Puas yog nws zoo dua los siv rosin lossis solder paste rau hluav taws xob soldering hlau? Qhov sib txawv thiab ua haujlwm ntawm rosin thiab solder paste
Tseem muaj qhov sib txawv ntawm solder paste thiab rosin. Rosin yog ib qho khoom siv crystalline uas muab rho tawm los ntawm cov resin secreted los ntawm ntoo thuv. Dab tsi yog feem ntau hu ua solder siab yuav yog ob yam sib txawv. Ib qho tuaj yeem siv los ua flux thiab lwm qhov tuaj yeem siv ncaj qha ua solder.
Ua ntej qhia rosin. Nws yog rosin secreted los ntawm ntoo thuv, uas yog me ntsis zoo li cov roj hmab ntawm cov ntoo roj hmab. Tom qab ntuj rosin tiav lawm, turpentine thiab rosin tuaj yeem tsim tau. Rosin yog ib tug zoo heev flux, uas yog dav siv nyob rau hauv lub soldering txheej txheem ntawm electronics kev lag luam vim nws tsis-corrosion thiab zoo rwb thaiv tsev zog. Feem ntau siv solder hlau yog ib tug hollow core qauv uas muaj rosin.
Tab sis cov khoom rosin tsis yooj yim rau siv ib leeg, yog li nws tau ua rau muab tshuaj txhuam. Qhov no yuav tsum tau siv lwm cov kuab tshuaj thiab cov tshuaj ntxiv, kom cov tshuaj txhuam hniav tsis qhuav sai rau kev siv yooj yim. Txawm li cas los xij, nws kuj tseem tuaj yeem txo cov khoom insulating ntawm flux, thiab qee qhov kuj muaj qee qhov kev txhim kho corrosion. Yog li ntawd, tsis txhob siv cov tshuaj txhuam hniav nrog cov rwb thaiv tsev tsis zoo thaum siv cov khoom siv hluav taws xob thiab cov ntawv luam tawm. Yav dhau los, kuv tau siv cawv kom yaj rosin li flux. Thaum soldering, cawv evaporates tam sim ntawd, thiab tus so yog ntshiab rosin, uas yuav tsis ua corrosion rau hluav taws xob Cheebtsam thiab yuav tsis xau hluav taws xob. Cia li ntxiv cawv los yog nws yuav nplaum sai heev.
Lwm hom hu ua solder paste (tseem hu ua tin paste) yog ua los ntawm tin hmoov thiab flux, uas yog nyiaj grey. Nws yog siv los ua solder nyob rau hauv cov txheej txheem reflow soldering kom tiav cov soldering ntawm SMD Cheebtsam. Ua ntej soldering, siv cov tin muab tshuaj txhuam rau ntawm lub ncoo los ntawm kev khawb thiab tso cov khoom, thiab tom qab ntawd dhau los ntawm qhov cub reflow, cov tshuaj nplaum yuav yaj rau hauv solder thiab ua tiav SMD soldering nrog kev pab los ntawm cov khoom xyaw.
Ob qho tshuaj txhuam hniav no yooj yim kom paub qhov txawv, tsuas yog cov xim sib txawv thiab qhov hnyav kuj txawv. Cov nyiaj muab tshuaj txhuam ua los ntawm tin hmoov yog hnyav heev thiab tus nqi kim dua.
