Me Ya Sa Bussing (Overlap Soldering) Ke Haifar da Tsagewar Ƙwayoyin Rana
Teburin Abubuwan Ciki
Amsa mai sauri: Fashewar rami na tsakiya da ke fitowa daga matakin bussing gazawa ce ta inji a haɗin tsakanin gefen tantanin da busbar. Abubuwa uku ne ke haddasa ta. Rata da aka tanada tsakanin tantanin da busbar ta yi ƙanƙanta, don haka ribbon ɗin ke ratsawa a kusurwa mai tsauri kuma yana matse gefen. An yi ribbon ɗin a kan bambancin tsayi wanda lamination daga baya ke daidaitawa, yana barin rarar ribbon wanda dole ya lanƙwasa a wani wuri. Ko kuma murfin ribbon ɗin ya narke ya zama zoben solder mai tasowa wanda ake matsewa cikin wafer. Duk ukun suna lodin gefen wafer mai kauri kusan 0.13 mm, kuma duk ukun yawanci suna bayyana ne kawai bayan lamination, a cikin electroluminescence.
Tsagewar rami na tsakiya na daga cikin mafi yawan lahani na kwalliya da layin samar da module ke haifarwa, kuma jerin abubuwan da za su iya haddasawa suna da yawa. Lalacewar jiyya, gilashi, encapsulant, kurakuran stringer da sigogin lamination duk suna da nasu alamomin. Wannan shafi ya takaita batun zuwa bangaren da ya fito daga bussing — matakin soldering na haɗuwa wanda ke haɗa ƙarshen string a kan busbar — kuma ya yi bayani kan hanyoyi uku da wannan mataki ke karya sel.
Abin da waɗannan ukun suka haɗa shi ne cewa babu ɗayansu da ya zama gazawar lantarki. Matsalolin geometry ne. Haɗin da ke tsakanin gefen sel da busbar wuri ne da wafer siriri, tsiri mai kauri da yawa na ribbon da haɗin solder suka haɗu, kuma inda tsiri da ke ƙarƙashin tashin hankali ke canza alkibla. Idan ka yi kuskuren wannan geometry da 'yan goma na millimita, wafer zai biya shi daga baya, a cikin matsi.
A ƙasa akwai tsarin kowane ɗaya daga cikin abubuwan haddasawa uku, abin da ke bambanta su da juna a kan layin, da abin da ya cancanci a auna kafin lamination maimakon bayan.
Haɗin da wannan shafi ya kunsa
Bussing shine inda ake manna ƙarshen igiyar da aka gama a kan busbar da ke tattara wutar lantarki kuma ta kai ta zuwa akwatin haɗin wuta. A kan igiyar TOPCon, ribbon ɗin yana barin gaban tantanin halitta kuma ana manna shi a bayan busbar, don haka haɗin yana tsaye a gefen tantanin halitta maimakon a tsakiyar saman tantanin halitta.
Na'urar tana kawo tantanin halitta da busbar zuwa wani mataki ɗaya yayin aikin. Wannan ba ya sa su zama kauri ɗaya, kuma bambancin ba ƙarami ba ne:
| Abu | Kaurin da aka saba |
|---|---|

| Ribbon na tsakiyar busbar | 0.35 mm zuwa 0.40 mm |
Don haka ribbon ɗin yana barin wafer na 0.13 mm, ya ketare rata, ya sauka a kan wani ɗigon da ya ninka kaurinsa kusan sau uku. Ribbon ɗin ne kaɗai memba da ke ratsa wannan matakin, kuma yana yin haka cikin tashin hankali. Inda ya taɓa gefen tantanin halitta, yana turawa. Wannan shine duk yanayin gazawar a cikin jumla ɗaya; dalilai uku da ke ƙasa su ne kawai hanyoyi uku na ƙara turawa.
Dalili na ɗaya: ratar da aka tanada tsakanin gefen tantanin halitta da busbar ta yi ƙanƙanta
Tazarar da ke tsakanin gefen tantanin halitta da busbar wani yanki ne na tsari, ba ma'aunin ƙayyadadden girma ba. Abubuwa da yawa na yau da kullum suna tura gefen tantanin halitta kusa da busbar fiye da yadda ya kamata. Matsalolin hangen nesa na CCD a kan injin busbar na iya yin hakan. Haka kuma kuskuren matsayi a kan wannan injin na iya yin hakan. Igiyar da tsawonta gaba ɗaya ya fita daga ma'auni kuma tana yin hakan, saboda tantanin halitta na ƙarshe yakan isa wani wuri dabam da inda na'urar ke tsammani.
