Kusunga malo anu ogwirira ntchito oyera mukamayesa kusungunula ndikofunikira monga kusungitsa mbale yololeza pagalimoto yanu. Ndipo sindikunyoza pang'ono, ndalama yanu yapano ikwera chifukwa cha solder yemwe walephera. Ngati simukugwiritsa ntchito kutulutsa kutsuka malo anu, soldering idzatuluka musanadziwe.
Kuphatikizanso apo, zitsulo zotentha zimakonda kupanga ma oxides akagwirizana ndi mpweya. Izi zimapangitsa kuti solder alephere nthawi zambiri. Masiku ano pali mitundu ingapo yosungunuka kunja uko. Tiyeni tikambirane za iwo.
Mu positi iyi tikambirana:
Mitundu ya Soldering Flux
Soldering fluxes amasiyana kwambiri malinga ndi momwe amagwirira ntchito, mphamvu, zimakhudza khalidwe la soldering, kudalirika, ndi zina. Pachifukwa ichi, simungagwiritse ntchito chilichonse ikuyenda wothandizira ku mawaya a solder kapena zida zamagetsi. Kutengera ntchito yawo yosinthira, kusinthasintha kwa soldering kumagwera m'magulu otsatirawa:
Rosin Flux
Pali Mitundu yosiyanasiyana yamagetsi yamagetsi yamagetsi, rosin flux ndi imodzi mwodziwika kwambiri. Choyambirira mu rosin flux ndi rosin yemwe amachokera ku pinesap woyengedwa. Kupatula apo, ili ndi zinthu zomwe zimagwiritsidwa ntchito ndi abietic acid komanso ma acid ochepa. Mitundu yambiri ya rosin imakhala ndi zotsegulira zomwe zimathandizira kuti kamwedwe kameneka kachulukitse komanso kuyeretsa malo osungunuka. Mtundu uwu ukhoza kugawidwa m'magulu atatu:
Rosin (R) Kutuluka
Kutulutsa kwa rosin (R) kumangokhala ndi rosin ndipo sikugwira ntchito pakati pa mitundu itatu. Amagwiritsidwa ntchito potengera waya wamkuwa, ma PCB, ndi ntchito zina zogwiritsira ntchito pamanja. Nthawi zambiri, imagwiritsidwa ntchito pamalo oyera kale omwe ali ndi makutidwe ndi okosijeni ochepa. Ubwino wake waukulu ndikuti sichisiya zotsalira zilizonse.
Rosin Modekha (RMA)
Kutulutsa kofatsa kwa Rosin kuli ndi oyambitsa okwanira kuyeretsa malo onyansa pang'ono. Komabe, zoterezi zimasiya zotsalira zambiri kuposa kusintha kwina kulikonse. Chifukwa chake, mutagwiritsa ntchito, muyenera kuyeretsa pamwamba ndi kutsuka kwa madzi kuti mupewe kuwonongeka kwa dera kapena zinthu zina.
Rosin adamulowetsa (RA)
Rosin adamulowetsa ndi yogwira kwambiri mwa mitundu itatu ya kamwazi rosin. Imatsuka bwino kwambiri komanso imapereka soldering yabwino kwambiri. Izi zimawapangitsa kukhala abwino kuyeretsa molimbika kuyeretsa malo okhala ndi ma oxide ambiri. Pazithunzi, mtunduwu sugwiritsidwa ntchito kawirikawiri chifukwa umasiya zotsalira zambiri kumbuyo.
Kusungunuka kwa Madzi Kusungunuka kapena Organic Acid Flux
Mtunduwu umakhala ndi ofooka organic acid ndipo amasungunuka mosavuta m'madzi ndi isopropyl mowa. Chifukwa chake, mutha kuchotsa zotsalira za flux pogwiritsa ntchito madzi wamba. Koma muyenera kusamala kuti zomwe zimaphatikizazo sizinyowa.
Kuphatikiza apo, mtundu uwu umakhala ndi mphamvu zowononga kuposa ma flux otumphuka. Chifukwa cha izi, ali achangu kwambiri pochotsa ma oxidi pamtunda. Ngakhale, mudzafunika chitetezo chowonjezera pakutsuka kwa PCB kuti mupewe kuwonongeka kwa kamwazi. Komanso, mutasungunuka, zotsalira za zotsalira ziyenera kutsukidwa.
Magetsi Acid Flux
Mafunde amadzimadzi amadzimadzi amapangidwira kutentha kwambiri komwe kumakhala kovuta kulumikizana. Izi zimawononga kwambiri kapena zamphamvu kuposa ma organic fluxes. Kuphatikiza apo, amagwiritsidwa ntchito pazitsulo zolimba ndikuthandizira kuthana ndi ma oxide ambiri pazitsulo zazitsulo kwambiri. Koma, izi sizoyenera bwino pamisonkhano yamagetsi.
Kutuluka Osayera
Pamtundu woterewu, kuyeretsa sikofunikira pambuyo pa soldering. Amapangidwa kuti azikhala ofatsa. Chifukwa chake ngakhale mutatsala pang'ono zotsalira, sizingawononge ziwalo kapena matabwa. Pazifukwa izi, izi ndi zabwino pazogwiritsira ntchito makina opanga ma soldering, ma soldering, ndi ma PCB apamwamba.
