Polyimide Laminate
i3 Electronics, Inc.:
i3’s Polyimide is an industry standard GPY equivalent polyimide and is
used as a dielectric prepreg or a laminate in printed circuit board and
laminate chip carrier fabrication. This material exhibits excellent performance in the field in a variety of high end applications, and is an ideal
solution for the medical, aerospace and defense and computing markets.
i3’s polyimide is also lead free compatible.
