Mitsetse yemwenje ye LED yakabuda zvishoma nezvishoma muindasitiri yekushongedza nekuda kwekureruka kwavo, kuchengetedza simba, kupfava, hupenyu hurefu, uye kuchengeteka.Saka chii chandinofanira kuita kana mwenje we LED usingavheneke?Iyo inotevera LED strip mugadziri Nanjiguang inosuma muchidimbu nzira dzekugadzirisa dze LED mitsetse.
1. Kukuvadza kwekushisa kwepamusoro
Iyo yakakwirira tembiricha yekudzivirira ye LED haina kunaka.Naizvozvo, kana tembiricha yekushongedza uye nguva yekushongedza ye LED isinganyatso kudzorwa panguva yekugadzira uye kugadzirisa maitiro, iyo LED chip ichakuvadzwa nekuda kwekunyanya-yakakwira tembiricha kana kuenderera kwekushisa kwepamusoro, izvo zvichaita kuti tambo ye LED ikuvadzwe.Kunyepedzera kufa.
Solution: ita basa rakanaka mukudzora tembiricha ye reflow soldering uye soldering iron, shandisa munhu akakosha ane mutoro, uye yakakosha faira manejimendi;iyo solder iron inoshandisa tembiricha-inodzorwa solder simbi kuti ibudirire kudzivirira iyo solder iron kubva pakupisa iyo LED chip pakupisa kwakanyanya.Zvinofanira kucherechedzwa kuti solder simbi haigoni kugara pamusoro LED pini kwemasekonzi gumi.Zvikasadaro zviri nyore kwazvo kupisa iyo LED chip.
Chechipiri, static magetsi anopisa
Nekuti LED inhengo ye electrostatic sensitive component, kana iyo electrostatic dziviriro isina kuitwa zvakanaka panguva yekugadzira, iyo LED chip ichapiswa nekuda kwemagetsi akamira, izvo zvinokonzeresa kufa kwenhema kweiyo LED strip.
Solution: Simbisa electrostatic dziviriro, kunyanya simbi inodhaka inofanira kushandisa anti-static soldering iron.Vese vashandi vanosangana ne LEDs vanofanirwa kupfeka magirovhosi e-anti-static uye mhete dzemagetsi zvinoenderana nemirairo, uye maturusi uye zviridzwa zvinofanirwa kuve zvakadzika pasi.
3. Unyoro hunoputika pasi pekushisa kwepamusoro
Kana iyo LED package yakafumurwa kumhepo kwenguva yakareba, inotora unyoro.Kana isina kubviswa humidified isati yashandiswa, ichaita kuti hunyoro huri mupakeji ye LED iwedzere nekuda kwekupisa kwakanyanya uye nguva yakareba panguva yekutenderera solder process.Iyo LED package inoputika, izvo zvisina kunanga zvinoita kuti iyo LED chip iwedzere kupisa uye kuikuvadza.
Solution: Nzvimbo yekuchengetedza ye LED inofanirwa kugara ichipisa uye humidity.Iyo isina kushandiswa LED inofanirwa kubikwa muchoto paanenge 80 ° kwe6 ~ 8 maawa ekubvisa humidification isati yashandiswa inotevera, kuve nechokwadi kuti iyo yakashandiswa LED haizove nechero Moisture absorption phenomenon.
4. short circuit
Mazhinji ma LED mitsetse anoburitsa zvisina kunaka nekuti mapini e LED ane mapfupi-akatenderedzwa.Kunyangwe kana marambi e LED akachinjwa, anozopfupika-kutenderera zvakare kana asimbiswa zvakare, izvo zvinopisa machipisi e LED.
Mhinduro: Tsvaga chikonzero chaicho chekukuvadza munguva isati yagadziriswa, usatsiva iyo LED nekukasira, kugadzirisa kana kutsiva zvakananga iyo yose LED strip mushure mekutsvaga chikonzero chepfupi dunhu.
