NgemvaI-SMT reflow solderingsizohlangabezana nezenzakalo ezithile ezinesici, lezi ziphambeko zokucubungula ze-SMT zizothinta ngokuqondile noma ngokungaqondile ikhwalithi yomkhiqizo.Lezi zenzakalo ezinesici zingabasebenzi be-SMT abacacile ekunqumeni kokukhubazeka kokucutshungulwa kwezichibi, ukuze kuhlinzekwe ibhentshimakhi yemboni yokuthuthukisa ukukhiqiza nokusebenza kwegama elibi.Ekucubunguleni isichibi sangempela salezi zenzakalo ezinesici ezitholiwe, kufanele zisetshenzwe kabusha ngokuqinile noma zilungiswe.Ngakho-ke kufanele siqonde kanjani ukuze sinqume lesi simo esibi?
Ngezansi ukuze ulungise okulandelayo:
1. (ngisho nethini) SMT processing welding even tin also known as tin bridge, between component ends, between solder joints of components, kanye namajoyinti e-solder nezintambo eziseduze, izimbobo, njll. akufanele zixhunywe yingxenye ye i-solder exhunywe ndawonye, imboni yokucubungula ye-SMT ebizwa ngokuthi ngisho ne-tin.
2. (itshe lesikhumbuzo) itshe lesikhumbuzo, elaziwa nangokuthi i-Manhattan phenomenon, libhekisela ekugcineni kokunamathisela okubili kwezingxenye ze-chip, ngemva kokuphinda kufakwe i-soldering, enye yezindawo zokunamathisela eziqhelelene nendawo yephedi yayo yonke ingxenye yayigobile futhi iqondile.Imboni ye-SMT ebizwa ngetshe lesikhumbuzo.
3. (i-side stand) i-chip component side kanye ne-PCB pad contact phenomenon.imboni ye-SMT ebizwa ngokuthi yi-side stand.
4. (i-offset) izingxenye endaweni evundlile ukuze zinyakaze, okuholela ekugcineni kwe-solder noma iphinikhodi ayinamathiselwe kuphedi ye-PCB.
5. (anti-mhlophe) ucezu lwengxenye engaphambili ku-PCB, uhlangothi oluphansi luye phezulu isenzakalo.
6. (ubuhlalu bethini) ekufakweni kwe-reflow soldering, okunamathiselwe ocezwini lwengxenye yengxenye noma kuhlakazwe emajoyini e-solder kujobelela ubuhlalu obuncane be-solder.
7. (i-cold soldering) i-reflow i-reflow into engaphelele, i-solder ayifinyeleli izinga lokushisa elincibilikayo noma ukushisa kwe-welding akwanele, ukuze iqiniswe ngaphambi kokumanzisa nokugeleza, akukho ukwakheka kwanoma yiluphi uhlaka lwe-alloy metal, ukuze konke noma ingxenye ye-solder esimweni esingeyona i-crystalline futhi ivele yakhe phezu kwensimbi ethengiswayo.
8. (i-core suction) i-solder esuka kuphedi eduze nephinikhodi ukuze ikhuphukele kuphini kanye nomzimba we-chip, okuholela ekukhiqizeni i-solder enganele noma engenalutho emajoyintini e-solder.
9. (reverse) ibhekisela ku-polarity yezingxenye emva kokushisela, i-polarity yesiqondiso sezidingo zangempela zokuqondisa ayihambisani.
10. (i-bubble) i-solder ekuqinisweni kwegesi ngaphambi kokwehluleka ukuphunyuka ngesikhathi, ukwakheka kwento engenalutho ngaphakathi kwe-solder joint.
11. (iphinifa) endaweni ehlangene ye-solder ukwenza izimbobo ezinjengezinaliti.
12. (i-fissure) amalunga e-solder ngenxa yokucindezeleka kwemishini noma ukucindezeleka kwangaphakathi okubangelwa isenzakalo samalungu aqhekekile we-solder.
13. (ithiphu ye-tin) ukushisela ithini elingaphandle eliphuma njengenaliti noma elinezipikili.
14. (i-tin eyengeziwe) i-soldering ku-solder ingaphezu kwenani elijwayelekile lesidingo, ukuze kube nzima ukubona uhlaka lwezingxenye ezidayisiwe noma i-solder ukwenza inqwaba ye-spherical.
15. (i-solder evulekile) izikhonkwane zengxenye / isiphetho se-solder yazo zonke eziphuma noma ezikude namaphedi azo ahambisanayo, futhi hhayi ngenxa yokudayiswa.
16. (amabala amhlophe) avele ku-substrate e-laminated ngaphakathi kwento ethile, lapho imicu yengilazi ekuphambanweni kwe-longitudinal ne-transverse kanye nokuhlukaniswa kwe-resin.Lesi senzakalo sibonakala njengamachashazi amhlophe ahlukene noma indawo engaphansi ngaphansi "kwesiphambano", ngokuvamile ehlotshaniswa nokwakheka kwengcindezi ngenxa yokushisa.
17. (i-welding grey) ngenxa yokushisa okuphezulu kwe-welding, ukuhwamuka kwe-flux ngokweqile kanye ne-welding ephindaphindiwe, njll., ubuso be-weld bumpunga, i-crystal solder ikhululekile, i-porous kanye ne-slag-like.
I-Zhejiang NeoDen Technology Co., LTD., eyasungulwa ngo-2010, ingumkhiqizi ochwepheshe okhethekile emshinini wokukhetha nendawo we-SMT, ihhavini eligeleza kabusha, umshini wokuphrinta we-stencil, ulayini wokukhiqiza we-SMT neminye Imikhiqizo ye-SMT.Sineqembu lethu le-R & D kanye nemboni yethu, sisebenzisa i-R&D yethu ecebile enokuhlangenwe nakho, ukukhiqizwa okuqeqeshwe kahle, sazuza idumela elihle kumakhasimende omhlaba wonke.
Sisesimweni esihle hhayi nje ukukunikeza umshini we-pnp wekhwalithi ephezulu, kodwa futhi nenkonzo enhle kakhulu ngemuva kokuthengisa.
Onjiniyela abaqeqeshwe kahle bazokunikeza noma yikuphi ukwesekwa kwezobuchwepheshe.
Ithimba lesevisi yonjiniyela abayi-10 elinamandla ngemva kokuthengisa lingaphendula imibuzo yamakhasimende kanye nemibuzo phakathi namahora angu-8.
Izixazululo zobungcweti zinganikezwa phakathi kwamahora angu-24 kokubili usuku lokusebenza namaholide.
