SMD vs COB LED Zaub Ntim Tshuab

1. Taw qhia rau SMD Ntim Tshuab

1.1 Kev txhais thiab keeb kwm ntawm SMD

SMD ntim tshuab yog ib hom kev ntim khoom siv hluav taws xob. SMD, uas sawv cev rau Surface Mounted Device, yog ib qho cuab yeej siv dav hauv kev lag luam hluav taws xob tsim khoom rau ntim cov khoom siv hluav taws xob los yog lwm yam khoom siv hluav taws xob kom ncaj qha rau ntawm qhov chaw ntawm PCB (Printed Circuit Board).

1.2 Lub ntsiab nta

Qhov Loj:SMD ntim cov khoom yog compact, ua kom muaj kev sib koom ua ke siab, uas yog qhov zoo rau kev tsim cov khoom siv hluav taws xob me me thiab lub teeb yuag.

Lub teeb nyhav:SMD Cheebtsam tsis xav tau kev coj ua, ua rau tag nrho cov qauv hnav thiab haum rau cov ntawv thov uas yuav tsum tau txo qhov hnyav.

Cov yam ntxwv zoo heev High-Frequency:Cov coj luv luv thiab kev sib txuas hauv SMD Cheebtsam pab txo qis inductance thiab tsis kam, txhim kho kev ua haujlwm siab.

Haum rau Automated Production:SMD Cheebtsam yog tsim rau automated qhov chaw tshuab, ua kom ntau lawm efficiency thiab zoo stability.

Kev ua haujlwm zoo thermal:SMD Cheebtsam yog nyob rau hauv kev sib cuag ncaj qha nrog PCB nto, uas pab nyob rau hauv tshav kub dissipation thiab txhim kho thermal kev ua tau zoo.

Ib qho yooj yim kho thiab tu:Txoj kev nto-mount ntawm SMD cov khoom ua kom yooj yim kho thiab hloov cov khoom.

Ntim Hom:SMD ntim suav nrog ntau hom xws li SOIC, QFN, BGA, thiab LGA, txhua qhov tshwj xeeb muaj txiaj ntsig thiab siv tau.

Kev tsim kho technology:Txij li thaum nws cov kev taw qhia, SMD ntim tshuab tau dhau los ua ib qho ntawm cov khoom siv ntim khoom loj hauv kev tsim khoom siv hluav taws xob. Nrog rau kev txhim kho thev naus laus zis thiab kev lag luam xav tau, SMD thev naus laus zis txuas ntxiv hloov kho kom tau raws li qhov xav tau ntawm kev ua tau zoo dua, qhov me me, thiab cov nqi qis dua.

2. Kev soj ntsuam ntawm COB Ntim Tshuab

2.1 Kev txhais thiab keeb kwm ntawm COB

COB ntim tshuab, uas sawv cev rau Chip on Board, yog cov txheej txheem ntim khoom uas cov chips tau ncaj qha rau ntawm PCB (Printed Circuit Board). Cov thev naus laus zis no feem ntau yog siv los daws teeb meem LED kub dissipation thiab ua tiav kev sib koom ua ke ntawm cov nti thiab lub rooj tsav xwm Circuit Court.

2.2 Technical Principple

Kev ntim khoom COB suav nrog txuas cov chips liab qab rau qhov sib txuas sib txuas siv cov khoom siv hluav taws xob lossis cov nplaum tsis muaj hluav taws xob, ua raws li kev sib txuas ntawm cov xov hlau los tsim kev sib txuas hluav taws xob. Thaum lub sij hawm ntim, yog tias cov nti liab qab raug rau huab cua, nws tuaj yeem kis tau los yog puas. Yog li ntawd, cov nplaum feem ntau yog siv los encapsulate cov nti thiab cov xov hlau sib txuas, ua rau "mos encapsulation."

2.3 Technical nta

Compact Packaging: Los ntawm kev sib xyaw ntim nrog PCB, nti loj tuaj yeem txo qis, qib kev sib xyaw ua ke tau nce, kev tsim hluav taws xob tau zoo dua qub, qhov nyuaj hauv Circuit Court txo qis, thiab kev ruaj ntseg zoo dua.

