Kuwala kotsogolera kwa SMD ndi COB kuwunikira kumapezeka ku Lediant. Kodi mukudziwa kusiyana pakati pawo? Ndiroleni ndikuuzeni.
Kodi SMD ndi chiyani? Zikutanthauza zipangizo zokwera pamwamba. Fakitale yopangira ma LED pogwiritsa ntchito njira ya SMD imakonza chip chopanda kanthu pa bulaketi, kulumikiza magetsi awiriwo ndi mawaya agolide, ndipo pamapeto pake imateteza ndi epoxy resin. ndipo ali ndi maubwino ang'onoang'ono, ngodya yobalalika yayikulu, mawonekedwe owoneka bwino, komanso kudalirika kwakukulu.
COB ndi chiyani? Amatanthauza chip pa bolodi. Mosiyana ndi SMD, yomwe imagulitsa mikanda ya nyali ku PCB, njira ya COB imayamba kuyika malo a silicon chip ndi thermally conductive epoxy resin (silver-doped epoxy resin) pamwamba pa gawo lapansi. Ndiye Chip LED amatsatiridwa ndi interconnection gawo lapansi ndi zomatira kapena sanali conductive guluu kudzera zomatira kapena solder, ndipo potsiriza kulumikiza magetsi pakati chip ndi PCB anazindikira ndi waya (golide waya) kugwirizana.
