    摘要: The present invention is to provide a method of manufacturing a printed wiring board with a component mounting pin to connect a printed wiring board and an electronic component. A method of manufacturing a printed wiring board (1) with a component mounting pin (18) at a stage to form a component mounting surface after layers of a predetermined number were formed includes the steps of forming a conductive land (11) on the component mounting surface, covering the component mounting surface with an insulating layer (12) except the conductive land (11) of the component mounting surface, partly forming near the conductive land (11) of the upper surface of the insulating layer (12) a sacrificial layer (14) which can be removed in the subsequent process, forming conductive layers (16, 17) on the upper surfaces of the conductive land (11) and the sacrificial layer (14) with a plating process to pattern the conductive layers (16, 17), forming the component mounting pin (18) elongated from the conductive land (11) by partly removing the sacrificial layer (14) located under the patterned conductive layers (16, 17) and erecting the component mounting pin (18).

    摘要: A multilayer printed wiring board 10 includes: a mounting portion 60 on the top surface of which is mounted a semiconductor element that is electrically connected to a wiring pattern 32, etc.; and a capacitor portion 40 having a high dielectric constant layer 43, formed of ceramic and first and second layer electrodes 41 and 42 that sandwich the high dielectric constant layer 43. One of either of the first and second layer electrodes 41 and 42 is connected to a power supply line of the semiconductor element and the other of either of the first and second layer electrodes 41 and 42 is connected to a ground line. In this multilayer printed wiring board 10, high dielectric constant layer 43 included in the layered capacitor portion 40, which is connected between the power supply line and the ground line, is formed of ceramic. With this structure, the static capacitance of the layered capacitor portion 40 can be high, and an adequate decoupling effect is exhibited even under circumstances in which instantaneous potential drops occur readily.
