Ka kakaretso,ts'ebetso ea tlhahiso ea lisebelisoa tsa elektroniki tsa PCB ke mosebetsi o rarahaneng le o hlokolosi o hlokang tšebelisano e haufi lipakeng tsa baenjiniere, baqapi le bahlahisi. Litlhoko tse thata tsa indasteri ea likoloi li hloka li-PCB tsa boleng bo holimo, tse tšepahalang le tse bolokehileng. Ha theknoloji e ntse e tsoela pele, li-PCB tsa elektroniki tsa likoloi li tla hloka ho fihlela tlhoko e ntseng e hola ea mesebetsi e rarahaneng le e rarahaneng. Ho lula ka pele ho sebaka sena se ntseng se fetoha ka potlako, baetsi ba PCB ba tlameha ho ikamahanya le mekhoa ea morao-rao. Ba hloka ho tsetela lits'ebetsong tse tsoetseng pele tsa tlhahiso le lisebelisoa ho netefatsa tlhahiso ea li-PCB tsa maemo a holimo. Ho sebelisa mekhoa ea boleng bo holimo ha ho ntlafatse boiphihlelo ba ho khanna feela, empa hape ho etelletsa pele polokeho le ho nepahala.
