再者,本申請案可使用空間對應語詞,例如「之下」、「低於」、「較低」、「高於」、「較高」等類似語詞之簡單說明,以描述圖式中一元件或特徵與另一元件或特徵的關係。空間對應語詞係用以包括除了圖式中描述的位向之外,裝置於使用或操作中之不同位向。裝置或可被定位(旋轉90度或是其他位向),並且可相應解釋本申請案使用的空間對應描述。
本文所述之實施例可討論為特定內容,稱為具有扇出或扇入晶圓層級封裝。其他實施例考量其他應用,例如不同的封裝型式或是不同的架構,其對於該技藝之技術人士而言在讀取本揭露之後係為明顯的。應理解本文所述的實施例不需要說明存在於結構中的每個組件或特徵。例如,當討論組件之一可足以傳達實施例的各方面時,可在圖式中省略複數個相同的組件。再者,本文所述的方法實施例之討論係以特定順序進行;然而,其他方法實施例可以任何邏輯順序進行。
圖1至6係根據一些實施例說明一般製程的中間結構之剖面圖,用以說明各種一般概念。圖1係說明第一區40與第二區42,切割線區44係在第一區40與第二區42之間。如圖所示,在圖1說明支 撐結構46,以及在支撐結構46上的第一介電層48。例如,支撐結構46可包含形成在第一區40與第二區42中的各種結構。此結構可包含晶片、封裝的晶片、基板、或類似物。此結構的範例及其形成係如圖12至34所示。第一介電層48可為聚合物,例如聚苯并噁唑(polybenzoxazole,PBO)、聚亞醯胺、苯并環丁烯(benzocyclobutene,BCB)、或類似物,其進一步可為光敏材料,並且可使用任何可接受的沉積製程,例如旋塗或類似方法,而沉積。
在圖2中,第一介電層48的形成進一步包含圖案化第一介電層48。該圖案化可為可接受的製程,例如當介電層為光敏材料時,將第一介電層48暴露於光,並且顯影第一介電層48。圖案化在切割線區44中產生第一層虛擬塊50與分隔區52。為清楚說明,在此範例中的第一層虛擬塊50係自第一介電層48形成,並且係得自於第一介電層48的圖案化。因此,第一層虛擬塊50的材料可與第一介電層48之材料相同。在其他實施例中,在圖案化第一介電層48之後,例如藉由於切割線區44中沉積且圖案化該材料而形成第一虛擬塊50。在一些其他實施例中,第一層虛擬塊50的材料可與第一介電層48之材料不同。
分隔區52係將切割線區44中的第一層虛擬塊50自第一區40與第二區42中的第一介電層48分離。例如,切割線區44的尺寸54範圍係自約400微米至約500微米。第一層虛擬塊50的尺寸56,例如寬度之範圍可自約200微米至約320微米。分隔區52的尺寸58係自第一層虛擬塊50的側壁至第一區40或第二區42其中之一中第一介電層48的對應側壁,尺寸58之範圍可自約50微米至約400微米。
在圖3中,例如,金屬化圖案60可包含重佈線(RDL),金屬化圖案60係形成在第一區40中與第二區42中的第一介電層48上。在形成金屬化圖案60的範例中,晶種層(未繪示)係形成在第一介電層48上方。在一些實施例中,晶種層係金屬層,其可為單層或 是複合層,其包括由不同材料所形成的複數個次層。在一些實施例中,晶種層包括鈦層以及在鈦層上方的銅層。例如,可使用物理氣相沉積(PVD)或類似方法,形成晶種層。而後,在晶種層上,形成且圖案化光阻。可藉由旋塗或類似方法形成光阻,並且可將其暴露至光用於圖案化。光阻的圖案係對應於金屬化圖案60。圖案化形成穿過光阻的開口,以暴露晶種層。在光阻的開口中以及在晶種層的暴露部分上,形成傳導材料。可藉由鍍,例如電鍍或無電鍍、或類似方法,形成傳導材料。傳導材料可包括金屬,如銅、鈦、鎢、鋁、或類似物。而後,移除光阻以及未有傳導材料形成於其上之晶種層的部分。可藉由可接受的灰化或剝離製程,例如使用氧氣電漿或類似物,移除光阻。一旦移除光阻後,藉由例如使用可接受的蝕刻製程,例如濕式或乾式蝕刻,移除晶種層之暴露部分。晶種層與傳導材料的剩餘部分係形成金屬化圖案60。
