摘要： A multilayered wiring board using conductive pillars for the interconnection of wiring layers. Since through holes are bored in the via lands of the wiring layers of the multilayered wiring board, the stress applied between the conductive pillars and wiring layers can be released at the time of connecting the conductive pillars to the via lands. Since the external side face of each conductive pillar smoothly continues to the surface of the via land at the contact section between the conductive pillar and the via land, the notch effect is relieved. Therefore, the reliability of the interconnection is secured even when a stress is applied to the connections during the manufacturing of the multilayered wiring board, and the mounting of electronic elements, etc.

摘要： A supporting member or first synthetic resin sheet with conductive bumps disposed at predetermined positions are superposed on a second synthetic resin sheet under the condition that the resin component of the second synthetic resin sheet is plastic deformed or the temperature thereof exceeds a glass transition temperature so that the conductive bumps are pierced into the second synthetic resin sheet. In other words, the conductive bumps are pierced vertically into the second synthetic resin sheet so as to form through-type conducive lead portions exposed to the first (supporting substrate) and second synthetic resin sheets. The through-type conductive lead portions are used to electrically connect electric devices and circuit and to connect wiring pattern layers. The conductive bumps can be precisely and densely formed and disposed by printing method or plating method. The conductive bumps can be pushed and pierced into the second synthetic resin sheet. Moreover, the conductive bumps can be properly electrically connected to an opposed conductive layer. Thus, the circuit component provides high reliability and contributes to high yield and fabrication efficiency.

摘要： A multi-layer wiring board where a plurality of wiring boards are laminated. The wiring board comprises a flexible insulating layer having a through hole and a wiring pattern formed on the flexible insulating layer. The wiring pattern is composed at least of two conductive layers. The first conductive layer formed on the insulating layer is made of a non-metallic conductor and the first wiring pattern is formed by a laser beam. The second conductive layer is an electroplated layer formed on the first wiring pattern. The first and second conductive layers have different reflectance for a beam. The wiring board is manufactured by integrally laminating a plastic conductive supporting plate wound in a roll shape and an insulating film similarly wound in a roll shape; forming a through hole in a predetermined position of the insulating film; forming the first conductive layer on the laminated body provided with the through hole; forming the first wiring pattern by a laser beam; and forming the electroplated layer on the first wiring pattern.
