Highly integrated electronic circuit, especially for using in heart stimulators

摘要

The circuit has flexible substrate (1) with a component side (2) and insulated rear side (14). Both active and passive electronic components (5) are affixed to contact surfaces (4) of substrate which is then folded together along fold region (11). The section with components on both sides of the fold lie parallel and near each other. The flexible substrate (1) is folded so that the side of the substrate with component sides are turned towards each other. The passive rear side (14) of the substrate forms the insulation from the housing and other components of the pacemaker. The fold section (11) is at the middle of the substrate surface area so that the circuit forms a U-shaped configuration. An insulation layer is laid between the sections (12,13) of the substrate and the substrate has a one piece affixed flexible connector strap (6) to connect to external components (7)
