Ithini inqubo ye-SMT PCB Assembly?
Inqubo yokusebenzisa i-SMT ukwenza amadivaysi e-PCB ihlanganisa ukusetshenziswa kwemishini ezenzakalelayo ukuhlanganisa izingxenye zikagesi.Lo mshini ubeka lezi zinto ebhodini lesekethe, kodwa ngaphambi kwalokho, ifayela le-PCB kufanele lihlolwe ukuze kuqinisekiswe ukuthi alinazo izinkinga ezithinta ukwenziwa nokusebenza kwedivayisi.Ngemva kokuqinisekisa ukuthi yonke into ilungile, inqubo yokuhlanganisa i-SMT PCB ayikhawulelwe ekuhlanganiseni nasekubekeni izakhi noma izinhlanganisela ku-PCB.Kufanele kulandelwe inqubo elandelayo yokukhiqiza.
1. Faka i-solder paste
Isinyathelo sokuqala lapho uhlanganisa ibhodi le-SMT PCB ukusebenzisa ukunamathisela kokunamathisela.Ukunamathisela kungasetshenziswa ku-PCB ngobuchwepheshe besikrini sikasilika.Ingasetshenziswa kusetshenziswa i-PCB stencil ehambisana nefayela eliphumayo elifanayo le-CAD.Udinga kuphela ukusika ama-stencil usebenzisa i-laser bese usebenzisa i-soldering paste ezingxenyeni lapho uzothengisa khona izingxenye.Ukufakwa kwe-solder paste kumele kwenziwe endaweni epholile.Uma usuqedile ukufaka isicelo, ungalinda isikhathi esithile ukuze uhlanganise.
2. Ukuhlolwa kokunamathisela kwakho kwe-solder
Ngemuva kokuthi unamathisele we-solder usetshenziswe ebhodini, isinyathelo esilandelayo ukuwuhlola njalo ngokusebenzisa amasu okuhlola unamathisele we-solder.Le nqubo ibalulekile, ikakhulukazi lapho kuhlaziywa indawo yokunamathisela i-solder, inani le-solder paste elisetshenzisiwe, nezinye izici eziyisisekelo.
3. Ukuqinisekiswa kwenqubo
Uma kwenzeka ibhodi lakho le-PCB lisebenzisa izingxenye ze-SMT nhlangothi zombili, kuzoba nesidingo sokucabanga ukuphinda inqubo efanayo ukuze kuqinisekiswe uhlangothi lwesibili.uzokwazi ukulandelela isikhathi esifanele sokuveza ukunamathisela kwe-solder ekamelweni lokushisa lapha.Yilapho ibhodi lakho lesifunda selilungele ukuhlanganiswa.Izingxenye zisazolungela imboni elandelayo.
4. Izinsiza zomhlangano
Lokhu ngokuyisisekelo kusebenzisana ne-BOM (Bill of Materials) esetshenziswa yi-CM ukuze kuhlaziywe idatha.Lokhu kusiza ukuthuthukiswa kwezinsiza zokuhlanganisa ze-BOM.
5. Amakhithi okugcina anezinto
Sebenzisa ibhakhodi ukuze uyikhiphe esitokweni futhi uyifake kukhithi yokuhlanganisa.Uma izingxenye sezifakwe ngokugcwele kukhithi, ziyiswa emshinini wokukhetha nokubeka obizwa ngokuthi i-surface mount technology.
6. Ukulungiswa kwezingxenye zokubekwa
Ithuluzi lokukhetha nendawo lisetshenziswa lapha ukuze kubanjwe yonke into yokuhlanganisa.Lo mshini uphinde usebenzise i-cartridge efika nokhiye oyingqayizivele ohambisana nekhithi yokuhlanganisa ye-BOM.Umshini uklanyelwe ukutshela ingxenye ephethwe i-cartridge.
