Patent ID: 6950312

Claim:
A method to package electrical units comprising: providing a plurality of planar electronic circuit boards; providing a cover element with defined folding points therein wherein said cover element being electrically non-conductive and free of electrical components; connecting the plurality of planar electronic circuit boards with an electrical conductive member over which electrical signals between boards are being transmitted; placing a first planar electronic circuit board with its bottom side at a first part of said cover element; folding said cover element at a defined folding point and placing a first remaining part of said cover element upon the surface of the top side of said first planar board thereby covering the side surface of the first planar board; placing a second planar board with its bottom side seated on said surface of the first remaining part of said cover element; and folding another remaining part of said cover element at a further defined point and placing the remaining part of said cover element upon the surface of the top side of said second planar board thereby covering the side surface of said second planar board.
