Njengoba izikrini zokubonisa ze-LED zisetshenziswa kabanzi, abantu banezidingo eziphakeme zekhwalithi yomkhiqizo nemiphumela yokubonisa. Enqubweni yokupakisha, ubuchwepheshe be-SMD bendabuko ngeke busakwazi ukufeza izidingo zesicelo sezimo ezithile. Ngokusekelwe kulokhu, abanye abakhiqizi bashintshe ithrekhi yokufaka futhi bakhethe ukuthumela i-COB nobunye ubuchwepheshe, kanti abanye abakhiqizi bakhethe ukuthuthukisa ubuchwepheshe be-SMD. Phakathi kwazo, ubuchwepheshe be-GOB bungubuchwepheshe obukhona ngemuva kokuthuthukiswa kwenqubo yokupakisha ye-SMD.
Ngakho-ke, nge-GOB technology, ingaholela ekubonisweni kwemikhiqizo ukufeza izinhlelo ezibanzi? Yikuphi ukuthambekela kokuthuthukiswa kwemakethe kwesikhathi esizayo? Ake sibheke!
Kusukela ukuthuthukiswa komkhakha wokubonisa we-LED, kufaka phakathi ukuboniswa kwe-COB, izinqubo ezahlukahlukene zokukhiqiza nezinqubo zokupakisha ziye zavela ngokulandelana, kusuka kwinqubo ye-COB Mountget (SMD), kuze kube sezingeni eliphezulu le-COB Packing Technology.
Uyini ubuchwepheshe bokupakisha we-COB?
Ukupakishwa kwe-COB kusho ukuthi linamathela ngokuqondile i-chip ku-PCB substrate ukwenza ukuxhumana kukagesi. Inhloso yayo eyinhloko ukuxazulula inkinga yokuhlanza ukushisa kwezikrini zokubonisa ze-LED. Uma kuqhathaniswa ne-plug-in eqondile ne-SMD, izici zayo zisindisa isikhala, ukusebenza okwenziwe lula, kanye nokuphathwa okusebenzayo okusebenzayo. Njengamanje, ukufakwa kwe-COB kusetshenziswa ikakhulukazi emikhiqizweni emincane ye-pitch.
Yiziphi izinzuzo zobuchwepheshe bokupakisha kwe-COB?
1. I-Ultra-Light and Thin: ngokwezidingo zangempela zamakhasimende, amabhodi we-PCB anobukhulu obungu-0,4
2. Ukulwa nokushayisana nokuphikiswa kwengcindezi Ingaphezulu lePhoyinti Lwesibani likhulela endaweni ephakanyisiwe, elibushelelezi futhi elinzima, elimelana nokushayisana nokugqoka.
I-3. I-angle enkulu yokubuka: Ukupakishwa kwe-COB kusetshenziswa ukuphuma okungajulile kokukhanya okukhanyayo, okune-angle yokubuka okungaphezu kwama-175 degrees, futhi kunomphumela ongcono wombala we-180.
4. Ikhono elinamandla lokuhlanza ukushisa Ngaphezu kwalokho, ukushuba kwe-foil ye-Copper yebhodi le-PCB kunezidingo eziqinile zenqubo, nenqubo yokucwila yegolide ngeke kubangele ukushiyeka okungathi sína. Ngakho-ke, kunamalambu ambalwa afile, anwebeka kakhulu impilo yesibani.
I-5. Ukugqoka okuvinjelwe futhi kulula ukuwahlanza: ingaphezulu lephuzu lesibani liyavela endaweni eyindilinga, ebushelelezi futhi evikelekile, imelana nokushayisana nokugqoka; Uma kunephuzu elibi, lingalungiswa iphuzu ngephuzu; Ngaphandle kwemaski, uthuli lungahlanzwa ngamanzi noma ngendwangu.
6. Zonke izici zesimo sezulu: zamukela ukwelashwa okuvikelwa kathathu, ngemiphumela emihle yokungena kwamanzi, umswakama, ukugcwala, uthuli, ugesi ophelele, oxidation, kanye ne-ultraviolet; Ihlangana nezimo zokusebenza zesimo sezulu sonke futhi isakwazi ukusetshenziswa ngokujwayelekile emvelweni umehluko wokushisa wendawo yokususa ama-degree angama-30 kuye kuma-80 degrees.
