I-soldering yinqubo yokuhlanganisa izinsimbi ezi-2 enye kwenye ukuze kube yilunga eliqinile neliqinile. Lokhu kwenziwa ngokusebenzisa i-filler metal.
Le nqubo yokuxhuma izinsimbi nenye isetshenziswa kabanzi kuma-electronics. Amapayipi kanye nensimbi nawo asetshenziswa kakhulu le nqubo.
Kuye ngecala, izinhlobo ezahlukene ze umkhuhlane zisetshenziswa. I-electronics soldering iyinkambu ebucayi lapho ukugeleza okusetshenzisiwe kufanele kube nezibaluli ezithile, njengokungaqhubeki.
Kulesi sihloko, ngizokutshela mayelana nezinhlobo ze-flux ezisetshenziswa ku-electronics soldering, nokuthi yini okufanele uyicabangele ngaphambi kokusebenzisa enye yazo ngokwakho.
Kulokhu okuthunyelwe sizomboza:
- Kungani kudingeka i-flux ku-electronics soldering?s Flux Iyadingeka ku-Electronics Soldering
- I-Oxidation: Ingabe kuyinto embi?
- Ukusetshenziswa kwe-flux ukususa i-oxidation
- Izinhlobo ezahlukene ze-flux ku-soldering ye-elekthronikhi
- Uhlobo lokuguquguquka okufanele lugwenywe ekufakweni kwe-elekthronikhi: I-Inorganic acid flux
- Sebenzisa uhlobo olufanele lokuguquguquka komsebenzi
Kungani kudingeka i-flux ku-electronics soldering?s Flux Iyadingeka ku-Electronics Soldering
Ngenkathi uzama ukugcwalisa indawo yokuhlanganisa yezinsimbi ezi-2 ngenye insimbi (okuyinto empeleni e-soldering), ukungcola kanye nemfucumfucu kulezo zindawo zensimbi kuvimbela ukwakhiwa kokuhlangana okuhle. Ungasusa futhi uhlanze ukungcola okunga-oxidizing kulezo zindawo kalula, kodwa kufanele usebenzise i-flux uma uzama ukususa i-oxidation.
I-Oxidation: Ingabe kuyinto embi?
I-oxidation yinto engokwemvelo. Kodwa lokho akusho ukuthi konke kuhle.
Zonke izinsimbi ziphendulana nomoya-mpilo osemoyeni nasezixubeni zamakhemikhali eziyinkimbinkimbi endaweni yensimbi okunzima ukuyikhipha futhi okwenza kube nzima kakhulu ukudayiswa. Ukuxhuma kuvame ukubizwa ngokuthi ukugqwala ensimbi.
Ukusetshenziswa kwe-flux ukususa i-oxidation
I-Flux enye inhlanganisela yamakhemikhali esabela nge-oxidation, ngaphansi kwezinga lokushisa eliphezulu, ukuncibilika, nokukhipha i-oxidation. Udinga njalo sebenzisa ukugeleza ukuhlanza i-oxidation ethiphu lakho le-soldering iron ngoba amazinga okushisa aphezulu ayayisheshisa.
Gcina lokhu engqondweni uma uhlosile ukwenza insimbi yakho ye-soldering.
Izinhlobo ezahlukene ze-flux ku-soldering ye-elekthronikhi
I-flux esetshenziswa kumabhodi esekethe kagesi ayilona uhlobo olufanayo nalawo asetshenziswa ezintanjeni njengoba adinga izakhiwo ezihlukile kusuka ku-flux.
Ngezansi, ngizokutshela ngazo zonke izinhlobo ze-flux ezitholakalayo emakethe ye-electronics soldering.
Ukuhamba kwe-Rosin
Ukushaya zonke ezinye izinto eziguquguqukayo ngokweminyaka i-rosin flux.
Ezinsukwini zokuqala zokukhiqiza, ama-rosin fluxes ayenziwa kusuka ku-pine sap. Ngemuva kokuthi ubisi seluqoqiwe, liyacwengwa futhi lihlanzwe libe yi-rosin flux.
Kodwa-ke, kulezi zinsuku, amanye amakhemikhali ahlukene kanye nokuguquguquka kuhlanganiswa ne-pine sap ecolisisiwe ukuze kukhiqizwe i-rosin flux.
I-rosin flux iphenduka ibe i-asidi ewuketshezi futhi igeleza kalula uma ishiswa. Kodwa lapho ipholisa, iba qinile futhi ine-inert.
Isebenza kahle kakhulu ekukhipheni i-oxidation ezinsimbi. Ngemuva kokuyisebenzisa kumasekhethi, ungayishiya isesimweni sayo esiqinile, esingasebenzi. Ngeke isabele nanoma yini enye ngaphandle uma isishise ngokwanele ukuthi iguquke ibe yi-asidi.
