根據本發明的接合構造體的製造方法以及接合構造體，可實現接合強度的提高。
以下，參照圖式對本發明的實施方式進行說明。 （第一實施方式）
首先，參照圖1對本發明的第一實施方式的接合構造體100進行說明。
接合構造體100如圖1所示，是接合有由不同材料所構成的第一構件10及第二構件20者。在第一構件10的表面13形成有具有開口的穿孔部11，且在該穿孔部11的內周面形成有向內側突出的突出部12。此外，在第一構件10的穿孔部11中填充並固化有第二構件20。再者，圖1是將第一構件10及第二構件20的接合界面放大進行示意性表示的圖，實際上設置有多個穿孔部11，但在圖1中僅示出一個。
第一構件10的材料為金屬、熱塑性樹脂、或熱固性樹脂，第二構件20的材料為熱塑性樹脂、或熱固性樹脂。
作為所述金屬的一例，可列舉：鐵系金屬、不鏽鋼系金屬、銅系金屬、鋁系金屬、鎂系金屬、及該些金屬的合金。另外，可為金屬成型體，亦可為鋅壓鑄、鋁壓鑄、粉末冶金等。
作為所述熱塑性樹脂的一例，可列舉：聚氯乙烯（Polyvinyl chloride，PVC）、聚苯乙烯（Polystyrene，PS）、丙烯腈-苯乙烯（Acrylonitrile-styrene，AS）、丙烯腈-丁二烯-苯乙烯（Acrylonitrile-butadiene-styrene，ABS）、聚甲基丙烯酸甲酯（Polymethyl methacrylate，PMMA）、聚乙烯（Polyethylene，PE）、聚丙烯（Polypropylene，PP）、聚碳酸酯（Polycarbonate，PC）、改質聚苯醚（modified-Polyphenyleneether，m-PPE）、聚醯胺6（Polyamide 6，PA6）、聚醯胺66（PA66）、聚縮醛（Polyacetal，POM）、聚對苯二甲酸乙二酯（Polyethylene terephthalate，PET）、聚對苯二甲酸丁二酯（Polybutylene terephthalate，PBT）、聚碸（Polysulfone，PSF）、聚芳酯（Polyarylate，PAR）、聚醚醯亞胺（Polyetherimide，PEI）、聚苯硫醚（Polyphenylenesulfide，PPS）、聚醚碸（Polyether sulfone，PES）、聚醚醚酮（Polyetheretherketone，PEEK）、聚醯胺醯亞胺（Polyamideimide，PAI）、液晶聚合物（Liquid crystal polymer，LCP）、聚偏二氯乙烯（Polyvinylidene chloride，PVDC）、聚四氟乙烯（Polytetrafluoroethylene，PTFE）、聚氯三氟乙烯（Polychlorotrifluoroethylene，PCTFE）、及聚偏二氟乙烯（Polyvinylidene Fluoride，PVDF）。另外，亦可為熱塑性彈性體（Thermoplastic elastomer，TPE），作為TPE的一例，可列舉熱塑性烯烴（Thermoplastic olefin，TPO）（烯烴系）、熱塑性苯乙烯（Thermoplastic styrene，TPS）（苯乙烯系）、熱塑性酯（Thermoplastic polyester elastomer，TPEE）（酯系）、熱塑性胺基甲酸酯（Thermoplastic urethane，TPU）（胺基甲酸酯系）、熱塑性尼龍（Thermoplastic polyamide，TPA）（尼龍系）、及熱塑性氯乙烯（Polyvinyl chloride based thermoplastic，TPVC）（氯乙烯系）。
