Marka labaad, scd dusha sare ee smd dusha sare ee SMD waxay leedahay wax qabad ku saabsan buuga. Waxay si wax ku ool ah uga go'doomi karaan gudbinta iyo helitaanka calaamadaha, ka hortagga faragelinta, iyo joogtaynta sharafta calaamadda. Ka sarreynta waxqabadka go'doominta ayaa hubin kara howlgalka wax ku oolka ah ee nidaamka iyo yareynta faragelinta calaamadaha.
Intaas waxaa sii dheer, wareegga dusha sare ee SMD wuxuu sidoo kale leeyahay xasillooni heerkul heer sare ah. Waxay ku shaqeyn karaan tirada heerkulka ballaaran, sida caadiga ah waxay gaaraan heerkulka oo u dhexeeya -40 ° C illaa + 85 ° C, ama xitaa ballaaran. Deganaanshani waxay awood u siineysaa wareegga dusha sare ee SMD inay ku shaqeeyaan si ku kalsoon deegaanno kala duwan.
Qaabka baakada ee SMD dusha sare ee SMD ee SMD ayaa sidoo kale ka dhigaysa mid sahlan oo lagu dhexgalo oo lagu rakibo. Waxay si toos ah ugu rakibi karaan aaladaha wareega ee PCBs iyagoo maraya tikniyoolajiyadda kor u kaca, iyada oo aan loo baahnayn in la galiyo fulinta dhaqameed ama hababka loo iibiyo. Qaabkan dusha sare ee baakadaha oo keliya ma fiicna hufnaanta wax soo saarka, laakiin sidoo kale waxay awood u siineysaa is dhexgalka cufnaanta sare, taas oo ku keydisaa meel bannaan oo fududeynaya qaabeynta nidaamka.
Intaas waxaa sii dheer, wareegga dusha sare ee SMD waxay leeyihiin dalabyo ballaaran oo ku saabsan nidaamyada isgaarsiinta sare iyo qalabka microwave-ka. Waxaa loo isticmaali karaa in lagu go'doomiyo calaamadaha u dhexeeya masaafada rf iyo anteenooyinka, hagaajinta waxqabadka nidaamka iyo xasilloonida. Intaas waxaa sii dheer, waxaa sidoo kale loo isticmaali karaa aaladaha wireless-ka ah sidoo kale waxaa loo isticmaali karaa aaladaha wireless-ka ah, sida isgaarsiinta wireless-ka, nidaamyada radar, iyo isgaarsiinta dayax gacmeedka, si ay u buuxiyaan baahiyaha is-soo-nooleynta iyo qurxinta.
Marka la soo koobo, wareegga dusha sare ee SMD waa is haysta, khafiif ah, oo sahlan in lagu rakibo aaladda qaab-qaabeysan oo leh caymis ballaaran, waxqabadka go'doominta ee wanaagsan, iyo xasilloonida heerkulka, iyo xasilloonida heerkulka. Waxay leeyihiin codsiyo muhiim ah oo ku yaal meelaha ay ka mid yihiin nidaamyada isgaarsiinta sare, qalabka microwave, iyo qalabka raadiyaha. Iyada oo horumarka joogtada ah ee tikniyoolajiyadda, SMD dusha sare ee SMD Squares waxay door muhiim ah ka ciyaari doonaan meelo badan waxayna gacan ka geysan doonaan horumarinta tikniyoolajiyadda isgaarsiinta ee casriga ah.
Wareegtada Tooshka ee RF ee RF Mabda 'shaqadeeda shaqadu wuxuu ku saleysan yahay wareejinta wareejinta iyo soo-celinta magnetic-ka ifafaaleyaasha elektaroonigga ah ee elektromagens. Muuqaalka ugu weyn ee aaladdan ayaa ah in loo oggolaado calaamadaha jihada gaarka ah si ay u gudbaan inta ay xayiran yihiin calaamadaha jihada ka soo horjeedda.
Wareegtada RF SMT waxay ka kooban tahay saddex dekedood, oo mid kastaaba u adeegi karo sidii wax soo saar ama wax soo saar. Marka signal uu galo dekedda, waxaa loo habeeyaa dekada xigta ka dibna wuxuu ka baxaa dekada saddexaad. Jihada qulqulka calaamadahan badanaa waa saacad-saacadeed ama isbadal dhanka dambe ah. Haddii calaamadda seenyaalaha ay ku faafayaan jihada lama filaanka ah, wareegga wareegga ayaa xannibi doona ama nuugi doona calaamadaha si looga fogaado faragalinta faragalinta qaybaha kale ee nidaamka ka soo baxa nidaamka kale.
Faa'iidooyinka ugu weyn ee wareegga-RF SMT waa midnimadooda iyo is dhexgalka sare. Sababta oo ah isticmaalka dusha sare ee tikniyoolajiyadda dusha sare, wareegan wareegga ayaa si toos ah loogu rakibi karaa guddiga wareega ah iyada oo aan loo baahnayn xargaha isku xirka fiilooyinka ama xiriiriyeyaasha. Tani kaliya ma dhimayso mugga iyo culeyska qalabka, laakiin sidoo kale waxay fududeysaa rakibaadda iyo habka dayactirka. Intaas waxaa sii dheer, qaabeynta isku-dhafan ee aadka u yar, oo ah wareegga RF Smt ayaa sida caadiga ah leh wax qabad iyo isku halayn wanaagsan.
Codsiyada wax ku oolka ah, wareegga RF SMT waxay door muhiim ah ka ciyaaraan nidaamyo badan oo RF ah. Tusaale ahaan, nidaamka radar, waxay ka hortegi kartaa dib-u-noqoshada calaamadaha ECHO inay soo galaan gudbiyaha, taas oo ka ilaalinaysa gudbinta waxyeelada. Nidaamyada isgaarsiinta, waxaa loo isticmaali karaa in lagu go'doomiyo gudbinta iyo helitaanka anteenooyinka si looga hortago in calaamadaha la isugu gudbiyo si toos ah galinta qaataha. Intaas waxaa sii dheer, sababtuna tahay is dhexgalka iyo is dhexgalka sare, wareegga RF Smt ayaa sidoo kale si weyn loogu isticmaalaa meelaha ay ka mid yihiin gawaarida maadaama aan la aqoon iyo isgaadhsiinta satalaytka.
Si kastaba ha noqotee, naqshadeynta iyo soo saarista wareegga RF Smt wareegyada ayaa sidoo kale la kulma caqabado qaarkood. Marka hore, mabdanahadiisa shaqadu waxay ku lug leedahay aragti adag oo koronto adag, naqshadeynta iyo hagaajinta wareegga wareegga wuxuu u baahan yahay aqoon xirfadeed oo qoto dheer. Marka labaad, isticmaalka dusha sare ee tikniyoolajiyadda dusha sare, geedi socodka wax soo saarka ee wareegga ayaa u baahan qalab sax ah iyo xakameyn tayo adag leh. Ugu dambeyntiina, deked kasta oo wareegga wareegga uu u baahan yahay inuu si sax ah u iswaafajiyo soo noqnoqoshada seenyaalaha ee la socodsiinayo, tijaabinta iyo dib-u-dejinta wareegga ayaa sidoo kale u baahan qalab xirfad leh iyo teknolojiyad.
