Vuam kev txawj ntse ntawm hluav taws xob soldering hlau nyob rau hauv kev kho thiab ntau lawm txheej txheem
Kev ua haujlwm vuam yog qhov tseem ceeb hauv kev saib xyuas thiab kev tsim khoom. Nws tsis yog tsuas yog yuav tsum tau kho cov khoom ntawm lub rooj tsavxwm, tab sis kuj yuav tsum tau cov pob qij txha kom ruaj khov thiab du. Yog li ntawd, qhov zoo ntawm vuam tshuab ncaj qha cuam tshuam rau kev ua tiav ntawm kev tsim hluav taws xob. Yog li ntawd, vuam tshuab yog ib qho kev txawj ntse uas txhua tus neeg siv khoom siv hluav taws xob yuav tsum paub. Tam sim no, cia peb qhia cov ntsiab lus tseem ceeb ntawm welding:
1. Kev xaiv hluav taws xob soldering hlau Lub zog ntawm cov hluav taws xob soldering hlau yuav tsum tau txiav txim siab los ntawm qhov loj ntawm qhov sib koom ua ke. Lub cheeb tsam ntawm lub solder sib koom yog loj, thiab lub tshav kub dissipation ceev ntawm lub solder sib koom kuj ceev. Yog li ntawd, lub zog ntawm cov xaiv hluav taws xob soldering hlau yuav tsum siab dua. Lub zog ntawm lub tshuab hluav taws xob dav dav suav nrog 20W25W30W35W50W, thiab lwm yam. Xaiv lub zog ntawm ib ncig ntawm 30W yog qhov tsim nyog dua. Tom qab siv ntev, ib txheej ntawm oxide yuav tsim rau ntawm qhov kawg ntawm lub tshuab hluav taws xob, ua rau nws nyuaj rau nws noj tin. Nyob rau hauv rooj plaub no, koj tuaj yeem siv cov ntaub ntawv tshem tawm cov txheej oxide, tig cov hlau nplaum, thiab thaum lub taub hau kub me ntsis, ntxig rosin thiab siv cov hlua txuas ntxiv mus. Cov khoom siv hluav taws xob uas tau muag tshiab yuav tsum tau tinned ua ntej siv.
2. Tsawg melting point solder hlau thiab tsis corrosive flux, xws li rosin, yuav tsum tau siv rau soldering thiab flux. Kev lag luam solder thiab corrosive acidic solder roj yuav tsum tsis txhob siv. Nws yog qhov zoo tshaj plaws los siv cov hlau nplaum uas muaj rosin, uas yooj yim heev rau siv.
3. Vuam txoj kev: Cov khoom yuav tsum tau ntxuav thiab tinned. Thaum lub sijhawm khaws cia, cov khoom siv hluav taws xob tuaj yeem muaj txheej txheej ntawm oxide zaj duab xis txuas rau cov pins vim huab cua oxidation, nrog rau lwm yam av. Ua ntej welding, ib rab riam me tuaj yeem siv los txhuam cov oxide zaj duab xis thiab tam sim ntawd siv ib txheej ntawm solder (feem ntau hu ua enamel) ua ntej vuam. Tom qab cov kev kho mob saum toj no, cov khoom yog ib qho yooj yim rau solder khov kho thiab tsis nquag mus dag soldering.
Qhov kub thiab lub sij hawm ntawm vuam yuav tsum yog xws li qhov kub ntawm cov hluav taws xob soldering hlau yog siab tshaj qhov kub ntawm lub soldering tin, tab sis nws yuav tsum tsis txhob siab dhau. Nws yog qhov zoo dua rau lub taub hau ntawm lub taub hau kom nkag mus rau hauv kev sib cuag nrog rosin thiab haus luam yeeb tam sim no. Yog hais tias lub sij hawm vuam luv luv, qhov kub ntawm qhov sib koom ua ke yog tsawg dhau, lub melting ntawm solder sib koom tsis txaus, thiab cov solder sib koom yog ntxhib, nws yog ib qho yooj yim los ua virtual soldering. Conversely, yog hais tias lub sij hawm vuam ntev dhau lawm, lub solder yog nquag ntws, thiab nws yooj yim los ua overheating thiab puas rau cov khoom.
Tus nqi ntawm solder ntawm lub solder sib koom yuav tsum tsis txhob me heev. Yog hais tias nws yog me me, lub soldering yuav tsis ruaj thiab mechanical zog yuav tsis zoo. Thiab ntau dhau tuaj yeem yooj yim ua rau ntau qhov tsos thiab kev cuam tshuam sab hauv.
Soldering yuav tsum cia li submerge tag nrho cov pins ntawm lub Cheebtsam ntawm lub solder sib koom, thiab cov qauv yuav tsum tau vaguely pom.
Them mloog mus rau txoj hauj lwm ntawm cov hlau soldering thiab vuam cov ntsiab lus. Cov pib feem ntau txav cov hluav taws xob soldering hlau rov qab los yog nyem nws quab yuam ntawm qhov chaw vuam. Txoj kev no tsis raug. Txoj kev raug yog siv lub tinned nto ntawm ib qho hluav taws xob soldering hlau hu rau lub vuam taw tes, uas muaj ib tug loj tshav kub hloov chaw thiab ib tug ceev vuam ceev.
4. Kev tshuaj xyuas tom qab vuam: Tom qab vuam, nws yuav tsum tau kuaj xyuas seb puas muaj cov khoom tawg, cov pob qij txha, los yog luv luv Circuit Court nyob rau hauv cov khoom uas tshwm sim los ntawm solder flow. Virtual soldering yog qhov nyuaj rau kev ntes, yog li koj tuaj yeem siv cov tweezers los clamp cov pins tivthaiv thiab maj mam rub lawv. Yog tias pom muaj kev co, nws yuav tsum tau kho tam sim ntawd
