Kev ua ntawm SMD LED
Daim ntawv thov kev ceeb toom no piav qhia qhov tseem ceeb ntawm cov yam tseem ceeb thiab muaj feem cuam tshuam txog kev ua haujlwm ntawm SMD LEDs.
A. Taw qhia
Feem ntau, LEDs tsis txawv ntawm kev ua los ntawm lwm cov khoom siv hluav taws xob SMD. Txawm li cas los xij, vim tias lawv cov khoom siv kho qhov muag tshwj xeeb cov khoom ntim khoom tuaj yeem ua rau muaj kev nkag siab ntau dua, thiab yog li cov LEDs tuaj yeem ua rau nrawm nrawm lossis tej zaum yuav ua tsis tiav nrog rau lawv cov khoom siv hluav taws xob kho qhov muag yog tias lawv tsis ua haujlwm raug lossis ua ke. Nrog kev txhim kho me me thiab kev xav tshiab pob, kev xav tau rau kev ua LED tau dhau los ua qhov xav tau ntau dua, piv txwv li ntawm kev sib dhos thiab txheej txheem txheej txheem. Nrog lub zog loj me me tshiab LEDs nws yog piv txwv qhov tseem ceeb uas cov txheej txheem soldering tau tsim thiab yoog raws li qhov tsis xws luag (voids) hauv cov khoom sib txuas tau raug txo kom tsawg. Tsawg tus naj npawb ntawm cov voids, tshwj xeeb tshaj yog ntawm cov thermalpad ntawm LED, zoo dua cov thermal txuas rau PCB thiab yog li qis thermal load. Qhov no ua rau cuam tshuam rau kev ua haujlwm thiab lub neej ntawm LED.Qhov peev xwm ntawm kev cuam tshuam yog ntau yam hauv cov xwm txheej no thiab feem ntau tsis tau txiav txim siab los ntawm ib qib nkaus xwb. Yam tseem ceeb xws li kev ua tiav cov khoom, cov khoom siv thiab cov khoom sib xyaw ntawm cov laug, tsim cov kab laug sab laug, rov ua dua cov kab hlau rhuav lossis txheej txheem txheej txheem cuam tshuam nrog thiab ua rau cov txiaj ntsig zoo dua.
Kev ua haujlwm zoo ntawm SMD LEDs los ntawm OSRAM Opto Semiconductorsis tau hais tseg hauv qab no. Cov yam tseem ceeb thiab yam tseem ceeb ntawm kev cuam tshuam hauv cov txheej txheem kev tsim khoom tau piav qhia.
B. SMD LEDs
SMD (Surface mounted device) LEDs feem ntau txhais tau tias yog cov khoom siv nrog cov pob khoom uas tuaj yeem muab ncaj qha mus rau saum npoo ntawm cov ntawv luam tawm Circuit boardvia cov khoom muaj peev xwm sib cuag. Cov yas yas sib xyaw ua ke, ceramic lossis epoxysubstrates tau siv rau pob, nrum nrog epoxy lossis silicone. Raws li pob hom thiab kev hloov pauv, kev sib cuag ntawm cov khoom siv LED ib txwm muaj feem ntau tsim ua Gull-Wing lossis J-Leads. Nrog hom tshiab ntawm pob ntawv, tshwj xeeb tshaj yog rau ntim ntau dua ntom ntom ntom ntom, cov pob qij txha txuas tau yog cov hlau me-txheej txuas rau sab nraub qaum ntawm pob (hauv qab tsuas yog txiav? (BoT)). Daim duab 1 qhia txog kev xaiv los ntawm SMD LED cov ntaub ntawv ntawm OSRAM Opto Semiconductors.
Raws li nrog txhua yam khoom lag luam los ntawm OSRAM Opto Semiconductors, tseem nws SMD LEDs ua kom tiav cov txheej txheem RoHS tam sim no (European Union& Tuam Tshoj), thiab yog li ntawd tsis muaj cov hlau lead lossis lwm yam tshuaj muaj kev phom sij.
