Musiyano uripo pakati peGob neCOB ndeupi?

Munyika ye tekinoroji ye LED, mazwi ekuti GOB na COB anowanzo kurukurwa kana tichifunga nezve ma LED modules anoshanda zvakanyanya kune akasiyana mashandisirwo. Aya matekinoroji maviri ekurongedza ma LED akakosha pakuona kuti mwenje ye LED inogara kwenguva refu, inoshanda zvakanaka, uye inopenya. Zvisinei, kunyangwe GOB na COB zvese zvichireva nzira dzekuisa ma LED chips, zvakasiyana zvakanyanya maererano nechimiro, mashandisirwo, uye mashandiro.

A. Chii chinonzi COB (Chip on Board)Chinovhara chakagadzirwa ne LED?

COB (Chip on Board) tekinoroji inoshandiswa kuisa machipisi akawanda e LED zvakananga pane substrate pasina chero kurongedza kwechinyakare. MuCOB LED yakajairika, machipisi akawanda e LED anonamirwa pabhodhi rimwe chete kana substrate, izvo zvinoita kuti dhizaini ive diki uye inoshanda. COB LEDs dzinopa chiedza chakawanda munzvimbo diki, zvichiita kuti dzive mhinduro yakanaka kune mashandisirwo emwenje inoshanda zvakanyanya uye yekutengeserana.

1. Maumbirwo uye Nheyo yeKushanda:

MuCOB LED, machipisi e LED ega ega ndeaya:

- Yakaiswa zvakananga pachigadziko: Machipisi e LED anoiswa pachigadziko, icho chinowanzova chinhu chine thermal conductivity yakanaka, senge aluminium, kubatsira kubvisa kupisa zvinobudirira.

- Yakabatana nemagetsi: Machipisi acho anosungirirwa zvakananga kubhodhi, zvichibvumira kufamba kwemagetsi zvakanaka uye kugoverwa kwesimba.

- Kutarisira kupisa: MaCOB LED anowanzo shandisa maPCB esimbi (MCPCB), ayo anobatsira mukuderedza kupisa uye kuwedzera hupenyu hwemaLED.

Tekinoroji yeCOB inonyanya kufarirwa muzvirongwa zveCommercial display, zvakaita sekushambadzira mukati meimba, kushambadzira panze, uye musangano, nekuti inobvumira kupenya kwakanyanya uye kufanana kwechiedza kwakanaka.

(1) Kushanda Nesimba Kwakanyanya: Ma COB LED anogadzira mwero wekupenya kwakanyanya uye anopa chiedza chakanaka, zvichiita kuti akwanise kuvhenekerwa zvakanyanya.

(2) Kutarisira Kupisa Zviri Nani: Kuisa machipisi zvakananga pamidziyo inofambisa kupisa kunoita kuti kupisa kuparare zvakanaka, zvichideredza njodzi yekupisa zvakanyanya uye kuvandudza kugara kwenguva refu kwemaLED.

(3) Dhizaini Yakabatana: Machipisi e LED akawanda akabatanidzwa pamwe chete, zvichiita kuti chiedza chive chakawanda munzvimbo diki, izvo zvakakodzera kushandiswa kunoda chiedza chakasimba, chakafanana.

(4) Kugara Nekutendeseka: Ma COB LED anowanzo gara kwenguva refu kupfuura ma SMD LED ega ega, sezvo machipisi akaiswa zvakasimba uye asingakuvadzi zvakanyanya kubva mukuzunguzika kana kuvhunduka.

3. Zvakashata zveCOB LEDs:

(1) Mutengo Wakakwira: Ma COB LED anowanzo kudhura zvakanyanya nekuda kwemaitiro ekugadzira epamusoro uye zvinhu zvemhando yepamusoro zvinoshandiswa pakugadzirisa kupisa.

(2) Kuchinjika Kushoma: MaCOB LED anowanzo shandiswa mumabasa akaomarara (akadai sekugadzirisa magetsi akasimba) uye haana kuchinjika semaSMD LED, anogona kuiswa pamaPCB anochinjika.

