    Abstract: An impedance-matching electrical connection system, for use with high-frequency communication signals, includes a circuit board and a plurality of contact pads mounted on the circuit board. The contact pads are for coupling with a plurality of complementary connectors of an external electrical device. Each coupling is associated with an excess shunt capacitance. The electrical connection system further includes a plurality of inductive traces mounted on the circuit board, each of which is connected to a respective contact pad, and is associated with a compensating series inductance. Additionally, the electrical connection system includes a plurality of signal lines mounted on the circuit board, each of which is connected to a respective inductive trace. Each inductive trace is configured so that its associated compensating series inductance substantially offsets the excess shunt capacitance associated with the coupling between the contact pad connected to the inductive trace and a complementary connector.

    Abstract: A thin flexible electric conductor for use in implantable devices such as cochlear implants, consists of a conductive metal layer coated on a flexible three dimensionally textured surface so that the current capacity of the conductor is increased relative to the current capacity of a conductor of the same size that is not on a three dimensional surface. The flexible substrate is treated to form a three dimensional surface such as with corrugations and a conductive layer is deposited onto the surface.

    Abstract: A bonded structure comprising a board provided with a through hole, a land disposed on the periphery of the through hole, and a lead led out from an electronic part and placed in the through hole. The land comprises an wall face land part on the wall face of the through hole, and front and rear surface land parts on the front and rear surfaces of the board. A fillet for connecting the land with the lead comprises upper and lower fillets parts touching the front and rear surface land parts, respectively, wherein the contour of the upper fillet is smaller than the contour of the lower fillet but larger than the size of the through hole. When a lead-free solder material is employed, occurrence of liftoff can be reduced effectively as compared with a conventional one.

    Abstract: The invention relates to a method for fixing an especially modularly mounted, miniaturised component (2) onto a base plate (1) by means of a soldered joint. One side (4) of the component (2) is coated with a layer (5) of soldering material and the base plate (1) is coated at least partially with a layer of metal (6, 6', 6''). The component (2) is positioned above the base plate (1) with the metal layer and the layer of soldering material (5) facing each other without touching, at a vertical distance from each other. Heat energy is then supplied from the side of the base plate (1) in order to melt the soldering material of the soldering material layer (5) on the side (4) of the component (2) until a drop is formed. The component (2) and the base plate (1) are mutually fixed to each other when the drop of soldering material (5') fills the gap between them.