Da zarar tazarar ta yi guntu, ribbon ɗin dole ne ya yi irin wannan hawan a kan ɗan gajeren tafiya, don haka kusurwar da ke tsakanin ribbon ɗin da gefen wafer ɗin takan ƙara tsananta. Ɗauki ƙarfin ribbon ɗin a matsayin kusan akai-akai sannan ka raba shi zuwa sassa biyu a wurin da ribbon ɗin ya bar tantanin halitta:
- F1 yana aiki a cikin jirgin wafer ɗin, yana jan ribbon ɗin zuwa ga busbar.
- F2 yana aiki daidai da wafer ɗin, yana danna ribbon ɗin ƙasa a kan gefen tantanin halitta.
Tsallakewa mai zurfi yana motsa tashin hankali daga F1 zuwa F2. Jan hankali a kwance yana raguwa, matsin ƙasa yana ƙaruwa, kuma gefen shine inda wannan matsin ya isa. Silicon yana da karyewa, wafer ɗin yana da siriri, kuma gefen wani fili ne mai 'yanci ba tare da wani abu a kusa da shi don yada nauyin ba. Tsagewa yana farawa daga gefen kuma yana gudu zuwa ciki. A kan ingantaccen module yana bayyana a matsayin layi mai duhu ko faci mai duhu a cikin EL.
Wannan sanadin shine mafi sauƙi daga cikin ukun don hanawa kuma mafi wuya a gani, saboda haɗin da ya yi nesa da 0.2 mm yana kama da daidai. Kulawa ita ce jeri da kanta: daidaita hangen nesa, iyawar maimaita jeri na kan bussing, da haƙurin tsayin igiyar da ke zuwa daga stringer.
Sanadi na biyu: an yi ribbon ɗin a kan matakin da lamination ke cirewa
Sanadi na biyu yana farawa haka, tare da bambancin tsayi tsakanin tantanin halitta da busbar a tashar bussing, amma sakamakon ya bambanta. A nan bambancin ya yi girma sosai har ribbon ɗin, da zarar an sayar da shi, yana riƙe da mataki a cikin siffarsa. An yi haɗin, an gyara ribbon ɗin, kuma tsayin ribbon ɗin a cikin wannan haɗin yanzu adadi ne da ba ya canzawa.
Lamination sannan yana yin abin da lamination yake yi: yana matse haɗin ƙasa. Filayen biyu suna zuwa daidai, kuma hanyar da ribbon ɗin zai ratsa tsakanin su tana yin guntu. Ribbon ɗin, duk da haka, ya riga ya kai tsawon da yake da shi, kuma ba zai iya guntuwa. Ragin dole ya tafi wani wuri, don haka ribbon ɗin yana lanƙwasa — kuma lanƙwasawar tana kan gefen tantanin.
Sakamakon shine lahani ɗaya da sanadi na ɗaya, tare da wata alama daban: yakan bayyana a rukuni maimakon tantanin da ya keɓe, domin matakin mallakar saitin ne ba na haɗin gwiwa ɗaya ba. Hakanan shine dalilin da yasa haɗin gwiwa zai iya wuce dubawa a tashar bussing kuma har yanzu ya haifar da tsagewa a matsi. Daidaiton saman a bussing shine wurin sarrafawa, ba kamannin haɗin gwiwa ba.
Sanadi na uku: murfin ya narke ya zama zobe mai ɗagawa
Sanadi na uku shine mafi ƙarancin, shine mafi koyarwa, kuma shine kaɗai wanda ke farawa a matsayin shawarar siye. Ya bayyana a cikin lamarin tushe a matsayin layi mai tsayin daka na tsagewar tsakiyar rami bayan lamination. Masu lamination da yawa suna samar da lahani ɗaya kuma injin bussing shine abu ɗaya da aka gyara a hoton, wanda shine abin da ya nuna binciken zuwa matakin bussing.
Abin da ke faruwa a can: tantanin da busbar ɗin suna da ɗan bambancin tsayi, kuma a yankin cokali mai yatsu, inda busbar ɗin ya rabu zuwa ga jagororin, babu busbar a ƙarƙashin ribbon ɗin da za a yi walda da shi. Ribbon ɗin ya rabu da wafer ɗin. Zafin narkewar gami da ya narke murfin ribbon ɗin, wanda ya ja kansa ya zama ƙulli a kewayen ribbon ɗin kuma ya daskare a matsayin zobe mai ɗagawa. A ƙarƙashin matsin lamination wannan zoben ya yi aiki a matsayin wuri mai tauri a saman wafer mai rauni, kuma ya fashe shi.
Dalilin da zoben suka bayyana a rukuni shi ne abin da ya cancanci tunawa.
