1. ʻO ka loina hoʻoheheʻe Flux
Hiki i ka Flux ke hoʻopaʻa i ka hopena kuʻi, no ka mea, ua kokoke nā mea metala i kekahi i kekahi ma hope o ka diffusion, dissolution, infiltration a me nā hopena ʻē aʻe.Ma waho aʻe o ka pono e hoʻokō i ka wehe ʻana o nā oxides a me nā mea haumia i ka hana hoʻāla, akā e hālāwai pū me ka non-corrosive, insulation, moisture resistance, stability, harmlessness, pure a me nā koi ʻē aʻe.ʻO ka mea maʻamau, ʻo kāna mau mea nui he mea hana ikaika, kiʻiʻoniʻoni - nā mea hana, additives, solvents a pēlā aku.
2. Wehe i ka oxide ma ka ʻili o ka metala welded
I ka ea maʻamau, aia kekahi mau oxides ma ka ʻili metala o ka pā kuʻi.E loaʻa i kēia mau oxides kekahi hopena i ka pulu ʻana o ka solder i ka wā o ke kaʻina hana kuʻi, e hoʻopilikia i ke kaʻina hana a me nā hopena welding.No laila, pono e hiki i ka flux ke hōʻemi i ka oxide, a hiki ke hoʻokō maʻamau ka hoʻopili ʻana o ka hana PCBA.
3. Kāohi i ka lua o ka oxidation
I ke kaʻina hana hoʻoheheʻe o ka hana PCBA, pono ka hoʻomehana.Eia nō naʻe, i ke kaʻina o ka hoʻomehana ʻana, e hiki mai ka oxidation wikiwiki ma ka ʻili metala ma muli o ka piʻi ʻana o ka mahana.I kēia manawa, pono ka flux e pāʻani i ka pale ʻana i ka oxidation lua.
4. E ho'ēmi i ka manaʻo o ka solder hehee
Ma muli o ke ʻano o ke kino, e loaʻa i ka ʻili i hoʻoheheʻe ʻia i kahi ʻano haʻalulu, a ʻo ka ʻili o ka ʻili e alakaʻi i ka wikiwiki o ka solder kahe i ka ili kuʻi e hoʻopili i ka pulu maʻamau i ke kaʻina hana kuʻi, a me ka hana o ka flux i kēia. ʻO ka manawa e hōʻemi i ka ʻili o ka wai solder, i hiki ke hoʻomaikaʻi nui ʻia ka wettability.
