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. Feme ea liphutheloana tsa LED e sebelisang ts'ebetso ea SMD e lokisa chip e se nang letho ka har'a bracket, e hokahanya tse peli ka mehala ea khauta ka motlakase, 'me qetellong e e sireletsa ka epoxy resin. mme 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.
