Ngena kuwo nawuphi na umzi-mveliso wephaneli yelanga. I-laminator isebenza kwi-150 ° C, icinezela i-EVA encapsulant phakathi kweglasi kunye ne-backsheet. Ngaphandle kweteyiphu ye-PTFE, i-EVA etyhidiweyo iya kuphola kwi-platen yokufudumeza kunye ne-silicone diaphragm, idala ubumdaka obuncangathi obuyonakalisa indawo yolawulo elandelayo kwaye ithatha iiyure ukuyikhuhla.
Nantso ukusetyenziswa okucacileyo. Kodwa kukho enye engabonakaliyo: ngaphakathi kwimodyuli egqityiweyo, Iteyiphu ye-PTFE isonga iibhasi apho badlula khona kwi-backsheet evulekileyo, ukuthintela ukuqhuma kwe-voltage ephezulu. Kwiinkqubo ze-1500V (eziqhelekileyo namhlanje), le ngqungquthela iyimfuneko yokhuseleko.
I-Aokai PTFE ibonelela ngeentlobo zombini – inkqubo yezinto ezisetyenziswayo kunye nokugqunyelelwa okusisigxina – ngeemfuno ezahlukileyo ezicacileyo. Masihambe apho i-PTFE tape iya khona kwimodyuli ye-PV, kwaye zeziphi iipropati ezibalulekileyo kwindawo nganye.

Ukukhuselwa komda weLaminator-Ukulwa nokuNcama kwe-EVA
Ngexesha le-lamination (145-165 ° C, 15-25 imizuzu), i-EVA encapsulant iyanyibilika kwaye ihamba. Abanye ngokungenakuthintelwa bacudisa ngaphandle ukuya emaphethelweni. Ukuba idibanisa ipleyiti yokufudumeza yesinyithi okanye i-silicone vacuum diaphragm, idibanisa ngokusisigxina.
Indlela i-PTFE tape isombulula ngayo
Iteyiphu ye-PTFE esetyenziswa kule miphezulu yenza i-EVA enyangisiweyo ixobule kwisiqwenga esinye. Abaqhubi basula i-tape ngelaphu phakathi kwemijikelezo, kwaye isicelo esisodwa sithatha iiveki.
Yintoni onokuyijonga kwi-tape ye-lamination
I-Substrate: I-Fiberglass-iqiniswe i-PTFE (0.13-0.18mm). Ifilimu ye-PTFE ecocekileyo ikrazula ngokulula kakhulu xa ukhuhla i-EVA enyangisiweyo.
I-Adhesive: Silicone PSA kuphela. I-Acrylic iyathambisa kwaye ikhuphe kwi-150 ° C, ingcolise i-laminator.
Ukuncipha kobushushu: Ayinamsebenzi kwiqondo lobushushu le-lamination - i-tape ayifanele igobe okanye iveze imiphetho yesinyithi.
Ukukhupha okuphantsi: Ngaphantsi kwe-vacuum lamination, i-volatiles evela kwi-adhesive esemgangathweni esemgangathweni inokubangela amaqamza kwimodyuli. Ilahleko yobunzima obupheleleyo <1% yinjongo elungileyo.
Ukusuka kumgangatho wefektri : Omnye umenzi wemodyuli ubike ukunciphisa ixesha lokucoca i-laminator ukusuka kwimizuzu ye-45 ngokutshintsha ukuya kwimizuzu emi-5 emva kokutshintshela kwi-premium fiberglass-backed PTFE tape kunye ne-high-crosslink silicone adhesive. Iteyiphu ixabisa ngaphezulu kwasekuqaleni kodwa yazihlawulela kwiiveki ezimbini.
I-Insulation ye-Busbar esisigxina - ukuthembeka kweminyaka engama-25 kuyafuneka
Ngaphakathi kwimodyuli egqityiweyo, iibhasi (i-ribbon yobhedu enetinki) zidibanisa iintambo zeseli kwibhokisi ye-junction. Apho badlula khona kwisithuba esikwi-backsheet, okanye ukugoba kufutshane nesakhelo se-aluminiyam, ukukhutshwa kwe-insulation kungaqina. Iteyiphu ye-PTFE isonga ngebhasi kwezi ndawo.
Le tape ayityiwa . Kufuneka igcine ubomi bewaranti yemodyuli - iminyaka engama-25 okanye ngaphezulu - ngaphandle, phantsi kwe-UV, ukukhwela ibhayisekile kobushushu (-40 ° C ukuya + 85 ° C), kunye nobushushu obumanzi (85 ° C / 85% RH).
