Solder yog cov hlau fusible alloy siv los tsim kev ruaj ntseg ntawm cov hlau ua haujlwm. Solder yog melted nyob rau hauv thiaj li yuav ua raws li thiab txuas cov pieces tom qab txias, uas yuav tsum tau ib tug alloy haum rau siv raws li solder muaj ib tug qis melting point tshaj li cov khoom tau koom.
Yuav siv li cas?
Solder yog cov hlau alloy siv los tsim cov ntawv cog lus ruaj khov; xws li tooj liab koom rau hauv Circuit Court boards thiab tooj liab yeeb nkab txuas. Nws tseem tuaj yeem muab faib ua ob hom sib txawv thiab txoj kab uas hla, txhuas thiab txhuas tsis pub dawb thiab kuj tuaj yeem nyob nruab nrab ntawm.
Yuav ua li cas yog cov lus teb?
Dab tsi yog soldering? Dab tsi yog solder? Qhia teb. "Soldering" yogdaim ntawv kub qis ntawm vuam feem ntau siv los koom cov khoom siv hluav taws xob ua ke rau kev sib txuas mus tas li " Solder" yog ib qho tshwj xeeb alloy ntawm cov hlau tsim los yaj ntawm qhov kub thiab txias, ua kom muaj hluav taws xob txuas mus tas li.
Yuav ua li cas yog solder hauv chemistry?
Solder txhais tau tias yog cov khoom sib koom ua ke uas muaj cov ntsiab lus melting tsawg dua 475 ° C. Solder seals siv lub tshuab nqus tsev uas tsis tshua muaj melting point alloys ntawm indium, tin, gallium, txhuas, thiab lawv cov alloys.
khoom siv hluav taws xob yog dab tsi?
Soldering yog kev koom ua ke ntawm ob qhov chaw hlau uas siv tshuab thiab hluav taws xob, nrog rau kev siv hlau hu ua solder. … Lub solder yog melted siv ib tug soldering hlau. Flux yog siv los ntxuav thiab npaj cov chaw, uas tso cai rau lub melted solder ntws (los yog "ntub") thiab daim ntawv cog lus nrog cov hlau nto.
