Abstract: A detection method detects cracks with small thickness and solder voids with small volume in a solder ball. The method immerses a washed solder ball into a high absorption material solution for a first predetermined time period. The immersed solder ball is then dried in a vacuum chamber at a fixed temperature for a second predetermined time period. Materials of the high absorption material solution of the solder ball are removed by a low absorption material solution. An X-ray machine then detects the cracks and the solder voids in the solder ball.

Abstract: A method uses a time domain reflectometer (TDR) to determine unqualified clasps of a peripheral component interconnect (PCI) socket. A scanning electron microscope (SEM) captures an image of an unqualified clasp and magnifies the image from a nanometer scale to view the unqualified clasp. An electron spectroscopy for chemical analysis (ESCA) obtains a degree of oxidation at each position of the unqualified clasp in response to a determination that the unqualified clasp is oxidated. A Fourier transform infrared spectroscopy (FTIR) displays a position of the soldering flux using in response to the determination that the unqualified clasp comprises the soldering flux.

Abstract: A LED full-color lighting device contains a control unit, a light source unit, and a light display unit. The control unit relies on at least a potentiometer to apply various voltages to constant current sources, which in turn individually vary the current conducting through the red, green and blue LEDs of the light source unit, so as to deliver light of various colors. The colored light emitted from the light source unit can be easily and conveniently adjusted to fit a user's specific preference and mood. Colored patterns or textures can be formed on the light display unit so that the color of the light of the light source unit would mix with the colors of the patterns or textures to produce a visual effect as if some of the patterns or textures are changed.
