  • Two Solutions to Static Problems in Semiconductor Die Bonder Operation (.pdf)
    One phase of the semiconductor manufacturing process involves a die bonding machine. Several manufactures produce this type of equipment, with similar designs for the actual bonding operation. A fine gold wire (approximately 2 mil. In diameter) is attached from the semiconductor component
  • Diode Chips, Beam-Lead Diodes, Capacitors: Bonding Methods and Packaging
    on a. clean, hard surface such as a microscope slide. It is recom-. mended that the beam side of the device be down so that this. Equipment. side will be toward the substrate when bonded. The device can. Equipment for die attachment and lead bonding is commercially. be picked up by pressing lightly
  • Spin-Coating Waferbumping Fluxes for Semiconductor Assembly: Ensuring Pristine Microbumps in Dimensional Devices
    As semiconductor nodes and die shrink, the. number of I/Os will either increase or. remain relatively constant, leading to a. need for finer pitches. With device-device. interconnect pitches shrinking below the. 100micron level, plated copper pillars with. plated solder microbumps have supplanted
  • The Drive to Miniaturize - 0201 Flip Chip Silicon Schottky Diodes
    The incessant drive to. miniaturize electronic. systems places pressure. on semiconductor manufacturers. to offer ever-smaller components. This trend is rapidly. approaching its logical conclusion,. which is the elimination. of the semiconductor's package. altogether in favor of a die. which can
  • Medical Device Link .
    are simultaneously shaped and are terminated to each die pad. Following inspection, the die units are each encapsulated with a high-grade dielectric compound. Figure 2. A three-die uZ folded package outline is only slightly larger than the largest die in the set. (click to enlarge). The folding and bonding
  • Global Solar Technology - Smart packages for CPV cell devices
    , with some smart design,. be developed to utilise much of. the manufacturing technologies. that have recently mushroomed. for the fast growing LED. industry. The small compound. semiconductor solar cells can. be manufactured by using. optoelectronic semiconductor. assembly techniques (wire. bonding
  • Medical Device Link .
    to final assembly with confidence that the underfill would be dispersed completely, free of contaminants and voids (see photo). Stud bumping is done by machine wire bonding, leaving gold bumps called single ball bumps, or stud bumps, on the die pads. Stud bumping provides great versatility because
  • Medical Device Link . MEDTEC 98 Exhibitor Profiles
    . Converts nonsensitizing adhesive-coated papers, films, foils, nonwovens, foams, fabrics, and hydrogels. Manufacturing capabilities include flexographic printing, precision rotary and flatbed die-cutting, pattern adhesives, multilayer laminations, and island placement. Design, engineering, and prototype
  • Plastic Packaging and the Effects of Surface Mount Soldering Techniques
    . The. independent experimentation into this area. bending action of the strip is produced by unequal. Leadframes used by Microchip are copper with a silver. expansion on one side of the strip. As the strip cools, it. plated area for die attach and wire bonding. Die attach. will move back thus making
  • Isolator vs. Optocoupler Technology
    of light. Figure 2B shows the die configuration and bonding of a 150 Mbps, six-channel CMOS digital isolator. The base isolator die is designed and fabricated such that wire-bonding two identical die together (Figure 2B) forms a transmitter and receiver separated by a differential capacitive isolation
