Ukucubungula kwe-SMTiwuchungechunge lobuchwepheshe benqubo yokucubungula ngesisekelo se-PCB.Inezinzuzo zokunemba okuphezulu nokushesha okusheshayo, ngakho-ke yamukelwe abakhiqizi abaningi be-elekthronikhi.Inqubo yokucutshungulwa kwe-chip ye-SMT ikakhulukazi ihlanganisa ukukhipha isikrini sikasilika noma ukukhipha iglue, ukukhwezwa noma ukuphulukisa, ukuphinda kufakwe i-solder, ukuhlanza, ukuhlola, ukusetshenzwa kabusha, njll. Izinqubo eziningi zenziwa ngendlela ehlelekile ukuze kuqedelwe yonke inqubo yokucubungula i-chip.
1.Ukuphrinta kwesikrini
Imishini engaphambili etholakala kulayini wokukhiqiza we-SMT ingumshini wokuphrinta isikrini, umsebenzi wawo oyinhloko uwukuphrinta unamathisele we-solder noma ukunamathisela i-glue kumaphedi e-PCB ukuze ulungiselele ukuhlanganiswa kwezingxenye.
2. Ukukhipha
Imishini etholakala ekugcineni komugqa wokukhiqiza we-SMT noma ngemuva komshini wokuhlola kune-glue dispenser.Umsebenzi wayo oyinhloko ukulahla iglue endaweni engaguquki ye-PCB, futhi inhloso ukulungisa izingxenye ku-PCB.
3. Ukubekwa
Imishini engemuva komshini wokunyathelisa isikrini sikasilika emugqeni wokukhiqiza we-SMT ingumshini wokubeka, osetshenziselwa ukukhweza izingxenye ezingaphezulu ngokunembile endaweni egxilile ku-PCB.
4. Ukwelapha
Impahla engemuva komshini wokubeka emugqeni wokukhiqiza we-SMT iyisithando somlilo esiphilisayo, umsebenzi wayo oyinhloko uwukuncibilikisa ingcina yokubeka, ukuze izingxenye zokukhweza ezingaphezulu nebhodi le-PCB kuhlanganiswe ngokuqinile ndawonye.
5. I-Reflow soldering
Imishini engemuva komshini wokubeka emugqeni wokukhiqiza we-SMT ihhavini eligeleza kabusha, umsebenzi walo oyinhloko uwukuncibilikisa unamathisele we-solder ukuze izingxenye zokukhweza ezingaphezulu kanye nebhodi le-PCB kuhlanganiswe ngokuqinile ndawonye.
6. Ukutholwa
Ukuze kuqinisekiswe ukuthi ikhwalithi yokudayiswa kanye nekhwalithi yokuhlanganisa yebhodi le-PCB ehlanganisiwe ihlangabezana nezidingo zefekthri, izibuko zokukhulisa, ama-microscope, izihloli ezisesekhethini (ICT), izihloli zokuhlola endizayo, ukuhlola okuzenzakalelayo (AOI), amasistimu okuhlola i-X-RAY nezinye izinto zokusebenza ziyadingeka.Umsebenzi oyinhloko ukuthola ukuthi ingabe ibhodi le-PCB linazo yini iziphambeko ezifana nokusoda okubonakalayo, ukudayiswa okulahlekile, nokuqhekeka.
7. Ukuhlanza
Kungase kube nezinsalela zokudambisa eziyingozi emzimbeni womuntu njengokugeleza ebhodini le-PCB elihlanganisiwe, elidinga ukuhlanzwa ngomshini wokuhlanza.
