Thaum hluav taws xob soldering hlau yog soldering, cov nram qab no 4 cov ntsiab lus yuav tsum tau ua:
1. Qhov chaw vuam yuav tsum tau ua kom huv si
Txawm tias cov weldments nrog zoo weldability, vim lub sij hawm ntev cia thiab muaj kuab paug, teeb meem oxide zaj duab xis, roj stains, thiab lwm yam yuav raug tsim nyob rau saum npoo ntawm weldments. Yog li ntawd, qhov saum npoo yuav tsum tau muab ntxuav ua ntej vuam, txwv tsis pub nws yog qhov nyuaj los lav qhov zoo.
2. Thaum vuam, qhov kub thiab lub sijhawm yuav tsum tsim nyog, thiab cov cua kub yuav tsum tsis sib xws
Thaum lub sij hawm welding, lub solder thiab hlau yuav tsum tau welded yog rhuab mus rau lub vuam kub, thiaj li hais tias cov molten solder wets thiab diffuses nyob rau saum npoo ntawm cov hlau yuav tsum welded thiab tsim ib tug hlau compound. Yog li ntawd, txhawm rau xyuas kom meej tias cov pob qij txha ruaj khov, yuav tsum muaj qhov tsim nyog rau qhov kub thiab txias.
Nyob rau ntawm qhov kub txaus, lub solder tuaj yeem ua kom ntub dej thiab tag nrho diffused los tsim cov txheej txheej alloy. Kev kub siab heev tsis yog qhov tsim nyog rau vuam. Lub sij hawm soldering muaj kev cuam tshuam zoo rau cov tin soldering, wettability ntawm cov khoom siv soldered, thiab tsim cov txheej txheem sib txuas. Kev paub zoo lub sijhawm vuam yog tus yuam sij rau kev vuam zoo.
3. Cov pob qij txha yuav tsum muaj lub zog txhua yam txaus
Txhawm rau kom ntseeg tau tias cov khoom yuav tsum tau welded yuav tsis poob los yog xoob thaum lawv raug kev co los yog kev cuam tshuam, cov pob qij txha yuav tsum muaj cov cuab yeej muaj zog txaus. Txhawm rau ua kom cov pob qij txha muaj zog txaus, txoj kev khoov cov hlau lead ntawm cov khoom yuav tsum tau welded thiab tom qab ntawd feem ntau siv tau, tab sis tsis txhob siv ntau dhau ntawm solder accumulator, uas yuav yooj yim ua rau virtual soldering thiab khoob. nruab nrab ntawm cov pob qij txha thiab cov pob qij txha. luv Circuit Court ntawm.
4. Vuam yuav tsum txhim khu kev qha kom ntseeg tau hluav taws xob conductivity
Txhawm rau ua kom cov pob qij txha muaj cov khoom siv hluav taws xob zoo, nws yog qhov tsim nyog los tiv thaiv kev sib tw virtual. False welding txhais tau hais tias lub solder thiab nto ntawm cov khoom yuav tsum tau welded tsis tsim ib tug alloy qauv, tab sis tsuas yog ua raws li cov saum npoo ntawm cov hlau yuav tsum tau welded. Thaum lub sij hawm vuam, yog tias tsuas yog ib feem ua ib qho hlau thiab qhov seem tsis tsim cov hlau, qhov sib koom ua ke no tseem tuaj yeem dhau tam sim no nyob rau lub sijhawm luv luv, thiab nws nyuaj rau nrhiav qhov teeb meem los ntawm kev ntsuas nrog lub ntsuas. Tab sis raws li lub sijhawm dhau mus, qhov chaw tsis muaj hlau yuav raug oxidized, thiab lub sijhawm no, qhov tshwm sim ntawm kev tawm thiab tawm yuav tshwm sim, uas yuav ua rau muaj teeb meem zoo ntawm cov khoom.
Nyob rau hauv luv luv, zoo zoo solder pob qij txha yuav tsum: ci thiab du solder pob qij txha; cov txheej txheej yog sib xws thiab nyias, thiab qhov kev faib ua feem rau qhov loj ntawm lub ncoo yog qhov tsim nyog, thiab cov txheej txheem ntawm kev sib tshuam yog faintly pom; lub solder yog txaus thiab nthuav tawm nyob rau hauv ib daim tiab zoo; tsis muaj kab nrib pleb, koob, thiab lwm yam qhov, tsis muaj flux residue. Daim duab 8 qhia txog qhov pom ntawm ib qho kev sib koom ua ke, qhov siab ntawm "daim tiab" yog li 1 txog 1.2 npaug ntawm lub vojvoog ntawm lub ncoo.
