发明名称 Flexible circuit substrate for flip-chip-on-flex applications
摘要 A circuit substrate for attachment to an integrated circuit chip comprises an electrical trace, a mounting pad and a dielectric layer. The mounting pad has a first surface, one or more sidewalls and a second surface. The first surface is attached to the electrical trace. The dielectric layer substantially covers the one or more sidewalls of the mounting pad and has an uppermost surface that is substantially coplanar with the second surface of the mounting pad.
