Gabaɗaya, samfuran lantarki da muke amfani da su an yi su ne da PCB tare da nau'ikan capacitors, resistors da sauran kayan lantarki bisa tsarin zanen da'ira, don haka kowane nau'in na'urorin lantarki suna buƙatar nau'ikan fasahar sarrafa SMT daban-daban don sarrafawa.

Abubuwan tsari na asali na SMT: bugu na liƙa mai solder -> hawan SMT ->reflow tanda->AOIkayan aikidubawa na gani -> kulawa -> allo.

Saboda tsarin fasaha na sarrafa SMT mai rikitarwa, don haka akwai masana'antun sarrafa SMT da yawa, don ingancin SMT ya inganta, kuma tsarin SMT, kowane hanyar haɗi yana da mahimmanci, ba zai iya samun kuskure ba, a yau ƙananan gyara tare da kowa tare da kowa ya koyi SMT reflow. An ƙaddamar da na'ura mai waldawa da fasaha mai mahimmanci wajen sarrafawa.
