Insimbi engagqwali engu-304 ingadayiswa ngempumelelo ekhopha ku-vacuum kusetshenziswa izinhlobo ezihlukahlukene 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-solder ahlanganisiwe ngokuvamile asetshenziswa emazingeni okushisa afika ku-4° Kelvin.Kukhona ukucatshangelwa kokuklama kanye nemikhawulo, kodwa izinsimbi zokugcwalisa ezisekelwe egolide nezesiliva zivame ukusetshenziselwa lolu hlelo lokusebenza.
Ngidinga ukudayisa 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 yelunga bese uzama ukusebenzisa i-BFM ethe ukudlula indawo ebaliwe.Idizayini efakekayo exhunywayo iyisokhethi enesithukuthezi efana ne-ID yeshubhu, evumela i-BFM ukuthi ihambe iqonde ku-ID yeshubhu ngesenzo se-capillary.Shiya indawo ekupheleni kweshubhu ukuze uvimbele ukusebenza kwe-capillary, noma uklame ilunga ukuze ishubhu liphumele ngaphandle kancane endaweni ehlangene.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.
