Cov ntaub ntawv raw ntawm solder muab suav nrog cov hmoov txhuas alloy flux thiab qee qhov ntxiv. Alloy ham folder hmoov cov nyiaj rau ib qho kev faib tawm loj ntawm cov cam moo tshuaj, feem ntau yog 8% rau 90%, thaum cov nyiaj flux rau 10% mus rau 15%. Alloy ham ham hmoov yog ua los ntawm txau hauv cov roj inert. Feem ntau siv yog ob pawg loj: cov txhuas thiab tsis muaj Lead. Cov khoom xyaw tshwj xeeb suav nrog tin-lead, tin-nyiaj, tin-tooj liab, thiab lwm yam.
Tsis tas li ntawd, cov ham muab tshuaj txhuam tseem muaj lwm cov ntaub ntawv ua ke xws li cov neeg ua haujlwm xws li cov khoom siv thiab cov neeg sawv cev. Cov kev ua kom muaj xws li flux thiab antioxidants. Flux txhim kho kev ua haujlwm ntawm vuam tshuaj, thiab tshuaj tua kab mob tiv thaiv oxidation; Cov khoom siv hauv paus yog feem ntau hlau cov hmoov lossis alloys, uas cuam tshuam rau cov duab thiab kev ua tau zoo ntawm cov pob qij txha sib ntaus; Flow cov neeg sawv cev txhim kho cov wettabity thiab futility, thiab pab ua cov khaub ncaws sib luag sib luag. Cov ntaub ntawv raw ua ke ua ke kom ntseeg tau tias qhov zoo thiab cuam tshuam ntawm vuam.
