Ewe. Intsimbi engagqwaliyo engama-304 ingadityaniswa ngempumelelo nethusi kwi-vacuum kusetyenziswa iintlobo ngeentlobo kunye nezongezo zekhemikhali zokunyibilikisa (BFM). Iintsimbi zokuzalisa ezisekelwe kwigolide, isilivere kunye ne-nickel zinokusebenza. Ekubeni ubhedu lwanda kancinci kunentsimbi engagqwali engama-304, kufuneka kuqwalaselwe ngokukodwa uqwalaselo loqhagamshelo. Kule meko, amandla obhedu aya kuba sezantsi kakhulu, ngoko ke inokulingana nentsimbi engagqwaliyo ngaphandle kokuguquka okubonakalayo.
Iindibano ze-solder zihlala zisebenza kumaqondo obushushu afikelela kwi-4° Kelvin. Kukho izinto ekufuneka ziqwalaselwe kunye nemida yoyilo, kodwa iintsimbi zokuzalisa ezisekelwe kwigolide nesilivere zihlala zisetyenziswa kolu setyenziso.
3. Ndifuna ukunyibilikisa indibano enzima, kodwa andazi ukuba ndingayinyibilikisa njani yonke into ngaxeshanye. Ngaba kunokwenzeka ukuba ukunyibilikisa izinto nge-multi-step?
Ewe! Umthengisi oqeqeshiweyo we-soldering unokulungiselela inkqubo ye-soldering enamanyathelo amaninzi. Cinga ngezinto ezisisiseko kunye ne-BFM ukuze i-solder joint yokuqala inganyibiliki kwi-run elandelayo. Ngokwesiqhelo, umjikelo wokuqala usebenza kubushushu obuphezulu kune-run elandelayo kwaye i-BFM ayinyibiliki kwi-run elandelayo. Ngamanye amaxesha i-BFM isebenza kakhulu ekusasazeni izithako kwi-substrate kangangokuba ukubuyela kubushushu obufanayo kunokubangela ukunyibilika kwakhona. I-soldering enamanyathelo amaninzi inokuba sisixhobo esilula nesisebenzayo sokwenza izinto zonyango ezibizayo.
Le ngxaki ingasonjululwa! Kukho iindlela zokuthintela oku, eyona ndlela isebenzayo kukusebenzisa ubungakanani obufanelekileyo be-BFM. Ukuba ijoyinti incinci kwaye incinci kwindawo, kunokubonakala kumangalisa ukuba kufuneka i-BFM engakanani ukuze idibanise ijoyinti ngokufanelekileyo. Bala indawo yetyhubhu yejoyinti kwaye uzame ukusebenzisa i-BFM engaphezulu kancinci kunendawo ebaliweyo. Uyilo lokufakelwa olunokutsalwa yisokethi ebolileyo efana ne-ID yetyhubhu, evumela i-BFM ukuba ihambe ngqo kwi-ID yetyhubhu ngesenzo se-capillary. Shiya indawo ekupheleni kwetyhubhu ukuthintela isenzo se-capillary, okanye uyila ijoyinti ukuze ityhubhu iphume kancinci ngaphaya kwendawo yejoyinti. Ezi ndlela zenza indlela enzima ngakumbi yokuba i-BFM ihambe iye ekupheleni kombhobho, ngaloo ndlela inciphisa umngcipheko wokuvaleka.
Esi sihloko sivela ngamanye amaxesha kwaye kufuneka sixoxwe ngaso. Ngokungafaniyo nee-solder fillets, ezidala amandla kwijoyinti, ii-solder fillets ezinkulu aziyichithi i-BFM kwaye zinokuba yingozi. Okubalulekileyo kukuba yintoni engaphakathi. Ezinye ii-PMs zibuthathaka kwii-fillets ezinkulu ngenxa yoxinzelelo lwezinto ezingaphantsi kwe-melting point. Kwimeko enjalo, nokuba kudiniwe kancinci, i-fillet inokuqhekeka kwaye ikhule ibe yintlekele enkulu. Xa kudityaniswa i-solder, ubukho obuncinci, obuqhubekayo be-BFM kwi-joint interface buhlala buyindlela efanelekileyo yokuhlola ngokubonakalayo.