在圖4中,在第一區40與第二區42中的第一介電層48與金屬化圖案60上,沉積第二介電層62。在分隔區52中以及在切割線區44中的第一層虛擬塊50上,進一步沉積第二介電層62。第二介電層62可為聚合物,例如PBO、聚亞醯胺、BCB、或類似物,其可進一步為光敏材料,並且可使用任何可接受的沉積製程,例如旋塗或類似方法,而沉積。在一些情況下,例如使用旋塗,所形成的第二介電層62可能不具有均勻的平坦表面,例如在第二介電層62可填充凹槽之處,例如分隔區52。如圖4所示,由於分隔區52的存在,第二介電層62在切割線區44中具有凹處。相較於沒有第一層虛擬塊50的類似情況,切割線區44中的第一層虛擬塊50係提供堅固的結構支撐與填充物,其可減少凹處64。
在圖5中,第二介電層62的形成進一步包含將第二介電層62圖案化。圖案化為可接受的製程,例如當介電層係光敏材料 時,將第二介電層62暴露至光並且顯影第二介電層62。圖案化係在切割線區44中的第一層虛擬塊50上產生第二層虛擬塊66。為清楚說明,在此範例中,從第二介電層62形成第二層虛擬塊66,其係來自於將第二介電層62圖案化而得。因此,第二層虛擬塊66的材料可與介電層62的材料相同。在其他的實施例中,在圖案化第二介電層62之後,可藉由例如在切割線區44中的第一層虛擬塊50上沉積另一材料並且將該材料圖案化,而形成第二層虛擬塊66。在一些其他實施例中,第二層虛擬塊66的材料可與第二介電層62的材料不同。
在第二介電層62上未使用例如旋塗而進一步形成介電層的一些實施例中,可省略第二層虛擬塊66。在此情況中,不需要第二層虛擬塊66作為形成另一介電層過程中之堅固的結構支撐或是填充物。在第二介電層62上使用例如旋塗而形成一或多個其他介電層之其他實施例中,可存在第二層虛擬塊66,並且視需要而有其他層虛擬塊。在此情況中,第二層虛擬塊66與/或其他層虛擬塊可提供堅固的結構支撐與填充物,用於形成一或多個後續形成之介電層。
由於在形成第二介電層62過程中有第一層虛擬塊50存在,接近切割線區44的邊緣區68中的第二介電層62之厚度可比第二介電層62之剩餘部分的厚度更均勻。例如,在邊緣區68的第二介電層62之厚度可偏離在第一區40(或第二區42)之中心處的第二介電層62之厚度,偏離範圍在約百分之70至約百分之80內。在第二介電層62形成過程中有第一層虛擬塊50存在,可減少凹處64的深度,其而後減少在邊緣區68中第二介電層62上的效應。例如若無第一層虛擬塊50存在,第二介電層62形成過程中的凹處深度越大,則凹處對於第二介電層62的邊緣區68上的效應越大。例如,若深度大,則邊緣區68中可發生非常薄的第二介電層62,其可造成接近邊緣區68的金屬化圖案60之覆蓋與絕緣不足,其因而可造成裝置故障。有第一層虛擬塊50存在,可不顯 著不利影響在邊緣區68的第二介電層62厚度,其可防止裝置故障。
在圖6中,在切割線區44中進行切割70。切割70可自第二區42將第一區40切割,例如以個別的支撐結構46、第一介電層48、金屬化圖案60、以及第二介電層62,成為個別的封裝組件。封裝組件可為基板、晶片級封裝(CSP)、積體扇出(扇入)封裝、或類似物。如圖所示,切割70可穿過第一層虛擬塊50以及第二層虛擬塊66(若有),其可造成第一層虛擬塊72與第二層虛擬塊74保留在各個切割的封裝組件上的切割線區44之剩餘部分中。分隔區52可在切割70過程中防止鋸子接觸第一區40與第二區42中的第一介電層48與第二介電層62,其可協助減少切割所造成的第一區40與第二區42中第一介電層48與第二介電層62之脫層。該技藝中具有通常技術者可理解在切割之前,切割區典型環繞封裝組件,並且一旦切割之後,第一層虛擬塊72、第二層虛擬塊74以及分隔區52可環繞各個第一區40與第二區42。圖1至6所述之一般方面在圖12至34的範例內容中變得更清楚,然而這些方面可應用於不同的結構與製程中。
