Abstract:
An objective is to provide an automatic cleaning device for machine tool in which cleaning efficiency is improved by performing cleaning for a large range during machining. To achieve this, an air nozzle (21) that removes, by air-blowing, chips (Wa) and cutting oil (C) dispersed while a workpiece is being machined to an outside of the machine is allowed to move not only independently from a movement of a spindle head (16), but also relatively to a workpiece (W) in directions of three orthogonal axes.
Abstract:
A wiring board includes: a flexible insulating base 1; a plurality of conductive wirings 2 arranged on the flexible insulating base 1; protruding electrodes 3 provided respectively at an end portion of the same side of each of the conductive wirings; external terminals 4, 5 formed respectively at the other end portions of each of the conductive wirings; metal plating layers applied on the conductive wirings, the protruding electrodes and the external terminals; and solder resist layers 7 formed respectively by coating the conductive wirings in regions between the end portions at which the protruding electrodes are provided and the external terminals. In the regions where the solder resist layers are formed, no metal plating layers are formed on the conductive wirings, and the surfaces of the conductive wirings to be contacted with the flexible insulating base are rougher than the surfaces not to be contacted with the flexible insulating base. Even when a film base is thin, bending stress applied to the conductive wirings is relieved sufficiently, and thus breaks in the wirings are suppressed.
Abstract:
A flexible insulating base, a plurality of conductor wirings aligned on the flexible insulating base, and bump electrodes provided respectively in end portions of the plurality of conductor wirings in a region where a semiconductor chip is to be placed are provided. The semiconductor chip is mounted on the conductor wirings by bonding electrode pads formed on the semiconductor chip to the bump electrodes. An auxiliary conductor wiring formed similarly to the conductor wirings is provided on the insulating base, and an auxiliary bump electrode formed similarly to the bump electrodes is provided on the auxiliary conductor wiring, so that the electrode pads formed on the semiconductor chip can be registered with respect to the bump electrodes on the conductor wirings by positioning the semiconductor chip with reference to the auxiliary bump electrode. It is possible to configure a wiring board having register marks capable of positioning electrode pads of a semiconductor chip with respect to bump electrodes with high accuracy.
Abstract:
A flexible insulating base, a plurality of conductor wirings provided on the base, and a plurality of bump electrodes that are formed on the plurality of conductor wirings, respectively, are provided. A semiconductor chip having electrode pads is to be mounted by placing the semiconductor chip on the bump electrodes and bonding the electrode pads and the bump electrodes, respectively. The bump electrodes are placed on the conductor wirings, respectively, in edge portions of at least two sides of a chip mounting region in which the semiconductor chip is to be mounted. The conductor wiring corresponding to at least one of the bump electrodes placed in the edge portions of the two sides passes through the chip mounting region so as to be routed via a side different from the side on which the at least one of the bump electrodes is placed, and then led to an outside of the chip mounting region. It is possible to route wirings more freely for leading conductor wirings from bump electrodes placed in an edge portion of a semiconductor chip mounting region to an outside of the chip mounting region.

A semiconductor device in accordance with the present invention is a mounted body of a semiconductor chip with a plurality of electrode pads arranged in a plurality of stages and a tape wiring board, the average pitch of the electrode pads on the entire semiconductor chip can be reduced, while ensuring stable connectivity, by leading together to the outside of the semiconductor chip two or more wirings of the tape wiring board connected to the electrode pads on the inner side between the electrode pads arranged in a row on the outer periphery of the semiconductor chip.
Abstract:
A spool of a lock-up control valve is arranged to have equal pressure differential areas exposed to the apply and release pressures applied to the apply and release chambers of the lock-up clutch. The movement of the spool is determined by changes in a single variable level pressure and independent of the apply pressure.
