An encapsulation is provided on a flexible printed circuit board, comprising a top and a bottom electrically insulating base film, a top electrically conductive metal layer over the top electrically insulating base film, and a bottom electrically conductive metal layer under the bottom electrically insulating base film. A printable lithium ion battery is fabricated in a cavity completely through the top and bottom base films wherein a top of the battery contacts the top electrically conductive metal layer and wherein a bottom of the battery contacts the bottom electrically conductive metal layer. An adhesive film is fabricated around the battery to seals it to the top and bottom electrically insulating base film and to seals the top electrically conductive metal layer to the bottom electrically conductive metal layer.

Method of direct embedding a lithium ion battery on a flexible printed circuit board

An integrated electro-optical circuit board comprises a first flexible substrate having a top side and a bottom side, at least one first optical circuit on the bottom side of the first flexible substrate connected to the top surface through a filled via, at least one first metal trace on the top side of the first flexible substrate, an optical adhesive layer connecting the bottom side of the first flexible substrate to a top side of a second flexible substrate, and at least one second metal trace on a bottom side of the second flexible substrate connected by a filled via through the second flexible substrate, the optical adhesive layer, and the first flexible substrate to the at least one first metal trace.

Integrated electro-optical flexible circuit board

A flexible printed circuit board with a lithium ion battery printed thereon is achieved. The flexible printed circuit board comprises a top and a bottom electrically insulating base film, a top electrically conductive metal layer over the top electrically insulating base film, and a bottom electrically conductive metal layer under the bottom electrically insulating base film. A printable lithium ion battery sits in a cavity completely through the top and bottom base films wherein a top of the battery contacts the top electrically conductive metal layer and wherein a bottom of the battery contacts the bottom electrically conductive metal layer. An adhesive film around the battery seals it to the top and bottom electrically insulating base film and seals the top electrically conductive metal layer to the bottom electrically conductive metal layer.
