Claim of US Patent No. 9,860,972

1. An electrical connection interface for electrically coupling a printed circuit board to an electro-optical engine, the
electrical connection interface comprising:
a first ground plane layer associated with the printed circuit board;
a second ground plane layer associated with the electro-optical engine;
a first substrate associated with the printed circuit board, the first substrate having a first substrate conductive lead
with a first interface region connected to and electrically insulated from the first ground plane layer; and

a second substrate associated with the electro-optical engine, the second substrate having a second substrate conductive lead
with a second interface region connected to the first interface region of the first substrate conductive lead, the second
substrate conductive lead connected to and electrically insulated from the second ground plane layer;

wherein the second ground plane layer associated with the electro-optical engine includes clearance; and
wherein the first ground plane layer overlaps the second ground plane layer and a dimension of the clearance corresponds to
a distance that the first ground plane layer overlaps the second ground plane layer.
