Ose maviri SMD akatungamira kudzika uye COB akatungamira kudzika anowanikwa muLediant. Unoziva here musiyano uripo pakati pavo? Rega ndikuudze.
Chii chinonzi SMD? Zvinoreva pamusoro akaiswa midziyo. Iyo LED yekurongedza fekitori inoshandisa iyo SMD process inogadzirisa iyo isina chip pabhuraketi, nemagetsi inobatanidza maviri newaya dzegoridhe, uye pakupedzisira inoidzivirira ne epoxy resin.SMD inoshandisa surface mount tekinoroji (SMT), iyo ine dhigirii rakati wandei re automation, uye ine zvakanakira saizi diki, hombe yekuparadzira kona, yakanaka inopenya kufanana, uye yakakwirira kuvimbika.
Chii chinonzi COB? Zvinoreva chip pabhodhi. Kusiyana neSMD, iyo inotengesa marambi kuPCB, maitiro eCOB anotanga kuvhara nzvimbo yekuisa iyo silicon chip ine thermally conductive epoxy resin (silver-doped epoxy resin) pamusoro peiyo substrate. Ipapo iyo LED chip inonamatira kune yekubatanidza substrate ine conductive kana isiri-conductive guruu kuburikidza nekunamira kana solder, uye pakupedzisira iyo yemagetsi yekubatanidza pakati chip nePCB inowanikwa newaya (yegoridhe waya) bonding.
