1. Nhanganyaya kuSMD Packaging Technology
1.1 Tsanangudzo uye Kumashure kweSMD
SMD yekurongedza tekinoroji imhando yemagetsi chikamu chekurongedza. SMD, iyo inomiririra Surface Mounted Device, inyanzvi inoshandiswa zvakanyanya muindasitiri yekugadzira zvemagetsi yekurongedza akasanganiswa edunhu machipisi kana zvimwe zvinhu zvemagetsi kuti zvigadzirwe zvakananga pamusoro pePCB (Yakadhindwa Circuit Board).
1.2 Hunhu Huru
Diki Size:SMD dzakaputirwa zvikamu zvakakochekerana, zvichigonesa kubatanidzwa kwepamusoro-density, iyo inobatsira pakugadzira miniaturized uye yakareruka zvigadzirwa zvemagetsi.
Kurema kwakareruka:Zvikamu zveSMD hazvidi zvinotungamira, zvichiita kuti chimiro chese chireruke uye chinokodzera zvikumbiro zvinoda kuderedzwa uremu.
Yakanakisa High-Frequency Characteristics:Iwo mapfupi anotungamira uye akabatana muzvikamu zveSMD anobatsira kuderedza inductance uye kuramba, kusimudzira yakakwira-frequency performance.
Inokodzera Kugadzirwa Kwemagetsi:Zvikamu zveSMD zvakakodzerwa neotomatiki yekuisa michina, kuwedzera hunyanzvi hwekugadzira uye kugadzikana kwemhando.
Yakanaka Thermal Performance:Zvikamu zveSMD zvinosangana zvakananga nePCB pamusoro, iyo inobatsira mukupisa kupisa uye inovandudza mashandiro ekupisa.
Zviri Nyore Kugadzirisa uye Kuchengeta:Iyo yepamusoro-yepamusoro nzira yeSMD zvikamu zvinoita kuti zvive nyore kugadzirisa uye kutsiva zvikamu.
Packaging Types:SMD kurongedza inosanganisira akasiyana marudzi akadai seSOIC, QFN, BGA, uye LGA, imwe neimwe iine mabhenefiti chaiwo uye anoshanda mamiriro.
Kuvandudza Tekinoroji:Kubva payakaunzwa, SMD yekurongedza tekinoroji yave imwe yeakanyanya kurongedza matekinoroji muindasitiri yekugadzira zvemagetsi. Nekufambira mberi kwetekinoroji uye kudiwa kwemusika, tekinoroji yeSMD inoramba ichishanduka kuti isangane nezvinodiwa zvekushanda kwepamusoro, hukuru hudiki, uye mutengo wakaderera.
2. Kuongororwa kweCOB Packaging Technology
2.1 Tsanangudzo uye Mabviro eCOB
COB yekurongedza tekinoroji, inomiririra Chip paBhodhi, inzira yekurongedza umo machipisi akaiswa zvakananga paPCB (Printed Circuit Board). Iyi tekinoroji inonyanya kushandiswa kugadzirisa nyaya dzekupisa kupisa kwe LED uye kuzadzisa kubatanidzwa kwakasimba pakati peiyo chip nebhodhi redunhu.
2.2 Technical Principle
COB kurongedza kunosanganisira kubatanidza isina machipisi kune inobatana substrate uchishandisa conductive kana isina-conductive adhesives, inoteverwa newaya bonding kumisikidza magetsi. Munguva yekurongedza, kana iyo isina chip yakafumurwa kumhepo, inogona kusvibiswa kana kukuvadzwa. Naizvozvo, zvinonamira zvinowanzoshandiswa kuvharidzira chip uye waya dzekubatanidza, kugadzira "soft encapsulation."
2.3 Unyanzvi Zvimiro
Compact Packaging: Nekubatanidza kurongedza nePCB, saizi yechip inogona kuderedzwa zvakanyanya, nhanho yekubatanidza yakawedzera, dhizaini dhizaini yakagadziridzwa, kuoma kwedunhu kuderedzwa, uye kugadzikana kwehurongwa kunovandudzwa.
Kugadzikana Kwakanaka: Yakananga chip soldering paPCB inoguma nekudedera kwakanaka uye kushomeka kuramba, kuchengetedza kugadzikana munzvimbo dzakaoma senge tembiricha yepamusoro uye hunyoro, nekudaro ichiwedzera hupenyu hwechigadzirwa.
Yakanakisa Thermal Conductivity: Kushandisa thermal conductive adhesives pakati pe chip nePCB zvinobudirira kuwedzera kupisa kupisa, kuderedza kupisa kunokanganisa pane chip uye kunatsiridza chip hupenyu.
Mutengo Wakaderera Wekugadzira: Pasina kudiwa kwevanotungamira, inobvisa mamwe maitiro akaomarara anosanganisira zvinobatanidza uye zvinotungamira, kuderedza mutengo wekugadzira. Pamusoro pezvo, inobvumira kugadzirwa otomatiki, kudzikisa mutengo wevashandi uye kuvandudza hunyanzvi hwekugadzira.
2.4 Chengetedzo
Zvakaoma Kugadzirisa: Kutengesa kwakananga kwechip kuPCB kunoita kuti munhu abvise chip kana kutsiva zvisaite, izvo zvinoda kutsiviwa kwePCB yese, kuwedzera mari uye kuomerwa kwekugadzirisa.
