Waa maxay COB LED Display runtii?

 

Sababtoo ah raadinta bini'aadamka ee bandhiga qeexida aadka u sarreeya, booska pixel ee bandhigyada LED ayaa si joogto ah u sii yaraanaya.

Jiilkii ugu horreeyay ee tignoolajiyada bandhigga, bandhigga dhaqanka ee SMD wuxuu ahaa mid aad u bislaadayin ka badan toban sano ka dibhorumarin.

Marka, dariiqa farsamada ayaa ugu dambeyntii ku hamin doona xilliga bandhigga ledhka micro?

Iyada oo la horumarinayo tignoolajiyada bandhigga LED, dariiqyada farsamada sida COB(Taas oo gaaban Chip On Board) ayaa soo baxa.

Sidoo kale, dariiqyada baakadaha kala duwan ayaa la jaan qaadi kara qaabab kala duwan oo jajab ah.

Isbarbardhigga muraayadda smd iyo cob yonwaytech

 

SMD, oo loo yaqaan aaladaha dusha sare ku rakiban, waxaa loola jeedaa adeegsiga tignoolajiyada korka sare ee baakadaha LED.

Waxay koobin kartaa koob laambad, xajin, curiye crystal, iyo agabyo kale siyaalo kala duwan oo kuul laambad ah.

Marka la soo saarayo unugga bandhigga oo leh kala fogaansho kala duwan oo loogu talagalay muraayadaha muraayadaha yaryar ee LED, kuul nalka waxaa lagu dhejiyaa guddiga wareegga mashiinka SMT ee xawaaraha sare leh oo leh alxanka heerkulka sare. 

Iyadoo la tixgelinayo dhibaatada farsamada inta lagu jiro xiritaanka, wax-soo-saarayaashu waxay door bidaan SMD si ay u soo saaraan shaashadda LED-ga dhijitaalka ah ee yar-yar.

SMD waa tignoolajiyada aasaasiga ah ee muraayadaha muraayadaha LED-ka oo leh kala dheerayn pixel ka yar 10mm suuqa.

 

Tiknoolajiyada SMD COB

 

Dhanka kale, COB, oo loo soo gaabiyo Chip On Board, waa tikniyoolajiyad cusub oo baakad ah oo soo koobaysa chips-yada LED-ka, halkii ay ka ahaan lahaayeen nalalka LED-ka, si toos ah ugu gal PCB.

Sidaa darteed, COB-LED ayaa laga xorayn doonaa cabbirka jireed ee SMD ee xallinta sare sida P0.9375.

Digitalmuraayadaha muraayadaha LED-ka ee P0.9375mm, P1.25mm, P1.5625 mm iyo P1.875 ayaa la heli karaa COB.

Intaa waxaa dheer, lama dafiri karo in COB ay leedahay sifooyin jireed oo wanaagsan.

Qaybaha lagu duubay COB kaliya kama fududa kuwa SMD laakiin sidoo kale waxay leeyihiin aragti weyn.

Marka la barbar dhigo SMD, waxa COB-ka soo bandhigay wuxuu kuu keeni karaa faa'iidada sida hoos ku qoran:

 

1;Diidmada kulaylka aad u fiican

Mid ka mid ah ujeedooyinka farsamadan ayaa ah in wax laga qabto dhibaatada kulaylka ee SMD iyo DIP.

Qaab dhismeedka fudud wuxuu siinayaa faa'iidooyin ka badan labada nooc ee kale ee shucaaca kulaylka.

2;Ku habboon Muuqaalka LED-ka ee garoonka pixel dhuuban

Maaddaama ay chips-ku si toos ah ugu xidhan yihiin guddiga PCB-ga, masaafada u dhaxaysa unug kasta waa cidhiidhi si loo yareeyo garoonka pixel si macaamiisha loo siiyo sawirro cad.

3;Fududee baakooyinka

Sida aan kor ku soo sheegnay, qaab dhismeedka COB LED wuu ka fudud yahay SMD iyo GOB, markaa habka baakadku waa mid fudud, sidoo kale.

4;Heerka sare ee biyuhu

Iyada oo la adeegsanayo chip-ka cusub ee dusha sare ee moduleka dhejiska ah, waxay si fiican uga ilaalin kartaa LED-ka moduleka LED-ka biyaha ama qoyaanka.

5;Ka-hortagga isku dhaca ka fiican

Naqshadaynta qaab-dhismeedka gaarka ah ee leh isku-xidhka-ka-hortagga isku dhaca oo awood u leh inay yeeshaan shaqo caddayn shoog ah, oo bixisa ilaalin aadka u sarreeya ee LED-yada saamaynta kala duwan.

6;Ka gudba boodhka-ilaalinta.

Iyada oo waxqabadka shaabadeynta sare ee walxaha cusub, COB LED panel panel ka YONWAYTECH LED waa gebi ahaanba boodh-free oo leh caddayn aad u fiican waxayna bixisaa waxqabad muuqaal ah oo heer sare ah oo leh heerkul sare iyo midab isku mid ah.

 

P1.25 muuqaal wanaagsan oo toos ah

 

Sababta kalsoonida sare waa in tignoolajiyada COB ay baabi'in karto isku xirka xakamaynta ee habka wax soo saarka laambada keliya.

Intaa waxaa dheer, waxa ay sidoo kale ka saaraysaa kuul laambadda badan habka alxanka reflow, si heerkulka sare ee habka dhaqanka ma saamayn doono chip LED iyo line alxanka.

Kala-baxa kulaylka aadka u fiican iyo iska caabbinta oksaydhka ayaa sidoo kale gacan ka geysta kalsoonida sare.

Waxa intaa ka sii badan, COB waxay qabataa tignoolajiyada dahaarka heerka sare ah si ay uga hortagto fashilka soo bandhigida LED ee ay sababaan biyaha, qoyaanka, UV, iyo waxyeelada kale.

Waxay taageertaa hawlgalka hawada oo dhan waxayna wali ku shaqayn kartaa heerkul aad u daran -30 ilaa +80 digrii.

Habka ilaalinta dhamaystiran waxay ka hortagtaa isku dhaca ama xagashada.

Shaashado yar oo LED ah ayaa xitaa lagu nadiifin karaa maro qoyan haddii ay wasakhoobaan.

 

Macluumaadka kor ku xusan, waxaad ogaan kartaa in tignoolajiyada COB ay ka sarreyso tignoolajiyada SMD ee shaashadda shaashadda LED. 

Oo haddii aad raadinaysoBandhigyada Micro LED, waxaa laga yaabaa inaad tixraacdo qaar ka mid ah alaabada YONWAYTECH LED DISPLAY.
