Kusiyana pakati pa SMD ndi COB encapsulation

Kuwala kwa LED kwa SMD ndi COB kutsogola kumapezeka ku Lediant. Kodi mukudziwa kusiyana kwawo? Ndiroleni ndikuuzeni.

Kodi SMD ndi chiyani? Zikutanthauza zipangizo zokwera pamwamba. The LED ma CD fakitale ntchito ndondomeko SMD kukonza anabala Chip pa bulaketi, magetsi zikugwirizana awiri ndi mawaya golide, ndipo potsiriza amateteza ndi epoxy resin.SMD ntchito pamwamba phiri luso (SMT), amene ali ndi digiri yapamwamba ya zochita zokha, ndipo ali ndi ubwino wa kukula kwazing'ono, ngodya yaikulu kumwazikana, zabwino zowala yunifolomu, ndi kudalirika mkulu.

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.
