Cov ntaub ntawv tseem ceeb hais txog LED Sawb Substrates

Thaum tshuaj ntsuam thiab sib piv homSaj zawg zog LED strips, ib qho feem ntau hais txog xim kub, LED ntau, thiab cov peev txheej tsim nyog rau qhov tau txais. Koj puas tau saib lub substrate ntawm uas cov leds yog affixed thiab tus yam uas lawv tau sib txuas? Niaj hnub no, peb yuav ua ib qho kev kuaj mob ntawm lubLED SawbSubstrate thiab cov me nyuam tsis saib xyuas cov yam ntxwv thiab cov khoom tau zoo tuaj yeem cuam tshuam LED Sawb kev ua haujlwm.
 

Dab tsi ua haujlwm ua lubLED Sawbsubstrate pab?

Lub LED Strip substrate ua haujlwm ua Circuit Court board thaum twg tus coj chips yog affixed. Lub substrate tsis yog ua haujlwm rau lub cev thiab txheej txheem teeb meem ntawm cov kab txaij coj mus los ntawm nws cov kev sib tw ua rau muaj kev sib tw tseem ceeb rau tshav kub dissipation.
 

Muaj pes tsawg leeg thiab lub moj khaum ntawm aSaj zawg zog LED Sawbsubstrate

Cov tseem ceeb tshaj plaws variant ntawm Led Sawb yog qhov saj tau ntau yam, muaj nyob rau hauv 16- ko taw reels. Lub substrate siv tau raug xa mus rau raws li yoog cov luam tawm cov cuab yeej siv hluav taws xob (FPC). Saj zawg hluav taws xob tau muaj nyob rau qee lub sijhawm thiab muaj tshwj xeeb rau cov ntawv thov koom nrog kev txiav txim siab lossis nkhaus.
Saj zawg zog LED stripsQib tsim cov thev naus laus zis thiab ua haujlwm zoo li lub hauv paus zoo li cov yam ntxwv zoo li qub substrate. Feem ntau, polyimide (pi) yog cov khoom siv uas nyiam.
Polyimides muab cov kev zam tshwj xeeb thiab cua sov ua thaum tswj cov khoom siv yooj yim. Yog li ntawd, cov khoom siv polyimide yog qhov tseem ceeb rau kev ua kom pom tseeb ob qho tib si thiab cov qauv kev ncaj ncees hauv cov txheej txheem LED.
Lub hauv paus ntawm tooj liab ntawm tooj liab yog tsim, ua raws li ntawm ib txheej tub ntxhais ntawm polyimide polyimide polyimide, ntawm ob sab nrog cov nplaum tshwj xeeb. Cov khaubncaws sab nrauv sab nrauv sab nrauv yog feem ntau hu ua "Coverellay" thiab muaj nyob rau ntau xim. Dawb yog feem ntau xaiv los ua kom zoo dua kev xav.
Qhov peb txheej ntawm polyimide kev tiv thaiv thiab cov qauv kev ruaj ntseg rau cov txheej tooj liab. Qee qhov chaw me me yuav tsum tau raug tooj liab los pab txhawb hluav taws xob rau cov leds thiab lwm yam.
Ib txheej ntawm ob-sided daim kab xev yog thaum kawg affixed mus rau tom qab ntawm lub led sawb. Qhov feem ntau siv siv ob npaug rau cov nplaum rau lub hom phiaj no yog 3M 200MP.
 

Tus tooj liab loj ntawm tooj liab yog qhov tseem ceeb.

Xaiv cov tooj liab yog qhov tseem ceeb hauv ib qho hluav taws xob hluav taws xob. Qhov zoo thiab huv dawb ntawm tooj liab siv hauv hluav taws xob hluav taws xob yog feem ntau qauv; Tsis tau, nws tuab yuav sib txawv. OUCCE (OZ), Thaum ntsuas qhov hnyav, yog ib txwm ua haujlwm rau kev kho tus tooj liab, hauv OUCCES, yuav tsum tau ua kom muaj qhov tuab tuab dua ib qho tuab ntawm ib qho tuab.
Thaum xaiv ibLED Sawb Teeb, xav txog cov tuab ntawm tooj liab. Rau high fais fab coj strips, peb pom zoo tsawg kawg ntawm 2. {}}}} {}} Igces lossis ntau dua. Tag nrho lwm yam yog sib npaug, tuab tooj liab yog qhov zoo dua rau cov laj thawj hauv qab no:
Ntau dua tooj liab thickness pab hluav taws xob conduction nyob rau hauv lub LED Sawb lub voj voog. Cov tooj liab tsis txaus yuav ua rau muaj kev cuam tshuam hluav taws xob tsis kam thiab ua kom kub ua rau hluav taws xob poob thiab ntxov ua tsis tau.
Qoos tooj liab tuab ua rau muaj kev cuam tshuam sov sai sai. Qhov ntau nrawm nrawm los ntawm LEDs yog dissipated rau hauv ib puag ncig ib puag ncig, qhov zoo dua cov LEDs yuav ua haujlwm thiab nyiaj dhau. Tooj liab yog tus thawj coj thermal no; Yog li, cov tuab ntau ntxiv yuav ua rau muaj kev cuam tshuam ntau ntxiv rau qhov tsis txaus siab ntawm cov leds.
 

Tsis tawvLED stripsUa kom muaj kev nthuav dav tsis txaus.

Thawj qhov tsis zoo ntawm kev hloov pauv tau LED Sawb cov txheej txheem yog lawv qhov kev ua tau zoo ntawm kev ua haujlwm thermal. Lub thermal conductivity ntawm kapton (polyimide) yog {{0}}}}}}}}}}}}}}}}
Hauv kev sib piv, txhuas thiab tooj liab ua pov thawj qhov tseem ceeb ntawm 2}}}}}}} Thaum tsim nyog ua nrog thermal vias, lub thermal conductivity ntawm ob-txheej pcb tuaj yeem raug thauj mus los rau cov tooj liab tam sim ntawd.
Ob peb ntsuas tuaj yeem ua; Txawm li cas los xij, feem ntau ntawmLED SawbCov khoom lag luam tau tsim los tiv thaiv kev kub ntxhov. Qhov tsis zoo yog tias cov hlua coj tau coj mus ua haujlwm hauv lawv lub peev xwm los ua haujlwm ntawm kev sib txuas siab dua, vim cov cua sov dissipation tsis txaus. Qhov no tuaj yeem piv rau lub cav Ferrari uas tsis tuaj yeem ua haujlwm ntawm nws lub peev xwm tshaj plaws vim yog lub zog hluav taws xob nrog kev txuag nyiaj.
