COB Packaging Zvinorevei? Ndeupi Musiyano Kubva Kuchinyakare Packaging

Chii chinonzi COB yakavharirwa Cache paBhodhi ) Bangbang yakaiswa pabhodhi rakadhindwa. Sezvo vatengesi veIC vari kuderedza QFP (nzira yekuisa encapsulation yezvikamu zveSMT) kurongedza muLCD kutonga uye kugadzirwa kwemachipi ane hukama. Naizvozvo, iyo yechinyakare SMT nzira mune ramangwana zvigadzirwa inotsiviwa zvishoma nezvishoma. Musiyano uripo pakati peCOB yekurongedza tekinoroji uye yechinyakare kurongedza? COB kurongedza ndiyo package inosunga iyo LED chip zvakananga paPCB board. Ndeupi mutsauko uripo pakati peiyi nzira yekurongedza uye yechinyakare SMD LED uye mamwe maitiro ekurongedza, uye ndeipi iri nani? Kuenzaniswa kweiyi nzira mbiri dzekurongedza? Kune miviri mikuru mikuru ye nude chip tekinoroji: imwe ndeye COB tekinoroji, uye imwe yacho FLIP Chip tekinoroji (FLIP Chip). LED COB yekurongedza tekinoroji Iyo inonzi COB ndeyekunamatira mushwi chip ine conductive kana isina-conductive adhesion pane yakabatana substrate, uyezve kuita kiyi inotungamira kuti iwane kubatanidza kwayo magetsi. Kana iyo yakashama chip yakananga zvakananga kumhepo, inogona kukanganisa kusvibiswa kana kukanganisa kwekugadzira, kukanganisa kana kuparadza basa re chip, saka chip uye key lead zvakavharwa neglue. Vanhu vanodaidzawo fomu iyi yekurongedza sebhegi rakapfava. Iyo nude chip yakavharidzirwa neCOB tekinoroji ndiyo chip main body uye I/O terminals pamusoro pekristaro. Munguva yewelding, nude chip inonamira kuPCB ine conductive/thermal glue. Mushure mekusimba ) Pasi pekuita kwe ultrasound uye kupisa kwemhepo, batanidza kune chip's I / O terminal welding nzvimbo uye mapadhi anoenderana nePCB, zvichiteerana. Mushure mokunge muedzo wapfuura, glue resin rinovharwa. Kuenzaniswa neyechinyakare yekurongedza tekinoroji, COB tekinoroji ine zvinotevera zvakanakira: mutengo wakaderera; kuchengetedza nzvimbo; hunyanzvi hwekuita. LED COB yekurongedza tekinoroji zvakare haina kukwana, ndiko kuti, yakaparadzana welding muchina uye mushini wekurongedza unodiwa. Dzimwe nguva kumhanya hakugone kuenderana nePCB chigamba chinoomesera zvinodiwa zvezvakatipoteredza; haigoni kuchengetedzwa. COB, iyi yechinyakare yekurongedza tekinoroji ichaita basa rakakosha mukurongedza kwezvinhu zvinotakurika. Matambudziko akajairika e LED COB yekurongedza tekinoroji Q: LED mwenje sosi COB yekurongedza maitiro Mid -color tembiricha yekumisa dambudziko. Kana COB kurongedza kuchishandiswa muCOB kurongedza, inoshandisa yechinyakare yakakwirira-simba kurongedza maitiro. Mushure mekubika, inowanikwa kuti kutonhora kwemavara kunogara kwakakura. , 5000K munzvimbo yekutanga, asi glue poda i10000K mushure mekunge grill yabikwa. Iro dambudziko rekubika kwesilicone kana glue powder haina kukodzera. Ndapota mose! A: Tembiricha yekubikira yakanyanya, uye chinhambwe che electrode chinova padyo. Pfupisa nguva yepfapfaidzo kusvika panguva yekubikira. Kusiyana kwekushisa kwemavara kunofanira kukonzerwa nehupfu hwefluorescent. Kurumidza kuomesa kudzivirira fluorescence poda! Ongorora iyo yekudziya curve yeOven bhokisi Q: Ndeupi musiyano uripo pakati peLAMP LED yekurongedza tekinoroji uye COB kurongedza mune yekurongedza tekinoroji yeLED? Ose ari maviri akananga-akaiswa pachinzvimbo chekuisa chigamba. Chii chakasiyana? Ndezvipi zvinhu? Imwe inokodzera simba repamusoro, imwe yesimba diki? A: Tekinoroji yeCOB inowanzo shanda kune imwechete substrate nezvimwe zvinhu zvemagetsi. Kana iyo LED COB ikaitwa yakananga encapsulation package, inofanirwa kunge iri module ine mamwe mabasa akakosha senge flash function kana dijitari hunhu, color control module, nezvimwe. Ese masimba makuru uye madiki anogona kuve COB kana LAMP. Hapana mutsauko pachinhu ichi. Mubvunzo: Ndingabvunza COB yakasanganiswa kurongedza senge mwenje mwenje sosi, ichatsiva yazvino chigamba zvigadzirwa? A: Hapana chinotsiva, ese ari mukusimudzira mune ramangwana, uye ese ari maviri achagara kwenguva yakareba.
