Qaybo badan oo elektaroonik ah ayaan wali dusha sare lagu rakibin iyadoo la isticmaalayo SMD.Sababtan awgeed, SMT waa inay dejiso qaybo daldalool ah qaarkood.Qaybaha dusha sare ee korka, firfircoon oo aan fiicneyn, marka lagu dhejiyo substrate, waxay sameeyaan seddex nooc oo waaweyn oo ah shirarka SMT - oo badanaa loo yaqaan Nooca I, Nooca II iyo Nooca III.Noocyada kala duwan ayaa loo habeeyaa si kala duwan, saddexda noocba waxay u baahan yihiin qalab kala duwan.
1. Nooca III SMT assemblies waxaa ku jira oo kaliya qaybaha buurta dusha kala duwan (iska caabiyeyaasha, capacitors iyo transistors) oo ku dheggan dhinaca hoose.
Qaybaha 2.Type I waxay ka kooban yihiin qaybaha dusha sare oo kaliya.Qaybuhu waxay noqon karaan hal dhinac ama laba-dhinac.
3. Qaybaha Nooca II waa isku-darka Nooca III iyo Nooca I. Sida caadiga ah kuma jiraan wax qalab korka korka ah oo firfircoon oo dhinaca hoose ah, laakiin waxay ku jiri karaan qalabka dusha sare ee discrete ee dhinaca hoose.
Haddii garoonku uu weyn yahay oo wanaagsan yahay, kakanaanta isu-ururinta SMT ee qalabka elektiroonigga ah ayaa kordhin doona.
Garoon aad u fiican, QFP (Quad Flat Package), TCP ( Xidhmada Qaadista Cajaladda) ama BGA (Ball Grid Array) iyo qaybo aad u yar oo jajab ah (0603 ama 0402 ama ka yar) ayaa loo isticmaalaa qaybahan iyo sidoo kale dhaqameed (50 mil garoonka) )) xirmo korka oogada.
Nidaamyada saddexda dusha sare ee korka ah waxaa ka mid ah - dhejisyada, koollada alxanka, meelaynta, alxanka iyo nadiifinta oo ay ku xigto kormeerka, tijaabinta iyo dayactirka