Uma ufuna ukususa izinsalela ngemuva kokusebenzisa i-rosin flux, udinga ukusebenzisa utshwala, njengoba bungancibiliki emanzini. Yingakho kufanele usebenzise utshwala esikhundleni samanzi angenalutho.
Kodwa akukho monakalo ekushiyeni izinsalela njengoba zinjalo, ngaphandle uma ufisa ukwenza umsebenzi ohlakaniphile wokugcina ibhodi lakho lesifunda lihlanzekile.
I-asidi ye-organic
Ama-asidi e-Organic afana ne-citric acid, i-lactic acid, ne-stearic acid asetshenziselwa ukudala lolu hlobo lokuguquguquka. Imvelo ebuthakathaka yalawa ma-asidi, ehlanganiswe ne-isopropyl alcohol namanzi, yakha ama-organic acid fluxes.
Inzuzo enkulu ye-organic acid fluxes ukuthi ayincibiliki ngokuphelele emanzini, ngokungafani ne-rosin flux.
Ngaphezu kwalokho, njengoba impahla ene-asidi ye-organic acid fluxes iphakeme kune-rosin fluxes, inamandla. Ngenxa yalokho, bangakwazi ukuhlanza ama-oxide ezindaweni zensimbi ngokushesha okukhulu.
Hlanganisa lawa mandla okukhipha i-oxidation nesimo sawo sokuncibilika, futhi unensalela eguquguqukayo okulula ukuyihlanza. Abukho utshwala obudingekayo!
Noma kunjalo, le nzuzo yokuhlanza iza ngezindleko. Ulahlekelwa yimpahla engelona i-conductivity yensalela ye-rosin flux njengoba ihambisa ngogesi futhi ingathinta ukusebenza kanye nokusebenza kwesekhethi.
Ngakho-ke qiniseka ukuthi ususa izinsalela ze-flux ngemuva kokuhlanganisa.
Ukugeleza okungahlanzekile
Njengoba nje igama liphakamisa, awudingi ukuhlanza izinsalela kulolu hlobo lokuguquguquka. Idala inani elincane kakhulu uma liqhathaniswa namanye ama-fluxes angu-2.
I-No-clean flux isekelwe kuma-asidi e-organic namanye amakhemikhali. Lezi zivame ukuza ngemijovo ukuze kube lula.
Kumasekhethi asebenzisa ubuchwepheshe be-surface-mount, kungcono ukusebenzisa lolu hlobo lwe-flux.
Futhi, i-ball grid array wuhlobo lwebhodi elibekwe phezulu elihlomula kakhulu ngokushintshashintsha okungahlanzekile. Inani elincane lezinsalela elizikhiqizayo alikwazi ukwenza noma ukugqwala. Ungawasebenzisa emabhodini okunzima ukuwafinyelela ngemva kokufakwa.
Kodwa-ke, abanye abasebenzisi bathola inani elikhulu ngokumangalisayo lensalela okunzima ukuyisusa, ngaphandle kokuthi i-conductive.
Qaphela lapho usebenzisa lezi zinguquko kumabhodi e-analog ane-impedance ephezulu. Sincoma ukuthi wenze olunye uphenyo ngaphambi kokusebenzisa i-no-clean flux ohlela ukuyisebenzisa.
Uhlobo lokuguquguquka okufanele lugwenywe ekufakweni kwe-elekthronikhi: I-Inorganic acid flux
I-Inorganic acid fluxes ikhiqizwa ngengxube yama-asidi aqinile afaka (kodwa angagcini nje) ku-hydrochloric acid.
Kufanele ugweme ukuguquguquka kwe-inorganic kumasekhethi nanoma yiziphi ezinye izingxenye ze-elekthronikhi, njengoba kokubili ukugeleza nezinsalela zakho kungase kudle. Enzelwe izinsimbi ezinamandla, hhayi izingxenye ze-electronic.
Bheka ividiyo ye-SDG Electronics yabasebenzisi be-YouTube esezingeni elingcono kakhulu lokudayiswa:
Sebenzisa uhlobo olufanele lokuguquguquka komsebenzi
Njengoba ubona, zonke izinhlobo zokuguquguquka zinezinzuzo kanye nokubi uma kukhulunywa ngakho usebenzisa i-flux ukuze uhlanganise. Manje unebanga ongakhetha kulo ngenkathi wenza umsebenzi wakho wokuhlanganisa izinto zikagesi.
Akekho ongamemezela noma iyiphi yalezo zinkimbinkimbi njengengcono kakhulu, njengoba imisebenzi ehlukene izodinga ukushintshashintsha okuhlukile.
Uma usebenza kumasekhethi asebenzisa ubuchwepheshe bokukhweza phezulu, ukubheja kwakho okuhle kungaba ukuguquguquka okungahlanzekile. Kodwa qaphela into eyengeziwe eyinsalela.
Futhi kwezinye izifunda, ungakhetha noma yini phakathi kwe-organic acid flux ne-rosin flux. Bobabili benza umsebenzi omuhle kakhulu!
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.