圖7A至7D係根據一些實施例說明第二層虛擬塊(或其他層虛擬塊)的一些範例修飾。X-Y-Z軸係用於清楚說明且便於討論。圖7A係說明沿著X-Z平面的剖面圖,類似於圖5所示的剖面圖。圖5與7A中描述且編碼相同的組件,為求簡要,省略該些組件之討論。在圖5中,第二層虛擬塊66與第一層虛擬塊50在X與Y方向具有共同邊界。例如,第二層虛擬塊66可為第二層中之第一層虛擬塊50的複製,並且可使用相同遮罩用於圖案化第一層虛擬塊50與第二層虛擬塊66。在圖7A中,以及圖7B至7D中的其他說明,第二層虛擬塊76在X方向並未與第一層虛擬塊50共邊界,以及在Y方向也可無共邊界。在圖7A中,第二層虛擬塊76的尺寸78,例如在X方向的寬度,係小於第一層虛擬塊50在相同的X方向的尺寸。在一些實施例中,第二層虛擬塊76 的尺寸78與第一層虛擬塊50的尺寸54之比例範圍係自約0.5至約0.95。
第二層虛擬塊76的範例係如圖7B至7D中的佈局圖式所示。在圖7B中,第二層虛擬塊76a於Y方向係與第一層虛擬塊50共邊界,以及在X方向未與第一層虛擬塊50共邊界。在圖7C中,第二層虛擬塊76b於Y方向未與第一層虛擬塊50共邊界,以及在X方向未與第一層虛擬塊50共邊界。在圖7D中,多個分隔的第二層虛擬塊76c係在第一層虛擬塊50上,且於Y方向對準。各個第二層虛擬塊76c於X方向未與第一層虛擬塊50共邊界。
圖8A至8D係根據一些實施例說明第二層虛擬塊(或其他層虛擬塊)的一些其他範例修飾。X-Y-Z軸係用於清楚說明且便於討論。圖8A係說明沿著X-Z平面的剖面圖,類似於圖5所示的剖面圖。圖5與8A中描述且編碼相同的組件,為求簡要,省略該些組件之討論。在圖8A中,以及藉由圖8B至8D中的進一步說明,第二層虛擬塊係包括至少第一部分80與第二部分82,其係沿著第一層虛擬塊50的中間而分隔。再者,接近分隔區52的第一部分80之側壁係未對準接近相同分隔區52的第一層虛擬塊50之側壁,以及接近分隔區52的第二部分82之側壁係未對準接近相同分隔區52的第一層虛擬塊50之側壁。
第二層虛擬塊之第一部分80與第二部分82的範例係如圖8B至8D的佈局圖式所示。在圖8B中,第一部分80a與第二部分82a係各自於Y方向與第一層虛擬塊50共邊界。在圖8C中,第一部分80a與第二部分82a係各自於Y方向未與第一層虛擬塊50共邊界。在圖8D中,多個分隔的第一部分80c與多個分隔的第二部分82c係在第一層虛擬塊50上,並且分別於Y方向對準。
藉由如圖7A至7D與8A至8D所示之具有第二層(或後續層)虛擬塊,可減少錯誤對準的考量,同時達到如前所述之堅固的結構支撐與填充物。
圖9至11係說明由Y方向切割線區88與X方向切割線區90所分割的陣列中之多個封裝組件區86的佈局圖式。圖9至11的線A-A係說明圖1至6、7與8A的範例剖面圖。圖9至11係分別說明第一層虛擬塊92、94與96的架構。第二層(或後續層)虛擬塊可具有關於如前所述之第一層虛擬塊92、94或96的任何架構。在圖9中,連續的第一層虛擬塊92係沿著Y方向切割線區88與X方向切割線區90連續延伸。藉由沿著Y方向切割線區88延伸之連續的第一層虛擬塊92之一部分以及沿著X方向切割線區90延伸之連續的第一層虛擬塊92之一部分,在Y方向切割線區88與X方向切割線區90的交叉處,形成連續的第一層虛擬塊92的交叉處。在圖10中,不讓第一層虛擬塊94沿著封裝組件區86之對應邊緣實質延伸,並且不實質延伸至Y方向切割線區88與X方向切割線區90交叉的交叉區中。在圖11中,多個分離的第一層虛擬塊94係對準於個別的Y方向切割線區88與X方向切割線區90。