Iimpawu ezibalulekileyo zetape yokugquma ibhasi
Imfuneko |
Isizathu Sokuba Kubalulekile |
Amandla eDielectric ≥8kV (0.08mm) / ≥10kV (0.13mm) |
Kufuneka ihlale iphezulu emva kwe-1000-2000h ukuguga kobushushu obumanzi (IEC 61215) |
Ukucutheka kukonke ≤1% (ngokufanelekileyo ≤0.5%) |
Ikhusela uxinzelelo lwe-backsheet okanye i-busbar eveziweyo emva kwemijikelo ye-thermal |
I-CTI 600V (PTFE yendalo) |
Akukho mikhondo yekhabhoni eqhubayo phantsi kongcoliseko lomphezulu |
Ukumelana ne-UV (yemodyuli yeglasi ephindwe kabini) |
Ukuncamathelisa akufuneki kuthotywe ukusuka ekungeneni kokukhanya |
I-Silicone PSA, hayi i-acrylic |
I-Acrylic hydrolyzes phantsi kobushushu obumanzi, ukulahlekelwa ukunamathela kunye nokukhupha i-acetic acid |
UL94 V-0 okanye VTM-0 |
Ifunelwa isiqinisekiso sokhuseleko (UL 510) |
Inqaku lemizi-mveliso: Abanye abenzi beemodyuli ezixabisa kancinci basebenzisa iteyiphu ye-polyimide (Kapton) ukugquma ibhasbha. Ngelixa i-polyimide inamandla aphezulu e-dielectric, ifunxa ukufuma kwaye inokuphulukana neempawu zokugquma kubushushu obufumileyo. I-PTFE ihlala izinzile. Kwiimodyuli ze-1500V, i-PTFE iya icaciswa ngakumbi.
Ibhokisi yeJunction Fixation & Insulation
Ngaphakathi kwebhokisi ye-junction, imisila yebhasi ye-solder kwi-diode / i-terminal block. Iteyiphu ye-PTFE isebenza iindima ezimbini: ukugquma apho ii-conductors ezingenanto zikufutshane, kunye nokulungiswa koomatshini - ukucofa iingcingo phantsi kuthintela ukudinwa kokungcangcazela.
Kutheni ukubuyiswa komlilo kunyanzelekile
Ibhokisi yesiphambuka ngumthombo womlilo onokubakho ukuba i-bypass diode iyasilela. Iteyiphu ye-PTFE apha kufuneka ibenokalisho lwe-UL94 V-0. Kwakhona, kufuneka iphathe ukushisa okuqhubekayo kwi-diode (ngokuqhelekileyo i-85-90 ° C) ngaphandle kwezilwanyana ezinwabuzelayo okanye ukulahlekelwa ukunamathela.
Iteyiphu yefilimu ye-PTFE ebhityileyo (0.05-0.08mm) isebenza kakuhle apha kuba ithandela ngokuqinileyo kwiingcingo kunye neetheminali.
I-Soldering Mask kunye noKhuseleko lweThutyana
Ngexesha le-tabbing kunye nentambo, i-flux kunye ne-solder etyhidiweyo inokutshiza kwiiseli, ibangele iziphene zokuthambisa okanye i-micro-cracks. Iteyiphu ye-PTFE igquma okwexeshana imiphetho yeseli okanye iindawo ezingathengiswanga.
Iimfuno ezahlukeneyo - akukho ukuguga kwexesha elide elifunekayo
Ukuxhathisa nje ubushushu obuphezulu (ukukhanya okufutshane kwi-300 ° C + ukusuka kwintsimbi ye-soldering), indawo egxotha i-solder, kunye ne-zero intsalela emva kokuxobula. Nkqu ne-adhesive ye-acrylic inokusebenza apha kuba ukuvezwa kukufutshane kwaye amaqondo obushushu aphezulu - kodwa i-silicone ikhuselekile kubo nabuphi na ubushushu obungaphezulu kwe-200°C.

Izinto zokuThatha zokugqibela
Iindidi zeteyiphu ezimbini ezahlukeneyo ze-PTFE zisebenzela ishishini le-PV.
Ukusetyenziswa kwenkqubo (ukukhusela i-laminator, imaski ye-solder): gxininisa kwi-non-stick, ukucocwa lula, kunye nokumelana nokushisa kwexesha elifutshane.
Ukugquma kwangaphakathi okusisigxina (i-busbar wrap, ibhokisi ye-junction): imfuno epheleleyo ye-IEC 61215 isiqinisekiso - ubushushu obumanzi, ibhayisikili ye-thermal, i-UV, kunye ne-shrinkage <1%.
I-Silicone PSA ayinakuxoxisana kuyo nayiphi na iteyipu eya kubona i-150 ° C + okanye iminyaka engama-25 yobomi bangaphandle.
I-Aokai PTFE ibonelela ngeendidi zombini ngamaxwebhu ovavanyo. Ukugquma ibhasbar, sibonelela ngobushushu obufumileyo idatha yamandla edielectric endala. Kwiteyiphu ye-lamination, sinikezela ngohlalutyo lwe-outgassing kunye nezalathiso zobomi basendle.
