Cov khoom yog ib qhoLED Yooj Yim Lub Teeb Sawbnrog txoj hlua-zoo li daim duab. Tsis txhob cia li xav txog tus nqi thaum yuav cov hlua coj coj mus. Ua ntej koj xaiv cov pheej yig tshaj plaws coj sawb, peb taug kev koj los ntawm kev ntsuam xyuas meej ntawm yim yam hauv qab no.
Saj zawg zog sawb chips rau coj
Tej daim tuaj hauv ob hom Taiwanese thiab ntau yam, nrog rau lwm haiv neeg (xws li Asmeskas, Japanese, German, thiab lwm yam). Muaj ib tug tseem ceeb nqi sib txawv ntawm daim tawv nyias. Thaum lub sijhawm, Taiwan ua cov chips pheej yig tshaj, thaum United States ua cov nqi ntau tshaj, ua raws li Nyiv thiab Lub Tebchaws Yelemees. Taiwan tsab Chips yog tam sim no siv los tsim cov khoom siv coj hloov tau uas muaj nyob rau ntawm kev ua lag luam; Lawv tsim nyog tus nqi thiab muab kev ua tau zoo heev. Dab tsi nti yog qhov no, tau kawg? Dab tsi yog qhov tshwm sim? Paub txog ua ntej koj yuav.
LED pob suav nrog cov pob mov yooj yim thiab cov khoom lag luam resin. Txij li txhua tsav txhua yam yog tib yam thiab cov cua sov dissipation yog ib tug neeg txom nyem me me, lub pob khoom cob qhia yog qhov tsim nyog. Vim nws cov kev ua kom sov siab dua, Silicone Encapsulation yog qee qhov nqi ntau dua li Resin Encapsulation.
Kev sib xws ntawm LED xim
Muaj ntau pua lub tsev ntim khoom hauv tsev thaum lub sijhawm. Ntawm chav kawm, muaj cov txiaj ntsig zoo thiab qhov tsis zoo ib yam nkaus. Nws yog qhov nyuaj kom ua tau zoo txij li ntau cov neeg nqa khoom me me tsis muaj cov khoom sib cais xim, yog li lawv tsis cais cov xim lossis tsis xa lawv tawm. Lub LED kev ua pov thawj tsis zoo xim thiab tsis muaj xim sib cais. Tom qab tau raug ntsia rau ntawm LED hloov lub teeb ci ntsa iab, cov teeb pom kev zoo tsis zoo heev. Lawm, muaj tus nqi tseem ceeb.
LED xim
Ntau yam tsis zoo thiab tus nqi. Liab, daj, xiav, thiab lwm cov xim tau yooj yim cais thiab muaj ntau dua li tsawg dua li dawb thiab ntsuab, uas nyuaj rau kev sib phim thiab cais. Vim xim sib piv, cov xim tshwj xeeb zoo li ntshav thiab xim av yog cov nqi zog.
Qhov cuam tshuam ntawm LED Vuam
Ob lub tshuab thiab tib neeg vuam yog siv los tsim cov LED hloov tau lub teeb tag nrho cov teeb tsa.
1) soldering los ntawm txhais tes {1}}} siv cov txheej txheem yooj yim tshaj plaws thiab cov hlau soldering. Cov khoom tsim siv cov qauv no muaj qhov tsis txaus ntseeg saib (flux residue, blux cov pob qij txha, hlawv cov khoom tiv thaiv butter, thiab lwm yam. Lub ci / ci tsis kaj phenomena yog tshwm sim los ntawm kev rhuav tshem ntawm ob peb tus coj chips.
2) tshuab soldering --- showing siv cov ntsej muag zoo, thiab nws kuj tiv thaiv hluav taws xob zoo li cas los ntawm kev ua kom lub nti. Ib qho ntxiv, cov leds 'kev taw qhia thiab kev tso chaw muaj kev txaus nyiam dua. Qhov no yog pom meej tam sim ntawd los ntawm saib.
FPC Cov Ntsiab Lus
FPC los hauv ob hom: tooj liab plated thiab dov tooj liab. Txawm hais tias tooj liab plating yog tus nqi ntau dua, nws tseem tsawg dua. Dov tooj liab tiv thaiv tooj liab-plated pads los ntawm kev swb thaum khoov. Cov neeg yuav khoom xaiv ntawm FPC cov khoom siv yuav tsum siv yog kev sib txuas yog raws li kev siv kev siv. Txij liBenwei LedTam sim no siv tsuas yog dov tooj liab rau nws FPC, qhov tshwm sim coj hloov lub teeb pom kev zoo kuj tseem muaj ntau dua cov khoom muag-tiv taus. Puas yog cov ntawv pov thawj lossis FPC ib puag ncig? Muaj ntawv pov thawj thiab patented leds, txawm li cas los xij lawv muaj nqi ntau dua li cov uas tsis muaj patented. Puas yog tus coj muaj patents, thiab lwm yam?
Ci ntsa iab ntawm LEDs
Viesting ci ci tau hloov tus nqi sib txawv, thiab lub teeb ci ntsa iab thiab lub teeb ci siab tau sib txawv. Txhawm rau nrhiav kom pom peb cov khoom, koj yuav tsum yog li paub dab tsi ntawm qhov ci uas koj xav tau ua ntej kev yuav khoom.
LED Qhov Ntev
Tus nqi ntawm LEDs txawv nyob ntawm lawv qhov loj me thiab nta. Piv txwv li, muaj tus nqi tseem ceeb ntawm 0603 thiab 1210 (3528) coj, thiab 5050 tus qauv coj yog ib qib ntxiv.
Nco tseg: electrostatic puas los ntawm LED hloov lub teeb lub teeb pom kev zoo li, yog li kev tiv thaiv LED, yog li cov LED hloov hluav taws xob, ua rau lub teeb hloov hluav taws xob Nov yog ib qho tshwm sim uas tsis tuaj yeem ua tau zoo uas tsis tuaj yeem rov qab tau. Qhov teeb meem yog tias tom qab ib ntus, ob peb ntawm cov chips tshem tawm teeb pom kev zoo, tawm hauv cov khoom siv dub uas tus neeg tuaj yeem pom lawv. Kev tuag lub teeb, ib qho tshwm sim tshwm sim hauv kev lag luam, yog qhov teeb meem tseem ceeb no.
