Waa maxay SMT?
SMT, ama tignoolajiyada dusha sare, waa tignoolajiyada si toos ah ugu dhejisa qaybaha elektiroonigga ah dusha sare ee looxa wareegga daabacan (PCB). Habkani wuxuu noqonayaa mid caan ah sababtoo ah faa'iidooyin badan, oo ay ku jiraan awoodda isticmaalka qaybo yaryar, gaaritaanka cufnaanta qaybaha sare, iyo hagaajinta waxtarka wax soo saarka.
Waa maxay SMD?
SMD, ama Surface Mount Device, waxa loola jeedaa qaybaha elektiroonigga ah ee si gaar ah loogu talagalay isticmaalka SMT. Qaybahan waxaa loogu talagalay in ay si toos ah ugu dhejiyaan dusha PCB, iyaga oo meesha ka saaraya baahida loo qabo ku dhejinta godad dhaqameed.
Tusaalooyinka qaybaha SMD waxaa ka mid ah resistors, capacitors, diodes, transistors, iyo circuits isku dhafan (ICs). Cabbirkeeda is haysta waxay u oggolaaneysaa cufnaanta qaybaha sare ee guddiga wareegga, taasoo keentay shaqeyn badan oo raad yar.
Waa maxay faraqa u dhexeeya SMT iyo SMD?
Waa muhiim in la fahmo faraqa u dhexeeya tignoolajiyada sare ee dusha sare (SMT) iyo aaladaha dusha sare (SMD). Inkasta oo ay isku xidhan yihiin, haddana waxay ku lug leeyihiin dhinacyo kala duwan oo wax-soo-saarka elegtarooniga ah. Waa kuwan qaar ka mid ah faraqa u dhexeeya SMT iyo SMD:
Soo koobid
Inkasta oo SMT iyo SMD ay yihiin fikrado kala duwan, waxay aad isugu dhow yihiin. SMT waxaa loola jeedaa habka wax soo saarka, halka SMD ay tilmaamayso nooca qaybaha loo isticmaalo habka. Marka la isku daro SMT iyo SMD, wax-soo-saarayaashu waxay soo saari karaan qalab elektaroonig ah oo yaryar oo is haysta. Farsamadani waxa ay wax ka beddeshay warshadaha elektaroonigga ah, iyada oo suurtogelisay talefannada casriga ah ee casriga ah, kombuyuutarrada waxqabadka sarreeya iyo aaladaha caafimaadka ee horumarsan, iyo kuwa kale oo cusub.
