Flux ikemikari inoshandiswa kuderedza kusawirirana kwesimbi kuti ibatsire mukusodha. Inoshandiswa kune zvese base simbi uye solder kubvisa okisidhi uye zvinosvibisa kubva panzvimbo kugadzira yunifomu yakanyoroveswa pamusoro.
Muchikamu chino, ini ndichatsanangura kuti flux chii, kuti inoshanda sei, uye nei yakakosha pakubudirira soldering. Uyezve, ini ndichagovera mamwe emhando dzakasiyana dziripo.
Mune ino posvo isu tichafukidza:
Flux: Iyo Isinganzwisisike Simba Inoita Kuti Soldering Igoneke
Flux chinhu chinoiswa panzvimbo dzesimbi isati yasonderwa kubatsira solder kuyerera nekusunga zvakanaka. Icho chinhu chakakosha mukuita solder, sezvo ichibatsira kubvisa chero oxide layers inogona kunge iripo pamusoro pesimbi, ichibvumira solder kunamira kune simbi.
Flux Inoshanda Sei?
Flux inoshanda nekudzikisa tension yepasi ye solder, ichibvumira kuti iyerere zviri nyore uye zvakaenzana pamusoro pesimbi. Inobatsirawo kudzivirira oxidation nekugadzira chipingamupinyi pakati pesimbi nemhepo.
Mhando dzeFlux
Kune akati wandei akasiyana emhando dzeflux aripo, imwe neimwe iine yayo yakasarudzika zvivakwa uye mashandisirwo. Mamwe emhando dzakajairika anosanganisira:
- Rosin flux: Iyi ndiyo inonyanya kuzivikanwa mhando yekuyerera uye inogadzirwa kubva kune resin yemiti yemipine. Iyo yakanaka-yechinangwa flux inoshanda nemazvo kune akawanda soldering application.
- Mvura-soluble flux: Iyi mhando yekuyerera iri nyore kuchenesa nemvura uye inowanzoshandiswa mukugadzira magetsi.
- Hapana-yakachena flux: Iyi mhando yekuyerera inosiya kuseri kushoma kwasara uye yakanakira maapplication uko kuchenesa kwakaoma kana kusingagoneke.
Sei Uchida Flux?
Flux yakakosha pakubudirira kwekutengesa nekuti inobatsira kuve nechokwadi chakasimba, chakavimbika chisungo pakati pemarata ari kubatanidzwa. Pasina flux, solder inogona kusayerera zvakanaka, zvichiita kuti pave nekubatana kusina simba kana kusavimbika.
Flux Inoshandiswa Sei?
Flux inogona kuiswa nenzira dzakasiyana siyana, zvichienderana nerudzi rwekuyerera uye mashandisiro. Dzimwe nzira dzakajairika dzinosanganisira:
- Brushing: Flux inogona kuiswa uchishandisa bhurashi diki kana applicator.
- Kupfapfaidza: Mamwe marudzi ekuyerera anogona kumwaya pamusoro pesimbi.
- Kunyudza: Simbi inogona kunyikwa mumudziyo wekuyerera.
Zvakajairika Zvikanganiso Paunenge Uchishandisa Flux
Nepo flux chiri chinhu chakakosha cheiyo soldering process, zviri nyore kuita zvikanganiso kana uchiishandisa. Zvimwe zvikanganiso zvinowanzoitika zvinosanganisira:
- Kushandisa yakawandisa flux: Izvi zvinogona kukonzera kukanganisa, kwakaoma-ku-kuchenesa mubatanidzwa.
- Kushandisa iyo isiriyo mhando yekuyerera: Kushandisa iyo isiriyo mhando yekuyerera kunogona kukonzera isina kusimba kana kusavimbika majoini.
- Kwete kuchenesa iyo inoyerera yakasara: Flux yakasara inogona kukanganisa uye inogona kukuvadza mubatanidzwa nekufamba kwenguva kana isina kunyatsocheneswa.
Kunzwisisa iyo Terminology yeFlux
Flux ishoko rinoshandiswa munzvimbo dzakasiyana siyana, kusanganisira electromagnetism, transport, uye Calculus. Izwi rokuti "flux" rinobva pashoko rechiLatini rokuti "fluxus," rinoreva "kuyerera." Muchidzidzo fundoyetsimba Iyo pfungwa yekuyerera yakakosha pakuongororwa kweakawanda masisitimu emuviri, uye yakabatsira mukuvandudza dzidziso huru mufizikisi.
Misiyano Yakakosha Mutsanangudzo yeFlux
Tsanangudzo yeflux inogona kusiyana zvichienderana nemunda waunoshandiswa. Heano mimwe misiyano yakakosha mukutsanangurwa kweflux:
- Muchidzidzo che electromagnetism, flux inoreva kubatanidzwa kwesimba remagineti pamusoro penzvimbo. Izvi zvinotsanangurwa naMaxwell's fundamental theorem ye electromagnetism.
- Mukufambisa, flux inotsanangura kufambiswa kwehuwandu, sehukuru kana simba, kuburikidza nepamusoro. Izvi zvinotsanangurwa neinoenderana density gradient.
