Description

電子模組、連接體的製造方法以及電子模組的製造方法
本發明有關於電子模組、連接體的製造方法以及電子模組的製造方法。
以往,在封裝樹脂內配置有多個電子元件的電子模組已被普遍認知(例如,參照日本專利特開2014-45157號)。這種電子模組被要求實現小型化。
作為實現小型化的手段之一,可以考慮採用將電子元件疊層。當疊層時,可以考慮在電子元件(第一電子元件)的一側(例如正面側)配置連接體,並在該連接體的一側通過焊錫等導電性黏合劑配置別的電子元件(第二電子元件)。
由於在第一電子元件的一側配置有這樣的連接體,因此可能出現重量失衡。而一旦連接體引發這種重量失衡,就可能會導致導電性黏合劑流出至連接體的一側的面。
另外,當在配置在第一電子元件上的連接體上進一步配置第二電子元件時,由於熱量容易聚集,因此使電子元件之間相互隔開是比較有益的。

《製造方法》
下面將對本實施方式涉及的第一連接體60的製造方法的一例進行說明。
首先,將導體板300載置在具有模具凹部410的模具400上(第一載置步驟,參照第8圖(a))。
接著,通過按壓構件等將導體板300向模具400按壓後,將對應模具凹部410的第一柱部62形成在導體板300的另一側上(第一柱部形成步驟,參照第8圖(b))。此時,導體板300被朝模具凹部410一側折彎,並在導體板300的一側上的與第一柱部62相對應的位置上形成第一凹部67。另外,在第8圖(b)、(c)中對導體板300的折彎情況作了誇張處理。
接著,通過將具有突出部460的按壓構件450向導體板300的一側按壓,從而在導體板300的一側的面上形成第一溝槽部64(第一溝槽部形成步驟,參照第8圖(c))。通過上述按壓,導體板300邊緣部向模具凹部410一側的折彎就得以被矯正,從而變為接近平坦的形狀,形成第一平坦面69。
另外,形成第一平坦面69的步驟和形成第一溝槽部64的步驟可以分別來進行。例如,可以在通過按壓構件形成第一平坦面69後,再通過對突出部460這樣的構件進行按壓來形成第一溝槽部64,也可以在第一溝槽部64形成後,再形成第一平坦面69。
接下來,對本實施方式涉及的第二連接體70的製造方法的一例進行說明。與第一連接體60的製造方法一樣,將使用第8圖來進行說明。
首先,將導體板300載置在具有模具凹部410的模具上(第二載置步驟,參照第8圖(a))。
接著,在將導體板300向模具按壓後,將對應模具凹部410的第二柱部72形成在導體板300的另一側上(第二柱部形成步驟,參照第8圖(b))。此時,導體板300被朝模具凹部410一側折彎,並在導體板300的一側上的與第二柱部72相對應的位置上形成第二凹部77。另外,在第8圖(b)、(c)中對導體板300的折彎情況作了誇張處理。
接著,通過將具有突出部460的按壓構件450向導體板300的一側按壓,從而在導體板300的一側的面上形成第二溝槽部74(第二溝槽部形成步驟,參照第8圖(c))。通過上述按壓,導體板300邊緣部向模具凹部410一側的折彎就得以被矯正,從而變為接近平坦的形狀,形成第二平坦面79。
另外,形成第二平坦面79的步驟和形成第二溝槽部74的步驟可以分別來進行。例如,可以在通過按壓構件形成第二平坦面79後,再通過對突出部460這樣的構件進行按壓來形成第二溝槽部74,也可以在第二溝槽部74形成後,再形成第二平坦面79。
接著,對本實施方式涉及的電子模組的製造方法的一例進行說明。該製造方法中使用的第一連接體60以及第二連接體70可以使用上述製造步驟中製造的第一連接體以及第二連接體。
