Soldering inzira yekubatanidza simbi mbiri kune imwe neimwe kune yakasimba uye yakasimba joint. Izvi zvinoitwa nekushandisa filler metal.
Iyi nzira yekubatanidza simbi kune imwe inoshandiswa zvakanyanya mumagetsi. Plumbing uye metalworks zvakare ane kushandiswa kwakakura kwehunyanzvi uhu.
Zvichienderana nenyaya, marudzi akasiyana e zvinoyerera dzinoshandiswa. Electronics soldering inzvimbo ine hunyanzvi uko iyo flux inoshandiswa inofanirwa kuve nehumwe hunhu, senge isiri-conductivity.
Muchikamu chino, ini ndichakuudza nezve mhando dze flux dzinoshandiswa mumagetsi soldering, uye zvaunofanira kufunga nezvazvo usati washandisa imwe yadzo iwe pachako.
Mune ino posvo isu tichafukidza:
- Sei flux ichidikanwa mumagetsi soldering? Flux Inodiwa muElectroniki Soldering
- Oxidation: Chinhu chakaipa here?
- Kushandisa flux kubvisa oxidation
- Mhando dzakasiyana dzekuyerera mumagetsi solder
- Rudzi rwekuyerera kudzivirira mune zvemagetsi solder: Inorganic acid flux
- Shandisa iyo chaiyo mhando yekuyerera yebasa racho
Sei flux ichidikanwa mumagetsi soldering? Flux Inodiwa muElectroniki Soldering
Paunenge uchiedza kuzadza chinongedzo chesimbi mbiri neimwe simbi (iyo inonyanya kutengeswa), tsvina nemarara pane izvo zvesimbi zvinokanganisa kusikwa kwekubatana kwakanaka. Iwe unogona kubvisa uye kuchenesa iyo isiri-oxidizing tsvina kubva kune iyo nzvimbo zviri nyore, asi iwe unofanirwa kushandisa flux paunenge uchiedza kubvisa oxidation.
Oxidation: Chinhu chakaipa here?
Oxidation chinhu chepanyama. Asi hazvirevi kuti zvose zvakanaka.
Masimbi ese anopindirana neokisijeni iri mumhepo uye kubva kumakemikari akaomarara ari pamusoro pesimbi yakaoma kubvisa uye inoita kuti zviome kwazvo kutengeswa. Kuvharidzira kunowanzonzi ngura pane iron.
Kushandisa flux kubvisa oxidation
Flux imwezve kemikari inopindirana neoxidation, pasi pekushisa kwakanyanya, kunyungudika, uye kubvisa oxidation. Unofanira kuita kakawanda shandisa kuyerera kuchenesa oxidation kubva kune yako solder iron tip nekuti tembiricha yakakwira inomhanyisa.
Ramba uchifunga izvi kana iwe uchida kuti uite yako wega simbi simbi.
Mhando dzakasiyana dzekuyerera mumagetsi solder
Iyo inoyerera iyo inoshandiswa pamabhodhi emagetsi emagetsi haisi iyo yakafanana neiyo inoshandiswa pawaya sezvo ichida zvivakwa zvakasiyana kubva pakuyerera.
Pazasi, ini ndichakuudza nezve ese marudzi e flux anowanikwa pamusika wemagetsi solder.
Rosin nekubuda
Kurova mamwe ese anoyerera maererano nezera iri rosin flux.
Mumazuva ekutanga ekugadzirwa, rosin fluxes yakagadzirwa kubva papine sap. Mushure mekunge muto waunganidzwa, unonatswa uye unonatswa kuita rosin flux.
Nekudaro, mazuva ano, mamwe makemikari akasiyana uye fluxes anosanganiswa neyakacheneswa pine sap kuburitsa rosin flux.
Rosin flux inoshanduka kuita mvura asidhi uye inoyerera zviri nyore kana yapiswa. Asi pakutonhora, inova yakasimba uye inert.
Inoshanda zvakanyanya mukubvisa oxidation kubva musimbi. Mushure mekuishandisa pamaseketi, unogona kuisiya iri yakasimba, inert state. Izvo hazvizoite nechimwe chinhu kunze kwekunge chadziya zvakakwana kuti chishanduke kuita acid.
Kana iwe uchida kubvisa zvakasara mushure mekushandisa rosin flux, unoda kushandisa doro, sezvo isiri mvura inonyunguduka. Ndicho chikonzero iwe unofanirwa kushandisa doro panzvimbo yemvura yakachena.
Asi hapana chakaipa pakusiya zvakasara sezvazviri, kunze kwekunge uchishuvira kuita basa rekuchenjera rekuchengeta bhodhi rako redunhu rakachena.
