氣泡趕出。再者，將基材表面作成軟質者較爲 理想。據此，可藉由黏著層而將薄片凸出部的恢復應力圓 滑地吸收，同時不致於發生抱進新氣泡的情形。 在基材之面形成溝槽的手段係有：（1)鈾刻等化學的方 法或雷射照射抑或機械加工等之物理方法直接在基材表面 形成溝槽的方法，（2)將被以期望之溝槽圖案掩蔽之基材表 面以印刷或蒸鍍等方式形成被覆層的方法，以及（3)黏貼附 有溝槽圖案之薄膜片的方法等。面方向之溝槽圖案，只要 是成爲連結於基材面之外周緣者，任何均可。從上看整體 的面內圖案，雖有圍棋盤格子狀者或從中央輻射狀擴展者 等，但從上看盡可能朝外周緣方向能描劃圓滑的連結曲線 時，黏著層的流動成爲順暢而使氣泡容易趕出。例如，在 凸出部局部地集中時，作成從該部分朝向外周圓滑的連結 而成輻射狀延伸之形態者。又，例如，以輥子或橡皮輥子 200827161 向單一方向加壓時，沿著其加壓進行方向附加溝槽。其他 依各種情況可考慮各種圖案。從厚度方向看溝槽的剖面， 雖可考慮爲V字形狀或U字形狀等各種形狀，但開口端的 寬度或深度，較凸出部的高度更大者爲佳。尤其是溝槽的 深度爲凸出部高度的125〜150%的範圍更理想。在未滿下限 時，則隨著反覆的加壓，被加壓之面內的壓力變動大，有 變成難以脫泡的情況。而在超過上限時，則隨著反覆的加 壓，會有因爲貼附後之薄片的恢復而變得容易抱進新氣泡 的情況，或在溝槽的部分薄片容易局部變形的情況。將溝 槽圖案化之被覆層的厚度或附有溝槽之黏著薄膜的厚度也 同樣地作成比凸出部的高度還大者爲宜。 在基材表面上形成如上的溝槽，同時使之持有適度的 柔軟性者爲宜。所期望之表面硬度根據ns K635 3的基準係 未滿70。此外比加壓部分的表面硬度還高者爲宜。雖亦依 據加壓部分的表面材料而定，但例如，有矽樹脂、天然橡 膠、氯丁橡膠等’依照用途亦可在基材使用該等材料。使 用硬度更高的基材時，使薄片貼合面預先形成含軟質材料 的成分之層。在其手段方面，亦有（4)透過印刷或蒸鍍方式 於基材面形成新軟質材料層的方法，（5)將軟質材料之薄膜 貼著於基材面的方法等。更有（6)使軟質材料之層成爲基材 與軟質材料之傾斜機能的複合層的方法。在此種情況下， 朝向表面使軟質材料的成分量增多。透過此，因爲表面與 基材的界面被連續化使雙方的接合可靠性提高，所以例 -12- 200827161 如，適合於黏貼後的加工或於實際運用時伴隨有冷熱負載 之情況。此外，在同時執行軟質材料層與溝槽的形成時， 形成上述溝槽的手段（1)〜（3)，與形成該等軟質材料層的手 段（4)〜（6)亦可相互前後進行。例如，（4)與上述之溝槽形成 手段（2)、（5)及上述之溝槽形成手段（3)，因爲分別伴隨著相 互共同的操作，所以亦可相互同時或前後進行。 在本發明的裝置，係於貼附時施加壓力。在那時之加 壓部分的表面係以根據】IS K625 3之表面硬度未滿50的彈 性體被覆，而使其厚度爲薄片之凸出部高度的100〜500倍。 加壓部分的表面硬度設爲IIS K625 3基準下未滿50的理 由，係若超過的話，於薄片凸出部界面附近會殘留氣泡， 或黏貼後由於薄片的恢復而發生皺摺，使薄片無法密接而 容易上浮或抱進氣泡之故。又彈性體的厚度作成上述範 圍，係依照黏貼時凸出部的形態，在未拘束其周邊想繞進 之黏著層的動向之下，將集中於薄片凸出部之應力吸收緩 Φ 和而分散到薄片平坦部之故。此外也依黏著層或薄片之材 質而定，此表面硬度希望是20以上。又加壓部分的表面， 依薄片凸出部的形態，沿著平面、曲面、凸出部之凹陷狀 的凹陷或貫通孔等，可成爲三維的各種外圈形狀。彈性體 通常雖使用橡膠，但依照情況，例如，亦可內裝有彈簧者。 更，若彈性體的表面容易黏著於薄片者，將其按住於薄片 時容易妨礙黏貼。因此，選擇表面難以黏貼在薄片的彈性 體爲宜。若作以上考慮時，則以含有矽橡膠系或氟橡膠系 -13- 200827161 之材料爲理想。但即使彈性體本身具有黏著性，透過在其 表面載上非黏著性之層亦可使用。例如，亦有在天然橡膠 或氨基甲酸乙酯橡膠之上被覆聚四氟化乙烯（PTFE)者。 加壓手段，只要是能滿足上述條件者即可。在薄片連 續地被運送供應移動的情況，例如，有以輥子加壓方式或 以多段的沖壓而階段性加壓者等。又例如，將長方形之薄 片個別地加壓時，此等之外再加上以橡皮輥子加壓的方式 φ 或以單一沖壓施加規定時間的面壓之方式等。以輥子或橡 皮輥子等沿著面施加壓力時，其接觸線壓以2kg/ cm以下 爲宜。其原因在於，若超過此接觸線壓，於黏貼時會拘束 在凸出部附近變形想繞進之黏著層的動向，阻礙氣泡脫 出，賦予薄片過度伸長，而容易因事後的恢復造成剝離或 皺摺的原因。此外該接觸線壓係因薄片的材質或厚度、基 材表面的形態等而改變，但爲了抑制氣泡的殘留與黏貼後 薄片的恢復，大槪是以0.05kg/ cm以上爲宜。又，理想的 4^ 上限爲1 · 5 k g / c m以下。此外在此作爲「接觸線壓」，乃 因輥子或橡皮輥子等與薄片的接觸爲線狀之故。因此，若 接觸線的長度爲L(cm)，則接觸線壓之値，爲負載之載重（kg) 除以長度L之後的値。此外根據薄片的材質或其凸出部的 形態、黏著層的材質，在加壓的同時會有再加熱或照射光 等的情況。 作爲在本發明裝置處理之薄片的凸出部之例，會有在 黏貼後的折彎，割斷，爲了零件裝設而形成貫通孔或窪陷 -14- 200827161 時產生在相反側之面的周邊緣的突出（毛邊寺）寺。然而 同時在此具有凸出部的面上欲印刷電子電路等的圖案以 成機能部的情況，該面爲平坦者爲宜。此種情況下’若 用本發明之裝置，即使是如上述具有凸出部的薄片’若 厚度方向的高度爲30%以下時，容易獲得所欲之平坦的 準。以下，雖透過實施例說明本發明。但，本發明並不 定於此。 0 實施例1 準備紙、聚對苯二甲酸乙二醇酯（以下簡稱PET ) 純銘（A1)而成之寬度80mm而厚度爲200// m的長條薄片

Description of the Invention: [Technical Field of the Invention] The present invention relates to an attachment device for attaching a substantially flat excellent adhesion of a projection portion to a flat substrate. [Prior Art] A method of attaching a sheet to the surface of a substrate via an adhesive layer has been gradually developed in view of the practical function or form of the product. For example, Japanese Patent Publication No. Hei 7-272625 (Patent Document 1) discloses a glass bulb which is conveyed by a flat PET sheet (polyethylene terephthalate) on a surface having fine irregularities. The resin suppresses the generation of wrinkles, foreign matter, and wrinkles of the sheet, and the like, in which the rubber placed on the roller absorbs the unevenness or curvature of the surface to which the bulb is attached. Accordingly, it is suggested that if the hardness of the roll rubber is too high, bubbles or grooves will be caught at the end portions in the width direction, and not only the adhesion strength but also the transparency after the coating cannot be ensured, and the side of the tube having a width of 250 mm is introduced. The polyurethane sheet with a thickness of 20/zm is placed at a speed of 40//, and the rubber with a surface hardness of 50 or less and a thickness of 10 mm is added with 55 kg or more (the contact line pressure in the width direction is 2.2 kg/cm). A method of attaching a load. Japanese Patent Laid-Open No. Hei 6-5572 No. 1 (Patent Document discloses that a photo of a resin impregnated with natural stone powder is placed on an artificial marble, and a transparent resin layer is coated thereon. A method of manufacturing an artificial stone ornament for mounting a sheet. In order to pass through a sheet of a transparent resin layer, it is used in Japan, and a sheet of a rubber roller is used. The rubber of the sheet is wrinkled. As a stick of 1 800 mm m, the above applies) The layer is loaded with a portrait that can clearly see the photo in 200827161. It is necessary to leave no bubbles on the resin layer. Therefore, when the resin layer is hardened, the resin is applied. The photo-loaded workpiece is placed on the printing table, and the frame with the flexible sheet is pushed against the coated surface, and the bubble is released by printing on the pressure roller. At that time, - The peripheral end portion of the frame is evacuated from the outside through the suction hole of the printing table. Therefore, the resin layer of the sheet on the workpiece is in a structure that adheres to the resin layer and promotes bubble escape from the resin layer. In addition, Japanese Patent Laid-Open Publication No. 2005-135350 No. 3 (Patent Document 3) describes the case where a fiber-reinforced plastic (FRP) sheet is interposed with an ultraviolet-curable adhesive layer on a concrete wall in a tunnel. The means for removing the air bubbles remaining at the bonding interface. For example, it is disclosed that the release sheet is attached to the sheet in advance, and the adhesive layer is cured by pressurizing the bubble from above, and the peeling sheet is peeled off. [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. [Problems to be Solved by the Invention] As in the above example, when attaching a sheet to protect the product, it is necessary to improve the adhesion of the sheet to the substrate (the performance of the bonding interface of both sides without contact and contact). The same applies to the case where the sheet is attached