Kumurika kwimbitseUV LEDbigenwa cyane cyane nubushobozi bwo hanze bwa kwant, bugira ingaruka kumikorere yimbere no gukora neza.Hamwe nogukomeza gutera imbere (> 80%) byimikorere yimbere ya UV LED yimbitse, uburyo bwo gukuramo urumuri rwa UV LED bwimbitse byabaye ikintu cyingenzi kigabanya iterambere ryumucyo wa UV LED yimbitse, hamwe nuburyo bwo gukuramo urumuri byimbitse UV LED yibasiwe cyane nubuhanga bwo gupakira.Ubuhanga bwimbitse bwa UV LED buratandukanye nubuhanga bugezweho bwa LED bwo gupakira.LED yera yuzuyemo ibikoresho kama (epoxy resin, silika gel, nibindi), ariko kubera uburebure bwumurabyo mwinshi wa UV ningufu nyinshi, ibikoresho kama bizangirika UV munsi yumuriro muremure wa UV, bigira ingaruka zikomeye. urumuri rukora neza kandi rwizewe rwimbitse UV LED.Kubwibyo, gupakira cyane UV LED ni ngombwa cyane muguhitamo ibikoresho.

Ibikoresho byo gupakira LED birimo ibikoresho bisohora urumuri, ibikoresho byo gukwirakwiza ubushyuhe hamwe nibikoresho byo gusudira.Ibikoresho bisohora urumuri bikoreshwa mugukuramo chip luminescence, kugenzura urumuri, kurinda imashini, nibindi;Ubushyuhe bwo gukwirakwiza ubushyuhe bukoreshwa muguhuza amashanyarazi amashanyarazi, gukwirakwiza ubushyuhe no gushyigikira imashini;Ibikoresho byo gusudira bikoreshwa mugukomera chip, guhuza lens, nibindi.

1. ibikoresho bisohora urumuri:iItaragusohora imiterere muri rusange ifata ibikoresho bibonerana kugirango ibone urumuri rusohoka kandi ruhindurwe, mugihe urinda chip nu ruziga.Bitewe nubushyuhe buke hamwe nubushyuhe buke bwibikoresho kama, ubushyuhe butangwa na chip ndende ya UV LED bizatera ubushyuhe bwurwego rwo gupakira kama, kandi ibikoresho kama bizangirika kwangirika kwubushyuhe, gusaza kwubushyuhe ndetse na karubone idasubirwaho. munsi yubushyuhe bwo hejuru igihe kirekire;Byongeye kandi, munsi yumuriro mwinshi ultraviolet imirasire, igipfunyika kama kama kizagira impinduka zidasubirwaho nko kugabanuka kwinshi na microcrack.Hamwe nogukomeza kwiyongera kwingufu za UV zimbitse, ibyo bibazo birakomera, bigatuma bigora ibikoresho kama gakondo guhuza ibikenewe byapakirwa UV LED.Muri rusange, nubwo hari ibikoresho kama byavuzwe ko bishobora kwihanganira urumuri rwa ultraviolet, kubera ubushyuhe buke ndetse nubushyuhe buke bwibikoresho kama, ibikoresho kama biracyari bike muri UV yimbitseGupakira LED.Kubwibyo, abashakashatsi bahora bagerageza gukoresha ibikoresho bitagaragara munganda nkibirahuri bya quartz na safiro kugirango bapakire UV LED.

