Mu buhanga bugezweho bwa elegitoronike, LED yerekana ikoreshwa cyane mubyapa bya digitale, inyuma yicyiciro, imitako yo mu nzu nizindi nzego kubera umucyo mwinshi, ibisobanuro bihanitse, ubuzima burebure nibindi byiza. Mubikorwa byo gukora LED yerekana, tekinoroji ya encapsulation niyo sano nyamukuru. Muri byo, tekinoroji ya SMD hamwe na tekinoroji ya COB ni ibintu bibiri byingenzi. None, ni irihe tandukaniro riri hagati yabo? Iyi ngingo izaguha isesengura ryimbitse.
1.ni ubuhe buryo bwo gupakira SMD, ihame ryo gupakira SMD
Porogaramu ya SMD, izina ryuzuye rya Surface Yashizwe Igikoresho (Igikoresho cyububiko bwa Surface), ni ubwoko bwibikoresho bya elegitoronike bisudira mu buryo butaziguye ku kibaho cyacapwe (PCB) tekinoroji yo gupakira. Iri koranabuhanga rinyuze mumashini ishyira neza, chip ya LED ikubiyemo (mubisanzwe irimo diode itanga urumuri rwa LED hamwe nibice bikenerwa byumuzunguruko) yashyizwe neza kuri padi ya PCB, hanyuma ikoresheje kugurisha ibintu hamwe nubundi buryo bwo kumenya amashanyarazi.Gupakira SMD tekinoroji ituma ibikoresho bya elegitoronike bito, byoroheje muburemere, kandi bifasha mugushushanya ibicuruzwa bya elegitoroniki byoroshye kandi byoroshye.
2.Ibyiza n'ibibi bya tekinoroji yo gupakira SMD
2.1 Ibyiza byo gupakira ibikoresho bya SMD
(1)ubunini buto, uburemere bworoshye:Ibikoresho bipakira SMD ni bito mubunini, byoroshye guhuza ubucucike bwinshi, bifasha mugushushanya ibicuruzwa bya elegitoroniki ntoya kandi yoroshye.
(2)ibyiza biranga inshuro nyinshi:Amagambo magufi n'inzira ngufi zifasha kugabanya inductance hamwe no guhangana, kunoza imikorere-yumurongo mwinshi.
(3)Byoroshye kubyara umusaruro:bikwiranye no gukora imashini ishyira mu buryo bwikora, kunoza umusaruro no gutezimbere ubuziranenge.
(4)Imikorere myiza yubushyuhe:guhuza bitaziguye na PCB hejuru, bifasha ubushyuhe.
2.2 Ingaruka za tekinoroji ya SMD
(1)kubitaho bigoye: nubwo uburyo bwo kwishyiriraho hejuru byoroha gusana no gusimbuza ibice, ariko mugihe cyo guhuza kwinshi, gusimbuza ibice byihariye bishobora kuba bitoroshye.
(2)Ahantu ho gukwirakwiza ubushyuhe:cyane binyuze muri padi na gel gusohora ubushyuhe, umwanya muremure akazi kenshi gashobora kuganisha ku bushyuhe, bigira ingaruka mubuzima bwa serivisi.
3.ni ubuhe buryo bwo gupakira COB, ihame ryo gupakira COB
Porogaramu ya COB, izwi nka Chip on Board (Chip on Board pack), ni chip yambaye ubusa isudira muburyo bwa tekinoroji yo gupakira PCB. Inzira yihariye ni chip yambaye ubusa (umubiri wa chip hamwe na I / O muri terefone hejuru) hamwe na kashe ya hydratif cyangwa yumuriro ihujwe na PCB, hanyuma ikanyura mu nsinga (nka aluminium cyangwa zahabu) muri ultrasonic, munsi yibikorwa y'umuvuduko w'ubushyuhe, imashini ya chip ya I / O hamwe na padi ya PCB birahujwe, hanyuma bigashyirwaho kashe hamwe no kurinda resin. Iyi encapsulation ikuraho amatara gakondo ya LED yamashanyarazi, kugirango pake irusheho kuba myiza.
4.Ibyiza nibibi bya tekinoroji yo gupakira COB
4.1 Ibyiza byo gupakira COB
(1) paki yuzuye, ingano nto:gukuraho pin yo hepfo, kugirango ugere ku bunini bwa paki.
(2) imikorere isumba izindi:insinga ya zahabu ihuza chip nu kibaho cyumuzunguruko, intera yohereza ibimenyetso ni ngufi, kugabanya inzira nyabagendwa na inductance nibindi bibazo kugirango tunoze imikorere.
(3) Gukwirakwiza ubushyuhe bwiza:chip irasudizwa neza muri PCB, kandi ubushyuhe bukwirakwizwa mu kibaho cyose cya PCB, kandi ubushyuhe bukagabanuka.
(4) Imikorere ikomeye yo kurinda:igishushanyo gifunze neza, hamwe n’amazi adashobora gukoreshwa n’amazi, atagira amazi, yangiza umukungugu, anti-static nindi mirimo yo gukingira.
(5) uburambe bwiza bwo kubona:nkubuso bwumucyo utanga isoko, imikorere yibara irarushijeho kuba nziza, birambuye birambuye gutunganya, bikwiranye nigihe kirekire cyo kureba.
4.2 Ikoreshwa rya tekinoroji ya COB
(1) ingorane zo kubungabunga:chip na PCB gusudira mu buryo butaziguye, ntibishobora gusenywa ukundi cyangwa gusimbuza chip, amafaranga yo kubungabunga ni menshi.