to the substrate surface, and the functional portion such as an electronic circuit or a printed display having a predetermined thickness is formed thereon. In any case, no air bubbles remain at the interface between the substrate and the sheet, 200827161 Furthermore, since the expansion and contraction at the time of attachment is restored afterwards, it is important that the sheet does not float from the substrate. Moreover, the adhesion is good, for example, the surface is undulated, adsorbed moisture or dirt, etc. The surface morphology of the material and the sheet is affected, which has a great influence on the practical function of the attached product or its sustainability. Conventionally, in order to remove bubbles or to avoid recovery after stretching of the sheet, the recommended means is as described in the above patent document, which is uniform pressurization by a roller. However, most of them are examples of attaching to a flat sheet. For example, Patent Document 1 suggests a means for flexibly changing the rubber hardness or thickness of a roller that conforms to the undulation of the surface of the sheet. However, this means has a partial undulation on the sheet, and it is difficult to make the surface of the attached sheet substantially flat. The means of Patent Documents 2 and 3 are also the case where the sheet has no undulation, and it can be said that it is the same as Patent Document 1. An object of the present invention is to provide an attaching device which can be attached to a flat substrate surface even in a sheet having a projection portion which is substantially flat but has a height of 5 to 30% of its thickness. At the time of adhesion, no bubbles remain at the interface of the adhesion, and the sheet does not wrinkle, and a flat sheet surface can be formed substantially after the adhesion. [Means for Solving the Problem] The present invention relates to an attachment device which is a substantially flat sheet having a convex portion partially provided on an adhesive surface, which is attached to a flat substrate surface while being pressed against the adhesive layer. The height of the protrusion is 5 to 30% of the thickness of the sheet, wherein the surface hardness of the pressing portion is less than 50' and the thickness is 1 to 500 times the height of the protrusion according to JIS K625 3 The elastomer layer is covered by the 200827161 cover. In addition to the above, the present invention further includes an attachment device for forming a groove that is joined to the outer peripheral edge of the adhesive surface of the substrate, and further includes an attachment device formed of a soft material on the surface of the adhesive surface of the substrate. Further, the present invention also includes an attachment device including a pressurizing portion roller press method and a contact line pressure of a sheet of the pressurizing portion on the surface of the roller of 2 kg/cm or less, and further, the layer of the elastic body Those containing yttrium rubber are also included in the present invention. The object to be attached according to the present invention is a "substantially flat sheet having a convex portion having a thickness of φ 5 to 30% on the adhesive surface." The term "partial" means that it is within 40% of the area of the adhesive. The term "substantially flat" means that the area within 40% of the area has a convex portion, and the remaining surface is flat. Further, the area of the region having the projections also includes the portion at the bottom thereof. In the present invention, the term "flat" is defined as follows. However, the term "flat" used in the surface of the substrate or the like of the present invention is also the same. Further, in the present invention, particularly, the case of "sheet" means a thickness of less than 0 · 5 mm. In the present invention, "flat" means a state in which the maximum height Δt of the convex portion in the thickness direction of the adhesive sheet or the substrate is 1 0 // m or less. The flatness of the sheet surface before attachment is measured using the following sequence. First prepare to cut out a rectangular rectangular sheet. Next, the sheet is placed on the flat plate, and the flat surface is used as a base point, and the distance t between the upper surface of the sheet and the base point (the thickness of the actual sheet) is confirmed in the diagonal direction of the sheet, and at least i 〇 is confirmed at equal intervals. Continuous recording and reading of data is also possible. The measuring means may be any method such as a contact method or a non-contact method which is usually employed, but in the case where the dial indicating gauge 200827161 is brought into contact with the measuring surface, the contact portion is used in parallel with the measuring surface. Surface contact terminals. From the recorded data, the arithmetic mean 値t 〇 of t (as the reference thickness. The unit is // m), the maximum 値tmax (unit: / / m), and the maximum height Δ of the bulge in the thickness direction are also known ( Tmax -U ). The smaller the 値, the flatter it is. In addition, when the measuring surface of the sheet is non-rectangular, the measuring direction is matched with the shape of the sheet surface, and the direction along the longest section line along the surface must be covered in one measuring direction. For example, when the sheet faces are circular, they are oriented in two directions orthogonal to each other in diameter, and when the sheet faces are elliptical, they are selected in both directions of the major axis and the minor axis. Further, the flatness of the sheet surface to be attached is carried on the flat plate by the object attached to the substrate, and the distance t from the base point of the flat sheet to the sheet surface is confirmed in the same order as in the case of the sheet before the attaching ( The total thickness of the sheet, the substrate, and the