Kev siv cov hlau soldering kom raug hauv kev kho hluav taws xob
Cov hlau soldering yog ib qho tseem ceeb rau kev kho hluav taws xob. Txoj kev siv kom raug, kev ceev faj thiab cov lus qhia rau kev siv cov hlau soldering hauv kev ntsuas ntsuas hluav taws xob. Txhawm rau txhim kho koj cov kev txawj ntse, koj yuav tsum xub paub siv cov hlau soldering.
1. Yuav ua li cas tuav cov hlau soldering
① Yuav tuav tus cwj mem li cas
Tus cwj mem tuav txoj kev yog tsim rau hluav taws xob soldering irons uas tsis tshua muaj zog thiab ncaj ncaj, thiab yog tsim rau vuam qhov chaw yuav tsum tau welded nrog me me tshav kub dissipation, xws li luam tawm Circuit Court boards nyob rau hauv vuam seev. Tus cwj mem tuav txoj kev yog txoj kev siv ntau tshaj plaws los ntawm cov neeg ua haujlwm ntsuas.
②Nyob rau pem hauv ntej tuav
Txoj kev tuav upright yog tsim rau soldering hlau nrog cov lus qhia loj thiab nkhaus. Nws tuaj yeem siv rau vuam thaum lub rooj tsav xwm Circuit Court yog ntsug rau lub desktop.
③ Rov qab tuav
Txoj kev tuav rov qab yog tuav tus tuav ntawm cov hlau soldering nyob rau hauv xib-teg ntawm koj txhais tes nrog koj tsib ntiv tes. Txoj kev no yog tsim rau cov hluav taws xob hluav taws xob siab, cov hlau nplaum, thiab cov vuam qhov chaw uas dissipate loj tshav kub.
2. Xaiv cov hlau nplaum raws li nws lub hom phiaj
Thaum vuam cov khoom sib xyaw ua ke ntawm cov ntawv luam tawm, xws li diodes, transistors, resistor-capacitor Cheebtsam, thiab kev sib xyaw ua ke, yuav tsum tau siv ib qho 20-30W sab hauv cov cua sov soldering hlau. Vim lub vuam qeeb qeeb, nws raug pom zoo rau cov novices siv 20W. Thaum vuam cov khoom siv nrog cov pins tuab lossis cov ntsiab lus loj hauv cheeb tsam ntawm cov ntawv luam tawm lossis cov khoom siv fais fab, nws raug nquahu kom siv 45-75W soldering hlau los xyuas kom meej qhov ruaj khov ntawm cov khoom siv welded thiab cov ntawv luam tawm lossis cov xov hlau. Tsis txhob siv lub tshuab hluav taws xob uas tsis tshua muaj hluav taws xob siv los txuas cov pob qij txha ntawm cov khoom siv hluav taws xob loj. Vim yog lub tshav kub sai sai thiab kub ceev poob ntawm lub taub hau soldering, solder tsub zuj zuj yuav tshwm sim, uas tej zaum yuav tshwm sim los soldered tab sis yog ib tug tsis muaj zog solder. Kev siv lub tshuab hluav taws xob muaj zog los ua cov khoom siv hluav taws xob dav dav ntawm lub rooj tsav xwm luam tawm feem ntau yuav hlawv cov kab ntawv tooj liab lossis cov khoom siv hluav taws xob.
3. Xam cov kauj ruam vuam kom raug
Qib ntawm vuam txiav txim siab qhov kev ruaj ntseg thiab kev ntseeg siab ntawm cov cuab yeej raug kho. Cov teeb meem zoo nrog cov pob qij txha me me tuaj yeem ua rau tag nrho cov cuab yeej lossis kev tswj hwm tsis ua haujlwm zoo, thiab qhov ua txhaum feem ntau yog qhov zais cia. Yog li ntawd, mastering qhov tseeb vuam cov kauj ruam yog tus yuam sij kom ntseeg tau tias vuam zoo. Ntawm no yog ib qho kev taw qhia.
① Muab cov hlau nplaum rau ntawm tus pin ntawm cov khoom uas yuav tsum tau soldered, thiab ua kom sov lub solder sib koom ua ntej. Thaum lub solder sib koom mus txog qhov tsim nyog qhov kub thiab txias, tso cov rosin solder hlau rau ntawm lub solder sib koom nyob rau hauv lub sij hawm kom yaj nws.