作為所述熱固性樹脂的一例，可列舉：環氧（Epoxy，EP）樹脂、聚胺基甲酸酯（Polyurethane，PUR）樹脂、脲甲醛（Urea-formaldehyde，UF）樹脂、三聚氰胺甲醛（Melamine formaldehyde，MF）樹脂、酚甲醛（Phenol formaldehyde，PF）樹脂、不飽和聚酯（U nsaturated polyester，UP）樹脂、及矽（Silicone，SI）樹脂。另外，亦可為纖維強化塑膠（Fiber reinforced plastics，FRP）。
再者，亦可在所述的熱塑性樹脂及熱固性樹脂中添加填充劑。作為填充劑的一例，可列舉無機系填充劑（玻璃纖維、無機鹽類等）、金屬系填充劑、有機系填充劑、及碳纖維等。
穿孔部11在俯視下為大致圓形的非貫通孔，在第一構件10的表面13形成有多個。穿孔部11的表面13的開口徑R1較佳為30 μm以上、100 μm以下。其原因在於：若開口徑R1小於30 μm，則存在第二構件20的填充性變差而錨定效應（anchor effect）降低的情形。另一方面，原因在於：若開口徑R1大於100 μm，則存在每單位面積的穿孔部11的個數減少而錨定效應降低的情形。
另外，穿孔部11的間隔（既定的穿孔部11的中心與鄰接於既定的穿孔部11的穿孔部11的中心的距離）較佳為200 μm以下。其原因在於：若穿孔部11的間隔大於200 μm，則存在每單位面積的穿孔部11的個數減少而錨定效應降低的情形。再者，作為穿孔部11的間隔的下限的一例，為穿孔部11重疊而不崩壞的距離。另外，較佳為穿孔部11的間隔相同。其原因在於：若穿孔部11間隔相等，則剪切方向的接合強度變得等向。
此處，第一實施方式的穿孔部11是以在深度方向（Z方向）上開口徑自表面13側朝向底部113變大的擴徑部111與在深度方向上開口徑自表面13側朝向底部113變小的縮徑部112相連的方式而形成。擴徑部111是以曲線狀擴徑的方式而形成，縮徑部112是以曲線狀縮徑的方式而形成。
此外，擴徑部111是配置於表面13側，並且縮徑部112是配置於底部113側。因此，在穿孔部11中，擴徑部111與縮徑部112的邊界部分的開口徑（內徑）R2變得最大，且開口徑R1變得小於開口徑R2。藉此，將突出部12配置於第一構件10的表面13側。該突出部12例如是跨周方向上的全長而形成，且形成為環狀。
該穿孔部11是藉由照射加工用的雷射而形成。作為雷射的種類，就可進行脈衝振盪的觀點而言，可選擇光纖雷射（fiber laser）、釔鋁石榴石（yttrium aluminum garnet，YAG）雷射、釩酸釔（yttrium orthovanadate，YVO4 ）雷射、半導體雷射、二氧化碳雷射、準分子雷射（excimer laser），若考慮雷射的波長，則較佳為光纖雷射、YAG雷射、YAG雷射的二次諧波、YVO4 雷射、半導體雷射。再者，雷射的輸出是考慮雷射的照射直徑、第一構件10的材料的種類、第一構件10的形狀（例如厚度）等而設定。例如，雷射的輸出上限較佳為40 W。其原因在於：若雷射的輸出超過40 W，則能量變大，難以形成具有突出部12的穿孔部11。
另外，穿孔部11是藉由照射一個脈衝由多個次脈衝所構成的雷射而形成。再者，作為射出此種雷射的裝置的一例，可列舉歐姆龍（OMRON）製造的光纖雷射雕刻機（fiber laser marker）MX-Z2000或MX-Z2050。具體而言，若對第一構件10照射雷射，則藉由將第一構件10局部熔融而進行穿孔部11的形成。此時，由於雷射由多個次脈衝所構成，因此經熔融的第一構件10不易飛散，而容易堆積於穿孔部11的附近。並且，若進行穿孔部11的形成，則藉由將經熔融的第一構件10堆積於穿孔部11的內部而形成突出部12。因此，藉由突出部12將雷射的反射波封閉於穿孔部11的內部，從而利用雷射的加工進一步向深度方向進行。即，變得容易使雷射的能量集中於深度方向。其結果，在穿孔部11中，相對於表面的開口徑R1而深度變大。再者，雷射的照射方向例如是垂直於表面13的方向，穿孔部11的軸心相對於表面13而垂直。
