Gulu B epoxy fiberglass laminate(omwe amadziwika kutiG10) ndi FR-4 ndi zida ziwiri zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo zimakhala ndi magetsi komanso makina abwino kwambiri. Ngakhale amawoneka ofanana, pali kusiyana kwakukulu pakati pa awiriwa.

G10ndi high-voltage fiberglass laminate yomwe imadziwika ndi mphamvu zake zambiri, mayamwidwe ochepa a chinyezi komanso zinthu zabwino kwambiri zotchinjiriza magetsi. Nthawi zambiri amagwiritsidwa ntchito pamakina omwe amafunikira mphamvu zamakina apamwamba komanso kutchinjiriza kwamagetsi kwabwino, monga mapanelo otchingira magetsi, midadada yama terminal ndi zida zamakina pazida zamagetsi.

FR-4, kumbali ina, ndi kalasi yoletsa motoG10. Amapangidwa ndi nsalu ya fiberglass yolukidwa ndi zomatira za epoxy resin ndipo imakhala ndi mphamvu zabwino kwambiri zotchinjiriza magetsi komanso kuchedwa kwamoto. FR-4 imagwiritsidwa ntchito kwambiri pama board osindikizira (PCBs) ndi zida zina zamagetsi zomwe zimafuna kuchedwa kwamoto komanso mphamvu zamakina apamwamba.

Kusiyana kwakukulu pakati pa G10 ndi FR-4 ndi katundu wawo woletsa moto. Ngakhale G10 ili ndi mphamvu zamakina apamwamba komanso kutsekereza kwamagetsi, sikuti imakhala yoletsa moto. Mosiyana ndi zimenezi, FR-4 imapangidwa makamaka kuti ikhale yochepetsera moto komanso yozimitsa yokha, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kumene chitetezo cha moto chimakhala chodetsa nkhaŵa.

Kusiyana kwina ndi mtundu.G10nthawi zambiri imapezeka mumitundu yosiyanasiyana, pomwe FR-4 nthawi zambiri imakhala yobiriwira chifukwa cha kupezeka kwa zowonjezera zamoto.

Pankhani ya magwiridwe antchito, onse a G10 ndi FR-4 ali ndi kukhazikika kwabwino kwambiri, mphamvu zamakina apamwamba komanso zida zabwino zotchinjiriza magetsi. Komabe, zikafika pamapulogalamu omwe ali ndi zofunika zolimba pakubweza kwa lawi, FR-4 ndiye chisankho choyamba.

Mwachidule, pamene G10 ndi FR-4 amagawana zofanana zambiri pakupanga ndi machitidwe, kusiyana kwakukulu kuli muzinthu zoletsa moto ndi mtundu. Kumvetsetsa kusiyana kumeneku n'kofunika kwambiri posankha zinthu zoyenera pa ntchito inayake, kuonetsetsa kuti ntchito yabwino ndi yotetezeka.
