Sezvo zviratidziro zve LED zviri kunyanya kushandiswa zvakanyanya, vanhu vane zvinodiwa zvepamusoro zvemhando yechigadzirwa uye mhedzisiro yekuratidzira. Mukuita kwekurongedza, yechinyakare SMD tekinoroji haichakwanisa kusangana nezvinodiwa zvekushandisa zvemamwe mamiriro. Zvichienderana neizvi, vamwe vagadziri vakashandura yekurongedza track uye vakasarudza kuendesa COB nemamwe matekinoroji, nepo vamwe vagadziri vakasarudza kuvandudza tekinoroji yeSMD. Pakati pavo, GOB tekinoroji ndeye iterative tekinoroji mushure mekuvandudzwa kweSMD yekurongedza maitiro.
Saka, neGOB tekinoroji, ma LED anoratidza zvigadzirwa anogona kuwana yakakura maapplication? Ndeapi maitiro acharatidzwa nemusika wemangwana weGOB? Ngatitarisei!
Kubva pakuvandudzwa kweindasitiri yekuratidzira ye LED, kusanganisira kuratidzwa kweCOB, nzira dzakasiyana dzekugadzira uye dzekurongedza dzakabuda imwe mushure meimwe, kubva kune yakapfuura yakananga yekuisa (DIP) maitiro, kusvika kune yepamusoro gomo (SMD) maitiro, kusvika pakubuda kweCOB. kurongedza tekinoroji, uye pakupedzisira kusvika pakubuda kweGOB yekurongedza tekinoroji.
⚪Chii chinonzi COB yekurongedza tekinoroji?
COB kurongedza zvinoreva kuti inonamatira zvakananga chip kuPCB substrate kugadzira magetsi. Chinangwa chayo chikuru ndechekugadzirisa dambudziko rekupisa kupisa kwe LED kuratidza skrini. Kuenzaniswa neakananga plug-in uye SMD, hunhu hwayo kuchengetedza nzvimbo, kurerutswa kurongedza mashandiro, uye inoshanda yekupisa manejimendi. Parizvino, COB kurongedza kunonyanya kushandiswa mune zvimwe zvidiki-pitch zvigadzirwa.
Ndezvipi zvakanakira COB yekurongedza tekinoroji?
1. Ultra-chiedza uye yakatetepa: Zvinoenderana nezvinodiwa chaizvo nevatengi, PCB mabhodhi ane ukobvu hwe0.4-1.2mm anogona kushandiswa kuderedza huremu kusvika 1/3 yezvigadzirwa zvechinyakare, izvo zvinogona kuderedza zvakanyanya zvimiro, zvekufambisa uye mari yeinjiniya kune vatengi.
2. Anti-kudhumhana uye kudzvinyirirwa kuramba: COB zvigadzirwa zvakananga encapsulate LED chip munzvimbo concave yePCB board, uye ipapo kushandisa epoxy resin glue kuvharidzira uye kurapa. Kumusoro kwechigadziko chemwenje kunosimudzwa munzvimbo yakasimudzwa, iyo yakatsetseka uye yakaoma, inopesana nekupokana uye kupfeka.
3. Hombe yekuona kona: COB packaging inoshandisa shallow well spherical light emission, ine angle yekuona yakakura kudarika 175 degrees, pedyo ne180 degrees, uye ine zvirinani optical diffuse color effect.
4. Kugona kwakasimba kwekupisa kupisa: Zvigadzirwa zveCOB zvinoputira mwenje paPCB board, uye nekukurumidza kutamisa kupisa kwetambo kuburikidza nefoiri yemhangura paPCB board. Pamusoro pezvo, ukobvu hwemhangura foil yePCB board ine zvakaomesesa zvinodikanwa, uye kunyura kwegoridhe hakuzokonzeredze kudzikamisa mwenje. Naizvozvo, kune mwenje mishoma yakafa, iyo inowedzera zvakanyanya hupenyu hwemwenje.
5. Kupfeka-kusapfeka uye kuri nyore kuchenesa: Pamusoro penzvimbo yemwenje inotenderera kuita denderedzwa, iyo inotsvedzerera uye yakaoma, isingaite kudhumhana uye kusakara; kana pane imwe nzvimbo yakaipa, inogona kugadziriswa pfungwa nepoint; pasina mask, guruva rinogona kucheneswa nemvura kana jira.
