Kunyatsojeka kwezvakadzikaUV LEDinonyanya kurongedzerwa nekunze kwehuwandu hwehuwandu, iyo inobatwa nemukati quantum kunyatsoshanda uye chiedza chekubvisa chiedza. Nekuvandudzwa kunoramba kuchienderera mberi (> 80%) yehuwandu hwemukati hwehuwandu hwehurefu hweUV LED, chiedza chekubudisa chiedza cheyakadzika UV LED chave chinhu chinokosha chinomisa kuvandudzwa kwechiedza cheyakadzika UV LED, uye chiedza chekubudisa chiedza che. yakadzika UV LED inobatwa zvakanyanya neiyo yekurongedza tekinoroji. Iyo yakadzika UV LED yekurongedza tekinoroji yakasiyana neyezvino chena LED yekurongedza tekinoroji. White LED inonyanya kuputirwa ne organic zvinhu (epoxy resin, silica gel, nezvimwewo), asi nekuda kwehurefu hweyakadzika UV mwenje wave uye yakakwira simba, organic zvinhu zvinozosangana nekusvibiswa kweUV pasi penguva yakareba yakadzika UV mwaranzi, iyo inokanganisa zvakanyanya. iko kushanda kwechiedza uye kuvimbika kweyakadzika UV LED. Naizvozvo, yakadzika UV LED kurongedza kunonyanya kukosha pakusarudzwa kwezvinhu.

LED packaging zvinhu zvinonyanya zvinosanganisira mwenje emitting materials, heat dissipation substrate zvinhu uye welding bonding zvinhu. Iyo mwenje emitting material inoshandiswa chip luminescence extraction, light regulation, mechanical protection, etc; Heat dissipation substrate inoshandiswa kune chip magetsi ekubatanidza, kupisa kupisa uye kutsigirwa kwemagetsi; Welding bonding zvinhu zvinoshandiswa chip solidification, lens bonding, nezvimwe.

1. chiedza chinobudisa zvinhu:theChiedza che LEDemitting chimiro chinowanzo tora zvinhu zvakajeka kuti uone kubuda kwechiedza uye kugadzirisa, uku uchidzivirira chip uye redunhu layer. Nekuda kwekushomeka kwekupisa kwekupisa uye kuderera kwekupisa kwemafuta ezve organic zvinhu, kupisa kunogadzirwa neyakadzama UV LED chip kuchaita kuti tembiricha yeorganic packaging layer ikwire, uye organic zvinhu zvinozoora nekupisa, kuchembera kwemafuta uye kunyange isingadzokeri carbonization. pasi pekushisa kwepamusoro kwenguva yakareba; Uye zvakare, pasi peyakanyanya-simba ultraviolet nemwaranzi, iyo organic yekurongedza layer ichava neshanduko dzisingadzoreki dzakadai sekudzikira transmittance uye microcracks. Nekuenderera mberi kwekuwedzera kwesimba rakadzika reUV, matambudziko aya anowedzera kuoma, zvichiita kuti zviome kune zvechinyakare organic zvinhu kusangana nezvinodiwa zvakadzika UV LED kurongedza. Kazhinji, kunyangwe zvimwe organic zvinhu zvakanzi zvinokwanisa kumira ultraviolet mwenje, nekuda kwekushomeka kwekushisa kupisa uye kusapindirana kwemhepo kwezvinhu zve organic, organic zvinhu zvichiri kushoma muyakadzika UV.LED kurongedza. Naizvozvo, vaongorori vari kugara vachiedza kushandisa inorganic transparent materials senge quartz girazi nesafire kurongedza yakadzika UV LED.

