技術領域
本公開涉及(ji)一(yi)種線圈(quan)組件及(ji)制(zhi)造(zao)該線圈(quan)組件的方法。
背景技術:
根據諸如數字(zi)電視(TV)、移動電話和膝上型(xing)(xing)計算機等的電子(zi)裝(zhuang)置的小型(xing)(xing)化和輕(qing)薄(bo)化,在這(zhe)樣(yang)(yang)的電子(zi)裝(zhuang)置中使用的線(xian)(xian)圈組件(jian)相應地需要(yao)被小型(xing)(xing)化和輕(qing)薄(bo)化。為了(le)尋(xun)求這(zhe)樣(yang)(yang)的組件(jian),已(yi)經積極地進行了(le)各種纏繞式或薄(bo)膜式線(xian)(xian)圈組件(jian)的研究和開發。
作為線圈組件的小型化和輕薄化的一部分,小型化和輕薄化的線圈組件除了小型化和輕薄化之外還需要提供與現有線圈組件的特性等同的特性。為了滿足這樣的需求,需要確保具有足夠尺寸的具有低直流(DC)阻抗Rdc并(bing)在(zai)其中填充有磁性材(cai)料的芯部。為了實現該目的,已經使用例(li)如各向異性鍍覆技術來(lai)開發具有更(geng)大(da)的高寬比(bi)的線(xian)(xian)圈圖案以及具有更(geng)大(da)的截(jie)面面積的線(xian)(xian)圈部的線(xian)(xian)圈組件。
然而(er),當由于(yu)小型化(hua)和輕(qing)薄化(hua)的需求而(er)在有限的空間(jian)中使用各向(xiang)異性鍍(du)覆(fu)技(ji)術制造(zao)線圈組件時,由于(yu)高寬比的增加導致(zhi)增加了缺(que)陷(xian)的風(feng)險(xian),包括由于(yu)鍍(du)覆(fu)生長的均勻性下降和線圈部(bu)之(zhi)間(jian)短路的出現等導致(zhi)的缺(que)陷(xian)。

第一線圈層211和221的線圈圖案的導體的截面部分可具有小于1的高寬比(AR)(厚度h1與寬度w1的比(h1/w1),其中,h1是與支撐構件230的使第一線圈層211和221設置在其上的背對的表面正交進行測量的,w1是與所述背對的表面平行進行測量的)。第二線圈層212和222的線圈圖案的導體的截面部分可具有大于1的高寬比(AR)(厚度h2與寬度w2的比(h2/w2),其中,h2是與支撐構件230的使第一線圈層211和221設置在其上的背對的表面正交進行測量的,w2是與所述背對的表面平行進行測量的)。也就是說,在根據示例的線圈組件10A中,第一線圈層211和221以及第二線圈層212和222的線圈圖案的導體的截面部分可彼此不同。例如,第一線圈層211和221的線圈圖案的導體的截面部分可具有大約的160μm至190μm的寬度w1和大約60μm至90μm的厚度h1,第二線圈層212和222的線圈圖案的導體的截面部分可具有大約的60μm至90μm寬度w2和大約90μm至120μm的厚度h2。
同時,在諸如電感器的線圈組件的主要特性中,直流(DC)阻抗Rdc特性可隨著線圈部200的截面面積增大而減小。此外,電感可隨著主體部100中的使磁通量通過的磁性區域的面積增大而變大。因此,為了減小DC阻抗Rdc并增加電感,需要增大線圈部200的截面面積,并且需要增大磁性區域的面積。作為增加線圈部200的截面面積的方法,具有增大線圈圖案的導體的寬度(例如,w1和w2)的方法以及增大線圈圖案的導體的厚度(例如,h1和h2)的(de)(de)(de)(de)方法。然而(er),在僅(jin)僅(jin)增大線圈(quan)(quan)(quan)圖(tu)案的(de)(de)(de)(de)導體(ti)(ti)的(de)(de)(de)(de)寬度的(de)(de)(de)(de)情況(kuang)下,具有將(jiang)出現(xian)(xian)在相鄰的(de)(de)(de)(de)線圈(quan)(quan)(quan)圖(tu)案之(zhi)間短路(lu)的(de)(de)(de)(de)風險(xian)。此(ci)外,在可實(shi)現(xian)(xian)的(de)(de)(de)(de)線圈(quan)(quan)(quan)圖(tu)案的(de)(de)(de)(de)匝(za)數方面(mian)(mian)產(chan)生(sheng)限(xian)(xian)(xian)制(zhi)(zhi),并(bing)減小了磁性(xing)區域占據的(de)(de)(de)(de)面(mian)(mian)積,使得效率降低,并(bing)且,還在實(shi)現(xian)(xian)高電感產(chan)品方面(mian)(mian)產(chan)生(sheng)限(xian)(xian)(xian)制(zhi)(zhi)。為(wei)了克服這(zhe)些限(xian)(xian)(xian)制(zhi)(zhi),已經需要(yao)在不增大線圈(quan)(quan)(quan)圖(tu)案導體(ti)(ti)的(de)(de)(de)(de)寬度的(de)(de)(de)(de)情況(kuang)下通過增大線圈(quan)(quan)(quan)圖(tu)案導體(ti)(ti)的(de)(de)(de)(de)厚度而(er)獲得的(de)(de)(de)(de)具有高的(de)(de)(de)(de)高寬比的(de)(de)(de)(de)線圈(quan)(quan)(quan)圖(tu)案導體(ti)(ti)的(de)(de)(de)(de)實(shi)現(xian)(xian)。
同(tong)時(shi)(shi),圖(tu)34是示(shi)出使應用了各向(xiang)(xiang)同(tong)性(xing)鍍(du)(du)覆(fu)技術的(de)(de)(de)(de)線(xian)(xian)圈(quan)組件的(de)(de)(de)(de)示(shi)例的(de)(de)(de)(de)示(shi)意圖(tu)。應用了各向(xiang)(xiang)同(tong)性(xing)鍍(du)(du)覆(fu)技術的(de)(de)(de)(de)線(xian)(xian)圈(quan)組件可通過下述(shu)方法(fa)來制造:例如,通過各向(xiang)(xiang)同(tong)性(xing)鍍(du)(du)覆(fu)技術在(zai)(zai)(zai)支撐構(gou)件1030的(de)(de)(de)(de)背對的(de)(de)(de)(de)表面(mian)(mian)上(shang)形成均呈平(ping)面(mian)(mian)線(xian)(xian)圈(quan)形狀的(de)(de)(de)(de)線(xian)(xian)圈(quan)圖(tu)案(an)1021和1022;使用磁性(xing)材料包埋線(xian)(xian)圈(quan)圖(tu)案(an)1021和1022,以(yi)形成主體(ti)部1010;在(zai)(zai)(zai)主體(ti)部1010的(de)(de)(de)(de)外表面(mian)(mian)上(shang)形成分別電連接到線(xian)(xian)圈(quan)圖(tu)案(an)1021和1022的(de)(de)(de)(de)外電極(ji)1041和1042。然(ran)而,由于在(zai)(zai)(zai)執(zhi)行電鍍(du)(du)方法(fa)的(de)(de)(de)(de)同(tong)時(shi)(shi)執(zhi)行鍍(du)(du)覆(fu),使得(de)線(xian)(xian)圈(quan)圖(tu)案(an)在(zai)(zai)(zai)厚度方向(xiang)(xiang)和寬度方向(xiang)(xiang)同(tong)時(shi)(shi)生長,因此(ci)各向(xiang)(xiang)同(tong)性(xing)鍍(du)(du)覆(fu)技術在(zai)(zai)(zai)實現如圖(tu)34所示(shi)的(de)(de)(de)(de)高(gao)的(de)(de)(de)(de)高(gao)寬比方面(mian)(mian)存在(zai)(zai)(zai)限制。
同時圖35是示(shi)出(chu)應(ying)用了(le)各向(xiang)(xiang)異(yi)(yi)性(xing)鍍(du)覆技(ji)術的(de)(de)(de)線(xian)圈(quan)(quan)組件(jian)的(de)(de)(de)示(shi)例的(de)(de)(de)示(shi)意圖。應(ying)用了(le)各向(xiang)(xiang)異(yi)(yi)性(xing)鍍(du)覆技(ji)術的(de)(de)(de)線(xian)圈(quan)(quan)組件(jian)可(ke)通過下(xia)面的(de)(de)(de)方向(xiang)(xiang)來制造:例如,通過各向(xiang)(xiang)異(yi)(yi)性(xing)鍍(du)覆技(ji)術在(zai)(zai)支撐構件(jian)2030的(de)(de)(de)背(bei)對的(de)(de)(de)表(biao)面上(shang)形(xing)(xing)成分(fen)別(bie)具有平面線(xian)圈(quan)(quan)形(xing)(xing)狀的(de)(de)(de)線(xian)圈(quan)(quan)圖案2021和(he)(he)2022;使用磁性(xing)材料包埋(mai)線(xian)圈(quan)(quan)圖案2021和(he)(he)2022,以(yi)形(xing)(xing)成主體部(bu)2010;在(zai)(zai)主體部(bu)2010的(de)(de)(de)外表(biao)面上(shang)形(xing)(xing)成分(fen)別(bie)電連接到線(xian)圈(quan)(quan)圖案2021和(he)(he)2022的(de)(de)(de)外電極(ji)2041和(he)(he)2042。然(ran)而,在(zai)(zai)應(ying)用了(le)各向(xiang)(xiang)異(yi)(yi)性(xing)鍍(du)覆技(ji)術的(de)(de)(de)情況(kuang)下(xia),雖然(ran)可(ke)實現高的(de)(de)(de)高寬(kuan)比,但由于高寬(kuan)比的(de)(de)(de)增(zeng)大會導致鍍(du)覆生長的(de)(de)(de)均勻性(xing)降低,并且鍍(du)覆厚度的(de)(de)(de)分(fen)布(bu)變(bian)寬(kuan),使得(de)會容易出(chu)現相鄰線(xian)圈(quan)(quan)繞(rao)組或(huo)圖案之間的(de)(de)(de)短路(lu)。
