ʻO ke kuʻi ʻana ke kaʻina o ka hoʻohui ʻana i 2 metala me kekahi i kekahi no kahi hui ikaika a paʻa. Hana ʻia kēia me ka hoʻohana ʻana i ka metala filler.
Hoʻohana nui ʻia kēia ʻenehana o ka hoʻopili ʻana i nā metala me kekahi i ka uila. Hoʻohana nui ʻia ka paipu a me nā mea hao i kēia ʻano hana.
Ma muli o ka hihia, nā ʻano like ʻole o nā kahe hoʻohana ʻia. ʻO ka hoʻoheheʻe uila he kahua koʻikoʻi kahi e pono ai ka flux i hoʻohana ʻia i kekahi mau ʻano, e like me ka non-conductivity.
Ma kēia ʻatikala, e haʻi wau iā ʻoe e pili ana i ke ʻano o ka flux i hoʻohana ʻia i ka soldering electronics, a me kāu e noʻonoʻo ai ma mua o ka hoʻohana ʻana i kekahi o ia mau mea.
Ma kēia pou e uhi mākou:
No ke aha e koi ʻia ai ka flux ma ka uila uila?
ʻOiai ʻoe e hoʻāʻo e hoʻopiha i ka wahi hui o nā metala ʻelua me kekahi metala ʻē aʻe (ʻo ia ka mea e kūʻai aku ai), ʻo ka lepo a me nā ʻōpala ma kēlā mau ʻili metala ke keʻakeʻa nei i ka hana ʻana i kahi hui maikaʻi. Hiki iā ʻoe ke wehe a hoʻomaʻemaʻe i ka lepo non-oxidizing mai kēlā mau wahi maʻalahi, akā pono ʻoe e hoʻohana i ka flux ke hoʻāʻo nei ʻoe e wehe i ka oxidation.
Oxidation: He mea ino anei?
He mea maoli ka oxidation. Akā ʻaʻole ia manaʻo he maikaʻi nā mea a pau.
Hoʻopili nā metala āpau me ka oxygen i ka lewa a mai nā pūhui kemika paʻakikī ma ka ʻili metala paʻakikī ke wehe a paʻakikī loa ke kūʻai aku. Kāhea ʻia ʻo ʻOxidation he popo ma ka hao.
Hoʻohana i ka flux e wehe i ka oxidation
ʻO ka Flux kekahi mea hoʻohui kemika e hana me ka oxidation, ma lalo o ka wela kiʻekiʻe, ka hoʻoheheʻe ʻana, a me ka wehe ʻana i ka oxidation. Pono ʻoe e hana pinepine hoʻohana flux e hoʻomaʻemaʻe i ka oxidation mai kou piko hao hao no ka mea ʻoi aku ka kiʻekiʻe o ka wela.
E hoʻomanaʻo i kēia inā makemake ʻoe e hana i kāu hao hao ponoʻī.
ʻO nā ʻano like ʻole o ka flux i ka uila uila
ʻAʻole ʻano like ka flux i hoʻohana ʻia ma nā papa kaapuni uila me nā mea i hoʻohana ʻia ma nā uwea no ka mea makemake lākou i nā waiwai like ʻole mai ka flux.
Ma lalo, e haʻi wau iā ʻoe e pili ana i nā ʻano flux āpau i loaʻa ma ka mākeke no ka hoʻoheheʻe uila.
Fluks Rosin
ʻO ka paʻi ʻana i nā mea ʻē aʻe a pau e pili ana i ka makahiki he rosin flux.
I nā lā mua o ka hana ʻana, ua hana ʻia ka rosin fluxes mai ke kohu pine. Ma hope o ka ʻohi ʻia ʻana o ke kohu, hoʻomaʻemaʻe ʻia a hoʻomaʻemaʻe ʻia i loko o ka rosin flux.
Eia nō naʻe, i kēia mau lā, ua hui pū ʻia nā mea ʻokoʻa ʻē aʻe me nā kohu pine i hoʻomaʻemaʻe ʻia e hoʻohua ai i ka rosin flux.
Huli ka waiʻala Rosin i ʻakika wai a kahe maʻalahi ke wela. Akā, ma ka hoʻolili ʻana, lilo ia i mea paʻa a inert.
He mea maikaʻi loa ia i ka wehe ʻana i ka oxidation mai nā metala. Ma hope o ka hoʻohana ʻana iā ia ma nā kaapuni, hiki iā ʻoe ke waiho iā ia i kona ʻano paʻa ʻole. ʻAʻole ia e hana me kekahi mea ʻē aʻe inā ʻaʻole lawa ka wela e lilo ai i ʻakika.
Inā makemake ʻoe e wehe i ke koena ma hope o ka hoʻohana ʻana i ka rosin flux, pono ʻoe e hoʻohana i ka waiʻona, no ka mea ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai. No laila pono ʻoe e hoʻohana i ka waiʻona ma mua o ka wai maʻemaʻe.
Akā, ʻaʻohe pōʻino i ka waiho ʻana i ke koena e like me ia, ke ʻole ʻoe makemake e hana i kahi hana naʻauao o ka mālama ʻana i kāu papa kaapuni.
ʻO ka waiʻakika organik
Hoʻohana ʻia nā ʻakika organik e like me ka waikawa citric, ka waikawa lactic, a me nā ʻakika stearic e hana i kēia ʻano kahe. ʻO ke ʻano nāwaliwali o kēia mau waikawa, i hui pū ʻia me ka waiʻona isopropyl a me ka wai, e hoʻokumu i nā kahe waika organik.