2. kupisa kupisa substrate zvinhu:parizvino, LED kupisa dissipation substrate zvinhu zvinonyanya kusanganisira resin, simbi uye ceramic. Zvose resin uye simbi substrates dzine organic resin insulation layer, iyo inoderedza kupisa kwekushisa kweiyo inopisa kupisa substrate uye inokanganisa kupisa kwekushisa kwe substrate; Ceramic substrates inonyanya kusanganisira yakakwirira / yakaderera tembiricha co fired ceramic substrates (HTCC /ltcc), gobvu firimu ceramic substrates (TPC), copper-clad ceramic substrates (DBC) uye electroplated ceramic substrates (DPC). Ceramic substrates ine akawanda mabhenefiti, akadai seyakakwira mechanical simba, yakanaka insulation, high thermal conductivity, yakanaka kupisa kupisa, yakaderera coefficient yekuwedzera kupisa uye zvichingodaro. Iwo anoshandiswa zvakanyanya mumagetsi mudziyo kurongedza, kunyanya yakakwirira-simba LED kurongedza. Nekuda kwekushomeka kwechiedza cheyakadzika UV LED, mazhinji emagetsi ekuisa simba anoshandurwa kuita kupisa. Kuti udzivise kukanganisa kwepamusoro-soro kune chip chinokonzerwa nekupisa kwakanyanya, kupisa kunogadzirwa nechipsi kunoda kuparara munzvimbo yakapoteredza munguva. Nekudaro, iyo yakadzika UV LED inonyanya kutsamira pane inopisa dissipation substrate seyo kupisa conduction nzira. Naizvozvo, iyo yakakwira yekupisa conductivity ceramic substrate isarudzo yakanaka yekupisa kupisa substrate yekudzika UV LED kurongedza.

3. welding bonding zvinhu:yakadzika UV LED welding zvinhu zvinosanganisira chip solid crystal zvinhu uye substrate welding zvinhu, izvo zvinoshandiswa zvakatevedzana kuona welding pakati pechip, girazi chivharo (lens) uye ceramic substrate. Kune flip chip, Goridhe Tin eutectic nzira inowanzo shandiswa kuona chip kusimba. Kune akachinjika uye akatwasuka machipisi, conductive sirivheri glue uye lead-isina solder paste inogona kushandiswa kupedzisa chip solidification. Kuenzaniswa nesirivheri glue uye lead-isina solder paste, iyo Goridhe Tin eutectic bonding simba yakakwira, iyo interface yemhando yakanaka, uye iyo yekupisa conductivity yebonding layer yakakwira, iyo inoderedza iyo LED kupisa kuramba. Girazi rekuvhara ndiro rakaiswa welded mushure meiyo chip solidification, saka tembiricha yewelding inoganhurwa nekupisa kwekupokana kweiyo chip solidification layer, kunyanya kusanganisira yakananga kubatanidza uye solder bonding. Kusungirirana kwakananga hakudi zvepakati pekubatanidza zvinhu. Iyo yakanyanya tembiricha uye yakanyanya kudzvanywa nzira inoshandiswa kupedzisa zvakananga kubatira pakati pegirazi rekuvhara ndiro uye ceramic substrate. Iyo yekubatanidza interface yakadzika uye ine simba rakawanda, asi ine zvakakwirira zvinodiwa zvemidziyo uye kudzora maitiro; Solder bonding inoshandisa yakaderera-tembiricha tin based solder seyepakati layer. Pasi pemamiriro ekudziya uye kumanikidzwa, kusungirirwa kunopedzwa nekubatanidzwa kweatomu pakati pe solder layer nesimbi. Iyo tembiricha yemaitiro yakaderera uye kushanda kuri nyore. Parizvino, solder bonding inowanzoshandiswa kuona hukama hwakavimbika pakati pegirazi rekuvhara ndiro uye ceramic substrate. Zvisinei, simbi dzakaturikidzana dzinoda kugadzirirwa pamusoro pegirazi chivharo ndiro uye zvedongo substrate panguva imwe chete kusangana zvinodiwa simbi nomoto, uye solder kusarudzwa, solder unhani, solder kufashukira uye welding tembiricha zvinofanira kufungwa mu bonding muitiro. .

Mumakore achangopfuura, vaongorori vekumba nekune dzimwe nyika vakaita tsvakiridzo yakadzama pamusoro pezvakadzika UV LED yekurongedza zvinhu, izvo zvakavandudza kupenya kwakanaka uye kuvimbika kweyakadzika UV LED kubva pakuona kwekurongedza zvinhu tekinoroji, uye nekusimudzira zvinobudirira kuvandudzwa kwakadzika UV. LED tekinoroji.
