The development of the technique for manufacture round copper wire coated with "tin-lead" alloy is considered. optimal parameters such as temperature melt, linear speed tinning a and diameter diamond die were determined. test results experimental samples are presented.

Diamond wires are high-speed, efficient and cost-effective stone cutting tools used both in quarries, to obtain large blocks, block-processing plants, shape ornamental stones. generally composed by a wire rope with evenly spaced diamond beads fixed polymer or rubber coating. A numerical model of the was developed Abaqus™ software aiming study damage failure steel during process. The is intended...

Each of two detectors used in our Positron Emission Mammography (PEM) system consists of four 36 mm x 36 mm x 20 mm bismuth germanate (BGO) crystal detector blocks coupled to a crossed-wire anode position-sensitive photomultiplier tube (PS-PMT). To facilitate high spatial-resolution imaging, the crystal blocks have been finely pixelated using a diamond saw. In each detector, 36 x 36 1.9 mm x 1....

INSTRUCTIONS The diameter of silicon wafer becomes larger in order to increase the number of chips per one wafer. For such a larger diameter silicon ingot is mainly sliced by using multi-wire method, in which a long thin wire is used with slurry. In this method, several hundreds of wafers could be sliced at the same time. However there are still problems remained, such as large cracks, slurry t...

We have investigated the electromagnetic properties of a 3D wire mesh in a geometry resembling covalently bonded diamond. The frequency and wave vector dispersion show forbidden bands at those frequencies n0, corresponding to the lattice spacing, just as dielectric photonic crystals do. But they have a new forbidden band which commences at zero frequency and extends, in our geometry, to , 12 n0...

Due to the brittleness of silicon, use a diamond wire cut silicon wafers is critical stage in solar cell manufacturing. In order improve production yield cutting process, it necessary have thorough understanding phenomena relating parameters. This research reviews and summarizes technology for precision machining monocrystalline using sawing (DWS). Firstly, mathematical models, molecular dynami...
