Yebo. Insimbi engagqwali engu-304 ingashintshwa ibe yithusi endaweni yokuhlanza kusetshenziswa izinhlobo ezahlukene kanye nezithasiselo zokushiswa ngamakhemikhali (BFM). Izinsimbi zokugcwalisa ezisekelwe egolideni, esiliva nase-nickel zingasebenza. Njengoba ithusi landa kancane kunensimbi engagqwali engu-304, kufanele kuqashelwe ngokukhethekile ukucushwa kokuxhumana. Kulesi simo, amandla ethusi azoba aphansi kakhulu, ngakho-ke angangena ensimbi engagqwali ngaphandle kokuguquka okubonakalayo.
Izingxenye ze-solder zivame ukusebenza emazingeni okushisa afinyelela ku-4° Kelvin. Kunezindlela zokucabanga kanye nemikhawulo yokuklama, kodwa izinsimbi zokugcwalisa ezisekelwe egolideni nasesiliva zivame ukusetshenziswa kulolu hlelo lokusebenza.
3. Ngidinga ukusonta i-assembly eyinkimbinkimbi, kodwa angazi ukuthi ngingasonta kanjani konke ngesikhathi esisodwa. Ingabe kungenzeka ukusonta izingxenye ngezinyathelo eziningi?
Yebo! Umhlinzeki we-soldering ochwepheshe angahlela inqubo yokugoqa enezinyathelo eziningi. Cabanga ngezinto eziyisisekelo kanye ne-BFM ukuze i-solder joint yokuqala ingancibiliki ekugijimeni okulandelayo. Ngokuvamile, umjikelezo wokuqala usebenza ekushiseni okuphezulu kunemijikelezo elandelayo futhi i-BFM ayincibiliki emijikelezweni elandelayo. Ngezinye izikhathi i-BFM iyasebenza kakhulu ekusakazeni izithako zibe yi-substrate kangangokuthi ukubuyela ekushiseni okufanayo kungase kungabangela ukuncibilika. Ukugoqa okunezinyathelo eziningi kungaba ithuluzi elilula nelisebenzayo lokukhiqiza izingxenye zezokwelapha ezibizayo.
Le nkinga ingaxazululwa! Kunezindlela zokuvimbela lokhu, indlela ephumelela kakhulu ukusebenzisa inani elifanele le-BFM. Uma ijoyinti lincane futhi lincane endaweni, kungabonakala kumangaza ukuthi ingakanani i-BFM edingekayo ukuze kuhlanganiswe ijoyinti kahle. Bala indawo ye-cubic yejoyinti bese uzama ukusebenzisa i-BFM eningi kancane kunendawo ebalwe. Umklamo wokufaka ongakwazi ukuxhunywa uyisokhethi elibolile elifana ne-ID yepayipi, okuvumela i-BFM ukuthi ihambe ngqo ku-ID yepayipi ngesenzo se-capillary. Shiya isikhala ekugcineni kwepayipi ukuze uvimbele isenzo se-capillary, noma uklame ijoyinti ukuze ipayipi likwazi ukuphuma kancane ngale kwendawo yejoyinti. Lezi zindlela zakha indlela enzima kakhulu yokuthi i-BFM ihambe iye ekugcineni kwepayipi, ngaleyo ndlela inciphise ingozi yokuvaleka.
Lesi sihloko sivela ngezikhathi ezithile futhi sidinga ukuxoxwa ngaso. Ngokungafani nama-solder fillets, adala amandla ejoyintini, ama-solder fillets amakhulu awachithi i-BFM futhi angaba yingozi. Okubalulekile yilokho okungaphakathi. Amanye ama-PM ayaphuka ema-fillets amakhulu ngenxa yokugcwala kwezingxenye eziphansi zokuncibilika ezingasabalali. Kulokhu, ngisho noma kukhathele kancane, i-fillet ingaqhekeka futhi ikhule ibe ukwehluleka okukhulu. Lapho kushiswa, ukuba khona okuncane okuqhubekayo kwe-BFM esibonakalayo sokujoyina ngokuvamile kuyindlela efanele kakhulu yokuhlola okubonakalayo.