2. ibikoresho byo gukwirakwiza ubushyuhe ibikoresho:kuri ubu, ibikoresho bya LED byo gukwirakwiza ibikoresho birimo resin, ibyuma na ceramic.Byombi bya resin hamwe nicyuma kirimo insina ngengabihe, bizagabanya ubushyuhe bwumuriro wa substrate yo gukwirakwiza ubushyuhe kandi bikagira ingaruka kumikorere yubushyuhe bwa substrate;Ububiko bwa Ceramic burimo cyane cyane ubushyuhe buke / buke co co kurasa ceramic substrate (HTCC / ltcc), firime yubutaka bwa ceramic substrate (TPC), ceramic substrate substrate (DBC) hamwe nubutaka bwa ceramic (DPC).Ceramic substrates ifite ibyiza byinshi, nkimbaraga zo gukanika cyane, izirinda neza, itwara ubushyuhe bwinshi, irwanya ubushyuhe bwiza, coefficient nkeya yo kwagura ubushyuhe nibindi.Zikoreshwa cyane mubikoresho bipfunyika, cyane cyane bipfunyika LED.Bitewe numucyo muke wa UV LED yimbitse, ingufu nyinshi zinjiza amashanyarazi zihinduka ubushyuhe.Kugirango wirinde kwangirika kwubushyuhe bukabije kuri chip iterwa nubushyuhe bukabije, ubushyuhe butangwa na chip bugomba gukwirakwizwa mubidukikije mugihe gikwiye.Nyamara, ubujyakuzimu bwa UV LED bushingiye cyane cyane ku gukwirakwiza ubushyuhe nk'inzira yo gutwara ubushyuhe.Kubwibyo, ubushyuhe bwo hejuru bwa ceramic substrate nuburyo bwiza bwo guhitamo ubushyuhe bwo gukwirakwiza ubushyuhe bwa UV LED ipakira.

3. gusudira ibikoresho byo guhuza:ibikoresho byimbitse bya UV LED birimo ibikoresho bikomeye bya kristu hamwe nibikoresho byo gusudira bya substrate, bikoreshwa mukumenya gusudira hagati ya chip, igifuniko cy'ikirahure (lens) na ceramic substrate.Kuri flip chip, Uburyo bwa Gold Tin eutectic bukoreshwa kenshi kugirango tumenye gukomera.Kuri horizontal itambitse kandi ihagaritse, ifeza ya feza ikora hamwe na paste idafite kugurisha paste irashobora gukoreshwa kugirango irangize chip.Ugereranije na kole ya feza hamwe na paste idafite ibicuruzwa bigurishwa, Gold Tin eutectic ihuza imbaraga ni ndende, ubwiza bwimbere ni bwiza, kandi nubushyuhe bwumuriro bwurwego ruhuza ni muremure, bigabanya ubushyuhe bwa LED.Isahani yo gupfundikira ikirahuri irasudwa nyuma yo gukomera kwa chip, bityo ubushyuhe bwo gusudira bugarukira kubushyuhe bwo guhangana na chip ikomeye, cyane cyane guhuza no kugurisha.Guhuza bitaziguye ntibisaba ibikoresho byo hagati.Ubushyuhe bwo hejuru hamwe nuburyo bwumuvuduko mwinshi bikoreshwa mukurangiza mu buryo butaziguye gusudira hagati yisahani yikirahure hamwe na ceramic substrate.Imigaragarire ihuza iringaniye kandi ifite imbaraga nyinshi, ariko ifite ibisabwa byinshi kubikoresho no kugenzura inzira;Guhuza ibicuruzwa bikoresha ubushyuhe buke bwamabati ashingiye kugurisha nkurwego rwagati.Mugihe cyo gushyushya nigitutu, guhuza byuzuzwa no gukwirakwiza atome hagati yuwagurishije nicyuma.Ubushyuhe bwibikorwa buri hasi kandi imikorere iroroshye.Kugeza ubu, kugurisha kugurisha akenshi bikoreshwa kugirango tumenye isano iri hagati yisahani yikirahure na ceramic substrate.Nyamara, ibyuma bigomba gutegurwa hejuru yicyapa gipfundikira ibirahuri hamwe nubutaka bwa ceramic icyarimwe kugirango byuzuze ibisabwa byo gusudira ibyuma, no guhitamo abagurisha, gutwikira ibicuruzwa, kugurisha ibicuruzwa hamwe nubushyuhe bwo gusudira bigomba kwitabwaho mugikorwa cyo guhuza .

Mu myaka yashize, abashakashatsi mu gihugu ndetse no hanze yacyo bakoze ubushakashatsi bwimbitse ku bikoresho byapakiye UV LED, byateje imbere urumuri n’ubwizerwe bwa UV LED yimbitse hifashishijwe ibikoresho byo gupakira, kandi biteza imbere iterambere rya UV yimbitse. Ikoranabuhanga rya LED.