Kuvimbika Matambudziko: Machipisi akamisikidzwa mumanamira anogona kukuvadzwa panguva yekubvisa, zvichigona kukonzera kukuvadzwa kwepadhi uye kukanganisa kugadzirwa kwemhando.
Yakakwirira Yezvakatipoteredza Zvinodiwa: Iyo COB yekurongedza maitiro inoda guruva-isina, static-isina nharaunda; kana zvisina kudaro, chiyero chekukundikana chinowedzera.
3. Kuenzanisa kweSMD neCOB
Saka, ndeupi musiyano uripo pakati peaya matekinoroji maviri?
3.1 Kufananidza kweKuona Zvakaitika
COB inoratidzira, iine mwenje wepasi mwenje sosi maitiro, inopa vataridzi zvakanakisa uye zvakangofanana zviitiko zvekuona. Kuenzaniswa nenzvimbo yemwenje sosi yeSMD, COB inopa mamwe mavara akajeka uye zvirinani kubata, zvichiita kuti ive yakakodzera kwenguva refu, yepedyo-kumusoro kuona.
3.2 Kufananidza Kugadzikana uye Kuchengetedza
Nepo zviratidziro zveSMD zviri nyore kugadzirisa pa-saiti, zvine dziviriro isina kusimba uye inotapukirwa nemamiriro ekunze. Kusiyana neizvi, COB inoratidzira, nekuda kwedhizaini yavo yese yekurongedza, ine mazinga ekudzivirira epamusoro, nekuita kuri nani kusapinda kwemvura uye guruva. Nekudaro, zvinofanirwa kucherechedzwa kuti COB inoratidza kazhinji inoda kudzoserwa kufekitori kuti igadziriswe kana ikatadza.
3.3 Kushandisa Simba uye Kushanda Kwesimba
Iine inobstructed flip-chip process, COB ine yakakwira mwenje sosi kushanda zvakanaka, zvichikonzera kuderera kwesimba rekushandisa kwekupenya kwakafanana, kuchengetedza vashandisi pamitengo yemagetsi.
3.4 Mutengo uye Kubudirira
SMD yekurongedza tekinoroji inoshandiswa zvakanyanya nekuda kwekukura kwayo kwakanyanya uye mutengo wakaderera wekugadzira. Kunyangwe tekinoroji yeCOB ichiti ine mutengo wakaderera, maitiro ayo akaomarara ekugadzira uye yakaderera goho parizvino inokonzeresa kudhura chaiko. Nekudaro, sezvo tekinoroji ichifambira mberi uye huwandu hwekugadzira hunowedzera, mutengo weCOB unotarisirwa kuramba uchidzikira.
4. Future Development Trends
RTLED piyona muCOB LED kuratidza tekinoroji. YeduCOB LED inoratidzaanoshandiswa zvakanyanya mumarudzi ese ekutengeserana LED anoratidzanekuda kwemaitiro avo akanaka ekuratidzira uye kuita kwakavimbika. RTLED yakazvipira kupa emhando yepamusoro, imwe-yekumira kuratidza mhinduro kuti isangane nevatengi vedu zvinodiwa zvepamusoro-tsanangudzo yekuratidzira uye kuchengetedza simba uye kuchengetedza kwezvakatipoteredza. Isu tinoenderera mberi nekugadzirisa tekinoroji yedu yeCOB yekurongedza kuunza vatengi vedu zvigadzirwa zvemakwikwi nekuvandudza mwenje sosi kushanda zvakanaka uye kuderedza mutengo wekugadzira. Yedu COB LED skrini haina kungoita yakanakisa yekuona maitiro uye kugadzikana kwepamusoro, asi zvakare inogona kushanda yakatsiga munzvimbo dzakasiyana dzakaoma, ichipa vashandisi ruzivo runogara kwenguva refu.
Mumusika wekutengesa we LED, zvese COB neSMD zvine zvazvakanakira. Nekuwedzera kuri kuita kudiwa kwepamusoro-tsanangudzo yekuratidzira, Micro LED kuratidza zvigadzirwa zvine yakakwira pixel density zviri kuwana zvishoma nezvishoma kufarirwa kwemusika. COB tekinoroji, ine yakanyatsobatanidzwa yekurongedza maitiro, yave yakakosha tekinoroji yekuwana yakakwira pixel density muMicro LEDs. Panguva imwecheteyo, sezvo pixel pitch ye LED skrini ichiramba ichidzikira, mukana wemutengo weCOB tekinoroji uri kuwedzera kuoneka.
5. Pfupiso
Nekuenderera mberi kwetekinoroji uye kukura kwemusika, COB uye SMD yekurongedza matekinoroji icharamba ichiita mabasa akakosha muindasitiri yekuratidzira yekushambadzira. Tine chikonzero chekutenda kuti munguva pfupi iri kutevera, matekinoroji maviri aya anozosimudzira indasitiri kune tsananguro yepamusoro, hungwaru, uye hushamwari hwenzvimbo.
Kana iwe uchifarira ma LED anoratidza,taura nesu nhasikune mamwe ma LED skrini mhinduro.
