Application of Xenon Flash

The Xenon Flash devices are used in various applications. As the stroboscopes, they are used in universities and laboratories for research and study, and in the industry they are high-end light sources of the automated optical inspection (AOI) system.
As the heat source, they have been put to use in the thermophysical testing devices and IR non-destructive testing devices in the measuring fields, and in the industry they have been used as the heat source for annealing silicon wafer of semiconductors, as the solar simulators to test I-V characteristics of solar cells, and recently as the heat source for burning the nano-metal ink in the printed electronics field.

  • Strobe application

    Deploying strobe light sources and cameras installed at 6 locations and linked by coaxial fibers, these systems capture images of passing microscopic chips at high speed to determine product acceptability (at rates up to 1,200 pieces per minute).

  • Making active use of multiple light sources for image shape evaluations, current research targets methods for determining the orientation and shape of objects based on differences in the brightness detected when surfaces are illuminated by strobe light sources from various directions. In one example, this method can be applied to measure the size of an affected area, a task that would normally be difficult to determine through an endoscope, thereby increasing the reliability and safety of medical diagnoses. This method also promises various benefits in industrial and disaster rescue applications.

  • Silicon ingot lifetime measurement system

    For various silicon wafer processing and device manufacturing processes, measurements of carrier lifetimes* are growing increasingly important in research and analysis related to metallic contamination and crystal defects. The silicon ingot lifetime measurement system manufactured by Napson Corporation incorporates Sugawara strobes to ensure consistent lifetime measurement meeting rigorous measurement standards.

  • FG-310-U2 & MS-600

    To produce high-quality sounds, the speaker cone of an audio loudspeaker must vibrate in a manner faithful to the audio signals supplied. With a Stroboscope, we can examine high-speed vibrations of the speaker cone when driven by an audio signal and observe them directly in slow motion with the naked eye.*

  • Sugawara nano pulse lights are widely used in laboratories to observe and photograph the airborne state of ink for inkjet printers.

  • Sugawara nano pulse lights are used in research to visualize acoustic wavefronts in various phenomena attributable to sound waves and ultrasound in the 10 kHz to 100 kHz band for applications in medical field and other fields.

  • Sugawara nano pulse lights are used to observe sprays of target substances (such as liquid xenon) illuminated with laser light in a state-of-the-art semiconductor exposure system incorporating a laser-excited plasma light source.

  • Sugawara nano pulse lights are used as light sources to observe the behavior of cation radicals (positive ions) generated in organic substances excited by laser light.

  • Observation of cavitation caused by the screw propeller

    When the screw propeller of a ship operates underwater, a swirling effect called cavitation occurs. This swirling effect is closely related to the ship's propulsive efficiency as well as propeller cracking and damage. As such, cavitation has been a topic of detailed research for many years.

  • Flashlamp system

    Semiconductor development continues to move toward greater density and faster switching speeds.
    These efforts require technology that allows the formation of thin semiconductor layers. Semiconductor layers are formed by injecting impurities (heterogeneous elements) into silicon wafers, a process known as “doping,” and activating these impurities by heat treatment to restore the damaged crystalline structure. If the heat penetrates too deeply, the impurities will diffuse into deeper layers, forming a thick semiconductor layer. Flash annealing limits heat treatment to the surface layer, preventing the diffusion of impurities and allowing the production of extremely thin semiconductor layers.

  • Micro chamber

    Current efforts are focusing on metal nano-ink as a practical technology to advance the manufacture of printed circuit boards by printing. This involves forming conducting patterns by printing patterns using ink containing extremely fine nanoparticles of metals, including silver or copper, then applying heat to fuse the particles. Since silver nanoparticles in particular can be baked and sintered at low temperatures (in the 100°C range), annealing of silver nano-ink by flashlamps with their minimal effects on substrates, is a promising method for creating conducting patterns on various substrate materials, including plastics.

  • Thermal property measurement systems measure the thermal diffusivity (thermal conductivity) of samples by heating one side of the sample with a heat pulse and measuring the heat transmitted to the opposite side and expressing such as a function of time. We can calculate the thermal diffusivity from measurements as long as two conditions are met: no heat is lost from the sample to the surroundings, and the thermal pulse delivered has zero width. While flashlamps or lasers can be used as heat sources, flashlamps tend to be used more often due to their lower cost, ease of expanding the area heated, and compact dimensions.

  • Flashlamps are used to heat the surface of samples, after which surface temperature fluctuations are observed by thermography. Defects, including cracks inside the samples, appear in thermography images as surface temperature irregularities caused by poor thermal conduction at those locations. Flashlamps are used for this procedure, since the heat source must instantaneously heat just the surface.

  • Meat sterilizing system

    Sterilization using UV light destroys the DNA of microorganisms. The absorption characteristics range from 200 to 300 nm, with a peak at 265 nm. Low-voltage mercury lamps emitting 254 nm single-spectrum light are currently used for this application, but attention is increasingly focusing on flashlamps, which offer faster speed, wider coverage, and more powerful sterilizing capabilities.

  • This involves looking for cracks in materials invisible to the naked eye. The material is coated with a fluorescent liquid penetrant that penetrates any cracks before inspection with ultraviolet light. While inspections are typically performed using a UV black light, flash lights offer an effective way to perform imaging inspections of moving samples as part of a process line.

  • Ultraviolet curing is used to harden adhesives, inks, and paints based on UV cured resins. Flashlamps deliver more powerful UV than high-voltage mercury lamps for shorter curing times with lower thermal effects.
