Koj puas to taub qhov solder ntawm hluav taws xob soldering hlau?
Solder yog ib qho hlau fusible uas ua rau cov khoom siv ua rau kev sib txuas rau cov ntsiab lus sib txuas ntawm lub rooj tsav xwm luam tawm. Tin (Sn) yog ib qho mos mos, malleable silver-dawb hlau nrog lub melting point ntawm 232 degree. Nws muaj cov tshuaj lom neeg ruaj khov ntawm chav sov, tsis yooj yim rau oxidize, tsis poob nws cov xim hlau, thiab muaj zog atmospheric corrosion kuj. Lead (Pb) yog lub teeb xiav-dawb hlau nrog lub melting point ntawm 327 degree. High-purity lead muaj muaj zog atmospheric corrosion kuj thiab zoo tshuaj stability, tab sis nws yog teeb meem rau tib neeg lub cev. Ntxiv ib qho kev faib ua feem ntawm cov hlau lead thiab ib qho me me ntawm lwm cov hlau rau tin tuaj yeem ua rau nws tsis tshua muaj melting point, zoo fluidity, muaj zog adhesion rau cov khoom thiab cov xov hlau, siab mechanical zog, zoo conductivity, tsis yooj yim rau oxidize, zoo corrosion kuj, kaj solder. pob qij txha Zoo nkauj solder, feem ntau hu ua solder. Solder tuaj yeem muab faib ua 15 hom raws li cov ntsiab lus tin, raws li cov ntsiab lus tin thiab impurities
Cov tshuaj muaj pes tsawg leeg muab faib ua S, A, B peb qib. Filiform solder yog feem ntau siv hauv phau ntawv soldering. (Tseem muaj ib puag ncig tus phooj ywg cov hlau lead-dawb solders uas nquag siv tam sim no)
