Abstract:
A microwave or radio frequency (RF) device (300) includes stacked printed circuit boards (102, 152) (PCBs) mounted on a flexible PCB (206) having at least one ground plane and a signal terminal. Each of the stacked PCBs includes through-holes (120) the sidewalls of which are coated with a conductive material. Microwave components (110, 112, 154, 156) are mounted on the flexible PCB within the through-holes, such that signal terminals of the components bond to respective signal terminals of the flexible PCB. A conductive cover (132, 228) is mounted on the PCBs such that the cover is in electrical contact with the ground plane of the flexible PCB through the conductive material, forming shielding cavities around the components. The flexible PCB is folded such that the cover (132) of one PCB faces the cover (228) of the second PCB. The flexible PCB includes striplines or microstrips that carry RF or microwave signals to the signal terminals.

Abstract:
According to one aspect, the invention provides a method of providing conductive structures between two foils in a multi-foil system. The system comprises at least two foils, from which at least one foil comprises a terminal. The method comprises the steps of (in any order) providing at least one solid state adhesive layer, patterning adhesive layer with through-holes; filling the through-holes with conductive material, so as to form the conductive structure, connected to the terminal; and bonding the at least two foils. One advantage of the invention is that it may be used in a manufacturing process for multi-foil systems.