圖12至34係根據一些實施例說明形成封裝上封裝(PoP)製程之中間步驟的剖面圖式。圖12係說明載體基板100以及形成在載體基板100上的釋放層102。如圖所示,第一封裝區300與第二封裝區302係分別用於形成第一封裝與第二封裝。切割線區304係在第一封裝區300與第二封裝區302之間。該技藝中具有通常技術者可理解切割線區可環繞各個第一封裝區300與第二封裝區302,以及可理解關於切割線區304的討論同樣應用於其他切割線區。
載體基板100可為玻璃載體基板、陶瓷載體基板、或類似物。載體基板100可為晶圓,因而可於載體基板100上同時形成多個封裝。釋放層102可由聚合物為基底的材料形成,可沿著載體基板100從後續步驟中所形成的下方層將其移除。在一些實施例中,釋放層102係環氧化合物為基底的熱釋放材料,當加熱時,會喪失其黏性,例如光熱轉換(LTHC)釋放塗層。自其他實施例中,釋放層102可 為紫外光(UV)膠,當暴露至UV光時,會喪失其黏性。釋放層102可為液體且被硬化、可為壓層於載體基板100上的壓層膜、或是可為類似物。釋放層102的頂部表面可為平整的,並且可具有高程度的共平面性。

積體電路晶粒114進一步包括墊122,例如鋁墊,其係用於外部連接。墊122係在積體電路晶粒114的個別主動側上。鈍化膜124係在積體電路114上以及在墊122的部分上。開口係穿過鈍化膜124至墊122。晶粒連接物126,例如傳導柱(包括金屬,例如銅),係在穿過鈍化膜124的開口中,並且係機械耦合且電耦合至個別墊122。例如,可藉由鍍或類似方法,形成晶粒連接物126。晶粒連接物126係電 耦合積體電路晶粒114的個別積體電路。

在圖21中,而後將介電層140圖案化。圖案化形成開口,以暴露部分的金屬化圖案138。圖案化為可接受的製程,例如當介電層係光敏材料時,將介電層140暴露至光,或是使用非等向性蝕刻之蝕刻方法。若介電層140係光敏材料,則可在曝光之後,將介電層140顯影。圖案化進一步在第一層虛擬塊134上以及在切割線區304中的分隔區136之間,形成第二層虛擬塊144。第二層虛擬塊144可具有圖1至6、7A至7D、8A至8D、以及9至11所示之任何架構或是所述之各方面。
在圖22中,在介電層140上,形成具有通路之金屬化圖案146。在形成金屬化圖案146的範例中,在介電層140上方以及在介電層140的開口中,形成晶種層(未繪示)。在一些實施例中,晶種層係金屬層,其可為單層或是複合層,其包括由不同材料所形成的複數個次層。在一些實施例中,晶種層包括鈦層以及在鈦層上方的銅層。例如,可使用PVD或類似方法,形成晶種層。而後,在晶種層上,形成且圖案化光阻。可藉由旋塗或類似方法形成光阻,並且可將光阻暴露至光用於圖案化。光阻的圖案係對應於金屬化圖案146。圖案化形成穿過光阻的開口,以暴露晶種層。在光阻的開口中以及在晶種層的暴露部分上,形成傳導材料。可藉由鍍,例如電鍍或是無電鍍、或類似方法,形成傳導材料。傳導材料可包括金屬,例如銅、鈦、鎢、鋁或類似物。而後,移除光阻以及未有傳導材料形成於其上的晶種層之部分。藉由可接受的灰化或剝離製程,例如使用氧氣電漿 或類似方法,移除光阻。一旦移除光阻,使用可接受的蝕刻製程,例如濕式或乾是蝕刻,移除晶種層的暴露部分。晶種層的剩餘部分以及傳導材料形成金屬化圖案146與通路。在穿過介電層140至例如部分的金屬化圖案138之開口中,形成通路。
在圖23中,在金屬化圖案146與介電層140上,沉積介電層148。在一些實施例中,介電層148可為聚合物,其可為光敏材料,例如PBO、聚亞醯胺、BCB、或類似物,可使用微影蝕刻遮罩而輕易將其圖案化。可藉由旋塗或類似方法,沉積介電層148。由於有介電層132與140中的分隔區136,在沉積過程中,可在介電層148的頂部表面中形成凹處150。
