Abstract:
1. A method for manufacturing a flexible printed circuit, said method comprising: providing a plurality of optical waveguides for transmitting optical signals; constructing a first building block with a first dielectric layer adhered to a first substrate layer; constructing a second building block with a second dielectric layer adhered to a second substrate layer; forming a plurality of conductors for transmitting electrical signals by binding said first building block and said second building block via a first adhesive layer in which said plurality of optical waveguides are embedded; forming channels through said first and second building blocks to isolate at least one of said plurality of optical waveguides; and plating said channels with metal coatings to enclose said one of said plurality of optical waveguides by connecting said first substrate layer from said first building block to said second substrate layer from said second building block.
