Ewe.I-304 insimbi engenasici ingathengiswa ngokufanelekileyo kwi-copper kwi-vacuum isebenzisa iintlobo ezahlukeneyo kunye ne-chemical soldering additives (BFM).Iintsimbi zokuzalisa ezisekelwe kwigolide, isilivere kunye ne-nickel zinokusebenza.Ekubeni ubhedu lukhula kancinci ngaphezu kwe-304 yensimbi engenasici, ingqalelo ekhethekileyo kufuneka ihlawulwe kwi-configuration yokudibanisa.Kule meko, amandla obhedu aya kuba aphantsi kakhulu, ngoko angakwazi ukufaka insimbi engenasici ngaphandle kokuguqulwa okubonakalayo.
Iindibano zebrazed zidla ngokuqhutywa kumaqondo obushushu ukuya kuthi ga kwi-4° Kelvin.Kukho uqwalaselo loyilo kunye nemida, kodwa igolide kunye nesilivere esekwe kwiintsimbi zokuzalisa ziqhele ukusetyenziswa kwesi sicelo.
3. Ndidinga ukuthengisa indibano enzima, kodwa andazi ukuba ndingathengisa njani yonke into ngaxeshanye.Ngaba i-multi-step soldering of components inokwenzeka?
Ewe!Umthengisi we-solder ochwephesha unokucwangcisa inkqubo ye-solder ye-multi-step.Cinga ngezinto ezisisiseko kunye ne-BFM ukwenzela ukuba i-solder ye-original joint ayinyibiliki kwi-run elandelayo.Ngokuqhelekileyo, umjikelo wokuqala uqhuba kwiqondo lokushisa eliphezulu kunemijikelezo elandelayo kwaye i-BFM ayiphindi ibuyele kwimijikelezo elandelayo.Ngamanye amaxesha i-BFM isebenza kakhulu ekusasazeni izithako kwi-substrate kangangokuba ukubuyela kubushushu obufanayo kunokubangela ukunyibilika kwakhona.I-soldering yamanyathelo amaninzi ingaba sisixhobo esifanelekileyo kunye nesisebenzayo sokuvelisa amacandelo ezonyango abiza kakhulu.
Le ngxaki ingasonjululwa!Kukho iindlela zokuthintela oku, eyona ndlela isebenzayo kukusebenzisa inani elifanelekileyo le-BFM.Ukuba umdibaniso uncinci kwaye uncinci kwindawo, kunokubonakala kumangalisa ukuba ingakanani i-BFM efunekayo ukuthengisa ngokufanelekileyo ukudibanisa.Bala indawo ye-cubic yendawo edibeneyo kwaye uzame ukusebenzisa i-BFM encinci kunendawo ebalwayo.Uyilo lwe-pluggable fitting luyi-socket enesithukuthezi, efana nobubanzi obungaphakathi bombhobho, ovumela i-BFM ukuba ihambe ngokuthe ngqo kwi-diameter yangaphakathi yombhobho ngesenzo se-capillary.Shiya igumbi ekupheleni kwetyhubhu ukukhusela isenzo se-capillary, okanye uyilo ukudibanisa ukuze i-tubing ikwazi ukuphuma kancinci ngaphaya kwendawo yokudibanisa.Ezi ndlela zenza indlela enzima ngakumbi ukuba i-BFM ihambe ukuya ekupheleni kombhobho, ngaloo ndlela inciphisa umngcipheko wokuvala.
Lo mxholo uvela amaxesha ngamaxesha kwaye kufuneka uxoxwe.Ngokungafani neefayili ze-solder, ezenza amandla kwi-joint, iifayili ezinkulu ze-solder azichithi i-BFM kwaye zinokuba yingozi.Okubalulekileyo koko kungaphakathi.Ezinye ii-PM zi-brittle kwiifillet ezinkulu ngenxa yoxinaniso lwamacandelo angadibanisiyo asezantsi.Kule meko, nangona ukukhathala okuncinci, i-fillet inokuqhekeka kwaye ikhule ibe yintlekele.Xa i-soldering, ubukho obuncinci, obuqhubekayo be-BFM kwi-interface edibeneyo ngokuqhelekileyo yeyona ndlela ifanelekileyo yokuhlola okubonakalayo.