如上所述，藉由照射一個脈衝由多個次脈衝所構成的雷射，而可相對於表面的開口徑R1而加大穿孔部11的深度，因此錨定效應變大，可實現接合強度的提高。進而，在熱循環環境下，即便產生由第一構件10及第二構件20的線膨脹係數差引起的剝離應力，亦可維持接合強度。即，可實現在熱循環環境下的耐久性的提高。
再者，作為利用所述光纖雷射雕刻機的加工條件，較佳為次脈衝的一個週期為15 ns以下。其原因在於：若次脈衝的一個週期超過15 ns，則因導熱導致能量變得容易擴散，而變得難以形成具有突出部12的穿孔部11。再者，次脈衝的一個週期是照射一次次脈衝的時間與該次脈衝的照射結束起至開始下一次次脈衝的照射為止的間隔的合計時間。
另外，作為利用所述光纖雷射雕刻機的加工條件，較佳為一個脈衝的次脈衝數為2個以上且為50個以下。其原因在於：若次脈衝數超過50個，則次脈衝每單位的輸出變小，而變得難以形成具有突出部12的穿孔部11。
此外，第二構件20是接合於形成有穿孔部11的第一構件10的表面13。該第二構件20例如藉由射出成形、熱板熔著、雷射熔著、澆鑄硬化、超音波熔著、或振動熔著而接合於第一構件10。藉此，在將第二構件20填充於穿孔部11中的狀態下進行固化。
此種接合構造體100例如可應用於將樹脂外殼（省略圖示）接合於光電感應器的金屬件（省略圖示）的情形。於該情形時，金屬件相當於第一構件10，樹脂外殼相當於第二構件20。 -接合構造體的製造方法-
繼而，參照圖1及圖2，對第一實施方式的接合構造體100的製造方法進行說明。
首先，如圖2所示，藉由對第一構件10的表面13照射一個脈衝由多個次脈衝所構成的雷射，而在第一構件10的表面13形成穿孔部11，並且在該穿孔部11的內周面形成突出部12。此時，若形成突出部12，則將雷射的反射波封閉於穿孔部11的內部，從而利用雷射的加工進一步向深度方向進行。藉此，在穿孔部11中，相對於表面的開口徑R1而深度變大。
其後，將第二構件20填充於第一構件10的穿孔部11中，並使該第二構件20固化。藉此，將第一構件10及第二構件20接合，而形成接合構造體100（參照圖1）。再者，第二構件20例如是藉由射出成形、熱板熔著、雷射熔著、澆鑄硬化、超音波熔著、或振動熔著而接合。 （第二實施方式）
繼而，參照圖3，對本發明的第二實施方式的接合構造體200進行說明。
接合構造體200如圖3所示，是接合有由不同材料所構成的第一構件30及第二構件20者。在第一構件30的表面33形成有具有開口的穿孔部31，且在該穿孔部31的內周面形成有向內側突出的突出部32。此外，在第一構件30的穿孔部31中填充並固化有第二構件20。
第二實施方式的穿孔部31是以在深度方向（Z方向）上開口徑自表面33側朝向底部314變小的縮徑部311、在深度方向上開口徑自表面33側朝向底部314變大的擴徑部312、及在深度方向上開口徑自表面33側朝向底部314變小的縮徑部313相連的方式而形成。縮徑部311是以直線狀縮徑的方式而形成，擴徑部312是以曲線狀擴徑的方式而形成，縮徑部313是以曲線狀縮徑的方式而形成。
此外，自表面33側朝向底部314側依序配置有縮徑部311、擴徑部312及縮徑部313。因此，在穿孔部31中，縮徑部311與擴徑部312的邊界部分的開口徑（內徑）R4變得小於表面33的開口徑R3、及擴徑部312與縮徑部313的邊界部分的開口徑R5。藉此，將突出部32配置於進入底部314側的位置。該突出部32例如是跨周方向上的全長而形成，且形成為環狀。
