Nka LED yerekana ecran ikoreshwa cyane, abantu bafite ibisabwa byinshi kubiranga ibicuruzwa no kwerekana ingaruka. Muburyo bwo gupakira, tekinoroji gakondo ya SMD ntishobora kongera kuzuza ibisabwa mubisabwa. Hashingiwe kuri ibi, ababikora bamwe bahinduye inzira yo gupakira bahitamo gukoresha COB nubundi buryo bwikoranabuhanga, mugihe ababikora bamwe bahisemo kunoza ikoranabuhanga rya SMD. Muri byo, tekinoroji ya GOB ni tekinoroji itera nyuma yo kunoza uburyo bwo gupakira SMD.
Noneho, hamwe na tekinoroji ya GOB, LED yerekana ibicuruzwa bishobora kugera kubikorwa byinshi? Ni ubuhe buryo iterambere ry'ejo hazaza rya GOB ryerekana? Reka turebe!
Kuva iterambere ryuruganda rwa LED rwerekana, harimo na COB yerekana, uburyo butandukanye bwo gukora no gupakira ibintu byagaragaye nyuma yikindi, uhereye kubikorwa byabanjirije kwinjiza (DIP), kugeza hejuru yimisozi (SMD), kugeza igihe COB yagaragaye. tekinoroji yo gupakira, hanyuma amaherezo yo kugaragara kwa tekinoroji yo gupakira.
TechnologyNi ubuhe buhanga bwo gupakira COB?
Gupakira COB bivuze ko ifata neza chip kuri substrate ya PCB kugirango ikore amashanyarazi. Intego nyamukuru yaryo ni ugukemura ikibazo cyo gukwirakwiza ubushyuhe bwa LED yerekana. Ugereranije no gucomeka neza na SMD, ibiranga ni ukubika umwanya, ibikorwa byo gupakira byoroshye, hamwe no gucunga neza ubushyuhe. Kugeza ubu, gupakira COB bikoreshwa cyane mubicuruzwa bito bito.
Ni izihe nyungu z'ikoranabuhanga ryo gupakira COB?
1. Ultra-yoroheje kandi yoroheje: Ukurikije ibyifuzo byukuri byabakiriya, imbaho za PCB zifite umubyimba wa 0.4-1.2mm zirashobora gukoreshwa kugirango ugabanye ibiro byibuze 1/3 cyibicuruzwa byumwimerere, bishobora kugabanya cyane imiterere, ubwikorezi nubwubatsi kubakiriya.
2. Kurwanya kugongana no kurwanya igitutu: Ibicuruzwa bya COB bikubiyemo mu buryo butaziguye chip ya LED mu mwanya uhuriweho n’ubuyobozi bwa PCB, hanyuma ukoreshe epoxy resin glue kugirango ukingire kandi ukire. Ubuso bwamatara yazamuye hejuru hejuru, yoroshye kandi ikomeye, idashobora kugongana no kwambara.
3. Inguni nini yo kureba: Gupakira COB ikoresha urumuri ruto rudasanzwe rwoherezwa mu kirere, hamwe n'inguni ireba hejuru ya dogere 175, hafi ya dogere 180, kandi ifite ingaruka nziza ya optique ikwirakwiza.
4. Ubushobozi bukomeye bwo gukwirakwiza ubushyuhe: Ibicuruzwa bya COB bikubiyemo itara ku kibaho cya PCB, hanyuma ugahita wohereza ubushyuhe bwa wick ukoresheje feri y'umuringa ku kibaho cya PCB. Byongeye kandi, ubunini bwumuringa wumuringa wubuyobozi bwa PCB bufite ibyangombwa bisabwa, kandi inzira yo kurohama zahabu ntishobora gutera urumuri rukomeye. Kubwibyo, hari amatara yapfuye, yongerera cyane ubuzima bwitara.
5. Kwirinda kwambara kandi byoroshye guhanagura: Ubuso bwurumuri rwamatara ni convex mubuso bwa serefegitura, yoroshye kandi ikomeye, idashobora kugongana no kwambara; niba hari ingingo mbi, irashobora gusanwa ingingo kumurongo; udafite mask, umukungugu urashobora guhanagurwa namazi cyangwa igitambaro.