Organic acid inoyerera
Organic acids se citric acid, lactic acid, uye stearic acids inoshandiswa kugadzira rudzi urwu rwekuyerera. Hunhu husina kusimba hweaya asidhi, yakasanganiswa neisopropyl doro nemvura, inoumba organic acid inoyerera.
Mukana mukuru we organic acid fluxes ndeyekuti iwo anonyatsonyungudika mumvura, kusiyana nerosin flux.
Pamusoro pazvo, sezvo iyo acidic pfuma yeorganic acid inoyerera ichikwira kupfuura rosin fluxes, iwo akasimba. Nekuda kweizvozvo, vanogona kuchenesa maokisi kubva pasimbi pepamusoro nekukurumidza.
Bata iyi oxidation yekubvisa simba nehunhu hwayo hwekunyungudika, uye iwe une nyore-ku-kuchenesa-inoyerera yakasara. Hapana doro rinodiwa!
Zvakadaro, iyi bhenefiti yekuchenesa inouya nemubhadharo. Iwe unorasikirwa neiyo isiri-conductivity chivakwa cheiyo rosin flux yakasara sezvo ichiita zvemagetsi uye inogona kukanganisa kuita kwese uye kushanda kwedunhu.
Saka ita shuwa kuti unobvisa iyo flux yakasara mushure mekutengesa.
No-clean flux
Sezvinoreva zita, haufanire kuchenesa zvakasara kubva kurudzi urwu rwekuyerera. Inogadzira huwandu hudiki hwakanyanya uchienzaniswa nemamwe 2 fluxes.
Hapana-yakachena flux yakavakirwa pane organic acids uye mamwe mamwe makemikari. Aya kazhinji anouya mumajekiseni kuti zvive nyore.
Kune maseketi anoshandisa pamusoro-gomo tekinoroji, zviri nani kushandisa rudzi urwu rwekuyerera.
Zvakare, iyo bhora grid array imhando yepamusoro-yakamisikidzwa bhodhi iyo inobatsira zvakanyanya kubva isina-yakachena fluxes. Huwandu hudiki hwezvisaririra hwainoburitsa haubatike kana kukanganisa. Iwe unogona kuzvishandisa pamapuranga ayo akaoma kuwana mushure mekuiswa.
Nekudaro, vamwe vashandisi vanowana yakawandisa inokatyamadza yakawanda yasara iyo yakaoma kubvisa, kunze kwekuve conductive.
Ngwarira paunenge uchishandisa idzi fluxes pamapuranga analog ane high impedance. Isu tinokurudzira kuita kumwe kubvunza usati washandisa iyo isina-yakachena flux yauri kuronga kushandisa.
Rudzi rwekuyerera kudzivirira mune zvemagetsi solder: Inorganic acid flux
Inorganic acid fluxes inogadzirwa kubva musanganiswa weasidhi yakasimba inosanganisira (asi isina kugumira ku) hydrochloric acid.
Iwe unofanirwa kudzivirira inorganic flux pamaseketi kana chero zvimwe zvikamu zvemagetsi, sezvo zvese zvinoyerera uye zvakasara zvinogona kukanganisa. Izvo zvakagadzirirwa simbi yakasimba, kwete zvemagetsi.
Tarisa YouTube mushandisi SDG Electronics 'vhidhiyo pane yakanakisa flux ye soldering:
Shandisa iyo chaiyo mhando yekuyerera yebasa racho
Sezvaungaona, marudzi ese ekuyerera ane zvaakanakira uye zvazvakaipira kana zvasvika kushandisa flux ye soldering. Iwe zvino wava nemhando yekusarudza kubva paunenge uchiita basa rako rekutengesa pamagetsi.
Hapana anogona kuzivisa chero imwe yeaya mafashama seakanakisa kunze uko, sezvo akasiyana mabasa achada akasiyana fluxes.
Kana iwe ukashanda pamaseketi anoshandisa pamusoro-gomo tekinoroji, bheji yako yakanakisa ingave isina-yakachena flux. Asi chenjerera pamusoro pechimwe chinhu chakasara.
Uye kune mamwe maseketi, unogona kusarudza chero chinhu pakati peorganic acid flux uye rosin flux. Vose vari vaviri vanoita basa rakanaka!
Ini ndini Joost Nusselder, muvambi weZvishandiso Chiremba, mushambadzi wemukati, uye baba. Ini ndinoda kuyedza michina mitsva, uye pamwe nechikwata changu ndanga ndichigadzira zvakadzama blog zvinyorwa kubva 2016 kubatsira vaverengi vakavimbika nematurusi & matipi ekugadzira.
