SMD Vs. COB LED zaub ntim tshuab

1. Taw qhia rau SMD Lub Tshuab Ntim Tshuab

1.1 Kev txhais thiab tom qab ntawm SMD

SMD Kev Siv Tshuab Ntim yog ib daim ntawv ntawm cov hluav taws xob hauv hluav taws xob. SMD, uas sawv rau cov khoom siv hluav taws xob nto, yog cov tshuab hluav taws xob ua lag luam rau kev tsim khoom lag luam Circuitated lossis lwm yam hluav taws xob ua ncaj qha rau saum npoo ntawm PCB (luam tawm cov boardcuit Court board).

1.2 cov yam ntxwv tseem ceeb

Qhov loj me:SMD ntim khoom yog cov kev sib xyaw ua ke, ua rau muaj kev sib koom ua ke siab, uas muaj txiaj ntsig zoo rau kev tsim cov miniaturized thiab qaim hluav taws xob khoom.

Lub teeb hnyav:SMD Cheebtsam tsis tas ua cov hmoov txhuas, ua cov qauv txheej txheem tag nrho thiab haum rau cov ntawv thov uas yuav tsum tau txiav tawm.

Cov yam ntxwv zoo heev:Cov ris tsho luv luv thiab kev sib txuas hauv SMD Cheebtsam yuav pab txo qhov tsis pom kev thiab kev tawm tsam, txhim kho kev ua haujlwm siab.

Haum rau kev ua lag luam:SMD Cheebtsam yog haum rau automated tso machine, nce ntau lawm kev ua haujlwm thiab zoo ruaj khov.

Zoo thermal Performance:SMD Cheebtsam muaj kev sib cuag ncaj qha nrog PCB saum npoo, uas pab AIDS hauv tshav kub dissipation thiab txhim kho cov cua sov.

Yooj yim kho thiab tswj:Cov txheej txheem saum npoo av ntawm SMD Cheebtsam ua rau nws kho tau yooj yim dua thiab hloov cov khoom siv.

Hom Ntim Hom:SMD ntim suav nrog ntau hom xws li sawm, qfn, BGA, thiab LGA, txhua tus nrog cov txiaj ntsig tshwj xeeb thiab muaj cov xwm txheej muaj feem xyuam.

Kev txhim kho thev naus laus zis:Txij li nws cov lus qhia, smd ntim technology tau dhau los ua ib qho ntawm cov tshuab ntim hluav taws xob hauv cov tshuab hluav taws xob kev lag luam. Nrog thev naus laus zis thiab kev xav ua lag luam, SMD Technology txuas ntxiv kom tau raws li qhov kev xav tau ntawm kev kawm tau zoo dua, thiab cov nqi qis dua.

2. Kev tsom xam ntawm COB ntim tshuab ntim tshuab

2.1 Kev Txhais Lus thiab Tom Qab COB

COB Ntim thev naus laus zis, uas sawv rau nti ntawm Board, yog cov txheej txheem ntim ntim uas muaj cov chips ncaj qha rau ntawm PCB (luam tawm Circuit Court Board). Cov thev naus laus zis no feem ntau siv los tshaj tawm coj cov teeb meem tsis txaus ntseeg thiab ua tiav kev sib koom ua ke nruj ntawm nti thiab cov Circuit Court Board.

2.2 Txheej txheej

COB ntim suav nrog txuas cov nqaij liab qab rau kev sib txuas lus lossis cov nplaum tsis ua haujlwm los ntawm kev sib txuas hlau los tsim cov khoom siv hluav taws xob. Thaum ntim khoom, yog tias cov kua liab liab tau nthuav tawm rau huab cua, nws tuaj yeem ua paug lossis puas. Yog li ntawd, cov nplaum nplaum feem ntau siv los encapsulate lub nti thiab sib txuas xov hlau, ua "encapsulation" mos. "

2.3 Txuj Ci

Compact ntim: los ntawm kev sib xyaw ntim nrog cov PCB, qhov loj me nce, cov qauv siv hluav taws xob ua kom zoo, thiab cov txheej txheem ruaj khov txhim kho.

Cov Ruaj Ntseg Zoo: Cov cim ncaj qha rau lub PCB ua rau muaj kev sib tw zoo thiab poob siab nyob hauv ib puag ncig hnyav thiab av noo, uas muaj kev ncua cov khoom siv nyiaj txiag.

