Le yi-PCB eyi-2 alumimum PCB yomkhakha we-LED. Ibhodi Yesekethe Eliphrintiwe Lensimbi (i-MCPCB), noma i-PCB eshisayo, luhlobo lwe-PCB olunempahla yensimbi njengesisekelo salo sokusabalalisa ukushisa kwebhodi. Inhloso yengqikithi ye-MCPCB ukuqondisa kabusha ukushisa kude nezakhi zebhodi ezibucayi nezindawo ezingabalulekile kangako njengokusekelwa nge-heatsink yensimbi noma umnyombo wensimbi. Izinsimbi eziyisisekelo ku-MCPCB zisetshenziswa njengenye indlela yamabhodi we-FR4 noma we-CEM3.