首先,在第一夾具500上配置第一電子元件13(第一電子元件配置步驟,參照第9圖(a))。
接著,在第一電子元件13上通過焊錫等導電性黏合劑配置第一連接體60(第一連接體配置步驟,參照第9圖(b))。第9圖中未圖示有焊錫等導電性黏合劑。
接著,在第一連接體60上通過導電性黏合劑配置第二電子元件23(第二電子元件配置步驟,參照第9圖(c))。第一連接體60上的導電性黏合劑被配置在第一電子元件13的第一溝槽部64的邊緣內側。
在第二夾具550上配置第二連接體70(第二電子元件配置步驟,參照第9圖(d))。第二夾具550可以在配置有第二連接體70的位置上具有多個第二夾具凹部560。第二夾具凹部560的高度可以與芯片模組的高度相對應。這裡所說的第二夾具凹部560的高度與芯片模組的高度相對應,指的是第二夾具凹部560具有大於等於包含導電性黏合劑的厚度在內的芯片模組的整體設計上的厚度的高度。
接著,在利用吸引構件將第二連接體70吸附並固定在第二夾具550上後使第二夾具550翻轉,然後,在第二電子元件23上通過導電性黏合劑配置第二連接體70(翻轉載置步驟,參照第9圖(e))。
接著,對導電性黏合劑硬化(硬化步驟)。這樣,具有第一電子元件13以及第二電子元件23的芯片模組便得以被製造。
當第一電子元件13以及第二電子元件23被封裝入由封裝樹脂等構成的封裝部90中時,將芯片模組載置在第一基板11與第二基板21之間,並通過在第一基板11與第二基板21之間注入由封裝樹脂等構成的封裝部90後,本實施方式的電子模組便得以被製造。
《作用・效果》
接下來,將對由上述結構構成的本實施方式的作用以及效果進行說明。另外,可以將在《作用・效果》中說明的任何形態適用於上述結構。
如第3圖所示,在採用在第一頭部61的一側的面上配置有第一溝槽部64的形態的情況下,就能夠防止導電性黏合劑溶融後擴散至第一溝槽部64的外部。
另外,如上述製造步驟中的說明般,在形成第一柱部62時導體板300會被折彎,如第8圖(c)所示,在對該折彎進行校正時會形成第一溝槽部64。在本實施方式中是以第一溝槽部64作為邊界來形成第一凹部67與第一平坦面69的。當採用此形態時,有益於在導電性黏合劑溶融後一邊使導電性黏合劑留在第一凹部67內,一般將第一平坦面69切實地配置在邊緣外側。通過使導電性黏合劑留在第一凹部67內,有益於確保導電性黏合劑的厚度。而通過配置第一平坦面69,就能夠將第二電子元件23沿第一平坦面69在面方向上進行配置,這樣就有益於使來自於第一連接體60的應力不易被施加至第二電子元件23。
當採用第一溝槽部64從平面上看(在面方向上)被配置在第一柱部62的整個邊緣外側的形態時,就能夠更加切實地防止導電性黏合劑溶融後流出至邊緣外側。
當採用第一連接體60具有第一柱部62的形態時,就能夠使第一電子元件13與第二電子元件23在一定程度上相互隔開,這樣就有益於熱量的逃散。在本實施方式中,通過形成這樣的第一柱部62,就能夠進一步形成第一凹部67。其結果就是,能夠使溶融後的導電性黏合劑留在第一凹部67內,從而有益於防止溶融後的導電性黏合劑流出至邊緣外側。
另外,第二連接體70也與第一連接體60一樣,如上述製造步驟中的說明般,在形成第二柱部72時導體板300會被折彎,如第8圖(c)所示,在對該折彎進行校正時會形成第二溝槽部74。在本實施方式中是以第二溝槽部74作為邊界來形成第二凹部77與第二平坦面79的。當採用此形態時,有益於在導電性黏合劑溶融後一邊使導電性黏合劑留在第二凹部77內,一般將第二平坦面79切實地配置在邊緣外側。
