Gịnị kpatara yareflow solderinga na-akpọ "reflow"?The reflow nke reflow soldering pụtara na mgbetapawa solderesịmde agbaze ebe nke solder mado, n'okpuru omume nke elu erughị ala nke mmiri mmiri tin na flux, mmiri mmiri tin reflows ka akụrụngwa atụdo na-etolite solder nkwonkwo, ikwe sekit A usoro nke osisi pads na components bụ. A na-akpọkwa usoro "reflow" n'ime otu dum.
1. Mgbe PCB osisi abanye na reflow kpo oku mpaghara, ihe mgbaze na gas na solder mado evaporate.N'otu oge ahụ, mmụgharị dị na tapawa solder na-edochi mpe mpe akwa ahụ, ihe mejupụtara ya na ntụtụ, na tapawa solder na-adị nro ma daa., Na-ekpuchi mpe mpe akwa, kewapụ mpe mpe akwa na ntụtụ akụrụngwa sitere na oxygen.
2. Mgbe PCB sekit osisi abanye na reflow soldering mkpuchi ebe, na PCB na components na-n'ụzọ zuru ezu preheated iji gbochie PCB si na mberede abanye na elu okpomọkụ ebe nke ịgbado ọkụ na imebi PCB na components.
3. Mgbe PCB banyere reflow soldering ebe, okpomọkụ na-ebili ngwa ngwa nke na solder mado rute a gbazee steeti, na mmiri mmiri solder wets na diffus na pads, akụrụngwa agwụ na atụdo nke PCB, na mmiri mmiri tin reflows na mixes. na-etolite solder nkwonkwo.
4. PCB na-abanye na mpaghara reflow jụrụ oyi, a na-agbanyekwa tin mmiri mmiri iji mee ka nkwonkwo solder sie ike site na ikuku oyi nke reflow soldering;n'oge a, reflow soldering agwụla.
