Mune tekinoroji yemazuva ano yekuratidzira tekinoroji, kuratidzwa kwe LED kunoshandiswa zvakanyanya mumasaini edhijitari, kumashure kwechikuva, kushongedza kwemukati uye mamwe minda nekuda kwekupenya kwayo kwakanyanya, tsananguro yepamusoro, hupenyu hurefu uye zvimwe zvakanaka. Mukugadzira maitiro ekuratidzwa kwe LED, encapsulation tekinoroji ndiyo yakakosha link. Pakati pavo, SMD encapsulation tekinoroji uye COB encapsulation tekinoroji maviri makuru encapsulation. Saka, ndeupi musiyano pakati pavo? Ichi chinyorwa chichakupa iwe nekuongorora kwakadzama.
1.what is SMD packaging technology, SMD packaging musimboti
SMD package, zita rakazara Surface Mounted Device (Surface Mounted Device), imhando yezvigadzirwa zvemagetsi zvakasungirirwa zvakananga kune yakadhindwa yedunhu bhodhi (PCB) pamusoro pekurongedza tekinoroji. Iyi tekinoroji kuburikidza nechaiyo yekuisa muchina, iyo encapsulated LED chip (kazhinji ine LED mwenje-emitting diodes uye inodiwa yedunhu zvikamu) yakanyatsoiswa paPCB pads, uyezve kuburikidza reflow soldering uye dzimwe nzira dzekuziva kubatanidzwa kwemagetsi.SMD kurongedza. tekinoroji inoita kuti zvinhu zvemagetsi zvive zvidiki, zvireruke muhuremu, uye zvienderane nekugadzirwa kweakawanda compact uye lightweight zvigadzirwa zvemagetsi.
2.Zvakanakira uye Zvakaipa zveSMD Packaging Technology
2.1 SMD Packaging Technology Advantages
(1)saizi diki, huremu huremu:SMD kurongedza zvikamu zvidiki muhukuru, zviri nyore kubatanidza yakakwirira-density, inoenderana nekugadzirwa kweminiaturized uye lightweight zvigadzirwa zvemagetsi.
(2)yakanaka high-frequency maitiro:mapini mapfupi uye nzira pfupi dzekubatanidza dzinobatsira kuderedza inductance uye kuramba, kunatsiridza kuita kwepamusoro-frequency performance.
(3)Yakanakira kugadzira otomatiki:inokodzera otomatiki yekuisa muchina kugadzirwa, kunatsiridza kugadzirwa kwakanaka uye kugadzikana kwemhando.
(4)Kuita kwakanaka kwekushisa:kutarisana kwakananga nePCB pamusoro, kunobatsira pakupisa kupisa.
2.2 SMD Packaging Technology Zvakaipa
(1)kugadzirisa kwakaoma: kunyange zvazvo nzira yekusimudza pamusoro inoita kuti zvive nyore kugadzirisa uye kutsiva zvikamu, asi munyaya yekubatanidzwa kwepamusoro-density, kuchinjwa kwezvikamu zvega zvinogona kunge zvakanyanya kuoma.
(2)Nzvimbo shoma yekubvisa kupisa:kunyanya kuburikidza nepedhi uye gel kupisa kupisa, nguva yakareba basa rekutakura rinogona kutungamira mukupisa kwekupisa, kukanganisa hupenyu hwebasa.
3.chii chinonzi COB kurongedza tekinoroji, COB yekurongedza musimboti
COB package, inozivikanwa seChip paBhodhi (Chip paBhodhi package), iri chip chip chakanyatso simbirwa paPCB yekurongedza tekinoroji. Iyo chaiyo maitiro ndeye isina chip (chip body uye I / O zviteshi mukristaro kumusoro) ine conductive kana inopisa inonamira yakasungirirwa kuPCB, uyezve kuburikidza newaya (yakadai sealuminium kana goridhe waya) mune ultrasonic, pasi pechiito. yekupisa kupisa, iyo chip's I / O zviteshi uye maPCB pads akabatana kumusoro, uye pakupedzisira akaiswa chisimbiso neresin adhesive dziviriro. Iyi encapsulation inobvisa echinyakare LED mwenje bead encapsulation matanho, zvichiita kuti pasuru yacho ive compact.
