Yuav ua li cas los daws qhov teeb meem uas lub ntsis ntawm cov hlau soldering tsis lo rau lub solder
1. Npaj cov hlau nplaum zoo, rosin, thiab daim txhuam cev kub. Tig lub hluav taws xob soldering hlau, thaum qhov kub thiab txias, ntxig lub taub hau rau hauv cov rosin, thiab co rov qab thiab tawm mus. Tom qab ntawd tshem tawm cov npaj solder thiab yaj nws nyob rau hauv kev sib cuag nrog lub ntsis ntawm lub soldering hlau.
2. Yog hais tias lub taub hau hlau tau oxidized thiab blackened, koj tuaj yeem npaj cov ntaub ntawv (yog tias tsis muaj ntaub ntawv, koj tuaj yeem npaj cov ntawv xuab zeb). Siv cov ntaub ntawv los yog cov ntawv xuab zeb los txhuam cov hlau nplaum kom tshem tawm cov txheej oxide dub rau ntawm qhov chaw ntawm cov hlau taub hau.
3. Lub hau ntawm cov hlau soldering feem ntau yog ua los ntawm cov hlau tooj liab. Tom qab oxidation, dub tooj liab oxide (CuO) yuav tsim rau saum npoo. Copper oxide yog non-stick solder. Koj tuaj yeem ntxig qhov taub ntawm cov hlau nplaum rau hauv 90 feem pua tshuaj cawv rau kev kho mob. Nws yuav tsum tau muab sau tseg tias nws yuav tsum tau muab tso rau hauv lub xeev unheated, ces energized, thiab tshem tawm tom qab 1-2 feeb, qhov teeb meem ntawm oxidized non-stick solder yuav daws tau.
Tom qab tham txog kev daws teeb meem rau oxidized non-stick solder, txhawm rau kom tsis txhob muaj oxidation zoo li no yav tom ntej, peb yuav tsum siv cov hluav taws xob soldering hlau kom raug li cas?
1. Thawj lub ntsiab lus los tham txog yog kev siv cov flux no (soldering paste). Feem ntau ntawm cov fluxes yog acidic fluxes, uas muaj qee yam oxidation nyhuv ntawm qhov kawg ntawm cov hlau soldering. Sim tsis txhob siv lawv.
Ntawm no kuv pom zoo ib txoj hauv kev zoo tshaj rau kev ua cov flux, uas yog kom rosin rau hauv cov hmoov thiab ncuav rau hauv dej cawv daws kom tag nrho cov kua. Qhov sib piv no feem ntau yog 40 feem pua rosin hmoov ntxiv rau 60 feem pua tshuaj cawv, thiab tsis muaj teeb meem nrog me ntsis ntxiv rosin. Nws yuav tsum raug sau tseg tias haus cawv tsis tuaj yeem siv tshuaj kho mob, thiab cov kua dej cawv ntau dua 90 feem pua yuav tsum tau siv, thiab lub thawv yuav tsum muab kaw.
2. Qhov thib ob yog qhov teeb meem hluav taws xob. Ntau tus phooj ywg tsis siv los tshem tawm lub hwj chim ntsaws lub sij hawm tom qab siv. Thaum lub taub hau hlau yog nyob rau hauv ib lub xeev rhuab, nws yuav oxidize tsis-stick solder. Yog li ntawd, kev siv txhua hnub yuav tsum tau ua, thiab cov khoom siv hluav taws xob yuav tsum raug txiav tawm hauv lub sijhawm tom qab siv.
3. Lub ntsiab lus thib peb yog qhov tinning ntawm lub taub hau hlau uas ntau tus neeg tsis quav ntsej. Yuav kom txuag tau qhov teeb meem, feem ntau ntawm cov hlau soldering yuav tsis tinn lub taub hau soldering tom qab siv nws. Txawm hais tias tom qab lub taub hau ntawm cov hlau tsis muaj zog, nws qhov kub thiab txias yog siab heev thiab nws yuav oxidize nrog huab cua, thiab tinning nws ua ntej lub hwj chim tawm tuaj yeem tiv thaiv nws los ntawm oxidized.
4. Lub ntsiab lus thib plaub yog hais txog soldering tin. Muaj cov zoo soldering tins thiab phem soldering tins. Yuav kom txuag tau nyiaj, feem ntau cov neeg yuav pheej yig solder hlau. Txawm hais tias nws yog pheej yig, qhov zoo yog kev txhawj xeeb heev. Solder slag yog ib qho yooj yim los tshwm, thiab txawm ua solder slag thaum rhuab.
5. Lub ntsiab lus thib tsib thiab qhov kawg uas kuv xav hais txog yog lub ntsiab lus ntawm cov hlau soldering. Ib tug zoo soldering hlau taub yuav ua tau ob zaug qhov tshwm sim nrog ib nrab ntawm kev rau siab. Rau peb niaj hnub siv, peb tuaj yeem siv lub taub hau los yog rab riam, tab sis peb yuav tsum tau yuav ib lub taub hau zoo dua. Piv txwv li, lub taub hau hlau ua los ntawm tooj liab yog qhov ruaj khov thiab muaj zog oxidation tsis kam.
