Waqtigan xaadirka ah, wax organic gaar ahaan qalabka epoxy cusbi at qiimaha hooseeyo iyo farshaxanka baaluq qaybta ugu weli wax soo saarka PCB, iyo organic guddiga Bannaanka caadiga daabacan ka laba dhinacyada dhereg kulaylka iyo kaamerada Wehliyaha ballaarinta galmada tallaabadaas, ma buuxin karaan shuruudaha isdhexgalka circuit Semiconductor wanaajisaa wax unceasingly.Ceramic uu leeyahay qaab hirka sare wanaagsan iyo waxqabadka korontada, iyo leedahay conductivity kaamerada sare, xasiloonida kiimikada iyo xasiloonida kaamerada of muhashada organic sida aan haysan qaab wanaagsan, waa jiil cusub oo ballaaran circuit dhafan iyo xoogga module electronic ah material.Therefore baakadaha fiican, sannadihii la soo dhaafay, Guddiga dhoobada PCBayaa helay dareenka ballaaran iyo horumarinta degdeg ah.
guddiga circuit dhoobada substrate metallized dhoobada ku salaysan la guryaha kaamerada iyo korontada wanaagsan, waa nooc awood encapsulation LED, wax aad u fiican, iftiinka iyo guduud, ultraviolet (MCM) iyo waa gaar ah ugu haboon badan muhashada baakadaha chip sida lagala kulmo si toos ah (forgeetada) encapsulation chip Qaab-dhismeedka, isla mar ahaantaana, waxa kale oo loo isticmaali karaa sida guddiga circuit dhereg kulaylka of modules kale Semiconductor awood-awood sare, biiro hadda waaweyn, Relay, antenna warshadaha isgaarsiinta, filter, inverter qoraxda, iwm
Waqtigan xaadirka ah, horumarinta ee oolnimada sare, cufnaanta sare, iyo awood sare warshadaha ee LED gudaha iyo dibaddaba, waxa loo arki karaa ka 2017 si ay u 2018, guud ahaan LED horumarka qoyska degdeg ah, waxaa la sii kordhaya ee awoodda, horumarinta qaab ka xoogbadan, ee wax dhereg kulaylka ayaa noqday deg deg ah si ay u xaliyaan dhibaatada of dissipation.In guud ee kulaylka LED, nolosha LED hufnaan u Yeelaa Eebe iyo u-adeegidda hoos u kordha ee heerkulka kulanka, marka heerkulka isgoyska of 125 ℃ kor ku xusan, LED karo muuqan si xitaa failure.In in ay sii heerkulka LED heerkulka hooseeyo, conductivity kaamerada sare, iska caabin kulaylka hooseeyo iyo geedi socodka baakadaha macquul ah waa in loo qaatay si loo yareeyo iska caabin guud kaamerada of LED.
copper Epoxy muhashada u guntaday waa muhashada ugu ballaaran loo isticmaalo in packaging.It dhaqanka elektaroonik ah uu leeyahay saddex hawlood: taageero, tabinta iyo muuqaalada insulation.Its ugu muhiimsan waxay kala yihiin: qiimo jaban, iska caabin ah, qoyaan sare, cufnaanta hooseeyo, fududahay in geeddi-socodka, ay fududahay in ay ogaadaan micrographics circuit , ku haboon mass production.But iyadoo ay sabab u FR - 4 waxyaabaha salka waa cusbi epoxy, wax organic ah conductivity kaamerada hooseeyo, iska caabin heerkulka sare waa miskiin, sidaas FR - 4 ma qabsan karaan si ay cufnaanta sare, awoodda LED shuruudaha baakooyinka sare, guud ahaan kaliya loo isticmaalo baakadaha xoog yaraayeen LED.
Qalabka substrate dhoobada inta badan waa Alumina, nitride Aluminum, safayr, High Borosilicate Glass, iwm Marka la barbar dhigo qalabka kale ee substrate, substrate dhoobada leedahay sifooyinka soo socda ee guryaha farsamo, guryaha korontada iyo guryaha kaamerada:
(1) hantida Farsamada: xoog Farsamada noqon kartaa loo isticmaalaa sida taageerada qaybood, processing Good, sax cabbir sare, dusha siman, microcracks lahayn, foorarsiga, iwm
(2) hantida kulul: conductivity kaamerada The waa weyn yahay, Wehliyaha ku ballaarinta kaamerada waxaa kulan la Si iyo Gaas iyo qalabka kale ee chip, iyo iska caabin kulaylka waa wanaagsan yahay.
(3) guryaha korontada: joogta The dielectric waa yar yahay, khasaaraha dielectric waa yar yahay, iska caabin madhxiya iyo failure ningax yihiin sare, waxqabadka xasillooneyn hoos heerkulka sare iyo huurka badan, iyo isku halaynta waa heer sare ah.
(4) guryaha kale: xasiloonida kiimikada Good, ma nuugista qoyaan, Oil adkaysi iyo kiimikada adkaysta, Non-sun ah, qashin-free, warshadu hawada ray Alfa waa yar yahay, qaab-dhismeedka crystal ayaa ah mid deggan, iyo ma fududa in la beddelo in heerkulka range.Abundant agab cayriin.
Muddo dheer, Al2O3 waa wax substrate ugu muhiimsan ee awoodda sare packaging.But conductivity ah kaamerada of Al2O3 waa yar yahay, iyo Wehliyaha ku ballaarinta kaamerada ma u dhigma material.Therefore chip, marka la eego waxqabadka, qiimaha iyo ilaalinta deegaanka, this wax substrate ma noqon karo wax ugu fiican ee horumarinta qalabka-awood sare LED mustaqbalka. Nitride Aluminum dhoobada la conductivity sare kulaylka, xoog sare, heerka iska caabin sare, cufnaanta yar, si joogto ah dielectric yar yahay, oo aan sun ahayn, iyo sidoo kale guryaha u fiican sida Wehliyaha ballaarinta kaamerada of dhigma oo la Si ka, si tartiib ah u bedeli doona dhaqanka-awood sare wax substrate LED, noqdo mid ka mid ah waxyaabaha ugu substrate dhoobada mustaqbalka, bixinta weyn yahay 180W ~ 220w / MK, KingSong bixisaa loox wareeg daabacan dhoobada baahida PCB aad.
