  • Patent number: 11788964
    Abstract: Methods and apparatus for testing solder joints of a PCB assembly using fluorescent-dye penetrants. The use of a suitable fluorescent-dye penetrant may significantly improve the sensitivity of a Dye and Pry test to dye indications compared to a typical sensitivity achievable thereby with a conventional dye penetrant. Some embodiments may use an automated fluorescence imaging system employing a translation stage to sequentially move individual solder-joint parts of a circuit under test into the field of view of a fluorescence microscope and a high-resolution digital camera to capture fluorescence images of the individual solder-joint parts. The movement of the translation stage and processing of the fluorescence images may be referenced to an electronic CAD file of the circuit to enable high-precision automated scanning of the solder-joint parts in the fluorescence imaging system, automated quantification of the extent of cracks in individual solder joints, and automatic generation of examination reports.

  • Patent number: 8906713
    Abstract: Many thousands of micro-LEDs (e.g., 25 microns per side) are deposited on a substrate. Some of the LEDs are formed to emit a peak wavelength of 450 nm (blue), and some are formed to emit a peak wavelength of 490 nm (cyan). A YAG (yellow) phosphor is then deposited on the LEDs, or a remote YAG layer is used. YAG phosphor is most efficiently excited at 450 nm and has a very weak emission at 490 nm. The two types of LEDs are GaN based and can be driven at the same current. The ratio of the two types of LEDs is controlled to achieve the desired overall color emission of the LED lamp. The blue LEDs optimally excite the YAG phosphor to produce white light having blue and yellow components, and the cyan LEDs broaden the emission spectrum to increase the CRI of the lamp while improving luminous efficiency. Other embodiments are described.

During the fabrication process, at least one single-crystal sacrificial layer is deposited on the surface of a base substrate to form a combined substrate, wherein the single-crystal sacrificial layer is lattice-matched with InGaAlN, and wherein the single crystal layer forms a sacrificial layer. Next, the InGaAlN light-emitting semiconductor structure is fabricated on the combined substrate. The InGaAlN structure fabricated on the combined substrate is then transferred to a support substrate, thereby facilitating a vertical electrode configuration. Transferring the InGaAlN structure involves etching the single-crystal sacrificial layer with a chemical etchant. Furthermore, the InGaAlN and the base substrate are resistant to the chemical etchant. The base substrate can be reused after the InGaAlN structure is transferred.

  • Patent number: 8389304
    Abstract: The present invention provides a method for producing a Group III nitride semiconductor light-emitting device, the device including a light-emitting layer which is formed so as to contour a stripe-pattern embossment and to have a uniform thickness. In the production method, firstly, a stripe-pattern embossment having a serrated cross section is formed on one surface of a substrate. Subsequently, on the surface of the substrate on the side of the stripe-pattern embossment having a serrated cross section, an n-type layer, a light-emitting layer, and a p-type layer are sequentially deposited through reduced-pressure MOCVD so as to contour the embossment. Thus, each of the layers is formed so as to contour the embossment, and to have a stripe pattern with a serrated cross section. In this MOCVD process, the direction of gas flow is parallel with the direction of the stripe of the embossment. Thus, the light-emitting layer has uniform thickness and composition in an in-plane direction.
