Ngenxa yezici zesakhiwo somugqa wesibani se-COB, indawo ekhanyayo iyi-colloid eqondile;Futhi ibhande lesibani sohlobo lwesibani esivamile, isakhiwo salo siwuhlalu lwesibani olukhanyayo, olunamathiselwe ebhodini le-PCB.Ngakho-ke ukukhanya okuvela kumugqa we-COB kufana kakhulu, kumugqa, akukho mabala;
I-COB chip igxilwe ngokuqondile ebhodini le-PCB, ukushisa kwe-chip kungadluliselwa ngokushesha ebhodini le-PCB.Ngakho-ke, izinga lokukhipha ukushisa kwe-chip yomugqa wesibani se-COB liyashesha kunelambu lobuhlalu, futhi ukubola kokukhanya komugqa wesibani se-COB kuncane futhi impilo yinde.
I-engeli ekhanyayo yomugqa wesibani we-COB ingafinyelela ku-180 °.
