Ehe.304 simbi isina tsvina inogona kunyatsotengeswa kumhangura mune vacuum uchishandisa akasiyana marudzi uye makemikari soldering additives (BFM).Filler simbi dzakabva pagoridhe, sirivheri uye nickel dzinogona kushanda.Sezvo mhangura ichiwedzera zvishoma kupfuura 304 simbi isina tsvina, kutarisisa kwakakosha kunofanirwa kubhadharwa kune yekubatanidza gadziriso.Muchiitiko ichi, simba remhangura richave rakaderera zvikuru, saka rinogona kukodzera simbi isina tsvina pasina kuoneka deformation.
Magungano eBrazed anowanzo shandiswa patembiricha inosvika 4° Kelvin.Kune magadzirirwo ekufunga uye zvipimo, asi goridhe nesirivheri based filler masimbi anowanzo shandiswa pachishandiswa ichi.
3. Ndinofanira kutengesa gungano rakaoma, asi handizivi kuti ndingatengesa sei zvinhu zvose panguva imwe chete.Zvinogoneka here kuti multi-step soldering yezvikamu?
Ehe!Inyanzvi yekutengesa mutengesi inogona kuronga maitiro akawanda-nhanho soldering.Funga nezvechigadziko zvinhu uye BFM kuitira kuti yepakutanga solder joint irege kunyunguduka mukumhanya kunotevera.Kazhinji, kutenderera kwekutanga kunomhanya pane tembiricha yakakwira kupfuura kutenderera kunotevera uye iyo BFM haidzokeri mumatanho anotevera.Dzimwe nguva BFM inoshanda zvakanyanya mukuparadzanisa zvinongedzo mu substrate zvekuti kudzoka kune imwe tembiricha inogona kusakonzeresa kunyungudika.Multi-step soldering inogona kuve iri nyore uye inoshanda chishandiso chekugadzirwa kwezvinhu zvinodhura zvekurapa.
Dambudziko iri rinogona kugadziriswa!Pane nzira dzekudzivirira izvi, nzira inonyanya kushanda ndeye kushandisa huwandu hwakakodzera hweBFM.Kana iyo yakabatana iri diki uye diki munzvimbo, zvingaite senge zvichishamisa kuti yakawanda sei BFM inodiwa kuti inyatso solder mubatanidzwa.Verenga iyo cubic nzvimbo yejoint uye edza kushandisa zvishoma BFM kupfuura iyo yakaverengerwa nzvimbo.Dhizaini yekugonesa pluggable socket yakabhowa, yakafanana neyemukati dhayamita yechubhu, iyo inobvumira iyo BFM kufamba yakananga kudhayamita yemukati yechubhu ne capillary action.Siya nzvimbo pamagumo echubhu kudzivirira capillary chiito, kana kugadzira chinongedzo kuitira kuti tubing ibude zvishoma kupfuura nzvimbo yekubatanidza.Idzi nzira dzinogadzira nzira yakaoma yeBFM kufamba kusvika kumagumo epombi, nokudaro kuderedza dambudziko rekuvhara.
Musoro uyu unouya nguva nenguva uye unoda kukurukurwa.Kusiyana nemafuta ekutengesa, ayo anogadzira simba mumubatanidzwa, mafiritsi makuru e solder haaparadze BFM uye anogona kukuvadza.Chinokosha ndezvipi zviri mukati.Mamwe maPM ane brittle muhombe fillet nekuda kwekusangana kwezvisiri-diffusing low melting point components.Muchiitiko ichi, kunyange nekuneta kwakadzikama, fillet inogona kutsemuka uye kukura kusvika pakukundikana kukuru.Paunenge uchitengesa, hushoma, hunogara huripo hweBFM pajoint interface kazhinji ndiyo inonyanya kukodzera yekuongorora kwekuona.
