Tso lus

Nrog txoj kev loj hlob sai ntawm kev lag luam kev lag luam hauv xyoo tas los no, LED cov ntxaij vab tshaus, uas yog ib feem tseem ceeb ntawm nws, tau dhau los ua kev tsim kho tshiab nrog txhua hnub dhau mus. Ntawm ntau cov thev naus laus zis, SMD (Surface Mount Device) ntim tshuab thiab COB (Chip on Board) ntim tshuab yog qhov tshwj xeeb qhov muag. Niaj hnub no, peb yuav txheeb xyuas qhov sib txawv ntawm ob lub thev naus laus zis no hauv txoj kev nkag siab yooj yim thiab coj koj los ua kom txaus siab rau lawv qhov ntxim nyiam.

Ua ntej, cia peb pib nrog cov txheej txheem. SMD ntim tshuab yog ib hom kev ntim khoom siv hluav taws xob. SMD, lub npe tag nrho uas yog Surface Mounted Device, txhais tau tias nto mount ntaus ntawv. Nws yog ib qho cuab yeej siv dav hauv kev lag luam hluav taws xob tsim khoom rau kev ntim cov khoom siv hluav taws xob sib txuas lossis lwm yam khoom siv hluav taws xob kom lawv tuaj yeem ncaj qha rau ntawm qhov chaw ntawm PCB (luam tawm Circuit Board).

COB ntim tshuab, lub npe puv Chip on Board, yog lub tshuab ntim khoom uas ncaj qha solders lub nti ntawm PCB (Printed Circuit Board). Cov thev naus laus zis no feem ntau yog siv los daws qhov teeb meem kub ntxhov ntawm LEDs thiab ua tiav kev sib koom ua ke ntawm cov chips thiab circuit boards.

Chip on Board Mainly used to solve LED heat dissipation problems1

Lub hauv paus ntsiab lus tseem ceeb: COB ntim yog ua raws li cov nti liab qab mus rau qhov sib txuas sib txuas nrog cov kua nplaum lossis cov kua nplaum, thiab tom qab ntawd ua cov hlua khi kom ua tiav nws cov hluav taws xob sib txuas. Thaum lub sij hawm ntim cov txheej txheem, yog tias cov nti liab qab raug ncaj qha rau saum huab cua, nws raug cuam tshuam rau kev sib kis lossis tib neeg kev puas tsuaj, yog li cov nti thiab cov xov hlau txuas feem ntau yog ntim nrog cov kua nplaum los ua qhov hu ua "soft encapsulation".

Cov yam ntxwv nta: Kev ntim khoom ntim: Txij li lub pob thiab PCB sib xyaw ua ke, cov nti loj tuaj yeem txo qis, kev sib koom ua ke tuaj yeem txhim kho, thiab kev tsim hluav taws xob tuaj yeem ua kom zoo dua qub, qhov kev sib tw hauv Circuit Court tuaj yeem txo qis, thiab kev ruaj ntseg system tuaj yeem ua tau. txhim kho.

COB packaging is to adhere the bare chip to the interconnect substrate with conductive or non-conductive glue and then perform wire bonding to achieve its electrical connection1

Kev ruaj ntseg zoo: Cov nti yog ncaj qha soldered ntawm PCB, yog li nws muaj kev co zoo thiab kev cuam tshuam, thiab tuaj yeem nyob ruaj khov hauv qhov chaw hnyav xws li kub thiab av noo, txuas lub neej ntawm cov khoom.

Zoo thermal conductivity: Siv thermal conductive kua nplaum ntawm cov nti thiab PCB tuaj yeem txhim kho cov cua sov kom zoo, txo qhov cuam tshuam ntawm tshav kub ntawm nti, thiab ua rau lub neej nti.

Tus nqi tsim khoom qis: Tsis tas yuav tsum muaj pins, uas tshem tawm qee cov txheej txheem nyuaj ntawm cov khoom sib txuas thiab cov pins hauv cov txheej txheem tsim khoom thiab txo cov nqi npaj. Nyob rau tib lub sijhawm, nws tuaj yeem paub txog kev tsim khoom, txo cov nqi zog, thiab txhim kho kev tsim khoom.

Good stability good thermal conductivity low manufacturing cost1

Lus Cim: Kev tu ncua tsis yooj yim: Txij li cov nti thiab PCB tau ncaj qha welded, nws tsis tuaj yeem disassemble lossis hloov cov nti sib cais. Feem ntau, tag nrho PCB yuav tsum tau hloov, uas ua rau kom tus nqi thiab qhov nyuaj ntawm kev saib xyuas.