Zoo heev Thermal conductivity: Siv thermal conductive adhesives ntawm lub nti thiab pcb zoo txhim kho cua sov, txo thermal cuam tshuam rau ntawm lub nti thiab txhim kho chip lifespan.

Tsawg tus nqi tsim khoom: Tsis tas yuav ua, nws tshem tawm qee cov txheej txheem nyuaj uas muaj cov nqi txuas ntxiv thiab ua tus nqi tsim khoom lag luam. Ib qho ntxiv, nws tso cai rau kev siv tshuab, txo qis cov nqi zog thiab txhim kho kev tsim khoom.

2.4 ceev faj

Nyuaj nyuaj rau kev kho: Ua rau soldering rau tus PCB ua rau tus kheej tshem tawm lossis hloov tsis yooj yim, feem ntau yuav tsum tau hloov ntawm tus PCB, nce thiab kho teeb meem.

Kev ntseeg teeb meem: Chips kos rau hauv cov nplaum muaj peev xwm ua tau zoo thaum lub sijhawm tshem tawm, muaj peev xwm ua rau lub ncoo puas thiab cuam tshuam rau ntau lawm.

Cov txheej txheem ntim cov khoom lag luam siab: Cov txheej txheem ntim khoom siv ntim plua plav kom tau muaj ib qho chaw tsis muaj hmoov av, ib puag ncig zoo li qub; Txwv tsis pub, qhov tsis ua tiav tus nqi nce.

3. Piv ntawm SMD thiab COB

Yog li, dab tsi yog qhov sib txawv ntawm ob qhov thev naus laus zis?

3.1 sib piv ntawm kev pom kev

Cob qhia, nrog lawv cov yam ntxwv teeb hluav taws xob, muab cov neeg saib nrog cov kev pom zoo thiab ntau qhov kev pom zoo. Piv rau lub ntsiab lus teeb ci

3.2 Kev sib piv ntawm kev ruaj khov thiab kev saib xyuas

Thaum smd cov lus qhia tau yooj yim kho rau ntawm qhov chaw, lawv muaj kev tiv thaiv tag nrho txhua qhov kev tiv thaiv ntau yam. Nyob rau hauv kev sib piv, hais txog lawv tag nrho ntim tsim qauv, muaj ntau cov qib siab tiv thaiv, nrog kev ua kom zoo dua qub thiab plua plav. Txawm li cas los xij, nws yuav tsum raug sau tseg tias Cob cov lus qhia feem ntau yuav tsum tau xa rov qab mus rau lub Hoobkas rau kev ua haujlwm thaum tsis ua tiav.

3.3 Kev Siv Hluav Taws Xob thiab Kev Siv Hluav Taws Xob

Nrog ib tug txheej txheem flipstructed, COB muaj cov peev txheej ntau dua rau kev siv zog qis rau tib lub ci ci, txuag cov neeg siv hluav taws xob.

3.4 tus nqi thiab kev loj hlob

SMD lub tshuab siv tshuab tau siv dav yog siv ntau dua vim nws cov nqi loj hlob zoo thiab tsis muaj nqi ntau lawm. Txawm hais tias COB thev naus laus zis muaj cov nqi qis dua, nws cov txheej txheem sib xyaw ua ke thiab cov txiaj ntsig qis tus nqi tam sim no ua rau cov nqi siab dua tiag tiag. Txawm li cas los xij, raws li thev naus laus zis thiab ntau lawm muaj peev xwm nthuav tawm, tus nqi ntawm COB yuav tsum tau txo qis dua.

4. Yav Tom Ntej Kev Loj Hlob

Rtled yog ib tug tho kev hauv COB LED zaub thev naus laus zis. Peb liCOB LED qhiayog siv dav hauvTxhua Yam Ntawm Kev Lag Luam LED QhiaVim lawv cov nyhuv zoo heev thiab ua tau zoo. RTLL tau cog lus los muab cov kev daws teeb meem zoo, ib-nres cov kev daws teeb meem kom tau raws li peb cov neeg siv khoom siv rau cov lus qhia siab thiab kev tiv thaiv kev txuag hluav taws xob thiab kev txuag hluav taws xob. Peb txuas ntxiv ua kom zoo rau peb cov khoom siv thev naus laus zis los coj peb cov neeg siv khoom sib tw ntau dua los ntawm kev txhim kho cov nqi teeb pom kev zoo thiab txo cov nqi tsim khoom.
