Soldering txhuas tuaj yeem ua rau nyuaj yog tias koj tsis tau ua nws ua ntej. Aluminium oxide yuav ua rau koj qhov kev sim feem ntau tsis muaj txiaj ntsig. Tab sis, thaum koj muaj lub tswv yim meej ntawm cov txheej txheem, nws dhau los ua qhov yooj yim heev. Qhov ntawd yog qhov kuv tuaj hauv. Tab sis ua ntej peb nkag mus rau qhov ntawd, cia mus dhau qee qhov pib.

Dab Tsi Yog Dab Tsi?

Soldering yog ib txoj hauv kev koom nrog ob daim hlau ua ke. Cov hlau yaj ua kom yaj cov hlau uas ua rau ob daim hlau ua haujlwm lossis qee thaj chaw cim. Cov laug, koom nrog cov hlau yaj, txias sai heev tom qab tshem cov cua sov thiab ua kom ruaj khov kom cov hlau nyob hauv qhov chaw. Zoo nkauj heev muaj zog kua nplaum rau hlau.

Sib piv cov hlau zoo dua qub tau siv los tuav lawv ua ke. Cov hlau hnyav feem ntau yog welded. Koj ua tau ua koj tus kheej soldering hlau tsuas yog rau koj cov haujlwm tshwj xeeb ib yam nkaus.

Solder

Nws yog ib qho kev sib xyaw ntawm ntau yam hlau thiab siv rau kev sib dhos. Nyob rau thaum ntxov, cov laug tau ua nrog cov hlau thiab cov hlau lead. Tam sim no, cov kev xaiv uas tsis muaj cov hmoov txhuas tau siv ntau dua. Soldering cov xov hlau feem ntau muaj cov tin, tooj liab, nyiaj, bismuth, zinc, thiab silicon.

Cov laug muaj qhov taw tes qis thiab ua kom nrawm. Ib qho ntawm qhov yuav tsum tau ua rau cov laug yog lub peev xwm los ua hluav taws xob raws li cov khoom siv tau siv ntau hauv kev tsim hluav taws xob.

ntws

Flux yog qhov tseem ceeb rau kev tsim cov khoom sib txuas zoo. Cov laug yuav tsis ntub qhov sib koom ua ke yog tias muaj cov hlau oxide txheej. Qhov tseem ceeb ntawm flux yog vim nws muaj peev xwm tiv thaiv cov hlau oxides los ntawm kev sib sau. Hom fluxes siv hauv cov tshuab hluav taws xob uas feem ntau siv feem ntau yog ua los ntawm rosin. Koj tuaj yeem tau txais cov rosin nyoos los ntawm cov ntoo thuv.

Txhuas Txhuas Txhuas

Nws yeej tsis zoo ib yam li kev ntseeg orthodox. Ua tus thib 2 feem ntau cov hlau tsis zoo nyob hauv lub ntiaj teb thiab muaj qhov ua tau zoo ntawm cov cua sov ua kom sov, Txhuas cov khoom ua haujlwm feem ntau zoo dua qub. Yog li, txawm hais tias lawv tuaj nrog qhov ua tau zoo, ua kom sov ntau ntxiv tseem yuav ntxig thiab/lossis hloov pauv nws.

Cuab Yeej Cuab Yeej

Ua ntej pib, nws tseem ceeb heev kom ntseeg tau tias koj muaj cov cuab yeej tsim nyog los txhawm rau txhuam cov txhuas. Raws li txhuas muaj qhov qis me ntsis ntawm ib puag ncig 660 ° C, koj yuav xav tau cov laug uas muaj lub ntsiab lus qis dua ib yam. Nco ntsoov tias koj cov hlau soldering tshwj xeeb yog hais rau koom nrog txhuas.

Lwm qhov tseem ceeb uas koj yuav tsum muaj yog cov dej ntws uas yog lub luag haujlwm rau soldering txhuas. Rosin fluxes tsuas yog yuav tsis ua haujlwm rau nws. Lub ntsiab lus melting ntawm cov dej ntws yuav tsum zoo ib yam li cov hlau txuas.

Hom Aluminium

Aluminium ntshiab tuaj yeem muab muag tab sis vim nws yog hlau tawv, nws tsis yooj yim los ua haujlwm nrog. Cov khoom lag luam txhuas feem ntau koj pom yog txhuas txhuas. Feem ntau ntawm lawv tuaj yeem muab muag rau tib txoj kev. Txawm li cas los xij, muaj qee qhov uas yuav xav tau kev pab tshaj lij.

Nyob rau hauv rooj plaub cov khoom lag luam txhuas koj tau cim nrog tsab ntawv lossis tus lej, koj yuav tsum saib mus rau qhov tshwj xeeb thiab ua raws nws. Aluminium alloys uas muaj 1 feem pua ​​magnesium lossis 5 feem pua ​​silicon yog qhov yooj yim dua rau cov laug.

Alloys uas muaj ntau qhov ntau ntawm cov no yuav muaj cov dej ntws tsis zoo. Yog tias cov hlau muaj qhov feem pua ​​siab ntawm tooj liab thiab zinc hauv nws, nws yuav muaj cov yam ntxwv tsis zoo vim yog los ntawm kev nkag mus sai sai thiab poob cov khoom ntawm cov hlau hauv paus.

