Ngokwenani lemigca ye-PCB, yahlulahlulwe yangamacala odwa, enamacala amabini, kunye neeBhodi zemibalabala. Iinkqubo ezintathu zebhodi azifani.

Akukho nkqubo yangaphakathi ye-LARHER yephaneli enamacala amabini kunye ne-upender, ngokusisiseko-ngokusisiseko-uqhushululu-up.
Iibhodi ze-Multilayer ziya kuba neenkqubo zangaphakathi

I-1) inkqubo yepaneli enye yokuhamba
Ukusika kunye nokugqobhoza → Ukuntywila

2) Inkqubo yokuhamba kwe-tin ye-tin ephindwe kabini
Ukusika umphetho ogada → Ukucutha

I-3) I-Spake ye-pikel ye-nickel-golide
Ukusika umphetho ukugaya → Ukucutha

I-4) inkqubo yokuhamba kweBhodi yeBhodi yeBhodi yeBin ye-Tin
Ukusika kunye nokugaya → Ukugqobhoza imingxunya Inqanaba lokufaka

I-5) Inkqubo yokuhamba kwe-nickel-igolide yegolide kwiBhodi yeZilayidi
Ukusika kunye nokugaya → Ukugqobhoza imingxunya Ukuqhubekeka → Uvavanyo → uhlolo

I-6) Inkqubo yokuhamba kwe-Prote-Sletery Pleate incleion ickel-yegolide
Ukusika kunye nokugaya → Ukugqobhoza imingxunya Igolide → Iimpawu zesibhakabhaka
