Xirmada korantada ee PCB waxay u shaqeysaa sida gudbiyaha kulaylka iyo hawada, iyo kuleylka kuleylka ayaa door muhiim ah ka ciyaara kuleylka kuleylka ee LED.DPC ceramic PCB waxay muujineysaa tartan xooggan oo ka mid ah alaabooyin badan oo elektaroonig ah oo baakadaha elektiroonigga ah oo leh waxqabadkiisa ugu fiican iyo si tartiib tartiib ah hoos u dhigaya qiimaha. , taas oo ah isbeddelka awoodda horumarinta baakadaha LED mustaqbalka.Horumarinta sayniska iyo tignoolajiyada iyo soo ifbaxa hababka diyaarinta cusub, qalabka dhoobada kulaylka sare leh ayaa leh rajooyin codsi oo ballaadhan sida qalabka PCB ee cusub ee baakadaha elektiroonigga ah.
Iyadoo horumarinta joogtada ah ee awoodda wax-gelinta ee chips LED, kulaylka weyn ee ay dhaliso awoodda weyn ee daadinta ayaa soo bandhigtay shuruudo cusub oo sarreeya oo loogu talagalay alaabta baakadaha LED.Kanaalka kuleylka LED-ka, xirmooyinka PCB-ga ayaa ah isku xirka muhiimka ah ee isku xira waddooyinka kuleylka gudaha iyo dibadda, wuxuuna leeyahay hawlaha kanaalka kuleylka kuleylka, isku xirka wareegga iyo taageerada jireed ee chip.Wixii awood sare lehAlaabta LED, PCB-ga baakadu waxay u baahan tahay dahaar sare oo koronto ah, kulaylka sareynta, iyo fidinta kulaylka oo la mid ah chip-ka.
Laakin xirmo-ku-saleysan PCB: kharashka badan ee taageerada weli way adagtahay in la shaaciyo.EMC iyo SMC waxay leeyihiin shuruudo sare oo ku saabsan qalabka wax lagu dhejiyo.Qiimaha khadka wax-soo-saarka isku-buufintu wuxuu ku dhow yahay 10 milyan yuan, wali way adag tahay in lagu shaaciyo miisaan ballaaran.Qalabka LED-ka ee SMD ee soo baxay sanadihii ugu dambeeyay guud ahaan waxay adeegsadaan qalabyo balaastiig ah oo heerkul sarreeya oo wax laga beddelay, iyadoo la adeegsanayo resin PPA sida alaab cayriin ah, oo lagu daro buuxinta wax laga beddelay si kor loogu qaado qaar ka mid ah sifooyinka jirka iyo kiimikaad ee alaabta ceeriin ee PPA, si agabka PPA ay aad ugu habboon yihiin qaabaynta irbado.Iyo isticmaalka SMD LED bracket.Dareenka kulaylka caagga PPA waa mid aad u hooseeya, iyo kuleylkeeda
Burburinta waxaa inta badan lagu fuliyaa qaabka macdanta rasaasta.Awoodda kuleylka kuleylka ayaa xaddidan, waxayna ku habboon tahay oo kaliya baakadaha LED-ka hooseeya.
Birta Muhiimka ah ee Daabacan Guddiyada Wareegga: Nidaamyada Wax Soo Saarka ee Kakan iyo Codsiyada Dhaqan-galka yar.Habka wax-soo-saarka ee PCB-ku-salaysan aluminiumku waa mid adag qiimuhuna waa sarreeyaa.Isku-xidhka balaadhinta kulaylka ee aluminiumku aad ayuu uga duwan yahay kan qalabka chip-ka, waxaana marar dhif ah loo adeegsadaa codsiyada la taaban karo.Inta badan xirmooyinka LED-ga awoodda sare leh waxay isticmaalaan PCB-ga noocaan ah, qiimuhuna wuxuu u dhexeeyaa qiimaha dhexe iyo kan sare.Way u fiican tahayLED MINI bandhigay.PCB-ga tamarta sare ee LED-ka kuleylka hadda jira ee wax soo saarku wuxuu leeyahay koronto kuleyl ah oo aad u hooseeya oo lakabka daboolaya, iyo jiritaanka lakabka dahaadhka, uma adkeysan karo alxanka heerkulka sare, kaas oo xaddidaya hagaajinta qaab dhismeedka xirmada waana aan ku habboonayn kuleylka LED-ka.
