Marka loo eego habka isu-ururinta, qaybaha elektiroonigga ah waxaa loo qaybin karaa qaybo dalool ah iyo qaybaha dusha sare (SMC).Laakiin gudaha warshadaha,Qalabka Dusha sare (SMDs) waxaa loo isticmaalaa in ka badan si loo qeexo tan dusha sareqayb kuwaas oo ah loo isticmaalo qalabka elektarooniga ah ee si toos ah loogu dhejiyay dusha sare ee looxa wareegga daabacan (PCB).SMD-yadu waxay ku yimaadaan habab baakad oo kala duwan, mid walbana loogu talagalay ujeedooyin gaar ah, caqabadaha booska, iyo shuruudaha wax soo saarka.Waa kuwan qaar ka mid ah noocyada caanka ah ee baakadaha SMD:
1. Xirmooyinka SMD Chip (Ladigee ah)
SOIC (Small Outline Integrated Circuit): Baakad leydi ah oo leh hogaan laba dhinac ah, oo ku haboon wareegyada isku dhafan.
SSOP (Yaree Xidhmada Sharaxaada Yaryar): Waxay la mid tahay SOIC laakiin leh cabbirka jirka oo ka yar iyo garoon ka wanaagsan.
TSSOP (Xidhmada sharraxaadda yar ee khafiifka ah): Nooc ka khafiifsan SSOP.
QFP ( Xidhmada Guryaha Quad): Baakad labajibbaaran ama leydi leh oo leh hogaan afarta dhinac ah.Wuxuu noqon karaa mid-profile hoose (LQFP) ama mid aad u fiican (VQFP).
LGA (Land Grid Array): Hogaamiye ma jiro;Taa baddalkeeda, suufka xiriirka ayaa lagu habeeyay shabagyo ku yaal dusha hoose.
2. Xirmooyinka SMD Chip (Square)
CSP ( Xirmada Miisaanka Chip): Si aad ah ugu kooban kubbadaha alxanka tooska ah ee cidhifyada qaybta.Loogu talagalay inuu ku dhawaado cabbirka chip-ka dhabta ah.
BGA (Ball Grid Array): Kubadaha alxanka ah ayaa lagu habeeyey shabaqyada hoosteeda xirmada, taasoo bixisa kuleyl iyo waxqabad koronto oo aad u wanaagsan.
FBGA (Fine-Pitch BGA): Waxay la mid tahay BGA laakiin leh garoon ka wanaagsan cufnaanta qaybaha sare.
3. Xirmooyinka SMD Diode iyo Transistor:
SOT (Transistor Outline Yar): Baakad yar oo loogu talagalay diodka, transistor-ka, iyo qaybaha kale ee yar yar.
SOD (Small Outline Diode): Wuxuu la mid yahay SOT laakiin gaar ahaan loogu talagalay diodh-yada.
DO (Qodobka Diode): Baakado yaryar oo kala duwan oo loogu talagalay diodes iyo qaybaha kale ee yaryar.
4.Xirmooyinka Capacitor iyo Resistor SMD:
0201, 0402, 0603, 0805, iwm.: Kuwani waa xeerar nambareed oo ka dhigan cabbirrada qaybta tobnaadka millimitirka.Tusaale ahaan, 0603 waxay tilmaamaysaa qayb cabbiraysa 0.06 x 0.03 inji (1.6 x 0.8 mm).
5. Xirmooyinka kale ee SMD:
PLCC (Balaastig Leaded Chip Carrier): Baakad laba geesood ah ama leydi leh oo leh hogaan afarta dhinac ah, oo ku haboon IC-yada iyo qaybaha kale.
TO252, TO263, iwm.: Kuwani waa noocyada SMD ee xirmooyinka ka kooban godka-dhaqameedka sida TO-220, TO-263, oo leh hoos siman oo korka ah.
Mid kasta oo ka mid ah noocyada xirmadan waxay leedahay faa'iidooyin iyo faa'iido darrooyinkeeda marka loo eego cabbirka, sahlanaanta isu-ururinta, waxqabadka kulaylka, sifooyinka korantada, iyo qiimaha.Doorashada xirmada SMD waxay ku xiran tahay arrimo ay ka mid yihiin shaqada qeybta, booska guddiga ee jira, awoodaha wax soo saarka, iyo shuruudaha kulaylka.
