Ngenxa yeempawu zesakhiwo somgca wesibane se-COB, i-luminescent surface yi-colloid yomgca;Kwaye ibhanti yesibane yohlobo lwesibane eqhelekileyo, ubume baso busisibane esikhanyayo, sincanyathiselwe kwibhodi yePCB.Ke ukukhanya okuvela kumcu weCOB kufana kakhulu, kumgca, akukho mabala;
I-COB chip igxininiswe ngokuthe ngqo kwibhodi ye-PCB, ukushisa kwe-chip kunokudluliselwa ngokukhawuleza kwibhodi ye-PCB.Ke ngoko, ubushushu bobushushu be-chip yesibane sesibane se-COB bukhawuleza kuneso sibane sesibane, kwaye ukubola kokukhanya komtya wesibane we-COB kuncinci kwaye ubomi bude.
I-Angle ekhanyayo yesibane sesibane se-COB inokufikelela kwi-180 °.
