PRINTED CIRCUIT BOARD WITH INTEGRATED THIN FILM BATTERY

摘要

The present invention relates to, for example, printed circuit boards having a thin film battery or other electrochemical cell between or within its layer or layers. The present invention also relates to, for example, electrochemical cells within a layer stack of a printed circuit board.

主权项

1. A printed circuit board comprising:
a printed circuit board (PCB) layer stack having a plurality of layers which include two outer electrically insulating layers, with conductor traces being formed on one or both of said two outer electrically insulating layers; wherein each of the two outer electrically insulating layers of the PCB layer stack comprises an insulator material disposed in an epoxy material; an electrochemical cell inserted in said PCB layer stack between said two outer electrically insulating layers of the PCB layer stack, wherein said electrochemical cell is embedded between said two outer electrically insulating layers of said PCB layer stack; a spacer between the two outer electrically insulating layers; and a gap of space located at an edge of said electrochemical cell, the gap of space defined by the spacer, said electrochemical cell and at least one of the two outer electrically insulating layers.
