Kev ceev faj rau kev tiv thaiv kev ua kom qhuav hauv SMT cov txheej txheem tsim khoom ntawm LED daim ntawv thov khoom
Kev ceev faj rau kev tiv thaiv kev ua kom qhuav hauv SMT cov txheej txheem tsim khoom ntawm LED daim ntawv thov khoom
Hauv SMT cov txheej txheem tsim khoom ntawm LED daim ntawv thov cov khoom lag luam, kev ua kom muaj vulcanization feem ntau yuav tshwm sim hauv cov txheej txheem rov ua dua tshiab. Los ntawm ntau qhov xwm txheej tsis zoo uas tau tshwm sim, Jin Jian qhia pom tias lub vijtsam nyiaj stent raug ua kom hnyav, thiab qhov nrawm yog cuam tshuam ncaj qha rau cov ntsiab lus leej faj, kub, thiab sijhawm. Cov txheej txheem rov ua dua tshiab yog qhov kub thiab txias ib puag ncig ib puag ncig, thiab muaj ntau yam khoom siv uas muaj cov leej faj tuaj yeem ntsib. Thaum lub sijhawm tshuaj xyuas txheej txheem ntawm GMKJ LED, nws tau pom tias muaj cov ntaub ntawv sau tseg ntawm cov tshuaj leej faj nyob hauv cov tshuaj txhuam hniav muab tshuaj ntxuav dej thiab lwm yam txhaws nplaum ntawm PCB cov laug cam. Thaum lub sijhawm SMT ua haujlwm, cov ntaub ntawv no yuav rov ua dua nrog LED. Tom qab reflowing rau ib lub sijhawm, cov nyiaj plated ib feem ntawm lub bracket yuav dhau mus rau sab hauv. Qhov laj thawj tseem ceeb yog tias cov tshuaj uas muaj cov leej faj nkag mus rau hauv LED thaum txheej txheem rov ua dua, ua rau cov nyiaj yog Vulcanization, ua rau cov khoom lag luam tsis ua haujlwm.
Piv txwv li, los ntawm kev tshuaj xyuas kev sib xyaw ntawm MCPCB cov ntawv hauv ntau qhov ntawm GMKJ LED yav dhau los, ntau daim ntawv tsim tawm ntawm kev ua lag luam muaj ntau qib sib txawv ntawm cov leej faj, txawm hais tias MCPCB cov tuam ntxhab yuav ntxuav cov ntawv thaum txheej txheem tshem tawm cov ntsiab lus. Sulfur thiab acid-muaj tshuaj hnyav hnyav nyob hauv, tab sis nws nyuaj rau tshem tawm lawv hauv cov txheej txheem ntau lawm. Hauv qhov pom ntawm qhov tseeb tias leej faj tseem muaj zog ntau nyob rau ib puag ncig kub thaum SMT kev ua haujlwm, MCPCB pawg thawj coj tuaj yeem ua tiav ua ntej los ntawm lub tshuab ua kom sov rov qab kub (li 230 degrees) ua ntej ntxuav qhov chaw (haus cawv, thiab lwm yam) ua ntej kev txhim kho saum npoo kom txo tau MCPCB cov khoom siv Sulfur cov ntsiab lus ntawm cov disc thiab txheej txheej. Yog tias cov txheej txheem tsis raug tso cai, PCB saum npoo tuaj yeem ntxuav ncaj qha ua ntej SMT, thiab cov khoom nto yuav tsum tau ntxuav ib zaug tom qab rov ua tiav. Lub rooj tsavxwm saum npoo av thiab cov laug sib txuas tau raug ntxuav kom txo qhov tshwm sim ntawm LED vulcanization. Thaum ntxuav, koj yuav tsum xaiv kom tsis txhob ua tshuaj sulfur thiab tsis muaj lwm yam kua qaub los ntxuav Liu
Them nyiaj tshwj xeeb rau cov tshuaj txhuam hniav ntawm no. Cov tshuaj txhuam hniav yog cov txheej txheem nyuaj, uas yog sib xyaw hmoov sib tov, dej ntws thiab lwm yam ntxiv. Cov kuab tshuaj thiab qee qhov ntxiv ntawm cov tshuaj muab tshuaj txhuam yuav ua kom sov nyob rau hauv qhov kub thiab txias ntawm cov laug, thiab cov kuab tshuaj no yuav nkag mus los ntawm qhov khoob ntawm LED teeb hlaws lossis cov pores ntawm silica gel. Qhov sib xyaw ua ke hauv cov tshuaj txhuam hniav yog qhov nyuaj dua. Cov tshuaj ua kom muaj zog feem ntau muaj ob peb lub halogen lossis cov organic acids. Nws tuaj yeem tshem tawm cov yeeb yaj kiab oxide saum npoo ntawm cov hlau yaj, txo qhov nro ntawm cov laug, thiab ua kom cov kab laug sab kis tau sai ntawm cov hlau yaj. nto. Cov halogens feem ntau siv yog chlorine thiab bromine. Kev muaj tshuaj chlorine thiab bromine tuaj yeem yooj yim ua rau chlorination, bromination thiab tshuaj tsis sib xws ntawm lub teeb hlaws.
Yog li ntawd, GMKJ LED pom zoo tias cov chaw tsim hluav taws xob LED ua cov kev tshuaj xyuas tsis tu ncua ntawm PCB cov laug cam, cov khoom siv, thiab lwm yam khoom txhawb nqa kom tsis txhob muaj cov tshuaj muaj tooj liab nyob hauv PCB cov laug cam. Tom qab kev sib txuas ntawm PCB rov ua tiav, txoj haujlwm sib koom ua ke raug ntxuav kom tshem tawm lossis txo qis qhov seem. Tsis txhob siv cov kua qaub uas muaj cov kua qaub thiab cov kuab tshuaj rau cov tshuaj ntxuav.
Ib qho ntxiv, thaum lub sijhawm SMT ua haujlwm, nws yog ib qho tsim nyog los tiv thaiv kev siv cov khoom uas muaj cov leej faj los ua kom cov LED ua rau vulcanization. Piv txwv li, thov tsis txhob siv cov tshuaj sulfur lossis halogen uas muaj xws li hnab looj tes roj hmab, cov menyuam ntiv tes ntiv tes, cov hlua roj hmab, cov roj hmab los tiv thaiv cov ntaub pua tsev zoo li qub, cov tub lim, cov iav iav, cov kua nplaum kub, thiab lwm yam kom tiv tauj LED thaum lub qhov muag thiab kev txhim kho ntawm LED. ; Nws kuj tseem tsim nyog los tiv thaiv kev siv cov khoom sib dhos thiab cov cav tov vulcanized; nws yog qhov zoo tshaj los tsim cov kab sib cais tsis pub dawb SMT cov kab tsim khoom lossis cov rooj cob qhia tsim khoom kom ntseeg tau tias cov khoom lag luam tsis raug nplua thaum lub sijhawm txheej txheem ua cov khoom lag luam SMT: tsis tu ncua ntxuav lub tshuab cua sov rov qab thiab Dehumidification qhov cub: thiab tswj kev ua haujlwm ib puag ncig ntawm LED lossis Cov khoom siv LED thaum siv vuam, ua haujlwm thiab thov, uas muaj txiaj ntsig zoo los txo lossis txawm tias tshem tawm txoj kev pheej hmoo ntawm leej faj lossis halogen raug rau LED.