在圖24中,而後將介電層148圖案化。圖案化形成開口,以暴露部分的金屬化圖案146。圖案化為可接受的製程,例如當介電層係光敏材料時,將介電層148暴露至光,或是使用非等向性蝕刻之蝕刻製程。若介電層148係光敏材料,可在曝光之後,將介電層148顯影。圖案化進一步在第一層虛擬塊134與第二層虛擬塊144上以及在切割線區304中的分隔區136之間,形成第三層虛擬塊152。第三層虛擬塊152可具有如圖1至6、7A至7D、8A至8D、以及9至11所示之任何架構或所述之方面。
在圖25中,在介電層148上,形成具有通路的金屬化圖案154。在形成金屬化圖案154的範例中,在介電層148上方以及穿過介電層148的開口中,形成晶種層(未繪示)。在一些實施例中,晶種層係金屬層,其可為單層或是複合層,其包括由不同材料所形成的複數個次層。在一些實施例中,晶種層包括鈦層以及在鈦層上方的銅層。例如,可使用PVD或類似方法,形成晶種層。而後,在晶種層上,形成且圖案化光阻。可藉由旋塗或類似方法形成光阻,並且將光阻暴露至光用於圖案化。光阻的圖案係對應於金屬化圖案154。圖案化形成穿過光阻的開口,以暴露晶種層。在光阻的開口中以及在晶種 層的暴露部分上,形成傳導材料。可藉由鍍,例如電鍍或無電鍍、或類似方法,形成傳導材料。傳導材料可包括金屬,如銅、鈦、鎢、鋁、或類似物。而後,移除光阻以及未有傳導材料形成於其上的晶種層之部分。藉由可接受的灰化或剝離製程,例如使用氧氣電漿或類似方法,移除光阻。一旦移除光阻,例如使用可接受的蝕刻製程,例如濕式或乾式蝕刻,移除晶種層的暴露部分。晶種層的剩餘部分以及傳導材料形成金屬化圖案154與通路。在穿過介電層148至例如部分的金屬化圖案146的開口中,形成通路。
在圖26中,在金屬化圖案154與介電層148上,沉積介電層156。在一些實施例中,介電層156可為聚合物,其可為光敏材料,例如PBO、聚亞醯胺、BCB、或類似物,可使用微影蝕刻遮罩而輕易將其圖案化。可藉由旋塗或類似方法,沉積介電層156。由於介電層132、140與148中有分隔區136,在沉積過程中,可在介電層156的頂部表面中形成凹處158。
在圖27中,而後將介電層156圖案化。圖案化形成開口,以暴露部分的金屬化圖案154。圖案化為可接受的製程,例如當介電層係光敏材料時,將介電層156暴露至光,或是使用非等向性蝕刻的蝕刻方法。若介電層156係光敏材料,在曝光之後,可將介電層156顯影。介電層156的圖案化係從切割線區304移除介電層156。如後所示,介電層156上不再沉積介電層,因此,可省略對應於介電層156的層虛擬塊。
前側重佈結構160係一範例。可在前側重佈結構160中,形成更多或較少的介電層與金屬化圖案。若欲形成較少的介電層與金屬化圖案,則可省略上述的步驟與製程。若欲形成更多的介電層與金屬化圖案,則可重複上述的步驟與製程。該技藝中具有通常技術者理解可省略或重佈該些步驟與製程。
類似於圖5所述,在上方介電層,例如介電層140、 148與156,的沉積過程中,由於有個別的虛擬塊134、144與152存在,接近切割線區304的邊緣區中的上方介電層之厚度係比介電層之剩餘部分的厚度更均勻。可降低凹處142、150與158的深度,而後減少在邊緣區中的個別介電層上的效應。有虛擬塊134、144與152存在,不會顯著不利影響在邊緣區的介電層140、148與156之厚度,其可防止裝置故障。