再者，第一構件30的其他構成與所述的第一構件10相同。 -接合構造體的製造方法-
繼而，參照圖3及圖4，對第二實施方式的接合構造體200的製造方法進行說明。
首先，如圖4所示，藉由對第一構件30的表面33照射一個脈衝由多個次脈衝所構成的雷射，而在第一構件30的表面33形成穿孔部31，並且在該穿孔部31的內周面形成突出部32。此時，若形成突出部32，則將雷射的反射波封閉於穿孔部31的內部，從而利用雷射的加工進一步向深度方向進行。藉此，在穿孔部31中，相對於表面的開口徑R3而深度變大。
再者，在第二實施方式中，與第一實施方式不同，是將突出部32配置於進入底部314側的位置，此種不同例如是由第一構件30的材料或雷射照射條件等的不同所引起。
其後，將第二構件20填充於第一構件30的穿孔部31中，並使該第二構件20固化。藉此，將第一構件30及第二構件20接合，而形成接合構造體200（參照圖3）。再者，第二構件20例如是藉由射出成形、熱板熔著、雷射熔著、澆鑄硬化、超音波熔著、或振動熔著而接合。 -實驗例-
繼而，參照圖5及圖6，對為了確認所述的第二實施方式的效果而進行的實驗例1及實驗例2進行說明。 [實驗例1]
在該實驗例1中，製作對應於第二實施方式的實施例1～實施例4的接合構造體500（參照圖6）與比較例1的接合構造體，並對各接合構造體進行接合評價。再者，作為接合評價，對未進行熱衝擊試驗的接合構造體測定接合強度，並且對熱衝擊試驗後的接合構造體測定接合強度，基於該測定結果判定合格與否。將其結果示於表1。 [表1]
首先，對實施例1～實施例4的接合構造體500的製作方法進行說明。
在實施例1～實施例4的接合構造體500中，使用SUS304作為第一構件501的材料。該第一構件501如圖5所示，是形成為板狀，長度為100 mm，寬度為29 mm，厚度為3 mm。
然後，對第一構件501的表面的既定區域R照射雷射。該既定區域R是接合接合構造體500的面積，設為12.5 mm×20 mm。實施例1～實施例4所共通的雷射的照射條件如以下所述。
＜雷射照射條件＞ 雷射：光纖雷射（波長1062 nm） 頻率：10 kHz 輸出：3.8 W 掃描速度：650 mm/sec 掃描次數：20次 照射間隔：65 μm
另外，如表1所示，在實施例1中，將次脈衝數設定為20個，並且將次脈衝的一個週期設定為15.0 ns。在實施例2中，將次脈衝數設定為2個，並且將次脈衝的一個週期設定為15.0 ns。在實施例3中，將次脈衝數設定為20個，並且將次脈衝的一個週期設定為10.5 ns。在實施例4中，將次脈衝數設定為50個，並且將次脈衝的一個週期設定為15.0 ns。
再者，頻率是由多個次脈衝所構成的脈衝的頻率。即，在該照射條件中，1秒內移動650 mm，並且以65 μm的間隔照射1萬次雷射（脈衝），該脈衝由多個次脈衝所構成。再者，掃描次數是對相同部位重複照射雷射的次數。另外，在實施例1、實施例2及實施例4中，一次次脈衝的照射時間為7.5 ns，次脈衝的照射間隔為7.5 ns。另外，在實施例3中，一次次脈衝的照射時間為3 ns，次脈衝的照射間隔為7.5 ns。
如上所述，藉由照射一個脈衝由多個次脈衝所構成的雷射，而在第一構件501的表面的既定區域R形成穿孔部，並且在該穿孔部形成突出部。
然後，藉由插入成形，將第二構件502接合於第一構件501的表面。在實施例1～實施例4的接合構造體500中，使用PBT（溫泰克聚合物（WinTech Polymer）製造的DURANEX（註冊商標）3316）作為第二構件502的材料。另外，成形機是使用日本製鋼所製造的J35EL3。成形條件如以下所述。
