Ukugcina indawo osebenza kuyo ihlanzekile lapho uzama i-solder kubalulekile njengokugcina ipuleti lelayisense emotweni yakho. Futhi angihlekisi okuncane, umthethosivivinywa wakho wamanje uzonyukela phezulu nge-solder ehlulekile. Uma ungasebenzisi i-flux ukuhlanza indawo yakho i-soldering izophuma ngaphambi kokuthi wazi.
Ngaphandle kwalokho, izinsimbi ezishisayo zivame ukwakha ama-oxide lapho kuhlangana nomoya. Lokho kubangela ukuthi i-solder yehluleke isikhathi esiningi. Kulezi zinsuku kunezinhlobo ezimbalwa ze-solder laphaya. Ake sixoxe ngabo.
Kulokhu okuthunyelwe sizomboza:
Izinhlobo zeSoldering Flux
Ama-flux wokugcwala ahluka kakhulu ngokusebenza kwawo, amandla, umthelela kukhwalithi ye-solder, ukwethembeka, nokuningi. Ngenxa yalokhu, awukwazi ukusebenzisa noma iyiphi ukuhamba i-ejenti yezintambo ze-solder noma izingxenye ze-electronic. Ngokusekelwe emsebenzini wabo wokuguquguquka, i-soldering flux empeleni iwela ezigabeni ezilandelayo eziyisisekelo:
I-Rosin Flux
Bangu izinhlobo ezehlukene zokuhamba kwe-soldering kagesi, i-rosin flux ingenye yezidume kakhulu kubo. Into eyinhloko ekubhebhetheni kwe-rosin yi-rosin ekhishwe kwi-pinesap elungisiwe. Ngaphandle kwalokho, iqukethe isithako esisebenzayo i-abietic acid kanye nama-asidi emvelo ambalwa. Iningi le-rosin flux linezishoshovu kuzo ezenza ukuthi ukucucuza kukwazi ukwehlisa amandla futhi kuhlanzeke izindawo ezifakwe kuseli. Lolu hlobo lungahlukaniswa lube yizinhlobo ezintathu ezingaphansi:
I-Rosin (R) i-Flux
Le rosin (R) flux yakhiwe kuphela nge-rosin futhi ayisebenzi kangako phakathi kwezinhlobo ezintathu. Isetshenziselwa kakhulu ukugoqa izinsimbi zethusi, ama-PCB, nezinye izinhlelo zokusebenza zokufaka isandla. Imvamisa, isetshenziswa endaweni esivele ihlanziwe nge-oxidation encane. Inzuzo enkulu yayo ukuthi ayishiyi noma iyiphi insalela ngemuva.
I-Rosin ngobumnene iyasebenza (RMA)
I-Rosin flux eyenziwe yasebenza kancane inezisebenzisi ezanele ukuhlanza izindawo ezingcolile ngokulingene. Noma kunjalo, imikhiqizo enjalo ishiya izinsalela eziningi kunanoma yikuphi okunye ukugeleza okuvamile. Ngakho-ke, ngemuva kokusebenzisa, kufanele uhlanze indawo nge-flux cleaner ukuvimbela noma yikuphi ukonakala kwesekethe noma izingxenye.
I-Rosin yenziwe yasebenza (RA)
I-rosin yenziwe yasebenza kakhulu phakathi kwezinhlobo ezintathu zemikhuhlane ye-rosin. Ihlanza okungcono kakhulu futhi inikele nge-soldering enhle kakhulu. Lokhu kuzenza zilungele ukuhlanzwa kanzima ukuhlanza izindawo ezinama-oxide amaningi akhona. Ngasohlangothini lwe-flip, lolu hlobo aluvamile ukusetshenziswa njengoba luvame ukushiya inani elikhulu lezinsalela ngemuva.
