Dab tsi yog COB LED Zaub Qhov Tseeb?

Vim tias tib neeg nrhiav kev ua haujlwm siab ntawm ultra-siab txhais cov zaub, lub pixel suab ntawm LED cov lus yog tas li shrinking.

Raws li thawj tiam ntawm cov khoom siv thev naus laus zis, cov khoom siv SMD tsoos tau zoo heevtom qab ntau tshaj kaum xyoo ntawmkev loj hlob.

Yog li, txoj hauv kev twg thaum kawg yuav xav tau nyob rau hauv lub sijhawm ntawm micro coj zaub?

Nrog rau kev txhim kho ntawm LED zaub thev naus laus zis, txoj hauv kev xws li COB (uas luv luv rau Chip On Board) tawm los.

Tsis tas li ntawd, txoj kev ntim khoom sib txawv tuaj yeem ua ke nrog cov qauv chip sib txawv.

SMD, raws li lub npe hu ua nto mounted pab kiag li lawm, hais txog kev siv nto mount technology rau pob LED khoom.

Nws tuaj yeem thaiv lub khob khob, bracket, siv lead ua khoom, thiab lwm yam khoom siv rau hauv cov khoom sib txawv ntawm cov hlaws dai.

Thaum tsim cov khoom vaj huam sib luag nrog qhov sib txawv rau cov ntxaij vab tshaus LED, lub teeb hlaws yog welded rau lub rooj tsav xwm Circuit Court los ntawm kev kub ceev SMT tshuab nrog high-temperature reflow welding. 

Xav txog qhov teeb meem kev nyuaj thaum lub sij hawm encapsulation, manufacturers nyiam SMD los tsim qhov me me-spacing digital LED zaub screen.

SMD yog thawj thev naus laus zis rau micro LED cov ntxaij vab tshaus nrog pixel nrug tsawg dua 10 hli ntawm kev ua lag luam.

Ntawm qhov tod tes, COB, luv luv rau Chip On Board, yog lub tshuab ntim khoom tshiab uas encapsulates LED chips, tsis yog LED teeb, ncaj qha mus rau PCB.

Yog li ntawd, COB-LED yuav raug tso tawm los ntawm lub cev loj ntawm SMD rau kev daws teeb meem siab dua li P0.9375.

Digitalmicro coj cov ntxaij vab tshaus hauv P0.9375mm, P1.25mm, P1.5625mm thiab P1.875 muaj nrog COB.

Tsis tas li ntawd, nws yog qhov tsis lees paub tias COB muaj lub cev zoo dua.

Cov modules encapsulated nrog COB tsis tsuas yog sib dua li nrog SMD tab sis kuj muaj qhov pom loj dua.

Piv rau SMD, dab tsi COB coj zaub tuaj yeem nqa cov txiaj ntsig rau koj raws li hauv qab no:

1; Zoo heev tshav kub dissipation

Ib qho ntawm lub hom phiaj ntawm cov cuab yeej no yog los daws cov teeb meem ntawm cov cua sov dissipation ntawm SMD thiab DIP.

Cov qauv yooj yim muab nws qhov zoo dua li lwm ob hom hluav taws xob hluav taws xob.

2; Haum rau nqaim pixel suab LED Zaub

Raws li cov chips txuas ncaj qha rau PCB pawg thawj coj saib, qhov kev ncua deb ntawm txhua chav nyob yog nqaim kom txo cov pixel suab kom cov neeg siv khoom pom cov duab meej dua.

3; Simplify lub ntim

Raws li peb tau hais los saum no, cov qauv ntawm COB LED yog qhov yooj yim dua SMD thiab GOB, yog li cov txheej txheem ntim khoom kuj yooj yim, thiab.

4; Cov dej tsis muaj dej ntau dua

Nrog lub nti tshiab ntawm lub rooj tsavxwm ntawm cov nplaum nplaum, nws tuaj yeem tiv thaiv LED ntawm LED module los ntawm dej lossis av noo.

5; Zoo dua Anti-kev sib tsoo

Tshwj xeeb modular tsim nrog kev tiv thaiv kev sib tsoo gluing muaj peev xwm muaj kev ua haujlwm poob siab, muab kev tiv thaiv ultra-siab rau LEDs hauv ntau yam cuam tshuam.

6; Tshaj Dust-proof.

Nrog siab sealing kev ua tau zoo ntawm cov khoom tshiab, COB LED npo vaj huam sib luag los ntawm YONWAYTECH LED yog tag nrho cov plua plav tsis muaj qhov pom tseeb thiab muaj kev ua tau zoo ntawm kev pom zoo nrog siab refresh npaum li cas thiab xim uniformity.

Yog vim li cas rau qhov kev ntseeg siab yog tias COB thev naus laus zis tuaj yeem tshem tawm cov kev sib txuas tswj hauv tib lub teeb tsim cov txheej txheem.

Tsis tas li ntawd, nws tseem tshem tawm lub teeb hlaws hla cov txheej txheem reflow vuam, kom qhov kub thiab txias hauv cov txheej txheem ib txwm yuav tsis cuam tshuam rau LED nti thiab vuam kab.

Cov cua kub zoo heev thiab oxidation kuj tseem ua rau muaj kev ntseeg siab.

Dab tsi ntxiv, COB txais cov txheej txheem txheej txheem txheej txheem los tiv thaiv LED cov duab tsis ua haujlwm los ntawm dej, noo noo, UV, thiab lwm yam kev puas tsuaj.

Nws txhawb nqa txhua lub sijhawm huab cua thiab tseem tuaj yeem ua haujlwm hauv qhov kub thiab txias hauv -30 txog +80 degrees.

Cov txheej txheem tiv thaiv zoo tiv thaiv kev sib tsoo lossis khawb.

Lub mini LED zaub cov ntxaij vab tshaus tuaj yeem ntxuav nrog cov ntaub ntub dej yog tias muaj av.

Nrog rau cov ntaub ntawv saum toj no, koj tuaj yeem pom tias COB thev naus laus zis zoo dua rau SMD thev naus laus zis hauv LED zaub screen. 

Thiab yog tias koj tab tom nrhiavMicro LED zaub, koj tuaj yeem xa mus rau qee yam khoom ntawm YONWAYTECH LED DISPLAY.