當採用第二連接體70具有從第二頭部71向另一側延伸的第二柱部72的形態時,就能夠在第二電子元件23的一側設置空間,從而防止來自於第二電子元件23的熱量產生聚集。在本實施方式中,通過形成這樣的第二柱部72,就能夠進一步形成第二凹部77。其結果就是,能夠使溶融後的導電性黏合劑留在第二凹部77內,從而有益於防止溶融後的導電性黏合劑流出至邊緣外側。
當採用第二溝槽部74從平面上看(在面方向上)被配置在第二柱部72的整個邊緣外側的形態時,就能夠更加切實地防止導電性黏合劑溶融後流出至邊緣外側。
如第3圖(b)所示,當第一溝槽部64的截面呈矩形時,就能夠將第一溝槽部64的表面與第一凹部67的表面所形成的角度設置為90的程度。由於這樣能夠加強導電性黏合劑的表面張力,因此就能夠使導電性黏合劑不易在第一凹部67內流動。同樣的,如第4圖(b)所示,當第第二溝槽部74的截面呈矩形時,就能夠將第二溝槽部74的表面與第二凹部77的表面所形成的角度設置為90的程度。由於這樣能夠加強導電性黏合劑的表面張力,因此就能夠使導電性黏合劑不易在第二凹部77內流動。
如第3圖(a)所示,當第一溝槽部64的截面呈三角形時,就能夠較容易地來形成第一溝槽部64,並且有益於較容易地來形成第一平坦面69。同樣的,如第4圖(a)所示,當第二溝槽部74的截面呈三角形時,就能夠較容易地來形成第二溝槽部74,並且有益於較容易地來形成第二平坦面79。
當第一平坦面69傾斜,使其越向邊緣外側越遠離包含第二方向以及第三方向的面時,通過第一平坦面69的傾斜也有益於能夠防止溶融後的導電性黏合劑流向第一連接體60的邊緣外側。同樣的,當第二平坦面79傾斜,使其越向邊緣外側越遠離包含第二方向以及第三方向的面時,通過第二平坦面79的傾斜也有益於能夠防止溶融後的導電性黏合劑流向第二連接體70的邊緣外側。
第二實施方式
接下來,對本發明的第二實施方式進行說明。
在第一實施方式中,第一溝槽部64被配置在第一傾斜面68與第一平坦面69的邊界上,並且第二溝槽部74被配置在第二傾斜面78與第二平坦面79的邊界上。而在本實施方式中,如第10圖至第12圖所示,第一溝槽部64被配置在第一凹部67的邊緣外側,並且第一溝槽部64被配置在第一平坦面69上,第二溝槽部74被配置在第二凹部77的邊緣外側,並且第二溝槽部74被配置在第二平坦面79上。關於本實施方式中的其他結構,由於與第一實施方式相同,因此能夠採用第一實施方式中已進行過說明的的任何一種形態。另外,已在第一實施方式中說明的構件在本實施方式中將使用同一符號來進行說明。
在本實施方式中,為了將第一溝槽部64配置在第一平坦面69上,將第二溝槽部74配置在第二平坦面79上,與第一實施方式中的形態相比,突出部460相對於模具凹部410的邊緣部,位於更邊緣外側的位置上(參照第12圖(c))。
如本實施方式般,當採用第一溝槽部64被配置在第一凹部67的邊緣外側,並且第一溝槽部64被配置在第一平坦面69上的形態的情況下,通過第一凹部67來防止溶融後的導電性黏合劑擴散至邊緣外側的同時,即便是導電性黏合劑流出至第一凹部67的邊緣外側的情況下,也能夠通過第一溝槽部64來防止該導電性黏合劑擴散至邊緣外側。
同樣的,當採用第二溝槽部74被配置在第二凹部77的邊緣外側,並且第二溝槽部74被配置在第二平坦面79上的形態的情況下,通過第二凹部77來防止溶融後的導電性黏合劑擴散至邊緣外側的同時,即便是導電性黏合劑流出至第二凹部77的邊緣外側的情況下,也能夠通過第二溝槽部74來防止該導電性黏合劑擴散至邊緣外側。
