  • Patent number: 7127812
    Abstract: A board 20 is provided with a Cu film 30 as a conformal mask, in which are formed a register mark 30b and an opening 3a through which a via hole is formed. A camera senses this register mark 30b so that the position of the board 30 is determined. A laser beam is directed to the approximate position of the opening 30a, so that the opening 26a through which the via hole is drilled is formed. The accuracy of the position of the opening of the via hole depends on the accuracy of the position of the opening 30a in the Cu film 30 as the conformal mask. Therefore, the via hole can be formed at an adequate position despite the low accuracy of the position for laser irradiation.

  • Publication number: 20050158553
    Abstract: A filet F is added to a portion constituting a corner portion C equal to or smaller than 90° in a crossing portion X of wiring patterns 58b, 58c and 58d, and a wiring pattern 58 is formed. Since the filet F is added, the wiring patterns are not made thin and are not disconnected in the crossing portion X. Further, since there is no stress concentrated to the crossing portion X, disconnection is not caused in the wiring patterns and no air bubbles are left between the crossing portion X of the wiring patterns and an interlayer resin insulating layer so that reliability of a printed wiring board is improved.

  • Publication number: 20040025333
    Abstract: An opening is formed in resin 20 by a laser beam so that a via hole is formed. At this time, copper foil 22, the thickness of which is reduced (to 3 &mgr;m) by performing etching to lower the thermal conductivity is used as a conformal mask. Therefore, an opening 20a can be formed in the resin 20 if the number of irradiation of pulse-shape laser beam is reduced. Therefore, occurrence of undercut of the resin 20 which forms an interlayer insulating resin layer can be prevented. Thus, the reliability of the connection of the via holes can be improved.
