SMD ni impfunyapfunyo ya Surface Mounted Device, ikubiyemo ibikoresho nkibikombe byamatara, utwugarizo, chip, isasu, na epoxy resin muburyo butandukanye bwamasaro yamatara, hanyuma ikora moderi yerekana LED mubigurisha kubibaho bya PCB muburyo bwa ibishishwa.

SMD yerekana muri rusange isaba LED isaro gushyirwa ahagaragara, ntabwo byoroshye gusa guterana amagambo hagati ya pigiseli, ariko kandi bivamo imikorere mibi yo gukingira, bigira ingaruka kumikorere yubuzima ndetse nubuzima bwa serivisi.

Igishushanyo mbonera cya microstructure ya SMD

COB, mu magambo ahinnye yitwa Chip On Board, bivuga tekinoroji yo gupakira LED ikomatanya neza ibyuma bya LED ku mbaho ​​zicapye (PCBs), aho kugurisha ibipapuro byerekana imiterere ya LED kuri PCB.

Ubu buryo bwo gupakira bufite ibyiza bimwe mubikorwa byo gukora no gukora neza, ubwiza bwamashusho, kurinda, hamwe na mikoro ntoya.
