Qhov sib txawv ntawm ib tug taw tes soldering hlau thiab ib tug soldering hlau nyob rau hauv cov duab ntawm ib tug cwj mem
1. cwj mem-zoo li tus soldering hlau
Hom hluav taws xob soldering hlau feem ntau yog taw qhia, thiab muaj ob hom: kho qhov kub thiab txias tsis hloov.
Nws cov yam ntxwv yog: pheej yig tus nqi, haum rau soldering plug-in Cheebtsam, non-adjustable cwj mem-zoo li tus hluav taws xob soldering hlau, oxidized nrog lub sij hawm ntev kub, thiab lub ntsis ntawm lub ntsis yog tsis tinned.
Rau hom LQFP pob thiab TSSOP pob, cov taw qhia cov hlau yog feem ntau tsis yooj yim rau siv, thiab nws tsis tuaj yeem hloov nrog rab riam-ntug soldering hlau taub, uas muaj kev txwv loj.
Nws tsuas yog soldering ntawm plug-in Cheebtsam. Thaum ua qee qhov kev xav tau yooj yim soldering, koj tuaj yeem siv hluav taws xob tsis zoo.
2. Taw tes soldering hlau
Cov chaw kho mob feem ntau yog qhov ntsuas kub-kho tau, thiab qee qhov muaj cov phom kub. Tus thawj yog taw tes, tab sis vim yog cov qauv kev sib raug zoo, nws tuaj yeem hloov tau nrog rab riam-edged.
Thaum siv cov hlau taw qhia, qhov ntsuas kub tuaj yeem hloov kho li ntawm 350 rau cov khoom siv hluav taws xob dav dav. Thaum muaj cov kiv cua kub tsim ntawm PCBA, qhov kub tuaj yeem nce ntxiv kom tsim nyog los xyuas kom meej tias qhov kub tuaj yeem yaj cov tin ntawm PCBA.
Vim tias riam ntug ntawm lub taub hau hlau tuaj yeem ua tau zoo rau cov pins ntawm SOP / TSSOP / LQFP pob, nws yuav yooj yim dua thaum lub sij hawm desoldering.
Kev xaiv ntawm hluav taws xob soldering hlau, xaiv kev txawj ntse ntawm solder thiab flux
1. Kev xaiv hluav taws xob soldering hlau
Lub zog ntawm cov hlau soldering yog txiav txim siab los ntawm qhov loj ntawm qhov taw tes soldering. Lub cheeb tsam ntawm qhov taw tes soldering yog qhov loj, thiab cov cua kub dissipation ceev ntawm qhov taw tes soldering kuj ceev. Lub zog ntawm cov hlau soldering yuav tsum loj dua.
Feem ntau, lub zog ntawm cov hluav taws xob hluav taws xob yog 20W, 25W, 30W, 35W, 50W, thiab lwm yam, thiab lub zog ntawm 30W feem ntau yog xaiv.
Soldering hlau tin:
Lub tshuab hluav taws xob uas nyuam qhuav yuav tshiab yuav tsum tau tinned ua ntej nws tuaj yeem siv tau.
Tom qab siv cov hlau nplaum ntev ntev, ib txheej ntawm oxide yuav raug tsim rau ntawm qhov kawg ntawm cov hlau soldering, thiab nws yuav tsis yooj yim rau noj tin. Koj tuaj yeem siv cov ntaub ntawv los ua cov txheej txheem oxide. Tom qab lub tshuab hluav taws xob siv hluav taws xob, ntxig rosin thaum lub taub hau ntawm cov hlau soldering kub me ntsis, thiab siv cov solder Koj tuaj yeem siv txuas ntxiv mus.
2. Solder thiab flux
Thaum xaiv solder thiab flux, feem ntau xaiv solder hlau uas tsis tshua muaj melting point, xaiv non-corrosive flux, xws li rosin, tsis txhob siv industrial solder thiab corrosive acidic solder roj, feem ntau siv solder hlau uas muaj rosin.