ʻO ka pōmaikaʻi nui loa o nā kahe wai ʻawaʻawa ʻo ia ka hiki ke hoʻoheheʻe ʻia i ka wai, ʻaʻole like me ka rosin flux.
Ma waho aʻe o kēlā, ʻoiai ʻoi aku ka kiʻekiʻe o ka waiwai ʻawaʻawa o nā kahe waika organik ma mua o nā fluxes rosin, ʻoi aku ka ikaika. ʻO ka hopena, hiki iā lākou ke hoʻomaʻemaʻe i nā oxides mai nā ʻili metala me ka wikiwiki.
E hoʻohui i kēia mana hoʻoneʻe oxidation me kona ʻano soluble, a loaʻa iā ʻoe kahi koena flux maʻalahi e hoʻomaʻemaʻe. ʻAʻole pono ka waiʻona!
Eia naʻe, hiki mai kēia pōmaikaʻi hoʻomaʻemaʻe ma ke kumu kūʻai. Nalo ka waiwai non-conductivity o ke koena o ka rosin flux no ka mea he uila uila a hiki ke hoʻopili i ka hana holoʻokoʻa a me ka hana o kahi kaapuni.
No laila e hōʻoia ʻoe e wehe i ke koena flux ma hope o ke kūʻai ʻana.
ʻAʻohe-maʻemaʻe kahe
E like me ka inoa i hōʻike ʻia, ʻaʻole pono ʻoe e hoʻomaʻemaʻe i ke koena mai kēia ʻano o ka flux. Hoʻokumu ia i kahi nui liʻiliʻi i hoʻohālikelike ʻia me nā 2 fluxes ʻē aʻe.
Hoʻokumu ʻia ka flux ʻaʻohe maʻemaʻe ma luna o nā waikawa organik a me kekahi mau mea kemika. Hele pinepine kēia i nā syringes no ka maʻalahi.
No nā kaapuni e hoʻohana ana i ka ʻenehana mauna i luna, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i kēia ʻano o ka flux.
Eia nō hoʻi, ʻo ke ʻano o ka papa kiʻi pōleʻa he ʻano o ka papa i kau ʻia ma ka ʻaoʻao e pōmaikaʻi nui ana i nā kahe maʻemaʻe ʻole. ʻO ka liʻiliʻi o ke koena i hana ʻia ʻaʻole ia he conductive a corrosive. Hiki iā ʻoe ke hoʻohana iā lākou ma nā papa i ʻoi aku ka paʻakikī ma hope o ke kau ʻana.
Eia nō naʻe, ʻike kekahi mau mea hoʻohana i ka nui kamahaʻo o ke koena paʻakikī e wehe, ʻokoʻa ka conductive.
E akahele i ka hoʻohana ʻana i kēia mau fluxes ma nā papa analog me ka impedance kiʻekiʻe. Manaʻo mākou e hana hou i ka nīnau ma mua o ka hoʻohana ʻana i ka flux maʻemaʻe ʻole āu e manaʻo nei e hoʻohana.
Ke 'ano o ke ku'i 'ana e pale 'ia i ka wiliwili 'ana i nā mea uila: Inorganic acid flux
Hoʻopuka ʻia nā kahe waika inorganic mai ka hui ʻana o nā ʻakika ikaika me (akā ʻaʻole i kaupalena ʻia i) waika hydrochloric.
Pono ʻoe e hōʻalo i ka hoʻoheheʻe inorganic ma nā kaapuni a i ʻole nā ʻāpana uila ʻē aʻe, no ka mea, hiki ke ʻino ka flux a me kona koena. No nā metala ikaika, ʻaʻole nā ʻāpana uila.
E nānā i ka mea hoʻohana YouTube SDG Electronics 'wikiō ma ka flux maikaʻi loa no ke kūʻai ʻana:
E hoʻohana i ke ʻano kūpono no ka hana
E like me kāu e ʻike ai, loaʻa i nā ʻano flux nā mea maikaʻi a me nā hemahema i ka wā e hiki mai ana me ka hoʻohana ʻana i ka flux no ke kūʻai ʻana. Loaʻa iā ʻoe kahi laulā e koho ai i ka hana ʻana i kāu hana kūʻai ʻana ma ka uila.
ʻAʻole hiki i kekahi ke haʻi aku i kekahi o ia mau fluxes ʻo ia ka mea maikaʻi loa ma waho, no ka mea e koi ʻia nā hana ʻokoʻa i nā fluxs ʻokoʻa.
Inā ʻoe e hana ma nā kaʻapuni e hoʻohana ana i ka ʻenehana mauna-luna, ʻo kāu koho maikaʻi loa ʻo ia ka flux maʻemaʻe ʻole. Akā e makaʻala i ke koena mea ʻē aʻe.
A no nā kaapuni ʻē aʻe, hiki iā ʻoe ke koho i kekahi mea ma waena o ka flux acid organik a me ka flux rosin. He hana maikaʻi loa lāua ʻelua!
ʻO wau ʻo Joost Nusselder, ka mea nāna i hoʻokumu i ke Kauka Mea Hana, mea kūʻai maʻiʻo, a me ka makuakāne. Makemake au i ka hoʻāʻo ʻana i nā mea hana hou, a me kaʻu hui ua hana au i nā ʻatikala blog hohonu mai ka makahiki 2016 e kōkua i ka poʻe heluhelu kūpaʻa me nā mea hana a me nā ʻōlelo aʻoaʻo.