adhesive layer is calculated from the arithmetic mean 値U and the 値tma X to calculate Δΐ; β卩(tmax-to). Further, at this time, the thickness of the adhesive layer and the thickness of the substrate are offset, and the fluctuation of each of the measurement ridges is smaller than the variation of the sheet, and the influence on Δt can be regarded as almost no. φ [Effect of the Invention] According to the present invention, it is possible to provide an attaching device which is attached to a flat sheet even if the surface to be attached is substantially flat but partially has a height of 5 to 30% of its thickness. When the surface of the substrate is placed, no bubbles remain at the interface of the adhesion, and the sheet does not wrinkle, and a flat sheet surface can be formed substantially after the adhesion. Therefore, it is possible to provide an attaching member excellent in adhesion between the sheet portion and the base portion. Further, if a transparent sheet is used, a coated member excellent in light transmittance can be provided. Further, since it can be used for both the sheet and the substrate to be flat, the attachment object can be greatly expanded. [Embodiment] Hereinafter, a configuration example of the apparatus of the present invention will be described. The apparatus of the present invention is applicable to various sheet materials such as paper, resin, metal, and composite materials or laminates thereof. The sheet is substantially flat and has a projection in the thickness direction of a height of 5 to 30% of its thickness at a portion of the bonding surface. The ratio of the area occupied by the in-plane projection is usually 40% or less. However, when the height in the thickness direction φ is within the above range, the shape of the projection is seen from the top, for example, 'linear shape, strip shape Various forms such as islands are allowed. Further, the area of the projection is included from the top to the periphery of the lower end thereof. The reason why the height in the thickness direction of the sheet projecting portion is 5 to 30% of the thickness of the sheet is because the above-mentioned effect can be achieved for the generally flat sheet by a normal pressurizing means when the thickness is less than 5%. . Moreover, when it is more than 30%, it is difficult to flatten the surface of the opposite side of the sheet corresponding to the convex part after attachment. In the adhesive surface of the sheet processed by the apparatus of the present invention, the adhesive layer can be formed before the attachment, and the adhesive layer can be formed without prior formation. The thickness of the adhesive layer when pasted is preferably not limited, and is preferably higher than the height of the convex portion in the thickness direction. According to this, the recovery stress of the sheet convex portion can be absorbed to some extent through the adhesive layer. Of course, the material of the adhesive layer or the shape of the projections needs to be changed in accordance with practical purposes. For example, in the case where the electronic circuit is printed on the sheet and temporarily fixed, for example, an adhesive having a weak adhesiveness such as a pressure-sensitive adhesive is used to facilitate separation afterwards. Further, for example, in the case of permanent fixation, a thermosetting adhesive is used so as not to peel off. -10- 200827161 In addition, when a flexible printed circuit sheet on which an electronic circuit is printed is attached to a substrate and applied to a solder joint, it is necessary to take measures against heat or solder flow. In the attaching process using the apparatus of the present invention, depending on the material of the sheet and the form of the projection, and the state of the surface of the substrate, bubbles may easily remain in the adhesive layer. For example, when the small projections are partially concentrated and the surface of the substrate is hard, when a sheet having a large elasticity is used, air bubbles are likely to remain in the projections and the periphery thereof. In this case, it is preferable to form a groove on the surface of the substrate to be bonded to the outer periphery. Through this, the bubble can be actively driven out by the flow of the adhesive layer while being pressurized. Further, it is preferred to make the surface of the substrate soft. According to this, the recovery stress of the sheet projecting portion can be smoothly absorbed by the adhesive layer without causing a situation in which new air bubbles are caught. The means for forming the groove on the surface of the substrate are: (1) a chemical method such as uranium engraving or a physical method such as laser irradiation or machining, which directly forms a groove on the surface of the substrate, and (2) A method of forming a coating layer by printing or vapor deposition on a surface of a substrate to be masked by a desired groove pattern, and (3) a method of adhering a film sheet having a groove pattern. The groove pattern in the surface direction may be any one that is connected to the periphery of the substrate surface. From the top, the overall in-plane pattern, although there is a checkerboard grid shape or a radial spreader from the center, but when the smooth connection curve can be drawn as far as possible from the top, the flow of the adhesive layer becomes smooth. And make the bubbles easy to drive out. For example, when the projections are partially concentrated, a shape that is smoothly connected from the portion toward the outer circumference is formed to be radially extended. Further, for example, when the roller or the rubber roller 200827161 is pressed in a single direction, a groove is added in the direction in which the pressure is applied. Others Various patterns can be considered depending on the circumstances. The cross section of the groove as viewed in the thickness direction may be various shapes such