Kusindikiza kwa solder -> kuyika magawo --> reflow soldering --> AOI optical inspection --> kukonza --> subboard.
Zogulitsa zamagetsi zikutsata miniaturization, ndipo zida zomwe zidagwiritsidwa ntchito kale ndi pulagi sizingathe kuchepetsedwa. Zogulitsa zamagetsi zimakhala ndi ntchito zambiri, ndipo ma circuits ophatikizika (ICs) omwe amagwiritsidwa ntchito alibe zigawo za perforated, makamaka zazikulu, zophatikizika kwambiri za IC, zomwe zimayenera kugwiritsa ntchito zigawo za pamwamba. Popanga zinthu zambiri komanso kupanga zokha, fakitale iyenera kupanga zinthu zapamwamba kwambiri zotsika mtengo komanso zotulutsa zambiri kuti zikwaniritse zosowa za makasitomala ndikulimbitsa mpikisano wamsika. Kukula kwa zida zamagetsi, kupanga mabwalo ophatikizika (IC), komanso kugwiritsa ntchito mosiyanasiyana kwa zida za semiconductor. Kusintha kwaukadaulo wamagetsi ndikofunikira ndikuthamangitsa zomwe zikuchitika padziko lonse lapansi. Ndizotheka kuti pamene njira zopangira ma cpu apadziko lonse lapansi ndi opanga zida zopangira zithunzi monga Intel ndi AMD zapita patsogolo kupitilira ma nanometers a 20, kukula kwa smt, monga ukadaulo wapamsonkhano ndi njira, sichoncho.
Ubwino wa smt chip processing: kachulukidwe kakang'ono, kachulukidwe kakang'ono ndi kulemera kwazinthu zamagetsi. Voliyumu ndi kulemera kwa zigawo za chip ndi pafupifupi 1/10 chabe ya zigawo zachikhalidwe zamapulagi. Nthawi zambiri, SMT ikakhazikitsidwa, kuchuluka kwa zinthu zamagetsi kumachepetsedwa ndi 40% ~ 60%, kulemera kumachepetsedwa ndi 60% ~ 80%. Kudalirika kwakukulu komanso mphamvu zotsutsana ndi kugwedezeka. Kuwonongeka kwa ma solder ndi otsika. Makhalidwe abwino apamwamba pafupipafupi. Chepetsani kusokoneza kwa ma electromagnetic ndi ma radio frequency. Ndikosavuta kuzindikira makinawo ndikuwongolera magwiridwe antchito. Chepetsani ndalama ndi 30% ~ 50%. Sungani zida, mphamvu, zida, ogwira ntchito, nthawi, ndi zina.
Ndi chifukwa chazovuta za kayendedwe ka smt patch processing kuti pakhala pali mafakitale ambiri a smt patch processing omwe amagwiritsa ntchito smt patch processing. Ku Shenzhen, chifukwa cha chitukuko champhamvu chamakampani opanga zamagetsi, smt patch processing akwaniritsa Kulemera kwamakampani.
