Ka bobeli SMD led led lightlight le COB led LED li fumaneha Lediant. Na u tseba phapang pakeng tsa tsona? E-re ke u bolelle.
SMD ke eng? E bolela lisebelisoa tse behiloeng holim'a metsi. Fektheri ea ho kenya lisebelisoa tsa LED e sebelisang mokhoa oa SMD e lokisa chip e se nang letho ka har'a bracket, e kopanya ka motlakase tse peli le lithapo tsa khauta, 'me qetellong e li sireletsa ka epoxy resin.SMD e sebelisa theknoloji ea holim'a metsi (SMT), e nang le tekanyo e batlang e phahame ea ho iketsetsa,' me e na le melemo ea boholo bo bonyenyane, angle e kholo ea ho hasanya, ho tšoana hantle ho khanyang, le ho tšepahala ho phahameng.
COB ke eng? E bolela chip ka sekepeng. Ho fapana le SMD, e rekisang lifaha tsa lebone ho PCB, ts'ebetso ea COB e qala ka ho koahela sebaka sa ho beoa ha silicon chip e nang le thermally conductive epoxy resin (silver-doped epoxy resin) holim'a substrate. Ebe LED chip e khomaretse substrate interconnection le conductive kapa non-conductive sekhomaretsi ka sekgomaretsi kapa solder, 'me qetellong ea motlakase interconnection pakeng tsa chip le PCB e hlokomela ka terata (terata khauta) bonding.
