Abstract: Method for welding two end portions (6, 8) of a coil (not shown) onto two electric contact pads or bumps (24, 26) of an integrated circuit (2) or an electronic unit of small dimensions. This welding method is characterised in that, prior to the actual welding step, a preliminary step is provided consisting in removing at least partially the insulating sheath from the electric wire (10) at least at the locations of the two end portions (6, 8) provided for the welding onto said electric contact pads or bumps (24, 26). The insulating sheath is removed locally by means of heat application, in particular using a heating press (58) working at a sufficiently high temperature to melt or sublimate the insulating sheath. The welding step is achieved at a much lower temperature than the temperature of the preliminary step, which allows the heat and mechanical stress to be reduced for the integrated circuit (2) and the bumps (24, 26) during welding of the ends (6, 8) onto said bumps.

Abstract: The present invention relates to a solder ball shaping tool and a method for using the tool. In a substrate there is formed a series of depressions. The tool is pressed onto a ball grid array and the ball grid array is realigned either with simple pressure or pressure assisted by heating. Where a solder ball may have been deposited upon a die or a chip package in a diameter that exceeds that of the designed diameter, a corral tool is used to substantially conform the solder ball to design dimensions and a design location. As the corral tool is pressed against the solder ball, portions of the solder ball will reflow both into the substrate depression and into the corral. Where the total volume of the solder ball does not exceed that of both the corral and the substrate depression, the corral tool is adequate to achieve a designed solder ball height.

Abstract: The thermal expansion of parts to be welded to each other is reduced in that one or more of the parts are modified to include expansion slots in the welding area. This limits thermal expansion to the remaining small areas only which are allowed to expand within the slots. Total expansion of such welded parts is thus reduced after solidfication. In most applications, such slots do not effect the total design of the welded parts. If required, such slots can be sealed after welding.

To prevent some inclination from arising between the bottom surface of the end element and the annular end surface of the pipe when they are tightly pressed against each other, the bottom surface is formed integrally with a plurality of rose seats of wedge shape in cross section that extend radially with respect to the axial center of the end element. Projection-welding is performed after the rose seats are brought into confronting contact with the tapered annular end surface of substantially triangular shape in cross section.

Abstract: A method is provided for use with non-contacting torque sensors. Many torque sensors use a sheet of magnetostrictive material wrapped about the shaft whose torque is to be measured. The methods used to wrap and affix the sheet of magnetostrictive material induce a prestress into the sheet, which leads to early saturation of the magnetostrictive material. The prestress diminishes the useful range of the torque sensor. As a solution, a method is provided for bonding a magnetostrictive material sheet to a shaft while minimizing stress of the magnetostrictive sheet. By bending a magnetostrictive material sheet and a carrier sheet about the mandrel and bonding the sheets together at a first preselected temperature, cooling them to form a cylinder having a magnetostrictive material outer layer and a carrier inner layer, and bonding the cylinder to a shaft at a second predetermined temperature, the stresses induced in the magnetostrictive sheet are minimized.

The alignment is done in this state.
