SMT shine gajartawar Fasahar Motsi ta Surface, mafi mashahurin Fasaha da tsari a cikin masana'antar hada-hadar lantarki.Electronic circuit Surface Mount Technology (SMT) ana kiransa Surface Dutsen ko Fasahar Dutsen Surface.Wani nau'i ne na fasaha mai haɗawa da kewayawa wanda ke shigar da abubuwan haɗin ginin da ba su da guba ko gajeriyar gubar (SMC/SMD a Sinanci) a saman bututun da aka buga (PCB) ko wani farfajiyar ƙasa, sa'an nan kuma ya haɗa da walƙiya ta hanyar walƙiya mai reflow ko. tsoma walda.

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 ga zanen kewayawa, don haka kowane nau'in na'urorin lantarki suna buƙatar fasahar sarrafa guntu ta SMT daban-daban don sarrafawa.

Abubuwan tsari na asali na SMT sun haɗa da: bugu na allo (ko rarrabawa), hawa (warkarwa), walda reflow, tsaftacewa, gwaji, gyara.

1. Buga allo: Aikin bugu na allo shine zubar da manna solder ko faci a kan kushin solder na PCB don shirya walda na abubuwan da aka gyara.Kayan aikin da aka yi amfani da shi shine na'urar bugu na allo (na'urar bugu na allo), wanda ke gaban ƙarshen layin samar da SMT.

2. Glue spraying: Yana sauke manne zuwa kafaffen matsayi na PCB board, kuma babban aikinsa shine gyara abubuwan da ke cikin allon PCB.Kayan aikin da aka yi amfani da shi shine na'ura mai rarrabawa, wanda yake a gaban ƙarshen layin samar da SMT ko a bayan kayan gwaji.

3. Dutsen: Ayyukansa shine shigar da abubuwan haɗin ginin ƙasa daidai zuwa madaidaiciyar matsayi na PCB.Kayan aikin da aka yi amfani da shi shine na'ura mai sakawa na SMT, wanda ke bayan na'urar buga allo a cikin layin samar da SMT.

4. Curing: Its aiki shi ne don narke da SMT m domin surface taro aka gyara da PCB jirgin za a iya da tabbaci manne tare.Kayan aikin da aka yi amfani da shi yana warkar da tanderun wuta, wanda ke bayan layin samar da SMT SMT.

5. Reflow waldi: aikin reflow waldi ne don narke solder manna, sabõda haka, surface taro aka gyara da PCB jirgin da tabbaci tsaya tare.Kayan aikin da aka yi amfani da shi shine tanderun walda, wanda ke cikin layin samar da SMT a bayan injin sanya SMT.

6. Tsaftacewa: Aikin shine cire ragowar walda kamar juyi akan PCB da aka haɗa wanda ke cutar da jikin ɗan adam.Kayan aikin da aka yi amfani da shi shine na'urar tsaftacewa, matsayi ba za a iya gyarawa ba, yana iya zama a kan layi, ko ba a kan layi ba.

7. Ganewa: Ana amfani da shi don gano ingancin walda da ingancin taro na PCB da aka haɗa.Kayan aikin da aka yi amfani da su sun haɗa da gilashin ƙara girma, microscope, kayan gwajin kan layi (ICT), kayan gwajin allura mai tashi, gwajin gwaji na atomatik (AOI), tsarin gwajin X-ray, kayan aikin gwaji, da dai sauransu. Za'a iya saita wurin a daidai. wani ɓangare na layin samarwa bisa ga bukatun dubawa.

8.Repair: ana amfani dashi don sake yin aikin PCB wanda aka gano tare da kurakurai.Kayan aikin da aka yi amfani da su sune ƙera ƙarfe, wuraren gyaran gyare-gyare, da dai sauransu. Tsarin tsari yana ko'ina cikin layin samarwa.
