E tusa ai ma le numera o laupepa PCB, ua vaevaeina i le tasi itu, lua itu, ma le tele-laupapa laupapa.E le tutusa le faiga o le laupapa e tolu.

E leai se faiga fa'avae i totonu mo panels e tasi-itu ma lua-itu, fa'avae tipi-lili-mulimuli.
O laupapa multilayer o le ai ai faiga faʻalotoifale

1) Fa'asologa o le fa'agasologa o le laulau e tasi
Otiotiina ma fa'ai'uga → viliina → fa'ata'ita'iga pito i fafo → (fa'apipi'i auro atoa) → togitogi → su'esu'ega → ufimata solder silk screen → (fa'asa'oina o le ea vevela) → mata'itusi mata siliki → fa'asologa o foliga → su'ega → asiasiga

2) Fa'agasologa fa'agasologa ole laupapa fa'apa apa e lua itu
vili mata → viliina → mafiafia apamemea mamafa → ata o le pito i fafo → ufi apa, aveese apa → vili lona lua → asiasiga → lomitusi mata solder ufimata → palaka auro → ea vevela → mataitusi mata siliki → suʻega foliga → suʻega → suʻega

3) Fa'asagaga fa'apipi'i nikeli-auro e lua itu
Oli pito pito → viliina → mafiafia kopa mamafa → faʻataʻitaʻiga pito i fafo → faʻapipiʻi nickel, aveese auro ma togitogi → vili lona lua → asiasia → mata siliki solder ufimata → mata siliki mata → faʻasologa o foliga → suʻega → asiasiga

4) Fa'agasologa fa'agasologa ole laupapa fa'alava fa'apipi'i apa laupapa
Otioti ma olo → viliina pu → faʻataʻitaʻiga i totonu → faʻapipiʻi pito i totonu → suʻesuʻega → uliuli → lamination → viliina → mafiafia kopa mamafa → faʻataʻitaʻiga pito i fafo → faʻapipiʻi apa, aveese apa apa → vili lona lua → asiasia → mata solder mata silika → auro -palapala fa'apipi'i → Fa'ata'atiaga o le ea vevela → Fa'ailoga mata silika → Fa'asologa o foliga → Su'ega → Asiasiga

5) Fa'agasologa fa'agasologa ole fa'apipi'i nickel-auro i luga o laupapa fa'apipi'i
Otioti ma olo → viliina pu → faʻataʻitaʻiga i totonu → faʻapipiʻi pito i totonu → suʻesuʻega → uliuli → lamination → viliina → mafiafia kopa mamafa → ata pito i fafo → faʻapipiʻi auro, aveese ata ma togitogi → vili lona lua → asiasiga → ufimata solder lomitusi → mataitusi lolomi lau → faʻasologa o foliga → suʻega → asiasiga

6) Fa'agasologa fa'agasologa o ipu fa'aulu fa'atofuina ipu nickel-auro
Otioti ma olo → viliina pu → faʻataʻitaʻiga i totonu → faʻapipiʻi pito i totonu → asiasia → faʻauliuli → lamination → viliina → mafiafia kopa mamafa → faʻataʻitaʻiga pito i fafo → faʻapipiʻi apa, aveese apa apa → vili lona lua → asiasiga → ufimata solder mata silika → kemisi Fa'atofuina Nikeli Auro → Mataitusi mata silika → Fa'asologa o foliga → Su'ega → Su'esu'ega.
