Lub peev xwm lam ua lag luam niaj hnub no tseem ceeb heev rau cov xov tooj cua amateurs thiab cov kws ua ntoo uas kho cov cuab yeej hauv tsev. Txawm li cas los xij, lub peev xwm los tiv thaiv cov hlau soldering yuav tsis cuam tshuam nrog yuav luag txhua tus neeg sawv cev ntawm kev sib deev muaj zog, vim tias muaj ntau yam xwm txheej tuaj yeem tshwm sim hauv lub neej. Ib qho ntxiv, kev kawm paub ham yog yooj yim zoo nkauj, thiab nws tsis siv sijhawm ntev.
Cov hauv paus thiab lus
Ua ntej tshaj plaws, koj yuav tsum paub txog qee cov lus tshwj xeeb. Muag nws tus kheej yog txheej txheem ntawm kev koom nrog koom nrog ob ntu siv lub fusible alloy. Cov alloy no, lossis “solder,” feem ntau muaj qhov chaw ua kom ntuag qis dua li cov khoom nws koom nrog. Feem ntau, cov hmoov txhuas-yeeb yaj kiab tau siv, yaj thaum kub txog 220 ° C.
Ua ntej ua ntawv thov cov cam rau cov ntaub ntawv kom koom nrog, lawv yuav tsum raug ntxuav ntawm ntau yam oxides. Qhov no ua tiav siv cov flux - ib qho khoom siv organic lossis hluavtaws xob uas, thaum muab rhaub, tsis tsuas yog tshem tawm cov hlau oxide saum npoo ntawm cov hlau, tab sis kuj tseem ua rau cov yoov kis tau zoo dua thiab txhawm rau nruj dua ntxiv rau cov khoom siv kom tau soldered. Qhov feem ntau flux siv rau ntau xyoo yog rosin-based, tab sis tsis ntev los no tau muaj ntau qhov zoo tshaj plaws ua kua fluxes uas tsis tshua muaj siab rau cov hlau soldering.
Soldering qhov kav hluav taws xob kuj tseem txawv heev, txawm li cas los xij, rau qhov pib, qhov hluav taws xob soldering hlau uas tsis tshua muaj zog me me yog qhov tsim nyog rau koj. Yog tias cov nyiaj tso cai, koj tuaj yeem yuav qhov chaw nres tsheb soldering: lub teeb uas muaj cov hlau soldering nws tus kheej, ntau qhov sawv ntsug, thiab tseem ceeb tshaj, tus tswj hwm hluav taws xob uas yuav tso cai rau koj kom tsis txhob dhau lub qhov cub hlau soldering. Qhov ntxeev ntawm cov hlau tshiab soldering yuav tsum ua tib zoo "tsis muaj dab tsi", uas yog, txheej tiv thaiv ntawm kub muag yuav tsum muaj ntaub ntawv.
Soldering tshuab
Txoj kev soldering tiag tiag yog yooj yim heev. Ua ntej tshaj plaws, koj yuav tsum ua kom sov cov hlau soldering. Cov cua kub kub tau txiav txim siab txaus yog tias cov hlau soldering melts ham. Xyuam xim tsis txhob overheat taub. Ntawm kev overheated soldering hlau, ham tsis tuav, tab sis sau hauv tee. Tom qab ntawd, koj yuav tsum tau ntxuav qhov chaw ntawm yav tom ntej soldering nrog cov ntawv sau los yog sandpaper. Tom qab ntawd nyias nyias ntawm cov flux yuav tsum tau siv rau qhov chaw huv si thiab muaj txheej txheem. Koj tuaj yeem yog ib qho yooj yim ntsaws rau qhov chaw kom tau soldered molten solder, los yog kov lawv nrog cov hau ntawm cov hlau soldering. Nyob rau hauv txhua rooj plaub, qhov tshwm sim yuav tsum yog txheej txuas ntxiv ntawm solder.
Nws tshua tsuas yog txuas cov seem thiab txhim kho lawv txoj haujlwm zoo hauv qhov chaw xav tau. Yog tias koj cam cov xov hluav taws xob, koj tuaj yeem hloov kho lawv ua ke kom muaj kev ntseeg tau, txawm hais tias hauv kev coj ua no feem ntau tsis tsim nyog. Tom qab txhim kho qhov chaw tinned, pib ua kom sov lawv nrog hlau soldering. Koj yuav tsum xyuas kom meej tias qhov kub ntawm cov feem ntau tshaj li qhov chaw melting ntawm ham. Qee qhov xwm txheej, yuav tsum muaj ntxiv cov nqi ntawm cov yob ntxiv, uas yog thov nrog lub hau txuas nrog hlau. Nco ntsoov tias txhua tus cam yog yaj thiab cov seem muaj kev ruaj ntseg sib txuas thoob plaws txhua qhov chaw tiv tauj, tsis li ntawd txoj kev sib cuag yuav tsis yooj yim. Cia cov ntu kom txias kiag li ua ntej xoob lawv, raws li ib qho kev txav thaum lub sijhawm ua kom cov leeg tsis huv tuaj yeem ua kom lub zog ntawm kev sib koom ua ke.
Yuav pib nrog, koj yuav tsum tau xyaum ntawm cov hlau tsis tseem ceeb ntawm cov kav hlau, cov ntawv luam tawm qub thiab cov xov tooj sib txuas txha txhawm rau kawm kom paub ntsuas cov ntsuas kub, qhov yuav tsum tau ntawm flux thiab cam. Ob peb teev ntawm kev xyaum yog feem ntau txaus kom tau txais dai ntawm hlau soldering.
