Umehluko phakathi kwe-SMD ne-COB encapsulation

Kokubili ukukhanya okuholelekile kwe-SMD kanye nokukhanya kwe-COB okuholelekile kuyatholakala ku-Lediant. Uyawazi umehluko phakathi kwabo? Ake ngikutshele.

Yini i-SMD? Kusho amadivaysi afakwe phezulu. Imboni yokupakisha ye-LED esebenzisa inqubo ye-SMD ilungisa i-chip engenalutho kubakaki, ixhuma ngogesi kokubili ngezintambo zegolide, futhi ekugcineni iyivikele nge-epoxy resin. futhi inezinzuzo zosayizi omncane, i-engeli enkulu yokuhlakazeka, ukufana okuhle okukhanyayo, nokuthembeka okuphezulu.

Iyini i-COB? Kusho i-chip ebhodini. Ngokungafani ne-SMD, edayisela ubuhlalu besibani ku-PCB, inqubo ye-COB iqala imboza indawo yokubeka i-silicon chip ene-thermal conductive epoxy resin (i-silver-doped epoxy resin) ebusweni be-substrate. Khona-ke i-chip ye-LED inamathele ku-interconnection substrate nge-glue conductive noma non-conductive ngokusebenzisa i-adhesive noma i-solder, futhi ekugcineni ukuxhumana kukagesi phakathi kwe-chip ne-PCB kutholakala ngocingo (igolide legolide) ukubopha.