另一方面,作為根據示例的線圈組件10A,在第一線圈層211和221的線圈圖案導體的高寬比小于1的情況下,可在用于形成線圈圖案的工藝技術所允許的分布之內自由地調整線圈圖案的寬度和高度,使得線圈圖案導體的均勻性可以是優異的,并且,線圈圖案導體可在寬度方向上變寬,使得線圈部的導體的截面面積增加,從而可實現低DC阻抗Rdc特性(xing)。此外,在第(di)二線(xian)(xian)圈(quan)層(ceng)212和(he)222的(de)(de)(de)(de)線(xian)(xian)圈(quan)圖(tu)案(an)(an)導(dao)體(ti)的(de)(de)(de)(de)高寬比大(da)于1的(de)(de)(de)(de)情(qing)況下,第(di)二線(xian)(xian)圈(quan)層(ceng)212和(he)222的(de)(de)(de)(de)線(xian)(xian)圈(quan)圖(tu)案(an)(an)可(ke)在相同的(de)(de)(de)(de)平(ping)面(mian)上均具有比第(di)一線(xian)(xian)圈(quan)層(ceng)211和(he)221的(de)(de)(de)(de)線(xian)(xian)圈(quan)圖(tu)案(an)(an)的(de)(de)(de)(de)匝(或(huo)(huo)繞組(zu))數(shu)(shu)更高的(de)(de)(de)(de)匝(或(huo)(huo)繞組(zu))數(shu)(shu)。也就(jiu)是(shi)說,形成線(xian)(xian)圈(quan)部的(de)(de)(de)(de)各個(ge)繞組(zu)的(de)(de)(de)(de)導(dao)體(ti)的(de)(de)(de)(de)截(jie)面(mian)面(mian)積減小,但可(ke)進一步增加匝(或(huo)(huo)繞組(zu))數(shu)(shu),這對實現高電感(gan)特別有利。
此外(wai),在根據示例的(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)組件(jian)10A中,第(di)一(yi)(yi)(yi)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)211和(he)221的(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)圖(tu)案(an)導(dao)體的(de)(de)高(gao)寬(kuan)比可(ke)小于1,使得(de)第(di)一(yi)(yi)(yi)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)211和(he)221的(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)圖(tu)案(an)導(dao)體的(de)(de)厚度(du)可(ke)以基本上是薄(bo)的(de)(de),第(di)二(er)(er)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)212和(he)222的(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)圖(tu)案(an)導(dao)體的(de)(de)高(gao)寬(kuan)比可(ke)大(da)于1,但第(di)二(er)(er)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)212和(he)222的(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)圖(tu)案(an)導(dao)體的(de)(de)線(xian)(xian)(xian)(xian)(xian)寬(kuan)本身可(ke)薄(bo)薄(bo)地(di)實現,使得(de)第(di)二(er)(er)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)212和(he)222的(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)圖(tu)案(an)導(dao)體的(de)(de)寬(kuan)度(du)可(ke)以不是非(fei)常厚。此外(wai),為了具有足夠的(de)(de)匝(或(huo)繞組)數,各個(ge)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)211、221、212和(he)222可(ke)形成為在水平(ping)方(fang)(fang)(fang)向(xiang)(xiang)(xiang)(xiang)(即,第(di)一(yi)(yi)(yi)方(fang)(fang)(fang)向(xiang)(xiang)(xiang)(xiang)和(he)/或(huo)第(di)二(er)(er)方(fang)(fang)(fang)向(xiang)(xiang)(xiang)(xiang)(例如(ru),與支撐構件(jian)230的(de)(de)使第(di)一(yi)(yi)(yi)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)211和(he)221設(she)置在其上的(de)(de)背對的(de)(de)表面(mian)平(ping)行的(de)(de)方(fang)(fang)(fang)向(xiang)(xiang)(xiang)(xiang)))上盡(jin)可(ke)能多地(di)利用空(kong)間(jian)。也(ye)就是說,在豎直(zhi)方(fang)(fang)(fang)向(xiang)(xiang)(xiang)(xiang)上堆疊的(de)(de)第(di)一(yi)(yi)(yi)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)211和(he)221以及第(di)二(er)(er)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)212和(he)222可(ke)具有重疊的(de)(de)區域(yu)。因此,可(ke)實現薄(bo)的(de)(de)并(bing)具有足夠的(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)特性的(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)組件(jian)。
第一線圈層211和221的線圈圖案導體可具有如上所述的小于1的高寬比(厚度h1與寬度w1的比(h1/w1))。此外,第一線圈層211和221的線圈圖案的匝(或繞組)數可以是一匝。這里,匝數是一匝的含義是匝數等于或小于1(例如,不完全匝)。另一方面,第二線圈層212和222的線圈圖案導體可具有如上所述的大于1的高寬比(厚度h2與寬度w2的比(h2/w2))。此(ci)外,第(di)二線(xian)(xian)圈(quan)(quan)層212和222的線(xian)(xian)圈(quan)(quan)圖案的匝(za)(za)(或繞組)數(shu)可以是(shi)多匝(za)(za)。這里,匝(za)(za)數(shu)是(shi)多匝(za)(za)的含(han)義是(shi)匝(za)(za)數(shu)大(da)于1。因此(ci),如上所述(shu),線(xian)(xian)圈(quan)(quan)部的截面面積減小,但可進一步增加匝(za)(za)數(shu),這樣對實現(xian)高電感特別有利。
當(dang)第一線(xian)圈(quan)(quan)層211和(he)(he)221的線(xian)圈(quan)(quan)圖(tu)案(an)的匝數(shu)是x并且(qie)第二線(xian)圈(quan)(quan)層212和(he)(he)222的線(xian)圈(quan)(quan)圖(tu)案(an)的匝數(shu)是y時,y與x的比(bi)(y/x)可(ke)(ke)(ke)以是2或更(geng)大。例如,y與x的比(bi)(y/x)可(ke)(ke)(ke)以是大約(yue)2至3(或者在2至3的范(fan)圍)。在這(zhe)種情況下,可(ke)(ke)(ke)克服(fu)各向同(tong)性鍍覆技術(shu)和(he)(he)各向異性鍍覆技術(shu)的缺點,可(ke)(ke)(ke)增(zeng)加匝數(shu),使得可(ke)(ke)(ke)實現更(geng)高水平的電感(gan)。