＜成形條件＞ 預乾燥：120℃×5小時 模具溫度：120℃ 氣缸溫度：270℃ 保壓：100 MPa
以所述方式製作實施例1～實施例4的接合構造體500。再者，第二構件502是形成為板狀，長度為100 mm，寬度為25 mm，厚度為3 mm。
繼而，對比較例1的接合構造體的製作方法進行說明。
在比較例1的接合構造體中，作為第一構件及第二構件的材料，使用與實施例1～實施例4相同的材料，並且成形條件亦設為相同的設定。此外，在比較例1的接合構造體中，使用無脈衝控制功能的光纖雷射形成穿孔部。即，藉由照射一個脈衝不由多個次脈衝所構成的雷射（單一脈衝）而形成穿孔部。因此，在比較例1的第一構件中形成研缽狀（圓錐狀）的穿孔部。
然後，對實施例1～實施例4的接合構造體500及比較例1的接合構造體進行接合評價。
再者，接合強度是使用英斯特朗（Instron）製造的機電式萬能試驗機5900進行測定。具體而言，關於剪切方向是以拉伸速度5 mm/min進行試驗，以第二構件的斷裂或接合界面的斷裂結束試驗。此外，採用該試驗中的最大強度作為接合強度。
另外，熱衝擊試驗是使用愛斯佩克（ESPEC）製造的冷熱衝擊裝置TSD-100進行。具體而言，重複進行100次-40℃下30分鐘的低溫曝露與85℃下30分鐘的高溫曝露。
此外，為了判斷在熱循環環境下的可靠性，而按照以下的基準進行合格與否的判斷。
合格（○）：「熱衝擊試驗後的接合強度」/「熱衝擊試驗前的接合強度」≧90%
不合格（×）：「熱衝擊試驗後的接合強度」/「熱衝擊試驗前的接合強度」＜90%
如所述的表1所示，實施例1～實施例4的接合構造體500與比較例1的接合構造體相比，相對於表面的開口徑而穿孔部的深度變大。其原因在於：在實施例1～實施例4的接合構造體500中，藉由照射一個脈衝由多個次脈衝所構成的雷射，而在穿孔部上形成突出部，因此將雷射的反射波封閉於穿孔部的內部，從而利用雷射的加工進一步向深度方向進行。
此外，實施例1～實施例4的接合構造體500在熱衝擊試驗的前後，接合強度高於比較例1的接合構造體。認為其原因在於：在實施例1～實施例4的接合構造體500中，藉由相對於表面的開口徑而穿孔部的深度大，錨定效應變大，從而接合強度提高。
進而，判明在實施例1～實施例4的接合構造體500中，在熱衝擊試驗後亦可將熱衝擊試驗前的接合強度維持90%以上。相對於此，在比較例1的接合構造體中，在熱衝擊試驗後接合強度大幅降低。因此，如實施例1～實施例4的接合構造體500般，藉由利用一個脈衝由多個次脈衝所構成的雷射形成深的穿孔部，而可實現在熱循環環境下的耐久性的提高。 [實驗例2]
在該實驗例2中，製作對應於第二實施方式的實施例5～實施例8的接合構造體與比較例2的接合構造體，並對各接合構造體進行接合評價。再者，接合評價是以與實驗例1相同的方式進行。將其結果示於表2。 [表2]
在該實驗例2中，變更第一構件的材料而區別於實驗例1。具體而言，在實驗例2的接合構造體中，使用PPS（聚塑膠（Polyplastics）製造的FORTRON（註冊商標）1140）作為第一構件的材料。另外，伴隨第一構件的材料的變更，將實施例5～實施例8所共通的雷射照射條件設為如以下所述。
＜雷射照射條件＞ 雷射：光纖雷射（波長1062 nm） 頻率：10 kHz 輸出：1.1 W 掃描速度：650 mm/sec 掃描次數：3次 照射間隔：65 μm
另外，如表2所示，在實施例5中，將次脈衝數設定為20個，並且將次脈衝的一個週期設定為15.0 ns。在實施例6中，將次脈衝數設定為2個，並且將次脈衝的一個週期設定為15.0 ns。在實施例7中，將次脈衝數設定為20個，並且將次脈衝的一個週期設定為10.5 ns。在實施例8中，將次脈衝數設定為50個，並且將次脈衝的一個週期設定為15.0 ns。
