Tus tsim ntawm PC LEDs, los yog phosphor-hloov LEDs
Feem ntau, nto-mount PLCC hom pob yog siv rau nruab nrab lub zog LEDs. PLCC, los yog yas leaded nti cab kuj, yog ib tug luv luv. Ib los yog ntau tshaj semiconductor chips (los yog tuag) yog sib koom los yog soldered mus rau ib tug hlau ncej los tsim ib tug nto-mount ntaus ntawv (SMD). Cov ncej txhuas, uas yog npaj los muab kev sib txuas hluav taws xob, thermal dissipation, thiab lub teeb pom kev zoo rau LED tuag, yog tsim los ntawm tooj liab alloy lossis npib tsib xee hlau alloy. Txhawm rau kom muaj hluav taws xob conductivity thiab muab lub teeb pom kev zoo, nws yog plated nrog nyiaj, kub, lossis lwm yam hlau. Hlau bonding yog siv los txuas cov anode thiab cathode ua rau qhov zoo thiab tsis zoo electrodes ntawm LED tuag, feem. Vim hais tias feem ntau ntawm cov hluav taws xob nruab nrab ntawm LEDs tau tsim nrog anode thiab cathode pads ntawm lub hauv paus ntawm lub pob es tsis yog cov qauv coj ua raws li ib puag ncig, niaj hnub mid-power LEDs tseem hu ua Quad Flat No-lead (QFN) pob. Cov hlau lead yog molded nyob rau hauv ib lub tsev yas thaum lub sij hawm kawg ntawm kev ntim khoom, tsim ib qho hollow. Cov epoxy resin los yog silicone-raws li polymer siv los sau cov kab noj hniav yog phosphor encapsulation matrix. Muaj ntau ntau yam sib txawv rau SMD LEDs. Qhov ntau thiab tsawg yog 2835 (3.5 x 2.8 mm) thiab 3030 (3.0 x 3.0 mm), nrog rau lwm qhov ntau thiab tsawg xws li 5630 (5.6 x 3.0 mm) thiab 3014 (3.0 x 1.4 mm) tau siv rau hauv cov ntawv tshwj xeeb.