4.Zvakanakira uye zvakaipira zveCOB yekurongedza tekinoroji
4.1 COB yekurongedza tekinoroji zvakanakira
(1) compact package, saizi diki:kubvisa mapini epasi, kuwana saizi diki yepasuru.
(2) kuita kwepamusoro:waya yegoridhe inobatanidza chip uye bhodhi redunhu, iyo chiratidzo chekufambisa chinhambwe ipfupi, ichideredza crosstalk uye inductance uye dzimwe nyaya dzekuvandudza mashandiro.
(3) Kupisa kwakanaka kwekupisa:iyo chip inobatanidzwa zvakananga kuPCB, uye kupisa kunobviswa kuburikidza nePCB board yose, uye kupisa kunopera nyore nyore.
(4) Kuita kwakasimba kwekudzivirira:dhizaini yakavharirwa zvizere, ine kusapinda kwemvura, hunyoro-uchapupu, guruva-uchapupu, anti-static uye mamwe mabasa ekudzivirira.
(5) chiitiko chakanaka chekuona:senzvimbo yemwenje sosi, kuita kwemavara kunowedzera kujeka, kwakanyanya kunaka kugadzirisa, kwakakodzera kwenguva yakareba yekutarisa.
4.2 COB yekurongedza tekinoroji zvakashata
(1) matambudziko ekugadzirisa:chip uye PCB yakananga welding, haigone kuparadzaniswa zvakasiyana kana kutsiva chip, mari yekugadzirisa yakakwira.
(2) yakasimba kugadzirwa zvinodiwa:iyo yekurongedza yezvinodiwa zvezvakatipoteredza yakakwira zvakanyanya, haitenderi guruva, static magetsi uye zvimwe zvinosvibisa zvinhu.
5. Musiyano pakati peSMD packaging tekinoroji uye COB yekurongedza tekinoroji
SMD encapsulation tekinoroji uye COB encapsulation tekinoroji mumunda we LED kuratidza imwe neimwe ine yayo yakasarudzika maficha, mutsauko pakati pavo unonyanya kuratidzwa mu encapsulation, saizi uye uremu, kupisa kupisa kuita, nyore kuchengetedza uye mamiriro ekushandisa. Izvi zvinotevera kuenzanisa kwakadzama uye ongororo:
5.1 Packaging nzira
⑴SMD yekurongedza tekinoroji: zita rakazara iSurface Mounted Device, inova tekinoroji yekurongedza inotengesa iyo yakavharwa LED chip pamusoro peiyo yakadhindwa yedunhu bhodhi (PCB) kuburikidza nechaiyo chigamba muchina. Iyi nzira inoda kuti chipu che LED chivharwe pachine nguva kuti chigadzire chikamu chakazvimiririra chobva chaiswa paPCB.
⑵COB yekurongedza tekinoroji: zita rakazara ndiChip paBhodhi, inova tekinoroji yekurongedza inotengesa zvakananga chip isina chinhu paPCB. Iyo inobvisa nhanho dzekurongedza dzechinyakare mwenje mabhero e LED, inosunga yakananga chip kuPCB ine conductive kana thermal conductive glue, uye inoziva kubatana kwemagetsi kuburikidza nesimbi waya.
5.2 Saizi uye uremu
⑴SMD kurongedza: Kunyangwe izvo zvikamu zvidiki muhukuru, saizi yavo uye huremu zvichiri kushoma nekuda kwepakurongedza chimiro uye padhi zvinodiwa.