只要支(zhi)(zhi)撐構(gou)件(jian)230可(ke)支(zhi)(zhi)撐多個線圈層211、212、221和(he)222,不具體地限定(ding)支(zhi)(zhi)撐構(gou)件(jian)230的(de)(de)材料或(huo)種(zhong)類。例如(ru),支(zhi)(zhi)撐構(gou)件(jian)230可(ke)以(yi)是(shi)覆(fu)銅板(ban)(ban)(CCL)、聚(ju)丙二醇(chun)(PPG)基(ji)板(ban)(ban)、鐵氧體基(ji)板(ban)(ban)或(huo)金屬(shu)基(ji)軟(ruan)磁基(ji)板(ban)(ban)等。此(ci)外,支(zhi)(zhi)撐構(gou)件(jian)230可(ke)以(yi)是(shi)由絕緣(yuan)樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)形成(cheng)的(de)(de)絕緣(yuan)基(ji)板(ban)(ban)。絕緣(yuan)樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)可(ke)以(yi)是(shi)諸如(ru)環(huan)氧樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)的(de)(de)熱(re)固性樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)、諸如(ru)聚(ju)酰亞胺樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)的(de)(de)熱(re)塑(su)性樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)、具有浸漬在(zai)熱(re)固性樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)和(he)熱(re)塑(su)性樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)中的(de)(de)諸如(ru)玻璃纖維或(huo)無機填充劑的(de)(de)加強材料的(de)(de)樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)(諸如(ru)半固化片、ABF(Ajinomoto Build up Film)、FR-4、雙(shuang)馬來(lai)酰亞胺三嗪(BT)樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)或(huo)光可(ke)成(cheng)像電介質(PID,photo-imageable dielectric)樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi))等。包括玻璃纖維和(he)環(huan)氧樹(shu)(shu)(shu)(shu)脂(zhi)(zhi)(zhi)的(de)(de)絕緣(yuan)基(ji)板(ban)(ban)可(ke)用于(yu)(yu)剛度保持方面,但(dan)不限于(yu)(yu)此(ci)。支(zhi)(zhi)撐構(gou)件(jian)230的(de)(de)厚度T(例如(ru),支(zhi)(zhi)撐構(gou)件(jian)230的(de)(de)最小(xiao)尺寸(cun))可(ke)以(yi)是(shi)80μm或(huo)更小(xiao),優選(xuan)60μm或(huo)更小(xiao),更優選(xuan)40μm或(huo)更小(xiao),但(dan)不限于(yu)(yu)此(ci)。
當支撐構件230的厚度是H并且主體部100的厚度是T時,H與T的比(H/T)可以是0.15或更小,例如,大約0.05至0.10。在支撐構件230的厚度在主體部100中所占的比例大于0.15時,設置在線圈部200的上部和下部的磁性材料的厚度會變得相對地薄,這樣會導致電感減小。此外,隨著支撐構件230的厚度增加,形成在支撐構件230中并延伸穿過支撐構件230的過孔234的厚度增加,使得堆疊在支撐構件230的背對的表面上多個線圈層211、212、221和222之間的電流路徑增加。其結果是,會減小電感和DC阻抗Rdc等。然(ran)而,為了保持剛度,支撐構件(jian)230的厚度過薄(bo)可能(neng)是不利的。

此外,參照圖6,線圈部200的右側引出截面可具有寬度從頂部朝向底部減小的錐形。盡管未在圖6中示出,但線圈部200的左側引出截面還可具有寬度從底部朝向頂部減小的錐形。這里,底部和頂部是關于圖5和圖6中的第三方向限定的。這是因為,除了支撐構件230以及絕緣層213和223的支持線圈層211、221、212和222的區域之外的區域可在制造線圈組件10A和支撐構件230的同時通過切邊工藝等選擇性地去除。在這種情況下,包括絕緣材料的絕緣層213和223可能在去除工藝中更多地朝向其拐角進行去除。線圈層211、221、212和222可基本不被影響。上述引出截面的形狀指的是通過下述方向形成主體部100:通過在支撐構件230上堆疊絕緣層213和223并分別在絕緣層213和223上穩定地形成第二線圈層212和222而形成在堆疊方向上的其匝(或繞組)數增加的線圈部200之后,通過利用磁性材料盡可能多的填充空間并通過切邊工藝等來形成。因此,可制造減小了諸如在線圈圖案之間出現短路等缺陷的風險、確保線圈的均勻性以及DC阻抗Rdc并實現纖薄的線圈組件。

第一線圈層211和221的線圈圖案導體的截面可具有小于1的高寬比(AR)(厚度h1與寬度w1的比(h1/w1))(其中,h1是與支撐構件230的使第一線圈層211和221設置在其上的背對的表面正交來測量的,w1是平行于所述背對的表面來測量的)。第二線圈層212和222的線圈圖案導體的截面可具有小于1的高寬比(AR)(厚度h2與寬度w2的比(h2/w2))(其中,h2是與支撐構件230的使第二線圈層212和222設置在其上的背對的表面正交來測量的,w2是平行于背對的表面來測量的)。也就是說,在根據另一示例的線圈組件10B中,線圈層211、212、221和222的線圈圖案導體可具有小于1的高寬比。例如,第一線圈層211和221的線圈圖案導體可具有大約160μm至190μm的寬度w1以及大約60μm至90μm的厚度h1,第二線圈層212和222的線圈圖案導體可具有大約160μm至190μm的寬度w2以及大約60μm至90μm的厚度h2。
在線圈層211、212、221和222的線圈圖案導體的高寬比小于1的情況下,在形成線圈圖案的工藝技術所允許的分布范圍內,可自由地調整線圈圖案的高度和寬度,使得線圈圖案的均勻性可以是良好的。此外,線圈圖案導體在寬度方向上較寬,使得線圈圖案的截面面積增加,從而可提供低DC阻抗Rdc特性。此(ci)外,由于無(wu)需強(qiang)制調整線圈(quan)匝或(huo)繞(rao)(rao)組之間(jian)(jian)間(jian)(jian)距,因此(ci),可(ke)減小諸(zhu)如線圈(quan)圖(tu)案之間(jian)(jian)短路等(deng)缺陷出現的(de)(de)(de)可(ke)能性。此(ci)外,由于線圈(quan)層211、212、221和222可(ke)具有相(xiang)同的(de)(de)(de)旋轉(zhuan)方向(xiang)(xiang)并(bing)可(ke)通(tong)過過孔214、224和234彼(bi)此(ci)電連接,因此(ci)可(ke)增加線圈(quan)在堆疊方向(xiang)(xiang)上的(de)(de)(de)匝(或(huo)繞(rao)(rao)組)數。這里,堆疊方向(xiang)(xiang)指的(de)(de)(de)是附圖(tu)中(zhong)的(de)(de)(de)第三(san)方向(xiang)(xiang)。
此外,由于線圈(quan)(quan)層(ceng)211、212、221和(he)(he)222的(de)(de)(de)(de)(de)線圈(quan)(quan)圖案(an)導體的(de)(de)(de)(de)(de)高寬比小于1,因此,線圈(quan)(quan)部的(de)(de)(de)(de)(de)厚度(與支(zhi)撐(cheng)構(gou)件(jian)230的(de)(de)(de)(de)(de)使(shi)線圈(quan)(quan)層(ceng)211和(he)(he)221設置(zhi)在(zai)其上(shang)的(de)(de)(de)(de)(de)背對(dui)表面(mian)(mian)正交進行測量的(de)(de)(de)(de)(de))可(ke)(ke)基本上(shang)較薄。這里(li),為了在(zai)線圈(quan)(quan)組(zu)(zu)件(jian)10B中具有足(zu)夠的(de)(de)(de)(de)(de)匝(或繞組(zu)(zu))數(shu),各(ge)個線圈(quan)(quan)層(ceng)211、221、212和(he)(he)222可(ke)(ke)形成為在(zai)水平方向(xiang)(xiang)(即在(zai)第(di)(di)一方向(xiang)(xiang)和(he)(he)/或第(di)(di)二(er)方向(xiang)(xiang))(例如,與支(zhi)撐(cheng)構(gou)件(jian)230的(de)(de)(de)(de)(de)使(shi)線圈(quan)(quan)層(ceng)211和(he)(he)221設置(zhi)在(zai)其上(shang)的(de)(de)(de)(de)(de)背對(dui)表面(mian)(mian)平行的(de)(de)(de)(de)(de)方向(xiang)(xiang))上(shang)盡可(ke)(ke)能(neng)多的(de)(de)(de)(de)(de)利用(yong)空間。也就是說,在(zai)豎直方向(xiang)(xiang)上(shang)堆疊的(de)(de)(de)(de)(de)第(di)(di)一線圈(quan)(quan)層(ceng)211和(he)(he)221以及第(di)(di)二(er)線圈(quan)(quan)層(ceng)212和(he)(he)222可(ke)(ke)具有重(zhong)疊的(de)(de)(de)(de)(de)區域。因此,可(ke)(ke)實(shi)現較薄的(de)(de)(de)(de)(de)并具有足(zu)夠的(de)(de)(de)(de)(de)線圈(quan)(quan)特性的(de)(de)(de)(de)(de)線圈(quan)(quan)組(zu)(zu)件(jian)。
