    摘要: Disclosed are a multilayer wiring board, which has a high degree of freedom of wiring design and can realize high-density wiring, and a method which can simply manufacture the multilayer wiring board. The multilayer wiring board comprises a core substrate and two or more wiring layers provided on the core substrate through an electrical insulating layer. The core substrate has a plurality of throughholes filled with an electroconductive material, and the front side and back side of the core substrate have been electrically conducted to each other by the electroconductive material. The throughholes have an opening diameter in the range of 10 to 100 µm. An insulation layer and an electroconductive material diffusion barrier layer are also provided, and the electroconductive material is filled into the throughholes through the insulation layer. A first wiring layer provided through an electrical insulating layer on the core substrate is connected to the electroconductive material filled into the throughhole through via.

    摘要: Disclosed is a reel for winding photosensitive film (6) which stabilizes the winding shape of the film and minimizes the deformation of a photosensitive layer caused by the winding tension. The winding reel is easily carried and stored, and has a sufficient strength to stand against the winding tension of the wound photosensitive film. The user can check the amount of the wound photosensitive film. The winding reel has a cylindrical reel member (10) for winding the photosensitive film around a circumference thereof with a predetermined tension, and flange members (20, 30) detachably coupled to both sides of the reel member. The flange members (20, 30) have inner surfaces which are disposed in opposition to each other and are closed to both edges of the photosensitive film wound around the reel member. By the winding reel, it is possible to wind the photosensitive film around the reel member (10) with a proper tension. Since a width of the photosensitive film (6) is constantly maintained, the edge portion of the photosensitive film (6) is prevented from deforming. The reel member (10) is easily carried or stored. Since the flange members (20, 30) have plural windows (40, 42), it is possible to check the amount of the wound photosensitive film (6) with the naked eye, so it is very convenient to use the winding reel.
