Waa maxay SMT?
Smt, ama dusha sare ee korkiisa tikniyoolajiyadda, waa tikniyoolajiyad kudhaceysa qaybaha elektiroonigga ah si toos ah dusha sare ee guddiga wareejinta ee daabacan (PCB). Qaabkan ayaa si isa soo taraysa ugu sii caansanaa iyada oo ay ugu wacan tahay faa'iidooyinkeeda, oo ay ku jiraan awoodda loo adeegsado qaybaha yaryar, oo ay ku guuleystaan cufnaanta ka kooban, cufnaanta sare, iyo hagaajinta waxtarka wax soo saarka.
Waa maxay SMD?
SMD, ama dusha sare ee qalabka, waxaa loola jeedaa qaybaha elektiroonigga ah si gaar ah loogu talagalay in lagu isticmaalo SMT. Waxyaabahaan waxaa loogu talagalay inay si toos ah ugu baxaan dusha sare ee PCB, oo tirtiraya baahida loo qabo fuulitaanka dhaqanka.
Tusaalooyinka qaybaha 'SMD' waxaa ka mid ah iska caabin, daf-bixiyeyaal, diodo, taranka, kala-guurka, iyo wareegyada isku dhafan (ICS). Cabbirka isku-dhafka ah wuxuu u oggolaanayaa cufnaanta qaybta sare ee cufnaanta guddiga wareega, taasoo dhalisay howlo badan oo ku saabsan raad-ka yar.
Waa maxay farqiga u dhexeeya SMT iyo SMD?
Waa muhiim in la fahmo farqiga u dhexeeya kala duwanaanta tikniyoolajiyada dusha sare ee dusha sare (smt) iyo aaladda dusha sare ee aaladda dusha sare (smd). In kasta oo ay xiriir la leeyihiin, waxay ku lug leeyihiin dhinacyo kala duwan oo waxsoosaarka elektiroonigga ah. Waa kuwan qaar ka mid ah kala duwanaanshaha ugu muhiimsan ee u dhexeeya SMT iyo SMD:
Kooban
In kasta oo SMT iyo SMD ay yihiin fikrado kaladuwan, ay si dhaw ula socdaan. SMT waxaa loola jeedaa geedi socodka wax soo saarka, halka SMD loola jeedo nooca qaybaha loo adeegsaday hawsha. Isku-darka SMT iyo SMD, soo-saareyaashu waxay soo saari karaan wax yar, oo ka sii badan aalado elektiroonig ah oo iskuxiran oo leh wax qabad la xoojiyay. Teknolojiyaddani waxay ka hadashay warshadaha elektiroonigga ah, taas oo sameysay suurto gal casriga ah ee casriga ah, kombiyuutarada waxqabadka sare iyo aaladaha caafimaad ee horumarsan, iyo hal-abuurnimo kale.