Ua haujlwm nrog Aluminium Oxide

Soldering txhuas tuaj yeem nyuaj piv rau lwm yam hlau. Tias yog vim li cas koj nyob ntawm no tom qab tag nrho. Nyob rau hauv cov ntaub ntawv ntawm aluminium alloys, lawv nyob hauv txheej txheej ntawm aluminium oxide vim yog los ntawm kev sib chwv nrog huab cua.

Aluminium oxide tsis tuaj yeem siv tau, yog li koj yuav tsum txhuam nws ua ntej ua li ntawd. Tsis tas li, nco ntsoov tias cov hlau oxide no yuav hloov pauv sai heev thaum nws los rau hauv kev sib cuag nrog huab cua, yog li yuav tsum tau ua kom sai li sai tau.

Yuav Ua Li Cas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Txhuas Cov Hlau Cov kauj ruam

Tam sim no uas koj tau raug ntes ntawm cov hauv paus, koj yuav tsum tau npaj kom tau mus rau ntawm qhov muag. Ua raws cov theem no kom zoo kom paub tseeb tias koj ua nws kom raug.

Kauj Ruam-1: Cua Kub Koj Cov Hlau thiab Kev Nyab Xeeb Kev Nyab Xeeb

Nws yuav siv sijhawm luv kom tau koj cov hlau txuas mus rau qhov ntsuas kub zoo tshaj. Kuv xav qhia koj khaws daim ntaub ntub los yog daim txhuam cev los ntawm los ntxuav cov hlau tawm tej yam khoom qub. Hnav daim npog ntsej muag kev nyab xeeb, tsom iav, thiab hnab looj tes thaum koj nyob ntawm nws.

Kauj Ruam-2: Tshem Tawm Txheej Txhuas Txhuas Txhuas Txhuas Txhuas

Siv cov hlau txhuam kom tshem tawm cov txheej txheej ntawm cov hlau txhuas los ntawm txhuas. Yog tias koj siv aluminium qub nrog hnyav oxidization, koj yuav tsum xuab zeb lossis so siv acetone thiab isopropyl cawv.

Kauj Ruam 3: Ua Ntawv Thov Flux

Tom qab ntxuav cov khoom, siv cov dej ntws nrog rau cov chaw koj xav koom nrog. Koj tuaj yeem siv cov cuab yeej hlau lossis tsuas yog tus pas nrig ntawm cov laug rau kev thov. Qhov no yuav tso tseg aluminium oxide rau kev tsim thiab kos cov hlau txuas nrog rau sab ntev ntawm kev koom tes.

Kauj Ruam 4: Clamping/Positioning

Qhov no yog qhov tsim nyog yog tias koj koom nrog ob daim ntawm txhuas ua ke. Clamp lawv hauv txoj haujlwm koj xav koom nrog lawv. Nco ntsoov tias daim ntawm txhuas muaj qhov sib txawv me ntsis ntawm lawv thaum clamping rau cov hlau txuas kom ntws.

Kauj Ruam -5: Ua kom sov rau qhov ua haujlwm

Cua sov cov hlau yuav tiv thaiv kom tawg tau yooj yim "Txias koom nrog". Tshav kub qhov chaw ntawm daim uas nyob ib sab rau qhov sib koom nrog koj cov hlau txuas. Ua ntawv sov rau ib cheeb tsam yuav ua rau ntws thiab ua kom sov dhau, yog li, nco ntsoov txav koj cov cua sov kom qeeb. Txoj kev ntawd cheeb tsam tuaj yeem ua kom sov sib npaug.

Kauj Ruam 6: Muab Cov Kws Lij Choj tso rau hauv qhov sib koom ua ke thiab ua tiav

Ua kom sov koj lub lauj kaub kom txog thaum nws muag. Tom qab ntawd thov nws rau qhov sib koom tes. Yog tias nws tsis lo nrog txhuas, txheej txheej oxide tau hloov pauv. Koj yuav tsum tau txhuam thiab ntxuav cov khoom ib zaug ntxiv kuv ntshai. Nws yuav siv sijhawm li ob peb vib nas this rau cov laug kom qhuav. Tom qab ziab, tshem cov seem uas seem nrog acetone.

xaus

Nws yog txhua yam hais txog kev nkag siab cov txheej txheem thaum nws los txog rau txhuas txhuas. Tshem tawm cov txheej txheej aluminium oxide nyob rau sab saum toj nrog txhuam cov hlau lossis los ntawm cov xuab zeb. Siv cov tooj dag kom zoo, cov laug, thiab cov dej ntws. Tsis tas li, siv daim ntaub ntub rau tshem cov laug ntxiv rau qhov ua tiav zoo. Auj, thiab ib txwm siv kev tiv thaiv kev nyab xeeb.

Zoo, muaj koj muaj nws. Kuv vam tias tam sim no koj tau txais kev nkag siab yuav ua li cas txhawm rau txhuam cov txhuas. Tam sim no hauv qhov kev cob qhia, peb mus.