6. Ibihe byose biranga ibihe byiza: Ifata uburyo bwo kurinda inshuro eshatu, hamwe ningaruka zidasanzwe ziterwa n’amazi, amazi, ruswa, umukungugu, umukungugu, amashanyarazi ahamye, okiside, na ultraviolet; yujuje ibihe byose byakazi bikora kandi birashobora gukoreshwa mubisanzwe mubushuhe butandukanye bwubushyuhe bwa dogere 30 kugeza kuri dogere 80.
⚪Ubuhanga bwo gupakira GOB ni ubuhe?
Gupakira GOB ni tekinoroji yo gupakira yatangijwe kugirango ikemure ibibazo byo kurinda amasaro ya LED. Ikoresha ibikoresho bigezweho bibonerana kugirango bikubiyemo PCB substrate hamwe na LED ipakira kugirango ikingire neza. Iringana no kongeramo urwego rwuburinzi imbere yumwimerere wa LED, bityo ukagera kubikorwa byokurinda cyane kandi ukagera ku ngaruka icumi zo gukingira zirimo izirinda amazi, izirinda amazi, izirinda ingaruka, zidashobora gukomeretsa, anti-static, umunyu utera umunyu , anti-okiside, urumuri rwubururu, na anti-vibrasiya.
Ni izihe nyungu za tekinoroji yo gupakira GOB?
1. Ibyiza bya GOB: Ni ecran ya LED ikingira cyane ishobora kugera ku burinzi umunani: butarinda amazi, butagira amazi, irwanya kugongana, irwanya ivumbi, irwanya ruswa, urumuri rwubururu, kurwanya umunyu, na anti- gihamye. Kandi ntabwo bizagira ingaruka mbi ku gukwirakwiza ubushyuhe no gutakaza umucyo. Igeragezwa ryigihe kirekire ryerekanye ko gukingira kole bifasha no gukwirakwiza ubushyuhe, bigabanya umuvuduko wa necrosis yamasaro yamatara, kandi bigatuma ecran ihagarara neza, bityo ikongerera igihe cya serivisi.
2. Binyuze mu gutunganya inzira ya GOB, pigiseli ya granulaire hejuru yumubaho wambere wumucyo yahinduwe muburyo rusange bwurumuri, bumenya guhinduka kuva kumurongo wumucyo ujya kumurabyo. Igicuruzwa gisohora urumuri ruringaniye, ingaruka zo kwerekana zirasobanutse kandi zisobanutse neza, kandi ibicuruzwa byo kureba ibicuruzwa byateye imbere cyane (haba mu buryo butambitse kandi buhagaritse bishobora kugera kuri 180 °), bikuraho burundu moiré, bigatera imbere cyane itandukaniro ryibicuruzwa, bigabanya urumuri no kumurika. , no kugabanya umunaniro ugaragara.
⚪Ni irihe tandukaniro riri hagati ya COB na GOB?
Itandukaniro riri hagati ya COB na GOB riri mubikorwa. Nubwo paki ya COB ifite ubuso buringaniye kandi irinzwe neza kuruta pake gakondo ya SMD, pake ya GOB yongeramo uburyo bwo kuzuza kole hejuru yubuso bwa ecran, bigatuma amasaro ya LED yamatara ahamye, bigabanya cyane amahirwe yo kugwa, kandi ifite ituze rikomeye.
HNi uwuhe ufite ibyiza, COB cyangwa GOB?
Nta gipimo cyiza cyiza, COB cyangwa GOB, kuko hariho ibintu byinshi byerekana niba inzira yo gupakira ari nziza cyangwa atari nziza. Urufunguzo ni ukureba icyo duha agaciro, cyaba ari imikorere yamasaro ya LED cyangwa kurinda, bityo buri tekinoroji yo gupakira ifite ibyiza byayo kandi ntishobora kuba rusange.
Mugihe duhisemo mubyukuri, niba dukoresha ibipfunyika bya COB cyangwa ibipfunyika bya GOB bigomba gutekerezwa hamwe nibintu byuzuye nkibidukikije byo kwishyiriraho hamwe nigihe cyo gukora, kandi ibi nabyo bifitanye isano no kugenzura ibiciro no kwerekana ingaruka.
