متن کاملWire bonding using copper wire
Purpose – This paper attempts to review recent advances in wire bonding using copper wire. Design/methodology/approach – Dozens of journal and conference articles published recently are reviewed. Findings – The problems/challenges such as wire open and short tail defects, poor bondability for stitch/wedge bonds, oxidation of Cu wire, strainhardening effects, and stiff wire on weak support struc...
متن کاملApplication of PIXE to the study of Renaissance style enamelled gold jewelry
This study examines and compares three pieces of Renaissance style gold and enamelled jewelry owned by the Walters Art Gallery, Baltimore, MD, USA. These are a 16th century Hat Badge of Adam and Eve, a 19th century Fortitude Pendant and a Diana Pendant presumed to be of the 16th century (The Walters Art Gallery, Jewelry, Ancient to Modern (Viking, New York, 1979)), Ref. [1]. PIXE spectroscopy w...
متن کاملCavity mode related wire breaking of the SPS Wire Scanners and loss measurements of wire materials
During the SPS high intensity run 2002 with LHC type beam, the breaking of several of the carbon wires in the wire scanners has been observed in their parking position. The observation of large changes in the wire resistivity and thermionic electron emission clearly indicated strong RF heating that was depending on the bunch length. A subsequent analysis in the laboratory, simulating the beam b...
متن کاملWire Polarizers
In 1861 Fizeau studied transmission of polarized light through a screen with subwavelength scratches [1], and in 1888 Hertz performed similar experiments with radio waves and a grid of wires, which transmited polarized electromagnetic waves, of wavelength λ large compared to the wire spacing d, only if the electric field of the wave was perpendicular to the direction of the wires. Explain these...
