Flexible electronic/optical interconnection film assembly and method for manufacturing
TLDR
In this article, a flexible electronic/optical interconnection film assembly which includes a flexible waveguide film laminated to a flexible electrical film, such as a flexible PCB, is presented.Abstract:
A flexible electronic/optical interconnection film assembly which includes a flexible waveguide film laminated to a flexible electrical film, such as a flexible PCB. The flexible waveguide film has embedded internal waveguide capable of total internal reflection such that optical transmission between two IC elements can be achieved through the use of laser diode transmitters and photodetector receivers. A flexible electrical film that is laminated to the flexible waveguide film may have a plurality of metal interconnect lines formed therein for providing electrical communication. A thin metal trace layer and a plurality of conductive pads which are formed from the thin metal trace layer may be formed on top of the flexible waveguide film for providing electrical communication with active opto-electronic devices mounted on top of the flexible waveguide film.read more
