Imbaraga LED yamashanyarazi PCB ikora nk'itwara ry'ubushyuhe n'umuyaga, kandi ubushyuhe bwacyo bugira uruhare runini mugukwirakwiza ubushyuhe bwa LED.DPC ceramic PCB yerekana guhangana cyane mubikoresho byinshi bipakira ibikoresho bya elegitoronike nibikorwa byayo byiza kandi bikagabanuka buhoro buhoro igiciro , niyo nzira yimbaraga za LED gupakira iterambere mugihe kizaza.Hamwe niterambere ryubumenyi nubuhanga hamwe no kugaragara muburyo bushya bwo kwitegura, ibikoresho byinshi byubushyuhe bwumuriro ceramic bifite ibyerekezo byinshi byo gukoresha nkibikoresho bishya bya elegitoroniki bipakira ibikoresho bya PCB.
Hamwe nogukomeza kunoza imbaraga zinjiza za chipi ya LED, ubushyuhe bunini butangwa nimbaraga nini zo gukwirakwiza bwashyize imbere ibisabwa bishya kandi bisabwa kubikoresho byo gupakira LED.Mu muyoboro wa LED wo gukwirakwiza ubushyuhe, gupakira PCB nurufunguzo rwingenzi ruhuza inzira zo gukwirakwiza ubushyuhe bwimbere n’imbere, kandi bufite imikorere yumuyoboro wo gukwirakwiza ubushyuhe, guhuza imirongo hamwe nubufasha bwumubiri kuri chip.Kubububasha bukomeyeLED ibicuruzwa, gupakira PCB isaba amashanyarazi menshi, amashanyarazi menshi, hamwe na coefficente yo kwagura ubushyuhe ihuye na chip.
Ariko resin ishingiye kuri PCB: igiciro kinini cyo gutera inkunga biracyagoye kumenyekana.EMC na SMC bifite ibisabwa byinshi kubikoresho byo guhunika.Igiciro cyumubyigano wo guhuza ibicuruzwa bigera kuri miriyoni 10, kandi biracyagoye kubimenyekanisha murwego runini.SMD LED imirongo yagaragaye mumyaka yashize muri rusange ikoresha ibikoresho bya pulasitiki yubushyuhe bwo hejuru yubushyuhe bwo hejuru, ikoresha resin ya PPA nkibikoresho fatizo, ikongeramo ibyuzuye byahinduwe kugirango izamure ibintu bimwe na bimwe bifatika na chimique byibikoresho fatizo bya PPA, kugirango ibikoresho bya PPA bibe byiza cyane gushushanya inshinge.Kandi ikoreshwa rya SMD LED bracket.Amashanyarazi yubushyuhe bwa plastike ya PPA ni make cyane, nubushyuhe bwayo
gusaranganya bikorwa cyane cyane binyuze mucyuma kiyobora.Ubushobozi bwo gukwirakwiza ubushyuhe ni buke, kandi burakwiriye gusa kubipfunyika buke bwa LED.
Ibyuma Byibanze Byacapwe Kumuzunguruko: Inzira Zikora Inganda hamwe na Porogaramu Ntoya.Gutunganya no gukora progaramu ya aluminium ishingiye kuri PCB iragoye kandi igiciro ni kinini.Coefficente yo kwagura ubushyuhe bwa aluminiyumu iratandukanye cyane niyibikoresho bya chip, kandi ntibikoreshwa gake mubikorwa bifatika.Ibyinshi mumashanyarazi menshi LED yamashanyarazi akoresha ubu bwoko bwa PCB, kandi igiciro kiri hagati yikiguzi cyo hejuru nigiciro kinini.Nibyiza kuriLED MINI yerekana.Kugeza ubu ingufu nyinshi za LED zikwirakwiza ubushyuhe PCB mu musaruro zifite ubushyuhe buke cyane bw’ubushyuhe bw’urwego rukingira, kandi kubera ko hariho urwego rukingira, ntirushobora kwihanganira kugurisha ubushyuhe bwo hejuru, bigabanya uburyo bwiza bwo gupakira kandi ni ntabwo bifasha LED gukwirakwiza.
