Tig-Chip COB Display Manufacturing Process
Flip-Chip COB Display Manufacturing Process: Flip-Chip COB qhia siv COB flip-chip txheej txheem, uas txawv heev ntawm cov qauv SMD LED zaub ntau lawm txheej txheem. Cov txheej txheem tsim khoom tseem ceeb rau flip-chip COB cov lus qhia yog raws li hauv qab no:
* ** Chip Sorting:** LED chips raug soj ntsuam zoo thiab kev ua tau zoo.
Cov chips raug txheeb raws li qhov tsis xws li cov duab ci ntsa iab, wavelength, thiab voltage kom ntseeg tau tias lawv ua tau raws li cov qauv siv tom ntej.
* ** PCB Substrate Cleaning: ** PCB substrate yog huv si ua ntej encapsulation.
Plua plav, oxide txheej, thiab lwm yam impurities raug tshem tawm kom ntseeg tau tias muaj kev sib txuas zoo thiab hluav taws xob sib txuas.
* ** Daim Ntawv Thov Adhesive: ** Adhesive yog siv rau cov chaw tshwj xeeb ntawm PCB board kom ruaj ntseg LED chips.
Kev xaiv thiab daim ntawv thov ntawm cov nplaum yuav tsum muaj kev tswj xyuas kom ntseeg tau tias chip adhesion thiab du ua haujlwm ntawm cov txheej txheem tom ntej.
* **Chip Bonding:** Cov chips LED tau muab khi rau ntawm lub ntsej muag (flip-chip) rau cov nplaum-coated PCB substrate raws li tus qauv tau txiav txim siab thiab pixel suab.
Cov txheej txheem no yuav tsum tau muab tso rau qhov tseeb heev kom ntseeg tau tias pixel suab zoo ib yam thiab pom cov duab zoo. Soldering: Txuas cov nti cov electrodes rau cov ntaub so ntswg ntawm lub PCB substrate siv cov xov hlau kub los yog tooj liab.
Xyuas kom cov kis tau tus mob ntawm hluav taws xob teeb liab muab lub hauv paus rau kev ua hauj lwm ib txwm ntawm cov zaub.
Sealing: Npog lub teeb -emitting nti thiab soldered circuitry nrog ib txheej ntawm cov khoom siv polymer nyuaj.
Qhov no tiv thaiv cov nti, tiv thaiv kev cuam tshuam ib puag ncig ib puag ncig, txhim kho cov cua sov, thiab ua kom lub tiaj tiaj ntawm qhov screen.
Xws li cov txheej txheem kho cua sov kom ntseeg tau tias cov khoom siv saum npoo yog hardened tag.
Kev Ntsuas: Kev sim ua ntej yog ua tom qab kev sib khi tuag kom ntseeg tau tias cov nti ua haujlwm raug.
Kev ntsuas kev ua haujlwm ntxiv thiab optoelectronic kev ua tau zoo yog ua tom qab sib khi, suav nrog kev ua kom pom kev ci ntsa iab, xim sib xws, thiab kev kuaj pom pixel tuag.
Cov khoom tsis raug raug tshem tawm kom ntseeg tau tias qhov zoo ntawm cov khoom kawg.
Kho: Kho lossis hloov cov teeb meem uas pom thaum kuaj.
Xyuas kom cov khoom kawg ua tau raws li cov qauv.
Ntxuav thiab tshuaj xyuas: ntxuav cov khoom tiav thiab tshem tawm cov khoom txawv teb chaws ntau dhau.
Ua qhov kawg tshwm sim thiab kev tshuaj xyuas ua haujlwm kom ntseeg tau tias cov khoom ua tau raws li cov qauv kev xa khoom.
Warehousing: Cov khoom uas tau dhau tag nrho cov txheej txheem saum toj no thiab ua tau raws li cov qauv tsim nyog yog thaum kawg warehoused thiab npaj rau kev xa khoom.
Tag nrho cov txheej txheem tsim khoom ntawm flip-chip COB cov lus qhia yog qhov nyuaj thiab xav tau cov khoom siv zoo tshaj -. Kev tswj xyuas meej ntawm txhua theem yog qhov tseem ceeb rau kev tswj xyuas cov khoom zoo thiab ua tiav cov txiaj ntsig zoo thiab kev ua haujlwm ruaj khov ntawm flip-chip COB cov lus qhia.