Baakadaha Silicon-ku-salaysan PCB: caqabadaha hortaagan, heerka wax-soosaarku waxa uu ka yar yahay 60%.Qalabka Silicon-ku-saleysan waxaa loo isticmaalaa sidii tikniyoolajiyadda PCB ee baakadaha LED, taas oo loo isticmaalowarshadaha LEDwarshadaha semiconductors.Dhaqdhaqaaqa kulaylka iyo sifooyinka fidinta kulaylka ee PCB-yada silikoon ku salaysan waxay muujinayaan in silikoonku yahay baakadaha ku habboon LED-yada.Dhaqdhaqaaqa kulaylka
Silikoonku waa 140W/m·K.Marka loo isticmaalo baakadaha LED-ka, iska caabbinta kulaylka ay sababto waa 0.66K / W oo keliya;iyo walxaha silikoon-ku-salaysan ayaa si weyn loogu isticmaalay hababka wax-soo-saarka semiconductor iyo goobaha baakadaha ee la xidhiidha, oo ku lug leh qalabka iyo qalabka la xidhiidha.aad u bislaaday.Sidaa darteed, haddii silicon laga sameeyo xirmo LED PCB, wax soo saarka ballaaran waa sahlan tahay.Si kastaba ha ahaatee, weli waxaa jira dhibaatooyin farsamo oo badan oo ku jira baakada PCB ee silikoon LED.Tusaale ahaan, marka la eego maaddooyinka, qalabka silikon si fudud ayaa loo jajabiyaa, sidoo kale waxaa jira dhibaato xoogga farsamada.Marka la eego qaab-dhismeedka, in kasta oo silikoonku yahay kaari kuleyl ah oo aad u fiican, waxay leedahay dahaar liidata waana in la dahaadhaa.Intaa waxaa dheer, lakabka birta ah wuxuu u baahan yahay in lagu diyaariyo sputtering oo lagu daray koronto, iyo daloolka korantada wuxuu u baahan yahay in lagu diyaariyo etching.Guud ahaan, diyaarinta lakabyada dahaarka, lakabyada birta, iyo fiisooyinka dhammaan waxay wajahaan caqabado, iyo wax-soo-saarku maaha mid sarreeya.
Xidhmada dhoobada PCB: Hagaajinta waxtarka kulaylka si loola kulmoLED-Awood sareDalabkaIyada oo leh matrix dhoobo ah oo kuleyl ah oo sarreeya, waxtarka kuleylka kuleylka ayaa si weyn loo wanaajiyay, waana badeecada ugu habboon ee baahida horumarinta tamarta sare iyo LEDS yar yar.PCBS Ceramic waxay leedahay qalab cusub oo kulaylka iyo qaabab cusub oo gudaha ah, kuwaas oo ka kooban cilladaha birta aluminium PCBS, taas oo kor u qaadaysa guud ahaan saamaynta kulaylka PCB.Waxyaabaha dhoobada ah ee loo isticmaali karo PCB-da kulaylka, BEO waxay leedahay koror kuleyl sare leh, laakiin isku-darka fidinta tooska ah ayaa aad uga duwan kan silikoon, waana sun inta lagu jiro wax soo saarka, taas oo xaddidaysa codsigeeda;BN waxa uu leeyahay waxqabad dhammaystiran oo wanaagsan, laakiin PCB ahaan maaddo ma laha faa'iidooyin muuqda oo qaali ah, oo hadda ku jira cilmi-baadhis iyo dhiirrigelin;carbide silicon waxa uu leeyahay xoog sare iyo conductivity kaamerada sare, laakiin ay iska caabin ah iyo dielectric u adkeysan danab yar yihiin, iyo bond ka dib metallization waa mid aan degganayn, taas oo keeni doonta Isbedelada conductivity kulaylka iyo dielectric joogto ah waa in aan loo isticmaalin sida insulating qalabka PCB.In kasta oo al2O3 substrate dhoobada uu hadda yahay midka ugu soo-saarka badan uguna ballaadhan ee loo isticmaalo substrate dhoobada, sababta oo ah is-ballaadhintiisa kulaylka ka sarreeya kan Si single crystal, Al2O3 substrate dhoobada kuma habboona soo noqnoqoshada sare, awood sare, isku-dhafan ultra-weyn. wareegyada.loo isticmaalo in. A1N crystal leeyahay conductivity kaamerada sare oo waxaa loo arkaa in ay tahay wax ku haboon PCBS jiilka soo socda semiconductor iyo baakadaha.
AlN ceramic PCB si weyn baa loo darsay oo si tartiib tartiib ah ayaa loo horumariyay ilaa 1990-meeyadii.Hadda waxaa guud ahaan loo arkaa inay tahay alaab elektaroonik ah oo baakadaha dhoobada ah.Waxtarka kuleylka AlN ceramic PCB waa in ka badan 7 jeer ka Al2O3.Faa'iidada kuleylka kulaylka ee AlN ceramic PCB oo lagu dabaqay LED-yada awoodda sare leh waa mid cajiib ah, taasoo si weyn u wanaajineysa nolosha adeegga LED-yada.DPC ceramic PCB sidoo kale waxaa loo yaqaannaa looxa dhoobada ah ee tooska ah.Alaabooyinka DPC waxay leeyihiin sifooyinka saxnaanta wareegga sare iyo flatness dusha sare.Waa badeeco isdhaafsi ah oo ku habboon baahida horumarinta ee tamarta sare, LED-yada yaryar.