第一線圈層211和221的線圈圖案導體可具有小于1的高寬比(AR)(厚度h1與寬度w1的比(h1/w1))。此外,第一線圈層211和221的線圈圖案可分別只包括單匝(或繞組)。這里,單匝(或繞組)可指示匝(或繞組)數等于或小于1。因此,可減小諸如線圈圖案之間短路等缺陷出現的風險,并可提供線圈均勻性和低DC阻抗Rdc。諸(zhu)如(ru)銅(Cu)、鋁(Al)、銀(yin)(Ag)、錫(Sn)、金(jin)(jin)(Au)、鎳(nie)(Ni)、鉛(Pd)或它們的(de)合金(jin)(jin)等的(de)導電金(jin)(jin)屬(shu)可用作第一線圈層211和221的(de)材料。
第二線圈層212和222的線圈圖案導體也可具有小于1的高寬比(AR)(厚度h2與寬度w2的比(h2/w2))。此外,第二線圈層212和222的線圈圖案可分別只包括單匝(或繞組)。這里,單匝(或繞組)可指示匝(或繞組)數等于或小于1。因此,可減小諸如線圈圖案之間短路等缺陷出現的風險,并可提供線圈均勻性和低DC阻抗Rdc。諸如銅(tong)(Cu)、鋁(Al)、銀(Ag)、錫(Sn)、金(Au)、鎳(nie)(Ni)、鉛(Pd)或它們的(de)合金等的(de)導電金屬(shu)可用作第(di)二線圈層212和222的(de)材料。

圖13是圖10的(de)線(xian)圈組件(jian)10B沿(yan)IV-IV′線(xian)截取的(de)示意性截面圖。
圖14是(shi)圖13的(de)線圈(quan)組件10B的(de)沿(yan)方向(xiang)b觀察的(de)主體部的(de)示意性截面圖。
參照圖(tu)(tu)13和圖(tu)(tu)14,還是(shi)在(zai)根據另一示例的(de)線(xian)(xian)圈組件10B中,線(xian)(xian)圈圖(tu)(tu)案的(de)引(yin)(yin)(yin)出以連接(jie)到(dao)外電極301和302的(de)引(yin)(yin)(yin)線(xian)(xian)端子可通過(guo)支(zhi)撐(cheng)(cheng)構(gou)件230和絕(jue)(jue)緣(yuan)層(ceng)213和223支(zhi)撐(cheng)(cheng)。因此,可穩定地形成線(xian)(xian)圈圖(tu)(tu)案的(de)引(yin)(yin)(yin)線(xian)(xian)端子,并可具有與(yu)外電極301和302的(de)良(liang)好的(de)連接(jie)力。同時(shi),盡(jin)管在(zai)圖(tu)(tu)14中省略了絕(jue)(jue)緣(yuan)膜215,但(dan)也可引(yin)(yin)(yin)出絕(jue)(jue)緣(yuan)膜215。可選地,絕(jue)(jue)緣(yuan)膜215也可基本上不保留在(zai)引(yin)(yin)(yin)出截面中。
此外,參照圖13和圖14,還是在根據另一示例的線圈組件10B中,線圈部200的右側引出截面可具有其寬度從引線的頂部朝向底部(例如,在從線圈層212朝向支撐構件230的方向上)減小的錐形。盡管在圖13和圖14中未示出,但線圈部200的左側引出截面還可具有其寬度從底部朝向頂部(例如,在從線圈層222朝向支撐構件230的方向上)減小的錐形。這里,頂部方向和底部方向是相對于圖14中示出的第三方向限定的。也就是說,根據前述,可制造減小了諸如線圈圖案之間出現短路等缺陷的風險、確保低DC阻抗Rdc和線圈(quan)的(de)均勻性(xing)并實現纖薄化的(de)線圈(quan)組件。

圖17A至(zhi)圖17F是示出用于形成圖13的(de)(de)線圈部的(de)(de)工(gong)藝(yi)步驟的(de)(de)示例的(de)(de)示意圖。
參照圖16A和圖17A,可制備(bei)支撐構件230。由于(yu)描(miao)述與(yu)上面關于(yu)圖8A和圖9A所描(miao)述的相同,因此將(jiang)省略其描(miao)述。
參照圖16B和圖17B,可(ke)(ke)分(fen)別在(zai)支撐(cheng)構件(jian)(jian)230的(de)(de)背對兩個表面(mian)(mian)(例如,上(shang)(shang)表面(mian)(mian)和下(xia)表面(mian)(mian))上(shang)(shang)形(xing)成(cheng)(cheng)第一(yi)線圈(quan)層211和221。如上(shang)(shang)所(suo)述(shu),第一(yi)線圈(quan)層211和221可(ke)(ke)形(xing)成(cheng)(cheng)為使得其線圈(quan)圖案(an)的(de)(de)高寬比小于(yu)1。在(zai)形(xing)成(cheng)(cheng)第一(yi)線圈(quan)層211和221時,可(ke)(ke)形(xing)成(cheng)(cheng)貫穿(chuan)支撐(cheng)構件(jian)(jian)230的(de)(de)過孔234,分(fen)別形(xing)成(cheng)(cheng)在(zai)支撐(cheng)構件(jian)(jian)230的(de)(de)表面(mian)(mian)上(shang)(shang)的(de)(de)第一(yi)線圈(quan)層211和221可(ke)(ke)通過過孔234彼(bi)此電連接。由于(yu)描(miao)述(shu)與上(shang)(shang)面(mian)(mian)關于(yu)圖8B和圖9B所(suo)描(miao)述(shu)的(de)(de)相同,因此將省略(lve)其描(miao)述(shu)。
參照(zhao)圖(tu)16C和(he)(he)17C,可在支撐構件230的兩個(ge)表面上分別(bie)堆疊絕(jue)緣層213和(he)(he)223,以分別(bie)覆蓋第一線圈層211和(he)(he)第二線圈層221。由于描述(shu)與上面關于圖(tu)8C和(he)(he)圖(tu)9C所(suo)描述(shu)的相同,因此將省略其描述(shu)。

參照圖16E和圖17E,可形成分別覆蓋第二(er)線(xian)圈層212和222的絕緣(yuan)膜215和225。由于描(miao)述與上面關(guan)于圖8E和圖9E所描(miao)述的相同,因此將(jiang)省略其描(miao)述。
參照圖(tu)16F和(he)圖(tu)17F,可移除(chu)線圈部200的(de)(de)選(xuan)擇(ze)(ze)(ze)區域(yu)(yu),所(suo)述(shu)選(xuan)擇(ze)(ze)(ze)區域(yu)(yu)包括除(chu)了(le)線圈部200的(de)(de)形成了(le)線圈層211、212、221和(he)222的(de)(de)區域(yu)(yu)之外的(de)(de)區域(yu)(yu)。可使用修邊(bian)(bian)法或(huo)切割法等選(xuan)擇(ze)(ze)(ze)性地去除(chu)該選(xuan)擇(ze)(ze)(ze)區域(yu)(yu)。修邊(bian)(bian)工(gong)藝或(huo)切割工(gong)藝的(de)(de)結果部分地體(ti)現在圖(tu)16F和(he)圖(tu)17F中,但(dan)未(wei)示出磁性材料(即,主(zhu)體(ti)部100)。由于描(miao)(miao)述(shu)與(yu)上面關于圖(tu)8F和(he)圖(tu)9F所(suo)描(miao)(miao)述(shu)的(de)(de)相同,因此將省略其(qi)描(miao)(miao)述(shu)。

線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)部200可包括在(zai)支撐構件230的(de)(de)一個表面上沿第(di)(di)(di)(di)三(san)方向(xiang)順序堆疊(die)的(de)(de)第(di)(di)(di)(di)一線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)241、第(di)(di)(di)(di)二(er)(er)(er)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)242、第(di)(di)(di)(di)三(san)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)243和第(di)(di)(di)(di)四線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)244。