第三實施方式
接下來,對本發明的第三實施方式進行說明。
與第一實施方式以及第二實施方式不同,在本實施方式中,第一溝槽部64被配置在第一傾斜面68上,第二溝槽部74被配置在第二傾斜面78上。關於本實施方式中的其他結構,由於與上述各實施方式相同,因此能夠採用上述各實施方式中已進行過說明的的任何一種形態。另外,已在上述各實施方式中說明的構件在本實施方式中將使用同一符號來進行說明。
如實施方式所示,通過第一溝槽部64被配置在第一傾斜面68上,就有益於抑制導電性黏合劑從第一凹部67中流出。同樣的,通過第二溝槽部74被配置在第二傾斜面78上,就有益於抑制導電性黏合劑從第二凹部77中流出。
在以縱截面觀看時,如第13圖所示,第一傾斜面68與第一溝槽部64的內周側的面所形成的角度α1可以小於第一傾斜面68與第一溝槽部64的外周側的面所形成的角度β1。此情況下,由於能夠將第一傾斜面68與第一溝槽部64的內周側的面所形成的角度設置得更小,並加強導電性黏合劑所具有的表面張力,因此就能夠使導電性黏合劑不易在第一溝槽部64內流動,進而有益於防止導電性黏合劑向邊緣外側擴散。
同樣的,如第14圖所示,第二傾斜面78與第二溝槽部74的內周側的面所形成的角度α2可以小於第一傾斜面68與第二溝槽部74的外周側的面所形成的角度β2。此情況下,由於能夠將第二傾斜面78與第二溝槽部74的內周側的面所形成的角度設置得更小,並加強導電性黏合劑所具有的表面張力,因此就能夠使導電性黏合劑不易在第二溝槽部74內流動,進而有益於防止導電性黏合劑向邊緣外側擴散。
另外,在第一實施方式以及第二實施方式中,也可以是第一頭部61的一側面(第一平坦面69或第一傾斜面68)與第一溝槽部64的內周側的面所形成角度小於第一頭部61的一側面與第一溝槽部64的外周側的面所形成角度。同樣的,也可以是第二頭部71的一側面(第二平坦面79或第二傾斜面78)與第二溝槽部74的內周側的面所形成角度小於第二頭部71的一側面與第二溝槽部74的外周側的面所形成角度。
在上述各實施方式中,雖然使用了同一種形態對第一連接體60中第一溝槽部64與第一傾斜面68以及第一平坦面69之間的關係、以及第二連接體70中第二溝槽部74與第二傾斜面78以及第二平坦面79之間的關係進行了說明,但並不僅限於此。例如,也可以是第一連接體60為第一實施方式中的形態,而第二連接體70為第二實施方式或第三實施方式中的形態。也可以是第二連接體70為第一實施方式中的形態,而第一連接體60為第二實施方式或第三實施方式中的形態。還可以將這樣形態任意組合。
第四實施方式
接下來,對本發明的第四實施方式進行說明。
雖然在上述各本實施方式中,使用的是截面呈T字形的第一連接體60,但在本實施方式中,如第16圖所示,具有從第一頭部61向另一側延伸的四個支撐部65(65a-65d)。支撐部65與第一導體層12或第一基板11抵接。關於本實施方式中的其他結構,由於與上述各實施方式相同,因此能夠採用上述各實施方式中已進行過說明的的任何一種形態。另外,已在上述各實施方式中說明的構件在本實施方式中將使用同一符號來進行說明。
雖然在本實施方式是以使用四個支撐部65的形態來進行說明的,但並不僅限於此,也可以使用一個、兩個、三個或五個以上的支撐部65。
在如本實施方式般配置有從第一頭部61延伸的支撐部65的情況下,就能夠防止在第二電子元件23安裝時或安裝後因第二電子元件23的重量導致第一連接體60發生傾斜。另外,通過這樣的支撐部65與第一導體層12或第一基板11抵接,還能夠提高散熱性。特別是當支撐部65與第一導體層12抵接的情況下,有益於進一步提升散熱效果。
