Labada laydhka ee SMD iyo iftiinka hoose ee COB ayaa laga heli karaa Lediant. Ma garanaysaa faraqa u dhexeeya? Aan kuu sheego.
Waa maxay SMD? Waxay ka dhigan tahay qalabka dusha sare lagu rakibay. Warshada baakadaha LED iyadoo la isticmaalayo habka SMD hagaajin chip qaawan on bracket, koronto ku xidha labada la fiilooyinka dahabka ah, iyo ugu dambeyntii waxa ay ka ilaalisa la epoxy resin.SMD isticmaalaa dusha mount technology (SMT), taas oo uu leeyahay heerka sare ee otomatiga ah, oo uu leeyahay faa'iidooyinka of size yar yar, xagal kala firdhiso weyn, lebbis dhalaalaya wanaagsan, iyo isku halaynta sare.
Waa maxay COB? Waxay ka dhigan tahay chip on board. Si ka duwan SMD, oo ka iibisa kuulka laambada PCB-ga, habka COB wuxuu marka hore daboolayaa barta meelaynta ee chip silikoon leh resin epoxy-kuleyl ah (resin epoxy silver-doped) oo ku yaal dusha sare ee substrate-ka. Kadibna chip-ka LED-ka waxaa lagu dhejiyaa substrate-ka isku xira ee leh koollada korantada ama kuwa aan fiicneyn iyada oo loo marayo koollada ama alxanka, iyo ugu dambeyntii isku xirka korantada ee u dhexeeya chip-ka iyo PCB-ga waxaa lagu gartaa silig (silig dahab ah).
