  • Patent number: 9648757
    Abstract: A method of manufacturing a space transformer includes providing a carrier substrate made for a chip package, forming an insulated layer disposed on the carrier substrate, and forming a conductive block. The carrier substrate is formed with elongated first and second wires. The first wire has an elongated contact which is longer than the width of the first wire. The insulated layer is formed with a hole corresponding in position to the elongated contact. The conductive block is formed with an elongated connecting column located in the hole and connected with the elongated contact, and a cylindrical contact pad exposed at the outside of the insulated layer, larger-sized than the elongated connecting column is connected with the elongated connecting column. As a result, the cylindrical contact pad has sufficient area and structural strength for contact with a probe needle.

  • Patent number: 9587318
    Abstract: Method for continuously producing flexible copper clad laminates includes performing continuous ion implantation and/or plasma deposition on the surface of an organic macromolecular polymer film, and performing continuous copper plating. The bonding force between the copper film and the substrate in a two-layer flexible copper clad laminate produced by the method is much larger than that in a flexible copper clad laminate produced by a sputtering/plating method and equivalent to that in a flexible copper clad laminate produced by a coating method and a lamination method. Meanwhile the thickness of the copper film can be easily controlled to be less than 18 microns.

  • Patent number: 9539611
    Abstract: A method for electroless coating of substrates by applying an activating coat of polyelectrolyte or salt with a first aqueous composition; rinsing the activating coat such that the activating coat not being entirely removed; contacting and coating of the activated surfaces that have remained after rinsing with an aqueous composition in the form of a solution, emulsion or suspension, to form an organic secondary coat; and drying. The activating coat is a solution, emulsion or suspension containing a anionic polyelectrolyte or at least one anionic salt in solution in water. The aqueous composition forming the secondary coat has constituents which can be precipitated, deposited or salted out and which are anionically, zwitterionically, sterically or cationically stabilized. The dry film formed in the process, comprising the activating coat and the secondary coat, has a thickness of at least 1 ?m.