② Tom qab cov tin melts, lub taub hau hlau yuav tsum tau txav me ntsis raws li cov duab ntawm cov khoom sib koom ua ke kom cov khoom sib npaug sib npaug ntawm cov sib koom ua ke thiab nkag mus rau hauv qhov khoob ntawm qhov chaw soldered. Tom qab qhov tsim nyog tus nqi ntawm solder tau yaj, lub solder hlau yuav tsum tau muab tshem tawm sai sai.
③Thaum lub solder sib koom ua ke yuav luag tag nrho ntawm solder, cov flux tsis tas evaporated, qhov kub thiab txias yog qhov tsim nyog, thiab lub solder yog lub ci ntsa iab thiab cov kua dej ntau tshaj plaws, txav cov hlau taub hau sai sai raws li cov kev taw qhia ntawm cov khoom siv pins. Thaum koj tab tom yuav tawm mus, nqa rov qab sai sai, thiab tib lub sijhawm Cia cov khoom sib koom ua ke los xyuas kom meej tias qhov chaw ntawm cov khoom sib txuas yog ci, du thiab tsis muaj burr. Thaum kawg, siv cov kab pheeb ces kaum los txiav cov pins ntev ntev kom txog thaum cov pins tiv thaiv me ntsis raug rau cov pob qij txha.
Lub sijhawm ua haujlwm ntawm cov kauj ruam saum toj no ①-② yuav tsum tswj tsis pub dhau 2-3 vib nas this. Beginners feem ntau siv sij hawm ntev los vuam. Lub sij hawm cua sov ntev yuav ua rau cov ntawv ci tooj liab ntawm lub rooj tsav xwm luam tawm kom puas dhau kev kho. Kauj Ruam ③ ua lub luag haujlwm txiav txim siab ntawm qhov zoo ntawm cov pob qij txha, thiab koj yuav tsum tau xyaum ntau ntxiv kom nkag siab txog nws qhov tseem ceeb.
4. Yuav ua li cas tiv thaiv lub taub hau soldering
Ua ntej yuav siv cov khoom siv hluav taws xob tshiab, cov hlau nplaum yuav tsum tau tinned. Rau cov lus qhia tooj liab soldering hlau, koj tuaj yeem siv cov ntawv xuab zeb los yog cov ntaub ntawv los txhuam cov hlau nplaum ua ntej. Cov xim ntawm cov hlau nplaum yuav hloov tom qab ob peb feeb ntawm kev txuas nrog lub hwj chim, qhia tias cov hlau soldering kub. Tos kom txog thaum lub taub hau soldering yog rhuab. Thaum qhov kub nce mus rau lub melting point ntawm lub solder, siv nws los dip lub rosin solder hlau. Qhov saum npoo ntawm cov hlau taub hau yuav dipped nyob rau hauv ib txheej ntawm ci tin, thiab soldering hlau taub yuav siv tau. Yog hais tias lub taub hau ntawm cov hlau tsis yog dipped nyob rau hauv tin, nws yuav tsis tinned thaum lub sij hawm soldering, thiab nws yog tsis yooj yim sua rau solder.
Lub taub hau soldering hlau yuav tsum tau ceev kom huv si. Lub taub hau ntawm cov hlau tsis huv yuav sai sai oxidize thiab ua tsis tau kom nqus cov tin. Nyob rau tib lub sij hawm, nws yuav ua rau corroded pits ntawm lub soldering hlau taub, ua rau vuam ua hauj lwm nyuaj. Yog hais tias cov hlau soldering tau tso rau hauv lub xeev soldering rau lub sijhawm ntev thiab qhov kub thiab txias, nws tseem yuav ua rau lub taub hau ntawm lub taub hau "hlawv". Thaum tsis vuam, tua lub hwj chim ntawm cov hlau soldering tam sim ntawd. Cov oxides thiab carbides muab tau los ntawm cov residual flux nyob rau hauv lub soldering hlau taub yuav ua rau lub soldering hlau taub thiab txo nws thermal conductivity. Yog li ntawd, koj yuav tsum nco ntsoov ntxuav lub taub hau nrog lub qhov kub-resistant ntub daim txhuam cev kom tsis txhob muaj kev puas tsuaj rau cov hlau taub hau. Tom qab txhua qhov kev siv, lub taub hau hlau yuav tsum tau muab ntxuav kom huv thiab dipped nyob rau hauv ib txheej ntawm tin los tiv thaiv lub taub hau.
