Joalo ka ha bohle re tseba, theSMTmochinie ka sebelisoa ho kenya mefuta e mengata ea likarolo, kahoo ka kakaretso re e bitsa mochine oa SMT o sebetsang ka bongata, re sebelisa ts'ebetso ea SMT batho ba bangata ba na le lipotso, ke lisebelisoa tsa mofuta ofe tse ka kenngoa?Ka mor'a moo, re tla hlalosa mefuta e mene ea likarolo tsa thaba e tloaelehilengPNPmochini:
- resistor: hangata re ka sebelisa mochini oa ho khetha le ho beha ho beha mohanyetsi holim'a ntho.Hangata, re ka hlalosa boholo ba hona joale ba khanyetso ka limilimithara kapa lisenthimithara.Ho na le linomoro tse 'ne holim'a mohanyetsi.Tse peli tsa pele li emela bolelele ba khanyetso, 'me tse peli tsa ho qetela li emela bophara ba khanyetso.Ha re e kenya hape, hafeela e ntse e le ka har'a moeli oa phoso ea ho kenya, e ka nkoa e le ntho e tšoanelehang ea ho hanyetsa ho kenya 'me tšebeliso ea eona e ke ke ea ameha.
- Capacitor: ho na le mefuta e mengata ea li-capacitor, li-capacitor tsa ceramic le li-electrolytic capacitor li sebelisoa hangata.Li-capacitor li na le likarolo tse 'nè tse kholo, bokhoni, boholo, phoso le coefficient.Li-capacitor li ka kenngoa hape holim'a likarolo ka mochine oa mount.Ka kakaretso, boleng ba capacitance ea capacitor bo ka bontšoa ka linomoro tse tharo ho element, empa bakeng sa li-capacitor tsa ceramic, mohato ona o ka tlosoa.Re ka khetholla li-capacitor tse fapaneng ho latela 'mala, boholo le mohlala oa capacitor e kentsoeng.
- Inductance: Inductance e tšoana ka sebopeho le bokhoni, empa e lefifi ka 'mala ho feta bokhoni.Pele re kenya, re ka sebelisa mochine oa ho khetholla ho khetholla le boholo ba inductance, ebe re fumana hore na inductance e kentsoeng hona joale e tšoana le inductance, 'me qetellong chip e tla sebetsoa ke patch.
- Diode: diode e boetse e sebelisoa haholo indastering ea SMT.Khalase le li-diode tse tiisitsoeng ka polasetiki ke mefuta e tloaelehileng ea ho kenya 'me e na le lisebelisoa tse ngata bophelong ba letsatsi le leng le le leng, tse kang li-LED tse sebelisoang ka liselefouno.Li-Diode tsa lisebelisoa tse fapaneng li ka hlahisa leseli la mebala e fapaneng.Ho beha hantle ka achip mountermochinike tsela e khuts'oane ea tlhahiso ea bongata.
