A method of manufacturing a terminal-attached electric wire includes: installing an electric wire including a core wire including a plurality of element wires to a terminal having a conductor coupling part having a pair of barrel pieces, the core wire being installed between the pair of barrel pieces; bending the pair of barrel pieces to cause the pair of barrel pieces to wrap around and cover the core wire in a circumferential direction to form a slit extending in an axial direction between the pair of barrel pieces, with respect to the circumferential direction; melting the element wires of the core wire by emitting laser light toward the core wire through the slit; and adhering the element wires melted with the laser light to the conductor coupling part.

A manufacturing method of contact probes for a testing head comprises the steps of:—providing a substrate made of a conductive material; and—defining at least one contact probe by laser cutting the substrate. The method further includes at least one post-processing fine definition step of at least one end portion of the contact probe, that follows the step of defining the contact probe by laser cutting, the end portion being a portion including a contact tip or a contact head of the contact probe. The fine definition step does not involve a laser processing and includes geometrically defining the end portion of the contact probe with at least a substantially micrometric precision.

A method for welding a plurality of wire segment pairs is disclosed. Each wire segment pair has two adjacent wire segments, and each adjacent wire segment has a contact region where the wire segment is to be welded to the respective other wire segment. The wire segment pairs are successively guided between two elements of a pressing unit, and at a weld moment in which at least one of the wire segment pairs is located between the two elements. The pressing unit exerts a pressing force onto the wire segment pair such that the contact regions of the wire segments are pressed against each other. At each weld moment, laser radiation is irradiated onto the wire segment pair to which the pressing unit is exerting the pressing force, and the laser radiation is irradiated onto a region in which the contact regions are pressed against each other.

The present invention relates to a method for manufacturing a nonmagnetic water-cooled microwave ablation needle. The manufacturing method is designed for a microwave ablation needle of a nonmagnetic material and has a proper process procedure, favorable assembly quality, and high production efficiency. The produced nonmagnetic water-cooled microwave ablation needle is applicable to microwave tumor ablation surgery in a nuclear magnetic resonance imaging environment, and helps a doctor in charge to clearly determine a position of a tumor, improve piercing precision, have preferable control on a whole surgery process, improve a success rate of the surgery, reduce damage on surrounding normal tissues as much as possible on the premise of effectively inactivating the tumor, alleviate pain of a patient, and shorten a recovery cycle.

A method for producing a material that has the primary desirable properties that can be used for electrical terminal connectors. The present invention is directed at a clad material having high electrical conductivity, specific strength, good ductility, compatibility with joining materials, and low cost properties, and the method for making the material. In an aspect, the cladded material is made from one or more metals that collectively, have the properties discussed above. In an aspect, the cladded material is a transition-metal interconnector for electrical terminal connectors. In an exemplary aspect, the material is cladded aluminum and copper. The present invention relates to cladding materials built for use in connecting materials with different properties (e.g., aluminum and copper) in cathodes and anodes.

The invention relates to a device for welding rod-shaped conductors (14), comprising a compression chamber for receiving joining sections (13) of the conductors to be joined together, the compression chamber being limited in a first axial direction (z-axis) on two opposite sides by an active surface of a sonotrode (16) transmitting ultrasonic vibrations in the direction of the z-axis and by a counter surface of a counter electrode (18), the device having a knife device which is provided with a drive device and comprises a knife (24) movable in the direction of the z-axis, said knife having a cutting edge which can be moved past the compression chamber, wherein a drive motor of the drive device is arranged in an installation space arranged below the sonotrode, the drive motor being connected to a knife holder (26) via a deflection gear (31) in order for the knife to be able to perform a cutting motion, the knife being moveable in the direction of the z-axis.

A capacitor and methods of processing an anode metal foil are presented. The capacitor includes a housing, one or more anodes disposed within the housing, one or more cathodes disposed within the housing, one or more separators disposed between an adjacent anode and cathode, and an electrolyte disposed around the one or more anodes, one or more cathodes, and one or more separators within the housing. The one or more anodes each include a metal foil that includes a first plurality of tunnels through a thickness of the metal foil in a first ordered arrangement, the first ordered arrangement being a close packed hexagonal array arrangement, and having a first diameter, and a second plurality of tunnels through the thickness of the metal foil having a second ordered arrangement and a second diameter greater than the first diameter.

A material for Cu pillars is formed as cylindrical preforms in advance and connecting these cylindrical preforms to electrodes on a semiconductor chip to form Cu pillars. Due to this, it becomes possible to make the height/diameter ratio of the Cu pillars 2.0 or more. Since electroplating is not used, the time required for production of the Cu pillars is short and the productivity can be improved. Further, the height of the Cu pillars can be raised to 200 μm or more, so these are also preferable for moldunderfill. The components can be freely adjusted, so it is possible to easily design the alloy components to obtain highly reliable Cu pillars.