B. Chii chinonzi GOB (Glue on Board)?

GOB (Glue on Board) itekinoroji itsva yekurongedza ma LED inovandudza tekinoroji yechinyakare yeCOB nekushandisa imwe coating yekudzivirira kana guruu pa LED chip, iyo inovandudza kugara kwenguva refu uye kuvimbika kwe LED. GOB yakagadzirirwa kudzivirira kukuvara kwema LED chips kubva kune zvimwe zvinhu zvakaita seguruva, hunyoro, uye kudedera.

Mugadziriro yeGOB, mushure mekunge machipisi eLED aiswa paPCB (sekunge mugadziriro yeCOB), jira rekudzivirira re epoxy kana silicon glue rinoiswa pamusoro. Rudzi urwu runoshanda ku:

- Dzivirira machipisi e LED kubva mukukuvadzwa kwezvakatipoteredza (guruva, hunyoro, ngura).

- Wedzera kuburitswa kwechiedza uye kushanda zvakanaka nekuderedza kubatwa kwechiedza kunogona kuitika kana chiedza chaiswa pachena.

- Wedzera kuvimbika nekuona kuti machipisi e LED anoramba ari panzvimbo yawo uye anoshanda kwenguva yakareba, kunyangwe mumamiriro ezvinhu akaoma.

Guruu rinoshandiswa mu tekinoroji yeGOB rinobatsirawo kuti chiedza chifanane uye ruvara ruve rwakafanana, izvo zvakakosha mukushandiswa kwakafanana Zviratidzo zve LED uye zviratidzo zvikuru.

1. Maumbirwo uye Nheyo yeKushanda:

- Machipisi e LED akaiswa pa substrate (senge PCB) sezviri muCOB setup yakajairika.

- Guruu kana epoxy zvinoiswa pamusoro pemachipisi kuti zvidzivirire uye zvivharwe, zvichivandudza mashandiro emodule.

- Kudzivirirwa kuri nani kwezvakatipoteredza: Guruu iri rinoita chipingamupinyi chinochengetedza hunyoro, guruva, nezvimwe zvinosvibisa zvinogona kukanganisa mashandiro echip nekufamba kwenguva.

GOB inowanzoshandiswa muzviratidziro zvekunze uye munzvimbo umo ma LED anogona kusangana nemamiriro ekunze, akadai sezviratidziro zvekunze, mwenje yemumugwagwa, uye masisitimu emwenje eindasitiri akasimba.

2. Mabhenefiti eGOB LEDs:

(1) Kugara Kwakasimba: Glue iri rinodzivirira rinoita kuti machipisi e LED adzivirirwe zviri nani kubva kunjodzi dzezvakatipoteredza, zvichiita kuti maGOB LED akwanise kushandiswa panze uye mumaindasitiri.

(2) Kugoverwa Kwechiedza Zviri Nani: Guruu rinogona kubatsira kunatsiridza kupararira kwechiedza uye kuderedza kuoneka kwemavara matema kana kubuda kwechiedza kusina kuenzana, zvichiita kuti chiedza chive chakafanana.

(3) Kuramba Hunyoro neGuruva: Tekinoroji yeGOB inowedzera kuramba kwe LED kuhunyoro, guruva, nezvimwe zvinosvibisa, zvichiita kuti irambe iripo uye ichivandudza mashandiro ayo munzvimbo dzakaoma.

(4) Kuvimbika Kwakawedzerwa: Nekubatanidza machipisi e LED panzvimbo yawo nechikamu chekudzivirira, maGOB LED haawanzo kukuvara nemasimba ekunze, akadai sekuzunguzika kana kuvhunduka.

3. Zvakashata zveGOB LEDs:

(1) Mutengo Wakakwira: Kufanana nemaCOB LED, maGOB LED anodhura zvakanyanya nekuda kwematanho ekuwedzera ekugadzira nezvinhu zvinoshandiswa mukuita uku.

(2) Kuchinjika Kushoma: Kufanana nemaCOB LED, maGOB LED anowanzo shandiswa munzvimbo dzakasimba uye anogona kusachinjika zvakanyanya kune mashandisirwo anochinjika.

(3) Kurasikirwa Kunogona Kuitika: Guruu iri rinogona dzimwe nguva kukonzera kudzikira kudiki kwekushanda kwechiedza, sezvo richigona kutora chiedza, kunyange zvazvo mhedzisiro iyi iri shoma kana tichienzanisa nemabhenefiti.
