LED teeb pom kev siv thev naus laus zis tau txhim kho sai, muab kev lag luam thiab lub zog txuag hluav taws xob xaiv rau ntau yam kev siv. Chip Scale Package (CSP) thiab Surface Mount Device (SMD) yog ob txoj kev ntim LED nrov hauv kev siv niaj hnub no. Txawm hais tias muaj qee qhov txiaj ntsig thiab qhov tsis zoo ntawm lawv tus kheej, lawv tsis zoo ib yam hauv ntau txoj hauv kev. Qhov sib txawv ntawm SMD thiab CSP LED thev naus laus zis yuav raug suav nrog hauv kab lus no.
SMD LED: Nws yog dab tsi?
Nto Mount Ntaus Lub Teeb Emitting Diode yog hu ua SMD LED. Qhov tshwj xeeb ntawm LED pob no yog npaj rau kev siv nto mount. Lub rooj tsav xwm luam tawm (PCB) nrog lub me me LED nti nruab rau ntawm nws uas tau thaiv los ntawm kev puas tsuaj los ntawm cov yas los yog ceramic npog yog hu ua SMD LED. Lub pob cov neeg sib txuas ua rau nws tuaj yeem txuas thiab txuas ncaj qha rau PCB, uas ua kom yooj yim rau txoj kev teeb tsa.
Cov txiaj ntsig ntawm SMD LED
1. Muaj ntau qhov ntau thiab tsawg: SMD LED pob khoom muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov duab, uas ua rau nws yooj yim rau cov neeg tsim qauv xaiv cov pob zoo tagnrho rau lawv cov kev xav tau.
2. High brightness: SMD LED tej pob khoom yog zoo meej rau cov teeb pom kev zoo nyob rau hauv ntau yam kev siv vim hais tias lawv muaj peev xwm muab high brightness theem nrog tsawg zog noj.
3. Kev teeb tsa yooj yim: SMD LED pob khoom yooj yim rau nruab thiab tsis txhob hu rau cov cuab yeej tshwj xeeb lossis tshuab.
4. Lub neej ntev: SMD LED pob khoom tsis tas yuav hloov tau ntau xyoo vim lawv lub neej ntev.
Qhov tsis zoo ntawm SMD LED
1. Thaum tshav kub kub dissipation: Txhawm rau tiv thaiv cov nti LED los ntawm kev puas tsuaj, SMD LED pob yuav tsum muaj cov cua kub txaus thaum ua haujlwm.
2. thermal conductivity tsis zoo: SMD LED tej pob khoom yuav overheat vim hais tias lawv muaj ib tug tsis zoo thermal conductivity tshaj li cov pa pob khoom LED.
3. Txwv tsis pub muaj peev xwm: SMD LED pob yuav tsis tsim nyog rau kev siv hluav taws xob siab vim lawv lub peev xwm tsawg.
CSP LED: Nws yog dab tsi?
Chip Scale Pob Lub Teeb Emitting Diode yog hu ua CSP LED. Ib qho me me LED nti uas tso ncaj qha rau ntawm lub substrate yog suav nrog hauv cov pob LED no. Vim nws cov qib siab ci ntsa iab thiab qhov loj me me, CSP LED ntim yog ib qho kev siv thev naus laus zis tshiab uas tau dhau los ua neeg nyiam hauv kev lag luam.
Cov txiaj ntsig ntawm CSP LED
1. Compact me me: CSP LED pob khoom zoo meej rau cov xwm txheej uas qhov chaw txwv vim lawv me dua SMD LED pob.
2. High brightness: CSP LED tej pob khoom yog zoo meej rau cov teeb pom kev zoo nyob rau hauv ntau yam kev siv vim hais tias lawv muaj peev xwm muab high brightness theem nrog tsawg zog noj.
3. Txhim kho thermal kev ua tau zoo: CSP LED pob khoom ua tau zoo dua SMD LED pob khoom raws li kev ua haujlwm thermal raws li cov nti LED tau ncaj qha rau ntawm lub substrate.
4. Kev ntseeg siab: CSP LED pob khoom muaj lub neej ntev thiab muaj kev vam khom ntau dua li SMD LED pob khoom.
Qhov tsis zoo ntawm CSP LED
1. Txwv tsis pub muaj: Vim lawv lub hnub nyoog tsis ntev los no, CSP LED tej pob khoom yuav tsis muaj nyob rau hauv txhua qhov kev teeb tsa.
2. Cov nqi siab dua: CSP LED tej pob khoom yuav pheej yig dua rau qee daim ntawv thov vim lawv raug nqi ntau dua li cov pob SMD LED.
3. Kev sib dhos tshwj xeeb: Txhim kho CSP LED pob khoom yuav nyuaj dua li SMD LED pob khoom vim lawv xav tau kev sib dhos tshwj xeeb.
Hauv cov ntsiab lus:
Txhua yam ntawm LED thev naus laus zis-SMD thiab CSP-muaj cov txiaj ntsig thiab qhov tsis zoo. Lub pob LED zoo tagnrho rau koj daim ntawv thov yuav tso siab rau koj qhov kev xav tau tshwj xeeb thiab cov lus qhia tshwj xeeb. SMD LED pob khoom yog zoo meej rau sawb teeb pom kev zoo, backlighting, thiab signage, ntawm lwm yam kev siv. Lawv tsis xav tau cov cuab yeej tshwj xeeb lossis khoom siv, thiab lawv yooj yim rau nruab. Hloov pauv, CSP LED pob khoom zoo meej rau cov ntawv thov uas xav tau qib siab ci tab sis nrog thaj tsam tsawg. Lawv txhim khu kev qha heev thiab muaj kev ua haujlwm zoo thermal. Qhov sib txawv ntawm SMD thiab CSP LED thev naus laus zis tuaj yeem hloov pauv thaum cov thev naus laus zis tshiab tsoo lub khw txij li cov thev naus laus zis thev naus laus zis ib txwm hloov pauv. Nyob rau lub sijhawm no, paub txog yuav ua li cas ob lub thev naus laus zis sib txawv ntawm ib leeg tuaj yeem pab koj xaiv cov pob LED zoo tshaj plaws rau koj cov kev xav tau.