as a V shape or a U shape, but the width or depth of the open end is preferably larger than the height of the convex portion. In particular, the depth of the groove is preferably in the range of 125 to 150% of the height of the projection. When the lower limit is not reached, the pressure in the surface to be pressurized is greatly changed with the repeated pressurization, and it may become difficult to defoam. On the other hand, when the upper limit is exceeded, the pressure may increase, and the new sheet may be easily caught by the recovery of the attached sheet, or the sheet may be partially deformed locally in the groove. The thickness of the coating layer patterned by the groove or the thickness of the adhesive film with the groove is also preferably made larger than the height of the protruding portion. It is preferred to form the above grooves on the surface of the substrate while maintaining moderate flexibility. The desired surface hardness is less than 70 based on the basis of ns K635 3 . Further, it is preferable that the surface hardness of the pressurized portion is higher. Depending on the surface material of the pressurizing portion, for example, enamel resin, natural rubber, chloroprene rubber, etc. may be used in the substrate depending on the application. When a substrate having a higher hardness is used, a layer of a component containing a soft material is formed in advance on the sheet bonding surface. Further, there are (4) a method of forming a new soft material layer on the substrate surface by printing or vapor deposition, and (5) a method of adhering a film of a soft material to the substrate surface. Further, (6) a method of forming a layer of a soft material into a composite layer of a tilting function of a substrate and a soft material. In this case, the amount of the component of the soft material is increased toward the surface. As a result, since the interface between the surface and the substrate is continuous and the joint reliability is improved, the example -12-200827161 is suitable for the post-adhesive processing or the case where the hot and cold load is applied in actual use. Further, when the formation of the soft material layer and the groove is simultaneously performed, the means (1) to (3) for forming the groove and the means (4) to (6) for forming the soft material layer may be performed one after another. . For example, (4) and the above-described groove forming means (2), (5) and the above-described groove forming means (3) are mutually simultaneously or front-rear, because they are operated in common with each other. In the device of the present invention, pressure is applied at the time of attachment. The surface of the pressed portion at that time was covered with an elastic body having a surface hardness of less than 50 according to IS K625 3, and the thickness thereof was 100 to 500 times the height of the convex portion of the sheet. The surface hardness of the pressurizing portion is set to be less than 50 under the IIS K625 3 standard. If it exceeds, bubbles may remain in the vicinity of the interface of the sheet protruding portion, or wrinkles may occur due to recovery of the sheet after the bonding, and the sheet may not be formed. Closely connected and easy to float or hold into the bubble. Further, the thickness of the elastic body is set to the above range, and in accordance with the form of the convex portion at the time of pasting, the stress absorbing Φ concentrated and concentrated in the convex portion of the sheet is dispersed under the movement of the adhesive layer which is intended to be wound around the periphery thereof. To the flat portion of the sheet. Further, depending on the material of the adhesive layer or the sheet, the surface hardness is desirably 20 or more. Further, the surface of the pressurizing portion can be formed into various three-dimensional outer ring shapes along the plane, the curved surface, and the concave recesses or through holes of the projections in the form of the sheet projecting portion. Elastomers Although rubber is usually used, depending on the circumstances, for example, a spring may be incorporated. Further, if the surface of the elastic body is likely to adhere to the sheet, it is likely to hinder the sticking when it is held down on the sheet. Therefore, it is preferable to select an elastic body whose surface is difficult to adhere to the sheet. When considering the above considerations, it is preferable to use a material containing ruthenium rubber or fluororubber -13-200827161. However, even if the elastomer itself has adhesiveness, it can be used by carrying a non-adhesive layer on its surface. For example, there are also those coated with polytetrafluoroethylene (PTFE) on top of natural rubber or urethane rubber. The pressurizing means may be any one that satisfies the above conditions. In the case where the sheet is continuously conveyed and supplied, for example, there is a step of pressurizing by a roll press method or a plurality of stages of pressurization. Further, for example, when the rectangular thin sheets are individually pressed, the φ or the surface pressure of a predetermined time by a single press is added in addition to the φ by the squeezing of the squeegee. When a pressure is applied along the surface by a roller or a rubber roller or the like, the contact line pressure is preferably 2 kg/cm or less. The reason for this is that if the contact line pressure is exceeded, the movement of the adhesive layer that is intended to wrap around is deformed in the vicinity of the protruding portion during the pasting, and the bubble is prevented from coming off, and the sheet is excessively stretched, which is liable to cause peeling due to recovery after the event or The reason for the wrinkles. Further, the contact line pressure is changed depending on the material or thickness of the sheet, the shape of the surface of the substrate, etc., but it is preferably 0.05 