COB (Chip on Board) Madhizaini eLED, sechinotevera-tekinoroji yekuratidza chizvarwa, anoshandiswa zvakanyanya mumhando yepamusoro-yekupedzisira maapplications nekuda kwekukwira kwawo-kusanganiswa kwe density, musiyano mukuru, uye dziviriro yakanaka. Nekudaro, maitiro avo akaomarara ekugadzira anoisa kunyanya kukoshesa kudzora kwemhando, izvo zvinokanganisa zvakananga kuvimbika kwechigadzirwa uye hupenyu hwehupenyu.
Material uye chip screening ndizvo zvakakosha mukutonga kwemhando. Yepamusoro{{1}yemhando ye LED machipisi nemidziyo yesubstrate yakakosha pakuona kuti chiratidziro chinoshanda uye zvinofanirwa kuongororwa zvine hungwaru zvinopinda, kusanganisira kuyedzwa zvinhu zvakaita sechiedza chinopenya, kusimba kwewavelength, uye kushivirira kwemafuta, kudzivirira kutadza kunotevera nekuda kwehurema.
Encapsulation process control inokanganisa zvakananga kugadzikana uye mamiriro ekunze kuramba kweCOB kuratidza. Maitirwo akaita semabonding, wire bonding, uye kuburitsa glue zvinofanirwa kuitwa munzvimbo isina huruva-, pachishandiswa midziyo inongozviitira kuti inyatso kudzora huwandu hweglue uye tembiricha yekusodha kudzivirira matambudziko akaita semajoini anotonhora emasoja nekutsemuka. Pamusoro pazvo,-kuvimbika kwekuvharisa zvinhu, senge epoxy kana silicone, zvinoshandiswa kuwedzera mwando uye kudzivirira UV.
Pixel pitch uye optical consistency zviratidzo zvakakosha zvekuratidzira kuita. COB zviratidzo zvinowanzoita-pitch dhizaini yakanaka, inoda tekinoroji yekuenzanisa kuti ione kupenya kwakafanana uye ruvara kudzivirira pixelation kana zvigadzirwa. Panguva yekugadzira, michina yekuongorora yakasarudzika inoshandiswa kuita nzvimbo-ne{4}}kugadziriswa kwepoinzi pane yega yega module kuti ive nechokwadi chekuenderana pachiratidziro chose.
Kuchembera uye kuvimbika kuyedzwa ndiwo mutsara wekupedzisira wekudzivirira usati watumirwa. Zvigadzirwa zvinoedzwa zvakasimba, kusanganisira tembiricha yepamusoro uye mwando, kupisa kwemafuta, uye nguva yekushanda yakawedzerwa, kutevedzera kushanda munzvimbo dzakanyanyisa, kuongorora kusakundikana nguva isati yakwana, uye kuona kuti{1}}kugadzikana kwenguva refu.
Muchidimbu, kudzorwa kwemhando ye COB LED kuratidzwa kunofanirwa kuve kwakanyatso mukuita kwese, kubva pakusarudzwa kwezvinhu kusvika pakugadzirisa optimization uye kuomarara kuyedzwa, kuti uwane chiyero pakati pekuvimbika kwepamusoro nemhando yepamusoro yekuratidzira, kusangana nemusika unodiwa-kuratidzwa kwemhando yepamusoro.