I-Water Soluble Flux noma i-Organic Acid Flux
Lolu hlobo ngokuyinhloko luqukethe i-organic acid ebuthakathaka futhi lunyibilika kalula emanzini nase-isopropyl alcohol. Ngakho-ke, ungasusa izinsalela ze-flux usebenzisa amanzi ajwayelekile kuphela. Kepha kufanele uqaphele ukuthi izingxenye azimanzi.
Ngokwengeziwe, lolu hlobo lunamandla amakhulu okucekela phansi kunama-flux-based fluxes. Ngenxa yalokhu, bashesha kakhulu ekususeni ama-oxide ngaphezulu. Noma kunjalo, uzodinga ukuvikelwa okwengeziwe ngesikhathi sokuhlanzwa kwe-PCB ukugwema ukungcoliswa kwe-flux. Futhi, ngemuva kokufaka i-soldering, iminonjana yensalela yokugeleza kufanele ihlanzwe.
Okungajwayelekile I-Acid Flux
I-inorganic acid fluxes yenzelwe ukugoqa okushisa okuphezulu okunzima ukubopha. Lezi zonakalisa kakhulu noma ziqine kakhulu kunezinhlayiya eziphilayo. Ngaphandle kwalokho, zisetshenziselwa izinsimbi ezinamandla futhi zisiza ukuqeda inani elikhulu lama-oxide kusuka kuzinsimbi ezine-oxidized. Kepha, lezi azilungele kangcono imihlangano ye-elekthronikhi.
I-Flux engahlanzekile
Kulolu hlobo lokugeleza, ukuhlanza akudingeki ngemuva kokufaka i-soldering. Idizayinelwe ngokukhethekile ukuba nesenzo esimnene. Ngakho-ke noma ngabe kukhona okusele okuncane okusele, ngeke kubangele umonakalo ezingxenyeni noma kumabhodi. Ngalezi zizathu, lezi zilungele ukusetshenziswa kwe-automated soldering, i-wave soldering, kanye ne-surface mount PCBs.
Umhlahlandlela Oyisisekelo | Ungayisebenzisa Kanjani i-Flux yokuSoldering
Njengoba ubona kuningi izinhlobo ezehlukene zokuhamba kwe-soldering kagesi itholakala ngemidwebo ehlukahlukene njengoketshezi noma unamathisele. Futhi, ngezinqubo ezahlukahlukene ze-soldering flux isetshenziswa ngokuhlukile. Ngakho-ke, ukuze kube lula kuwe futhi uvikele ukudideka, nakhu sithola umhlahlandlela wesinyathelo ngesinyathelo wokusebenzisa i-soldering flux.
Khetha i-Flux efanelekayo bese uhlanza i-Surface
Ekuqaleni, khetha ukugeleza okufanelekile komsebenzi wakho we-soldering ohlwini lwethu lwezinhlobo ezahlukahlukene zokushintshashintsha kwe-soldering. Okulandelayo, kufanele uhlanze indawo yensimbi ukuze ingabi nalo uthuli, ukungcola, noma i-oxidation eyeqile.
Vala indawo ngeFlux
Ngemuva kwalokho, udinga ukufaka ungqimba we-flux ekhethiwe ebusweni lapho uzobe uthwebula khona. Qaphela ukuthi kufanele uyimboze ngokuphelele indawo. Kulesi sigaba, akufanele usebenzise ukushisa.
Sebenzisa Ukushisa nge-Soldering Iron
Okulandelayo, qala insimbi ukuze ichopho lishise ngokwanele ukuncibilikisa ukugeleza ngokuxhumana. Beka i-ayoni ngaphezulu kwe-flux bese uyivumela ukuthi incibilike ukugeleza kube yifomu eliketshezi. Lokhu ngeke kusize kuphela ukuqeda ungqimba lwamanje lwe-oxide, kodwa futhi kuzovimbela i-oxidization yesikhathi esizayo kuze kube yilapho i-flux ihlala. Manje, ungaqala inqubo nokunamathisela ngomthofu.
