Ibikoresho bya PCB FR4 biraboneka muri TG yo hagati (ubushyuhe bwikirahure bwo hagati) hamwe na TG yo hejuru (ubushyuhe bwo hejuru bwikirahure).
TG bivuga ubushyuhe bwikirahure, ni ukuvuga kuri ubu bushyuhe, urupapuro rwa FR4 ruzahinduka muburyo bwimiterere, bikavamo impinduka mumiterere yibintu.Ubushyuhe bwikirahure bwimpapuro za TG zisanzwe muri dogere selisiyusi 130-140, mugihe ubushyuhe bwikirahure bwimpapuro za TG ziri hejuru ya dogere selisiyusi 150.Amabati maremare ya TG afite umutekano muke hamwe nubushyuhe bwo hejuru, kandi birakwiriye kubisabwa bigomba guhangana nubushyuhe bwo hejuru, nka electronics yimodoka, kugenzura inganda, ikirere nizindi nzego.Impapuro zo hagati za TG zirakwiriye cyane kubicuruzwa rusange bya elegitoroniki nibikoresho byitumanaho nibindi bice.
Guhitamo icyiciro gikwiye biterwa nibisabwa hamwe nibidukikije mubisabwa byihariye.