在如本實施方式般配置有多個支撐部65的情況下,就能夠更加穩定地來配置第一連接體60,並且有益於實現更高的散熱效果。
支撐部65可以各自在面方向上延伸,並具有與第一基板11或第一導體層12抵接的支撐基端部169(169a-169d)。另外,可以不必在每個支撐部65上都配置支撐基端部169,而是僅在多個支撐部65中的一部分支撐部65上配置支撐基端部169,而其餘的支撐部65上不配置支撐基端部169。
在像這樣配置有支撐基端部169的情況下,就能夠將第一連接體60更穩定得配置在第一基板11或第一導體層12上,並且還能夠通過支撐基端部169來增加與第一基板11或第一導體層12的接觸面積,從而提高散熱效果。
支撐部65可以各自與第一導體層12抵接。當個與支撐部65相連接的第一導體層12不與別的第一導體層12、第二導體層22、第一電子元件13以及第二電子元件23電氣連接從而不發揮電氣功能時,有益於防止第一電子元件13以及第二電子元件23顯示支撐部65導通後出現預料外的運作。
當如本實施方式般使用支撐部65時,如第5圖、第10圖以及第13圖所示,第一頭部61在其邊緣外側具有第一平坦面69是有益的。當第一頭部61的邊緣外側沿第一方向傾斜時,可能無法切實地使支撐部65與第一導體層12或第一基板11抵接。而當第一頭部61在其邊緣外側具有第一平坦面69時,就能夠切實地使支撐部65與第一導體層12或第一基板11抵接,這樣有益於通過支撐部65來實現提升穩定性的效果以及實現提升散熱性的效果。從此觀點來看,第一平坦面69在面方向上的傾斜角度較小則比較理想,第一平坦面69在面方向上的傾斜角度的理想狀態例如小於等於3度。
另外,通過配置第一溝槽部64,有益於使第一平坦面69切實地沿面方向延伸。特別是如第一實施方式般當第一溝槽部64位於第一平坦面69與第一傾斜面68的邊界上時,有益於進一步減小第一平坦面69在面方向上的傾斜角度。另外,如第二實施方式般當第一溝槽部64被配置在第一平坦面69上時,有益於進一步切實的使第一平坦面69在邊緣外側的面方向上的角度比第一溝槽部64更小。
支撐部65可以各自具有從第一頭部61向面方向延伸的面方向支撐部166(166a-166d)、以及從面方向支撐部166向高度方向(第一方向)延伸的高度方向支撐部165(165a-165d)(參照後述的第六實施方式)。另外,面方向支撐部166指的是在寬度方向上的長度比第一頭部61更短的部分。
支撐部65可以不具有面方向支撐部166,而僅具有從第一頭部61向高度方向(第一方向)延伸的高度方向支撐部165。
第五實施方式
接下來,對本發明的第五實施方式進行說明。
雖然在上述各實施方式中,使用了具有第二柱部72且截面呈T字形的第二連接體70,但在本實施方式中,如第17圖所示,第二連接體70具有從第二頭部71向另一側延伸的延伸部75(75a、75b)。關於本實施方式中的其他結構,由於與上述各實施方式相同,因此能夠採用上述各實施方式中已進行過說明的的任何一種形態。另外,已在上述各實施方式中說明的構件在本實施方式中將使用同一符號來進行說明。
雖然在本實施方式中對使用了兩個延伸部75的形態進行說明,但並不僅限於此,也可以使用一個或三個以上的延伸部75。
根據本實施方式,由於配置有延伸部75,因此能夠有效地將來自於第二電子元件23的熱量進行散熱,並通過第二連接體70實現高散熱性。當如本實施方式般配置有多個延伸部75時,有益於實現更高的散熱性。