Izinsimbi Zokugcoba ngeSoldering Flux
Kusetshenziswa ukuguquguquka kokushintshanisa ngenkathi izintambo ze-soldering noma izixhumi kunokwehluka okumbalwa kunqubo ejwayelekile esichaze ngaphambili. Njengoba lezi zibucayi kakhulu, izinguquko ezimbalwa zingalimaza izintambo. Kungakho, ngaphambi kokusebenzisa ukugeleza kwezintambo, qiniseka ukuthi wenza inqubo efanele.
Khetha i-Right Flux
Njengoba izintambo eziningi zintekenteke futhi zizacile, ukusebenzisa noma yini engonakalisa kakhulu kungalimaza isekethe yakho. Ngakho-ke, ochwepheshe abaningi bayeluleka ngokukhetha ukucucuza okususelwa ku-rosin ngoba kuyimbangela encane kakhulu.
Hlanza futhi uhlanganise izintambo
Ngokuyinhloko qiniseka ukuthi ucingo ngalunye luhlanzekile. Manje, shintsha ukuphela okuveziwe kocingo ngalunye. Qhubeka uphendukezela izintambo ngapha nangapha kuze kube yilapho ungasaboni iziphetho ezicijile. Futhi uma ufuna ukubeka i-tubing-sink-tubing phezu kwe-soldering yakho, yenza lokhu ngaphambi kokuhlanekezela izintambo. Qinisekisa ukuthi i-tubing incane futhi incipha ngokuqinile ezintanjeni.
Faka i-Soldering Flux ezintanjeni
Ukuze ugqoke izintambo, sebenzisa iminwe yakho noma ibhulashi lokupenda elincane ukukha inani elincane lokugeleza bese usakaza endaweni. I-Flux kufanele imboze ngokuphelele izintambo. Ukungasho, kufanele usule ukugeleza okweqile ngaphambi kokuqala ukugoqa.
Ncibilikisa i-Flux nge-Soldering Iron
Shisisa i-ayoni manje futhi uma selishisa, cindezela insimbi ohlangothini olulodwa lwezintambo. Qhubeka nale nqubo kuze kube yilapho ukucibilika kuncibilika ngokugcwele bese kuqala ukubhuza. Ungafaka inani elincane le-solder esicongweni sensimbi ngenkathi uyicindezela ukuze ifake ucingo ukusheshisa ukudluliswa kokushisa.
Faka iSolder Ezintanjeni
Ngenkathi insimbi icindezelwe izingcingo ohlangothini olungezansi, faka ezinye solder ungene olunye uhlangothi lwezintambo. I-solder izoncibilika ngokushesha uma insimbi ishisa ngokwanele. Qiniseka ukuthi uzobeka i-solder eyanele ukumboza ukuxhumana ngokuphelele.
Vumela iSolder Harden
Manje thatha i-iron soldering uhambe nayo ubekezele ukuze i-solder iphole. Njengoba ziphola ungazibona ziqina. Lapho i-solder isethiwe, funa noma iyiphi ucingo oluveziwe. Uma kukhona, phakela i-solder ngaphezulu kuwo bese uwavumela aqinise.
Isiphetho
Ubuciko bokugcoba buyinto elula, kepha iphutha elincane lingaba sendleleni yokwakha isibopho esifanelekile. Ngakho-ke, kubaluleke kakhulu ukwazi ukusetshenziswa okufanele kwe-soldering flux. Noma ngabe usaqala noma awuwona uchwepheshe, ngethemba, umhlahlandlela wethu onemininingwane ukusizile ngokwanele ukuqonda ngokuphelele zonke izici ezidingekayo zokuwusebenzisa.
Khumbula ukuthi i-soldering flux iyonakalisa futhi ingalimaza isikhumba sakho uma sisesimweni soketshezi noma sishisiwe. Kepha awudingi ukuthi ukhathazeke uma ine-pasty texture. Ngokuphepha okwengeziwe, sebenzisa amagilavu esikhumba angamelana nokushisa ngenkathi usebenza.
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
