摘要： An electrode tool for the electrochemical machining of metal components, such as the cavities of internal combustion engine valves, is adapted for mounting on a machine tool mandrel and comprises a shaft upon which a flexible, elongate electrode is axially slidable, and which defines axially a conduit for conveying electrolytic fluid to the workpiece. The working end of the tool is constituted by a releasable electrode guide head which defines a part-circularly-curved electrode guide passage and the end portions of the conduit. The guide passage guides the axial sliding of the electrode so that an end portion of the latter projects radially relative to the axis of the tool by an angle determined by the radius of curvature of the passage. The guide head is interchangeable with at least one other guide head having a passage with a different radius of curvature.

摘要： An ECM method involves the use of a thin hollow electrode assembly that carries the electrolyte within and that is advanced relatively to the workpiece. The small profile of the electrode results in a minimal removal of metal in forming the desired rotor or stator shape. The electrode profile allows significant power consumption reduction or increased machining speed for a given rate of power input. The electrode can be a unitary ring shape or can be made of segments that are placed adjacent each other so that a continuous shape is cut. Not all the lobes of the stator or rotor have to be cut in the same pass. Electrode segments can be used to sequentially provide the desired lobe count in separate passes. The lobe shapes in the electrode can be slanted to get the desired rotor or stator pitch or they can be aligned with the workpiece axis.

摘要： A semiconductor device having area array bump electrodes suitable for flip chip packaging is disclosed. A semiconductor chip with wire bonding electrodes arranged along peripheral edges thereof is provided, then gold wire bump electrodes are formed over the wire bonding electrodes, and thereafter a wiring tape substrate is superimposed on the semiconductor chip and is bonded thereto with an adhesive. On a back surface of the wiring tape substrate are formed wiring connections correspondingly to the electrodes. Further, at the time of bonding with use of the adhesive, convex tips of the gold wire bump electrodes formed respectively on the electrodes of the semiconductor chip pierce through the adhesive to connect the gold wire bump electrodes and the connections electrically with each other. On a surface of the wiring tape substrate are formed area array bump electrodes, whose pitch is larger than the pitch of the electrodes formed on the semiconductor chip.
