1. Sulfidation, chlorination thiab bromination.
Cov nyiaj-plated txheej ntawm LED zaub bracket tiv tauj nrog sulfur-muaj cov ntsiab lus los tsim cov nyiaj sulfide, thiab kev sib cuag nrog nitrogen, chlorine, thiab bromine gases los tsim lub teeb-sensitive silver halide, tag nrho cov uas yuav ua rau cov zaub ua dub thiab poob. Sulfur chlorine / bromination / bromination / bromination tuaj yeem tshwm sim hauv txhua qhov txuas ntawm kev tsim khoom, khaws cia, kev laus, thiab kev siv LEDs. Tom qab lub vijtsam dub tau kuaj pom tias yog sulfur / chlorine / bromination, tus neeg siv khoom yuav tsum xaiv cov phiaj xwm tshem tawm cov sulfur tshwj xeeb raws li cov txheej txheem ntawm sulfur / chlorine / bromination. Cov khoom siv tshuaj sulfur / chlorine / bromine los ntawm Jinjian suav nrog: sulfur / chlorine / bromine los ntawm cov teeb, sulfur / bromine los ntawm cov teeb, sulfur / bromine los ntawm cov khoom siv hluav taws xob, sulfur / chlorine / bromine los ntawm cov khoom siv, sulfur / bromine los ntawm cov chaw ua haujlwm ntim khoom, Tshem tawm sulfur / bromine hauv reflow soldering Rhiav. Txij li thaum cov sulfur / chlorine / bromine-muaj roj nkag mus rau hauv lub vijtsam zaub los ntawm qhov sib txawv ntawm cov silica gel lossis lub bracket, Jinjian kuj tau qhia txog kev ntsuas huab cua nruj ntxiv los pab cov neeg siv khoom txhim kho cov cai rau cov khoom siv.
2. Oxidation.
Nyiaj tau yooj yim hnov mob nrog oxygen los tsim cov nyiaj dub oxide hauv qab cua sov thiab cov av noo siab. Nws tau txiav txim siab tias yog vim li cas rau blackening ntawm cov zaub yog tias tom qab cov nyiaj plating yog oxidized, Jinjian yuav qhia cov neeg siv khoom los xyuas cov huab cua nruj ntawm cov zaub thiab cov khoom siv teeb pom kev zoo kom tshem tawm txoj hauv kev ntawm cov dej noo nkag.
3. Carbonization.
Los ntawm cov kev paub dhau los, cov khoom siv tsis raug ntawm rau qhov loj raw khoom ntawm LED zaub thiab cov txheej txheem tsis xws luag ntawm peb lub ntim loj yuav ua rau cov zaub kub siab dhau, ua rau ib nrab lossis tag nrho blackening, thiab carbonization ntawm cov zaub. LED teeb lub teeb hluav taws xob tsim hluav taws xob tsis tsim nyog, cov thermal conductivity ntawm cov khoom siv hluav taws xob tsis zoo, cov khoom siv hluav taws xob tsim tsis tsim nyog, thiab ntau qhov kev cuam tshuam rov qab tuaj yeem ua rau cov zaub yog carbonized. Yog li ntawd, thaum Jinjian pib txiav txim siab tias yog vim li cas rau blackening ntawm cov zaub yog carbonization, nws yog pom zoo kom cov neeg muas zaub * soj ntsuam txoj kev ntawm lub LED zaub los yog teeb tsis ua hauj lwm, dissecting lub zaub / teeb, thiab nrhiav tau lub hauv paus ntawm qhov tsis xws luag. los yog siab thermal kuj.
4. Tshuaj incompatibility.
Lub blackening ntawm LED zaub kuj yuav tshwm sim los ntawm cov tshuaj lom neeg ua paug, uas feem ntau tshwm sim nyob rau hauv lub teeb kaw nrog me me los yog tsis muaj cua txaus. Tom qab paub meej tias qhov blackening ntawm cov zaub yog ib qho teeb meem tshuaj sib raug zoo, cov neeg siv khoom raug qhia kom xyuas seb cov khoom siv hauv lub teeb puas muaj tshuaj lom neeg tsis sib xws, thiab nrhiav cov ntaub ntawv uas tsis sib haum nrog cov zaub. Muaj teeb meem ntau zaus. Txawm li cas los xij, qhov blackening ntawm cov zaub tsuas yog qhov tshwm sim ntawm qhov chaw, thiab cov vulcanization, chlorination, bromination, oxidation, carbonization, thiab tshuaj incompatibility ntawm LED zaub yuav ua rau LED zaub dub. Thaum tsis muaj cov cuab yeej kuaj thiab cov neeg ua haujlwm, feem ntau cov tuam txhab LED feem ntau tso siab rau kev paub dhau los thiab kev kwv yees thaum txheeb xyuas qhov ua tsis tiav ntawm blackening, thiab tsis muaj cov ntaub ntawv tshawb fawb.
