Kuchengeta nzvimbo yemabasa ako yakachena kana iwe uchiyedza solder kwakakosha sekuchengeta rezinesi ndiro pamota yako. Uye ini handisi ari mudiki anotsvinya, bhiri rako razvino richakwira mudenga kune yakatadza kutengesa. Kana usiri kushandisa flux kuchenesa nzvimbo dzako iyo iyo soldering ichauya usati waiziva.
Kunze kwezvo, simbi inopisa inowanzo gadzira oxides kana yasangana nemhepo. Izvo zvinoita kuti iyo solder ikundikane yakawanda yenguva. Mazuva ano kune akati wandei akasiyana marudzi esoder kunze uko. Ngatitaurei nezvavo.
Mune ino posvo isu tichafukidza:
Mhando dzeSoldering Flux
Soldering fluxes anosiyana zvakanyanya maererano nemaitiro avo, simba, kukanganisa pane soldering quality, kuvimbika, nezvimwe. Nekuda kweizvi, haugone kushandisa chero flux mumiririri kune solder waya kana zvemagetsi zvikamu. Zvichienderana nebasa ravo rekuyerera, solder flux inowira muzvikamu zvinotevera:
Rosin nekubudisa
Pane mhando dzakasiyana dzekuyerera kwekugadzira magetsi, rosin flux ndeimwe yevakakurumbira vavo. Chinhu chekutanga mu rosin flux irosin iyo inotorwa kubva pakanatswa pinesap. Zvimwe kunze kweizvozvo, ine chinhu chinoshanda cheabietic acid pamwe neashoma chaiwo maasidhi. Mazhinji marosi flux ane ma activator mavari ayo anoita kuti kuyerera kuyeredze uye kuchenesa nzvimbo dzakatengeswa. Rudzi urwu runogona kuganhurwa muzvikamu zvidiki zvitatu:
Rosin (R) Flux
Iyi rosin (R) inoyerera inongowanikwa chete neine rosin uye isingashande pakati pemhando nhatu. Inonyanya kushandiswa pakutengesa tambo yemhangura, maPCB, uye mamwe mawoko-ekunamatira ruoko. Kazhinji, inoshandiswa pane yakatocheneswa nzvimbo ine hushoma oxidation. Kubatsira kukuru kwacho hakusi kusiya chero masara kumashure.
Rosin Zvinyoro Anoshanda (RMA)
Rosin zvinyoro-kusashanda kuyerera kune zvakakwana activators kuchenesa zvine mwero yakasviba nzvimbo. Nekudaro, zvigadzirwa zvakadaro zvinosiya zvakasara kupfuura chero imwe yakajairika kuyerera. Nekudaro, mushure mekushandisa, iwe unofanirwa kuchenesa nzvimbo ne flux cleaner kudzivirira chero kukuvara kune dunhu kana zvikamu.
Rosin Yakagadzirwa (RA)
Rosin yakamisikidzwa ndiyo inonyanya kushanda pakati pemhando nhatu dzerosin flux. Iyo inochenesa yakanakisa uye inopa yakanakisa kugadzira. Izvi zvinoita kuti zvive zvakanaka pakuchenesa zvakaoma kuchenesa huso hune huwandu hwakawanda hwe oxides huripo. Parutivi rweflip, urwu rudzi haruwanzoshandiswa sezvo ruchiwanzosiya huwandu hwakawanda hwemasara kumashure.
Mvura Soluble Flux kana Organic Acid Flux
Rudzi urwu runonyanya kushomeka isina kusimba organic acids uye inonyungudika nyore mumvura uye isopropyl doro. Nekudaro, iwe unogona kubvisa flux masara uchishandisa chete akajairwa mvura. Asi iwe unofanirwa kutarisira kuti izvo zvikamu hazvinyoro.
Pamusoro pezvo, rudzi urwu rune simba rinokuvadza kupfuura rosin-based fluxes. Nekuda kweizvi, ivo vari kukurumidza nzira pakubvisa oxides pamusoro. Zvisinei, iwe unozoda kumwe kudzivirirwa panguva yekuchenesa pcb kudzivirira huturu kusvibiswa. Zvakare, mushure mekunamatira, zvisaririra zvemvura yakasara inofanira kucheneswa.
Isina kujairika Acid Flux
Inorganic acid fluxes inoitirwa iyo yakanyanya-tembiricha soldering iyo yakaoma kusunga. Izvi zvinowedzera kupisa kana kusimba kupfuura organic fluxes. Kunze kwezvo, anoshandiswa pane simbi dzakasimba uye anobatsira kubvisa huwandu hwakawanda hwe oxides kubva kune dzakanyanya oxidized simbi. Asi, izvi hazvina kukodzera zvakanyanya kumagungano emagetsi.
Kwete-Yakachena Flux
Kune yerudzi urwu rwekuyerera, kuchenesa hakudiwe mushure mekunamatira. Iyo yakanyatsogadzirirwa kuve neyakareruka chiito. Nekudaro kunyangwe paine zvasara zvishoma zvasara, hazvingakonzere chero kukuvara kune izvo zvikamu kana mabhodhi. Nezvikonzero izvi, izvi zvakakosha kune otomatiki sarering zvikumbiro, wave soldering, uye pamusoro pegomo maPCB.
