Weya Appleinkampaniukusetshenziswa kobuchwepheshe bokushaja okungenantambo ku-iPhone 8, itis kwavutha imboni yonke.Njengomthengi ojwayelekile, ngaphezu kokusebenzisa amashaja angenawaya nsuku zonke, uyakwenzayaziKanjanikwenzaishaja engenantambobekukhiqizwa?Manje sithathaiinqubo yokucubungula yeshaja engenantambo.Silandele ezinyathelweni zami futhi ngizokukhombisa inqubo yokukhiqiza yokushaja okungenantambo endaweni yokusebenzela yakwaLantaisi.
Ukushaja okungenantambo kuhlukaniswe izingxenye ezimbili: ibhodi lesifunda langaphakathi kanye nengxenye yangaphandle.Inqubo yokukhiqiza yokushaja okungenantambo izophinde yethulwe ngokuningiliziwe kulezi zinhlangothi ezimbili.
Okokuqala, ukuthengisa kwethu namakhasimende akhe bayaxhumana ukuze banqume ukwakheka komkhiqizo nezidingo zokusebenza.Okulandelayo, umnyango wezobuchwepheshe waseLanaisi uzoklama ibhodi lesifunda sangaphakathi, futhi umnyango womkhiqizo uzoklama isakhiwo segobolondo.
Isinyathelo 1 :Isithombe esingenhla siyibhodi elingenalutho elingenazo izingxenye ze-elekthronikhi.Okokuqala, izofakwa emshinini wokunyathelisa ozenzakalelayo ngokugcwele futhi ipendwe ngongqimba lwe-solder paste.I-solder paste ixubene ne-solder powder, i-flux, namanye ama-surfactants kanye nama-thixotropic agents.Kuyabonakala esithombeni ukuthi leli bhodi lesekhethi yeshaja engenantambo linezingxenye ezingaphezu kwama-30.
(Isithombe esingenhla sibonisa umshini wokuphrinta ozenzakalelayo ngokuphelele.)
Isinyathelo sesi-2:Bese ufaka inqubo elandelayo: Isichibi se-SMT.I-SMT imele ubuchwepheshe be-surface mount futhi isetshenziswa kakhulu embonini ye-electronics.Isetshenziselwa kakhulu ukufakwa kwezingxenye ze-elekthronikhi ezingenawo umkhondo noma imikhondo emifushane.
Isinyathelo sesi-3:Umshini wokubeka we-SMT ufaka futhi ulungise ama-chips, resistors, capacitor, inductors nezinye izingxenye ebhodini lesekethe elixutshwe ngokunamathisela kwe-solder ngokulandelana.Umshini ngamunye wokubeka i-SMT onesivinini esiphezulu uzolawulwa ikhompuyutha encane.Onjiniyela bazoklama futhi bahlele izinqubo zokusebenza ezisethiwe ngokuya ngezinto zebhodi lesekethe yokushaja okungenantambo, okuthuthukisa kakhulu ukunemba kokubekwa kwebhodi lesekethe.
Isinyathelo sesi-4:Isithombe esingenhla sibonisa ukusebenza kwe-reflow soldering yenqubo yokuvikela imvelo engenamthofu.Engakwesokudla yimishini yokuphinda ifakwe emanzini enezinga lokushisa langaphakathi elingaphezu kwama-degree angu-200.I-substrate ye-PCB ngemva kokuxubha, ukuchibiyela, kanye ne-reflow soldering isiphenduke i-PCBA ephelele.Ngalesi sikhathi, i-PCBA idinga ukuhlolwa ukuze kutholwe ukuthi ingabe imisebenzi yengxenye ngayinye ijwayelekile.
Isinyathelo sesi-5:Isithombe esingenhla sibonisa ukusetshenziswa komtshina wokubona ozenzakalelayo we-AOI ukuhlola i-PCBA.Ezikhathini eziyishumi zokukhuliswa, ungabheka ngezithombe ukuthi azikho yini izinkinga ezifana nokunamathisela okungelona iqiniso kanye ne-solder engenalutho phakathi nenqubo yokubeka i-chip namandla okumelana.
Isinyathelo sesi-6:Ibhodi le-PCBA eliqeqeshiwe lizothunyelwa kunqubo elandelayo-ukushisela ikhoyili yokudlulisela.
