Kev taw qhia thiab lub hauv paus ntsiab lus ntawm qhov chaw nres tsheb tsis muaj hlau lead-free soldering
Taw qhia
Tom qab cov khoom siv hluav taws xob raug muab pov tseg, cov hlau lead hauv PCB solder yog yooj yim soluble hauv dej uas muaj oxygen. Kev ua qias tuaj ntawm cov dej, kev puas tsuaj rau ib puag ncig. Solubility ua rau nws nyob rau hauv tib neeg lub cev, ua rau cov hlab ntsha puas, ua rau sluggishness, ntshav siab, anemia, kev ua me nyuam tsis ua hauj lwm thiab lwm yam kab mob; Cov concentration ntau dhau yuav ua rau mob qog noj ntshav. Ua lub neej zoo, lub sijhawm xav tau cov khoom tsis muaj hlau lead. Raws li ib qho tseem ceeb txuas hauv kev tsim cov pCB Circuit Court boards, soldering yuav tsum tsis muaj hlau lead, yog li high-frequency lead-free soldering stations tau los ua.
txoj cai ua haujlwm
Piv nrog rau qhov kub thiab txias qhov chaw nres tsheb, cov chaw nres tsheb tsis muaj cov hlau lead tsis tshua muaj feem ntau siv cov cua kub tam sim no, nrog rau cov cua kub ceev thiab rov qab ceev kom ua tiav cov hlau lead-dawb soldering, thiab lub zog feem ntau yog siab li 90W{{6 }}W.
Cov kev ceev faj
Kev tswj kub ntawm cov hlau taub hau
Nyob ntawm qhov siv cov solder, nws yog ib qho tseem ceeb uas yuav tau xaiv qhov tsim nyog tshaj qhov ntsuas kub. Ua ntej ua haujlwm, nws yog ib qho tsim nyog los ntsuas qhov kub ntawm cov hlau taub hau nrog lub ntsuas kub ntawm lub taub hau.
Siv cov lus qhia zoo zoo soldering hlau
Cov hlau nplaum cuav, lub qhov taub (rau hauv cov tub ntxhais cua sov) yog qhov loj lossis me, thiab cov thickness ntawm lub casing kuj txawv. Tag nrho cov no ua rau qhov kev ua tau zoo ntawm cov hluav taws xob soldering hlau tsis tuaj yeem ua si, thiab qee zaum ua rau cov hluav taws xob soldering hlau tsis ua haujlwm.
Siv qhov sib txuam kov cov khoom cua sov
Vim tias cov qauv cua sov ntawm cov chaw siv hluav taws xob ntau zaus thiab qhov chaw kub kub tsis tu ncua yog qhov sib txawv. Yog li cov tes tuav ntawm lawv tsis yog universal.
