Ntau txoj hauv kev thiab cov txheej txheem ntawm kev sib txuas yog ib txwm siv txhawm rau txhawm rau sib sau cov hluav taws xob hluav taws xob, tsim cov ntawv luam tawm tiav nrog cov xov tooj cua, kom txhua qhov chaw tuav ruaj khov. Soldering tsis yog tsuas yog sib txawv ntawm cov xov hlau, cables, tab sis kuj tseem lub teeb qhov muag teev, resistors, transistors, diodes, microcircuits, yuam sij, nyees khawm, choj circuits, thiab lwm yam. Tsis yog txhua leej txhua tus paub yuav ua li cas solder hlau rau hlau, txawm hais tias qhov kev txawj no yog qee zaum tsim nyog.
Soldering tuaj yeem ua tau yooj yim txawm tias nyob hauv tsev: yog tias koj yuam kev xaim hauv koj lub xov tooj cua uas koj nyiam vim muaj lub zog hluav taws xob, lossis koj txiav txim siab los tsim lub suab nrov ntawm koj tus kheej tes kom lub suab nrov nrov ntawm koj tog.
Xaiv hlau thiab lwm yam cuab yeej
Ua ntej yuav ncaj qha mus rau soldering, koj yuav tsum xaiv cov hlau soldering thiab txhua yam uas koj xav tau ua haujlwm.
Ua ntej tshaj plaws, xaiv cov hlau nplaum, lawv txawv ntawm lub zog. Yog li ntawd, koj yuav tsum xav txog dab tsi raws nraim yuav tsum tau soldered. Yog hais tias cov no yog cov xov tooj cua uas ntshai heev overheating, los yog microcircuits, lub zog zoo ntawm cov hlau soldering yuav yog 5-20 watts. Yuav kom solder ib tug hlau mus rau ib tug hlau los yog lub davhlau ya nyob twg, ib tug soldering hlau nrog lub hwj chim ntawm 40-50watt. Txhawm rau txuas cov hlau uas muaj qhov tuab ntawm 3 hli lossis ntau dua, koj yuav tsum xaiv cov hlau nplaum uas muaj lub zog ntawm 50 watts lossis ntau dua.
Tsis tas li, txhawm rau ua haujlwm nrog cov hlau nplaum, koj yuav tsum npaj:
- solder;
- ntev tweezers;
- pliers;
- rosin, flux lossis soldering acid.
Yuav ua li cas npaj rau soldering
Ua ntej ua haujlwm, lub taub hau hlau yog ntxuav ntawm cov pa roj carbon monoxide los ntawm kev ntxuav nws nrog cov ntaub ntawv. Tom qab ntawd cov hlau txuas txuas nrog lub ntsiab, rhuab thiab dipped hauv rosin.
Yog koj tsis tau ua hauj lwm nrog cov hlau soldering thiab tsis paub yuav ua li cas solder hlau rau hlau, koj yuav tsum tau xyaum.
Ua li no, muab ib daim ntawm cov khib nyiab tsis muaj rwb thaiv tsev thiab muab faib ua 12 qhov sib npaug ntawm 2.5 cm txhua. Siv cov tweezers, cov hlau soldering, solder thiab flux, sim sib sau ua ke ib lub voos xwmfab ntawm cov khoom no. Qhov no yuav yog ib qho kev xyaum zoo rau kev kawm yuav ua li cas solder. Tom qab qhov tsim tau npaj txhij, cia nws txias thiab xyuas seb txhua qhov kev sib txuas yog nruj npaum li cas. Yog tias muaj dab tsi poob, solder nws.
Ua ntej ua haujlwm, txhua qhov chaw uas yuav tsum tau ua yuav tsum tau tinned.
Txoj cai tseem ceeb ntawm kev sib tw
Cov xov hlau uas muaj cov hlau nplaum yuav tsum tau ua raws li qee qhov kev cai kom ua haujlwm tau zoo thiab txhim khu kev qha. Soldering yog yuav tsum tau rau soldering, feem ntau siv yog POS-40, POS-50, POS-61. Cov tom kawg tau ua tiav thiab feem ntau siv hauv kev tsim khoom. Yuav kom solder, koj yuav tsum sov li qhov chaw uas nws yuav siv tausolder, mus rau qhov kub kom lub solder yaj thiab cov xov hlau tsis overheat.
Txhua txoj haujlwm ntawm cov hlau nplaum muaj cov theem ua tiav:
- Cov hlau raug npaj rau kev sib tsoo. Cov oxide zaj duab xis yuav tsum tau muab tshem tawm los ntawm so nrog soldering acid los yog rosin.
- Ib lub tshuab ua ntej-rhuab soldering yog coj mus rau lub solder, nws yog siv tsawg heev kom tsis txhob muaj ntau influxes nyob rau hauv qhov chaw ntawm soldering.
- Cov hlau nplaum yog siv rau cov hlau thiab cov hlau nplaum raug coj mus rau qhov chaw ntawm lawv cov kev sib cuag raws nraim rau lub sijhawm nws yuav siv sij hawm kom cov hlau nyob ntawm qhov sib txuas ntawm cov xov hlau.
Tsis tas yuav tuav cov hlau nplaum ntau dhau ze ntawm cov xov hlau. Nws yuav siv li ob peb vib nas this rau lub solder tuav cov xov hlau ua ke. Tom qab lub taub raug tshem tawm ntawm qhov chaw ntawm soldering, lub solder solidifies. Yog li hais tias qhov kev sib tshuam tsis tas yuav tsum tau soldered, thiab nws hloov tawm kom zoo, cov xov hlau yuav tsum tau tuav tsis muaj zog kom txog thaum lub solder tau tag nrho hardened. Yog hais tias muaj ntau dhau ntawm flux ntawm qhov chaw ntawm soldering, nws yuav tsum tau muab tshem tawm. Qhov no yog tsim nyog kom qhov chaw ntawm soldering tsis oxidize lub sij hawm.
cov lus qhia pab tau
Ua ntej koj tuaj yeem xyaum ua ntej yuav ua li cas solder hlau rau hlau, ntawm no yog qee cov lus qhia uas koj xav tau.
Thaum lub sijhawm soldering, koj tsis tas yuav siv ntau lub solder, nws txaus me ntsis kom cov solder tuaj yeem nkag mus rau hauv micro-kawg ntawm cov khoom thiab txuas cov xov hlau. Qhov no yuav txaus rau lub zog ntawm kev sib cuam tshuam ntawm intermolecular pib ua.
Txhawm rau tshem tawm cov solder ntau dhau,Koj tuaj yeem siv cov hlua khi tiv thaiv los ntawm txhua lub cable. Thiab kuj tseem siv cov hlau nplaum, uas muaj qhov khoob ntawm qhov taub, rau hauv qhov uas ntau tshaj solder tau txais thaum nws kov qhov taw tes.
Ntau dhau solder tuaj yeem ua rau cov neeg sib cuag luv.
Yog tias koj muab cov hlau me me rau ntawm qhov kawg ntawm cov hlau soldering, koj yuav tsis muaj peev xwm solder dab tsi.
Yog tias muaj ntau cov kua qaub los yog cov dej ntws tawm ntawm cov hlau soldering, cov hlau yuav dhau los ua qhov tsis zoo. Tib yam yuav tshwm sim yog tias cov hlau tsis tau rhuab mus rau qhov xav tau kub.
Tsis txhob hnov qab muab cov pa zoo los yog hauv qhov chaw muaj cua zoo.
Tam sim no koj paub yuav ua li cas solder hlau rau xaim kom zoo.
