Yebo. Insimbi engagqwali engu-304 ingadayiswa ngempumelelo ekhopha ku-vacuum kusetshenziswa izinhlobo ezahlukahlukene nezithasiselo ze-chemical soldering (BFM). Izinsimbi zokugcwalisa ezisekelwe kugolide, isiliva ne-nickel zingasebenza. Njengoba ithusi likhula kancane kune-304 insimbi engagqwali, ukunakwa okukhethekile kufanele kukhokhwe ekucushweni kokuxhuma. Kulokhu, amandla ethusi azoba aphansi kakhulu, ngakho-ke angakwazi ukufaka insimbi engagqwali ngaphandle kokuguqulwa okubonakalayo.
Ama-brazed assemblies ngokuvamile asetshenziswa emazingeni okushisa afika ku-4° Kelvin. Kukhona ukucatshangelwa kokuklama kanye nemikhawulo, kodwa izinsimbi zokugcwalisa ezisekelwe egolide nezesiliva zivame ukusetshenziselwa lolu hlelo lokusebenza.
3. Ngidinga ukuthengisa umhlangano oyinkimbinkimbi, kodwa angazi ukuthi ngingathengisa kanjani yonke into ngesikhathi esisodwa. Ingabe i-multi-step soldering yezingxenye kungenzeka?
Yebo! Umhlinzeki we-solder ochwepheshe angahlela inqubo ye-solder yezinyathelo eziningi. Cabanga ngezinto eziyisisekelo kanye ne-BFM ukuze i-solder yasekuqaleni ingancibiliki ekugijimeni okulandelayo. Ngokuvamile, umjikelezo wokuqala ugijima ezingeni lokushisa eliphezulu kunemijikelezo elandelayo futhi i-BFM ayibuyiseli emijikelezweni elandelayo. Kwesinye isikhathi i-BFM isebenza kakhulu ekusabalaliseni izithako ku-substrate kangangokuthi ukubuyela ezingeni lokushisa elifanayo kungase kungabangeli ukuncibilika. I-Multi-step soldering ingaba ithuluzi elilula nelisebenza kahle lokukhiqiza izingxenye zezokwelapha ezibizayo.
Le nkinga ingaxazululeka! Kunezindlela zokuvimbela lokhu, indlela ephumelela kakhulu ukusebenzisa inani elifanele le-BFM. Uma i-joint incane futhi incane endaweni, kungase kubonakale kumangala ukuthi ingakanani i-BFM edingekayo ukuze kuthengiswe kahle ukujoyina. Bala indawo eyi-cubic yejoyinti bese uzama ukusebenzisa i-BFM ethe ukudlula indawo ebaliwe. Idizayini yokufaka ipulaki iyisokhethi enesithukuthezi, efana nobubanzi bangaphakathi beshubhu, okuvumela i-BFM ukuthi ihambe ngokuqondile kububanzi bangaphakathi beshubhu ngesenzo se-capillary. Shiya indawo ekupheleni kweshubhu ukuze uvimbele ukusebenza kwe-capillary, noma uklame uxhumano ukuze ishubhu ikwazi ukuphuma kancane ngaphesheya kwendawo yokuxhuma. Lezi zindlela zakha indlela enzima kakhulu yokuthi i-BFM ihambe iye ekupheleni kwepayipi, ngaleyo ndlela inciphise ingozi yokuvala.
Lesi sihloko siphuma ngezikhathi ezithile futhi sidinga ukudingidwa. Ngokungafani nezibopho ze-solder, ezidala amandla ekuhlanganyeleni, izibopho ezinkulu ze-solder azichithi i-BFM futhi zingaba yingozi. Okubalulekile yilokho okungaphakathi. Amanye ama-PM ashwabene ezinhlamvini ezinkulu ngenxa yokugxila kwezingxenye zamaphuzu ancibilikayo angahlukanisi. Kulesi simo, ngisho nokukhathala okuncane, i-fillet ingaqhekeka futhi ikhule ibe ukwehluleka okuyinhlekelele. Lapho i-soldering, ubuncane, ubukhona obuqhubekayo be-BFM kusixhumi esibonakalayo esihlanganyelwe kuvame ukuba umbandela ofaneleka kakhulu wokuhlola okubukwayo.