Malangizo Oyambirira | Momwe Mungagwiritsire Ntchito Flux pa Soldering
Monga mukuwonera pali zambiri mitundu yosiyanasiyana ya kamwazi kwa soldering pakompyuta kupezeka m'njira zosiyanasiyana monga madzi kapena phala. Ndiponso, pazinthu zosiyanasiyana za soldering flux imagwiritsidwa ntchito mosiyana. Chifukwa chake, kuti mukhale osavuta komanso kuti mupewe chisokonezo, apa tikupita pagawo loti mugwiritse ntchito soldering flux.
Sankhani Flux Yoyenera ndikuyeretsa Pamwambapa
Poyamba, sankhani kutuluka koyenera kwa ntchito yanu ya soldering pamndandanda wathu wamitundu yosiyanasiyana ya soldering. Kenako, muyenera kuyeretsa chitsulo kuti chisakhale fumbi, chinyezi, kapena kutsekemera kwambiri.
Phimbani Malo ndi Flux
Pambuyo pake, muyenera kuyika gawo limodzi lamasamba omwe mwasankha pamwamba pomwe mupanga soldering. Dziwani kuti muyenera kuphimba kwathunthu malowo. Pakadali pano, simuyenera kuthira kutentha.
Ikani Kutentha ndi Soldering Iron
Kenaka, yambani chitsulo kuti nsaluyo ikhale yotentha mokwanira kuti isungunuke ndi kukhudzana. Ikani chitsulo pamwamba pa madziwo ndikuwalola kuti asungunuke kutuluka kwake kukhala mawonekedwe amadzi. Izi sizikuthandizira kuthana ndi ma oxide osanjikiza pano, komanso zithandizira kuti oxidization yamtsogolo isanatuluke. Tsopano, mutha kuyambitsa ndondomeko ya soldering.
Soldering Mawaya okhala ndi Soldering Flux
Kugwiritsa ntchito soldering flux pomwe mawaya a soldering kapena zolumikizira sizimasiyana kwenikweni ndi zomwe tidanena kale. Popeza izi ndizocheperako, kusintha pang'ono kumatha kuwononga mawaya. Ichi ndichifukwa chake musanagwiritse ntchito mawaya, onetsetsani kuti mukuchita zolondola.
Sankhani Flux Yoyenera
Ma waya ambiri amakhala osalimba komanso owonda, kugwiritsa ntchito chilichonse chomwe chimawononga kungawononge dera lanu. Chifukwa chake, akatswiri ambiri amalangiza kusankha kutsekemera kochokera mu rosin kwa soldering chifukwa ndikowononga pang'ono.
Sambani ndi Kuphatikiza Mawaya
Makamaka onetsetsani kuti waya iliyonse ndi yoyera. Tsopano, pindani malekezero owonekera a waya uliwonse palimodzi. Pitirizani kupotoza mawayawo mozungulira mpaka simungathe kuwona malekezero ake. Ndipo ngati mukufuna kuyika machubu otenthetsera kutentha kwanu, chitani izi musanapotoze mawaya. Onetsetsani kuti tubing ndi yaying'ono ndipo ikuchepa mwamphamvu ku mawaya.
Ikani Soldering Flux pamawaya
Kuti muvale ma waya, gwiritsani zala zanu kapena burashi laling'ono kuti mupeze pang'ono ndikuwayala kuderalo. Flux iyenera kuphimba kwathunthu mawaya. Osanena, muyenera kupukuta kuchuluka kochuluka musanayambe kusungunula.
Sungunulani Flux ndi Soldering Iron
Kutenthetsani chitsulo tsopano ndipo mukangotentha, kanikizani chitsulo mbali imodzi ya mawaya. Pitirizani ntchitoyi mpaka kusungunuka kwathunthu kusungunuka ndikuyamba kuphulika. Mutha kuyika solder pang'ono kumapeto kwa chitsulo kwinaku mukukanikiza ku waya kuti ifulumizitse kutentha.
Ikani Solder mu Ma waya
Chitsulo chikakanikizika ndi waya pansi, ikani zina solder kumtunda mbali inayo ya mawaya. Solder amasungunuka nthawi yomweyo ngati chitsulo chitentha mokwanira. Onetsetsani kuti muika solder yokwanira kuti muthe kulumikiza kwathunthu.
Lolani Solder Harden
Tsopano tengani chitsulo chosungunulira ndi kuleza mtima kuti solder azizire. Akamazizira amatha kuwawona akuuma. Solder ikakhazikitsidwa, yang'anani waya aliyense wowonekera. Ngati alipo, idyetsani solder pamenepo ndikuwalola kuti aume.
Kutsiliza
Zojambulajambula ndizosavuta, komabe kulakwitsa pang'ono kumatha kukhala njira yopangira mgwirizano wabwino. Chifukwa chake, ndikofunikira kwambiri kudziwa kugwiritsa ntchito koyenera kwa soldering flux. Kaya ndinu oyamba kumene kapena osakhala akatswiri, mwachiyembekezo, wowongolera wathuyu wakuthandizani mokwanira kuti mumvetsetse zofunikira zonse pakugwiritsa ntchito.
Kumbukirani kuti soldering flux imatha kuwononga ndipo imatha kuwononga khungu lanu ngati lili lamadzi kapena lotentha. Koma simuyenera kuda nkhawa ngati ili ndi mawonekedwe abusa. Kuti mukhale otetezeka kwambiri, gwiritsani ntchito magolovesi achikopa osagwira ntchito mukamagwira ntchito.