kg/cm or more in order to suppress the residual of the bubbles and the recovery of the sheet after the adhesion. Also, the ideal 4^ upper limit is 1 · 5 k g / c m or less. Further, it is referred to herein as "contact line pressure" because the contact of the roller or the rubber roller with the sheet is linear. Therefore, if the length of the contact line is L (cm), the contact line pressure is the load (kg) divided by the length L. Further, depending on the material of the sheet, the form of the projections, and the material of the adhesive layer, it may be heated or irradiated with light or the like while being pressurized. As an example of the projection of the sheet processed by the apparatus of the present invention, there is a bend after the pasting, and the cut is made, and a through hole or a depression is formed for the part mounting, and the circumference on the opposite side is generated when the flaw is formed. The edge of the prominent (Maobian Temple) Temple. However, in the case where the surface having the projections is to be printed on the surface of the projection portion to form a functional portion, it is preferable that the surface is flat. In the case of the apparatus of the present invention, even if the height of the sheet ′ having the projections as described above is 30% or less in the thickness direction, it is easy to obtain a desired flatness. Hereinafter, the present invention will be described by way of examples. However, the present invention is not limited to this. 0 Example 1 Preparation of paper, polyethylene terephthalate (hereinafter referred to as PET) Pure ingot (A1), a strip of material having a width of 80 mm and a thickness of 200 / / m. These raw material sheets were fed from a roll to a molding machine, and the surface was processed and cut into a rectangular shape having a length of 60 mm. Through this preparatory work, a test piece having a plurality of types of sheets having the form and height of the type described in the column of the first table is obtained on one of the sheets. In addition, the burrs of the cut ends are present in The surface having the side of the projections is provided, but the height is also about 3/m. The flatness of the sheets is confirmed by a thin sheet having a length of 160 mm and the diagonal direction is confirmed. The maximum height At in the thickness direction is 10/zm or less. Using these test pieces and the conditions of 35 kinds shown in Table 1, each piece 'sees 10 in in, length 155 in, thickness 2 mm 'on the flat base made of glass fiber reinforced epoxy resin with fluororubber layer on the surface, the surface with the convex portion is pressed against the adhesive layer and adhered to the substrate surface. However, there is a concavity in which At is ΙΟ/zm or less. The shape is such that the water limit and the original pre-addition j are 5, and the square 20 is made of -15-200827161, and when attached, as shown in Fig. 2, The sheet 1 can be accommodated in the center of the width direction of the adhesive layer 2, and is oriented in the length direction of the sheet The end is attached to the front of the eye (in the direction of the arrow in Fig. 2) by 5 mm. The broken line portion 11 is a convex portion of the sheet. Fig. 1 is a schematic view showing the attachment state of the roller method used in the present embodiment. In the figure, 1 is a sheet, 2 is an adhesive portion, 3 is a base material, 4 is a pressure roller, 5 is an elastic layer covering the roller, and 6 is a roller of a cylinder or the like. Further, in the figure For example, the vicinity of the convex portion of the sheet is a cross section shown on the right side of the sheet, and there is a convex portion (burr or the like) under the sheet. The form of the convex portion of the sheet to be used is as shown in the category column of the first table. There are five types of "line", "multi-point", "dot", "band" and "depression", which are shown in Figures 3A to E. In the figure, the above view is in the right circular frame, which is an enlarged view of the vicinity of the projection. The blackened part of the frame is a through hole. As shown in Fig. 3A, the through-holes which are island-shaped in the longitudinal direction in the central portion in the width direction of the sheet are arranged side by side on a straight line. The through hole has a width of about 0.5 mm and a length of about 1 mm, and the end of the opening has a distance of 1 mm from the end. At the peripheral edge portion of the through hole, there is a projection having a width of 0.1 mm at the lower end of the tapered portion, and the height in the thickness direction is 8 to 70 // m as shown in Table 1. As shown in Fig. 3B, a circular through-hole having a diameter of 55 mm is placed at the same position as the linear one, and a gap of 0.5 mm is left at the end of the opening. At the peripheral edge portion of the through hole, there is a projection having a lower end of 0.1 mm in width, and the height in the thickness direction is 20 #m. As shown in Fig. 3C, in the same position as the linear one, in the range of -16 - 200827161, the end of the width is 5 mm apart from the end, and the two islands of the same shape are the same as the linear one. The through hole extends linearly. At the peripheral edge portion of the through hole, there is a projection having the same size as that of the linear shape, and the height in the thickness direction is 20 / / m. As shown in Fig. 3D, as shown in Fig. 3D, a circular depression having the same outer edge shape and spacing as that of the dot shape is formed at a depth of about 30/m. At the peripheral edge portion of the recess, there was a projection having a width of 0.1 mm which was pulled at the lower end of the tapered shape, and the height in the thickness direction was 20 / m. In addition, as shown in FIG. 3E, in the same manner as in the 3D drawing, the depressions of the projections having the same height in the same thickness direction at the peripheral edge portion are arranged in the vertical and horizontal directions as a checkerboard. The grid forms a majority. In this case, the proportion of the projections included in the lower end portion on the sheet surface is about 40%.

