Ugcino lweumatshini wokuthambisa okhethiweyo wamaza
Kwizixhobo ezikhethiweyo zokuthambisa amaza, kukho iimodyuli ezintathu zokugcinwa ngokubanzi: imodyuli yokutshiza, imodyuli yokufudumeza, kunye nemodyuli yokuthambisa.
1. Ukugcinwa nokugcinwa kwemodyuli yokutshiza ngeFlux
Ukutshiza kwe-Flux kukhethiweyo kumxube ngamnye we-solder, kwaye ukugcinwa okufanelekileyo kunokuqinisekisa ukusebenza kwayo okuzinzile kunye nokuchaneka.Ngethuba lenkqubo yokutshiza, ngokuqhelekileyo kukho umbane omncinci oshiywe kwi-nozzle, kwaye i-solvent yayo iya kunyuka kwaye ivelise i-condensation.Ngoko ke, kuyimfuneko ukucoca umlomo kunye nommandla ojikelezileyo ngelaphu elingenathuli elifakwe etywaleni okanye ezinye izisombululo zendalo ngaphambi kokuba imveliso nganye iqale ukususa intsalela ephuma kumbhobho ukunqanda ukuvaleka komlomo kwaye kubangele ukugquma okungalunganga. iibhodi ezimbalwa zokuqala kwimveliso eqhubekayo.
Ukugcinwa ngokucokisekileyo kwe-nozzle kuyadingeka kwiimeko ezintathu ezilandelayo: ukusebenza ngokuqhubekayo kwesixhobo ukuya kwiiyure ezingama-3000;ukusebenza ngokuqhubekayo kwesixhobo unyaka omnye;kunye nokuqhubekeka kwemveliso emva kweveki enye yexesha lokuphumla.Ukugcinwa ngokucokisekileyo kufuneka kuhlawule ingqalelo ekucoceni kwangaphakathi kwe-nozzle, kunye nesixhobo sayo se-atomization sicoca ngokucokisekileyo ngokusebenzisa ukucocwa kwe-ultrasonic.Ngaphambi kokusebenzisa ukucocwa kwe-ultrasonic, isisombululo sokucoca sishushu malunga ne-65 ° C, enokuphucula amandla okucoca.Kwangaxeshanye, iindawo zokubhobhoza kunye nokutywinwa kwemodyuli yokutshiza kufuneka kwakhona zihlolwe kakuhle.
2. Ukugcinwa kwemodyuli yokufudumeza kwangaphambili
Ngalo lonke ixesha ngaphambi kokuba izixhobo zivulwe kwaye zisetyenziswe, imodyuli yokufudumala kufuneka ihlolwe ukuze ibone ukuba iglasi yokushisa ephezulu iphukile kwaye igxothwe, kwaye ukuba kunjalo, kufuneka itshintshwe ngexesha.Ukuba akunjalo, kufuneka usebenzise ilaphu elithambileyo lomqhaphu elifakwe emanzini okanye etywaleni ukuze usule izinto ezingcolisa umphezulu wayo.Xa kukho i-residu enenkani ye-flux ebusweni bayo, ungasebenzisa isisombululo esikhethekileyo sokucoca ukucoca indawo yayo.
Kwimodyuli ye-preheat, i-thermocouple isetyenziselwa ukulinganisa ukushisa kwe-preheat kwaye inendima ebaluleke kakhulu.Ngokuqhelekileyo, i-thermocouple ifakwe ngokuhambelana nombhobho wokufudumeza.Kwinkqubo yokusetyenziswa, ukuba i-thermocouple kunye ne-tube yokufudumala ayihambelani, khangela ukuba yonakele, kwaye ubeke indawo ye-thermocouple ngexesha xa kufuneka.
3. Ukugcinwa kwemodyuli ye-welding
Imodyuli ye-welding yeyona modyuli echanekileyo kwaye ibalulekileyo kumatshini wokuwelda, ibekwe ngokubanzi kwindawo ephezulu yemodyuli yokufudumeza umoya oshushu, phakathi kwemodyuli yezothutho kunye nenxalenye engezantsi yemodyuli ye-welding, imeko yayo yokusebenza ichaphazela ngokuthe ngqo. umgangatho webhodi yesekethe welding, ngoko ke ukugcinwa kwayo kubaluleke kakhulu.
Xa i-wave iqala ukusebenza, ukuba i-nozzle ayimanziswanga ngokupheleleyo yi-solder, inxalenye engamanzi iya kuthintela ukuhamba kwe-solder, kwaye ukuzinza kwamaza kunye nokuchaneka kwe-welding kuya kuchaphazeleka kakhulu.Ngeli xesha, i-nozzle kufuneka isebenze ngokukhawuleza i-de-oxidation, ngaphandle koko i-nozzle iya kuxutywa ngokukhawuleza kwaye ikhutshwe.
Inkqubo ye-wave soldering iya kuvelisa inani elithile le-oxide (ikakhulu i-tin ash kunye nenkunkuma), xa ininzi kakhulu iya kuchaphazela ukuhamba kwe-tin, yeyona nto iphambili ye-solder engenanto kunye ne-bridging, kodwa iphinde ithintele i-nitrogen port, ukunciphisa indima. yokhuseleko nitrogen, ukuze oxidation ngokukhawuleza solder.Ngoko ke, kwinkqubo ye-welding ingqalelo ekususweni kwe-tin ash dross, kodwa kwakhona khangela ukuba i-outlet ye-nitrogen ivaliwe.