Yekutanga Gwaro | Mashandisiro Ekushandisa Flux yekuSoldering
Sezvauri kuona kune akawanda dzakasiyana marudzi ekubuda kwemagetsi emagetsi inowanikwa mumhando dzakasiyana-siyana senge mvura kana kunama. Zvakare, kune akasiyana soldering maitiro flux anoshandiswa zvakasiyana. Naizvozvo, kuti zvive nyore uye kudzivirira kuvhiringidzika, pano tinoenda kune nhanho-nhanho gwara rekushandisa soldering flux.
Sarudza Inokodzera Flux uye Gadzira iyo Surface
Pakutanga, sarudza inoyerera yakakodzera yebasa rako rekumisikidza kubva kune runyorwa rwemhando dzakasiyana dzemhando inochinja. Tevere, iwe unofanirwa kuchenesa iyo yesimbi pamusoro kuti irege kuva neguruva, kutyisa, kana kunyanyisa oxidation.
Vhara iyo Nharaunda neFlux
Mushure meizvozvo, iwe unofanirwa kuisa kunyange yakaturikidzana yeiyo yakasarudzika kuyerera kumusoro uko kwauchange uri kuteta. Ziva kuti iwe unofanirwa kufukidza zvizere nzvimbo yacho. Panguva ino, haufanire kuisa kupisa.
Nyorera Kupisa neSoldering Iron
Tevere, tanga iyo simbi kuitira kuti tip yacho ipise zvakakwana kuti inyungudise kubuda nekubatana. Isa simbi pamusoro penzizi uye ibvumire kuti inyungudise kuyerera kune fomu remvura. Izvi hazvingobatsire chete kubvisa izvozvi oxide dura, asi zvakare zvinodzivirira ramangwana oxidization kusvika iko kuyerera kwasara. Zvino, iwe unogona kutanga iyo soldering maitiro.
Soldering Wires ine Soldering Flux
Kushandisa soldering flux nepo waya waya kana zvinongedzo zvine mashoma misiyano kubva pane yakajairika maitiro atakatsanangura kare. Sezvo izvi zvinyoro nyoro, shanduko shoma dzinogona kukanganisa waya. Ichi chikonzero, usati washandisa kuyerera pane waya, ita shuwa kuti urikuita nenzira kwayo.
Sarudza Kurudyi Flux
Sezvo waya zhinji dzisina kusimba uye dzakaonda, kushandisa chero chinhu chinokanganisa kunogona kukuvadza dunhu rako. Nekudaro, nyanzvi zhinji dzinokurudzira kutora rosin-based flux yekunamatira nekuti ndiyo isinganetsi.
Chenesa uye Simbisa iyo waya
Kunyanya ita shuwa kuti waya yega yega yakachena. Iye zvino, shandura magumo akafumurwa etambo yega yega pamwechete. Ramba uchimonyorora waya kumusoro nekukomberedza kusvikira iwe usingaone chero akanongedzwa magumo. Uye kana iwe uchida kuisa kupisa-kunyura tubing pamusoro peiyo yako soldering, ita izvi usati wamonyorora waya. Ita shuwa kuti tubing idiki uye inodzikira zvine simba kune waya.
Isa Soldering Flux paMatare
Kupfeka tambo, shandisa minwe yako kana bhurasho rependi kuti utore huwandu hwekuyerera uye uvaparidze pamusoro penzvimbo. Flux inofanira kuvhara zvizere waya. Pasina kutaura, iwe unofanirwa kupukuta yakawandisa flux usati watanga kusodera.
Sungunusa iyo Flux ine Soldering Iron
Pisa simbi izvozvi uye kana zvangopisa, pinda simbi kune rimwe divi redambo. Ramba uchiita izvi kudzamara kuyerera kwakanyungudika uye kwatanga kubhowa. Iwe unogona kuisa shoma shoma pasoda padivi resimbi uchisundidzira iyo kune waya kuti ikurumidze kupisa kupisa.
Nyorera Solder muMatare
Ipo iyo simbi yakadzvanywa ichipesana newaya padivi repazasi, isa mamwe solder kupinda rimwe divi rewaya. Iyo solder inonyungudika ipapo kana iyo simbi ichipisa zvakakwana. Ive neshuwa kuti iwe uchaisa yakakwana solder yekuvhara iyo kubatana zvachose.
Regai Solder Harden
Ikozvino tora iyo yesimbi simbi uende nayo uye iva nemoyo murefu kuti iyo solder itonhorere pasi. Sezvo pavanotonhora iwe unogona kuvaona vachiomesa. Kamwe iyo solder yaiswa, tsvaga chero yakafumurwa waya. Kana paine chero, fudza imwezve solder mairi uye rega iome.
mhedziso
Kugadzira hunyanzvi kuri nyore, asi chikanganiso chidiki chinogona kunge chiri munzira yekugadzira chisungo chakakwana. Nekudaro, zvinonyanya kudikanwa kuti uzive mashandisirwo akakodzera eSoldering flux. Kunyangwe iwe uri wekutanga kana asiri-wehunyanzvi, netarisiro, gwara redu rakadzama rakakubatsira iwe zvakakwana kuti unzwisise zvizere zvese zvakakosha zvekuishandisa.
Ramba uchifunga kuti soldering flux inokuvadza uye inogona kukuvadza ganda rako kana iri muchimiro chemvura kana kupisa. Asi iwe haufanire kunetseka kana iine pasty dhizaini. Nekuwedzera kuchengetedzeka, shandisa magasi anopisa-anopisa paunenge uchishanda.