覆(fu)蓋(gai)(gai)第(di)(di)(di)(di)一線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)241的(de)(de)第(di)(di)(di)(di)一絕(jue)(jue)(jue)緣(yuan)層(ceng)(ceng)245、覆(fu)蓋(gai)(gai)第(di)(di)(di)(di)二(er)(er)(er)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)242的(de)(de)第(di)(di)(di)(di)二(er)(er)(er)絕(jue)(jue)(jue)緣(yuan)層(ceng)(ceng)246以(yi)及覆(fu)蓋(gai)(gai)第(di)(di)(di)(di)三(san)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)243的(de)(de)第(di)(di)(di)(di)三(san)絕(jue)(jue)(jue)緣(yuan)層(ceng)(ceng)247可分(fen)別(bie)設置在(zai)第(di)(di)(di)(di)一線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)241與(yu)第(di)(di)(di)(di)二(er)(er)(er)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)242之間(jian)(jian)、第(di)(di)(di)(di)二(er)(er)(er)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)242與(yu)第(di)(di)(di)(di)三(san)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)243之間(jian)(jian)以(yi)及第(di)(di)(di)(di)三(san)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)243與(yu)第(di)(di)(di)(di)四線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)244之間(jian)(jian)。第(di)(di)(di)(di)四線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)層(ceng)(ceng)244可被絕(jue)(jue)(jue)緣(yuan)膜248覆(fu)蓋(gai)(gai)。
第一線圈層241的線圈圖案導體可具有小于1的高寬比(AR)(厚度h1與寬度w1的比(h1/w1))(其中,h1是與支撐構件230的使第一線圈層241設置在其上的表面正交進行測量的,w1是平行于支撐構件230的表面進行測量的)。第二線圈層242的線圈圖案導體也可具有小于1的高寬比(AR)(厚度h2與寬度w2的比(h2/w2))(其中,h2是與支撐構件230的使第一線圈層241設置在其上的表面正交進行測量的,w2是平行于(yu)(yu)(yu)支撐構(gou)件230的(de)(de)表面進行測(ce)量的(de)(de))。類似地,第三線圈(quan)(quan)層243和第四線圈(quan)(quan)層244的(de)(de)線圈(quan)(quan)圖(tu)案導(dao)體也可具(ju)有(you)小于(yu)(yu)(yu)1的(de)(de)高寬比(厚度與寬度的(de)(de)比)。也就是,在根據另(ling)一示例的(de)(de)線圈(quan)(quan)組(zu)件10C中,全部線圈(quan)(quan)層241、242、243和244的(de)(de)線圈(quan)(quan)圖(tu)案導(dao)體可均具(ju)有(you)小于(yu)(yu)(yu)1的(de)(de)高寬比。此外(wai),線圈(quan)(quan)層241、242、243和244的(de)(de)線圈(quan)(quan)圖(tu)案可均包(bao)括單(dan)(dan)匝(za)或(huo)(huo)單(dan)(dan)個繞組(zu)。這里,單(dan)(dan)匝(za)或(huo)(huo)單(dan)(dan)個繞組(zu)可指示匝(za)(或(huo)(huo)繞組(zu))數等于(yu)(yu)(yu)或(huo)(huo)小于(yu)(yu)(yu)1。
因此,可在形成線圈圖案的工藝技術允許的分布范圍內自由地調整線圈圖案導體的高度和寬度,以使線圈圖案的均勻性可以是良好的,并且線圈圖案在寬度方向上較寬,以增大線圈部的截面面積,從而可實現低DC阻抗Rdc特性(xing)(xing)。此(ci)外,由于(yu)無需強制調整(zheng)線圈(quan)圖案匝或繞組之(zhi)間的(de)間隔,因(yin)此(ci),可(ke)減(jian)小將出現的(de)諸如線圈(quan)圖案之(zhi)間短路等缺陷的(de)可(ke)能性(xing)(xing)。此(ci)外,由于(yu)線圈(quan)層241、242、243和244可(ke)具有相同的(de)旋轉方向并(bing)可(ke)通過過孔261、262和263彼此(ci)電(dian)連接,因(yin)此(ci)可(ke)增(zeng)加線圈(quan)在(zai)堆疊(die)方向上的(de)匝數。這里,堆疊(die)方向指的(de)是附圖中的(de)第三方向。
此(ci)外(wai),由于(yu)線(xian)圈(quan)(quan)(quan)層241、242、243和244的線(xian)圈(quan)(quan)(quan)圖(tu)案導體(ti)的高寬比均小于(yu)1,因(yin)此(ci),線(xian)圈(quan)(quan)(quan)部(bu)的厚(hou)度可基本上是(shi)(shi)纖(xian)薄(bo)(bo)的。這里(li),為了具(ju)(ju)有足夠的匝(za)(或(huo)繞組)數,各個線(xian)圈(quan)(quan)(quan)層241、242、243和244可形成為在(zai)水平(ping)方向(xiang)(xiang)(即,第(di)一方向(xiang)(xiang)和/或(huo)第(di)二(er)方向(xiang)(xiang))上盡可能多的利用空(kong)間。也(ye)就是(shi)(shi)說,在(zai)沿豎(shu)直(zhi)方向(xiang)(xiang)堆疊的各個線(xian)圈(quan)(quan)(quan)層241、242、243和244之間可存在(zai)重疊的區域。因(yin)此(ci),可實現纖(xian)薄(bo)(bo)并(bing)具(ju)(ju)有足夠線(xian)圈(quan)(quan)(quan)特性的線(xian)圈(quan)(quan)(quan)組件。
在附(fu)圖中僅僅示(shi)出了(le)第(di)(di)(di)一線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)241、第(di)(di)(di)二線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)242、第(di)(di)(di)三線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)243和第(di)(di)(di)四線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)244,但還可(ke)在第(di)(di)(di)四線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)244上形成額(e)外的線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng),并且(qie)可(ke)在額(e)外的線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)與(yu)第(di)(di)(di)四線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)244之間設置其中形成了(le)過孔(kong)的絕緣層(ceng)(ceng),以便額(e)外的線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)和第(di)(di)(di)四線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)244可(ke)彼此電連接。在這種(zhong)情況下(xia),額(e)外的線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)可(ke)與(yu)第(di)(di)(di)一線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)241、第(di)(di)(di)二線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)242、第(di)(di)(di)三線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)243和第(di)(di)(di)四線(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)244具有(you)相同的成分。
