SMD waa soo gaabinta Aaladda Dusha sare, kaas oo koobaya agabka sida koobabka laambada, biraha, chips, lead, iyo resin epoxy siyaalo kala duwan oo kuul laambado ah, ka dibna waxay sameeyaan modules soo bandhigida LED-ka iyagoo ku iibinaya guddiga PCB qaab ahaan balastar.

Bandhigyada SMD guud ahaan waxay u baahan yihiin kuul LED-yada in la soo bandhigo, taas oo aan si fudud u keenin hadal isdhaafsan oo u dhexeeya pixels, laakiin sidoo kale waxay keenaysaa waxqabadka ilaalinta liidata, saameeya waxqabadka sawirka iyo nolosha adeegga.

Jaantuska jaantuska ee qaab-dhismeedka yar yar ee SMD

COB, oo loo soo gaabiyo Chip On Board, waxaa loola jeedaa tignoolajiyada baakadaha LED-ka ee si toos ah u adkeeya chips-ka LED-ka looxyada wareegga daabacan (PCBs), halkii ay ka iibin lahaayeen baakadaha LED-yada gaarka ah ee PCB-yada.

Habka baakaduhu wuxuu leeyahay faa'iidooyin gaar ah xagga wax-soo-saarka iyo hufnaanta wax-soo-saarka, tayada sawir-qaadista, ilaalinta, iyo codsiyada kala dheeraynta yar yar.