The test material number in the table is preceded by a * mark, which is a test material of the comparative example of the present invention. The "paper", "PET" and "A1" in the material column of the sheet are as described above. The height of the projections is the ratio of the maximum 値 and thickness of each of the protrusion heights in the thickness direction of the projections to the thickness (average 値) of the sheet. The type of the projection is as described above. A in the "Material" column of the adhesive layer is "Kneading Rubber" manufactured by Nippon Electric Chemical Co., Ltd., and "High Density" of ThreeBond2082C Normal Temperature Hardening Two-component Epoxy Resin, manufactured by B-Series Three Bond φ Co., Ltd. Adhesive type of bonding agent. The "thickness" of the adhesive layer is the estimated thickness after pressurization, and is calculated by subtracting the thickness from the total thickness of the sheet and the substrate. "R0L", "SQZ", and "PRS" in the "Method" column of the pressure-attachment method are used to sequentially apply a contact line pressure from one side to the side of the sheet by pressing the roller. The contact line pressure is applied to suppress the sheet from being pressed by the squeegee while being pressed, and the stamping method in which the surface pressure is gradually applied by the cam-type pressing method. The "SIR" in the material column shows the rubber-based material, and the contact surface of the sheet with the pressurizing portion is made of a rubber-based material. As indicated in the table, the Hs hardness of the surface is adjusted to 10 to 55, and the rubber-based material is used. The number of thickness magnifications of the pressurizing portion is the thickness of the elastic portion of the pressurizing portion of each test material except the height (%) of the height of the convex portion of the sheet. Taking the load column as an example, "line 1 · 5" shows that the contact line pressure with the sheet applied by the roller or the rubber roller is 1 · 5 k g / c m. In the present embodiment, since the roller -19-200827161 or the rubber roller is pressed in the width direction of the entire sheet to be moved in the longitudinal direction, the total load of the load is divided by 8 cm. For another example, "face 0.2" shows a press pressure of 0.2 kg/cm2. In this case, the load of the load is reduced by a volume of 124 cm2 (15.5 cm x 8 cm). 20 test pieces of each test in the form of adhesion shown in the above-mentioned Fig. 2, and the adhesion of the sheet surface after the adhesion of 10 test pieces was confirmed in the state under the respective pressure conditions. Using a 100-fold optical microscope (there are two corners in the diagonal direction of the sheet and three bubbles in the center, and the results are shown in the column of "Tan" and "Bubble" in Table 1. In addition, there is a column of "thinness". In addition, the "thinness" column confirms the ratio from the level of the original sheet surface to the change of the adhesion, and the size of the ◎ 〇 △ X is expressed as less than 1%. 1% or more and less than 3% • Full 5% or more, and 5% or more. Regarding the presence or absence of air bubbles, it is expressed in (j level) in the total area of the above-mentioned field of view. ◎ is not confirmed. In the case where the ◦ system was confirmed to be at the convex number, the Δ system was confirmed to be around the bulging portion and the number of points was different, and the X system was confirmed to be around the bulging portion and not more than 1 〇. Although not shown in the table, the remaining 10 test pieces will have the width of the substrate. After the two ends of the pair are clamped and fixed, the contact surface material number of the sheet which is peeled toward the sheet of 80 mm is applied to the substrate. The same test material is the field of view. The flat sheet surface of the sheet surface is observed. The water after flattening. Quasi-. 〇 〇 and X, 3% or more are not §) 〇 △ X The order of the bubble is outside the part of the exit, and the other part is separated by the Uig. test. Peeling -20- 200827161 From the test, in Fig. 2, the end of the sheet protruding from the end of the substrate is integrally held in the arm of the soft rubber in the width direction, and the sheet is pulled vertically at a speed of 10 mm/min by a tensile tester. A method of confirming the load on which the sheet is peeled off from the substrate. As a result, the test material of the present invention was 2 kg or more, and the test material of the comparative example was at a level of less than 80%. Further, various soft materials or laminated composite materials which are commensurate with the hardness of the present invention, such as natural rubber or chloroprene rubber other than ruthenium rubber, are adhered to the surface of the pressurizing portion, and are the same as the test material 丨3 Under the conditions of the sheet material, the projections, and the pressurization, the attachment test of the sepals was carried out using the apparatus of the present invention. The level of flatness, presence or absence of residual air bubbles, and peel strength of the test materials were almost the same as those of the test materials 1 to 3. However, materials other than enamel rubber are slightly adhered to or slightly roughened with the PET material sheet as the number of sheets overlaps. Further, 'there is no description in the table, and 20 sheets each of which is formed of the same paper, aluminum, PET, etc. as the test materials 1 to 3 of the first table are additionally prepared. • The width is 100 mm and the length is 155 mm. SUS304 