此外,額外的(de)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)還可(ke)(ke)形(xing)成在第(di)(di)(di)(di)一(yi)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)241、第(di)(di)(di)(di)二(er)(er)(er)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)242、第(di)(di)(di)(di)三線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)243和(he)第(di)(di)(di)(di)四線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)244之(zhi)間,并且還可(ke)(ke)在額外的(de)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)與第(di)(di)(di)(di)一(yi)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)241、第(di)(di)(di)(di)二(er)(er)(er)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)242、第(di)(di)(di)(di)三線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)243和(he)第(di)(di)(di)(di)四線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)244之(zhi)間設置(zhi)其中形(xing)成了(le)過(guo)孔的(de)絕緣層(ceng)(ceng)(ceng)(ceng),以使額外的(de)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)與第(di)(di)(di)(di)一(yi)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)241、第(di)(di)(di)(di)二(er)(er)(er)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)242、第(di)(di)(di)(di)三線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)243和(he)第(di)(di)(di)(di)四線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)244可(ke)(ke)彼此電連接。在這種情(qing)況下,額外的(de)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)可(ke)(ke)與第(di)(di)(di)(di)一(yi)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)241、第(di)(di)(di)(di)二(er)(er)(er)線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)242、第(di)(di)(di)(di)三線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)243和(he)第(di)(di)(di)(di)四線(xian)(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)(quan)(quan)層(ceng)(ceng)(ceng)(ceng)244具有(you)相同的(de)成分(fen)。
同(tong)時(shi),在(zai)一些情況(kuang)下,相對于根據示例的(de)線(xian)(xian)圈組件10A,第(di)一線(xian)(xian)圈層241、第(di)二(er)線(xian)(xian)圈層242、第(di)三線(xian)(xian)圈層243和(he)第(di)四線(xian)(xian)圈層244中的(de)一個或更多(duo)個的(de)線(xian)(xian)圈圖案可(ke)(ke)具有如上所述的(de)大于1的(de)高寬比,并且可(ke)(ke)具有多(duo)匝。也就是說,線(xian)(xian)圈組件10A至10C的(de)高寬比或特性可(ke)(ke)彼此組合(he)。
圖(tu)21是(shi)圖(tu)18的線圈(quan)組(zu)件(jian)10C沿VI-VI′線截(jie)取的示(shi)意性(xing)截(jie)面圖(tu)。
圖22是圖21的線圈組件10C的沿方向c觀察的主(zhu)體部的示意性(xing)截面圖。
參(can)照(zhao)圖21和(he)(he)圖22,還是在(zai)根據(ju)另(ling)一示例的線(xian)(xian)圈(quan)(quan)組件10C中(zhong),線(xian)(xian)圈(quan)(quan)圖案的引出以連接到(dao)外(wai)電(dian)極301和(he)(he)302的引線(xian)(xian)端子可(ke)(ke)(ke)通過支撐構件230和(he)(he)絕(jue)(jue)緣(yuan)(yuan)(yuan)層(ceng)來支撐。因(yin)此,線(xian)(xian)圈(quan)(quan)圖案的引線(xian)(xian)端子可(ke)(ke)(ke)穩定(ding)地形(xing)成,并且可(ke)(ke)(ke)與外(wai)電(dian)極301和(he)(he)302具(ju)有良好(hao)的連接力。同時,盡管在(zai)圖22中(zhong)省略(lve)了絕(jue)(jue)緣(yuan)(yuan)(yuan)膜248,但(dan)還可(ke)(ke)(ke)引出絕(jue)(jue)緣(yuan)(yuan)(yuan)層(ceng)膜。可(ke)(ke)(ke)選地,絕(jue)(jue)緣(yuan)(yuan)(yuan)膜248也(ye)可(ke)(ke)(ke)基本上(shang)不保留在(zai)引出截面(mian)中(zhong)。
此外,參照圖21和22,還是在根據另一示例的線圈組件10C中,線圈部200的右側引出截面可具有其寬度從頂部朝向底部減小的錐形。也就是說,可制造減小了諸如線圈圖案之間出現短路等缺陷的風險、確保了低DC阻抗Rdc和線圈(quan)的(de)(de)均勻性(xing)并實現纖薄化的(de)(de)線圈(quan)組件。盡管(guan)未在(zai)圖21和圖22中(zhong)示出(chu),但在(zai)線圈(quan)部200的(de)(de)左側引出(chu)截面(mian)中(zhong),設置(zhi)在(zai)第(di)一(yi)線圈(quan)層241之(zhi)上的(de)(de)絕緣(yuan)層245、246和247以及設置(zhi)在(zai)第(di)一(yi)線圈(quan)層241之(zhi)下(xia)的(de)(de)支撐構件230可具(ju)有(you)近似錐形。這里(li),術語“在(zai)…之(zhi)上”和“在(zai)…之(zhi)下(xia)”是相對于圖21中(zhong)示出(chu)的(de)(de)第(di)三方向限(xian)定(ding)的(de)(de)。
圖23是(shi)示(shi)出制造圖18的線圈組(zu)件(jian)10C的工藝的示(shi)例的流程(cheng)圖。
參照圖(tu)(tu)23,作(zuo)為(wei)示例(li),可通過下面的步驟來制造根據另一示例(li)的線(xian)圈組(zu)件10C:使(shi)用支撐構件230形(xing)成(cheng)(cheng)多個(ge)線(xian)圈部(bu)200,通過在多個(ge)線(xian)圈部(bu)200上(shang)和下堆(dui)疊磁片(pian)形(xing)成(cheng)(cheng)多個(ge)主體部(bu)100,切割多個(ge)主體部(bu)100,在各個(ge)單獨的主體部(bu)100上(shang)形(xing)成(cheng)(cheng)電極(ji)部(bu)300。由于描(miao)述與如上(shang)所述(例(li)如,見(jian)圖(tu)(tu)7和圖(tu)(tu)15)相同,因此將(jiang)省略(lve)其描(miao)述。
圖24A至圖24G是示(shi)(shi)出用于形成圖19的線圈部的工(gong)藝步驟的示(shi)(shi)例的示(shi)(shi)意圖。
圖25A至圖25G是示出(chu)用于(yu)形成圖21的線圈部的工藝步驟的示例的示意圖。
參照圖24A和圖25A,可制備支撐構件230。由于描述與如上所述相同,因此將(jiang)省略其(qi)描述。
參照圖(tu)24B和(he)圖(tu)25B,可(ke)(ke)在支撐構件230的一(yi)(yi)個表面上形成第一(yi)(yi)線(xian)圈(quan)層(ceng)241。如上所述(shu),第一(yi)(yi)線(xian)圈(quan)層(ceng)241可(ke)(ke)形成為使得其(qi)(qi)線(xian)圈(quan)圖(tu)案的高寬比(bi)小(xiao)于1。由(you)于描述(shu)與如上所述(shu)相同,因此將(jiang)省略其(qi)(qi)描述(shu)。
參照圖24C和(he)圖25C,可在支(zhi)撐構件230的(de)一(yi)個表(biao)面(mian)上(shang)(shang)堆(dui)疊第一(yi)絕緣層(ceng)245,以覆蓋第一(yi)線(xian)圈(quan)(quan)層(ceng)241。由于描(miao)(miao)述(shu)(shu)(shu)與(yu)如(ru)上(shang)(shang)所述(shu)(shu)(shu)相(xiang)同(tong),因此將(jiang)省(sheng)略(lve)其描(miao)(miao)述(shu)(shu)(shu)。然后,可在第一(yi)絕緣層(ceng)245上(shang)(shang)形(xing)(xing)成第二(er)線(xian)圈(quan)(quan)層(ceng)242。如(ru)上(shang)(shang)所述(shu)(shu)(shu),第二(er)線(xian)圈(quan)(quan)層(ceng)242也可形(xing)(xing)成為使得其線(xian)圈(quan)(quan)圖案(an)的(de)高(gao)寬(kuan)比小于1。由于描(miao)(miao)述(shu)(shu)(shu)與(yu)如(ru)上(shang)(shang)所述(shu)(shu)(shu)相(xiang)同(tong),因此將(jiang)省(sheng)略(lve)其描(miao)(miao)述(shu)(shu)(shu)。
