Kuwotcha kwazitsulo zamkuwa ndi zamkuwa

1. Kuwotcha zinthu

(1) Mphamvu yomangirira ya ma solders angapo omwe amagwiritsidwa ntchito kwambiri powotcha mkuwa ndi mkuwa akuwonetsedwa patebulo 10.

Table 10 mphamvu yamkuwa ndi mkuwa brazed mfundo

Mukawotcha mkuwa ndi tin lead solder, kusungunuka kwamadzi osawononga monga rosin alcohol solution kapena active rosin ndi zncl2+nh4cl aqueous solution kungasankhidwe.Zomalizazi zitha kugwiritsidwanso ntchito popanga mkuwa, mkuwa ndi mkuwa wa beryllium.Mukawotcha mkuwa wa aluminiyamu, mkuwa wa aluminiyamu ndi mkuwa wa silicon, kutulutsa kwake kumatha kukhala yankho la zinc chloride hydrochloric acid.Mukawotcha mkuwa woyera wa manganese, jekeseni akhoza kukhala phosphoric acid yankho.Zinc chloride aqueous solution itha kugwiritsidwa ntchito ngati flux poyaka ndi chitsulo chodzaza ndi lead, ndipo fs205 flux itha kugwiritsidwa ntchito poyaka ndi cadmium based filler chitsulo.

(2) Mukawotcha mkuwa ndi zitsulo zodzaza ndi brazing ndi ma fluxes, zitsulo zokhala ndi siliva ndi zitsulo zamkuwa za phosphorous zitha kugwiritsidwa ntchito.Silver based solder ndiyo yogwiritsidwa ntchito kwambiri molimbika chifukwa cha kusungunuka kwake kocheperako, kukhazikika bwino, makina abwino amakina, magetsi ndi matenthedwe matenthedwe.Pazogwirira ntchito zomwe zimafunikira ma conductivity apamwamba, solder ya b-ag70cuzn yokhala ndi siliva wambiri imasankhidwa.Pakuwotcha kwa vacuum kapena kuyatsa mu ng'anjo yoteteza, b-ag50cu, b-ag60cusn ndi zida zina zowotchera zopanda zinthu zosasunthika zidzasankhidwa.Zitsulo zodzaza ndi brazing zokhala ndi siliva wotsika ndizotsika mtengo, zimakhala ndi kutentha kwakukulu komanso kusalimba kwa malo olumikizirana.Amagwiritsidwa ntchito makamaka pakuwotcha ma aloyi amkuwa ndi amkuwa okhala ndi zofunikira zochepa.Mkuwa wa phosphorous ndi mkuwa wa phosphorous siliva brazing filler zitsulo zingagwiritsidwe ntchito pomanga mkuwa ndi ma aloyi ake amkuwa.Pakati pawo, b-cu93p ili ndi madzi abwino ndipo imagwiritsidwa ntchito popanga zida zomwe sizimakhudzidwa ndi kuchuluka kwa Electromechanical, zida ndi mafakitale opanga.Kusiyana koyenera kwambiri ndi 0.003 ~ 0.005mm.Zitsulo zamkuwa za phosphorous brazing filler (monga b-cu70pag) zimakhala ndi kulimba komanso kuwongolera bwino kuposa zitsulo zamkuwa za phosphorous brazing.Amagwiritsidwa ntchito makamaka pamalumikizidwe amagetsi omwe ali ndi zofunika kwambiri za conductivity.Gome 11 likuwonetsa zida zomwe zimagwiritsidwa ntchito popangira mkuwa ndi mkuwa.
