Njengoba izikrini zokubonisa ze-LED zisetshenziswa kabanzi, abantu banezidingo eziphakeme zekhwalithi yomkhiqizo nemiphumela yokubonisa. Enqubweni yokupakisha, ubuchwepheshe be-SMD bendabuko abusakwazi ukuhlangabezana nezidingo zohlelo lwezinye izimo. Ngokusekelwe kulokhu, abanye abakhiqizi bashintshe ithrekhi yokupakisha futhi bakhetha ukuhambisa i-COB nobunye ubuchwepheshe, kuyilapho abanye abakhiqizi bekhethe ukuthuthukisa ubuchwepheshe be-SMD. Phakathi kwazo, ubuchwepheshe be-GOB ubuchwepheshe obuphindaphindayo ngemuva kokuthuthukiswa kwenqubo yokupakisha ye-SMD.
Ngakho, ngobuchwepheshe be-GOB, ingabe imikhiqizo yokubonisa i-LED ingafinyelela izinhlelo zokusebenza ezibanzi? Yimuphi umkhuba ozoboniswa ukuthuthukiswa kwemakethe yesikhathi esizayo ye-GOB? Ake sibheke!
Kusukela ekuthuthukisweni kwemboni yokubonisa i-LED, okuhlanganisa nokuboniswa kwe-COB, izinqubo ezihlukahlukene zokukhiqiza nokupakisha ziye zavela ngokulandelana, kusukela ekufakweni okuqondile kwangaphambilini (i-DIP), kuya enqubweni ye-surface mount (SMD), ekuveleni kwe-COB. ubuchwepheshe bokupakisha, futhi ekugcineni ekuveleni kobuchwepheshe bokupakisha be-GOB.
⚪Buyini ubuchwepheshe bokupakisha be-COB?
Ukupakishwa kwe-COB kusho ukuthi kubambelela ngokuqondile i-chip ku-substrate ye-PCB ukuze yenze uxhumano lukagesi. Inhloso yayo eyinhloko ukuxazulula inkinga yokukhishwa kokushisa kwezikrini zokubonisa ze-LED. Uma kuqhathaniswa ne-plug-in eqondile kanye ne-SMD, izici zayo ukonga isikhala, imisebenzi yokupakisha eyenziwe lula, nokuphatha okushisayo okusebenzayo. Njengamanje, ukupakishwa kwe-COB kusetshenziswa kakhulu emikhiqizweni emincane.
Yiziphi izinzuzo zobuchwepheshe bokupakisha be-COB?
1. Ukukhanya okuphezulu nokuncane: Ngokwezidingo zangempela zamakhasimende, amabhodi e-PCB anogqinsi luka-0.4-1.2mm angasetshenziswa ukunciphisa isisindo okungenani sibe yi-1/3 yemikhiqizo yasekuqaleni, enganciphisa kakhulu izindleko zesakhiwo, ezokuthutha nezobunjiniyela zamakhasimende.
2. Ukumelana nokungqubuzana nokucindezela: Imikhiqizo ye-COB ihlanganisa ngokuqondile i-chip ye-LED endaweni eyi-concave yebhodi le-PCB, bese isebenzisa i-epoxy resin glue ukuhlanganisa nokwelapha. Ingaphezulu lephoyinti lesibani liphakanyiswa endaweni ephakanyisiwe, ebushelelezi futhi eqinile, imelana nokungqubuzana nokuguga.
3. I-engeli enkulu yokubuka: Ukupakishwa kwe-COB kusebenzisa ukukhanya okuyisiyingi okungashoni kahle, okune-engeli yokubuka enkulu kunamadigri angu-175, eduze namadigri angu-180, futhi kunomphumela ongcono wokukhanya ohlukanisayo wombala.
4. Ikhono eliqinile lokukhipha ukushisa: Imikhiqizo ye-COB ifaka isibani ebhodini le-PCB, futhi idlulise ngokushesha ukushisa kwentambo ngefoil yethusi ebhodini le-PCB. Ngaphezu kwalokho, ukujiya kocwecwe lwethusi lwebhodi le-PCB kunezidingo eziqinile zenqubo, futhi inqubo yokucwilisa igolide ngeke ibangele ukuncisha ukukhanya okukhulu. Ngakho-ke, kunezibani ezimbalwa ezifile, ezinweba kakhulu impilo yesibani.
5. Ingagugi futhi kulula ukuyihlanza: Ingaphezulu lephoyinti lesibani liqondile libe yindilinga, ebushelelezi futhi eqinile, imelana nokungqubuzana nokuguga; uma kukhona iphuzu elibi, lingalungiswa iphuzu ngephuzu; ngaphandle kwemaski, uthuli lungahlanzwa ngamanzi noma ngendwangu.