參(can)照圖24D和圖25D,可(ke)(ke)在(zai)第(di)一絕(jue)緣(yuan)層245上(shang)堆疊第(di)二(er)絕(jue)緣(yuan)層246,以覆蓋(gai)第(di)二(er)線圈(quan)(quan)層242。由于(yu)描(miao)述(shu)與如(ru)(ru)(ru)上(shang)所(suo)(suo)述(shu)相同,因(yin)此將(jiang)省(sheng)略(lve)其描(miao)述(shu)。然后,可(ke)(ke)在(zai)第(di)二(er)絕(jue)緣(yuan)層246上(shang)形(xing)成(cheng)第(di)三線圈(quan)(quan)層243。如(ru)(ru)(ru)上(shang)所(suo)(suo)述(shu),第(di)三線圈(quan)(quan)層243也可(ke)(ke)形(xing)成(cheng)為(wei)使(shi)得其線圈(quan)(quan)圖案的高寬(kuan)比小于(yu)1。由于(yu)描(miao)述(shu)與如(ru)(ru)(ru)上(shang)所(suo)(suo)述(shu)相同,因(yin)此將(jiang)省(sheng)略(lve)其描(miao)述(shu)。
參照(zhao)圖(tu)24E和圖(tu)25E,可(ke)(ke)在第(di)二絕(jue)緣(yuan)(yuan)層(ceng)246上堆疊第(di)三絕(jue)緣(yuan)(yuan)層(ceng)247,以覆(fu)蓋第(di)三線圈層(ceng)242。由(you)(you)于描(miao)述(shu)(shu)(shu)與(yu)如(ru)上所述(shu)(shu)(shu)相同,因(yin)此將(jiang)省略(lve)其(qi)(qi)(qi)描(miao)述(shu)(shu)(shu)。然后,可(ke)(ke)在第(di)三絕(jue)緣(yuan)(yuan)層(ceng)247上形成(cheng)第(di)四線圈層(ceng)244。如(ru)上所述(shu)(shu)(shu),第(di)四線圈層(ceng)244也可(ke)(ke)形成(cheng)為使得(de)其(qi)(qi)(qi)線圈圖(tu)案的高(gao)寬比小于1。由(you)(you)于描(miao)述(shu)(shu)(shu)與(yu)如(ru)上所述(shu)(shu)(shu)相同,因(yin)此將(jiang)省略(lve)其(qi)(qi)(qi)描(miao)述(shu)(shu)(shu)。
參照圖24F和圖25F,可形成覆(fu)蓋第(di)四線(xian)圈層244的絕緣膜248。由于描述與如上所(suo)述相同,因此(ci)將省略其描述。
參照圖(tu)(tu)24G和(he)圖(tu)(tu)25G,可選(xuan)擇性地(di)去除(chu)(chu)線圈部(bu)200的(de)(de)區(qu)域(yu)(yu),所(suo)(suo)述(shu)(shu)區(qu)域(yu)(yu)包(bao)括除(chu)(chu)了線圈部(bu)200的(de)(de)其中(zhong)形(xing)成(cheng)了線圈層241、242、243和(he)244的(de)(de)區(qu)域(yu)(yu)之外的(de)(de)區(qu)域(yu)(yu)。可使用修邊法(fa)或切(qie)割法(fa)等選(xuan)擇性地(di)去除(chu)(chu)所(suo)(suo)述(shu)(shu)區(qu)域(yu)(yu)。修邊工藝(yi)和(he)切(qie)割工藝(yi)的(de)(de)結(jie)果部(bu)分(fen)地(di)體現在(zai)圖(tu)(tu)24G和(he)圖(tu)(tu)25G中(zhong),但未(wei)示出磁性材料(即,主體部(bu)100)。由于描述(shu)(shu)與如上所(suo)(suo)述(shu)(shu)相(xiang)同,因此將(jiang)省略其描述(shu)(shu)。

參照圖(tu)(tu)26至圖(tu)(tu)28,根(gen)據另一(yi)示例的(de)(de)(de)(de)(de)(de)線(xian)(xian)(xian)圈(quan)組(zu)件10D也(ye)可具(ju)有使(shi)線(xian)(xian)(xian)圈(quan)部(bu)(bu)200設(she)(she)置(zhi)在(zai)(zai)(zai)包含磁性材料的(de)(de)(de)(de)(de)(de)主體部(bu)(bu)100中的(de)(de)(de)(de)(de)(de)結構(gou)(gou)。電(dian)連接到線(xian)(xian)(xian)圈(quan)部(bu)(bu)200的(de)(de)(de)(de)(de)(de)電(dian)極部(bu)(bu)300可設(she)(she)置(zhi)在(zai)(zai)(zai)主體部(bu)(bu)100的(de)(de)(de)(de)(de)(de)外表面上。線(xian)(xian)(xian)圈(quan)部(bu)(bu)200可包括支(zhi)(zhi)撐構(gou)(gou)件230以(yi)及設(she)(she)置(zhi)在(zai)(zai)(zai)支(zhi)(zhi)撐構(gou)(gou)件230的(de)(de)(de)(de)(de)(de)兩個表面上的(de)(de)(de)(de)(de)(de)多個線(xian)(xian)(xian)圈(quan)層211、212、221和(he)(he)(he)222。絕(jue)緣(yuan)層213和(he)(he)(he)223分(fen)別(bie)(bie)設(she)(she)置(zhi)在(zai)(zai)(zai)支(zhi)(zhi)撐構(gou)(gou)件230的(de)(de)(de)(de)(de)(de)各(ge)個表面上并(bing)分(fen)別(bie)(bie)覆蓋形(xing)成在(zai)(zai)(zai)內(nei)(nei)部(bu)(bu)的(de)(de)(de)(de)(de)(de)第(di)(di)一(yi)線(xian)(xian)(xian)圈(quan)層211和(he)(he)(he)221中的(de)(de)(de)(de)(de)(de)各(ge)個線(xian)(xian)(xian)圈(quan)層。絕(jue)緣(yuan)層213和(he)(he)(he)223可分(fen)別(bie)(bie)設(she)(she)置(zhi)在(zai)(zai)(zai)形(xing)成在(zai)(zai)(zai)上部(bu)(bu)的(de)(de)(de)(de)(de)(de)第(di)(di)一(yi)線(xian)(xian)(xian)圈(quan)層211與(yu)第(di)(di)二線(xian)(xian)(xian)圈(quan)層212之(zhi)(zhi)間(jian)以(yi)及形(xing)成在(zai)(zai)(zai)下(xia)部(bu)(bu)的(de)(de)(de)(de)(de)(de)第(di)(di)一(yi)線(xian)(xian)(xian)圈(quan)層221與(yu)第(di)(di)二線(xian)(xian)(xian)圈(quan)層222之(zhi)(zhi)間(jian)。在(zai)(zai)(zai)下(xia)文中,將(jiang)更詳細(xi)地描述(shu)(shu)(shu)根(gen)據另一(yi)示例的(de)(de)(de)(de)(de)(de)線(xian)(xian)(xian)圈(quan)組(zu)件10D的(de)(de)(de)(de)(de)(de)組(zu)件。然而,將(jiang)省略與(yu)上述(shu)(shu)(shu)內(nei)(nei)容(rong)重復的(de)(de)(de)(de)(de)(de)內(nei)(nei)容(rong),并(bing)將(jiang)主要描述(shu)(shu)(shu)與(yu)上述(shu)(shu)(shu)內(nei)(nei)容(rong)不同(tong)的(de)(de)(de)(de)(de)(de)內(nei)(nei)容(rong)。
第一線圈層211和221的線圈圖案可包括具有大于1的高寬比(AR)(厚度h1與寬度w1的比(h1/w1))的線圈圖案導體(或線圈圖案導體的一部分)以及具有小于1的高寬比(AR)(厚度h1與寬度w2的比(h1/w2))的線圈圖案導體(或線圈圖案導體的一部分)二者。第二線圈層212和222的大部分線圈圖案導體可具有大于1的高寬比(AR)(厚度h2與寬度w3的比(h2/w3))。例如,第一線圈層211和221的線圈圖案導體可具有大約30μm至50μm的寬度w1、大約90μm至150μm的寬度w2以及大約40μm至60μm的厚度h1。第二線圈層212和222的線圈圖案導體可具有大約40μm至60μm的寬度w3和大約40μm至70μm的厚度h2。