Ibikoresho bipakira bishingiye kuri silicon PCB: guhura nibibazo, igipimo cy'umusaruro kiri munsi ya 60%. PCBs ishingiye kuri silikoni ihura nibibazo mugutegura insulasiyo, ibyuma, na vias, kandi umusaruro nturenga 60%.Ibikoresho bishingiye kuri silikoni bikoreshwa nka LED ipakira PCB tekinoroji, ikoreshwa muriInganda LEDmu nganda ziciriritse.Ubushyuhe bwumuriro hamwe nubushyuhe bwo kwagura ubushyuhe bwa PCBs ishingiye kuri silicon yerekana ko silikoni ari ibikoresho byiza byo gupakira kuri LED.Amashanyarazi
ya silicon ni 140W / m · K.Iyo ikoreshejwe mubipfunyika LED, kurwanya ubushyuhe bwatewe nayo ni 0.66K / W gusa;n'ibikoresho bishingiye kuri silikoni byakoreshejwe cyane mubikorwa byo gukora semiconductor hamwe nibikorwa byo gupakira bijyanye, birimo ibikoresho nibikoresho bijyanye.akuze rwose.Kubwibyo, niba silicon ikozwe muri LED pack PCB, umusaruro mwinshi biroroshye.Ariko, haracyari ibibazo byinshi bya tekiniki mubikoresho bya LED silicon PCB.Kurugero, kubijyanye nibikoresho, ibikoresho bya silicon biravunika byoroshye, kandi hariho ikibazo nimbaraga zuburyo.Kubijyanye nimiterere, nubwo silicon numuyoboro mwiza wumuriro, ifite insulasiyo mbi kandi igomba kuba oxyde kandi ikingirwa.Byongeye kandi, icyuma kigomba gutegurwa no gusohora hamwe na electroplating, kandi umwobo uyobora ugomba gutegurwa no gutobora.Muri rusange, gutegura ibice byabigenewe, ibyuma, na vias byose bihura nibibazo, kandi umusaruro ntabwo ari mwinshi.
Ceramic Package PCB: Kunoza Ubushyuhe bwo Gukwirakwiza GuhuraLED-Imbaraga nyinshiIbisabwa.Hamwe na matrike ya ceramic yumuriro mwinshi, uburyo bwo gukwirakwiza ubushyuhe bwateye imbere kuburyo bugaragara, kandi nigicuruzwa gikwiranye niterambere ryingufu zikenewe hamwe nubunini buto LEDS.Ceramic PCBS ifite ibikoresho bishya byubushyuhe bwumuriro nuburyo bushya bwimbere, bugizwe nubusembwa bwicyuma cya aluminium PCBS, bityo bikazamura ingaruka rusange yo gukwirakwiza ubushyuhe bwa PCB.Mubikoresho byubutaka bushobora gukoreshwa mugukwirakwiza ubushyuhe PCB, BEO ifite ubushyuhe bwinshi, ariko coefficente yayo yo kwagura umurongo itandukanye cyane na silikoni, kandi ni uburozi mugihe cyo kuyikora, igabanya ikoreshwa ryayo bwite;BN ifite imikorere myiza yuzuye, ariko nka PCB Ibikoresho nta nyungu zidasanzwe kandi bihenze, kandi ubu biri mubushakashatsi no kuzamura gusa;karubide ya silicon ifite imbaraga nyinshi nubushyuhe bwo hejuru bwumuriro, ariko kurwanya kwayo hamwe na dielectric kwihanganira voltage ni bike, kandi guhuza nyuma ya metallisation ntibihinduka, bizatera Impinduka mumashanyarazi yumuriro hamwe na dielectric ntagomba gukoreshwa nkibikoresho byo gupakira ibikoresho bya PCB.Nubwo ubu Al2O3 ceramic substrate isanzwe ikorwa cyane kandi ikoreshwa cyane muri ceramic substrate, bitewe nuburinganire bwayo bwo kwagura ubushyuhe burenze ubwa Si kristu imwe, Al2O3 ceramic substrate ntabwo ikwiranye numurongo mwinshi, imbaraga nyinshi, ultra-nini nini nini cyane imirongo.ikoreshwa.
AlN ceramic PCB yizwe cyane kandi igenda itera imbere kuva 1990.Kugeza ubu muri rusange bifatwa nkibikoresho bitanga ibikoresho bya elegitoroniki ceramic.Ubushyuhe bwo gukwirakwiza ubushyuhe bwa AlN ceramic PCB bukubye inshuro 7 ubwa Al2O3.Inyungu zo gukwirakwiza ubushyuhe bwa AlN ceramic PCB zikoreshwa kuri LED zifite ingufu nyinshi ziratangaje, bityo kuzamura ubuzima bwa serivisi za LED.DPC ceramic PCB izwi kandi nkibibaho bikozwe mu muringa.Ibicuruzwa bya DPC bifite ibiranga umuzenguruko muremure hamwe nuburinganire buringaniye.Nibicuruzwa byambukiranya ibisekuruza bikwiranye cyane niterambere ryiterambere ryingufu-nini, ntoya-LED.