- Muchiverengero (calculus), flux inobva papfungwa yezvinotorwa uye inoreva kushanduka kwehuwandu kuburikidza nepamusoro. Izvi zvinotsanangurwa ne gradient yebasa.
Iyo Seminal Contribution yaJames Clerk Maxwell
James Clerk Maxwell aive nyanzvi yefizikisi yekuScotland akapa mipiro kumunda we electromagnetism. Muchinyorwa chake "A Dynamical Theory of the Electromagnetic Field," akatsanangura pfungwa yekuyerera uye inotorwa mataurirwo ekubatanidzwa kwesimba remagineti pamusoro pepamusoro. Basa rake rakaisa hwaro hwekuvandudzwa kweiyo electromagnetic theory yemazuva ano.
Tsanangudzo Dzinopesana uye Kuchinjana kweMatemu
Tsanangudzo yekuyerera inogona kupokana uye kuchinjika zvichienderana nemunda waunoshandiswa. Semuenzaniso, mune zvisiri zvetekinoroji, mazwi ekuti "flux" uye "kuyerera" anowanzoshandiswa zvakasiyana kutsanangura zviitiko zvekongiri. Nekudaro, mune zvehunyanzvi mamiriro, mazwi ane tsananguro dzakasiyana uye haagone kushandiswa zvakasiyana.
Iko Kubatanidzwa kweFlux muCalculus
Mucalculus, flux inosanganiswa pamusoro pepamusoro kuti iwane mataurirwo ehuwandu hwekuchinja kwehuwandu. Izvi zvinoitwa uchishandisa theorem yakakosha yecalculus, iyo inotaura kuti kubatanidzwa kwebasa kwakaenzana nemusiyano pakati pehukoshi hwebasa pamagumo ekubatanidzwa. Iko kubatanidzwa kweiyo flux ipfungwa yakakosha mucalculus uye inoshandiswa mune akawanda maapplication, kusanganisira fluid dynamics uye kupisa kupisa.
Flux: Iyo Chakavanzika Ingredient ye Yakakwana Soldering
Flux ichemical agent inoshandiswa mukutengesa kusimudzira kunyorova kwesimbi nesolder yakanyungudutswa. Inobatsira kudzivirira kuumbwa kweoxides pamusoro pesimbi, iyo inogona kudzivisa kuyerera kwe solder uye kukonzera kusabatana kwakashata pakati pe solder nesimbi. Flux inodzivirirawo nzvimbo dzakafumurwa dzesimbi kubva kumhepo, izvo zvinogona kukonzera kuumbwa kwemafirimu eoxide, kushandura nzvimbo uye kuita kuti zviome kutengesa.
Chinangwa cheFlux muSoldering
Chinangwa chekuyerera mukutengesa ndechekubatsira mukugadzirwa kwenzvimbo yakanyoroveswa yakanyoroveswa pakati peiyo solder nesimbi inobatanidzwa. Flux inobatsira kuchenesa pamusoro pesimbi, kubvisa chero maokisi kana zvimwe zvinosvibisa zvinogona kudzivirira solder kunamatira zvakanaka. Iyo inosimudzirawo kuyerera kweiyo solder nekudzikisa tension yepasi yesolder yakanyungudutswa, ichibvumira kuti ipararire zviri nyore uye zvakafanana pamusoro penzvimbo dzesimbi.
Kusarudza Rudzi Rwakakodzera rweFlux kune Yako Soldering Maitiro
Kushandisa iyo chaiyo mhando yekuyerera kwakakosha kuti uve nechokwadi chekuita kwakanakisa kweako emagetsi zvikamu. Hezvino zvimwe zvikonzero nei:
- Kushandisa iyo isiriyo mhando yekuyerera kunogona kukonzera kushomeka kwekutengesa kuita uye kunyangwe kukuvadzwa kune ako majekiseni.
- Kushandisa iyo chaiyo mhando yekuyerera kunogona kuwedzera hupenyu hwezvikamu zvako uye kudzivirira kudiwa kwekugadzirisa kunodhura.
- Kushandisa iyo chaiyo mhando yekuyerera kunogona kuve nechokwadi chekuti yako soldering process inopedzwa nemazvo uye nemazvo.
Kuchenesa Flux Residue kubva kuElectronics
Paunenge wapedza kutengesa zvikamu zvako zvemagetsi, unogona kuona kuti pane imwe yakawandisa flux yasara pabhodhi. Kusiya izvi zvakasara pabhodhi zvinogona kukonzera matambudziko emagetsi uye kunyange mafupi mafupi. Naizvozvo, zvakakosha kuchenesa iyo inoyerera yakasara kubva kuPCB board yako kuti uvandudze huwandu hwese hwechigadzirwa chako.
mhedziso
Saka, ipapo iwe unayo- sumo pfupi yekuyerera uye nei ichikosha zvakanyanya paunenge uchitengesa. Flux inobatsira kubvisa oxide layers kubva musimbi uye inoita kuti solder ifambe zviri nyore. Icho chinhu chakakosha cheiyo soldering process uye inobatsira iwe kuti basa riitwe nemazvo. Saka, usakanganwa kuishandisa nguva inotevera paunenge uchishanda nesimbi.
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.