延伸部75可以各自與第一導體層12抵接。與延伸部75相連接的第一導體層12可以不與別的第一導體層12、第二導體層22、第一電子元件13以及第二電子元件23電氣連接。
延伸部75可以各自在面方向上延伸,並具有與第一基板11或第一導體層12抵接的延伸基端部179(179a、179b)。另外,可以不必在每個延伸部75上都配置延伸基端部179,而是僅在多個延伸部75中的一部分延伸部75上配置延伸基端部179,而其餘的延伸部75上不配置延伸基端部179。
在像這樣配置有延伸基端部179的情況下,就能夠將第二連接體70更平衡地配置在第一基板11或第一導體層12上,並且還能夠通過延伸基端部179來增加與第一基板11或第一導體層12的接觸面積,從而提高散熱效果。
在如本實施方式般採用具有延伸部75的情況下,如第6圖、第11圖以及第14圖所示,第二頭部71在其邊緣外側具有第二平坦面79是有益的。當第二頭部71的邊緣外側沿第一方向傾斜時,可能無法切實地使延伸部75與第一導體層12或第一基板11抵接。而當第二頭部71在其邊緣外側具有第二平坦面79時,就能夠切實地使延伸部75與第一導體層12或第一基板11抵接,這樣有益於通過延伸部75來實現提升穩定性的效果以及實現提升散熱性的效果。從此觀點來看,第二平坦面79在面方向上的傾斜角度較小則比較理想,第二平坦面79在面方向上的傾斜角度的理想狀態例如小於等於3度。
另外,通過配置第二溝槽部74,有益於使第二平坦面79切實地沿面方向延伸。特別是如第一實施方式般當第二溝槽部74位於第二平坦面79與第二傾斜面78的邊界上時,有益於進一步減小第二平坦面79在面方向上的傾斜角度。另外,如第二實施方式般當第二溝槽部74被配置在第二平坦面79上時,有益於進一步切實的使第二平坦面79在邊緣外側的面方向上的角度比第二溝槽部74更小。
通過採用本實施方式,就能夠通過延伸部75來施加將第二基板21推回一側的排斥力。雖然因加熱會對第一基板11以及第二基板21施加產生翹曲變形的力,但通過使用具有多伸部75(特別是多個延伸部75)的第二連接體70,就有益於防止第一基板11以及第二基板21產生翹曲變形。
另外,本實施方式中的延伸部75還具有從第二頭部71向高度方向(第一方向)延伸的高度方向延伸部175(175a、175b)。
第六實施方式
接下來,對本發明的第六實施方式進行說明。
雖然在第四實施方式中配置有支撐部65,在第五實施方式中配置有延伸部75,但也可以同時採用支撐部65以及延伸部75。在本實施方式中,如第18圖至第20圖所示,採用了具有三個支撐部65以及三個延伸部75的形態。關於本實施方式中的其他結構,由於與上述各實施方式相同,因此能夠採用上述各實施方式中已進行過說明的的任何一種形態。另外,已在上述各實施方式中說明的構件在本實施方式中將使用同一符號來進行說明。
如本實施方式所示,延伸部75可以具有從第二頭部71向面方向延伸的面方向延伸部176(176a-176c)、以及從面方向延伸部176向高度方向(第一方向)延伸的高度方向延伸部175(175a-175c)。另外,面方向延伸部176指的是在寬度方向上的大小比第二頭部71更小的部分。
在本實施方式中,在第一連接體60 的一側的面上配置有第一溝槽部64,而在第二連接體70上則未配置有第二溝槽部74。但也不僅限於此形態,也可以是在第二連接體70的一側的面上配置有第二溝槽部74,而在第一連接體60上則未配置有第一溝槽部64。
