Ezimweni eziningi, into enkulu kakhulu ethinta isikhathi sokuphila sei-soldering ironithiphu izinga lokushisa le-solder.
Ngaphambi kokuqaliswa okusemthethweni kwemithetho ye-RoHS (imikhawulo ezintweni eziyingozi) ngomhlaka-1 Julayi, 2006, kuvunyelwe intambo yomthofu.Ngemva kwalokho, ukusetshenziswa komthofu (kanye nezinto ezihlobene nakho) akuvunyelwe ngaphandle kwalezi zisetshenziswa nezinqubo ezilandelayo: amathuluzi ezokwelapha, okokuqapha nokuhlonza izinto, amathuluzi okulinganisa namathuluzi ikakhulukazi emkhakheni wezempi kanye ne-aerospace okuhlanganisa izinzwa zezimoto (amasistimu okulawula izimoto nemikhiqizo yama-airbag). ), imboni yezokuthutha ngololiwe, njll.
I-lead alloy tin wire ejwayelekile kakhulu ibonakala ngendawo yokuncibilika engaba ngu-180 degrees.Indawo encibilikayo yocingo oluvamile lwengxubevange engenamthofu icishe ibe ngamadigri angu-220.Umehluko wokushisa wama-degree angu-40 usho ukuthi ukuze uqedele okwanelisayoi-solderokuhlangene ngesikhathi esifanayo, sidinga ukwandisa izinga lokushisa esiteshini sokunamathisela (uma isikhathi se-solder sanda, kulula ukulimaza izingxenye kanye nebhodi le-PCB).Ukwenyuka kwezinga lokushisa kuzonciphisa impilo yesevisi ye-solder iron tip futhi kwandise i-oxidation phenomenon.
Isibalo esilandelayo sibonisa umphumela wokukhuphuka kwezinga lokushisa empilweni yesevisi ye-solder iron tip.Ukuthatha ama-degree angu-350 njengenani lereferensi, lapho izinga lokushisa likhuphuka lisuka ku-50 degrees kuya ku-400 degrees, impilo yesevisi yethiphu ye-soldering iron izoncishiswa ngesigamu.Ukwandisa izinga lokushisa lensizakalo yethiphu ye-soldering iron kusho ukuthi impilo yesevisi yethiphu ye-soldering iron iyancishiswa.
Ngokuvamile, izinga lokushisa le-soldering le-solder-free solder alloy linconywa ukuthi libe ngu-350 ℃.Nokho, isibonelo, ngenxa yokuthi usayizi wedivayisi yokukhweza engu-01005 mncane kakhulu, sincoma inqubo ye-solder engu-300-degree.
Ukubaluleka kokunemba
Kufanele uhlole izinga lokushisa elisebenzayo lesiteshi se-soldering njalo, elingakwazi ukwandisa kuphela impilo yesevisi ye-tip ye-soldering iron, kodwa futhi ugweme ukushisa okudlulele noma ukushisa okuphansi kwe-soldering lapho imikhiqizo ye-soldering.
Kokubili kungabangela izinkinga ngesikhathi sokushisa:
·Izinga lokushisa elidlulele: opharetha abaningi abaqeqeshiwe bazocabanga ukuthi kuyadingeka ukwandisa izinga lokushisa le-solder ukuze balungise inkinga lapho bethola ukuthi i-solder ayikwazi ukuncibilika ngokushesha.Kodwa-ke, ukwandisa izinga lokushisa kuzokwenza izinga lokushisa endaweni yokushisa libe phezulu kakhulu, okuzoholela ekuhlaselweni kwe-pad, ukushisa okweqile kwe-solder, kulimaze i-substrate kanye namalungu e-solder ngekhwalithi embi kakhulu.Ngesikhathi esifanayo, kuzokwandisa i-oxidation yethiphu ye-soldering iron futhi kubangele ukulimala kwethiphu ye-soldering iron.
·Izinga lokushisa eliphansi kakhulu le-solder lingase liholele esikhathini eside kakhulu sokuhlala ngesikhathi sokusoda kanye nokudlulisa ukushisa okubi kakhulu.Lokhu kuzothinta umthamo wokukhiqiza kanye nekhwalithi yamalunga abandayo e-solder.
Ngakho-ke, ukukalwa kwezinga lokushisa okunembile kubalulekile ukuze uthole izinga lokushisa lokulungiselela i-solder.
