Txhuas raws Circuit Court board

Aluminium substrate Circuit Court, tseem hu ua Circuit board board, yog ib qho tshwj xeeb cov hlau clad tooj liab phaj nrog zoo thermal conductivity, hluav taws xob rwb thaiv tsev kev ua tau zoo thiab kev siv tshuab ua haujlwm. Nws yog ua los ntawm cov ntawv ci tooj liab, txheej rwb thaiv tsev thermal thiab hlau txheej. Nws cov qauv tau muab faib ua peb txheej: Cov txheej puag ncig: tooj liab clad sib npaug rau cov zoo tib yam PCB, Circuit tooj liab ntawv ci tuab yog 1oz txog 10oz. Rwb thaiv tsev txheej: rwb thaiv tsev txheej txheej yog txheej txheej txheej txheej txheej rwb thaiv tsev thermal uas tsis tshua muaj kev ua haujlwm thermal. Thickness: 0.003 "rau 0.006 ″ nti yog cov tub ntxhais thev naus laus zis clamin laminate, uas yog UL muaj ntawv pov thawj. Substrate: hlau txaij txheej, feem ntau txhuas lossis tooj liab substrate. 

Aluminium clad laminate thiab tsoos epoxy iav daim ntaub laminate, thiab lwm yam., Hauv cov txheej txheem hauv Circuit Court, yuav tsum muaj lub peev xwm loj-nqa tam sim no, yog li cov ntawv tuab tooj liab nrog cov tuab 35um ~ 280um yuav tsum siv. Thermal rwb thaiv tsev txheej yog lub hauv paus thev naus laus zis ntawm txhuas pawg tswj hwm Circuit Court. Nws yog feem ntau ua los ntawm cov polymer tshwj xeeb uas muaj cov ntoo tshwj xeeb. Nws muaj cov ua haujlwm thermal me me, zoo heev viscoelastic muaj peev xwm, thermal laus ua hauj, thiab tuaj yeem tiv taus cov neeg kho tshuab thiab thermal kev ntxhov siab. Cov txheej txheem thermal rwb thaiv tsev ntawm kev ua haujlwm siab aluminium ua raws li cov laug cam Circuit Court, xws li IMS-H01, IMS-H02 thiab LED-0601, Nws siv cov thev naus laus zis, kom nws muaj cov thermal conductivity zoo thiab siab zog hluav taws xob rwb thaiv tsev ua haujlwm. 

Hlau puag yog qhov kev txhawb nqa ntawm cov txhuas txheej uas yuav tsum muaj cov siab ua cov siab zoo. Feem ntau, nws yog txhuas phaj, tab sis phaj tooj liab kuj tseem siv tau (tooj liab phaj tuaj yeem ua tau zoo dua thermal conductivity), uas tsim nyog rau kev ua kom drilling, xuas nrig ntaus thiab txiab, txiav thiab lwm cov pa ua cov tshuab. Piv nrog rau lwm cov ntaub ntawv, aluminium substrate PCB muaj txiaj ntsig tsis zoo. Haum rau SMT txheej txheem ntawm lub hwj chim module nto mount. Tsis muaj radiator, txo ntau ntim, zoo heev tshav kub dissipation nyhuv, zoo rwb thaiv tsev thiab cov khoom siv kho tshuab. 

Ib qho khoom siv tsis yog tsuas yog pheej yig, kev kub hnyiab tawm thiab zoo rau cov PCB substrate. Feem ntau, xav txog tus nqi thiab kev ua haujlwm, txhuas phaj yog qhov kev xaiv zoo tshaj plaws rau qhov no siv PCB pawg thawj coj saib. Muaj cov phaj txhuas yog 6061,5052,1060, thiab lwm yam tooj liab, hlau tsis xeb, hlau thiab silicon steel kuj tseem siv tau yog tias cov cua sov ua ntau dua, cov cuab yeej siv zog, cov khoom siv hluav taws xob thiab lwm yam khoom tshwj xeeb. Nws feem ntau pom hauv LED teeb pom kev zoo cov khoom, muaj qhov zoo thiab tsis zoo.