⚪Kuyini ubuchwepheshe bokupakisha i-GOB?
Ukupakishwa kwe-GOB kungubuchwepheshe bokupakisha owethulwe ukubhekana nezinkinga zokuvikelwa kobuhlalu be-LED. Isebenzisa izinto ezibonakalayo ezivelayo ukuze ihlanganise i-PCB substrate kanye neyunithi yokufaka i-LED ukwakha ukuvikelwa okusebenzayo. Kuyafana nokwengeza ungqimba lokuvikelwa phambi kwemodyuli yangempela ye-LED, ngaleyo ndlela kufinyelelwe imisebenzi ephakeme yokuvikela nokuthola ubufakazi, i-anti-sprapest, i-anti-braple, ukukhanya okuluhlaza okwesibhakabhaka, nokudlidliza.
Yiziphi izinzuzo zobuchwepheshe bokupakisha kwe-GOB?
1. Izinzuzo zenqubo ye-GOB: Kuyisikrini sokubonisa esivikela kakhulu esingafinyelela ukuvikela okuyisishiyagalombili: amanzi angenamanzi, ukungqubuzana, ukulimala okulwa nothuli, ukulimala okuluhlaza okwesibhakabhaka, kanye ne-anti-stal. Futhi ngeke kube nomphumela olimazayo ekushisweni kokushisa nokulahleka kokukhanya. Ukuhlolwa okunesikhathi eside kukhombisile ukuthi i-glue evikela ukuvikeleka kusiza ukuqeda ukushisa, kunciphisa izinga le-necrosis le-band ubuhlalu, futhi kwenza isikrini sizinzile, ngaleyo ndlela sinwebe impilo yenkonzo.
2. Ngokusebenza kwenqubo ye-GOB, amaphikiseli e-granular ebusweni bebhodi lokukhanya lokuqala aguqulwe abe yibhodi lokukhanya eliyisicaba, eqaphela ukuguqulwa komthombo wokukhanya okukhanyayo. Umkhiqizo ukhipha isibani ngokulinganayo, umphumela wokubonisa ucacile futhi ucace ngokwengeziwe, futhi i-angle yokubuka yomkhiqizo ithuthukiswa kakhulu (ngokuqondile futhi ibheke ngokuhlukile, ukunciphisa i-glare nokukhazimula, kanye nokunciphisa ukukhathala okubonakalayo.
⚪Uyini umehluko phakathi kukaCob noGob?
Umehluko phakathi kweCob ne-GOB ikakhulukazi kusesimweni. Yize iphakethe le-COB linendawo eyisicaba kanye nokuvikelwa okungcono kunephakethe lendabuko lendabuko, iphakethe le-GOB lengeza inqubo yokugcwaliswa kweglue ngaphezulu kwesikrini, okwenza ubuhlalu be-LED buzinzile, futhi bunciphise kakhulu ukuthi kungenzeka ukuthi bawe, futhi banqume ngokuqinile.
⚪Umuntu onezinzuzo, i-cob noma i-gob?
Akukho okujwayelekile okungcono, i-cob noma i-gob, ngoba kunezici eziningi zokwahlulela ukuthi inqubo yokupakisha ilungile yini noma cha. Isihluthulelo ukubona ukuthi yini esiyazisayo, noma ngabe ukusebenza kobuhlalu besibani se-LED noma ukuvikelwa, ngakho-ke ubuchwepheshe bokupaka ngamunye bunezinzuzo zalo futhi abanakwenziwa ngokujwayelekile.
Lapho empeleni sikhetha, noma sisebenzisa ukufakwa okufakwayo kwe-COB noma ukufakwa kwe-GOB kufanele kubhekwe ngokuhlanganiswa nezici eziphelele ezifana nendawo yethu yokufaka kanye nesikhathi sokusebenza, futhi kuhlobene nokulawulwa kwezindleko kanye nomphumela wokubonisa.
