Waa maxay SMT?
SMT, ama tiknoolajiyada dusha sare ee lagu rakibayo, waa tiknoolajiyad si toos ah ugu rakibta qaybaha elektaroonigga ah dusha sare ee looxa wareegga daabacan (PCB). Habkani wuxuu noqonayaa mid caan ah sababtoo ah faa'iidooyin badan oo uu leeyahay, oo ay ku jiraan awoodda loo leeyahay in la isticmaalo qaybo yaryar, la gaaro cufnaanta qaybaha oo sareysa, iyo in la hagaajiyo hufnaanta wax soo saarka.
Waa maxay SMD?
SMD, ama Surface Mount Device, waxaa loola jeedaa qaybaha elektarooniga ah ee si gaar ah loogu talagalay in lagu isticmaalo SMT. Qaybahan waxaa loogu talagalay inay si toos ah ugu rakibaan dusha sare ee PCB, taasoo meesha ka saaraysa baahida loo qabo rakibidda godadka dhaqameed.
Tusaalooyinka qaybaha SMD waxaa ka mid ah iska caabinta, capacitors-ka, diode-yada, transistors-ka, iyo wareegyada isku dhafan (ICs). Cabbirkeeda is haysta wuxuu u oggolaanayaa cufnaanta qaybaha oo sareysa guddiga wareegga, taasoo keentay shaqeyn dheeraad ah oo ku jirta raad yar.
Waa maxay farqiga u dhexeeya SMT iyo SMD?
Waa muhiim in la fahmo farqiga u dhexeeya tiknoolajiyada kor u qaadista dusha sare (SMT) iyo aaladaha kor u qaadista dusha sare (SMD). Inkasta oo ay isku xiran yihiin, haddana waxay ku lug leeyihiin dhinacyo kala duwan oo wax soo saarka elektaroonigga ah. Waa kuwan qaar ka mid ah faraqa ugu muhiimsan ee u dhexeeya SMT iyo SMD:
Soo Koobid
In kasta oo SMT iyo SMD ay yihiin fikrado kala duwan, haddana si dhow ayay isugu xiran yihiin. SMT waxay tilmaamaysaa habka wax soo saarka, halka SMD ay tilmaamayso nooca qaybaha loo isticmaalo habka. Iyagoo isku daraya SMT iyo SMD, soosaarayaashu waxay soo saari karaan aalado elektaroonig ah oo yaryar oo isku dhafan oo leh waxqabad la wanaajiyey. Tiknoolajiyaddani waxay kacaan ku samaysay warshadaha elektaroonigga ah, iyadoo suurtogal ka dhigaysa taleefanno casri ah oo casri ah, kombiyuutarro waxqabad sare leh iyo aalado caafimaad oo horumarsan, iyo hal-abuurro kale.
