End plate for a spinal fusion cage

A ferrite chip bead includes a ferrite substrate, a plurality of outer electrodes formed at opposite sides of the ferrite substrate, and a plurality of conductive leads each extending transversely through the ferrite substrate and having opposite ends protruded outwardly of opposite side surfaces of the ferrite substrate and connected to corresponding outer electrodes. Conductive leads are embedded in the ferrite substrate by introducing conductive leads in a central portion of a nozzle for extruding the ferrite substrate such that the conductive leads are embedded in the ferrite substrate being extruded, or by introducing conductive leads between ferrite substrate sheets being fed to be bonded together for forming the ferrite substrate such that the conductive leads are interposed between the ferrite substrate sheets being bonded. The ferrite chip has no tendency for outer electrodes to short-circuit from the ferrite substrate upon carrying the chip bead on a circuit board. Manufacture is simplified and short circuits are prevented, thus enhancing reliability and productivity.

Ferrite chip bead and method for making same

A method for making a ferrite chip bead array in which a plurality of reinforcing outer electrodes are formed at the upper and lower surfaces of a ferrite substrate structure having a pair of substrate sheets and a plurality of uniformly spaced conductive leads interposed between the substrate sheets to enhance the bonding force between each electrode and each corresponding inner conductive lead, as well as the bonding force between each outer electrode and each corresponding inner conductive lead as well as the bonding force between each outer electrode and the ferrite substrate structure. The reinforcing outer electrodes eliminate a tendency for outer electrodes to short-circuit from the ferrite substrate upon placement of the chip bead array on a circuit board. The subject method simplifies manufacture and prevents short circuit, thereby enhancing reliability and productivity.