第(di)一(yi)線(xian)(xian)(xian)圈(quan)(quan)層(ceng)(ceng)(ceng)211和(he)(he)(he)221以及第(di)二線(xian)(xian)(xian)圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)222的(de)線(xian)(xian)(xian)圈(quan)(quan)圖案(an)可(ke)均(jun)具有多匝(za)或多個繞(rao)組。這里,由(you)于第(di)一(yi)線(xian)(xian)(xian)圈(quan)(quan)層(ceng)(ceng)(ceng)211和(he)(he)(he)221以及第(di)二線(xian)(xian)(xian)圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)222由(you)具有細線(xian)(xian)(xian)寬(kuan)的(de)線(xian)(xian)(xian)圈(quan)(quan)圖案(an)構成,因此(ci)(ci),第(di)一(yi)線(xian)(xian)(xian)圈(quan)(quan)層(ceng)(ceng)(ceng)211和(he)(he)(he)221以及第(di)二線(xian)(xian)(xian)圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)222的(de)線(xian)(xian)(xian)圈(quan)(quan)圖案(an)在(zai)水平方(fang)(fang)(fang)向(即,第(di)一(yi)方(fang)(fang)(fang)向和(he)(he)(he)/或第(di)二方(fang)(fang)(fang)向)上的(de)匝(za)(或繞(rao)組)數(shu)(shu)可(ke)基本(ben)上較(jiao)大。此(ci)(ci)外,由(you)于線(xian)(xian)(xian)圈(quan)(quan)層(ceng)(ceng)(ceng)211、212、221和(he)(he)(he)222可(ke)具有相同的(de)旋轉方(fang)(fang)(fang)向并可(ke)通(tong)過過孔214、224和(he)(he)(he)234彼此(ci)(ci)電連接,因此(ci)(ci),可(ke)增加(jia)線(xian)(xian)(xian)圈(quan)(quan)在(zai)堆疊(die)方(fang)(fang)(fang)向(即,第(di)三方(fang)(fang)(fang)向)上的(de)匝(za)數(shu)(shu)。線(xian)(xian)(xian)圈(quan)(quan)圖案(an)的(de)匝(za)數(shu)(shu)還可(ke)大于或小于圖26至(zhi)圖28中示出(chu)的(de)匝(za)數(shu)(shu)。
由(you)于(yu)線(xian)(xian)(xian)圈(quan)層(ceng)211、221、212和(he)222中的(de)大部(bu)分由(you)具有(you)(you)細線(xian)(xian)(xian)寬的(de)線(xian)(xian)(xian)圈(quan)圖(tu)案(an)形成(cheng),因此,線(xian)(xian)(xian)圈(quan)部(bu)的(de)厚度可較纖薄。這里,為了(le)具有(you)(you)足夠(gou)(gou)的(de)匝數,各個線(xian)(xian)(xian)圈(quan)層(ceng)211、221、212和(he)222可形成(cheng)為在水平(ping)方(fang)向(xiang)(即,第一(yi)方(fang)向(xiang)和(he)/或第二方(fang)向(xiang))上盡可能多的(de)利用空間。也就是說,在豎直方(fang)向(xiang)上堆疊的(de)第一(yi)線(xian)(xian)(xian)圈(quan)層(ceng)211和(he)221以及第二線(xian)(xian)(xian)圈(quan)層(ceng)212和(he)222可具有(you)(you)重(zhong)疊的(de)區域。因此,可實現纖薄并具有(you)(you)足夠(gou)(gou)線(xian)(xian)(xian)圈(quan)特性(例如,足夠(gou)(gou)的(de)電感)的(de)線(xian)(xian)(xian)圈(quan)組件。
設置在第一線圈層211和221的最外部(從線圈繞組的中心開始測量的)的線圈圖案的線寬w2可比設置在第一線圈層211和221的內部的線圈圖案的線寬w1寬。也就是說,設置在內部的線圈圖案可實現為具有相對細的線寬w1,以使設置在內部的線圈圖案的匝(或繞組)數較高,設置在外部的線圈圖案可實現為具有相對粗的線寬w2,以便可確保低的DC阻抗Rdc特性。此外,第一線圈層211和221的線圈圖案的相鄰匝(或繞組)之間的間距L1可比第二線圈層212和222的線圈圖案的相鄰匝之間的間距L2寬。也就是說,形成在內部的第一線圈層211和221的線圈圖案之間的間距L1可相對地寬,以減小諸如線圈圖案之間出現短路等缺陷的風險并使覆蓋第一線圈層211和221的絕緣層213和223平坦,從而可提高形成在外部的第二線圈層212和222的線圈的均勻性。此外,形成在外部的第二線圈層212和222的線圈圖案之間的間距L2可相對地窄,使(shi)得可總體上增(zeng)加線圈部200的(de)匝數(shu)。
雖然(ran)在(zai)附圖中(zhong)僅僅示出(chu)了第(di)(di)(di)一(yi)線圈(quan)(quan)層(ceng)(ceng)(ceng)211和(he)(he)(he)(he)221以(yi)及第(di)(di)(di)二(er)(er)線圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)(he)222,但還可(ke)在(zai)第(di)(di)(di)二(er)(er)線圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)(he)222上形(xing)(xing)成額(e)外(wai)的(de)(de)(de)(de)(de)線圈(quan)(quan)層(ceng)(ceng)(ceng),其中(zhong)形(xing)(xing)成了過孔(kong)的(de)(de)(de)(de)(de)絕(jue)緣層(ceng)(ceng)(ceng)可(ke)設(she)置在(zai)額(e)外(wai)的(de)(de)(de)(de)(de)線圈(quan)(quan)層(ceng)(ceng)(ceng)與第(di)(di)(di)二(er)(er)線圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)(he)222之(zhi)間(jian)(jian),以(yi)使額(e)外(wai)的(de)(de)(de)(de)(de)線圈(quan)(quan)層(ceng)(ceng)(ceng)與第(di)(di)(di)二(er)(er)線圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)(he)222可(ke)彼此(ci)電(dian)連接。此(ci)外(wai),額(e)外(wai)的(de)(de)(de)(de)(de)線圈(quan)(quan)層(ceng)(ceng)(ceng)還可(ke)形(xing)(xing)成在(zai)第(di)(di)(di)一(yi)線圈(quan)(quan)層(ceng)(ceng)(ceng)211和(he)(he)(he)(he)221與第(di)(di)(di)二(er)(er)線圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)(he)222之(zhi)間(jian)(jian),并且其中(zhong)形(xing)(xing)成了過孔(kong)的(de)(de)(de)(de)(de)絕(jue)緣層(ceng)(ceng)(ceng)可(ke)設(she)置在(zai)額(e)外(wai)的(de)(de)(de)(de)(de)線圈(quan)(quan)層(ceng)(ceng)(ceng)與第(di)(di)(di)一(yi)線圈(quan)(quan)層(ceng)(ceng)(ceng)211和(he)(he)(he)(he)221或第(di)(di)(di)二(er)(er)線圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)(he)222之(zhi)間(jian)(jian),使得額(e)外(wai)的(de)(de)(de)(de)(de)線圈(quan)(quan)層(ceng)(ceng)(ceng)與第(di)(di)(di)一(yi)線圈(quan)(quan)層(ceng)(ceng)(ceng)211和(he)(he)(he)(he)221或第(di)(di)(di)二(er)(er)線圈(quan)(quan)層(ceng)(ceng)(ceng)212和(he)(he)(he)(he)222可(ke)彼此(ci)電(dian)連接。

圖(tu)30是圖(tu)29的(de)線圈組件的(de)沿方向d觀察的(de)主體部的(de)示意性(xing)截面圖(tu)。
參(can)照(zhao)圖29和(he)圖30,還是在(zai)根(gen)據另一示例(li)的(de)線圈組件(jian)10D中,線圈圖案的(de)引出以連接(jie)到(dao)外電極301和(he)302的(de)引線端子可(ke)通(tong)過支撐(cheng)構件(jian)230和(he)絕(jue)緣(yuan)(yuan)(yuan)層(ceng)層(ceng)來(lai)支撐(cheng)。因此,線圈圖案的(de)引線端子可(ke)穩定地形成,并可(ke)與外電極301和(he)302具有良好的(de)連接(jie)力(li)。同時(shi),盡管在(zai)圖30中省略了絕(jue)緣(yuan)(yuan)(yuan)膜(mo)215,但還可(ke)引出絕(jue)緣(yuan)(yuan)(yuan)膜(mo)215。可(ke)選地,絕(jue)緣(yuan)(yuan)(yuan)膜(mo)215也可(ke)基本上不保留在(zai)引出截(jie)面中。
此外,參照圖29和圖30,還是在根據另一示例的線圈組件10D中,線圈部200的右側引出截面可具有其寬度從頂部朝向底部減小的錐形。盡管在圖29和圖30中未示出,但線圈部200的左側引出截面還可具有其寬度從底部朝向頂部減小的錐形。這里,頂部位置和底部位置是相對于圖29中示出的第三方向限定的。也就是說,可制造減小了諸如線圈圖案之間出現短路等缺陷的風險、確保線圈的均勻性和低DC阻抗Rdc并實(shi)現纖(xian)薄(bo)化的線圈組件(jian)。
