Copper wire bonding has huge cost advantages over gold wire bonding. As a result, low pin count, heavy wire applications have already been converted to copper wire and many companies are in high volume production. Recently, with the price of gold skyrocketing, conversion of high pin count (>250 I/O), high performance applications to Cu has dramatically accelerated. These high performance device...

A method for bonding a niobium wire to a niobium thin film i s described The bonds are to be used as superconducting connections between wire-wound gradiometers and thin-film coupling coils on oc SOUIOS. The method is characterized by two steps. Firstly. the hardness of the niobium wire is reduced by a heat treatment. Secondly, the niobium film is covered with a thin layer of palladium to preve...

objective: thoracic trauma may be a life-threatening condition. flail chest is a severe chest injury with high mortality rates. surgery is not frequently performed and, in literature, data are controversial. the authors report their experience in the treatment of flail chest by an extracortical internal-external stabilization technique with kirshner’s wires (k-wires). methods: from 2010 to 2015...

in this study, polyaniline molecule (emeraldine base) is modeled as a molecular wire and the effects of the metal/molecule coupling strength and the molecule length on the current-voltage (i-v) characteristics are numerically investigated. using a tight-binding hamiltonian model, the methods based on non-equilibrium green’s function theory, landauer formalism and newns-anderson model, our calcu...

NiTi alloy wires are widely used in many applications for examples, orthodontic arch wires, mini screw implant, sensors, etc. Usually, wire drawing process is chosen to produce arch wires because of its high productivity as well as superior surface quality of the drawn wire surface. In the case of NITI arch wire, the cold work occurred during wire drawing operation also plays important role to ...

T.C. Fan*, F.Y. Lin, C.S. Hwang, Ian C. Hsu Synchrotron Radiation Research Center, Hsinchu, Taiwan National Tsing Hua University, Hsinchu, Taiwan Abstract Several laboratories have used the pulsed wire method for magnetic field measurement. The acoustic wave distortion of the wire was observed. The limitations of this method were discussed. A pulsed wire system is under test in SRRC on an undul...

When a load is added to the tip of a wire actuated robotic forceps, tracking accuracy of the forceps is degraded due to the elastic elongation of the wire. In this paper, for the wire actuated robotic forceps, a new algorithm that can estimate a reaction torque and an amount of elongation of the wire, is proposed. By compensating for amount of elongation of the wire, track ability of the forcep...

The progress in the design and development of small-scale computing devices to this date has established the possibility to integrate these computing devices into virtually all everyday objects. For the near future we expect the availability of even smaller and more densely integrated devices providing us with even more resources and computing power. Existing applications will benefit from this...