Kev ntseeg siab tsis zoo: Lub nti yog embedded nyob rau hauv cov nplaum, thiab cov txheej txheem dissolution yog ib qho yooj yim rau kev puas tsuaj rau lub micro-disassembly thav duab, uas yuav ua rau lub ncoo ploj lawm thiab cuam tshuam rau cov kev xav ntau lawm.

Cov kev cai ib puag ncig siab thaum lub sij hawm tsim khoom: COB ntim tsis pub plua plav, hluav taws xob zoo li qub thiab lwm yam kev ua qias tuaj hauv qhov chaw ua haujlwm, txwv tsis pub nws yog ib qho yooj yim kom nce tus nqi tsis ua haujlwm.

Difficult maintenance reliability difficulties high environmental requirements during production1

Feem ntau, COB ntim tshuab yog tus nqi-zoo thiab zoo heev technology nrog dav daim ntawv thov muaj peev xwm nyob rau hauv lub teb ntawm ntse electronics. Nrog rau kev txhim kho ntxiv ntawm kev siv thev naus laus zis thiab kev nthuav dav ntawm daim ntawv thov scenarios, COB ntim tshuab yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb.

COB packaging technology is a cost-effective and excellent technology with wide application potential in the field of smart electronics1

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

Kev pom kev pom: COB zaub, nrog rau nws cov yam ntxwv ntawm lub teeb pom kev zoo, coj qhov muag pom kev zoo dua thiab zoo ib yam rau cov neeg tuaj saib. Piv nrog rau SMD lub teeb pom kev zoo, COB muaj cov xim ci dua, kev nthuav dav zoo dua, thiab yog qhov tsim nyog rau kev saib mus ntev.

Kev ruaj ntseg thiab kev ruaj ntseg: Txawm hais tias SMD cov ntxaij vab tshaus tau yooj yim kho ntawm qhov chaw, lawv cov kev tiv thaiv tag nrho tsis muaj zog thiab lawv yooj yim cuam tshuam los ntawm ib puag ncig sab nraud. COB cov ntxaij vab tshaus, ntawm qhov tod tes, muaj kev tiv thaiv qib siab dua vim lawv cov qauv ntim tag nrho, thiab zoo dua ntawm kev tiv thaiv dej thiab plua plav. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias thaum muaj kev txhaum tshwm sim, COB cov ntxaij vab tshaus feem ntau yuav tsum tau xa rov qab mus rau lub Hoobkas kho.

Kev siv hluav taws xob thiab kev siv hluav taws xob: Txij li COB siv cov txheej txheem flip-chip tsis muaj kev cuam tshuam, nws lub teeb pom kev zoo dua thiab kev siv hluav taws xob qis dua ntawm tib lub teeb ci, txuag cov neeg siv hluav taws xob siv hluav taws xob.

Tus nqi thiab kev loj hlob: SMD ntim tshuab yog dav siv nyob rau hauv kev ua lag luam vim nws loj hlob thiab tsis tshua muaj nqi. Txawm hais tias COB tshuab yog theoretically pheej yig dua, nws cov nqi tiag tiag kuj tseem siab vim nws cov txheej txheem ntau lawm thiab tsis tshua muaj txiaj ntsig. Txawm li cas los xij, nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev nthuav dav ntawm cov peev txheej ntau lawm, tus nqi ntawm COB xav tias yuav raug txo ntxiv.

What is the difference between COB and SMD technology

Niaj hnub no, nyob rau hauv kev lag luam zaub lag luam, COB thiab SMD ntim technologies muaj lawv tus kheej zoo. Nrog rau qhov kev thov loj hlob rau cov lus qhia siab, Micro LED cov khoom lag luam nrog cov pixel ceev dua tau maj mam nyiam los ntawm kev ua lag luam. COB thev naus laus zis, nrog nws cov yam ntxwv ntim khoom sib xyaw ua ke, tau dhau los ua ib qho ntawm cov thev naus laus zis tseem ceeb kom ua tiav siab pixel ceev ntawm Micro LED. Nyob rau tib lub sijhawm, raws li cov ntsiab lus ntawm cov ntxaij vab tshaus LED txuas ntxiv zuj zus, tus nqi kom zoo dua ntawm COB thev naus laus zis tau dhau los ua qhov tseem ceeb.

Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm thev naus laus zis thiab kev ua lag luam tsis tu ncua, COB thiab SMD ntim thev naus laus zis yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev lag luam khoom lag luam. Peb muaj laj thawj ntseeg tias nyob rau yav tom ntej, ob lub thev naus laus zis no yuav sib koom ua ke txhawb kev lag luam kev lag luam kom txhim kho cov ntsiab lus siab dua, ntse dua thiab ntau tus phooj ywg ib puag ncig. Cia peb tos thiab pom, thiab ua tim khawv lub sijhawm zoo siab ua ke!