Vim lawv qhov ntev geometric, pib nrog qhov loj me ntawm kwv yees li. 1 hli txog 10 hli, SMD LEDs yog cov khoom me me thiab tau ntim rau hauv cov yas yas vim lawv feem ntau xav tau ntau dua. Cov kab xev nrog qhov ntev ntawm 8 hli mus rau 24 hli tau muab tso rau ntawm ib txoj hlua, qhov uas cov ntawv loj thiab qhov ntau ntawm cov yob yog nyob ntawm daim ntawv ntawm LED. Qhov ntev ntawm daim kab xev -LED tshwj xeeb los ntawm OSRAM Opto Semiconductors tau ua raws IEC 60286-3, EIA 481-C thiab tuaj yeem pom ntawm lub vev xaib hauv Cov Khoom Catalogsection, hauv tshooj 6 "Daim kab xev thiab reel" ntawm Cov Ntawv Teev Npe luv, los yog ntawm cov ntaub ntawv xav txog LED.Rau rau kev xa thiab xa tawm, cov reels tau ntim rau hauv lub tshuab nqus tsev ntim cov hnab qhuav (ua raws li MIL-STD 81705C, hom 1, chav kawm 1) ua ke nrog cov desiccants thiab amoisture qhia tau daim npav (Daim duab 2). Cov hlua thiab cov hnab qhuav tau teev tseg nrog cov khoom lag luam barcode daim ntawv lo (BPL). Daim ntawv lo no muaj cov ntaub ntawv ntawm lawv cov chaw tsim khoom (OSRAM Opto Semiconductors), qhov qhia txog keeb kwm, kev tsim khoom, tus lej lej, lej hnub tim, tus lej khoom thiab ntau npaum li cas.
BPL tseem hais txog ESD-, thiab chav kawm ua kom muaj dej noo, kev txhim kho kev tsim qauv, chav kawm ci ntsa iab thiab pab pawg ntawm LEDs raws li cov ntaub ntawv ntxiv yog xav tau. Feem ntau nws tau pom zoo los tshuaj xyuas lub hnab tom qab tau txais qhov kev puas tsuaj thiab ua tiav. Tsis muaj qhov, dents lossis tawg ntawm txhua yam uas yuav muaj nyob uas tuaj yeem cuam tshuam cov ntsiab lus. Txog kev khaws nws cov SMD LEDs ntim tsis tau qhuav ntim, OSRAM Opto Semiconductors qhia meej lub sijhawm khaws cia ntau tshaj 24 lub hlis (lub neej txee) nrog cov xwm txheej ib puag ncig tsis tshaj 40 ° C thiab cov av noo ntawm qhov siab tshaj. 90 % RH (txheeb ze cov av noo). Cov ntaub ntawv txuas ntxiv tuaj yeem nrhiav tau hauv ZVEI phau ntawv qhia rau kev khaws cia ntev ntawm cov khoom, sib dhos thiab khoom siv ("Leitfaden-Langzeitlagerfähigkeit vonBauelementen, Baugruppen und Geräten"). Nws yog qhov tsim nyog los tshuaj xyuas daim npav ntsuas dej noo nyob hauv ncaj qha tom qab qhib thiab ua ntej ua cov khoom. Qhov ntsuas qhia hloov xim ntawm xiav mus rau liab thaum qib sib xws ntawm cov dej noo ntau dua. Yog tias cov xim hloov pauv, cov ntaub ntawv tuav tseg tshwj xeeb (saib HIC thiab daim ntawv lo tiv taus dej noo-ML) yuav tsum tau pom thiab cov khoom yuav tsum tau rov qab qhuav yog tias tsim nyog (tseem saib JEDEC J-STD-033). Tom qab qhib lub hnab qhuav, LEDs muaj lub neej tshwj xeeb hauv pem teb nyob ntawm lawv cov qib kev ya raws (raws li JEDEC-STD-020). Lub neej hauv pem teb qhia meej lub sijhawm tom qab tshem tawm los ntawm lub hnab qhuav, khaws cia lossis ci ci thiab ua ntej rov siv dua