6. Yese-mamiriro ekunze akanakisa maitiro: Inotora katatu kudzivirira kurapwa, ine yakatanhamara mhedzisiro yekusapinda kwemvura, mwando, ngura, huruva, static magetsi, oxidation, uye ultraviolet; inosangana nemamiriro ekunze-mamiriro ekunze ekushanda uye inogona kushandiswa zvakajairwa munzvimbo yetembiricha yemusiyano weminus 30 degrees to plus 80 degrees.
⚪Chii chinonzi GOB yekurongedza tekinoroji?
GOB packaging tekinoroji yekurongedza yakatangwa kugadzirisa nyaya dzekudzivirira dzemarambi e LED. Inoshandisa zvinhu zvepamberi zvakajeka kuvhara iyo PCB substrate uye LED yekurongedza unit kuti iite chengetedzo inoshanda. Izvo zvakaenzana nekuwedzera chidziviriro pamberi peiyo yekutanga LED module, nekudaro uchiwana mabasa edziviriro epamusoro uye kuwana gumi edziviriro zvinosanganisira kusapinda kwemvura, kunyorova, kukanganisa-proof, bump-proof, anti-static, salt spray-proof. , anti-oxidation, anti-blue light, uye anti-vibration.
Ndezvipi zvakanakira GOB kurongedza tekinoroji?
1. GOB process zvakanakira: Iyo inodzivirira yakanyanya LED kuratidza sikirini inokwanisa kuwana zvidziviriro zvisere: kusapinda mvura, kunyorova, anti-kurovera, guruva-proof, anti-corrosion, anti-blue mwenje, anti-munyu, uye anti- static. Uye hazvizove nemigumisiro inokuvadza pakupisa kupisa uye kurasikirwa kwekupenya. Yenguva refu yakaomesesa kuyedzwa kwakaratidza kuti kudzivirira glue kunyange kunobatsira kubvisa kupisa, kuderedza necrosis chiyero chemarambi mabhero, uye inoita kuti skrini igadzikane, nekudaro ichiwedzera hupenyu hwesevhisi.
2. Kuburikidza neGOB process process, mapikiseli egranular ari pamusoro pebhodhi rechiedza chepakutanga akashandurwa kuita bhandi remwenje rakazara, achiona shanduko kubva padanho rechiedza kuenda kutsime rechiedza. Chigadzirwa chacho chinoburitsa mwenje zvakanyanya kuenzana, mhedzisiro yekuratidzira inojeka uye yakajeka, uye kona yekuona yechigadzirwa inovandudzwa zvakanyanya (zvese zvakatwasuka uye zvakadzika zvinogona kusvika kunosvika 180 °), zvinobudirira kubvisa moiré, kuvandudza zvakanyanya kusiyana kwechigadzirwa, kuderedza kupenya uye kupenya. , uye kuderedza kuneta kwekuona.
⚪Ndeupi musiyano uripo pakati peCOB neGOB?
Musiyano uripo pakati peCOB neGOB uri kunyanya mukuita. Kunyangwe iyo COB package ine nzvimbo yakati sandara uye inodzivirirwa zviri nani pane yechinyakare SMD package, iyo GOB package inowedzera glue yekuzadza maitiro pamusoro pechidzitiro, izvo zvinoita kuti mwenje wemwenje we LED ugadzikane, unoderedza zvakanyanya mukana wekudonha, uye ine kugadzikana kwakasimba.
⚪Ndeipi ine zvakanakira, COB kana GOB?
Iko hakuna mwero weiyo iri nani, COB kana GOB, nekuti pane zvakawanda zvinhu zvekutonga kana chirongwa chekurongedza chakanaka kana kwete. Chinokosha ndechekuona zvatinokoshesa, kungave kushanda kwemarambi e LED kana kudzivirira, saka tekinoroji yega yega yekurongedza ine zvayakanakira uye haigone kuve yakajairwa.
Kana isu tichinyatso sarudza, kana kushandisa COB kurongedza kana GOB kurongedza kunofanirwa kutariswa pamwe chete nezvinhu zvakazara senge yedu yekumisikidza nharaunda uye nguva yekushanda, uye izvi zvine chekuitawo nekudzora mutengo uye kuratidza maitiro.