在圖28中,在前側重佈結構160的外側上,形成墊162,其可稱為凸塊下金屬層(UBM)。在所述之實施例中,形成穿過開口的墊162,該開口穿過介電層156至金屬化圖案154。在形成墊162的範例中,在介電層156上方,形成晶種層(未繪示)。在一些實施例中,晶種層係金屬層,其可為單層或是複合層,其包括由不同材料所形成的複數個次層。在一些實施例中,晶種層包括鈦層以及在鈦層上方的銅層。例如,可使用PVD或類似方法,形成晶種層。而後,在晶種層上,形成且圖案化光阻。可藉由旋塗或類似方法形成光阻,並且將光阻暴露至光用於圖案化。光阻的圖案係對應於墊162。圖案化形成穿過光阻的開口,以暴露該晶種層。在光阻的開口中以及在晶種層的暴露部分上,形成傳導材料。可藉由鍍,例如電鍍或是無電鍍、或類似方法,形成傳導材料。傳導材料可包括金屬,如銅、鈦、鎢、鋁、或類似物。而後,移除光阻以及未有傳導材料形成於其上的晶種層之部分。藉由可接受的灰化或剝離製程,例如使用氧氣電漿或類似方法,移除光阻。一旦移除光阻,使用可接受的蝕刻製程,例如濕式或乾式蝕刻,移除晶種層的暴露部分。晶種層的剩餘部分以及傳導材料形成墊162。
在圖29中,在墊162上,形成外部電連接物164,例如焊球,如球柵陣列(BGA)球。外部電連接物164可包含低溫回銲材料,例如焊料,其可為無鉛或是含鉛。可使用適當的植球製程,形成外部電連接物164。在一些實施例中,可省略墊162,並且可在金屬化 圖案154上直接形成外部電連接物164穿過開口,該開口穿過介電層156。
在圖30中,進行載體基板脫層,使載體基板100從背側重佈結構110,例如介電層104,脫離(脫層)。根據一些實施例,脫層包含將光投射在釋放層102上,光例如雷射光或是UV光,因而釋放層102在光熱之下分解,並且可移除載體基板100。而後,翻轉基板並且將其置放在膠帶170上方。
在圖31中,形成穿過介電層104的開口,以暴露部分的金屬化圖案106。可使用雷射鑽孔、蝕刻、或類似方法,形成開口。
在圖32中,使用外部電連接物182,將封裝180附接至第一封裝區300與第二封裝區302各自中的背側重佈結構110。封裝180可為以及/或包括任何封裝組件。例如,如圖所示,封裝180各自包括基板、在基板上之兩個堆疊的積體電路晶粒、將積體電路晶粒電耦合至基板的的打線接合、以及封裝積體電路晶粒與打線接合的封裝物。在一範例中,封裝180的積體電路晶粒係記憶體晶粒,例如動態隨機存取記憶體(DRAM)晶粒。封裝180係藉由附接至穿過開口之金屬化圖案106的外部電連接物182而電耦合且機械耦合至背側重佈結構110,該開口係穿過介電層104。在一些實施例中,外部電連接物182可包含低溫可回銲材料,例如焊料,例如無鉛銲料,以及在其他實施例中,外部電連接物182可包含金屬柱。在一些實施例中,外部電連接物182係受控塌陷晶片連接(C4)凸塊、微凸塊、或類似物。在一些實施例中,可將外部電連接物182回銲,用以將封裝182附接至金屬化圖案106。例如,封裝180的積體電路晶粒係經由封裝180中的打線接合與基板、外部電連接物182、背側重佈結構110、貫穿通路112、以及前側重佈結構160,而電耦合且通訊耦合至積體電路晶粒114。
再者,在圖32中,藉由沿著切割線區304鋸而進行切 割製程。鋸184將第一封裝區300自第二封裝區302切割。圖33係說明所得之切割的封裝上封裝(PoP)結構。切割造成封裝200,其可來自於被切割的第一封裝區300或第二封裝區302。如圖所示,封裝180係附接至封裝200的背側重佈層110。封裝200沿著切割線區的剩餘區具有分別對應於虛擬塊134、144與152之剩餘的虛擬部分186、188與190,該切割線區例如切割線區304。在鋸184過程中,分隔區136可防止鋸到封裝區中的介電層132、140、148與156,該封裝區例如第一封裝區300或第二封裝區302,其有助於減少切割所誘發的介電層132、140、148與156之脫層。
在圖34中,PoP結構係附接至基板202。外部電連接物164係電耦合且機械耦合至基板202上的墊204。例如,基板202可為印刷電路板(PCB)或類似物。
