    摘要： A process and apparatus for preparing an MCM for hat removal where the hat includes a piston thermally coupled to a corresponding chip. The apparatus includes a heater positioned to reflow a joint between the piston and a base of the hat; and a retractor for biasing the piston away from the corresponding chip. Implementation of the apparatus and process prevent a piston, as it moves across the top of a corresponding chip during mechanical shear to remove the hat, to impact chip(s) and surrounding components. In addition, since piston(s) are retracted, the likelihood of piston impact with or cracking of a chip is reduced. In addition, cutting into a corresponding chip having a tilted back surface is prevented. The need to replace chips and other electronic components when making other repairs may, therefore, be greatly reduced.

    摘要： A magnetic head slider with at least one thin-film magnetic head element on a suspension is mounted. This mounting includes electrically connecting the magnetic head slider with the suspension with ball bonding connections. Electrical property of the thin-film magnetic head element is inspected, and then the ball bonding connections are separated when it is judged that the thin-film magnetic head element has defective electrical property. Then, the magnetic head slider is detached from the suspension, and thereafter a new magnetic head slider with at least one thin-film magnetic head element is mounted on the suspension from which the magnetic head slider was detached.

    摘要： A gas turbine vane (1) is subject to distortion and wear during operation or repair which results in an increase in the spacing between successive vanes (6 and 7) which define nozzle gas flow areas (8 and 9). During refurbishment, the nozzle spacing must be returned to the original dimension to insure optimum turbine performance. A build up of alloy in the wear area is accomplished by controllably applying layers of a tape (12) of uniform thickness to the vane. The tape includes a mixture of a binder and an alloy powder, which is compatible with the substrate alloy, with the mixture formed into a sheet of uniform thickness and having an adhesive backing. After applying the tape in layers to a desired thickness, the vane is heated to a temperature at which the binder and adhesive decompose and the alloy in the tape diffusion bonds with the substrate alloy. Utilization of this process reduces the cost of refurbishing used turbine vanes and avoids hot forming or bending processes which could damage the vanes.
