Mea oloa
I le avea ai o se tagata e tuʻuina atu tekinolosi PCB eseese, voluma, taimi taʻitaʻia filifiliga, o loʻo i ai a matou filifiliga o mea masani e mafai ona ufiufi ai se bandwidth tele o ituaiga eseese o PCB ma o loʻo maua pea i totonu o le fale.
O mana'oga mo isi po'o mea fa'apitoa e mafai fo'i ona fa'amalieina i le tele o tulaga, peita'i, e fa'atatau i mana'oga tonu, e o'o atu ile 10 aso faigaluega e ono mana'omia e fa'atau ai mea.
Faʻafesoʻotaʻi ma matou ma talanoaina ou manaʻoga ma se tasi o matou faʻatau poʻo le CAM au.
Mea masani o lo'o teuina i fa'aputuga:

Fa'aputuga
A tulaga masani 8 layer PCB stackup o se laupapa 8 PCB.
E aofia ai le pito i fafo ma totonu o fa'ailoga fa'ailoga ma e tele fo'i vaega i totonu e puipuia ai fa'ailoga fela'ua'i.
Ole laulau ole 8 layer PCB stackup e fa'apea:
·Taaalo
· La'ei silika
· Solder masklayer
· Fa'ailoga fa'ailoga maualuga
· Fa'ailoga fa'ailoga
· Alavai
· Papa eleele
O lo'o iai le 7 fa'apalapala o le dielectric e fa'afeso'ota'i va'alele eleele se fa fa'ailoga fa'ailoga.
