1. Flux ịgbado ọkụ ụkpụrụ
Flux nwere ike iburu mmetụta ịgbado ọkụ, n'ihi na atom metal dị nso na ibe ha mgbe mgbasa, mgbasa, infiltration na mmetụta ndị ọzọ.Na mgbakwunye na mkpa ọ dị izute mwepụ nke oxides na ihe ndị na-emetọ ihe na arụmọrụ arụ ọrụ, kamakwa izute ndị na-adịghị emebi emebi, mkpuchi, mmiri na-eguzogide mmiri, nkwụsi ike, adịghị emerụ ahụ, ịdị ọcha na ihe ndị ọzọ a chọrọ.N'ikwu okwu n'ozuzu, ihe ndị bụ isi ya bụ onye na-arụ ọrụ, ihe nkiri - ihe na-emepụta ihe, ihe mgbakwunye, ihe mgbaze na ihe ndị ọzọ.
2. Wepu oxide n'elu nke welded metal
Na gburugburu ikuku nkịtị, a na-enwekarị ụfọdụ oxides n'elu igwe nke igwe ịgbado ọkụ.Ndị a oxides ga-enwe mmetụta ụfọdụ na wetting nke ihe na-ere ahịa n'oge usoro ịgbado ọkụ, nke ga-emetụta usoro ịgbado ọkụ na nsonaazụ ịgbado ọkụ.Ya mere, flux kwesịrị inwe ike ibelata oxide, na ịgbado ọkụ nke PCBA nhazi nwere ike rụrụ na-ejikarị.
3. Gbochie oxidation nke abụọ
Na usoro ịgbado ọkụ nke PCBA nhazi, kpo oku dị mkpa.Otú ọ dị, na usoro ikpo ọkụ, ngwa ngwa oxidation ga-eme n'elu igwe n'ihi mmụba nke okpomọkụ.N'oge a, ọ dị mkpa ka ọ na-arụ ọrụ iji gbochie oxidation nke abụọ.
4. Belata erughị ala nke solder gbazere
N'ihi na nke anụ ahụ ụdị, a wụrụ awụ solder elu ga-enwe a ụfọdụ esemokwu, na elu esemokwu ga-eduga na ọsọ nke solder eruba na ịgbado ọkụ n'elu na-emetụta nkịtị wetting na ịgbado ọkụ usoro, na ọrụ nke flux na nke a. oge bụ iji belata erughị ala nke mmiri mmiri solder, nke mere na wettability nwere ike budata mma.