6. Izici ezinhle kakhulu zesimo sezulu sonke: Isebenzisa ukwelashwa kokuvikela kathathu, okunemiphumela evelele yokungangeni kwamanzi, umswakama, ukugqwala, uthuli, ugesi ongashintshi, i-oxidation, ne-ultraviolet; ihlangabezana nezimo zokusebenza zezulu laso sonke futhi isengasetshenziswa ngokujwayelekile endaweni ehlukile kwezinga lokushisa ephakathi kwamadigri angu-30 kuya ku-80.
⚪Buyini ubuchwepheshe bokupakisha be-GOB?
I-GOB packaging ubuchwepheshe bokupakisha okwethulwe ukubhekana nezinkinga zokuvikela ubuhlalu besibani se-LED. Isebenzisa izinto ezithuthukisiwe ezibonisa ngale ukuze ihlanganise i-substrate ye-PCB kanye neyunithi yokupakisha ye-LED ukuze kwakheke isivikelo esisebenzayo. Kulingana nokwengeza ungqimba lwesivikelo phambi kwemojula yokuqala ye-LED, ngaleyo ndlela kuzuza imisebenzi yokuvikela ephezulu futhi kuzuzwe imiphumela eyishumi yokuvikela ehlanganisa ukungangeni kwamanzi, umswakama-umswakama, i- impact-proof, i-bump-proof, i-anti-static, i-salt spray-proof , i-anti-oxidation, ukukhanya okuluhlaza okwesibhakabhaka, kanye ne-anti-vibration.
Yiziphi izinzuzo zobuchwepheshe bokupakisha be-GOB?
1. Izinzuzo zenqubo ye-GOB: Isikrini sokubonisa se-LED esivikela kakhulu esingafinyelela ukuvikeleka okuyisishiyagalombili: ukuvikeleka kwamanzi, umswakama, ukungqubuzana, ukuvikela uthuli, ukubola, ukukhanya okuluhlaza okwesibhakabhaka, ukunqanda usawoti, nokunqanda- i-static. Futhi ngeke kube nomthelela olimazayo ekulahlekeni kokushisa nokulahlekelwa ukukhanya. Ukuhlola okuqinile kwesikhathi eside kubonise ukuthi ukuvikela iglue kusiza ngisho nokuqeda ukushisa, kunciphisa izinga le-necrosis lobuhlalu besibani, futhi kwenza isikrini sizinze, ngaleyo ndlela andise impilo yesevisi.
2. Ngokucutshungulwa kwenqubo ye-GOB, amaphikseli ayimbudumbudu angaphezulu kwebhodi yokukhanya yasekuqaleni ashintshiwe aba yibhodi yokukhanya eyisicaba, eqaphela ukuguqulwa ukusuka emthonjeni wokukhanya kuya emthonjeni wokukhanya ongaphezulu. Umkhiqizo ukhipha ukukhanya ngokulinganayo, umphumela wokubonisa ucace kakhudlwana futhi ukhanye kakhudlwana, futhi i-engeli yokubuka yomkhiqizo ithuthukiswa kakhulu (kokubili okuvundlile nokuqondile kungafinyelela cishe ku-180°), iqede ngempumelelo i-moiré, ithuthukise kakhulu ukugqama komkhiqizo, inciphise ukuxhopha nokuxhopha. , nokunciphisa ukukhathala okubukwayo.
⚪Uyini umehluko phakathi kwe-COB ne-GOB?
Umehluko phakathi kwe-COB ne-GOB ikakhulukazi usenqubo. Nakuba iphakheji ye-COB inobuso obuyisicaba futhi isivikelo esingcono kunephakheji le-SMD lendabuko, iphakheji le-GOB lengeza inqubo yokugcwalisa iglue ebusweni besikrini, okwenza ubuhlalu besibani se-LED buqine, kunciphisa kakhulu amathuba okuwa, futhi inokuqina okuqinile.
⚪Iyiphi enezinzuzo, i-COB noma i-GOB?
Alikho izinga elingcono, i-COB noma i-GOB, ngoba kunezici eziningi zokwahlulela ukuthi inqubo yokupakisha yinhle noma cha. Isihluthulelo siwukubona lokho esikwazisayo, kungakhathaliseki ukuthi ukusebenza kahle kobuhlalu besibani se-LED noma isivikelo, ngakho-ke ubuchwepheshe bokupakisha bunezinzuzo zabo futhi abukwazi ukwenziwa jikelele.
Uma sikhetha ngempela, ukuthi sizosebenzisa ukupakisha kwe-COB noma ukupakisha kwe-GOB kufanele kucatshangelwe ngokuhambisana nezici ezibanzi njengendawo yethu yokufaka nesikhathi sokusebenza, futhi lokhu kuhlobene nokulawula izindleko nomthelela wokuboniswa.