Lub dawb sab yog welded LED pins, thaum lwm sab qhia tus thawj xim ntawm txhuas. Feem ntau, kev siv tshuaj pleev ib ce thermal yuav raug siv thiab tom qab ntawd tiv tauj nrog cov ntu thermal conductive. Piv nrog rau kev ua kom ib txwm FR-4, aluminium substrate tuaj yeem txo qhov thermal tsis kam mus rau qhov tsawg kawg nkaus, kom cov aluminium substrate muaj cov thermal conductivity zoo. Piv nrog ceramic substrate, nws cov khoom siv kho tshuab yog qhov zoo heev. Ntxiv rau qhov kev ua kom zoo cua sov ua kom zoo, aluminium substrate muaj cov txiaj ntsig zoo li nram no: Ua raws nrog RoHS ib puag ncig kev xav tau ntau dua rau cov txheej txheem SMT Ntau dua tam sim no nqa lub peev xwm Nyob hauv tus qauv tsim qauv, cov thermal diffusion kho tau zoo heev, thiaj li ua kom txo qis kev ua haujlwm kub. ntawm qhov hloov pauv, txuas lub neej ntev kev pab cuam, thiab txhim kho lub zog kaw thiab kev ntseeg tau. Txo txo ​​kev sib dhos ntawm radiators thiab lwm yam khoom siv (suav nrog thermal interface

cov ntaub ntawv), txo qhov ntim ntawm cov khoom lag luam, thiab txo nqi kho vajtse thiab sib dhos; Txhim kho txoj kev sib txuas ua ke ntawm lub zog hluav taws xob thiab tswj Circuit Court; Hloov cov pob zeb ua kom puas yooj yim substrate rau cov cuab yeej zoo dua. Ib qho ntawm qhov loj tshaj ntawm cov txhuas txheej dua hla cov pa FR-4 cov paib yog tias lawv tuaj yeem nqa hluav taws xob ntau dua. Zoo li FR-4, ntawv ci tooj liab yog siv los ua cov txheej xov hlau rau kev sib txuas. Piv nrog cov tsoos FR-4, aluminium substrate yog tib yam tuab thiab cov kab dav thiab tuaj yeem nqa dua tam sim no. Lub hauv paus thev naus laus zis ntawm aluminium substrate yog qhov nruab nrab insulating txheej khoom, uas feem ntau ua cov haujlwm ntawm kev ua tiav, rwb thaiv tsev thiab kev ua haujlwm kub. Aluminium substrate rwb thaiv tsev txheej yog qhov loj tshaj plaws ntawm cov cua sov hauv hluav taws xob qauv qauv. 

Qhov zoo dua qhov thermal conductivity ntawm lub rwb thaiv tsev txheej yog, ntau qhov tsim nyog nws yog rau qhov sib txawv ntawm cov cua sov tsim tawm thaum lub sijhawm ua haujlwm ntawm lub cuab yeej, thiab qis dua qhov ua haujlwm kub ntawm lub cuab yeej, thiaj li ua kom lub zog thauj khoom ntawm lub module. , txo qhov ntim, txuas ntxiv lub neej, thiab nce lub zog txuas. Ntxiv nrog rau qhov txaus siab rau qhov ua tau zoo thermal conductivity, nws kuj yuav tsum muaj lub zog qhov ntsuas hluav taws xob muaj zog.

 

Kev faib tawm ntawm cov txhuas substrates

Aluminium clad laminates tau muab faib ua peb pawg:

Universal txhuas-puag tooj liab-clad phaj, rwb thaiv tsev txheej yog tsim ntawm epoxy iav daim ntaub sib khi ntawv;

Siab kub dissipation aluminium clad nrog insulating txheej ua los ntawm epoxy resin lossis lwm yam khoom siv nrog lub siab thermal conductivity;

Aluminium clad phaj rau qhov ntau ntawm Circuit Court, rwb thaiv tsev txheej yog tsim ntawm

polyolefin resin los yog polyimide resin iav ntaub daim ntaub.