and alumina ceramics having the same size as above, having a thickness of 2 mm and having a fluororubber layer having irregularities of ΔΗΟ/ζιπ or less (from Mg〇2% by mass, Si〇23% by mass, and the remaining part ai2〇) On the flat substrate of the sintered body formed by the chemical composition of 3, the surface having the projections is attached to the same surface as the test materials 1 to 35 of the first table, while being pressed against the adhesive layer. to evaluate. As a result, it was approximately the same level as the test materials 1 to 35. From the above results, the following matters are known. (1) When the surface of the pressurizing portion is hard-21-200827161 degrees Hs is less than 50, and if the height of the protruding portion is 30% or less of the thickness, the undulation of the protruding portion can be absorbed and adhered. As a result, the flatness of the sheet surface on the opposite side and the opposite side can be maintained at an initial level substantially, and practically, it can be adhered without problems. (2) When the projecting portion protrudes from the periphery of the through hole and/or the recess, of course, if it is within 40% of the sheet surface, it can be achieved without problems. (3) When attaching to the roll pressurizing method, when the contact line pressure with the sheet is 2 kg/cm or less, the above flatness and peeling strength φ are preferable, and (4) is applied as additional pressure. The elastomer of the part is easy to use, and the appropriate thickness is between 100 and 500 times the height of the protrusion of the sheet. Example 2 A substrate having various surface forms of the same shape as in Example 1 and a paper having the same convex portion as that of the test material 4 of Example 1 (form of Figure 3E), pure aluminum and PET were prepared. Thin slices. Concavities and convexities of ΔΐΙΟ/ζιπ or less are formed on the surface of the base material. The base material and the sheet were combined with the 23rd group of the second table, and the same as the test material 4 of the first embodiment, the roller pressing conditions were continuously adhered to 5,000 sheets, and the test materials of Example 1 were roughly carried out. 4 same assessment. Specifically, as shown in the column of "Attachment" in Table 2, the flatness of the sheet surface and the residual air bubbles were confirmed in the same manner as in Example 1. Further, the number of test pieces of the bubbles remaining in the sheet after the adhesion of 5,000 sheets was still the number of test pieces of the above-mentioned class of ◎ 〇 Δ and χ. The test piece with the description of the bubble remaining was confirmed to be all the test piece after the 400th chip from the start of the pasting. -22- 200827161 The following explains the contents of the table along the horizontal axis. The column of the test material is indicated in the left column. In the column of the main material, the material of the main material of the substrate is indicated as "GREP", "F rubber" and "alumina", and the same glass fiber reinforced epoxy resin as in Example 1 is sequentially applied and implemented. For example, the same fluororubber as the surface layer of the substrate and the same oxidized ruthenium ceramic as in Example 1. The barrier of the surface layer indicates the material forming the entire layer of the surface of the body material to be the object to be adhered. The "F rubber", "S CN", and "natural rubber" which are displayed in this column are, in order, the same fluororubber, ruthenium rubber resin and natural rubber as the surface layer of the substrate of Example 1. Further, the number 値 written in parentheses after "SCN" indicates the surface hardness Hs of nS K625 3 of the enamel resin material controlled according to the ratio of the organic functional group to the lanthanum element, for example, expressed as "SCN (25)" The resin is represented by a resin having a surface hardness of 25. Further, the test material numbers 10, 1 1 and 2 3 are all substrates having no surface layer, and the body material to be represented is used. Further, irregularities of Δt10 / zm or less were formed on the surface layer of all the substrates. Use examples on this surface!

The composite material layer dispersed at 50% by volume can be formed by being formed on the GREP substrate, and the composite material is 50% by volume of the average diameter of the particles of the SCN (50) and 50% by volume of the epoxy resin. The temperature of the softening I of the oxygen resin is obtained by heating and mixing. Test of Test Material No. 17 The sheet of the composite material and the substrate are placed in a mold heated to a temperature above the I point of the epoxy resin to form a groove. At the same time, the width of the wide width groove represented by the thickness of the mass table is carried by the r ij array in the shape of the cross section. When the particle 1 is above the enthalpy, the f is softened: m heat - 25 - 200827161 Available on the surface of the substrate. The "composite 2" laminate of the test material number 18 is different from the epoxy resin of the test material 17 and scN (5 〇). The layers are layered and pressed against the surface of the substrate. From the substrate side, the first layer' is composed of 70% by volume of epoxy resin, 30% by volume of SCN (50), and the second layer is composed of 50% by volume of epoxy resin and 50% by volume of SCN (50). The three layers are composed of 30% by volume of epoxy resin and 70% by volume of SCN (50). After the lamination of the material which is the material of the layers is carried out from the substrate side, the groove is formed in the third layer in the mold, and the whole is hot pressed, similarly to the test φ material number 17. In addition, the thicknesses of the first layer, the second layer and the third layer are respectively taken as 3 0 // m, 3 0 # m, 4 0 # m. The "composite 3" which is