Rau cov neeg xav nkag siab txog cov txheej txheem ntim khoom ntim LED, tsib kauj ruam hauv qab no yog cov ntaub ntawv tseem ceeb. Txhua kauj ruam muaj cov kev cai nruj heev rau kev huv huv ib puag ncig thiab cov khoom siv precision.
Kauj Ruam 1: Tuag Bonding
Qhov no yog qhov pib. Peb yuav tsum tau muab qhov chaw ntim cov chips LED ntom ntom rau ntawm wafer (tuag tsev cog khoom) kom yooj yim rau cov neeg hlau tuav. Tom ntej no los tuag bonding. Qhov no yog kauj ruam tseem ceeb tshaj plaws. Lub siab automated tuag bonder yuav tsum precisely tso cov chips rau ntawm substrate thiab ruaj ntseg lawv nrog nyiaj paste. Txawm tias qhov sib txawv ntawm ob peb micrometers los yog daim ntawv thov tsis sib xws ntawm cov nyiaj muab tshuaj txhuam tuaj yeem ua rau cov cua sov tsis zoo lossis tsis ruaj khov rau kev sib cuag hluav taws xob. Peb HengCai Electronics cov kab ntau lawm yog nruab nrog siab - qhov pom kev pom tseeb ntawm theem no kom ntseeg tau tias txhua lub nti yog qhov nruab nrab zoo kawg nkaus.
Kauj Ruam 2: Hlau Bonding - Tsim kev sib txuas hluav taws xob
Tom qab cov chips ruaj ntseg, lub zog yuav tsum tau muab. Qhov no yog qhov kev sib txuas ntawm cov xov hlau tuaj. Lub tshuab siv cov hlau zoo heev (feem ntau yog cov hlau kub, tsuas yog ib qho - feem kaum ntawm txoj kab uas hla ntawm tib neeg cov plaub hau) los txuas cov nti cov electrodes mus rau cov hlau lead ntawm lub mounting bracket. Qhov curvature ntawm cov hlau sib txuas, qhov nro, thiab cov duab ntawm cov pob solder tag nrho ua raws li cov qauv nruj. Cov kauj ruam no yog hu ua "lifeline" ntawm LED; Thaum tawg, LED yog kiag li siv tsis tau.
Kauj Ruam 3: Encapsulation Tom qab cov xov hlau txuas nrog, cov nti tseem raug. Hauv qhov no, yuav tsum tau encapsulation. Rau cov LEDs dawb, peb yuav tsum tau muab cov phosphor sib xyaw ua ke hauv cov nplaum. Qhov no yog ib qho kev kos duab zoo nkauj, thiab ib qho tseem ceeb zais cia ntawm txhua qhov chaw ntim khoom. Txawm tias me ntsis mismatch yuav ua rau ib tug bluish los yog yellowish tint rau lub teeb. Cov nplaum nplaum npaj tau muab tso rau hauv lub khob bracket, npog cov nti thiab cov xov hlau kub, thiab tom qab ntawd muab tso rau hauv qhov cub kom siab -kub curing. Cov txheej txheem no tiv thaiv cov qauv sab hauv thiab ua tiav lub teeb xim hloov dua siab tshiab.
Kauj Ruam 4: Lead Cutting thiab Sorting Tom qab kho, cov LEDs tseem txuas nrog rau tag nrho cov bracket. Peb yuav tsum siv lub tshuab txiav cov hlau lead los txiav lawv rau hauv ib tus neeg LEDs. Tom qab ntawd lawv nkag mus rau theem sorting. Tsis yog txhua txhua LED nti tsim tau zoo ib yam. Lub tshuab sorting categorizes cov chips rau hauv qib sib txawv (hauv cheeb tsam) raws li qhov tsis xws li qhov ci, qhov hluav taws xob, thiab xim (wavelength).
Voltage Consistency
Xim Temperature Consistency (SDCM)
Kev ci ntsa iab ua kom ntseeg tau tias txhua pob ntawm cov chips cov neeg siv khoom tau txais cov teeb pom kev zoo ib yam thaum npaj rau ntawm phab ntsa.
Kauj Ruam 5: Ntim thiab Kev Ntsuas Cov kauj ruam kawg yog daim kab xev ntim thiab kev sim zaum kawg. Peb muab cov dej noo- pov thawj ntim rau cov khoom tiav thiab ua cov kev ntsuam xyuas kev laus. Yog tias koj xav paub ntau ntxiv txog yuav ua li cas peb ua kom zoo ntawm txhua qhov LED nti tawm hauv lub Hoobkas, thov mus saib peb lub vev xaib https://www.h-cled.com/ kom paub meej txog kev ua qauv qhia ntawm peb cov khoom siv kuaj. Peb yuav tsum xyuas kom meej tias peb cov khoom txuas ntxiv ua haujlwm ruaj khov txawm tias nyob hauv qhov chaw huab cua.