Kev ruaj ntseg zoo: Kev sib txuas ncaj nraim ntawm PCB ua rau muaj kev co zoo thiab kev poob siab, tswj kev ruaj ntseg hauv qhov chaw hnyav xws li kub thiab av noo, yog li txuas ntxiv cov khoom lag luam.

Cov Khoom Siv Hluav Taws Xob Zoo Tshaj Plaws: Siv cov thermal conductive nplaum nruab nrab ntawm cov nti thiab PCB zoo txhim kho cov cua sov dissipation, txo cov thermal cuam tshuam ntawm nti thiab txhim kho nti lifespan.

Tus nqi tsim khoom qis: Tsis tas yuav tsum muaj kev coj ua, nws tshem tawm qee cov txheej txheem nyuaj uas cuam tshuam nrog cov khoom sib txuas thiab cov coj, txo cov nqi tsim khoom. Tsis tas li ntawd, nws tso cai rau automated ntau lawm, txo cov nqi zog thiab txhim kho kev tsim khoom.

2.4 Kev ceev faj

Kho nyuaj: Kev sib txuas ncaj qha ntawm cov nti rau PCB ua rau ib tus neeg nti tshem tawm lossis hloov tsis tau, feem ntau yuav tsum tau hloov tag nrho PCB, nce nqi thiab kho nyuaj.

Cov teeb meem kev ntseeg tau: Cov chips embedded rau hauv cov nplaum tuaj yeem raug puas tsuaj thaum lub sij hawm tshem tawm cov txheej txheem, uas yuav ua rau lub ncoo puas thiab cuam tshuam rau kev tsim khoom.

Kev xav tau ib puag ncig siab: COB ntim txheej txheem xav tau ib puag ncig tsis muaj plua plav, zoo li qub; txwv tsis pub, qhov tsis ua hauj lwm nce.

3. Kev sib piv ntawm SMD thiab COB

Yog li, dab tsi yog qhov txawv ntawm ob lub thev naus laus zis no?

3.1 Sib piv ntawm Kev Pom Kev Pom Kev

COB cov lus qhia, nrog rau lawv cov yam ntxwv ntawm lub teeb pom kev zoo, muab cov neeg saib nrog cov kev paub pom zoo dua thiab ntau dua. Piv nrog rau qhov chaw teeb pom kev zoo ntawm SMD, COB muaj cov xim zoo nkauj dua thiab kev nthuav dav zoo dua, ua rau nws tsim nyog rau lub sijhawm ntev, saib ze.

3.2 Kev sib piv ntawm kev ruaj ntseg thiab kev ruaj ntseg

Thaum SMD cov lus pom tau yooj yim kho ntawm qhov chaw, lawv muaj kev tiv thaiv tsis muaj zog thiab muaj kev cuam tshuam ntau rau ib puag ncig. Hauv qhov sib piv, COB cov lus qhia, vim lawv cov qauv ntim tag nrho, muaj kev tiv thaiv ntau dua, nrog kev ua haujlwm zoo dua dej thiab plua plav. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias COB cov lus qhia feem ntau yuav tsum tau xa rov qab mus rau lub Hoobkas rau kev kho thaum tsis ua haujlwm.

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

Nrog rau cov txheej txheem flip-chip uas tsis muaj kev cuam tshuam, COB muaj lub teeb pom kev zoo dua, ua rau qis zog siv rau tib lub teeb ci, txuag cov neeg siv ntawm cov nqi hluav taws xob.

3.4 Tus Nqi thiab Kev Txhim Kho

SMD ntim tshuab tau dav siv vim nws qhov kev loj hlob thiab cov nqi qis. Txawm hais tias COB theoretical theoretically muaj cov nqi qis, nws cov txheej txheem tsim khoom thiab cov nqi qis qis tam sim no ua rau cov nqi qis dua. Txawm li cas los xij, raws li kev siv thev naus laus zis thiab kev tsim muaj peev xwm nthuav dav, tus nqi ntawm COB xav tias yuav txo qis ntxiv.
