Dab tsi yog qhov txawv ntawm qhov chaw nres tsheb tsis muaj hlau lead los ntawm qhov chaw nres tsheb hlau lead
Qhov tseeb, nws yog vim qhov sib txawv ntawm qhov kub thiab txias. Qhov ntsuas kub uas yuav tsum tau ua rau cov hlau tsis muaj hlau lead yog siab dua, feem ntau nyob ib ncig ntawm 250 degrees, thaum qhov kub ntawm cov hlau zoo tib yam yog 180 degrees, yog li qhov kub ntawm cov hlau tsis muaj hlau lead yog siab dua. , thiab cua kub ceev ntawm qhov chaw nres tsheb tsis muaj hlau lead yog sai dua. Tau kawg, muaj kev zam. Ntawm cov hlau lead-dawb solders, kuj tseem muaj cov kub kub uas nws cov ntsiab lus melting qis dua li cov hlau lead. Tab sis tus nqi ntawm no kub-kub solder yog kim heev.
Raws li kev hais lus, cov chaw nres tsheb tsis muaj hlau lead kuj tseem tuaj yeem ua tau nrog cov hlau lead hauv cov pob qij txha, vim tias qhov kub ntawm cov hlau lead-free soldering chaw nres tsheb tuaj yeem ncav cuag qhov melting point ntawm cov hlau lead. Tab sis qhov tseeb, tsis muaj leej twg siv nws zoo li no, vim tias ib zaug cov hlau lead-dawb solder yog soldered ntawm qhov chaw nres tsheb tsis muaj cov hlau lead, qhov chaw nres tsheb tsis muaj cov hlau lead yuav raug qias neeg thiab tsis tuaj yeem siv los ua ib puag ncig zoo. khoom.
Piv txwv li, cov hlau lead-dawb soldering tsis tuaj yeem ua tiav nrog lub chaw nres tsheb hlau lead, vim tias qhov kub ntawm qhov chaw nres tsheb soldering yuav tsis ncav cuag qhov kub ntawm cov hlau lead-free solder.
Qhov tseeb, nws tsuas yog nyob ntawm cov khoom siv los txiav txim siab qhov chaw nres tsheb siv los siv.