Isinyathelo sesi-7:Ukushisela ikhoyili yokudlulisela kudinga ukusebenza ngezandla.Kuyabonakala esithombeni ukuthi uchwepheshe une-wristband eluhlaza okwesibhakabhaka esandleni sakhe sobunxele.Kukhona intambo kule wristband esekelwe ukuvimbela ugesi omile womzimba womuntu ukuthi ungangeni ku-chip enembayo ephezulu.
Isinyathelo sesi-8:Okulandelayo, hlola ukuthi ibhodi yekhoyili yokudlulisa ingasebenza ngokujwayelekile yini.Lapha, izimo zokusebenza zama-voltages ahlukene wokufaka zizohlolwa.
(Isithombe esingenhla sibonisa amandla kagesi kanye nezamanje uma ishaja engenantambo ishaja ngokushesha, 9V/1.7A.)
Isinyathelo 9:Le nqubo iwukuhlola ukuguga.Ishaja ngayinye engenantambo efanelekayo idinga ukuhlolelwa amandla nokulayisha ngaphambi kokuphuma efekthri, ukuze imikhiqizo engasebenzi kahle ihlolwe kusenesikhathi phakathi nenqubo yokuhlola;labo abaphumelele ukuhlolwa kokuguga bazongena enqubweni yomhlangano, futhi abanesici bazoba Yikhiphe ukuze kuxazululwe inkinga.Ngokukanjiniyela wefekthri, ukushaja okungenantambo kwekhoyili eyodwa kudinga ukuhlolwa kokuguga kwamahora angu-2, kuyilapho ikhoyili ekabili ingamahora angu-4.
Isithombe esingenhla sibonisa ibhodi lesifunda lokushaja okungenantambo ngemva kokuhlolwa kokuguga, futhi ucezu ngalunye luhlelwe ngobunono.Lawo anezakhi ze-elekthronikhi abheke phansi ukuze agweme ukuwalimaza ngesikhathi sokungqubuzana.
Isinyathelo 10 :Lungisa imojuli yesidlulisi kugobolondo leshaja engenantambo ngeglue engu-3M.
Isithombe esingenhla sibonisa ishaja engenantambo eqedwe kancane ehlanganisiwe futhi isizolinda isixhumanisi somhlangano esilandelayo.
Isinyathelo 11:Bopha izikulufu.
Ishaja eqondile engenantambo enokushaja okusheshayo kwamakhoyili amabili iphelile.
Isinyathelo 12 :Iqedile ukuhlola umkhiqizo ngaphambi kokuthunyelwa.Lesi sixhumanisi sisetshenziselwa ukuqeda ukuhambisana kokushaja okungenantambo, kanye nokuqinisekisa ukuthi umkhiqizo wokushaja okungenantambo ofika esandleni somsebenzisi ungaba nomuzwa wokusebenza ofanayo noweshaja yasekuqaleni.
Isinyathelo 13 :Faka umkhiqizo esikhwameni se-PE, uwufake kumanuwali, ikhebula ledatha yohlobo C, bese uwupakisha ebhokisini, bese uyawupakisha bese ulinda ukuthunyelwa.
Okungenhla inqubo ephelele yokukhiqiza yokushaja okungenantambo.Ngamafuphi, ukuphrinta kwebhodi okungenalutho, i-SMT patch, i-reflow soldering, ukuhlolwa kwe-PCBA, ikhoyili e-soldering, ukuhlola, ukuhlolwa kokuguga, iglue, ukuhlanganiswa kwegobolondo, ukuhlolwa komkhiqizo oqediwe, kanye nokupakishwa komkhiqizo ophelile.
(Yebo, ukuze siqinisekise ukuphepha nokuthembeka kwemikhiqizo yethu, sizohlola isikhunta, ukuhlola ukusebenza kwe-elekthronikhi, ukuhlola ukubukeka, njll., ukushaja okungenantambo.)
Ngemva kokuyifunda, ingabe unakho ukuqonda okuningiliziwe ngenqubo yokukhiqiza engaqondakali yokushaja okungenantambo?Ukuze uthole imininingwane eyengeziwe, sicela uthinte uLantaisi, sizobe sisenkonzweni yakho phakathi namahora angama-24.
