Izingxenye ze-elekthronikhi eziningi azikakafakwa phezulu kusetshenziswa i-SMD.Ngalesi sizathu, i-SMT kumele ifake izingxenye ezithile ze- through-hole.Izingxenye zokukhweza ezingaphezulu, ezisebenzayo nezingenzi lutho, lapho zinamathiselwe ku-substrate, zakha izinhlobo ezintathu eziyinhloko zemihlangano ye-SMT - evame ukubizwa ngokuthi Uhlobo I, Uhlobo II kanye Nohlobo III.Izinhlobo ezahlukahlukene zicutshungulwa ngokulandelana okuhlukile, futhi zontathu izinhlobo zidinga okokusebenza okuhlukile.
1. Izinhlobo ze-SMT zohlobo lwe-III ziqukethe kuphela izingxenye zokukhweza zangaphezulu (izimbangi, ama-capacitor nama-transistors) ezinamathiselwe ohlangothini olungezansi.
2.Izingxenye ze-Type I ziqukethe izingxenye zokukhweza phezulu kuphela.Izingxenye zingaba ngohlangothi olulodwa noma olukabili.
3. Izingxenye zohlobo lwe-II ziyinhlanganisela yoHlobo lwe-III noHlobo I. Ngokuvamile aluqukethe noma yimaphi amadivayisi okukhweza asebenzayo ohlangothini olungezansi, kodwa angaqukatha amadivaysi okukhweza angaphandle ahlukene ohlangothini olungezansi.
Uma iphimbo lilikhulu futhi lilihle, ubunkimbinkimbi bomhlangano we-SMT kumishini kagesi buzokhula.
I-Ultra-fine pitch, QFP (Quad Flat Pack), TCP (Tape Carrier Package) noma i-BGA (Ball Grid Array) kanye nezingxenye ze-chip ezincane kakhulu (0603 noma 0402 noma ezincane) zisetshenziselwa lezi zingxenye kanye nezendabuko (50 mil pitch )) iphakethe le-surface mount.
Izinqubo zazo zontathu izikhwebu ezingaphezulu zifaka - okunamathelayo, ukunamathisela i-solder, ukubeka, ukunamathisela nokuhlanza okulandelwa ukuhlolwa, ukuhlolwa nokukhanda.
I-Chengyuan Industrial Automation, umkhiqizi wemishini ye-SMT ochwepheshe.
