  • Publication number: 20070151845
    Abstract: An apparatus for metal plating on a substrate with through-holes includes a chamber that the substrate is disposed inside the chamber to be divided into two sections. A pressure generator and a pressure controller are connected to this and correspond to two sides of the substrate respectively. The pressure generator is used for pumping a electrolyte flowed parallel to the surface of the substrate into the chamber. The pressure controller is used for channeling the electrolyte off the chamber and controlling the pressure differences between the two sides of the substrate. So that the electrolyte flowed parallel to the surface of the substrate is pumped by the pressure generator and it passes several through-holes to control the thickness of metal plating on the.substrate and inner walls of the through-holes.

  • Publication number: 20070153488
    Abstract: A method for fabricating a double-sided or multi-layer printed circuit board (PCB) by ink-jet printing that includes providing a substrate, forming a first self-assembly membrane (SAM) on at least one side of the substrate, forming a non-adhesive membrane on the first SAM, forming at least one microhole in the substrate, forming a second SAM on a surface of the microhole, providing catalyst particles on the at least one side of the substrate and on the surface of the microhole, and forming a catalyst circuit pattern on the substrate.

  • Patent number: 7219842
    Abstract: A scanning unit includes a lamp-mounting body having a top surface formed with an elongate opening that is disposed between a pair of parallel first and second grooves. First and second reflective layers are attached respectively over curved groove-defining surfaces of walls defining respectively the first and second grooves. Tubular first and second lamps are mounted respectively in the first and second grooves. An intersecting line of a first plane in which a middle line of the curved groove-defining surface defining the first groove and a first central axis of the first lamp are disposed, and a second plane in which a middle line of the curved groove-defining surface defining the second groove and a second central axis of the second lamp are disposed, is located on a scanning surface, and is disposed directly above the opening.

  • Publication number: 20060114451
    Abstract: An apparatus for measuring brightness transmitted by a light-emitting display unit of a laser telescope and observed by the user's eyes comprises a focusing unit (11), a sensor unit (12), a processing unit (13) and a display unit (14). A method of measuring brightness includes the steps of: providing a constant color temperature to simulate the external light; providing a tool platform and locating the apparatus for measuring brightness and the laser telescope under test thereon; further providing a light-impermeable cover to cover the laser telescope and the apparatus for avoiding the external light interfering with the measurement of brightness; then turning on the laser telescope and enabling it to range; picking up the light of a reticle and a measured value transmitted from the light-emitting display unit by means of the apparatus for measuring brightness; and at last, displaying the measured value on the display unit of said apparatus for measuring brightness.
