Peb lub hauv paus ntsiab lus ntawm hluav taws xob soldering hlau vuam
1. Wetting: txheej txheem wetting txhais tau hais tias cov melted solder ntws nyob ib ncig ntawm cov pob zoo thiab crystallized khoob ntawm cov hlau nto ntawm lub hauv paus hlau los ntawm capillary quab yuam, yog li tsim ib tug adhesion txheej ntawm lub hauv paus hlau yuav tsum tau welded. , yog li ntawd lub solder thiab lub hauv paus hlau Cov atoms ntawm cov khoom hlau nyob ze rau ib leeg, mus txog qhov deb ntawm lub gravitational quab yuam ntawm lub atoms ua hauj lwm.
Ib puag ncig tej yam kev mob uas ua rau ntub dej: qhov saum npoo ntawm lub hauv paus hlau yuav tsum tau welded yuav tsum huv si thiab tsis muaj oxides los yog cov kab mob.
Daim duab piv txwv: Tso dej rau ntawm nplooj nplooj los ua cov dej ntws, uas yog, dej tsis tuaj yeem moisten cov paj. Tso dej rau ntawm paj rwb, thiab dej yuav nkag mus rau hauv paj rwb, uas yog, dej tuaj yeem moisten paj rwb.
2. Diffusion: Nrog kev nce qib ntawm wetting, kev sib nrig diffusion ntawm solder thiab base hlau atoms pib tshwm sim. Feem ntau cov atoms nyob rau hauv ib lub xeev ntawm thermal co nyob rau hauv lub lattice lattice, thaum kub nce. Lub atomic kev ua si yog intensified, thiaj li hais tias cov atoms nyob rau hauv lub molten solder thiab lub hauv paus hlau hla kev sib cuag nto thiab nkag mus rau hauv lub lattice lattice ntawm ib leeg. Qhov txav ceev thiab qhov ntau ntawm cov atom yog txiav txim siab los ntawm cov cua kub thiab lub sijhawm.
3. Metallurgical ua ke: Vim muaj kev sib nrig sib txawv ntawm cov solder thiab lub hauv paus hlau, ib txheej nruab nrab --- hlau compound yog tsim los ntawm ob lub hlau. Yuav kom tau txais kev sib koom ua ke zoo, cov hlau sib txuas yuav tsum tau tsim ntawm cov khoom siv hauv paus yuav tsum tau welded thiab solder. Yog li ntawd lub hauv paus hlau ua tiav ib qho ruaj khov metallurgical daim ntawv cog lus.