(2) ibisabwa bikenewe mu musaruro:uburyo bwo gupakira ibisabwa kubidukikije ni hejuru cyane, ntibwemerera umukungugu, amashanyarazi ahamye nibindi bintu byangiza.
5. Itandukaniro riri hagati yubuhanga bwo gupakira SMD nubuhanga bwo gupakira COB
Ikoranabuhanga rya SMD hamwe na tekinoroji ya COB murwego rwo kwerekana LED buriwese afite umwihariko wihariye, itandukaniro riri hagati yaryo rigaragarira cyane cyane muri encapsulation, ingano nuburemere, imikorere yo gukwirakwiza ubushyuhe, koroshya kubungabunga no gukoresha ibintu. Ibikurikira nigereranya rirambuye nisesengura:
5.1 Uburyo bwo gupakira
TechnologySMD yo gupakira ibikoresho: izina ryuzuye ni Surface Mounted Device, ni tekinoroji yo gupakira igurisha chip yapakiye LED hejuru yububiko bwumuzingo wacapwe (PCB) binyuze mumashini yuzuye neza. Ubu buryo busaba chip ya LED gupakirwa mbere kugirango ikore ibice byigenga hanyuma igashyirwa kuri PCB.
Technology tekinoroji yo gupakira: COB: izina ryuzuye ni Chip on Board, ni tekinoroji yo gupakira igurisha byimazeyo chip yambaye ubusa kuri PCB. Ikuraho intambwe zo gupakira kumasaro ya LED yamatara gakondo, ihuza chip yambaye ubusa na PCB hamwe na kole ya transive cyangwa yumuriro, kandi ikamenya guhuza amashanyarazi binyuze mumashanyarazi.
5.2 Ingano n'uburemere
PackSMD ipakira: Nubwo ibice ari bito mubunini, ubunini bwabyo nuburemere biracyari bike kubera imiterere yububiko hamwe nibisabwa padi.
PackageOB paketi: Bitewe no gusiba pin yo hepfo hamwe na shell shell, pack ya COB igera kubintu byinshi bikabije, bigatuma pake iba nto kandi yoroshye.
5.3 Gushyushya imikorere
GapakiraSMD: Ahanini ikwirakwiza ubushyuhe binyuze muri padi na colloide, kandi ahantu ho gukwirakwiza ubushyuhe ni buke. Munsi yumucyo mwinshi hamwe nuburemere buremereye, ubushyuhe bushobora kuba bwibanze mukarere ka chip, bikagira ingaruka kubuzima no gutuza kwerekanwa.
PackageCOB pack: Chip irasudwa neza kuri PCB kandi ubushyuhe burashobora gukwirakwizwa mubuyobozi bwose bwa PCB. Igishushanyo gitezimbere cyane imikorere yubushyuhe bwo kwerekana no kugabanya igipimo cyo kunanirwa kubera ubushyuhe bwinshi.
5.4 Kuborohereza kubungabunga
GapakiraSMD: Kubera ko ibice byashizwe mu bwigenge kuri PCB, biroroshye cyane gusimbuza ikintu kimwe mugihe cyo kubungabunga. Ibi bifasha kugabanya amafaranga yo kubungabunga no kugabanya igihe cyo kubungabunga.
PackGapakira: Kubera ko chip na PCB byahujwe neza muri rusange, ntibishoboka gusenya cyangwa gusimbuza chip ukwayo. Iyo habaye amakosa, mubisanzwe birakenewe gusimbuza ikibaho cyose PCB cyangwa kuyisubiza muruganda kugirango isanwe, byongera ikiguzi nikibazo cyo gusana.
5.5
GapakiraSMD: Bitewe no gukura kwinshi nigiciro gito cy’umusaruro, ikoreshwa cyane ku isoko, cyane cyane mu mishinga itita ku biciro kandi isaba uburyo bworoshye bwo kuyitaho, nk'ibyapa byo hanze ndetse n'inkuta za televiziyo.
Gapakira COCOB: Bitewe nubushobozi buhanitse hamwe nuburinzi buhanitse, birakwiriye cyane cyane murwego rwohejuru rwimbere rwimbere rwimbere, kwerekana rusange, ibyumba byo kugenzura nibindi bice bifite ubuziranenge bwibisabwa hamwe nibidukikije bigoye. Kurugero, mubigo byategeka, sitidiyo, ibigo binini byohereza hamwe nibindi bidukikije aho abakozi bareba ecran igihe kirekire, tekinoroji yo gupakira COB irashobora gutanga uburambe bworoshye kandi bumwe.
Umwanzuro
Tekinoroji yo gupakira SMD hamwe na tekinoroji yo gupakira COB buriwese afite ibyiza byihariye hamwe nibisabwa mubijyanye na LED yerekana ecran. Abakoresha bagomba gupima no guhitamo ukurikije ibikenewe mugihe bahisemo.
Tekinoroji yo gupakira SMD hamwe na tekinoroji yo gupakira COB ifite ibyiza byayo. Tekinoroji yo gupakira ya SMD ikoreshwa cyane ku isoko kubera gukura kwinshi nigiciro gito cy’umusaruro, cyane cyane mu mishinga itita ku biciro kandi bisaba ko byoroha cyane. Ku rundi ruhande, tekinoroji yo gupakira COB, ifite ubushobozi bwo guhatanira gukomera mu nzu yo mu rwego rwo hejuru yerekana ibyerekanwe mu nzu, ibyerekanwa rusange, ibyumba byo kugenzura hamwe n’indi mirima hamwe n’ibipfunyika byegeranye, imikorere isumba iyindi, gukwirakwiza ubushyuhe n’uburyo bukomeye bwo kurinda.
