Kusviba kweLED kuratidza skrinichinhu chinowanzoitika.Nhasi, ngatitarisei zvikonzero zvakati wandei zvekusviba kwayo.
1. Sulfurization, chlorination, uye bromination
Sirivha yeplating layer iri pa LED inoratidzira bracket ichagadzira sirivheri sulfide kana yasangana nesarufa-ine gasi, uye kana yasangana ne acidic nitrogen-ine chlorine uye bromine gasi, inoburitsa photosensitive sirivheri halide, izvo zvinokonzeresa. chitubu chechiedza kuita chitema chikatadza.Sulfur / chlorine / bromination yemwenje masosi inogona kuitika mune yega nhanho yekugadzira, kuchengetedza, kuchembera, uye kushandiswa kwe LED mwenje masosi uye mwenje.Mushure mekuonekwa kuti ane sulfur/chlorine/bromination nekuda kwekusviba kwechiedza chechiedza, mutengi anofanira kusarudza chirongwa chekubvisa sarufa zvichienderana nedariro panoitika sulfur/chlorine/bromination.Parizvino, mapurojekiti ekuona sarufa/chlorine/bromine akatangwa neJinjian anosanganisira: sarufa yemwenje/chlorine/bromine (kusanganisira yakavakirwa mukati.magetsi), mwenje sarufa/chlorine/bromine (kusingabatanidzi simba rekunze), magetsi ekushandisa sarufa/chlorine/bromine, anobatsira zvinhu sarufa/chlorine/bromine, kurongedza workshop sarufa/chlorine/bromine, mwenje workshop sulfur/chlorine/bromine, uye reflow soldering workshop sulfur/chlorine/bromine.Nekuda kwekuti magasi ane sulfuri, chlorine, uye bromine anogona kupinda mukati mechiedza chechiedza kuburikidza nemakwapa ari musilicone kana mabhuraketi, Jinjian yakatangawo chirongwa chekuongorora kusapinda kwemhepo kuti ienderere mberi nekubatsira vatengi kuvandudza zvavanoda kune zvigadzirwa zvemwenje.
2. Oxidation
Sirivha inopindirana zviri nyore neokisijeni munzvimbo yekupisa uye munyoro, ichigadzira dema sirivheri oxide.Mushure mekusimbisa kuti chikonzero chekudzima kwemwenje sosi ndeye oxidation yesirivheri plating layer, Jin Jian anozopa zano kuti mutengi aenderere mberi nekutarisa kusimba kwemhepo pane mwenje sosi uye mwenje kubvisa nzira yekupinza hunyoro.
3. Carbonization
Zvichienderana neruzivo, hurema hwezvinhu muzvinhu zvitanhatu zvakakura zvemagetsi emwenje e LED (machipisi, mabhuraketi, yakasimba crystal glue, waya dzekubatanidza, fluorescent poda, uye kurongedza glue) uye kukanganisa kwemaitiro mumatatu makuru ekurongedza (solid crystal, wiring, uye gluing) zvese zvinogona kutungamira kune yakanyanya kupisa tembiricha munzvimbo yechiedza, zvichikonzera kusviba kwenzvimbo kana kwese uye carbonization yechiedza sosi.Isinganzwisisike kupisa kupisa dhizaini yemarambi eLED, yakaderera yekupisa conductivity yezvinhu zvinopisa kupisa, dhizaini isina musoro yemagetsi, uye yakawandisa reflow soldering hurema inogona zvakare kukonzera carbonization yechiedza sosi.Naizvozvo, kana Jinjian achinge asimbisa kuti chikonzero chekudzima kwemwenje sosi ndeye carbonization, inozoratidza kuti mutengi ateedzere mwenje we LED sosi kana mwenje kutadza kuongorora nzira, patsanura iyo mwenje sosi / mwenje, uye uone kunobva kukanganisa kana high thermal resistance.
4. Kusapindirana kwemakemikari
Kusviba kwemagetsi emwenje e LED kunogonawo kukonzerwa nekusvibiswa kwemakemikari, uye chiitiko ichi chinosviba chinowanzoitika mumarambi akavharwa asina kana kuyerera kwemhepo.
Kana isu tikasangana nemamiriro ezvinhu apo iyo LED inoratidzira skrini inoshanduka nhema, tinogona kuongorora zvikonzero chimwe nechimwe uye kugadzirisa.