⑵COB package: Nekuda kwekusiiwa kwepini dzepasi uye ganda repakeji, COB package inowana yakanyanyisa compactness, ichiita kuti pasuru yacho ive diki uye kureruka.
5.3 Kupisa kupisa kwekuita
⑴SMD kurongedza: Kunyanya kuburitsa kupisa kuburikidza nemapadhi uye colloids, uye nzvimbo yekupisa yekupisa ishoma. Pasi pekupenya kwepamusoro uye mamiriro ekutakura, kupisa kunogona kuiswa munzvimbo ye chip, zvichikanganisa hupenyu nekugadzikana kwekuratidzira.
⑵COB package: Iyo chip inosungirirwa zvakananga paPCB uye kupisa kunogona kubviswa kuburikidza nePCB board yese. Iyi dhizaini inovandudza zvakanyanya kupisa kwekupisa kwechiratidziro uye inoderedza kukundikana kwehuwandu nekuda kwekupisa.
5.4 Kunaka kwekuchengetedza
⑴SMD kurongedza: Sezvo zvikamu zvakaiswa zvakazvimirira paPCB, zviri nyore kutsiva chikamu chimwe panguva yekugadzirisa. Izvi zvinobatsira kuderedza mari yekugadzirisa uye kupfupisa nguva yekugadzirisa.
⑵COB kurongedza: Sezvo chip nePCB zvakabatanidzwa zvakananga kuita yakazara, hazvigoneke kuparadzanisa kana kutsiva chip zvakasiyana. Kamwe kukanganisa kunoitika, zvinowanzodiwa kutsiva iyo PCB board yese kana kuidzosera kufekitori kuti igadziriswe, izvo zvinowedzera mutengo uye kuoma kwekugadzirisa.
5.5 Mamiriro ekushandisa
⑴SMD kurongedza: Nekuda kwekukura kwayo uye mutengo wakaderera wekugadzira, inoshandiswa zvakanyanya mumusika, kunyanya mumapurojekiti asingadhuri uye anoda kugadziridzwa kwakanyanya, senge mabhodhi ekunze uye mukati meTV madziro.
⑵COB kurongedza: Nekuda kwekuita kwayo kwepamusoro uye kuchengetedzwa kwepamusoro, inonyanya kukodzera kune yakakwirira-yekupedzisira mukati memukati kuratidza masikirini, veruzhinji, makamuri ekutarisa uye zvimwe zviratidziro zvine yakakwirira yemhando zvinodiwa uye nharaunda dzakaoma. Semuenzaniso, munzvimbo dzekuraira, masitudiyo, nzvimbo huru dzekutumira uye dzimwe nharaunda uko vashandi vanotarisa skrini kwenguva yakareba, COB yekurongedza tekinoroji inogona kupa yakapfava uye yakafanana yekuona ruzivo.
Mhedziso
SMD yekurongedza tekinoroji uye COB yekurongedza tekinoroji imwe neimwe ine yayo yakasarudzika mabhenefiti uye mamiriro ekushandisa mumunda we LED kuratidza skrini. Vashandisi vanofanira kuyera uye kusarudza zvinoenderana nezvinodiwa chaizvo pakusarudza.
SMD yekurongedza tekinoroji uye COB yekurongedza tekinoroji vane yavo yakanakira. SMD yekurongedza tekinoroji inoshandiswa zvakanyanya mumusika nekuda kwekukura kwayo uye mutengo wakaderera wekugadzira, kunyanya mumapurojekiti anodhura uye anoda kurerukirwa kwekugadzirisa. COB packaging tekinoroji, kune rumwe rutivi, ine kukwikwidza kwakasimba mu-yepamusoro-yekupedzisira mukati mekuratidzira skrini, zviratidziro zveveruzhinji, makamuri ekutarisa uye mimwe minda ine compact packaging, kuita kwepamusoro, kupisa kwakanaka kwekupisa uye kushanda kwakasimba kwekudzivirira.
