Dab tsi yog solder thiab flux
(1) Solder: Rau vuam cov khoom siv hluav taws xob, cov xaim hlau nrog cov rosin core feem ntau yog siv. Cov hlau nplaum no muaj qhov taw tes qis thiab muaj rosin flux, uas yog qhov yooj yim heev rau siv.
(2) Flux: Feem ntau siv flux yog rosin lossis rosin dej (solve rosin hauv cawv). Kev siv cov flux tuaj yeem pab tshem tawm cov oxides ntawm cov hlau saum npoo, uas yog qhov zoo rau kev siv vuam thiab tiv thaiv qhov kawg ntawm cov hlau soldering. Solder paste kuj tseem siv tau thaum soldering cov khoom loj lossis cov xov hlau. Tab sis nws yog corrosive rau ib qho twg, thiab cov seem yuav tsum tau muab tshem tawm hauv lub sijhawm tom qab vuam.