indicated as the test material number 丄9 has a thickness of 100 Å, the open porosity of the outermost surface is 30% by volume, and the open porosity of the back surface is 70% by volume, and the pores of the thickness direction are obtained. After the SCN (50) sheet whose temperature is continuously changed is pressed against the substrate of the glass fiber reinforced epoxy resin, the epoxy resin is placed on the upper surface, and is stored in the container and heated by pressure to melt the molten resin. In the pores of the ® SCN (5〇). Further, irregularities of ΔtO/zm or less were formed on any of the adhesive faces of the test piece. It is indicated as the test material number 20 "film", and the plate of SCN (50) with a thickness of 1 〇〇 # m is carried on the substrate surface of the glass fiber reinforced epoxy resin 'in the hot press at SCN (50) The surface of the surface is formed while the groove is contained in the table. In the case of the test material No. 2, a sheet of natural rubber having a thickness of 1 〇〇//m of a groove as shown in the table is formed in advance, and is thermocompression-bonded to a substrate of a glass fiber reinforced epoxy resin. The test material -26-200827161 number 22 is attached to the aluminum substrate surface described above, and in the same order as test material No. 19, SCN (50) thermocompression γ-oxidation in a three-layer structure. A layer in which aluminum particles are evenly dispersed. The first layer of 70% by volume of alumina and SCN (5 0) 30% by volume of uniformly dispersed r-alumina fine particles having an average secondary particle diameter of 1 / m from the substrate side through the epoxy resin 50% by volume of alumina, 50% by volume of SCN (50), 50% by volume of alumina, and 3% by volume of SCN (50) 70% by volume, in the third layer At the same time as the crimp forming, a groove is added to prepare the person. In the case of the test material No. 23, a predetermined groove is formed on the surface on which the composition of the alumina material is formed and formed. Further, irregularities of Δ or less were formed on any of the adhesive faces of the test piece. Although not described in the table, the durability of the cold and heat cycle based on the presence or absence of soft surface processing has been confirmed. A test piece of the test material Nos. 17 to 20 and 22 subjected to soft surface processing by SCN (50), and a test piece No. 14 having a surface layer formed only of SCN (50) but not subjected to soft surface processing Each test material was prepared for 1 tablet. The test pieces were placed in a thermostatic chamber, and applied in an air at 20 ° C for 30 minutes, at 150 ° C for 30 minutes, and over a thousand cycles of cold and heat cycle load. Afterwards, the flatness of the sheet surface was confirmed in the same order as above. Level change with residual bubbles. As a result, in the test pieces of the test material Nos. 17 to 20 and 22 which had been subjected to the soft surface treatment, the flatness did not change at all in 100, and it was confirmed that there was no increase in residual air bubbles. On the other hand, in the test piece No. 14 of the test material No. 1 which was not processed by the soft surface, it was confirmed that there was an increase in the amount of bubbles in the one of the flatness of the test piece No. -27-200827161. From the above results, the following points are known. (1) The presence or absence of the groove and the shape of the bubble and the effect of the bubble separation based on the hardness of the grooved surface were confirmed mainly from the beginning of the attachment of the 400 pieces. The test material No. 1 without grooves is up to 10 test pieces, and the test material numbers 2 and 3 having a groove depth of 20/zm or less are test pieces of up to 5 sheets, and bubbles are confirmed. The groove is a checkerboard grid shape and the test material number 9 with a groove in the direction orthogonal to the pressing direction, and the test material number for cutting the straight groove on the GREP or alumina ceramic substrate on the hard surface In 1 1 and 2 3, bubbles were confirmed on the test pieces of 2 sheets. Therefore, even if there is a soft surface layer and there is no groove on the substrate surface, the bubbles are hard to be detached when the number of attached sheets is increased. Further, even if there is a groove, if the depth is made smaller than the width, the bubble is hard to be separated. Furthermore, the surface hardness of the surface of the adhesive substrate is preferably less than 70. Further, on the harder substrate surface, a straight surface is formed by cutting a straight groove, and a bubble is formed thereon, and a bubble is formed thereon to be easily separated. (2) The soft surface processing of the laminated structure formed of the composite component is performed by the layer having the groove from the substrate side toward the surface, so that the airtight reliability of the joint portion when receiving the cooling and heating cycle load is improved. Can eliminate new bubbles. [Industrial Applicability] The sheet attaching device of the present invention is attached to the adhesive surface of the sheet, and even if a partial projection is sufficient to affect the flatness after the adhesion, the surface on the opposite side of the undulation portion is substantially flat. The form is attached to a flat substrate surface with high adhesion, and an electric circuit can be easily formed thereon. -28 - 200827161 Thick film printing or the like can be easily formed, and the functional portion can be easily formed. Further, at the adhesive interface, defects due to bubbles or wrinkles are hardly generated. Therefore, when a transparent sheet is used, a coated member excellent in light transmittance can be provided. Of course, it can be used for both the sheet and the substrate to be flat, so that the adhering object becomes wide.