如所述的表2所示，實施例5～實施例8的接合構造體與比較例2的接合構造體相比，相對於表面的開口徑而穿孔部的深度變大。其原因在於：在實施例5～實施例8的接合構造體中，藉由照射一個脈衝由多個次脈衝所構成的雷射，而在穿孔部上形成突出部，因此將雷射的反射波封閉於穿孔部的內部，從而利用雷射的加工進一步向深度方向進行。
此外，實施例5～實施例8的接合構造體在熱衝擊試驗的前後，接合強度高於比較例2的接合構造體。認為其原因在於：在實施例5～實施例8的接合構造體中，藉由相對於表面的開口徑而穿孔部的深度大，錨定效應變大，從而接合強度提高。
進而，判明在實施例5～實施例8的接合構造體中，在熱衝擊試驗後亦可將熱衝擊試驗前的接合強度維持90%以上。相對於此，在比較例2的接合構造體中，在熱衝擊試驗後接合強度大幅降低。即，即便在使用作為樹脂的PPS作為第一構件的材料的情形時，藉由利用一個脈衝由多個次脈衝所構成的雷射形成深的穿孔部，而可實現接合強度的提高，並且可實現在熱循環環境下的耐久性的提高。 （其他實施方式）
再者，此次揭示的實施方式在所有方面均為例示，並非成為限定性解釋的根據。因此，本發明的技術範圍並不僅由所述的實施方式解釋，而是基於申請專利範圍的記載而劃定。另外，在本發明的技術範圍中，包括與申請專利範圍相同的含義及範圍內的全部變更。
例如，在第一實施方式中，表面13可平坦，亦可彎曲。再者，第二實施方式亦為同樣。
另外，在第一實施方式中，示出了以擴徑部111與縮徑部112相連的方式形成的例，但並不限於此，亦可在擴徑部與縮徑部之間形成沿深度方向筆直延伸的部分。再者，第二實施方式亦為同樣。
另外，在第一實施方式中，示出了穿孔部11的周圍平坦的例，但並不限於此，亦可如圖7所示的第一變化例的第一構件10a般，在穿孔部11的開口的周圍形成有自表面13向上方隆起的隆起部14。隆起部14是以包圍穿孔部11的周圍的方式形成，在俯視下形成為大致圓形。該隆起部14例如在照射一個脈衝由多個次脈衝所構成的雷射時，藉由堆積經熔融的第一構件10a而形成。若以此種方式構成，則藉由隆起部14亦會產生錨定效應，因此可進一步提高接合強度。再者，第二實施方式亦為同樣。
另外，在第一實施方式中，示出了穿孔部11的軸心垂直於表面13的例，但並不限於此，亦可如圖8所示的第二變化例的第一構件10b般，以穿孔部11b的軸心相對於表面13傾斜的方式而形成。在穿孔部11b的內周面形成有向內側突出的突出部12b。該穿孔部11b例如是藉由使雷射的照射方向相對於表面13傾斜（45°以上且小於90°）的方式而形成。藉此，即便在形成穿孔部11b的區域的上方存在照射雷射時的障礙物的情形時，亦可形成穿孔部11b。再者，第二實施方式亦為同樣。
另外，在第一實施方式中，示出了在穿孔部11形成一個突出部12的例，但並不限於此，亦可如圖9所示的第三變化例的第一構件10c般，在穿孔部11c形成有多個突出部121c及突出部122c。該穿孔部11c例如可變更雷射的輸出條件，藉由對相同部位照射雷射而形成。若以此種方式構成，則穿孔部11c的表面積變大，並且形成多個突出部121c及突出部122c，藉此可進一步提高接合強度。再者，在圖9中，突出部是121c及122c的兩個部位，但亦可形成三個部位以上。再者，第二實施方式亦為同樣。
另外，亦可如圖10所示的第一實施方式的第四變化例的第一構件10d般，藉由位置錯開的多次雷射照射而形成一個穿孔部11d。即，亦可藉由使藉由雷射照射而形成的穿孔部的一部分重疊而形成一個穿孔部11d。在穿孔部11d的內周面形成有向內側突出的突出部12d。再者，第二實施方式亦為同樣。另外，亦可適當組合所述的第一變化例～第四變化例。 [產業上之可利用性]
