Abstract:
1. A circuit board, comprising: an insulating material layer including a baseboard and a hardened insulating polymer layer; conductive patterns on both sides of the insulating material layer; at least one microcircuit comprising a first surface and having contact areas on the first surface, the at least one microcircuit being inside the insulating material layer in a hole in the baseboard and having the first surface against the hardened insulating polymer layer; conductive material on sidewalls of the hole in the baseboard, in order to create interference protection around the microcircuit; and contact openings in the hardened insulating polymer layer and copper in the contact openings for forming electrical contacts between the contact areas of the microcircuit and at least one of the conductive patterns, wherein the copper contains at least one of electrochemically deposited copper and chemically deposited copper.
