  2. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the laser beam to the material. A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material.

  3. List of laser types - Wikipedia

    en.wikipedia.org/wiki/List_of_laser_types

    Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).

  4. Laser trimming - Wikipedia

    en.wikipedia.org/wiki/Laser_trimming

    Laser trimming is the manufacturing process of using a laser to adjust the operating parameters of an electronic circuit. Laser-trimmed precision thin-film resistor network from Fluke, used in the Keithley DMM7510 multimeter. Ceramic backed with glass hermetic seal cover. Laser trim marks are visible in the grey resistive material.

  5. Die singulation - Wikipedia

    en.wikipedia.org/wiki/Die_singulation

    Standard semiconductor manufacturing uses a "dicing after thinning" approach, where wafers are first thinned before they are diced. The wafer is ground down in a process called back side grinding (BSG) before it is diced. [1] The size of the die left on the tape may range from 35 mm on a side (very large) to 0.1 mm square (very small).

  6. 1951 USAF resolution test chart - Wikipedia

    en.wikipedia.org/.../1951_USAF_resolution_test_chart

    A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.

  7. Smith chart - Wikipedia

    en.wikipedia.org/wiki/Smith_chart

    The Smith chart (sometimes also called Smith diagram, Mizuhashi chart (水橋チャート), Mizuhashi–Smith chart (水橋スミスチャート), [1] [2] [3] Volpert–Smith chart (Диаграмма Вольперта—Смита) [4] [5] or Mizuhashi–Volpert–Smith chart) is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio ...

  8. Electric flux - Wikipedia

    en.wikipedia.org/wiki/Electric_flux

    The SI unit of electric flux is the volt-meter (V·m), or, equivalently, newton-meter squared per coulomb (N·m 2 ·C −1). Thus, the unit of electric flux expressed in terms of SI base units is kg·m 3 ·s −3 ·A −1. Its dimensional formula is L 3 M T −3 I −1.

  9. Laser engraving - Wikipedia

    en.wikipedia.org/wiki/Laser_engraving

    Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.
